Overcoming the draglimited

[Phreak0402]

I have a 01 V6 accord auto and I was wondering if there is anyway to overcome the drag limiter. cause it really sux

yea, just break all laws of physics... drag is caused by the car trying to push itself through the air, the accord while fairly aerodynamic is by no means a mclaren f1, with its huge side mirrors and somewhat tall interior.. it is drag limited to about 140mph,

ive heard several different things, but i think drag doesnt really come in as a factor until about 120mph, you shouldnt have to drive that fast anyways

I think he might be talking about the rev limiter on the engine or the speed limiter. No you don't wanna get rid of your rev limiter and as far as the speed limiter, a computer chip or having your ECU reprogrammed will take care of that.

I was refering to when I hold it in 3rd to the redline then after going up to about 128mph, the tachometer goes down to rest at 3500 rpm

[Phreak0402]

thats after shifting into 4th after redline'n 3rd

Once you get passed about 40 drag becomes a major factor. Think about it my 'Stang at the drag strip hit the 1/8th mile going 71 MPH on my best run, the next 1/8th I only got up to 89 MPH, all I was doing was pushing air out of the way. Air drag increases as a square of the frontal area of the vehicle. The only way to overcome it is more power.

you also only got up to 89 due to different gear ratios (im assuming you shifted sometime), not just air resistance

for what purpose are you going this fast?

[Phreak0402]

the only purpose I have for going that fast is testing out the mods I have done to my car to evaluate how effective they are. whether it be evaluating the acceleration or the top end speed. It just really gets to me sometimes that 4th gear is practically useless in my car. cause where I get it up to in 3rd is pretty much how fast the car will go with the exception of creeping up a few MPH in 4th when it levels it self off at 3500rpm not too long after shifting into 4th.

For a solid body the drag is:

Drag = Constant X velocity^2.

The constant is related to the crossectional area and shape of the body and also the properties of the fluid the body is traveling through (in our case, air). The drag is proportional to the square of the velocity, though, so doubling your speed in effect quadruples the amount of force exerted by drag. That's why your mods might help you out 0-60 and in the 1320 and not make much difference at the top end.

Well the reason your car wont get beyond 3500rpm in 4th is because of either 2 reasons, lack of power to pull your overdrive gear and/or aerodynamic drag. One way to overcome that is HP. Power has the ability to overcome drag to a certain extent. Its easier to do aerodynamic mods if air drag is your problem, but power will do it too. Odds are its a little of both. If you had less aero drag, then your engines power wouldnt be consumed by aero drag and it could go faster. You have an Accord, its not mean to be top end fast, thats what Corvettes and other sports cars are for. You have one of the best selling family cars in America. If you want top end fast buy something sporty like a 'Vette.

The 3rd gear ratio does kinda suck, 1 and 2 are nice and low, I hit the redline in 2nd just below 60 and then it's a long ass climb through 3rd. Only one answer, more power or change to a 4.10 gear

The Accords the daily driver so fuel economy is not a concern.

Edit:Gear ratios 2nd gear is 1.99, 3rd is 1.33 Rear end ratio is 3.73

So we go 7.42 to 4.96 going 2nd to 3rd. 4th is 1 to 1 so its 3.73. Big jump between 2nd and 3rd. 4.10's would make 3rd a 5.45 total reduction. Too bad it costs $400.00 to change out the gears

I am quite aware that the accord is the best selling family car, but I am just trying to make due with what I have. I am not expecting it to compare to a vette. I got an 04 GTO with a Gen III LS1 5.7L, thats the one I am looking to get to compare to a vette. I just want the accord to be all it can be, but ofcourse money is definatly a factor in that.

[Phreak0402]

by the way, check out the 04 GTO, its a beast for a car that it is. powerbrake, and spin the tires up to 3000rpm, release the brake and let her rip!!!! :clap
