Exhaust Cam Rb20

[dangaz]

Hi all.

I'm putting an adjustable cam gear (exhaust) on the car this weekend.

A few questions.

Apart from the tips in previous threads, how will I know what the ideal settings on my engine will be without using a dyno???? sounds, idle, response etc

What are the worse case scenarios if I balls it up????

How much more rwkw should I expect???

Rb20, 25 turb, FMIC, Filter, Turb back exh, bosch 040, Dr drift ecu, 12psi 173rwkw.

Any answers or suggestions will be appreciated. cheers Dan

Why dont you want to use a dyno?

If its a funds issue install the gear and leave it set at zero till you can get on one. Should only be ~$120.

I wanted to put a few more things on the car before I get the ECU remapped again, just to save going back and forth, is a dyno necessary?? could I listen out for big bad sounds? would you know of the worst scenario?

Worst case bent valves. You are not going too be able to tell which way does what on the road you really need a dyno you could probably just set it to a position that other people have found to be good with rb20's.

bent valves bad, straight valves good.
