GAS FLOWED HEADS?

<< < (2/2)

ferret:
Well ive already got the big intercooler,tweeked pump,boost turned up,straight through exhaust so do you thing gas flowing the head would be worth it ang how much power increase is there.
also changing the cam ,benefits and disadvantages?

extreme90:
a gow flowed head didnt increase power on my 90
just smoothed out the power delivery
also, i noticed the turbo comes in even earlier aswel
IMO
i wont have another, not worth the 400 notes 2bh
had more fun aswel before with the sudden kick at 1400rpm :lol:

ferret:
gas flowing is just polishing inside ports etc or am i wrong.

extreme90:
the ports were opend up on mine
had to trim the inlet and zaust manifolds
i was going to have the valve guides cut down aswel as there a nice big obstruction
but gain vs reliabilty/life span i decided against
