only you would notice that ED i had some very sticky race tyres on,the hotter they got the more drag i got,ie wheel spin ,loss power.if you look at the graph around 6000 rpm the tyres lost traction thats with a ratchet strap over the wings.Ed said:Bob is that 30bhp Transmission losses???
pietro said:Bob would I get extra power with a 1.2 head or is the 1.0 head about the same? Also how hard is it to change the head (time, tools etc)
Thanks
Ed said:Without question bob that is an improvment. But im surprised at the wheel spin. I didnt get any on the ST with my last run at 183bhp, but I surpose it does depend on rollers.
