i would guess 180psi+ on a healthy 1.0 (with stock 196deg duration cams)

How about a 1.0 with 1.3 cams?

How about a 1.0 with 1.3 cams?

probably 10 - 20 psi less, 222 duration on the 1.3 cams, inlet closes 42deg abdc (1/4 up the stroke) as opposed to 16deg abdc with the 1.0 cams

Ok, thanks, will check the compression on my 1.0 with 1.3 cams.

np, you might want to check the timings too, i had to advance my misses,s (1.3 cams in a 1.0) a fair bit

When i installed the 1.3 cams, i used all the stuff from 1.0, and the timing is the same as 1.0 i think. Wasnt suppose to be like this? My car runs perfectly...

i got this on mine today frank
test1 test 2
Cyl 1 185 173
Cyl2 125 160
Cyl3 169 170
Cyl4 170 173

160+ sounds pretty normal to me belly

i was just thinking with cyl 2 being lower than the other 3? or is that not a problem?
