Jessel valvetrain, not sure which lifters (I think they're .904's but don't quote me on that)

Spun it higher when we ran it out to about the 1000' ish

I really like doing them. Only limited by the amount of inputs to the ECU. I haven't done anything other than our BS3 logs yet. I want to do some with the Holley and Fueltech. Just haven't messed with it yet.. plus some people are very secretive on their data.

You get me the video, and the logger file and I'll gladly do it.

Create a list of the proprietary data that you're ok with having out there and I'll get going on it.

You guys coming to the shakedown? I can do it then, we'll be there.

You should have seen the grin on his face after that hit.

I told him it'd go .30's on a decent surface

That's getting it done with a DR and is this a Single 98mm Garrett? I'm assuming the stroke is short with larger bore, over 9k RPM is awesome! The overlay gives true demands of a fuel system! Great stuff !!

Fuel system is pretty simple, has a single Weldon Electric pump and regulator with a set of Moran 235's. Even at that power level they're only at 70% DC.
