now show me that exact setup w/ just your normal t3/t4. i bet they both make the same power. which is my point, precision turbos arent proven to make more power compared to your run of the mill t3/t4

without running the exact same setup minus the turbo change it would be impossible to do this experiment and get accurate results

 

start another thread for that debate, it detracts from the debate of this thread, the appropriateness for the sc61 on LS motors.

thx

What is a run of the mill t3/t4 that is similar to the SC61? Find one please..

 

SC61 has a a/r of .63 right? compare it to a .63/.60 T3/t04e and i bet they make the same amount of power under 350whp

Do you actually know what differentiates the sc61 from the standard garrett t3/to4e's or are you just trying to be anti-sc61? I ran a t3/to4e 60 trim .63ar with my old setup. It made 307@14psi, im willing to bet @ 14 psi my sc61 will make more than that.

By this I mean you are paying $700 for a turbo that isn't efficient for under 300whp. You will lose midrange and have a slower spool up, but you will have the sc61 BLING factor. A smaller t3/t4e is much more suitable for under 350whp as it is much more efficient at lower flow levels and thus produces much more midrange power. A broad powerband is obviously ideal, and having an LS motor basically essential or you will drop to low power levels when shifting.</TD></TR></TABLE>

It isn't really "less" though. I see it as an investment. I had plans to do things like built block/vtec head/standalone/ect but got a good deal on a used sc61 with .70 S compcover (+$100 option) so I went for it. When I talked to art he said that it starts being efficient at about 8 psi so it would work for now AND I wouldn't have to upgrade it come time I want more power. Who dosen't eventually . But yeah if you don't ever plan on upgrading I agree a t3/t04 would be much more suitable. And honestly it wasn't THAT bad, it would spool 10 pounds by 4800ish and pull like a train to 7k, I didn't mind it at all.

 

well if you eventually plan on making 400whp+ then obviously its a good choice

that goes directly inline with what I said. However using it for less power is not a good idea.
