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.

What was it putting down before?

LS1 SPEED

iTrader: (22)

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?

Larry, If you dont mind me askin, what setup are you running, head/cam wise? Are you Solid Roller? Im probably going to be doing a 383 and would like to see similar numbers....

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.

Thats pretty sick, that car is making reall good power seeing that it's going through a stalled auto and S60.

Thanks for the link. After lookin at the pics of your car, it really makes me miss my mystic Z. Im guessing the 10.89 was on motor?

S60
CM driveshaft
28" radial tire

Thats great. 1 more question and im done. Who did your head work? If its LE or Ai, what "stage" head is it.

LS1 SPEED

iTrader: (22)

I had our machine shop do the heads.

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

In good air thats cars going to run it's *** off, should be cool to see some low 10s out of it.

thanks man

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

Thanks Adam

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.


oh yeh!
I think the car will really fly when out good air comes in a few months.
