Bargain, very tempting but ive not finished this one yet!

Did the cam timing today, thanks again Jason, it turns out i had far to much advance on it, the first set of measurements found 3.35mm (132 thou) inlet lift at tdc. I have adjusted it and now repeatedly getting 103 thou inlet and 95 thou exhaust, as near as recommended, i will get it back together later on in the week and see how she runs

Jason, sorry to bother you again, just to clarify am I dropping the dti onto the bucket edge or on top of the shim as i did it to the bucket edge and this could be why it was so far out  :-\

You should see a pretty noticeably difference now you've corrected the cam timing Mark  ;D

Ideally you should do it on the shim in as near to vertical position as possible, so as to get accurate reading, but at the end of the day they both move together so shouldn't in theory make that much difference!

What he said!  ::)....lol!  ;D

That was certainly a bit too advanced Tim!...not a bad guess on the cam timing eh...hethum!...lol

So you have around 8 thou more inlet lift which is a start. When time permits, it maybe worth marking the pulley at that point, then advancing a touch more to say 12 thou advanced, and 15-16 advanced, and mark each step on the pulley...you then have 3 setting points to test on the rolling road the next time and see which gives the best overall spread.

Tim (Moll) found more advance than the norm works better on his set up, but his cam is a lot wilder. I can also confirm the red MK1 drives superb...a really good first step track car...user friendly...whoever snaps it up wont be dissapointed... ;)

Not a bad guess at all :)

As recommended had another play, its such a small adjustment, i started off a bit gun ho, but have got 3 decent positions, that all fall within one increment line on the cam, about 10, 15 and 20 thou advance give or take, smaller increments proved pretty difficult with my sausage hands.

I had previously fitted the metering head from the cabby to tim on it really seem to smooth out my spluttery bottom end, just needs setting up pressure wise i was toying with getting an innovate wide band meter, but might just save my money and put towards another rolling road sess

Thank you for your help boys, looking forward to putting her back togther over the weekend and having a blast :)
