If you had blown 5 turbos in 3 years and had to rebuild the engine every time, lunching bores and destroying heads, I think I know where I'd stick that envelope if he pushed it.
The aim of this was purely to give Noel a fast car. He continued to push the 35R til it's absolute breaking point. Every time one would blow, another would go on, then blow.
We moved to this turbo because we know what it can do and hopefully it will mean he can actually go out and race the car instead of waiting for me to have time to build him another engine.
