Wouldn\'t depend on porting of the engine too ? Mine on stock ports runs out of power at about 6500 so doesn\'t need to rev past 7k. Streetport and Bridge are higher but by how much ?

peak power on stock ports is around 6500 but the power does not suddenly drop of after that, but Shaun if you are changing up at around 6.5K then no wonder your quarter mile times are not as good as they should be, I would be changing about at around 7.5K as then your revs drops should drop right into the power zone.
My peak power on my half bridge is around 8100-8200, I will be a raising my rev limit to 8400 so I can change up at around at around 8200, as I hit the limiter on the strip a few times at RS

No I was shifting about 7k to 7.5k on the strip. I think the wind didn\'t do me any favours and my air temps where terrible too !

I just wanted to point out that there was no point in setting it at 8400 if the engine is a stock port even with a huge turbo !
