Way less failure points is why I prefer it. I've had too many things go wrong on track on my cars and ones I have supported. The less to go wrong, the better in my book. +200whp ain't going to help at all if you get a DNF.
I also get good looking clutches over others because it totally matters what they look like when you will never see them. I wonder what engine mounts Phil's wife's car has.
That is the biggest difference I noticed with XHP on track. All the "soft and lazy" shifts like that went away. I think it's part of the stability programming.
First off, avoid Vorshlag like the plague. They have no business doing anything with the MK5 Supra. Secondly, don't listen to any setup advice from them on the MK5 Supra. Thirdly, find anyone else.
If you are asking about OEM measurements, here you go:
Shhh. He watched a YouTube video that stated they did. He also made rubber circles and worked with Japanese companies, and all Japanese companies are the same, right?
I'd actually be interested to see what the guys with upgraded HPFP, Injectors and LPFP are getting away with for boost. Not much difference E60 to E80 tuning wise.
I'll never run that high of boost since I track the car.
