Title: Potential power gain?
Post by: MackyM on 15 January 2007, 18:48

I have a standard 16V producing an exactly standard 139 bhp. There is a local company with a good reputation that charges around 4-5 hundred for a head port/polish/gas flow thing. I was wondering typically what power advantage I could expect for the cash? Cheers.

(OK, not totally standard - it has a stainless exhaust and k&N filter. I'd expect 142-145 right now but the cam chain is a little stretched and needs replacing - this would be done too).

I'd be more inclined to say you'd get about 10bhp extra out of that mod alone. Chuck a 2ltr bottom end in the mix and then you'd have a big chunk of torque to go with it.

In a word - No   :tongue:


Besides, mine hasn't had any internal work other than a full rebuild to standard spec....get the head done on yours and then when you got the money get a 2.0 bottom end  :wink:

So you have 176 bhp with no internal work and a 1.8 bottom end? Couldn't I expect at least 160 then with gas flow, zorst and filter (and rolling road set-up)?? If so, I'm gonna do it. Your car must bloody fly by the way as after a rolling road session mine shifts very well with just 139..

I should have stated that mine's a standard 2.0 ABF running on K-Jet  :smiley: ...and compared to the old standard 1.8, yes, it flies  :grin:

Go for the head work and let us know what results you get. The best thing is that you have a figure to compare it to so you'll know exactly what you've gained.
