I ran a s472 with 1.10 83mm wheel and loved it...22psi was great spool really fast....yes even when it was a 6 speed. At lower boost levels 9-12psi it wasn't really all that good...18-22 was at its happy place. When I switched it to auto (4l80) it really woke up even at 12psi. With the auto at 22psi in 3rd gear 3.42 gear it would spool 2100rpm 1 psi and 22psi was about 4200. Just had a eBay manual boost controller, but once it got to about 10-12psi it really started to spool up hard. Hope this answers your question.

Yeah you should spool it fine. the 75mm wheel has 1 less blade and will spool a little quicker than the 7 blade 80mm comp wheel

Thanks I'm going T6 because I'm on the budget side of things, and I'm building the kit so why not save the $200 extra they charge for the T4.

T6 housing right? This is my first Turbo build and I want something fun for the street. Was yours daily driven

Yes t6 and driven daily...drove it 500miles round trip to oc cruzin put 11,000 miles on it from April to now lol. Only problem was the twin walbro 255's didn't like the 105 degree days we had in July lol

And also rolling brake spool to about 12-14 psi before it will burn the 315 nitto drags off at 65mph lol. When racing from a roll I could brake spool it in 2 second gear to any boost I could hook...about 8-10psi. And this was all done with the t56. The auto makes for much nicer and easier launches on the street and really picked up compared the t56 but both transmissions worked great with the 72

Thanks for helping out and giving me your feedback. One day ill go th400. For now the goal is to get it running, get the trans built by TDP and ride the 10bolt till it breaks. I'm anxious to know what boost really is. I've never been in a Turbo car.

You have any videos?

turbocamaro125

iTrader: (3)

No don't have any videos....I should have but never did...I have a gopro now so maybe some time ill get some vids up. I finally broke the 10 bolt it has 161k miles on it and 12k of it has been on turbo power so I think it did pretty good...it's not completely broke just makes a **** ton of noise lol

how would a t4 s475 with 83mm wheel 1.10 a/r spool with a t56 6.0?lets say 650ish rwhp?

turbocamaro125

iTrader: (3)

It will spool fast! I would get the 1.25 t4 housing for a 6.0

ok sweet im looking to be around that mark for now.nothing to crazy yet.im looking at forced inductions seems to be the place to go but i see there is 1.10 or 1.32 a/r

Yes Jose will hook you up...I've gotten 5 turbos from him. The t4 is gonna cost about 200 bucks more then the t6 version.

I was told not go to any bigger then a T4 s480 87mm turbine with my LQ9.
Mainly because it was a t56 car and it would not spool properly on the street. A T6 with a huge turbine wheel will be super laggy.

LilJohn

You were told wrong.

Id put 100 dollar bill on the T6 1.10 spoolig slightly faster than the T4 1.25.

If its got the correct evo for the ci and turbine it will spool fine unless you completely screw the pooch on the tuneup.

You start jerking timing out at 1 psi... theres not a turbo in the world that wont be laggy.

How would a T6 s475 83mm 1.10 spool on a 02 4.8, 03 ls6 cam installed on a 114 intake centerline? T56 and 3.42. In a 95 camaro. Or am I better off spending the $200 for the T4.

I had a 08 4.8 flat pistons, stock hgs, stock 799 heads ls9 cam and the same turbine size just a 72mm and t56 and 342 gears. It spooled good

If you are one of those guys that want to pull stomps...it's not gonna spool that fast with the t56....if you want a fun car that spools fast and has amazing mid to top end power get the t6 s475 1.10!

Well I guess that settles it for me. Its good to hear because I was getting tired of searching and coming up with unfinished answers. People swear by the search button but damn I wasted 1hr reading through crap. Thanks again man

I've never driven a Turbo car, I don't want to race from a dig since I have the 10bolt. I was thinking more along the lines of highway pulls. 40-140 MPH.

Man I wish I had some videos of me roll racing. At 12psi on my setup you will beat 600's from 50mph up....on 22psi like 30mph and up. Brake spool it first and you will take off. I always had 315 nittos I would ran them at 15psi when doing roll racing.
