First time dyno#'s - good or bad?

[cobra808]

Just dyno'd car for first time.

Mods:

Magnaflow catback
Densecharger
3.2 pulley

Cooled down for about 15 minutes; 87 degrees outside.

Pull #1 410rwhp/400rwtq
Pull #2 415rwhp/405rwtq

A/F was low 13's up to 3500rpm then down to low 12's high 11's

Slight dip at about 6000 rpm.

Opinions please?

I think the numbers are about right for 3.x pullied car with no chip/tune. You get the A/F dead nuts on, add some timing and you'll probably see the Hp and torque jump up 10-15hp/lbs.

Wally, Those numbers are right in line with the average. The heat here in Hawaii will play a small part on lowering them, but like was stated about, good amount more HP/TQ to be found with a tune. Congrats.....

Thanks Bo.

Looks like I got quite a ways to catch up with your numbers though. How's the KB coming along?

I have just about the same mods. See sig for dyno numbers. Weather was probably in the upper 70's and really dry.

Great numbers Wally, Congrats!!!
I went down to the shop to try to catch the dyno but I didn't see you.

Must have just missed you. Left around 11:30ish.

Did you dyno today?

Looks like my numbers when I had the 3.2" pulley. See my sig for mods (very similar) with the only extra mod I had was an x-pipe with cats. My two runs were 420.3rwhp/410.9rwtq and 424.0rwhp/407.3rwtq SAE. At low rpm, my air-fuel was 14.5:1 and slowly made its way down to 10.5:1 at 6500rpm. I ended up buying an Afterburner and ended up with a best run of 433.6/408.7 with a much safer (IMO) air-fuel, 12.5-11.0:1.
