Like the title says, can I get a definitive rev limit for this combo? I finally bought a tuner 'cause I'm changing out the gears. I tried using the search function but can't find a satisfactory answer. By the by, the car also has 115k miles on the clock, so I'm trying to be reasonable.

TIA,

David

Get it on the dyno and see where the power drops off. Shift it there. You can run it up to 6600 rpms if you wanted and would be just fine.

Comp cams told me the 918's were good to well up into the 7,000rpms. 7,700 was the number quoted to me (not sure I'd want to test that number ).
So like you said, use the dyno to pick the sweet spot.

Just like the two before stated, your horsepower will drop off before the valvetrain becomes an issue. I have a TR224 cam and 918s and set my limiter to 6800 but when I used to race I would set the shiftlight closer to 6400 so by the time the eye told the brain to shift, it would be right around 6600.

6500 if you want to be safe... shift at 63-64..

Want to be a tad more aggressive? 6600... with 6500 power shifts

My rev limiter is set at 7000 with my 918's. They seem to work fine at that level.

With an LS6 cam, I figure you'll probably want to shift at 6300-6400, so I'd set the limiter for 6600. The Comp 918s will be more than enough to handle that for a good long time...

thanks for the responses. I think I'll stick with the conservatives on this one.

On mine, my limiter is at 6600 and my shift light comes on at 6200.. works great for me.

For an A4 the best way to set the shift points is trail and error while live data logging.
Basicaly you will set your shifts to keep the highest amount of max hp powerband between shifts.

Stock lifters with 115K on them?

with that kind of mileage id upgrade my whole valvetrain and get an upgraded timing chain and oil pump.



i have my car set at 6600 but i have ls6 springs and an auto.
