Cooter,

Smart move to stay in J & I with a 350 / 268 combo ... Yes, G & H are very Fast classes, which means more bucks !!! Cooter, have you had the car out testing yet ??? Good Luck , see you @ VMP in March .....( CCRA )

Dave, I actually was able to make Darlington race at the end of last year and CCRA race at Dinwiddie, and Steven Rowe drove it at Reynolds lodrs race last year. Got some good data to go off and it's promising but needs a little work. I was looking forward to the division 2 races until I saw the schedule, it's likely that I only go to Dinwiddie and Rockingham for the start of the season.

x2 Gary !

The "ET - MPH - HP Calculators" in the first column. And the 'Gears - Tire - RPM Calculators' at the top of the second column are my favorites.
Hope this helps.

keep in mind that most of the online calcs use factors for a standard geared vehicle.
case in point : check the MPH vs ET on a typical street combo , say for instance 13..XX ET at 105 MPH.. now look at the ET vs MPH in a science car.. very similar MPh but a way lower ET.perhaps a .6 0r .7 lower ET.
To best work the numbers within a small window, just pick up a 10 buck calc that does CUBE root..
Now try the mph X 426.. now take the result and multiply it times itself two times i.e. 426x 125mph = 532 ..so .532x.532x.532= car weight as raced, say 3310 pounds...= 499.78 HP,. so plug that number(500HP) in the Wallace ... . all still following? that is common hot rod math.. now the calcs are set up with a factor for ET of around 5.8 ( usually 5.825) but a well setup drag car is closer to a 5.6 factor...So what you see are numbers maybe like an ET of 10.9X at about 124 mph... so instead of using 5.8ish use 5.6 like: 3310/ 500 = 6.62 Lbs /HP..now find the cube root.. 6.62 cubed = 1.877670269 x a factor of 5.825= 10.93 ET so try a factor of 5.6 for a well scienced car and you get 10.51. That should be about the ideal ET. case in point a previous record GSA car ran 125 at 10.58 .. pretty close for a 9.99 (plus tax where applicable) calc.. So you can back track and if you know the MPH and weight you can see who is making HP, got car hooking and who is full of./..A 3500 pound Nova that the owner says makes 600 hp and runs 118 mph is NOT making 600 hp.. closer to 450.. Yeah, you can run a 11.40 @ 125.. or a 10.50 .. MPH takes HP.. ET takes a complete package... Hope that helps and I was not too obtuse..
