they give small gains, it makes the valves open for slightly longer.
But ABF cams are pushing valves 1,2mm deeper than KR cams (ABF 10.8mm ; KR 9.6mm)
for example:
KR inlet cam
valve open at -3°
valve close at 35°
so 180°-3°+35°= 212° and cam pushing valve 9,6mm deep
ABF inlet cam
valve open at 1°
valve close 39°
so 180°+1°+39°= 220° and cam pushing valve 10,8mm deep
Schrick 268 inlet cam
valve open at 22°
valve close at 66°
so 180°+22°+66°= 268° an cam push valve 11,5mm deep
Mark, i hope you understand and know what will you get if KR cam open but also close valve earlier than ABF cam![]()
I would never change ABF cams for KR one. For those who want power earlier i recommend: sell the valver and buy turbo or tdi![]()

They where standred kr cams yes.
so dont do it ?
only reason i ask, is i no few people with golfs ect, and they all said i will get slight gains?
and my mates got an abf lump, which he is goin to put in a carado with kr cams and charge it.
i would go de-cat, but the police are funny around here, and now getting new toys (sound testing equipment)..
my exhaust is already too loud, £30 fine, but i want standered back box so its hidden

But unless you can get mots i wudnt bother
