As some of you know I am turbo charging a C20XE engine and people have said that there is not much valve overlap.
Can some one explain why this is bad and what will happen as a result.
Also I am thinking of getting adjustable cernier pulleys to try and help it out but which way do I adjust them. Do you have to adjust both inlet and exhaust cam or is it just one or the other.
Probably one for John A to answer as technical content welcome.
