please accept or reject this theory:

i have 426 to the wheel, say roughly double the power over stock. would a 15lb. weight reduction in my car feel like a 30lb. reduction in a stock car????

just wondering because i just weighed my tonneau cover at 11lb. and i figured if i took all the brackets off that'd be about another 3 or 4 lbs. its purely cosmetic and serves no purpose unless the hardtop is off and i am contemplating taking this sucker and and trying to sell it for fund preformance. having the CR, there arent too many items i can strip without ruining the DD ability and comfort it has now.

ANY INPUT IS GREATLY APPRECIATED

 

Interesting theory, but I'm thinking it's the same. 15lbs is 15lbs regardless of the whp you are making. The rule of thumb is for each 100lb's lost, you gain .1 in the 1/4.

Not set in stone, but a general idea.

Reminds me of the old saying, which weighs more, 50lbs of rock, or 50lbs of feathers?

 

Let's say your car is 2900 pounds and 426hp at the wheels, that is 6.8 pounds per wheel horsepower. Every loss of seven pounds will feel like one extra hp.

Will you notice a loss of 15 lbs or about the addition of 2.2 whp? Probably not.

 

^ dead on bro.

weight lost is weight lost my friend.

reminds me of a hilarious dude i used to go to "test/tune" night at the track with.

the damn dude wouldnt eat all day and would minimally drink enough water so that when he got to the track, he could "have that advantage". lmao

he used to ask me to hold his wallet and would take his car key off his key ring too. gotta keep that weight down!

he was nuts!lol but when youre 17 in a stripped out hatch w/gsr swap, i guess you gotta get what you can get.

Worry about dumb stuff like weight when you're racing for money. Don't beat yourself up about it otherwise

 

yea i just read the thread in the racing and comp. forums and saw some of the weights people are getting their s2k's down to

 

Every 100 lbs lost is typically 10 whp gained.

 

The more power you have, the less the effect of removing weight will have on the power to weight ratio.

Example:

1000kg car with 100kW engine. 10kg per kW. Remove 100 kg, power to weight ratio is now 9kg per kW, an improvement of 1kg per kW.

1000kg car with 200kW engine (twice as powerful). 5kg per kW. Remove 100 kg, power to weight ratio is now 4.5kg per kW, an improvement of only 0.5 kg per kW.

So, removing 15lb from your 426WHP car will feel like removing 7.5lb from a 213WHP (close to stock) car

 

It's based solely on percentages. Taking 50lbs away from 210 hp is not the same as taking 50lbs away from 450 hp.
