I'm basically looking for some info on how different size turbine wheels affect Turbo performance. I've been looking at s400 turbos and there's so many different turbine wheels available. 83mm 87mm 92mm 96mm. Any info would be great guys. Thanks
This would be for a dedicated pulling truck so would bigger be better?
whats done to your fuel system
Good Info. here guys!:thumb: I understand having to have a loose convertor to light a big turbo but what do ya'll mean when you say stay on top of it? Are you talking about like when the truck shifts and rpm's drop lower then the turbo would run back into a lag situation? So if you where sledpulling and the truck shifted and rpm's dropped you wouldn't be able to get the turbo back lit again?
I think it would be easier to spool for sure but it shouldnt be that hard to spool as it is. What do you have for trans tuning?
