STD sti headers
 

I want to no what is the max bhp anyone has acheived using STD sti headers and uppipe on a 2 litre newage, Not ported headers .(useing a bigger than STD turbo ).thanks Andy

Someone must have put a md 321 , 20g ,SC 42/46 on STD sti headers . What bhp did you get please ?

Why would you want to do that though? It would probably make a lot less power, and have a hard time breathing!

Ask Shaun, although his are ported he's running well over 500bhp.

But twinscroll aren't they?

ah yes, I didn't think of that.

I'd never use standard headers on a built engine.
