Default Twin scroll GTX3576 b18C

Anyone ever went this route before ? If my semi educated guess is right it should work really well and give a massive powerband but if anyone has done it before dyno data would be nice to have.

Manifold is Finished and on its way to me hoping to have the build finished early next year.

Type R cams, 9.0:1 compression, Gen 2 gtx3576 with twin scroll 0.82 housing is the basic spec.

Any input would be appreciated

thanks

Jed

That turbo will do really well IMO. Just need to have the right package to back it up.

My STC interceptor setup was similar:

Interceptor (This turbo matches best as an inbetween between the GTX3576R and the GTX3582R)
Type R Cams

~10.1 compression
84mm x 89
PerformerX Intake
Miniram Exhaust
E85
Around 30 psi





Why so low compression?

Going low compression because I will be running UK pump fuel and dont want to run water meth injection.

Not really wanting anymore than 500 at the flywheel but will depend how my well my 215 tyres cope with boost by gear/rpm.

Seems like a big turbo for that power. These are 75 lb/min turbos

Yeah its with a mamba turbine housing think the warranty is void if you go above 1.5 bar with them but hoping it should do good power at even at1 bar.

You do realise that if it breakes theyll say you pushed it at 2 bar and you cant prove them wrong right?
