MSD rev limit tech question., Bill Pickering? Options

[Trekkor]

Got the odd increment pack.
The mechanical rev limiting rotor was a 7300 unit.
I replaced it with a standard Bosch rotor.
I've been running on the provided 7k MSD pill.

I guess my question is, how high can I safely rev my SIX at the a/x for short blasts?

Thanks Brant!

I appreciate the encouragement. Actually, it will get easier this summer to deal with once the car starts being re-assmembled....at least it won't look like a carcass... (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

Trekkor,

I agree with Brant, the motor life is all about the redline. Jerry Woods and I settled on the stock redline for my 3.6 that they are working on. The motor itself has been warmed over and there is more room to push the limits, but when we talked about what I wanted (reliable power) he said the quickest path to death is revving it's little neck. So we stayed conservative.

As I mentioned in my previous post, we have reworked our WEVO 915 to have a close ration box, with a much taller first gear. Basically we matched the gearing to the Torque range of the motor from it's dyno runs. We have 75 MPH available in the first 2 gears. Auto-x in first and second, use all gears on the track....

Re-gearing if you can do it helps keep the motor in the sweet spot. It allows you to make the most of the available power without stressing the motor to all heck...
