06 ST turbo build

[espacef1fan]

You are right it DOES have a bigger exhaust housing, but it will spool as quick if not quicker with a split scroll header....

Umm...The stock 2.3 Duratec Focus head flows like 300CFM on the intake and about 260 CFM on the exhaust. Not sure where this restriction you speak of is...

Yeah you're going to have to back that up somehow.......

Ported big valve head.......

Dosen't get into what pressures they used, what kind of clay radius, etc.

Anyways, for this guys power goal...

He would be best using a T3/T4 or soemthing of that nature ..The HY is just simply more turbo than you need for this.

If you are stuck ona holset and want good spool...

I vote HX35 and proper twinscroll header.



Also why the 9k rshared_pm goal?

I never said he had a restriction? I did give my personal proven experience with a holset and 100+ dyno pulls over a few years with different parts.

If his head flows 300cfm then thats great and all but if the rest of the system doesn't flow serious amounts of air it wouldn't matter. Bolt a 250cfm intake on a 300cfm head and the headflow with drop. This goes for every part of the system.
Should ad he seems to have a pretty good plan and seems like a decent guy. You on the other hand.
