Yes I'm local to these guys. I have fbo cj and long with e85. Shelby mani car will be dynoying his car again this Tuesday with new 8k redline. We both will have a big day

Yes he is. Should be a better comparison since he has 3.73 gears and same longtubes as gt350 manifold

What were the results with the GT350 mani?

This is confusing and there's no way the TQ is higher than HP.

I'm glad I went to the dyno, my car seems be reading false knock somewhere and is dipping at 7300 RPMs. Will send logs to Ken tonight! But fixing that dip not sure that's the 20whp I'm missing

Cobra Jet graph is green and shelby mani car is red

There's obviously something going on with the CJ car. Nice to see that the rest of the pull the intakes are almost identical.

What TB is each car running? Who's tuning? Is the CJ manifold ported?

Oh yea, definitely something going on in the tune on the CJ car for sure. I'd be interested to see what MAF lb/min are reading where the power dips, as well as ignition advance. There isn't going to be actual knock on e85, so something is up.
