Power to weight ratio...

[Sp33dyF1sh]

Have a general question if someone would be so kind to answer or point me to the right link.... With the new challengers being so heavy.... 700 hp seems to be the "sweet spot" many ppl are going for.... Now my question is in the old chally/ cudas how much hp would they need to be equal(ish) to a modern challenger w/ 700 hp... Just based off of power to weight ratios.... If that makes sense..... Would it be more, less, roughly the same?

simple math if the new chall is 4200 lbs with 700 hp , you have 6 lbs / hp
so 3500 divided by 6 is 580 hp

Darn.....I am 50 hp short with my 440.  I quess its time to Stroke it.   

It's eaiser to drive a new Challenger with 700 hp than it is to drive a 40+ year old car with 500 hp.

But, is a new Challenger only 4200 and is an old Challenger only 3500? I've seen a few 3800# E bodies in my day.

my 70 440 4 spd R/T SE weighs 3500 , I have weighed it , my 74 360 4 spd was 3800 after removing the extended bumpers & reinforcement bars behind them as well as any other excess weight I could eliminate !
Same with the new Chall , depending what options etc the weight would vary so just going on average weight ....

ain't that amazing, my '70 Chrysler Newport looks twice as big as the new challengers, but only weighs 3950#

Nice!

Just going off the curb weights shown on Wikipedia, and edmunds and several other sources... 570-580 will roughly give u the same "performance" as a 700 hp 2014 chally

Roughly... Not exact obviously weights may vary and hp to be adjusted accordingly

But even the hellcat doesn't achieve 700 hp.

None of this takes into account the amount of power lost in the drive train in old cars Vs. New cars, ability of suspension to put that power down the ground, contact area of tires etc....so for performance to match it would be not just the power that matters but 40 years of evolution.

So even if you mached a new chal vs and old one in power to weight ratio the new ones power delivery is still going to smoke the 40 year old plus tech in the old ebodies. 

Still rahter have an old one!

I would have to disagree, IMO..... And if your gonna go ahead and shoot for 5-600hp in a classic anyways, your either going to have to, or might as well beef up the suspension and everything to handle the power... And while it may be case by case basis, I'm confident that old and new can be fairly matched...

Not a perfect example but still an example nonetheless
