MK7 GTI w/ IS38 APR Tuned Dyno on Pump Gas
Вставка
- Опубліковано 21 жов 2024
- Full bolt on 15' GTI with IS38 turbo on pump 93oct. SAE corrected 371.35WHP/381.31WTQ. STD correction factor reads 380.56WHP/390.77WTQ.
The numbers are pretty good, but still had more left in it with better fuel and ideal conditions. You can see they used only one small fan that was far from the front of the car and pulls were done directly after driving through 2hrs of traffic, so IATs were well north of 100*F during the pulls.
Hello,RjRacing
Did you make Waste-Gate Adaptation on your IS38 as APR recommends??
what kind of wheels are those? Specs?
Which tune and what are your mods? Good numbers ;)
have apr stage 2 and downpipe in my gti mk7. do u recommend the is38 from your experience so far? really interested in this hardware
Congrats! That is a nice upgrade over the APR Stage 2. How does it feel when you get on it compared to stage 2? Does APR supply a complete kit for this? Is the IS38 water cooled and does the stock water cooling pump work with it?
+Rad Fox IS38 is a bolt on turbo, all the coolant and oil lines bolt right up. It feels great, super wide power band... you can see it doesn't fall under 300HP or TQ throughout the entire pull. The car just screams up top now too, but it doesnt have that massive torque punch the IS20 did early in the power band that died in the upper RPMS. Check out the video I posted against the guy with the stg2 who was cool enough to run me.
+RjRacing Wow, you pulled on him like crazy! Amazing!
That air spinning sound scares me. Can someone tell me what that is? Is it the turbo under strain? I just want to know because I haven't heard it on turbo cars from other brands.
That's compressor surge. Basically only happens prior to 3k rpm, before valve cam profile switches over to accept more air(VW version of VTEC), turbo is trying to cram air into the engine where engine can't take anymore, so air surges back out to intake against the spin of compressor. This is really bad for turbo shaft and bearings. The sound you are probably looking for is those swooshing squirrel sound from JDM cars when they lift off, that is perfectly safe as wastegate opened and turbine isnt spinning the blades anymore.
@@brianchen3964 interesting that the VTEC kicks in at 3000. How do you know that? I seem to have compressor surge on my stage 2 car and like you've said, I landed on it not happening above 3k but happening below 3k....
hello man!!! your car is sick!!! i would like to know if u have apr stage 2 file or apr is38 file....thanks for your time!!
What are full mods on car? DSG or MT? Upgraded clutch? I too, own a 15' PP GTI
+Edward Cendejas full details seen here.... forums.vwvortex.com/showthread.php?7116366-RjRacing-s-GTI-PP-Build-Thread
How much are you dropped on the Bilstein b16 coilovers?
What is your front ground clearance with the drop and the maxton front lip?
About 1.75", 3/4 of the way down on the adjustment Bilstein offers. I have never measured the lips clearance, but it's just enough to get around on public roads without catching on everything. It's nice that it's raw plastic too, so when it does scrape it doesn't do anything.

So I just installed 245/40/18 tires (BFGoodrich G-Force Comp-2 A/S) on my 18x8.5 ET45 wheels. I am rubbing a little on the fender liner in the rear on the gas side ever so slightly with my 5mm spacer installed. I don't think this is a big deal though.
I am worried though because I have Bilstein b16 coilovers (PSS10) coming and even with their standard 30mm drop I feel like I may rub in the front and rear with these tires because they stick out a little further than the wheel. Am I going to need a crazy alignment or anything or will the tires tuck in a little from the drop? I know you modified your fenders because of the front brakes but did you need to modify anything before then with these tires and the initial 30mm drop with the VWR springs? Also, the coilovers state on the Bilstein website that they offer lowering of 15-35mm. However, you are lower than that which makes me feel like it is actually 30-50mm of drop.
Wish i could get those numbers, my Apr is38 91 octane is just pushing 300 on a mustang dyno.. our gas here is shit
Is this 93 octane gas or e85
Are you on coil overs or springs
Complete street! Had a dyno done there before too. Just picked up a 16 gti with pp - would love to meet up and check this thing out!
+Greg Manning-Smith Nice, Congrats! Absolutely man, hit me up if you know of any events going on.
Would you recommend going straight from bone stock to is38 or would you go stage 2 first? Thanks for the help bro... Just picked my mk7 up about 2 weeks ago
you should get a tune. I would get the is38 tune from APR
I finally pony up for the R and the GTI is this nasty with only the R turbo on it. I want to see that thing run the 1320 on slicks. Hopefully not in the lane next to me. Haha.
+Meat Amigo It would take slicks to keep up with you from a dig lol. Thanks man, I can't run slicks bc of my BBK... not really a fan of 1/4mile racing either.
well nice tho, we got 382whp ,382tq
wtf why am i getting such low numbers on my is38 just pushing 300HP on my PP GTI stage 2+ APR wont even respond to me
Probably because you are running on Mustang Dyno? They output really low numbers
wow nice numbers! what other mods you have on the car?
+Victor Quezada Pretty much full bolt-ons. Its easier to list a link than the mods lol... forums.vwvortex.com/showthread.php?7116366-RjRacing-s-GTI-PP-Build-Thread
+RjRacing oooh thats you! nice set up man. You think the stock internals will hold up good with that power?
+Victor Quezada - Oh yeah, no problem. GTI and R use basically the same internals and APR has already crossed 500WHP with them without an issue. Another guy in UK is almost at 600WHP on stock internals too. I'm not saying going that high is super safe, but the power limits of this motor seems to have yet to be discovered so far.
I just asked this very question about stock internals on your other video. Your reply was 8 months ago. How is the car holding up now? Any issues with the power? I read people having issues with turbo's blowing on the 2015 GTI models.
methanol ?
Nope, just street gas
does this have APR's mew intercooler?
+omar elkhazendar Nope, Forge Twintercooler. I think the APR unit would likely make even more power too, but I probably won't end up going that route unless I come across one for cheap.
Thats fair enough man thanks for posting such an amazing video I really appriciate it even though I dont own a GTI im considering one, if you wouldnt mind sharing what was the cost of the is38 turbo itself and how does the car feel now when it pulls and does it put the power down well? Also any 0-60 or could you make a 0-60 video Thanks again!!!
+omar elkhazendar The IS38 cost me $1,300 from VW and it requires a tune too (another $995 retail from APR). The car is ridiculously quick for a little FWD hatch, yet it still manages 35MPG on the HWY. No 0-60 times recorded, I am back on all season tires now so traction can be an issue from a stop. From a roll this car is a beast though, I have no problem keeping up with most 450-550HP cars (like stock-ish C6&C7 Vette's, CTS-V's, SRT8's) due to its light weight and quick shifting DSG trans.
+RjRacing so you got the turbo straight up from vw dealer ? And i see you on take 2 apr even with the new turbo , I thought you had to get stage 3 to see HP GAIN.
RjRacing dsg tune?
stage 3?
+Reesecup1200 Nope, just the S3/R turbo and tune. I think companies are calling it a stage 2.5 for the GTI.
Im apr stage 2 right now , to do that turbo swap with minimum requirement is $1200 for the turbo , $800 for the intercooler ,$700 dsg tune, $700 ecu tune for is38 turbo , $100 spark plugs, plus installation lol I'm good , stage 2 as it is with michelin pilot super sport already cost me 3k plus but shit everything i see your dyne 390whp im like it might me worthy lol
+dominicancash Hate and troll much? lol. I do all my own work (aka no cost) and have some sponsors. Turbo cost me $900, Forge IC was $450, USP DP was $400, plugs cost $19 and then the APR tunes which I'm not going to discuss what I paid for. Please take your hate game elsewhere loser.
+RjRacing hate game nigga i have a better car thank you do cuz mine is 2016 autobahn and is fully loaded with the driver assistance pack yours is just an se , i have spent more money that you on my car based on what u telling me ? Only my Michelin pilot super sport were $1000 plus apr stage 2 with usp downpipe , this nigga acting like i want your car like yours nigga i have a better car , my argument is valid is you do all the work a nice shop like i do is gonna be the amount i said , luck it you that u can do your own crappy job.
+RjRacing u just dont wanna be that dumb ass who spent 10k on a gti instead of getting a golf r , u have sponsor lol like u take a gti to the track , if WOLF doesn't have sponsor imagine YOU.
+dominicancash LMAO, you're telling me I should have bought an R when you're the one that spent almost $35K for your GTI hahah. You're a clown and the way you talk proves it. I own 6 cars, this is just a daily driver for me and one of my slowest cars too. You clearly don't know me or you wouldn't be making these moronic comments. See you in the rearview.
+RjRacing sorry didn't know u leave the audi r8 and mclaren p1 for the weekends , this nigga. The rich nigga that drives a GTI
Shittttt based on the engine alone u have spent close to 10k
+dominicancash Not sure what you are talking about... but I only spent about $3k on engine mods.
