Sorry, I thought that da was decentish. Last time I got it on a Dyno was a over a year ago at brenspeed, where I got the 451hp, and 396 torq, that was also after cooling down a lot, and I believe the temps were not bad like in the 70s.

Actually not on the same day. the glory part was race fuel, +2* timing, skinnies and no passenger seat. The DA was good, I even have the slower corrected time in the sig, I don't recall what it was.

Thats crap air... I don't excited until sub 500... though anything to up to 1000 isn't going to cost you a lot. I'm with Stkjock... good air has a negative sign on it.

mattstang2007

Yeah, either way, da corrected I still only got a 12.9...lol

Oh I'm not saying something isn't right here... Do you have a data logger?

mattstang2007

No, I have never data logged. Is there a way to do it with just a sct2?

Stkjock

yes, a few parameters, however, best to use the SCT2 and a laptop.

I'd kill for 2,000 DA I'm lucky to get 4,000, but that is mostly because the track sits at 3300' and they only run during the hottest months, although new owners seem to be keeping it open longer.

I think if you can find a cheap dyno to test your hp again might be a good idea.. Every summer there are a couple of dyno days and during car shows for like $50 get 3 pulls or something like that..

If your power is good then.. traction control was off right? or its one of the other things people suggested.. the only other thing would be not driving correctly..

If you do the data logging approach you can ask brenspeed what parameters they would look at and send them the results to look it over for you. When I data logged my car one time it didn't make much sense to me what I was looking at. I could see where I gave it gas and let off but the numbers didn't mean much to me.

Other then the bad launches, I thought my shifting was pretty good. Getting another Dyno is a good idea. I just changed the fuel filter after 42,000 miles, gas was dark brown, I am sure that didn't help. Considering I would have had a 12.9 da corrected and doing that whole 2 tenths off the top end per tenth off the 60, I would be sitting at an 11.5ish assuming I got a 1.5 or so 60(wishing I know) right about what it should be, so it looks like I just need tires to drop that darn 60 down. That rule still applies right, the 2 tenths off per tenth of your 60? If it is, do the number seem about right to you guys?

Stkjock

It's not .1=.2 on the big end. Usually a bit less.

However your trap speed seems lower then what your dyno numbers suggest it should be.
