72bb S-trim?

[chasmat2316]

anyone have feedback on this turbo?

The Turbonectis one? I run a Turbonectics one and it spools faster than my 70 q non bb. turbo. I have not put it above 20 psi so I can not tell you that is makes more power. At 18 psi I run the same mph as the old turbo.

What boost did you run with the old turbo? What mph?

 

[boostingbuick]

18 lbs on 93 with both and ran 126 with both.

Damn that mph is impressive for 18 lbs of boost and 93!


Is that just straight 93 and no alchy?

Here are a few pics of my GTK-850 72mm, it has a .85 precision housing with a S-trim exhaust wheel. I'll let you know how it works in a couple weeks :biggrin:

is a s-trim just the new version of p-trim or is it actually larger than the q?

 

[Royal-T-Ltd]

i think its larger than the "Q"

it basically replaces the Q trim wheel..

 

[DR BOOST]

ther reason i was asking is because the part number of the exhaust housing on the posted pic of the turbo is for a p-trim(76) wheel. the qtrim part number would be 80.

The exhaust wheel measures out to 2.694 on the inducer and 3.111 on the exducer or is it the other way around I think the housing was cut to fit the bigger wheel, the new HPQ wheel is almost identical in size.

Doc, like ILUVBOOST said...... We use the P trim housing and machine it out to fit the new S-68 wheel.

Are all the 70 series exhaust housings the same dimensions in p trims and q trims? just the wheel different?

externally the same, the internal dimensions for the wheel must be machined to fit the different turbine wheels.
