SO I went to the track for the first time ever today I didnt do to great i ran a 17.58 booooo! I still had my 20s on so could that made a difference? what are your quarter times?

 

Yes a taller tire will slow your times down because effectively what you're doing is changing the gear ratio (which directly affects acceleration) a taller tire is just like putting in a numerically smaller gear set although it isn't going to affect it very much. This is all assuming that your 20" tires are taller than the stock tire/wheel combo.

 

I ran a 16 something with mine last time I took it to race. As long as your tires are the same size as they were with the 15's than it wont change anything. But if they are bigger/smaller it will make a dif.

 

That and the fact that those 20's probably weight a TON. Put the stock wheels on there next time you go you'll probably shave almost half a second off that time.

 

Mine will never SEE a quarter mile track or any other track for that matter. It wasnt meant for racing and definitely wasn't set up for it. I have a basic baseline model... so I know better. At least I can make her LOOK real good by the time I'm done!!

 

LOL nice noel!

 

how did you launch it? Throttle stab? RPM's up? It makes a difference how you launch 'er.

 

my reaction time was a 2.45 I dont know if thats good but it was my first time. its an auto so i just stompped it

 

AHAHAHAHAHA!!!! dude what the hell lol. but u gotta get that R/T down to about 1.9 - 1.8 lol. but if u put back on ur stock wheels ur times will get better.

 

You should be able to get better than that. You go when the last amber light turns off, not when the green lights up.

Now another thing to launch an auto is to load up the torque converter. Left foot on the brake, right foot on the gas up to around 1500rpm. You don't want to do this while you are waiting for the other guy to stage. Only once the other guy has staged. You'll put a lot of heat into your transmission by doing this which is why I wouldn't suggest it unless you are really into racing. And I definitely wouldn't do it without an external transmission oil cooler.
