Hello everyone,
I need your experience about the clearance of the valve guide to valve.
Now i change the old ones into new BC Racing and set the correct high as well.
The factory tolerance for intake side is 0,02-0,053mm and exhaust side 0,04-0,073mm
Now i set 0,03mm for intake and 0,04mm for exhaust side.
But at the moment iam not shure if the clearance ist right for racetrack application and around 450hp.
By the way, i build a complete new engine for racetrack use.
Can you help me with good experiance from your build,please.
thx a lot Dominik
