i spec and build my engines for my intended use , and an engine with a low compression ratio does not perform in the point and squirt from very low engine revs/ vehicle speed in my game , hence the high c.r (thats high- not very high) i do know of people using alot higher than me ,

a little example for ya -

any of you seen the vw/audi/skoda/seat 1800 20valve turbo engine ??
well in the seat cupra R , it puts out 225 brake with a c.r of 9.5 :1 , now go and ask the tuners what sort of power they can achieve for not a lot of money at that c.r - its in the region of 300+ !!


so i have to say - i really agree with simons statements all the way,

as for the proof of performance , ive not done anything timed for a long time - about 3-4 years ago my car did 0-60's in 3.9 secs on an older spec of high comp engine

if my gearbox can be salvaged (come on bernie - dont let me down - please !! work them miracles), and i can be arsed changing my diff ratio , then i may have another go !! - btw it is 2wd !!
