weight.....help

wagonboy · 01-15-2010, 12:47 PM

I have a 1980 malibu wagon. classification with a 305 makes it a natural M car. (14.33)- it has been run as a "N" car. The nhra tech sticker on the car says wt 3405 cid 305 hp 180/230. I have tried to figure that weight - is that accurate ?

N - 14.50 to 14.99

14.50 * 230 + 170 = 3505 lbs.

Looks like a mistake on the sticker, it's 100 lbs light.

thats what I thought. I like the mistake number better!! I knew I could do math ! With the new rules, can a natural M car weight down to O ?

You can run 1 class up or 1 class down from it's natural class (M).
L- 3275 lbs
M- 3390 lbs
N- 3505 lbs

Jeremy K . Is exactly right, up or down one class from natural class only !!
Good luck with your project...............

wagonboy, you can change the header panel to make your wagon a1983, then you can run M, N, O. Tom

ok, bear with me here. If my car fell into N naturally - would the recipe for weight be 14.50 x (hp) 230 = # plus driver weight OR would it be where the car falls 14.66 x (hp) 230 + # plus driver weight. I understand if I move to O- I would multiply by 15.00- the lowest number. Question is for my natural class would I use the 14.66 or 14.50 (min) ?

Thanks

Ryan

You can use the top of each class' weight break to figure class minimum weight. 14.00 (M/SA), 14.50 (N) and 15.00 (O) x NHRA rated HP + 170 = minimum weight for each class.
