Ported, polished and enlarged valve head..

[kevin_172]

What gains would I be looking at with the above 1mm enlarged valves?

 

[Fred@BTM]

a s**t load of cash for not a huge gain TBH

 

[kevin_172]

Only cost me 370 any rough idea?

 

[Fred@BTM]

i'll put it this way we had a head that was (in my opinion) excellent, nigh on £600 to have done, cars with similar work (stock bottom ends, we were running a chunk more comp ratio) we were approx +20bhp over them

but we had lairy cams, high comp, a map not done by Stevie Wonder, amd a few other bits and bobs

stock head is pretty good!

Just seams a awfull lot of cash for such a small gain

 

[kevin_172]

Well it's a brand new head and that's the work that's done to it so 15 bhp or there abouts?

 

[Fred@BTM]

that one off evil-bay for the turbo lump?

about 5bhp tbh, most of the extra IMO came from the high comp

 

[kevin_172]

Well my head is naffed anyways so any gain is good spoke to andy and sean and the guys at CTM do excelent work so we shall see! And yes it was off gay bay

15bhp, unfortunately i very much doubt it fella....

tbh if you head was gubbed and you got it done its cool, if your head was gubbed and you didnt do it you would kick yourself.

 

[kevin_172]

Well we shall see on the rollers

 

[Fred@BTM]

new cambelt, seals, gasket, headbolts, special tools, etc etc etc, alot of effort!

 

[kevin_172]

Well I ain't gone cheep on anything yet fred soooo we shall see! I would hope to break 230 on the car in the long run!
