I'm going to be building my motor (parts in the mail) hopefully looking to make 350-400WHP, my SC50 has a .48 turbine.. Is this going to slow me down? I dont want to stress about having too small of a turbine for my set up... My LS redline might be around 7500 RPMs because i'm going to get ls turbo cams also, thanks for any input

 

not as bad as my sc44

 

Try downloading the compressor map for that turbo and that should help you understand the power level of that turbo. Btw, what's your set-up, I'm almost done with my ls turbo?

 

The .48 A/R will have a faster spool and should still be capable of around 400whp. With a 7500rpm redline, it was a good choice.

I'm using the same turbo in my setup.

Im not sure, but Ive talked to Arturbo and Boosted Hybrid, and both told me to go with the larger .63 turbine housing for my stock LS.

 

I have a .48 housing on my t3/60-1. Boost starts to build at 3k and full boost by 4800rpm.
