The 78 is great for the street, spools very quick. Motor is stock other than pushrods/springs/cam.

Your rx7 is awesome. I'm hoping my 240z does as well. It should be running later this week hopefully.

What kind of exhaust are you running on it? I loved the second video by the way.

80's, idle is fine with e85, duty cycle I believe was around the high 80's, would have to go back and look at the logs

We tried no intercooler, and saw IATs shoot above 180*f in a matter of 4-5 sec on just 8lbs. It was a bit higher then what we felt comfortable, so we shoe horned a 31x12x4 intercooler I had laying around into the front end. IATs never rose much over 25* during a pass after that with very little air flow to the intercooler.

E85 on a blow through set up, Im sure no intercooler would work fine, for an EFI car, I would lean to some kind of intercooler.
