i am very surprised they would differ so much no matter what's stuffed into our cars. with the engine offset to the right, that's already in our favor.

so what's the plan?

Looks good to me. Your LR is 130 # heavier than the LF. and your RR is 125# heavier than your RF. that will give you very equal cornering balance in both directions. The right side is light and so you may have a RF brake locking before the LF but all you can do now is try to move weight to the right front. This is the problem w/ a relatively light car that plops the driver barely in front of the LR wheel. You can crank a little ride height into the LR,assuming it's low, which will help the RF brake lockup by adding weight there. But you can't go too far w/ that or the cornering will be messed up.

Those are really good numbers Erik. I get a kick out of guys that tell me their cars weigh 2200 LBS and have never had the car on the scales. If they only knew what the car really weighed. Mine is within a few Lbs. of yours at 2745. I wish more would take weighting the car as seriously as it is. Off soapbox..........

I think my Engine and Tranny package is another 74 lbs when compared to your 302's....so not bad in my book...I have plenty of "umf" to push the extra "stuff" down the road anyway

your power to weight crushes mine. 2433/420=5.8 compared to 2689/575=4.7

your car must be ridiculously fast!

I just put a bigger turbo on an Lotus Elise and had it on the dyno today, 338 rwhp and 1940 lbs. 5.74 lbs per HP worth of pure fun!

Is that with you in it and fuel? If so that is impressive. I'm about the same as Erik's. Cheers.

That's without me in it. But it does have a lakewood heavy as crap bellhousing, a supercharger, two turbos, air to water intercooler, intercooler pump, intercooler heat exchanger and an iron block DOHC 4.6 motor. The extra weight is worth it everytime I open the hood for someone. It usually takes 15 seconds for them to see that it has turbos and a supercharger

A little different class but when I was running my DSR the car weighed about 850LBs with 3 gallons of fuel with 195 HP which is 4.35 LB/HP and would generate up to around 3500 LB of down force.

2270 lbs scaled (some fuel no driver) 425 bhp. (RW dynoed 360hp)

5.34 lbs / hp

I may not be up there with the Big Dogs but it is one Hot Hot Rod with excellent street manors on Goodyear Blue Streak tires.

Found an added benefit of corner weighing the car....as the tires are lighting up going through 50-60 mph and through 80 mph the car tracks VERY straight and no more tank slappers.....very cool! the car is A TON more sure footed to drive....what a blast!
