2020 GT500 Long Tube Header Test!!
ฝัง
- เผยแพร่เมื่อ 25 ก.ค. 2024
- More often than not, multiple modifications are done at the same time so it's hard to gauge what each part is worth. After getting a lot of questions about headers on the 2020 GT500, Rarefab installed a set on our test car with no other changes to see exactly what they are worth. Keep in mind, this car is still running the stock supercharger pulley, so any gains we see here will only get much larger on a higher boost setup. For this test, we chose 2" Kooks Long Tubes which you can pickup right here:

It sounds awesome. I still can't get over how good it looks in blue.
What blue is that?
Bradley Pfeffer looks like velocity blue
2020 color is ford performance blue metallic
900rwhp on stock blower pulley ratio is insane. Amazing what we can build today
for real. I remember thinking back in the day that nothing like that would ever be possible
900hp is the new 500hp 😂💪🚀🏎🇺🇸 Crazy how 600, 700, 800 seems normal these days!
Yup, back in high school in the 90s I thought my neighbors z28 with 275hp was a lot 🤣😂
That blue is sweet! And those headers looked so clean under there and sound great!
@@yardhostler3728 facts man. Like in the early 2000s 300hp was very respectable power level and you’d see that in top of the line sports car sedans and certain sports cars.
Vs now your see 300 in like your average V6 grocery getter.
It's always interesting to follow the work that you do with this machine ! But honestly, Every time I see that Car in that Color my heart melts ! And the sound, Damn !
Great to see your passion is still alive and well keep rocking man great video.
This man and that shop is super legit. If you got a S-550 Coyote Mustang 5.0 or a beast of a GT500. You have to take it to this man and this shop ASAP.
Nice gain at the rear wheels for stock pulley and stock blower!
love the GT500 that is my dream car keep it up love the videos
Great power gains, can't wait to start doin some mods on my brother's gt500
Coming along great Ken!
Soundgasm! Absolute Soundporn! Well done!😍😎
Ken, I appreciate and respect the methodical approach to the modifications and testing you are doing. I'm in NY and can't get away with the same "kind of fun" Floridians do. I've done a number of mods to my own '20 GT500 but can't ditch the cats as much as I want to. Thankfully, they can't stop the want so I watch these videos with a jealous grin. Keep up the good work.
Right on
I'm sorry you can't enjoy your freedoms like other Americans 🙁
Eh I've been Catless. You should have 5 years before inspection no? I know a lot of guys in NY/NJ running no cats
Only muppets delete cats
@@732Mopars Nope. Still had to obtain an inspection sticker. I stood right there as they plugged into the port and answered questions.
Your car looks Mint Ken!
Thanks for the informational video.I am interested in seeing just how much hp is gained from porting.
875rwp with bolt-ons , just letting the engine breathe while still using factory pulley's/factory blower !
That factory blower is the largest TVS blower on any factory vehicle.
Those blowers can make 1kwhp without much work.
Good job. I really like testing of single components. In many instances people will say they put on headers and got a result, but they also changed x, y and z at the same time, so never really know the true effect of the component.
Long tubes only add 20wheel. So $2500-$3k total for 20wheel. No thanks
Those headers look really good.
Those seats! Those wheels!!! 😍🚀🚀
Cool video, gains were good. I'd speculate 910-915hp after the ported blower and throttle body upgrades, maybe more. I guess it depends on who does the porting and what throttle body you use. GD LUCK 👍, more power is Good
Man that thing is a beast.
My car will make it to Palm Beach Dyno very soon. Getting the headers installed in my car over the next few weeks.
Sounds great!
Did you ever post results from your S/C porting ?
The reason i suggested this is that i have 2020 gt500 and I'm interested in shaving weight also
And thank you for the great content again 🙏
Awesome! Shaving weight is always great but I wouldn't take such a great piece off of the car like the brakes. The Anderson carbon hood weighs 20 lbs less than stock. That might be a good place to start
@@PalmBeachDyno will consider it.
Sure thing i have no intention to ruin the way it drives
Great Vid. Very informative! Did the car loose any boost from the pre header runs from the larger primarys and headers?
Great video Ken
Thanks 👍
Looking forward to see just how much hp porting produces.
Sounds good and showing some gains!
8500RPM on this V8 sounds so scary to me when the stock is 7500. Curious how that'll hold up long term.
Probably not long
I noticed he does that (pulls to 8500 on his dyno runs). I would hope not on customer cars.
@@maximusvonce1381 over two years later. Cars still run like this and hold up perfectly. Thought you should know.
Dam that mustang looks and sounds good.
Nice work, love how that dct rips through the gears. Any concerns about how much more power the dct can hold?
Freyja Frigg the 2020 gt-500 has a dct trans not a 10 speed auto. Nothing out there shifts as fast as a dct transmission.
Palm Beach, where did you get those awesome seats??
Ken, at what point will 1-7/8 headers become a restriction ?
WOW great stuff but i wonder for each state what the EPA regulations and emission regulations are and how many cars out there are technicaly not road safe or even roadworth due to the emissions regulations in each state, just saying that all, not once have i seen any upgrades to any cars performance which still keeps the emissions in check wwith each state, etc. :)
Weird question but do you think the gt and gt500 and gt350 headers all fit the same ?
Great contents
I suggest to do a video about weight reduction part like new bear brakes battrey and the wheels with details like how much weight brakes shaves off not only seats and delete back seats these new gt500 you can easily get power but it's to heavy if you can shave 200 lbs pound with brakes wheels battrey it will be a big improvement
We can do a brake video on a Mustang GT but I sure hope no one would put Baer brakes on this!!! That would be a sin IMO. That's more for a drag car setup and I don't think many are building GT500 drag cars. We will drag race them but most don't want to ruin what makes the car so special. And the braking is a big part of that.
You’re building a perfect complete package street GT500 Ken, definitely keep it up
Can you please give me the wheel studs specs you are using for your CF wheels?
Bruh ... I just got my whip and u about to put me back in Debt.. man that thang is nice
How much if any did the headers lower boost?
Problem with those short ram air filters is that they create no suction when driving. It just sucks up the air in the engine and some from outside. But no suction like the stock air system.
That's why I love the Corvette's air system. They usually have it right at front
The JLT and other still use the air inlet from the front grille. I haven’t personally experienced any difference in IAT’s after installing my JLT on my 2021 . But did shave 0.3tenths off my 60-130 times 😊
How are the Kooks headers holding up? any issues so far ?
Are those aftermarket seats? If so where can I get them?!
i dont care what people say, this sounds way better than a lexus LFA
Are these catless or with green cats? I have a gt500 and I’m trying to decide if I should go catless or green cats
Beast!
What else did the car have done before headers? Ik this cars not 850whp stock lol
Edit: is it just CAI+E85?
Badass Ken
At what rwhp level does the dct start needing clutches
What color code is your gt500? Thanks
If you're pulling the head unit to port it, drop that KB intercooler in there. Even at stock boost, it helps.
I have and recommend the Whipple but it's not installed yet. I don't think KB has one out for this yet. It would make sense to do it all at once but I'm doing one thing at a time to help everyone see this progress step by step
@@PalmBeachDyno I meant the Whipple. Too many brand names in my noggin.
Howd you get the carbon wheels
I need those Seats!!!
So the gt500 doesn’t have a maf?
What color is the blue mustang mustang
What fuel was he running?
Ken don't you get fumed out in that shop with no exhaust vents hooked up on the car during these dyno pulls?
Holy shit so this is the future. Flying cars these days is what these factories are putting out
this is stock seats ?
What seats are those?!?!
Any idea on the cost per HP increase? Thank you great video.
What color is that?
The way the engine shakes when you let off is violent. Are you running pump fuel at that level?
No, just larger injectors are needed at this level. We have made 950 without any other changes. Above that we recommend a fuel pump booster
Sweet
Get it ported by jokerz. They’re the main ones taking out the most material.
We need more power ken
I’m here to speculate who he is gonna use to port the blower. My instinct says Kong but I wouldn’t be surprised if he didn’t go elsewhere just throw everyone off.
I hope you are able to do throttlebody only, then with ported supercharger. Would be interesting to see any gains eith just throttlebody.
Mainly because it seems when people do the intake they typically do the throttlebody as well.
We already did that. There were zero gains as expected. The stock flange is restrictive so that needs to be opened up for the throttle body to help. We will mention that in the porting video.
@@PalmBeachDyno should have expected you already tried it. Keep up the good work
Guy walked in in the beginning and was like "ah sh*t it happenin" *plugs ears*
Headers are great but not worth the money to buy and have installed. Almost 3 grand for my roush mustang installed and probably only getting maybe up to 30 more hp.
Man I miss Palm Beach... I'll be back, no Arnold.
What's the entire exhaust after LTs?
Kooks 3" mid pipe to the stock catback
Who said crossplane V8's couldn't rev high?
Cool...
How much louder was it after the headers?
A lot louder. I just installed a set with Corsa Extreme cat back with a double h pipe. Normal mode is almost equivalent to having stock manifolds and cats with the corsa extreme cat back in track mode. Track mode now becomes headers with 3” pipe. Quote mode gets you out of your neighborhood but it’s definitely much louder and much deeper.
How does the new dual clutch seem to be holding up at these higher HP/TQ numbers? Have there been any transmission failures yet?
I haven't heard of any failures on a modified vehicle. We have multiple cars above 900 wheel with no issues so far. I'm sure we will need a clutch upgrade at some point
AS TORQUE AND HP CHANGES IN GEARS AND RPM. WHY NOT DYNO TEST GOING THRU ALL THE GEARS AS YOU WOULD DRAG RACING. I THINK IT WOULD BE ADVANTAGEOUS TO DO SO. IT WOULD BE INTERESTING TO SEE THE TORQUE NUMBER IN FIRST THRU 7TH, AND HP AS WELL. AS WE KNOW LOWER GEARS GIVES YOU MORE ASPHALT TORQUE. GOT IT!!!.
859 is closer to 850 than 900....ijs??
👍🔥🔥🔥🔥🔥
Sounds soooooo good and Velocity blue is 🤪🤪🍻🍺🍻🍺🍻🍺👌👍👌👍!
Thanks!
You blokes buzzing this thing to 8500, jesuss, would of thought the rods would snap. Good gains though.
What wheels are those?
The stock ones
Joao Salvattore they just look like fiber ones and I thought the car was a base gt500
OLOLOLOLOL Ny-lok nuts on the collectors?! please tell me those aren't...
B U T FULL. Should try Boostane (1 ounce per gallon). Made ''free'' power on the dyno.
Is it for sale?🙏🏽
Did anyone else notice it sounds like a coyote with longtubes and x pipe
5.2 is pretty much a bigger coyote the voodoo 5.2 is the only different one the 5.2XS and 5.2 predator are the coyotes brothers
I helped start up a shop in wpb then got let go because of politics. I am a customer service specialist. I hope to see you at cars and am rooting 4 you to always beat my former shop.spiteful and a little petty , but soo what.
Real American Muscles
Speed density?
Welcome back 1988...
I always think the same thing when I hear that lol
20wheel for $2500 not worth it. Stock headers are fine.
Headers are the most overpriced car part, 2500 for like 200 of material
Headers are everything to make Mustangs sound evil. Air in air out
Awesome stuff as usual Ken! I shared this on the GT500 forum: www.fordgt500.com/threads/2020-gt500-long-tube-headers-test-video.193193/
Thank You!
Till they have hub wheel dyno then i will believe the HP figuers, like this upload cheers :) th-cam.com/video/OgPcyafudfU/w-d-xo.html
But please understand, this is going back to the first release of the mustang and Harrop is world renowned for performance upgrades from AMG BMW and the Oe FORD and holden or chevy performance upgrades, cheers :)
FIRST COMMENT
Waste
I miss my Mustang! Wish I hadn't sold it to Geico after meeting a few crape myrtles. RIP
What color is this?
Velocity Blue
@@PalmBeachDyno wow, i thought I didn't like velocity blue.
This looks so much deeper than most of the ones I've seen before
