S475 drive pressure

[superstroker99]

Im running 350/200's, turbo is a S475 with a 2.6 cover. Turbine side is a T4 1.32 a/r with the 96mm wheel. Anyone have a idea what I should be seeing on my drive pressure. Thing lites pretty well but when chained to the sled when I go to 3rd gear it falls on its face. Got to data log it last sat. Shifted out of 2nd right at 4000 rpms boost was about 58 but never saw more than 40 psi on my drive pressure. So when i went to 3rd it just wouldnt stay up. I have checked for exhaust leaks on the manifolds and up pipes cant find anything.

Drop to a 1.10 t6 or a 1.25 t4. The 1.32 is too large if you cant go down the track at 4k +

Converter locked or unlocked?

locked.

Yeah no point in 1.32a/r unless you have a turbine in front of it.. the turbine is gonna be pretty salty though to get a 1.10 milled out to 96mm

:whs: I have the 1.10 with slightly smaller injectors and they're a perferct match.

But wouldn't that 1.10 be kinda thin once its cut to 96mm? I have thought about putting a mild shot of nitrous on it. i have also found a set of 450/400's for sale

There is no milling involved to get a 1.10 housing, its a stock option for a 96 wheel from borg warner.

Well, learn something new everyday

You could also go to a 1.15
