Fat arse stock car drivers

Using my 2009 DragPack Challenger example from earlier. 3,100 pound shipping weight, divided by NHRA rating of 390 = 7.95. Making it a natural AA/S car (AA = cars with weight/HP of 7.50-7.99). You can adjust weight to a car to 1) move to the top of it's natural class 2) add weight to drop one class from it's natural class 3) remove weight to move up one class from the natural class. To get to the top of AA/SA with a Challenger, 7.5 x 390 + 170 (driver weight) = 3,095 minimum weight, with driver, across the scales as a AA/SA.

Forgetting about the weight of ANY driver,could you even get a DP Challenger down to 3095?

Ill let you know in about 2 weeks....

I just lost another 20lbs today on the car, that in addition to over 50 in other places Ive lost.....I could another 10 but I am not going to do it now, it was a 2 day event in itself, worth it, but right now I know I can loose 10 more, I just dont want to spend the time to do it at this moment, I can do it in the pits at Pomona if I care to....

We are going very very trim with our car, everything hits the scales.....and I mean everything, if a lighter piece is an option it gets made and gets it, if it dosent need it "by the rules" in the junk pile it goes. We went light on everything, at the potential sacrifice of reliability, its all relative anyway....Id rather have weight off....cheapest HP I can buy....

I spent the better part of 3 days with a heat gun and wood chilsel extraciting all the urethane body sealer and sound deadener, it getting a "wrap" because its lighter than repaint by some 20 lbs, weve got supposedly the lightest wheels on the market (and that even from some of their competitors) By god I have no idea where were at but were as light as we can be....

Well see when it hits the scales after its all back together, Ive been told by all the other DP owners/builders noone has made minimum weight.....I dont know that we will either, what I do know is well be the lightest of all the DP cars currently out there. Next comes the helium balooons

32 and some change is the lightest Ive heard btw.... so If thats on par, yeah I think we can hit 3095, with the other 10 out and some other "tricks" The only option beyond that is cutting on the car, and that I will not do.....

A half a pound here, there and 6 ouces here 4 ounces there, well all total Ive got over 25lbs in "ounces" on my weight spreadsheet.....pretty interesting when you add it all up.

This is a very interesting thread.My next question is if you do all of this and you end up weighing more than you had hoped,do you think there should be a maximum overweight rule?
This should probably be a thread by itself.There was a discussion of this earlier in the year.My original thoughts were that it is unfair to the "heavy " drivers like me to penalize a car for being too heavy for a particular class.On the other hand,its not really fair for a car to run 1.2 under a new index and still be 2-3 hundred pounds over the minimum weight.What is your view on this?

[Chris "drooze" Wertman]

My view ? Ive got none, I will just run what the rules say if they are fairly applied My misunderstanding on the driver weight was it was an average applied, I failed to read the last line......it will be weighed with driver in. duh.....

Give me a weight with anything and will try as well as anyone to make it (assuming Im not 600lb overweight to start)......that Ill take to the bank, If I can do it on a bike I can and am doing it on a car....I WILL make the min weight with this car eventually I think, even if it involves things like alloy motor mounts (these things HAVE to weigh 20lbs +) as well as other things I can see already there is room for improvment. Weight is free power , power with the limits on Stock Eliminator I cant be too creative on the motor side. But the first step is to do as much as possible without banging deadlines to get the car tracking in the next couple weeks and then Pomona....besides....then I can put the weight where I want it. I mean come on , Roush used .075 steel for the heater delete ! dumb.....just dumb....Ive got to drill spots to get it out, but theres over 1 lb there that can be removed, even with legal steel in place, not to mention Im sure they used the same stuff on the trans tunnel and other places....

But if I can run fat and avoid getting HP added....yep Ill do it, if they change it Ill do what they change it to....Im pretty rule ambivilent. Ill take advantage of anything I can but Ill follow it all.

Drooze,
Thank you for this thread. I thought that's the way it was but wasn't 100%.

[Chris "drooze" Wertman]

Lol...thank YOU, yours was the one that made my brain scramble and figure out how far off I was....

Then the other filled in the exact details....

I love forums for just that reason....I would say "stick with me" but the others might bludgeon you when you werent looking if they thought I made a friend here

Sorry goes to another thread that ended badly.....and ugly.

But Im like gonaherasyphilits...not so easy to get rid of.....
