What is your planned trap speed and shift RPM?

Click here for the calculators.

The gear stuff is at the bottom.

If you are using a slick factor in some growth on the top end. They may have a .5" higher average 28.5"

The other factor in converter efficiency you will have some slip as the converter is not a true 1 to 1 coupling. I would plan for at least 5% when selecting a gear ratio.

Are you factoring in the No2?

What speed are you planning on trapping at?

Autos do not always need the low gears like a stick car due to the torque multiplication.

4.30s at 2500 RPMs on a 28" tire will give you 48mph. On a 26" 44MPH.

Just something to consider for street duty.

On the bottle, you're gonna need in the range of a 4.11 on the very high side and a 3.73 on the low.
That's if the converter is set up for the bottle.

im figuring without the bottle for now want the car to run close to 11.50 for asfsc till next year then set it up for 10.00 class and would like to run for points at speedworld next year hey bill do you dyno tune with sct chip i have two cars that need tune with chip one is supercharged and other is N/A maybe give me two car discount LOL

Yeah........we can handle your needs for tuning with a chip. I'll give ya a HPS member discount and treat ya right.
I'll bet we can get your car to 11.50 pretty easy with 420 rwhp. Once you get the car ready for the track, all I charge for helping you dialing the car in at the track is pick me up, pay my entry and plenty of cold water and I'll work with you all night. That's what I do for PSR customers.
