Need an assesment of this

If my car weighes 3900 and it has run a 1018 what would a 2500 lb car run with the same combo theoriticly o No:

 

8.70s

 

I got about the same thing;

3900 lbs w/730 rear wheel HP = 10.18 @ 133.8 mph

Knock the weight down to 2500 and you get 8.78 @ 155 mph
(more or less :Brow: )

 

The old saying that every 100 lbs. is worth .1 seems to still be true.

 

Is that from a calculated guess or an actual formula?? Is there a formula??

 

I am having a discussion with a coworker about weight vs HP and et. so you know what the discussion is about.

 

Mike, I have one of those quick calculator things that is "relatively" close at times if you want to call and give me some numbers. I think the 100#'s per theory is a good one too, for slower cars. The faster you go, the less acurate I feel they are. Like Doug H and Rod H bustin' "theirs" to get into the 8's and 7's for example. If used as a basic type deal they are ok. That being said................Your set up in a light car, THAT CAN HOOK(lmao), I would say mid to high 8's depending on the track and such.

So who wins the debate at work ???????????

 

I've always heard a hundred pounds = a tenth as well. OK Mike...... You've sold the GS ragtop and now your askin' about 2500lbs cars. You gonna tell us what your up to??????

 

Finally A Chasis Car

I don't know if any of you saw the chasis car Mike was trying to sell at the Nats this years, the green and white one. :Brow: well even though it is not crhome moly I think he has found a way to put his motor in it. :beer

He will definitly need a full face helmet to keep the bugs out of his teeth. :3gears:

 

Ok so what about an 1500 lb car?? :3gears: :Brow:

 

1500Lbs? I have a spare scirroco shell with ground effects!!! :spank: :3gears:

 

Mike,

You need to get back to work on that house, or your green car. One or the other. Quit talking to the Ford boys and do something will ya ?
