Increase speed without increasing HP?
What are some ways to increase speed without adding more HP (like weigh reduction or better aerodynamics)
what about increasing torque?

Re: Increase speed without increasing HP? (ir0nmaiden420)
increasing torque usually brings with it more HP, though if you mean increasing torque at a certain low/mid rpm then you can lose some top end HP as a result
and HP is where the speed comes from in the 1/4mi
I dont understand your question

increasing acceleration
almost anything else you do is going to move that power peak up in the band

Ah then, I agree; reduce weight. For example leave the spare & jack home and stomp on it with 1/4 tank of fuel in the tank.
Also more gears will increase acceleration, to a point. Of course you still have to hook it up.

Re: Increase speed without increasing HP? (ir0nmaiden420)
Since the formula for horsepower is HP=RPMxToque/5252, you cannot gain torque without increasing horsepower unless and equivalent loss in RPM happens that would compensate.
Also, vehicle weight has little to do with top speed but it has a tremendous effect on acceleration. 100 pounds equal about .1 sec in the quarter mile.

Re: Increase speed without increasing HP? (95AquaC4)
Reduce weight.
I removed front sway bar, A/C and pulleys, and stock seats.
My Racing seat weigh 15 lbs ea.
Skinnies up front will result in a loss of about 30 lbs per tire/ wheel.
Go on a diet! (costs less).
Better rubber in rear helps on lighter (racing) wheels.
These, along with all the above suggestions should help!

Could be wrong here, but if you want to increase top speed, I think you need to gain weight, not reduce it. Take you longer and further to get there though.

So making the 1/4 mile further would be a problem. :)

Re: Increase speed without increasing HP? (Matt383)
Most things won't increase your speed, but will increase your E/T.. which is more important IMO. Start with a rear end ratio that maximizes your engine's power band.
