adhawkins Posted May 28, 2006 Posted May 28, 2006 Thanks for correcting me. Should I have said 'rocker cover'? Nope, crossflow is a pushrod engine, the cam is contained within the block. Okey dokey, something else to add to my list of things to 'parrot' Andy Quote
cockerchumps Posted May 28, 2006 Author Posted May 28, 2006 The roller operator did just offer the results (129 fly - 84 wheels) as an estimation with no supporting evidence, but I am starting to doubt his expertise. I may remove the gearbox while I have the chance just for a look see. It be honest I don't know what to 'look see for' as far as bhp losses go but it may help me with my overall understanding. Quick question, is it a mammoth task to switch to a 5 sp box (type 9?) from my 4 sp bullet? Quote
Kevin Wood Posted May 28, 2006 Posted May 28, 2006 I wouldn't take much notice of the losses measured at a rolling road. They are far removed from what is happening in the real world when your wheels are in contact with the ground. You will have far more friction driving a couple of rollers than with a single point of contact on the road. Your gearbox and diff aren't cooled and would therefore overheat very badly if they were losing you any more than a couple of BHP. Kevin Quote
chazpowerslide Posted May 28, 2006 Posted May 28, 2006 The harder the car is strapped down on the rollers the higher the losses will be plus you hace two contact patches per tyre not one as you would on the road. Kevin is correct in saying not to take much notice of the rolling losses. Chaz. Quote
cockerchumps Posted May 31, 2006 Author Posted May 31, 2006 Thanks again. The cam is a KC234 G, I don't suppose anyone has the valve settings to hand? Kent's offices are obviously closed. If not I will have a look on their site. Regards Peter Quote
cockerchumps Posted May 31, 2006 Author Posted May 31, 2006 Kent's site gives VC's of, inlet 0.56mm and exhaust 0.61mm. Do these sound about right? Regards Peter Quote
cockerchumps Posted May 31, 2006 Author Posted May 31, 2006 That's (in old money) inlet 22 thou, exhaust 24 thou. That's practically standard ford cam clearences. Can someone confirm this as these clearences seem big to me. Regards Peter Quote
Martin Keene Posted June 1, 2006 Posted June 1, 2006 They seem quite big, allow me a minute to check and confirm. Quote
