Need turbo size help - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

So I'm selling my twin turbo kit and going big single.
The engine is a 6.0 iron stock bore, stock stroke, ls3 heads, sheet metal intake. Going to be on e85 and making 1000whp.
Was looking at the s475 with 1.32ar but not sure if that's a good size. Car is also going auto with a th400 but unsure of the stall size yet.

If you were at 1000, im assuming going to a big single you will be looking for gains. I have seen S480 do mid 1100's on a 6.0, although you may have to go T6 frame. S475 might be close to where you were at with twins, alot depends on the housing you use. For PTE 88/47 is a 4" dump on a T4 flange, someone on here did 900+ wheel recently on a stock block ls3.

I went with the cast wheel s480 T-6 96mm 1.1ar and v2 race cover from lil John’s Motorsport. On my bone stock l99 I start building boost at 1900rpm. For me I wouldn’t want the s475 or the t4. I’m very happy with what I got. This turbo on a 6.0 with lower compression will take a little longer to spool but not much.

Your twins won't support 1000rwhp, or is there a different reason for going to big single?
