I am buying a Precision SC61.Using a .63 exhaust housing.The turbo will be used on a 2.0l 16V engine with a compression of 9.0:1. I wanna make over 500WHP .

Can anyone tell me whats the difference between the following SC61 combinations.

SC61 T3/T4 -6
Compressor: Wheel Inducer: 2.416" Wheel Exducer: 3.227" Wheel Trim: 56 Inlet Size: 3" Outlet Size: 2"
Turbine: Wheel Style: T04 Wheel Inducer: 2.920" Wheel Exducer: 2.542" Wheel Trim: 76 A/R: .63
Max HP: 680

SC61 T3/T4 -4
Compressor: Wheel Inducer: 2.416" Wheel Exducer: 3.227" Wheel Trim: 56 Inlet Size: 3" Outlet Size: 2"
Turbine: Wheel Style: T04 Wheel Inducer: 2.920" Wheel Exducer: 2.420" Wheel Trim: 69 A/R: .63
Max HP: 680


SC61 T3/T4 -2
Compressor: Wheel Inducer: 2.416" Wheel Exducer: 3.227" Wheel Trim: 56 Inlet Size: 3" Outlet Size: 2"
Turbine: Wheel Style: T350 Wheel Inducer: 2.920" Wheel Exducer: 2.420" Wheel Trim: 76 A/R: .63

Well the first two are straight T4's obviously. IMO if you wanna go for over 500whp a T350 SC61 would be good enough.

 

Hey Mark,

ok let me give you the full picture.I am busy with a 2.0l 20v vw motor and a 2.0l 16v engine.Both running 9.0:1 compresion.
both motors will be reved to 8200rpm.

1.Which wheel will make more power...???

2.Which wheel will make the turbo come into boost sooner..?

thanks man.

1. T04 76 trim (P-trim)
2. T350

as per Rod from Precision:

The T350 wheel rates the SC61 @ ~620hp
The T04 69 trim brings that up to ~650hp
And the T04 76 trim brings that up to ~680hp

i think u'd be fine with the T350 one honestly. The T04 wheels will work and I doubt it would be THAT laggy on a 2.0L but you could easily reach your goals with the T350

 

Thanks for your input.

Well this is what we are going with. We are going to use a SC61 with AR70 E compressor housing and a .63 exhaust side with a t350 76 trim wheel for a 2.0l 16v engine. And a SC61 with S compressor housing and a .63 exhaust with T04 76 trim wheel for a 2.0l 20v engine.

So be interesting to see what numbers we get.

the T04E housing is a .60 A/R, the T04S housing is .70 a/r and it's like ~$100 upgrade to go to the S housing.

 

Right you are.Got a bit mixed up there.
