2010 SS L99 Performance

I have headers, CAI, exhaust, cat deletes, jennetty tune. My best time tonight was a 8.55 with a 2.05 60ft 85.2 mph. I feel as if this isnt that fast compared to the fast list. what do yall think?

Your 60ft time isn't so hot and can net you a big gain with practice. What are your RT's? Been playing with the air pressures like I suggested in your other thread? DA has a lot to do with ET's as well... Are you running in Sport Mode? It gives the most consistent shifting and will yield the best times....

Multiply your time by 1.6 to get NHRA full 1/4 mile times if interested....

13.6 1/4 sucks after all the money I have in it with these mods. Alot of stock cars are running faster than that

I think you calculated your times incorrectly. I had a 2.190 60' along with an 8.55 1/8th at 87.62 mph and still ran a 12.95 @ 112.27. And that night I ran a 12.9 twice and a 12.8 once. And that was on a 80 - 90 degree evening with a bad DA. My SS has every bolt-on available. So I'm not sure where you got 13.4 from but I'd say your 1/4 mile would have been more like a 12.9 to 12.8, maybe even better. Only way to really know is to actually run a 1/4.

As far as the fast list, you can't really compare what your car does on one night at one track in one state to what another car does on a different night at a different track in a different state. There are many variable to consider that may affect times. DA plays a huge factor. You can probably lose up to a second depending on where you are in the country. For example, my 12.8 corrected to a 12.1 if I had a perfect DA. And second, I don't know how much of those fast lists and 1/4 mile times from magazines I believe. I think the mags are somewhat accurate in telling you which cars are faster than others stock to stock. But I that's about it. And these fast lists, I say let these people run side by side with you and then see if they're really running these times. Maybe they are with a really good launch on a perfect day with a good tail wind. But outside of that, nope.

If you aren't spinning the tires thru 60ft and have a 60ft time like that, there is something wrong for sure. Make sure you have the TC off, it will kill the party big time... You may need to lower the tires pressures even further if you still have wheelspin.

The 1.6 factor I gave him is what NHRA uses for conversion from 1/8th - 1/4mile... You may have used the 1.55 or 1.56 conversion factor that a lot of people use, Why, I don't know, but it is listed out there a lot...

I didn't use a conversion factor. I just compared my times and my MPH to his. He had the same 1/8th time as I did. Yet my 8.55 took me to a 12.9. And I had a few slower 1/8 mile times that same night. Yet I ran faster than all the conversion factors said I should have run. Some of my 1/8th mph were slower than OPs. Example:

I had an 8th of 8.71 but a quarter of 13.12
I had an 8th of 8.60 but a quarter of 13.02
I had an 8th of 8.86 but a quarter of 13.30
And on a different night I had two 8.6s that both turned into a 13.0
And there were 3 other cars. 2 ran an 8.99 in the 8th with a 13.8 quarter, the other one had a 9.01 in the 8th but ran a 13.5 quarter.

By all the factors, I should have ran slower times than I did. The conversion factors are ok IMO, but I still say you have to actually run the full 1/4 and see what that times comes out to. I think OP would have ran more like a 13 flat or 12.9.

I hold the tc button for about 10 seconds until both lights come on. I do a burn out with it in M1. I have tried just scuffing the tires to holding it until they boil smoke. pull up to the line i shift it to neutral and back to Sport mode. I have tried from a dead stop up to about 1600 rpms. It doesnt spin at all on take off. it spins when it shifts to 2nd nomatter if i have 22psi or 34psi. i ran about 15 times last night. and varied the tires pressures. my best time came at 30psi i ran a 8.48. i was on my brakes trough the trap. so possible low 8.40 run. i paddle shifted that time also and shifted on rev limiter. i think my best 60ft was 2.01, ill verify when i get home. will the 330ft time help yall? how do yall recommend taking off? i also took Ted Jennetty's tune out and put in Superchips tune. My best time on his tune was 8.55 i believe.
