Hi there,

where did you get the work done on the head? how much?
I would say 170/180 BHP with a good live mapping.

I'd agree with the lower to middle of that figure with those cams, 185bhp is what you'd expect to see with bigger inlet valves & more aggressive cams like catcams 213's or Piper 285's

I did the porting myself.

Lets hope I didn't opened it too much.

The exhaust ports passed from 33mm to 40mm.

Paddy no vernier pulleys...

Standard ones...

I know you're against that.

hi and greetings from finland!

one viable alternative for adjustable pulley is renault 1.5dci pulleys. im fitting those in my second megane f7r-710 engine build at the moment. maybe i add later some photos of this invention :) just join your forum,

I would like to see that, because maybe the solution for my problem. Or maybe someone else could say what I need to do do fit this on ours cams?
