Some recent dyno graphs - ZR-1 Net Registry Forums

I dyno'ed the car this weekend on a SuperFlow dyno. Nothing changed since the last time, but I was interested to see it on the same dyno as I'd done other baselines.

Long story short, it peaked about 372hp. On the dynojet at Marc's it was 383hp.

Here's the gain from a ported top end and exhaust to adding headers and Marc tuned it:

The car always has some spark retard on the dyno because I don't get to WOT it on the way there much. If they did a few more pulls it probably would have gone away. That's what I see on the street/strip too, the first few have some KR, but it goes away. The gain at the peak was about 21hp.

Also we ran the car with the key off. Here's the full power vs normal power graph. The power peaks at about 225hp.
