Bison - T350 Turbine

[Jerryl]

Noticed you have referenced this wheel in a few posts lately.
I know this wheel is in a 6152 and have seen it do 126 MPH.

Can you share how this T350 turbine compares to say a P-Trim and/or others?
Just trying to understand.

Here are the 76 p trim and the t350 stage 5. Both have slight damage to them but are for illustration and general comparison only.

The 76 p trim is a heavier 11 blade turbine with a taller center to tip dimension and has less pitch on the blades. The T350 is 10 blades with a heavier pitch and is considerably lighter. It is the beginning of the Garrett GT stuff. Almost every high performance turbine designed in the last few years follows the blade style of the T350 now with more curve on the blade. Both will support a lot of power on a single turbo application on a turbo regal. The only one i know of that posts on here that has possibly maximized the 76 p trim is John Crawford. He went 139+ at full weight. The T350 has been 126+ but is easily capable of more. I havent run one out but i dont see it being a problem till you are well over 130mph in the quarter. For its size and weight the t350 flows a lot. Tmk the T350 hasnt been used on an engine that will really show its potential. I can see the 6152 (GT35R compressor wheel/ T350) running 134-135 on a serious engine if it were run for all its worth. Both need a good converter to work well. A 2800 9.5" with a small Garrett housing is ok with these when they are coupled with small compressor wheels like the 60-1. The p trim really needs a 3000-3200@zero boost/vacuum to work well though. If heavy compressor wheels are used the stall requirement goes up. If someone has bettered the mentioned numbers post up your combos.

bison i have seen the 6152 go 130mph on a very good motor, the ex housing was a 4 bolt.

What else did it have?

As always, you have been a great help!

bison it had slicks,gears,lots of things were taken out to make it light,mystery cam,ported heads,raised compression,116 octane with a hot tune i guess the question should be what didnt it have

The cam lobes, gearing, abd converter coupling ability info would be useful.

i drove the car and the converter felt very loose it was a 9 nonlocker from protorque,sorry but i dont have any other specifics of the car.
