If you got 300 degree oil temps, that oil needs to be changed no matter how many track days are on it. My GT350 is tuned with long tubes and E85 or 93. Really woke it up. Runs great and sounds mega !
Absolutely, the oil was cooked, literally haha. I’ll be changing it very soon. If my car stays reliable I would love to do the same. Long tubes and a tune would be a welcome addition.
Picked up 65-70 lbs feet torque down around 3-3,500 rpm. Peak torque gain was 31. On E85 I planned on doing a couple track days this year but didn’t get it done due to covid.
Dont know how much hes improved since but its crazy to see you on record a full 7 seconds up on scotts time in his GT when he did sebring. Awesome to see how quick that 350 is.
Just picked up a ‘16 350 with 4k miles. I’ll be watching all the videos now. Also got some Adams wash and polish to keep her looking good. Next order is resonator deletes
Jeff Ashton what oil you running? I have a 91 bronco as a daily, so she’ll sit every now and then.. only when no rain in forecast. So i have heard amsoil is pretty good for this motor
Love this series ! Couple of points to help out I am by no means an engineer But absolutely love mustangs And worked on them for a long time ! #1 you need a bigger radiator “ thicker “ And you can opt to go for a O2W which basically cools it down using water instead of air which could help aerodynamically because you can make the air entrance smaller however it’s very complicated so i would just opt to bigger rad + Higher Watt Fan #2 when you are tracking take off the hood vent helps decúplate heat Wayyy faster “ GT500 even tells you to remove hood vent “ #3 since You now have way more aero parts to feel a huge handling difference opt for some Carbon Fiber Wheels ! Trust me difference will be insane #4 get a Carbon Fiber Driveshaft “ will do wonders “ #5 suspension is good however can be upgraded to something a bit more stiff and lower “ not too low “ As it will struggle in straights #6 remove A/C unit as well to make more space for rad #7 sounds crazy But adding some insulation after radiator will help tons , that way the air can more easily cool off the rad since the heat produced by engine won’t affect the rad much And i mean adding it like a wall after rad And not right behind the rad which would absolutely destroy the cooling since air can’t pass through
Omg man, your videos are scaring the hell out of me. My 2018 with 4K miles on it just did the same thing to me yesterday that yours did when you had to have your engine replaced! Knocking the same exact way... have to start making calls to dealers in the morning about bringing it in. Hopefully they’re as good about mine as they were about yours.? Quasi purpose developed and built track car and the engines doing this after 4K miles...! So upsetting and disappointed to say the least. I thought you were done with the issues until I started digging into your page more and found out about your continued problems makes me want to get it fixed and then get it gone 😡 I had such high expectations for this car and was so excited about using it for what it was intended for but now I have such major doubts.
Nice vid Jeff. Yea I had the same experience recently when I switched out my coolant tank and wanted to make sure I had enough coolant after the exchange. I have a 19’ and it uses the orange coolant. Love Sebring! My first track days were there. Yea too bad that guy slowed you down closing the finish line. That looked like a really good lap.
Hello Jeff, I saw you had a tilt bed trailer, which I do also. So my question is what height of ramps do you use with it after you added the new splitter? I have a 20 ft bed with 6 inch ramps and still slightly drag when loading and off loading. Thanks, really appreciate the videos.
Thanks for the Sebring track video especially since they are hard to find with the GT350. Just out of curiosity where are you getting your line from? Turn 1, 5, and 17 you are leaving a ton of speed and track on the table with such a short tight line. You have the aero to handle a much wider track out gaining you a lot more speed
Run my gt350 on the tail of the dragon all the time since it is local for me. That is a 2nd gear road most of the time and I push it. Oil temps on a 85 deg day reach 265-270 at the bottom of the hill when I finish. Just posting this for others to comment on their oil temp stories. Anyone else have cooling issues?
Any Jeff Ashton videos are appreciated! I would love a new series called “Jeff Ashton” builds your Custom 2015 Mustang GT into a Whipple Beauty, for subscriber, yes I’m trying to tell you something Mr. Ashton Congrats again on your new family member. And stay save you and your family.
Jeff Ashton I have one that would love the touch of the “Evil Genius” through the whole whipple build it was Amazing I watch those videos often and at the end the Hood you had on her OH my 😍 Love at first site Mr. Ashton things are crazy now, and your very busy with your family, but if you go back to you tube it could be “Pimp my subscribers mustangs” Lol
Ugh, temp doesn't really bother me seeing how ambient temp was around 100. Probably closer to 120 on tarmac. Throwing Belts is kind of disconcerting. Maybe this specific gt350 is cursed and not meant to be. I'm also not 100% sure on the new ones either. I've looked at a couple 2020 and trust me the dealership GM told me at the auto show he wants it gone and would make me an incredible deal, but I still have concerns. As much as I am a Ford guy, I am really leaning towards manual a C7 grand sport. Regarding trailer set up, 8ft ramps definitely help, when I got mine it's the square nose front I believe they call it the "race series" and I went with a full 22' deck. Leaves me enough room in front to mount a tire rack against nose bulkhead. Have fun with the your child, enjoy the innocent younger years, they grow up fast. They're not quite as enjoyable when they become teenagers 🤣 every day becomes an adventure.
Shredding serpentine belts is almost unheard of on newer cars. Many of them last the lifetime of the vehicle unlike years ago with the V-belts. You either have an alignment issue or your tensioner is malfunctioning or needs replacement.
Fantastic video!!! Wow hearing about upur belt breaking. Has Ford have anything out regarding belts breaking. I also like the track video. That Shelby sounds awesome
Not sure if I missed any details in the vid regarding this, but I'd be concerned about pulley alignment if you threw the belt and that lead to the coolant overheating. If you get a chance, definitely get the pulley alignment checked with a laser alignment tool, if you haven't already done so. I had a belt shred and snap, which took out the ac belt and lead to spraying coolant out of the emergency drain on the overflow tank on my c6. It ended up being a pulley misalignment on the supercharger pulley and the alternator pulley. They had to shim the pulleys to get them aligned.
How come there's no new videos? I miss your content. I just bought a brand new 5.0 PP2. I keep asking myself why I waited so long, this is the most fun I've ever had driving before.
I'm surprised the 2.7 does the job well. I was looking at 3.5 Ecoboost F-150's for a while but, looking to just keep my 08 F150 4.6 for now and go with a Futura or Trailex. Thanks for sharing.
Why are you using coolant in the first place? Use straight water. If you’re tracking the car a lot then water is the way to go for many reasons. You’re in south Florida, you don’t need antifreeze anyway. And if you spill on track then it’s just water and you’re not going to black flag a whole session.
Old post but coolant also has lubrication and anti rust additives. Distilled only on a road car will lead to something bad happening. And Ford will not honor the warranty with water only in the coolant lines. I run 70/30 mix in my track cars.
Thanks Jeff you have the 350 looking really nice I want to trade in my GT but I’ll wait until a good deal and the value of my Gt be the same as trade in
Like A Mustang GT Or Ford GT Lol 🤣 But If It’s A Mustang GT, I Think You Can Get Like $30k For Trade In For Sure, I Would If I Had One Since Shelby GT350 Prices Are Under 50k And Super Affordable
@@johnnyjayy14 That is exactly what I did with my 19 GT PP2. I found a good deal that was under sticker on a 19 GT350 Track Pack about 2 months ago. If you can get the deal done, you will not be disappointed!
Replacement engine? Really? Wow, you’re calm and reasonable during the overview. If you’re throwing belts after the engine swap I’d take it back and get them to replace everything on the front of the block since the new motor, most likely, did not come with a new serpentine setup.
I negotiated a 7 year 100,000 mile powertrain warranty out of it. Obviously wasn’t happy, but gotta make the best of it. Doesn’t cover the basics, but I hate taking my car to dealers so I’m probably better of fixing the miscellaneous stuff myself.
RE-71R, very impressed with the tire especially considering the conditions. Event when they start to get a little slick toward the end of a session they are still predictable which is nice.
Jeff Ashton ah ok. I figured it it was something sticky. The issue with 71rs is that they wear super fast. But when they last the only comparable tire is the Yokohama ad052 or the viper ACR tires
George K. The a052 has just as much grip as the 71r’s and they last much longer. Our global time attack series has moved to a052 as the spec tire. We saw almost everyone’s lap times improve which is nice. And of course more durability is always welcome.
The yellow/green coolant is backwards compatible to the old pink-ish coolant, just fyi. You can use it to top off or replace pink coolant. What they said is that if the car didn't come with yellow/green or pinkish coolant then the yellow/green coolant isn't compatible. www.fcsdchemicalsandlubricants.com/quickref/FCSD%20Motorcraft%20Yellow%20Antifreeze-Coolant%20Backward%20Compatability.pdf If the pink coolant is cheaper, that probably was the better call though. The green coolant is supposed to last longer than the pink coolant. The change was made to cars made after January 1st, 2020. www.mustang6g.com/forums/attachments/ford-coolant-pdf.486031/
And regular green.. the manufacturers are finally going to the yellowish green because it is what everyone is using these days in professional situation
Old post but here’s the answer. Oil must reach 120 at least to vaporize water in the oil. And that means with no thermostat it’s a long warm up time to get to temp. A GT350 uses 50wt oil so operating temp is very important as well. Many other reasons to make the engine get to temp faster.
Haha, that was an epic one, I’ll be sure to post it. Nothing like cutting a big hole in a perfectly good hood! I have some good tips on the install that should help too.
Hope you guys enjoy the video! Is my GT350 trying to tell me something lol?
Miss seeing you on mustang lifestyle... that is what she saying lol
Yeah its time for a GT500
Mardi styles don’t say that!!! I always catch myself looking and need to stop haha. 😂
PLS show us the installation videos...PLS
Anything specific you’re looking to see or everything in general? 👊

how does the car changes and what are the benefit of the long tubes setup?
@@amineghostdog I would imagine it feels better down low. Gives it that feel of torque that it lacks stock.
Aaron do you track your gt350 with that set up?
Picked up 65-70 lbs feet torque down around 3-3,500 rpm. Peak torque gain was 31. On E85

I use 8 ft ramps plus race ramps. So around 13ft total. Most cars would work with the 8ft, but my front end is inches from the ground.
@@JeffAshton thanks, i have a GT350R and am thinking about the aero package you did. I would assume I need longer race ramps than my 6ft. Thanks
Very much enjoyed that track footage. You've improved her much since your last video, get those install videos out bro. She looks like a true GT4 now.
Great Video! I really want your setup one day! What truck are you using to tow?
Watch starting at 12:45 I talk about the towing setup and my truck.
Should have kept watching! Lol

TCR 223 2015-2017 models do not have oil, tranny, diff coolers. That’s why so many overheat at race tracks.
I think after the initial launch when the tech pack and track pack were a thing the "track pack" came standard in 2017

Just drain and flush put new coolant orange and gold suck. Had issues with these coolants over the years.

What springs are you running
Install low temp thermostat. Helps
I want a 350 but not yours Jeff. No offense
Good luck with one. Might just blow
Or can be caused by an belt same as a tire that would be considered a coffee cup when is is longer than the other Edge or radial pull
Does the GT350 have wheel hop upgrades?
No chassis stiffening yet, will eventually upgrade to poly bushings. :)
so the gen 2 motor blew up?
wish i lived near sebring.
I'm more saddened that you don't answer any of the questions put to you on your TH-cam videos!
