rev limiter question My comp cam will be installed next week and I dont have anyway to move the rev limiter up a bit. My question is do you think I would be losing much power by using the stock rev limiter? the specs are
218/218 .563 114 XE grind. TIA

Re: rev limiter question definately lose time at the track. you might not lose dyno hp since those are realitively low duration so your hp peak should be around 6000 rpms verses 5500 stock. you would want to shift around 6400 rpms to get the most out of it in race situations. but if you are not interested in that, dont worry about it

Re: rev limiter question actually the peak horsepower in my car is exactly at 6k right now. Its weird, I will try to scan the dynograph if I can. So you think I will lose that much time at the track?

You want to shift a bit past your peak HP point so that you enter the new gear well into the range where your motor makes power. If you shift at or just under 6K (don't remember exactly where the stock rev limiter is...) you will be coming in far enough under the RPM range where your engine makes power that you will spend more time getting the engine up to speed than you would have spent winding it past it's peak HP.
At least... that's the way I understand it.
