I run a toilet bowl,so changing air input I would have change to change complete tune up,no throttle stops are allowed in this class,car weighs about 2500# with me,taking off in high could be pricey after a while,have tried leaving easier and shifting early,can't seem to find a consistent combo,Iam considering buying another pumkin and starting with maybe a 4.56 ratio and working from there.Hey Lively if I was driving a ford I'd already be running a 5.90.

toms131,
A stop screw under the peddle (as Todd74 suggested) is not considered a throttle stop. We did this with Jimmy Smiths car (a member here on RJ) when he was running a stacks injection on Alcohol. The car would run .650's and he wanted to run the 7.00 class, so i'm sure it would work a toilet bowl, and it doesn't effect the 60' times that much.

Not knowing that taking off in high gear will hurt my trans for sure,but I did try it like 3 pass's in a row and noticed that trans temp seemed to get higher than normal every pass so I went back to low gear launches just to be safe.It may be o.k. for dragsters and cars lighter than mine,I just can't afford a trans and didn't want to risk it.

You leave in low gear and shift it within 600-800 rpm of the launch. You want the low gear launch so you still hit the tire to get out of the beam but you are shifting quick enough that you most likely won't get a full revolution out of the tire. When I do this with the dragster I can go from running 4.80 to 5.20-5.30. All out the car will mph 145-146 and shifting right away to high gear the car will run 141-142mph. I have done this 1/8 and 1/4 mile. No issues with heat and my converter is very loose.
If this is inconsistent for you, the launch rpm may need raised. Where do you normally launch and shift your car at? Is it a glide or 3 speed?
