Bro, my motor is done CDB 2.1 built stroke cams etc etc. Im picking up motor this weekend and hopefully have it dropped in by next week. I'll let you know how it goes.
I paid around $250 for my road tune by papu a few years back and I was very satisfied with the results, I also had my car tuned my Garry Capper and did not notice much of a gain this was on the same setup.
Yup, even if there was a lot of cam timing or avcs advance added on the intake side, wouldn't all the intake valves kiss? The exhaust is not controlled by avcs just a cam gear, but doesn't explain why the other cylinders don't have valves marks on the piston.
Do you know whats the maximum decking limit for the block and max machining for the head is ??
Cam Lift:
Intake:
11.50mm
Exhaust:
10.75mm
Intake duration 272 and Exhaust 268. The adjustable cam gears was 5 and 7 degrees. I was told there was 4.5mm PTV clearance.
CP piston off NZ Performance, it was early square dish type. The thing with my motor some of the intake valves have touched but not all, on the other hand I don't have avcs on the exhaust side but 2 exhaust valves have kissed cylinder 4 piston and the others have nothing at all.
I'm after some of your guy's opinion, have you ever had valves kiss the piston because of a tune i know this may be a stupid question but im only after your insights. I know if you run a lot of advance on avcs there is a chance that your valves would kiss the piston, this is mostly on aftermarket cams, but an engine builder would usually check this and tell you how much you can run before the valves kiss.
