SR20DET 3071r Dyno

[derass]

nice build and numbers! personally,i would think a 3076 would be a better choice for an all out t3 setup...if you wanted a 71mm compressor you could have stayed bottom mount. and i doubt a 3071 will spool faster than a 2871. this is because the gt30 .63 turbine is slightly larger than a GT28 .86 and would therefore spool slower. that dyno sheet shows the 3071 coming up on 15psi at 5500 RPM

if you have ever been in 3071 setup you would know thats a huge misconception

Thanks man. Like i said, the boost plot wasnt very accurate. On the street I have 17psi well before 4000 rpms with the 3071r. And my 2871r with a equal length silkroad manifold would hit 18-19 psi around 4k. Just because on paper it looks like the 3071r should spool slower doesn't mean it actually will. And remember, this is only for my particular setup. I'm sure other people will have different results.
