Just ran my TA for the first time with mods in sig plus LTs, 3600 stall, 3.73s and Nittos. I was extremely happy with my 60' and 1/8 mile times but I feel like Im lagging in the 1/4. The outside temps on my slips were betwwen 88 - 94 and the DA was around 3400.
Should I have a better 1/4 mile with my mods or is this about right taking temps into consideration. My previous best listed in my sig was run on an october day around 70*. So I was thinking I should try and get times on a day comparable to that, but the problem is I probably wont see those temps for another month or so.
Any comments appreciated.

Sounds like the conditions fought you off. Wait for better weather.


Awsome 60's!!!

That is what I thought. I feel like there should be more top end. I remember reading people with high stall convertors running better times but their MPH was slower than before TC. Why does this happen with stalled cars?

COMNBYU

A lot of times when traction increases you loose a little MPH.

Other times, you might have MPH to run a certain ET, but not the 60. So when you finally get that traction you don't really see any improvement in MPH.

That's why you'll hear a lot of people say that MPH is a good indicator of HP.

For EX- your LS1 makes 400rwhp with bolt-on's, a cam, and tune. You run it at the track with a stock A4 (no conv.) and street tires. You run a 12.8 @ 115 with a 2.1 60ft. You then add a 4k stall convertor and ET Streets and go back to the track. You run a 11.8 @ 115 with a 1.6 60ft. You didn't gain any MPH, but lost 1 whole second on your ET. That's because you had the power to run faster the first time you were at the track, just not the traction. Once you got the traction you ran a sensible ET, BUT the power is the same as it was the first time at the track. You didn't add anything that gave you more power, just more traction.


Obviously that's just a hypothetical EX. Get it??


Hope that helps

Looks good to me for summer air!

Unless the track is another 1000 ft above sea level, I'd say 12.20's or 12.teens in good air.

Nice job!

Pretty consistent times too. Get that r/t down a little better and you'd be pretty good @ bracket racing.

Those times look fair for the summer heat which stall do you have and what does your car weight....
