Finally put my car on a dyno last night

[SuperSonic05]

I went to speed inc last night with grabber. I was a little disappointed with the number I got, but dyno numbers don’t matter only ¼ mile times. Hoped I will see a good increase from what I have planed for the some.

Yea 1/4 mile is where its at, dyno is just a number. Heck I think I dyno'd at 268hp and my best 1/4 mile is 13.3 so I just ignore my dyno numbers.

Is it possible you need to add more fuel in the tune? It looks like you are around 14.0 A/F. I had a 07GT/CS that put down 300HP without headers, charge motion plates, or aftermarket cats. I know dynos are different like cars. But I would recommend a custom tune if you can find a good tuner. The 4.10 gear probably doesnt help the numbers either. Comments?

You need a tune that A/F is dangerously high or speed Inc's WB is off

Send that to your tuner see what they say

Ryan those numbers are not that bad. Look at your TQ. However I would say your HP could be a tad higher. But with the mods you have, I would be happy. When I had Exhaust and cai only I did 285hp and 298 tq with a kurgan tune. The fact that you are at 322 TQ is about right for your car. Dont forget these cars dyno at 260 stock if they are lucky. I would say good deal and at least you know you can get a little more out of the car.

Yea I know that if you have bamachips or other mailorder, I'm sure if you sent them your dyno sheet they can adjust fuel a little to get it better, or you could just add more fuel with the tuner itself, but without another dyno you won't know exactly where it puts you.

Why not get a wide band their cheep now. You can hook it up to some hand programers and data log.

I second the need to tune for more fuel. ShowCarDetail and I had similar mods when he got over 300 and my dyno results were about the same as his, again, without CMDPs and stock axle forward exhaust.

Anyway, your 1/4 time already says your putting down better power than that dyno graph indicates. Try the Great Lakes Dragaway website for a calculator estimation of your HP based on 1/4 mile ET, MPH and the weight of your car. You'll be surprised. Again, even that calculator is only an estimation.
