Weight to additional speed

[wormdoggy]

Can someone tell me the additional speed produced by eliminating 1 lb of weight off the Vipers. In other words if I were to remove 400 lbs , how much additional speed will be attained say 1/4 mile or 0-60.

Just curious, I'm trying to figure out the correlation between weight and speed.

Cheers
Patrick

Obviously a general answer but I've heard approximately .1 for every 100lbs.

REALLY.............I would have thought it would be alot more. So what we are saying is that if stock is 3.7 sec 0-60 then by eliminating 400 lbs we are now producing output of 3.3 sec. 0-60. I'm just wondering since the car would be lighter if traction will now become an issue.

Very interesting. Thanks Chuck !!!

I think the .1 for 100 lbs applies to the 1/4 mile, not 0-60. I think it would probably be 1/2 of 1 tenth for 0-60.

I think the .1 for 100 lbs applies to the 1/4 mile.

That is the rule of thumb. 100# = .1 sec / 1/4 mile.

i have heard that for each 8lbs removed is like adding 1hp if this correct it works out like this


remove 400lbs is like adding 50hp

along w/ better handling & brakeing

Don't lock yourself into any of this stuff Wormdog. It's very general.
