Default Dyno Time!

I finally had time to get the car on the Dyno.

I took it to Under Pressure Performance, here in Colorado Springs. They specialize in custom turbo installations, but can tune almost anything



My goal was NOT maximum power. I didn't give them a power goal - the parts are going to make what the parts are going to make. I wanted good power, with a flat torque curve, and conservative enough to last just about forever. They did a pretty good job; 418hp, 405 ft/lbs.



More details can be found here: Engine Basics and Selection ? Racing the Exocet

.boB those are really good numbers. Looking at the graph it should be a really smooth engine.

That should get it around the track and most things ON the track as well!

Congrats!

I haven't had it on the scale yet (soon). But I expect to be around 1700 pounds or so. It won't be the fastest car on the track - it would need a better driver for that. But it should be a real hoot to drive.

Thanx, all. I can't wait to get it out on the track in a few weeks.
