The catch can and pcv plate are great for track, but if you drive a significant amount of time on street, they cause a lot of crank pressure, which is going to lead to gaskets and seals leaking. Many of us have learned this the hard way. BL version of pcv with a CC is usually pretty effective, but full mk8 retrofit is better. Keep the TIP stock. It greatly affects crack pressure.
The exhaust side of the catch can or oil separator shd be connected to the inlet side of the turbo to provide a constant vacuum. Once that's done properly, it shdn't lead to seals leaking isn't it?
@@powerst33r not always. Depending on the engine and intake setup, you might have positive pressure at idle and low throttle, or until you hit higher rpm. It's not as simple as that. Testing that has been done on the stock mk 7 TIP has shown the shape of the TIP and the location the PCV line connects to allows for a vacuum. If you change the TIP, you lose the vacuum on the PCV. The Mk 8 retrofit creates a venturi at the PCV outlet, allowing you to use an aftermarket TIP without affecting PCV function.
Good stuff! Sport dampers were a big miss here while you had it apart for springs...Koni or Bilstein dampers have seen a drop in lap time over the stockers.
As an original owner of a 2017 GTI, and has modded it quite a bit in just about every category, if I just wanted a fast track GTI, this is what I would do first: 1. Suspension (Dampers and lowering springs or coilovers + RSB) 2. Tires 3. Wheels 4. Brakes 5. OBD11 These five things will make the GTI handle very well on a track, and get you much better lap times. If you want to add power into it, here is what else I would do: 6. Software tune 7. DSG tune (if DSG) 8. DP 9. Intercooler This will net you a quick car. There is always more room to grow from here but these will transform the GTI into a street and track weapon.
Would you recommend adding the front sway bar if you already have a 24mm rear? Just wondering if its worth it to reduce body roll and improve turn in. Dont want to add springs that lower the car. Thanks

can some one explain about the ESC off options in the obd11 what the different in each one and what recommended for track use ? and is it off permanently or just change it when you press the button and have still the stock esc for daily ?
How do you deal with the DSG auto upshift? Even with my 034 trans tune the damn thing will auto shift in manual. 034 told me it is a built in dsg safety feature they won’t turn off, but it is so annoying! I’ll drop two gears coming out of a corner because the car will auto “safety” up shift while I’m mid manual shift. Very annoying. 2018 autobahn.
Oh yeah I’m in S, manual, and traction fully off via obd11, all the good stuff. It will shift at 6500-6900 automatically regardless of mode . 034 confirmed that is normal behavior in manual mode due to the auto shift safety feature they kept on with the factory tcu. It is very frustrating
@@Grassrootsmotorsports I just heard back from 034 today. They have adjusted the auto shift point to 7400 RPM on a new update just posted, which should fix this issue! Very exciting.
@@LoveLikeaHurricaneno. Redline is 7100 - so it will hit redline first. If it can’t get past 7100 rpm, it won’t hit 7400, and therefore won’t auto shift.
Did you feel the need to intstall an aftermarket oil cooler? Im running a stage 3 GTI and after a few pulls the oil gets pretty hot. I'm planning on tracking it in the future and am wondering if I can just get away with a catch can system.
It sounds like they went crazy, but they actually chose wisely. They avoided exhaust, calipers and coilovers. And the DSG allowed them to avoid upgrading clutch and flywheel. That alone saves thousands. The wheel/ tire combo was probably the most expensive addition.
Do you have a video on how to install the catch can? Had it for a while and did not route the drain back to the turbo due to it seeming like a daunting task and not to much documentation on how to do it.
@@jamaisvu2664 I have total respect for the CTR, I’ve just never been a fan of how I fit in them or the interiors of a lot of Hondas. But the CTR has become the benchmark that a lot of channels are comparing their GTIs to.
The only thing I would change it was the front roll bar. You should installed a lower camber plate instead, it will give you a up to -4 degree. Nice job anyway..
The MK8 is a lot quicker. Basically, in stock form, the MK8 is just as quick as a Stage 1 tuned MK7/7.5. A Stage 2 stock turbo MK8 is as quick as an IS38 (Golf R turbo) upgrade on the MK7/7.5
@@davothegreat9990yes way. Matter of fact, it really just comes down to the driver. I was at SEMA two years ago, and they had an auto cross track there. There was a brand new CTR racing on it, and it was in last place against a lot of other cars. The CTR is only as good as its driver, and isn’t really anything special when compared to modified cars.
@JacesOwnWorld yes a good driver can make even the lowest of cars look good but the fact of the matter is that the type r is overall a better performance car than a golf in every way.
Love the way you kept retesting after each mod.

is the MK8 PCV system not prone to the oil burn issue on track?
@@powerst33ryes, but when you're out of boost, you'll get positive crankcase pressure
@@jameshaulenbeek5931 The turbo inlet is always a vacuum as long as the engine is running

Just goes to show you that lowering your laptime is not about power, it's about pretty much everything else!
Except they did add 80hp and 100 tq.
Would be neat to keep a running 'leader board' of lap times to compare
Good stuff! Sport dampers were a big miss here while you had it apart for springs...Koni or Bilstein dampers have seen a drop in lap time over the stockers.

8. DP
9. Intercooler
This will net you a quick car. There is always more room to grow from here but these will transform the GTI into a street and track weapon.
thing with intercooler+tune is that will block your radiator and water temp will skyrocket...
What's DP? Thanks by the way!
@@johngreen8693 downpipe
@@zuluagaco Thanks!!
Code the VAQ diff to increased traction, this will essentially make the LSD work more/better :)

You should put it back in the vending machine when you are done, some lucky buyer would freak out!
You can drive to work on 200 TW! Just saying

Yes, it is at the FIRM.
You could haver skipped the rotors and just put proper pads on. Pads mean more than anything else in the brake system compared to stock.

Title should say “A 034 advert”
