Futral says the F13 makes power up to 6800 rpm, with dual valvesprings rated to .650 lift what would you set rev limiter/shift points at?

TIA

 

Look at they dyno from the tune if you really want to be exact about it, see exactly what it does in your car. Then go from there. Is this in an A4?

 

It won't be an issue w/ valve float. Its more of an issue with how high you're willing to spin your motor. I'd say for best track times shift around 67-6800. If you want to make the shortblock last a little longer shift at ~6600.

 

Yes this is an A4, this is a daily driver so Im looking for the best power/reliability compromise. So does 6600 shift, 6800 limiter sound good?

 

I shift a 6600 and have the limiter at 6800. Cam is on a 112+4 and peaked at 6300 on the dyno.
