What the heck, I just blew my head gaskets out last week, small world...LOL, wonder if anyone can point me in the right direction as far as a good ford eng builder to swap the internals on my stock 347 to a dart block 347? My old eng was built by Slaters auto works in Housten and it held up really good until it got run with 82 octane at 12 psi. I would take it back to Slater but he I think is just too busy .....
thats why i like my factory stock block ..never a problem..i dont have to be the fastest on the block just ride around ....happy miles...!!!
Call Chris Car Doc in humble.
Ford Strokers was my go to when I built mine a few years ago. Woody is the man.
I really like how you share this type of information. Sharing the good and the bad makes real content.
We gotta get this info out there to the public. 🙏
Shout out to Matt for catching that on his end, while reviewing the data log information! I've never heard about the tps doing that either. Great information Brew2l! Car is looking and sounding great..👈💯🔥
He’s the man! I’m gonna nickname him DR. Tune for that catch!
We’ve had this happen before and learned from it for sure!
You have no idea how much I personally appreciate this channel .The connections of great people here are what keeps the stress during a build at a minimum.Keep up the good work brew!
Man what some crap luck, the good thing is you only blew head gaskets, no engine damage, still a lot of work for a aftermarket TPS sensor, great information video again BREW2L.
Awesome info as always man. Glad you got it sorted. You are a pro at swapping head gaskets. That little rip at the end was wicked.
A whole community learns a great lesson when you post this, and that's what makes great content, and you can't know *everything* , we are all on a journey. It takes beans to show the things that go wrong !
So true 🙏
Sorry bout your luck there bro. Glad you got it sorted out for sure! That thing sounds beastly!! And thank you tons for all your info too. Im running a 88 speed density setup in my 85, and most of your information (only a few things dont apply) has really helped me get it dialed in much much better. Gonna have to get it tuned after i get the cam and injectors swap done this spring. Looking forward to what you got coming next 👊
Bad ass stand brew2L
Great vid, and props to you for openly admitting a mistake. Too many guys fake it for YT and that really hurts guys that are learning. Another killer vid, thanks brother I’ve got a retro fox tribute build going myself. 😎
Just wanted comment on the vid. great info, and am greatful for your hard work and your team. You've inspired me more and more to learn and be patient with. Have a SN95 Original Block , bottom end, cam ,heads and intake. I've swapt out the original Rear end gears to a 3:73 and could tell an improvement. I get there a little quicker. Next moving to Anderson Cam, can't wait....
Love you guys and thanks for being who you are, I know I need ya 😉👍
Sounds good, and glad you got it figured out. It's gonna be a Street Beast. 😎
Thanks for sharing brother 😎
seems lately I've had nothing but fail videos also, thanks for keeping it real Brew2L!
It happens… 😞
@@BREW2LFOXBODY for real! victory will taste that much sweeter!
I just love this car more and more. Just amazing! Thanks for another great video.👍
Thanks bud!
Hell yeah @ the 11:01 mark! 👍That's how I love to drive my cobra! That's my favorite thing about a mustang. Sure other cars can get the ass swinging out sideways.... but it's just not the same! Glad your engine is safe. Great video and information Nakea.
Hey BREW2L, I know I'm a broken record; The ECT could save your engine as well. It plays a huge factor in the timing with these cars because it tells the ECU what temperature your engine is at which if it fails cold you will be out there giving it the beans and things like this could happen. I don't know if you've ever changed yours out but it's a cheap part to do before tuning. Back in the day when I had my coupe, I went through so many throttle bodies and TPS sensors chasing the demons in my car. One day was like I'm just going to do basic maintenance on this part and damn it fixed all my issues. Had a great setup and all but a stupid $15 sensor caused me so much headache and money
Definitely I change mine every couple of years for that reason.
Been playing with 5.0’s for 30 years……had no idea about the 5v timing thing. Thanks a bunch for sharing
On the plus side looks you’re running Fel-Pro 9333 gaskets. Great gasket for supercharged setups as it seals very well but will let go if the motor rattles. Always better to blow a gasket than the hard parts (pistons, etc)
Great video. Very informative as usual. I'm not boosted nor do I plan to. But there was some beneficial info in this, for me.
👌
Learn something everyday. I need to check mine tonight on all my cars
I had the same issue a month ago, I was doing some pulls with my turbocharged fox running 6 psi only
And I started to hear that rattling noise in 3rd gear, and I thought something is not good.
So my car shuted off, of all the sudden, and had to tow it home
And when I was inspecting it, I realized it was mixing oil with water.
Decided to remove Al the spark plugs and 6 of them had water.
I thought the engine was not good anymore but now that I saw the information you said, it makes sense of what happened to my engine.
Thanks a lot Brewl2l
Great info! We live and learn.
Loving the sounds the Retro Fox is making 👌
Thanks brother! Me too.. she’s almost ready for a full thrashing as well! 😆💪
Great video brother I shared it with to my page for all my mustang fans
Thanks bro I appreciate that 👌
Great information shared. I’ll definitely be checking my TPS at wide-open throttle now. Always something to learn about these cars isn’t there?
This is good to know. I've had my 89 for a couple of months now and making some tweaks and changing vacuum lines. Fuel tank had rust so I replaced it and the pump. Also found some debris in the injectors.
As I am getting ready to do my car I appreciate that tip!!
😎👌
Damn Brew2l Good video...so tired of changing head gaskets. I really been thinking about going coyote but I just dont want back track... I have a 347 turbo car as well I will be checking this asap
Sounds great 👍
Good Informative Video!!
Tps is my mortal enemy LMAO. Great video brew2l
Mine too… I hate that thing 😂
Great Video
10:48 When you know shit is about to get real lol
I use to not care to much about the supercharger whistle on those style superchargers back in the day because it was a dead giveaway but now I love it and it is sort of a flex. Lol man the retro sounds great
I’m truly enjoying this build. It’s so fun to drive and the sound is awesome 🤩 thanks brother 🙏
OEM ECM issues. 😅🤣😂
Old school technology. 😎 vid bro
I def love the sound of the retro... it thumps and lets you know theres something hiding under that hood... Thats the big issue I have with my cobra the turbo hides all that music to your ears
Any idea if Matt is going to be posting some videos of your tuning on his channel? That would be cool to see what he finds from his side on your build!
Thank you for this good video
🙏
Wow thats crazy, but if it's rare and bad it will happen to one of us. Glad it wasn't worse she still sounds amazing
Exactly! I wonder how many cars suffer from this and have no clue what the cause is.. 🤷♂️ thanks brother
Boy she came alive when you stabbed the throttle. I might have to ditch my nitrous and get a vortech. Car sounds awesome!
Btw, I am planning a na build & plan to stay eec-4 so good info!
Budget allowing either a SBE or Windsor stroker. Looking for simplicity & torque. 👍
You’ll love it 😍
Thanks
Very informative hope I didn't blow my head gasket.
Is there a issue 3.6 v @ WOT ?? Thank you awesome vid btw !!
Glad she's good buddy, damn these cars will bite you in the ass every time
Every time bro! 😂
DUDE!!! I have a 93 cobra, heads were 3 angle valve job, o ringed, stock bottom, S-trim straight cut, 90mm maf, 70mm Tbody and a blower cam. Continually blew head gaskets, blowing coolant out the overflow. I sold the heads and block and bought a used gt40 engine. Haven't really had problems since but I wonder now if that was my problem. Thanks for the video, I will check that!!! Now 414rwhp 395rwtq. 434rwhp on a mild tune with methanol injection.
That sucks!! I don’t have a supercharger, but I’m still nervous about my BBK throttle body and TPS. Im gonna go get a motorcraft sensor.
When you hit it I was like hoooolllddd up let’s see that again ! Lol
😁✊
When you were driving what did you have the camera stuck to? Was it the passenger seat head rest?
Seeing this video makes me want to get my Foxbody done so bad!!!! 86 TTOP with a aero front end on it. It’s a 306 and I have a on3 turbo kit I want to install this summer.
Great video man! The Retro is becoming my new favorite! I can’t remember if you’ve ever mentioned it or not, but is this car running just a T5?
Thanks, yes it’s just a stock T5

Seeing this video makes me want to get my Foxbody done so bad!!!! 86 GT with T-TOPs with a aero front end on it. It’s a 306 and I have a on3 turbo kit I want to install this summer.
show us how you make the log for those of us that never have done one, walk us through it!
Always gotta snatch 2nd at least once when going out in the fox
Hey what shifter you have in the Retro Fox? 🦊 It has a nice positive click going into every gear! Is it a Pro 50?
Have you made your TPS adjustable? I have found that even new TPS's out of the box are not all the same at base idle. I fixed this on mine and was able to dial it in by doing this.
Man it sounds damn good wide open throttle 👍
You need to find a Systemax 1 lower intake for the bread box upper.
Once again this is why i coyote swapped. You can go through a9l, quarterhorse, pro m etc but you still have the trash pip sensor, salt pepper shakers, tps, iac… no thanks. Every time i started the car it was always something. Carb or New Harness is my answer
Never would have thought that. Good info but hate how you found it. Car is awesome!
I’m just glad we can pass the knowledge around! Shoutout to Matt over at Leech Motorsports!! Aka DR. Tune 😎
@@BREW2LFOXBODY yeah if I ever get where I wanna be with the car I’ll be using Matt
What setting you had the meter on.
had you already adjusted your tps before you showed how to in this vid because it was below 5
Do you have arp head studs? I’m getting ready to do head gaskets on a car I’m just selling and trying to decide if I have to do new studs and if I should go ahead and flip the bill for ARP.
Surprised it didn’t trip a code. I always like to retard my supercharged timing to boost, which is an overlay to the stock computer like in an MSD BTM I discuss in one of my videos. Always need to know your max boost WOT timing.
The tune was set at 16 degrees total timing and mid 11s target AFR.
So are you still enjoying the tps based eec-iv? Not to sound cocky but i've had so many problems with the speed density on my 93 f150 5.0 from 1800rpm idle, dies at idle, detonation, and running extremely rich, replaced sensors checked everything but intermitent problems are a bitch. Now im running a map/vacuum based megasquirt 3 for about a year and coudn't be happier, and found the problem was in the sensor ground on the harness i've yet to fix it right but the jumper wire is working fine. Now even though the detonation killed the rings and it has a ton of blowby i've unhooked the tube from the valve cover to the air box because the air filter was dripping oil but it still runs better than it ever did before and gets 1.25 avg better mpg. So i'm getting ready to drop in a rebuilt 351 and 4r70w with all new holley harness for sequental injectors and individual coils with russ proteous ecu. But i wish you the best with the EEC-IV!
Hey what head gaskets are u running with boost, I had watched a video of yours that u told what gaskets u used and cant find it.
Would the TPS setup change any for an AUTOMATIC car?
I just put headgaskets on my on3 turbo 89 lx and I had it dyno tuned. Crazy is the car idles like crap and even the tuner said no matter what I did with the tune I can't get it to idle so I changed my IAC valve and It got worse so I'm starting to think it's my tps maybe? It makes me not even want to drive the car because you let off the gas it dies or surges and dies .
Not related. But I just want to throw out there replaced my IAC sensor and this fixed my a/c !
👀👌
@@BREW2LFOXBODY the car would idle down with the a/c on. The compressor would turn on and off, and the car would run like crap. Just changing the sensor out to a brand new motorcraft unit fixed all of these issues. Compressor stays on and idle doesn’t dip at all when the ac comes on
gotta watch them ther tps sensors..i had one once that the plastic inside was slightly damaged somehow..good tps but every now and again coming off the interstate after some heat it would slip off the (flathead screwdriver) on the throttle body causeing a surge condition..finnally figured that out..new one now no problems..(set at .95 volt)...
True!
What was the fix for the 5 amp reading?
any idea why my 91 kinda breaks up till 3500? after 3500 its like its a whole new car lol. deleted all the emissions and calibrated all the sensors and timing, new plugs and wires gapped at .50. kinda thinking the distributor or my plug gap is too high. gonna figure it out in the spring any advice would be appreciated. 91 lincoln mark 7 aod
Hey bud did you get rid of the lightning?
I would never run an EEC-IV of any kind for a supercharged car, nitrous car, or a weed eater. He already has a Term and a Megasquirt, how he didn't learn his lesson is beyond me.
New to the channel. Any reason not to run the Holley Terminator x? I've used it on a few setups and it is outstanding.
Nothing wrong with either one. It just comes down to cost and ease of install for most people.
I was always curious to what would happen if the tps went over 5 volts. Now i know. I always assumed 5 volts was out of the range for it to read and it simply wouldnt read your throttle at all.
I misspoke on it going over 5v. By it just reaching 5v causes the issue.
Initially it will default back to 1.25v reading, and if the vehicle is moving, that will immediately trigger a decel condition where the ignition timing is fixed.
Terminator x would have protected you, terminator for PRESIDENT
He was already governor and that proved to be too much!! Haha
I have the Terminator X waiting to be put in. Already have a chip and just want more programmability and safety net when the turbo goes on.
Wow just checked mine.. .98 at rest and 4.60 wot. I recently popped a head gasket on my car so this let's me know it was something else.
Nice! Glad you checked it. At least now you know 👌
This is key on? I'm getting 4.9 V with the throttle closed on a new tps. I'm not sure how I'm getting that!
I ran p heads on my 88gt. Kept blowing head gaskets. Block was checked heads were milled. Changed to different set of p heads same thing. I always ran my tps @.92/93 resistance. I now wonder if the tps was spiking. LOOKING FOR A 82 TTOP COUPE ROLLER OR COMPLETE CAR. ANYONE KNOW OF ONE?
Paper gasket on a boosted engine ?
I see a lot of people going back to stock computers lately all due to idle issues and what not with say a terminator x. However stupid crap like this that ford did keeps me away from stock. I’ll tune and tune and tune my idle forever as long as I avoid errors like this because of stock ecu setup. Has holley gotten their setup 100% plug and play, no. However I still think is far superior over stock units.
Would that happen with nitrous as well? Wonder if that’s why we kept blowing head gaskets all those years ago.
Absolutely! I would bet this issue has been the unknown cause of many blown head gaskets over the years.
Please get some Torque boxes in that thing. That boosted power will destroy them
The vref pin is the reference voltage signal from the computer...it "should" never be more than 5v...I would surmise that either you have a short somewhere in the harness, or somehow the computer output > 5v. Which, I suppose is possible, those computers are freaking ancient by today's standards...electronic components do wear out, contrary to popular belief....you might want to pop open the computer again and make sure one of the capacitors hasn't shit the bed (very common on old EEC-IVs) and possibly creating a short that allowed the vref to go > 5v.
I shouldn’t have said OVER 5 volts. The issue occurs @ 5v
Because the aftermarket sensors are slotted to permit some level of adjustability. It is certainly possible to get the sensor out of its optimal range. Once the car was back together, he just had to loosen the screw and back off the sensor a touch and the voltage dropped right back down as it shows in the video when he did the voltage test.
@@BREW2LFOXBODY ah, gotcha...the OVER thing threw me for a loop :) ....I suppose the programming isn't expecting a true 5v to mean you're still in WOT...that's a poor assumption by the original programmers!
Mine run hot and busted the heater core after bumping the timing up to 14
Any preference on brand of TPS? Or just don’t buy the cheapest one? Lol
How much does Matt charge for the tuning?. I might get with him when I get mine going
Give him a shout over on Facebook or Instagram. He’ll hook you up👌
How did you not check tps you always do
Same thing just happened to me 2 nights ago, was on my way to pick up my truck from having th ac evac'd, so i can replace a line on that, and like halfway to the place noticed the car was running a line over normal temp on the stock gauge, at first i thought it was just a bad thermostat, let it cool down, topped of the rad with water, but then on my way home it started missing real bad, never overheated again on the way back home. But sure as shit, started it up first thing the next morning with the rad cap off and boom coolant everywhere! Only thing i can figure is my fuel pressure guage is shit, and in turn i may have adjusted the fuel pressure too high, dont know if thats possible, but the fpr was literally the only thing changed like an hr before the head gasket went. From the stock one back to an aeromotive i had to fix a leak on. But im gonna check the tps voltage too before teardown, for shits n gigs.
Damn that sucks brother! I doubt the fuel pressure played a big role but I’m finding out anything is possible….
@@BREW2LFOXBODY it sure does buddy! Im kinda thinking the same thing too, but i do know it was running lean for at least a day or 2 before i noticed the fpr was leaking. Gonna go with the race gaskets this time, see if theyll hold up better, gonna have the heads pressure tested to just to be safe. But your sure right about anything being possible lol, just glad it only was driven a few miles after it happened.
@@nunya2814 oh I didn’t realize it was running lean… yeah that could have definitely been a problem
@@BREW2LFOXBODY ya it was running lean for at least 2-3 days before i realized the reg was leaking, no evap canisters on the car so slight gas smell from engine bay wasnt immediately alarming. But after a fill up, the smell got real bad and said something aint right lol, saw it leaking out the side port ran the stock fpr for like 2 days, til i had time to clean up and fix the aero one.
@@nunya2814 Maybe that was the problem. Be nice to know for sure. How did the plugs look? Other than being wet of course lol
Time for some mickeys on the back . She was side steppin
It actually has drag radials on it.
Dam mine hooks pretty hard
Great channel by the way I really enjoy your videos
love your videos my man but you got to stop with these budget efi systems. Look into a Pro M EFI system. A bit more up front but worth every penny.
Converts your fox to obd2 and would've picked up the tps problem in a second.
People still use carbs and filing cabinets also but to each his own.
Not sure how it would go over 5v when your supply shouldn't be over 5v?
5 volts is the trigger for the issue . I just worded it wrong I guess.
Just to clarify for myself. You set the tps at closed throttle correct??
Yes, then check voltage as well at WOT just to ensure it’s not at 5v
If the balencer on a pushrod 5.0 slips, you got real problems. Sheared keyway or some shit
The outer ring can slip around the rubber cushion
@@BREW2LFOXBODY you have a point 👉
Hey brew2l. I probably missed this in a different video but what trans is in that fox?
Stock t5
@@BREW2LFOXBODY thank you for the reply. I appreciate it! Have a great night!
Thanks bud 😎
Keep the Radial tires on it so the 5 speed don't go Notorious bad design lol
It’s got drag radials on it now. A set of wrinkle walls will be going on at some point 👌
Retro vs Calypso supercharged vs turbo once you get it dialed in.
Can’t wait for that one ☝️
Could very much depend on the rpm you leave from if it's a roll. Or the driver if it's a dig. Turbo cars have so much TQ down low that they may either have traction issues at launch, or a great head start if it can hook.
My buddy has a turbo and I have a Vortech. He has over 100 ft lbs advantage at 3k rpms. We even out up top, but a centrifugal can't claim the same low and midrange numbers.
It’s definitely going to be interesting 🤔
@@BREW2LFOXBODY just let Andrew drive the one that you don't want to win 😁
Only teasing because his black car was a C4.
I was gonna say that actually 🤣🤣🤷♂️

Right here
Which head gaskets did you use?? 🔧🔧🔧
9333’s
Do you use the same ones on your turbo car? I’m currently putting aluminum heads on my turbo fox and looking for the “best” ones to use
I use cometic gaskets on the turbo car. It’s all a matter of opinion honestly. Some people like the head gaskets to be the weak link in case something happens like the TPS deal. Others just want maximum sealing capability.
That’s what I’ve been looking at. Some cometic mls.. just figured I’d get your opinion and see what you’ve had good luck with. I appreciate you replying man! Love the channel. Keep rockin with it bro 💯💪🏼🤘🏼
Sorry man...
It’s all good! We got it done and learned something in the process
Never trust the STOCK computer
