Cylinder Head

[BigStan]

A gasflowed and ported cylinder head for a GTE, how much of a difference does it make ?

[Adam]

Probably about 10-15%

to be honest i wouldnt quite quote a 10 - 15% increase with just a bit of porting. Your probably gonna only get a few bhp over standard.

blydenstein quotes 8-10% on a stage 1 head which is simply porting iirc

he quotes 10-12% on A pack and 12-14 on B pack as well im sure
