Default new dyno #'s

We did a little tweaking on the car this Sat. trying to resolve a slight low RPM stumble. We got it a bit better and played with the WOT tune a touch while on the dyno.

results were pretty good IMO

457 rwhp
417 rwtq

A/F is 13.4 max and mainly 13.2 at the exhaust pipe, but my in car wideband shows 13.0-13.1 which is what I go by. We did put a touch of fuel in the car after this run to be safe.

I run mainly 93 octane in the car around town and 100-110 at the track, so we feel it should be good.

I hope to be at the track Sunday testing a little NA.

440/411

new intake
few miles
few tweaks

The car should really shine when I can afford to put a real top end on it.

Nice #s, Larry

So what exactly do you consider a "real topend" just out of curiousity?

Colin
thanks

top end wise...some day

some worked AFR or TFS heads & carb style intake

I think the car would make some really killer power with the above. This will be awhile since I want to work on some interior stuff and N20 setup.

I didn't notice this before, but I like the little 360s at the beginning of the graph.

The car did one back flip before it got down for a good run. I'm glad you like them.

I was looking forward to seeing the #'s on your new setup. I hope it comes together with no further issues for you.

Thanks Mike...I know I have said it before, but I'm more then happy with the car. The attention to the build worked even better then planned. We will get that Formy on the dyno again soon.
