How do I know if my 60' times are correct for my Car

How do I know if my 60' times are correct for my Car - 05/21/09 05:38 PM

Is there a comparable chart that will show where you should be at based on 60' time, and/or ET and or MPH.

My car is going 1.75 60' 12.2-4 at 107-109mph

I am trying to figure where I should work to get the car to a lower ET.

Thanks.

it's way off, you should be in the 1.56- 1.65 range imo.

Meaning a 12.2 ET should yield a 1.56-1.65 60' time?

meaning you're leaving et on the table in your 60'.. I was going 11.70s at 113-114 with a 1.61 60'.

What is the car and the combo ?? The weight , gear , cam , heads and so on have alot to do with your 60. Ron

That calculator is great, tells me my 2.0 60's are terrible to go with my 12.77. I should be 1.77 or so, guess there is more there.

I could be wrong but the too big 60 foot killers are 1 tire spin and 2 driving through the converter.
This means the converter is a little tight for the cam and where it is degreed and the car goes aways before it hits it's power band will act like a sudden increase in power like you just gave it more throttle.

And add that some vacuum actuated 4 barrels come on what to late with improper spring tuning and sometimes diaphram leaks and other problems.

My car runs 12.50's typically and 60's between 1.67 and 1.70.

Best ET was 12.37@106 with a 1.67 60 foot, so yes, you are leaving some ET on the table with what you have now, but you aren't terribly far off.

And according to the Wallace Calculator, my car 60's too fast for the ET it runs. I guess I'm an over achiever.

That's a step in the right direction, but you're probably not going to drop a tenth in the 60 just by swapping t-bars. Better plan to spend some time at the track tuning the whole chassis w/ that new combination.

well i knew it was off, but not this far off, 11.23 with a 1.67 60', says it should be 1.53, and its not too consistant either, any ideas,i have another converter to replace the coan in there now.

I have seen a sixty foot change from 1:43 to 1:52 from a low(180 ft above sea level) altitude track to a higher altitude(2500 FT ASL) with no changes to the car Traction ,parts, HP and torque help determine the sixty foot times

But Cab, the ET changed as well, right? The calculator determines the 60' based on the ET, so altitude wouldn't be part of that equation. It already affected the ET, so the slower 60' would follow.

The ET does change as well, your right. I don't use calculators to determine my results, just the time slips LOL, test, test and test some more to get results, good or bad

The calculator says I should have a 1.79 sixty foot, it goes 1.81 so it's pretty close. With worn out drag radials, SS springs, and truck shocks, I guess that's not too bad. My best ET is 12.91.

In other words your leaving before the converter flashes?
