hello fellas ive just been looking for the answer to this without any luck all the threads ive read they just seem to dodge the question so does any1 know what benefits there are with running either the 58 or 76mm turbos?

thanks

 

im guessing that the 58mm will be a better punch but the 76mm will flow more air allowing better top end power? is there a point where the 58mm will become choked and the 76mm will be needed?

 

According to JGM he's found very little difference. I also assumed that 76mm would work better as it flows more air but apparently very little in it

 

I was thinking of having my 58mm inlet changed to a 76mm as I thought bigger would be better but Mark from Lateral advised against it . Apparently the 58mm is less prone to surge and doesn't really flow any less .

 

thanks for the reply fellas so do we think a 76mm turbo will have no gain over a 58mm at around 500bhp?
