heh, here i am!
yep, 4 shafts, inlet x 2 and exhaust x 2. 6 lobes on each.
Theres 4 valves per cylinder (hense the 24 valves, 2 inlet, 2 exhaust on each).
Funnily enough im looking into these at the moment as FI just seems out my reach for the foreseeable time being.
The lift is indeed the height the valve is pushed open, and duration the length (or degrees) the valve is kept open.
If youre going for cams, personally...... dont go with it unless its proven.
Reasoning being, if you get lift/duration thats too high, you'll ahve a power curve that doesnt kick in till much later, and by then you'll need a higher rev limit - which means standalone ecu or begging me for the smt secret wiring diagram to extend the rev limit
To be DEADLY honest... theres no point at all disabling the vvt, you wont be able to without megga cash anyhow and it wont do alot.
Cost - you'll be looking at around £200 for regrinds, £450 for the proper billit custom made ones from catcams
ecu £300, fitting £150, tunign £300 (approximate figures)
with that cost in mind, only use ones where you can see a before and after - otherwise you'll be bitterly dissapointed
Also, whilst im on teh topic of Catcams – give Matt a call @ QEP in Hassocks 01444 243720 as im sure they can also do regrinds.
I have heard some bad press about piper in the past, and using matt before, id 100% recommend him again.
Some people talk the talk because they know jack-all. Whereas others, like Matt can talk for hours about cams because he geniunly has a passion for the things.
Bearing in mind, this is the guy that after James Green completely ruined Aarons car – one call to Matt and he knew what it was just by verbal description on the phone – something james couldn’t figure out for 2 months.
