Adj Cam Gear Adjustment, Need To Change Pfc?

[Bass Junky]

Hey ppls.

Well, you probably all know about my loss of power after fitting the Tomei Poncams.

Well, here's a question.

My exhaust cam is set at 2 degrees retarded and the tune was done like this.

If I set my exhaust cam back to 0 and reset the base timing, will this make a massive difference to my tune, and will I need to get it back up on the dyno and adjust?

I wouldn't think that I would need to, as I figure the airflow has more to do with it than 2 degrees of cam timing, but I've been wrong before.

All help appreciated.

Do you mean you've fitted tomei poncams? or cam gears? cos they are 2 different things! cam gears change the timing and the poncam cams are the actualy camshafts - I haven't heard many people losing power from fitting larger camshafts, but I have heard many people losing power on cam gears

I've fitted Tomei Poncams, and I also have an Adjustable HKS Exhaust Cam wheel.

We fiddled with the cam gear when tuning the cams, at 4 degreed retarded we made same power as 2 degrees retarded, and at 2 degrees advances we made 30rwkw less!

So we played around a bit, but ran out of time to set the exh cam gear to 0 degrees.

Hence, I would like to try this and see how we go, but I don't have a had controller or dyno at my disposaal.
