Hondas no matter how stock they look always have something hiding in the engine...wouldnt be surprised if he had a cheater shot...gsedan is right vdc helps, so does having a 6mt, remember the B&B exhaust makes its 8.5 hp at 5100 rpm so you get nothing till then, you might actually lose a couple before then in the lower power band...get some test pipes or free flowing cats popped in along with some Xerd headers...

I also have an AT coupe..i raced it at english town and got a 15.7 the first time..i realized that the vdc was on and i turned it off and got a 14.87 the second time and a 14.6 the third...VDC ALWAYS OFF BEFORE A RACE...also if you have time release some air from back tires for better grip..good luck!!

 

everyone is telling you to turn the VDC off and they are right, but if you have never driven with it off before (especially around corners) be carefull. I drive with it off all the time, but I know all of the slick pavement and corners around my neighborhood, which is a must with this car. good luck.

this is true...with the vdc off the curves are more dangerous specially if wet out

 

20's will definetly make you slower, at least 2-4tenths slower, and that is certainly more than half a car length. Plus it sounds like you didnt even power brake? You need to floor the break and gas and when your ready, let up the brake and those tires will spin..Trust me. You should have killed that car.

you should have killed him did you use the MM mode on the car when you were racing him? Dont trip he was happy he beat the G. Next time its a different story. Hope you spank him the hnext time around

Tfasano, can you explain to me why 20" wheels will make you slower? I don't think it matters if the wheels are 15" or 20" as long as the tire diameter is the same as the stock tires. I hate it when people say that 20" wheels make the car slower just because of the size. If your explanation involves the weight of the wheel then I will tell you now that my 20" wheels weigh less than the stock 18's".

I have read on several forums that you loose time for each additional inch. It doesnt matter so much the weight as it does how far the weight is from center. Theres no need to get angry and call me a hater. 20's arent for me. I can see your frustration though.

Sorry I brought up the 20" wheel thing and started a whole new debate. Don't forget to add the weight of the tire - there's a lot of rubber on a 20" wheel, especially if you are running wider tires.

Its a fact that 20's will slow you down. How much is open for debate and it might not be more than .3 - .5 in the quarter mile. Go to the strip some time and see how many competetive racers are rolling on 20's. I am not bashing on 20" wheels so don't get me wrong. They make a huge difference in appearance and don't hurt performance that much.

A bad launch and VDC on is what caused him to lose. They only raced to 60 so its all about the launch. If they would have had space to open it up he would have started to pull on him.

Sorry, I don't mean to keep this going but there is actually less rubber on a 20" tire than on anything smaller if they are the same diameter. The reason that people don't use 20" for drag racing is because the tire doesn't have enough give to it and therefore you won't get a better launch. Thats why drag cars have the tires with the most sidewall possible to be able to transfer the torque to the pavement more efficiently.

The less rubber on 20" isn't exactly true... But I do agree you can have lighter 20" wheels than the stock 18", also that more sidewall gives the tire more give.

If you have a wider circumference on the tire, and wider tires (due to wider rims), then it will equate to more rubber. Just because the 18"s are smaller size doesn't mean that the sidewalls cover the same area as the entire area of the 20"s with tires. Get wht I'm trying to say?

The increased moment of inertia is what slows you down with 20" wheels. The moment of inertia (I) is somewhere between I=1/2*MR^2 and I=MR^2 for a wheel, where M is the wheel mass R is the wheel radius. So if you increase the wheel radius, the moment of inertia increases exponentially, which slows down your car.

 

Hmm, looks like I was wrong about tire weight. I looked up some specs (Toyo T1-S) and a 285/30/20 is almost identical to a 245/45/18. Factor in the relatively heavy stock 18's and I would agree it is possible to save a little weight or break even with a set of quality 20's. Regardless, I am sure everyone with 20's is very happy with the look and ride. Enjoy your car and I apologize for hijacking this thread.

DragonGcoupe, I was refering to the tires being the exact same width. Of course if the tire is wider you will have more rubber and more weight

Paul1082, Your explanaition sounds great but when you take the wheel mass and the radius into question, don't you have to consider the whole spinning mass and radius, meaning the whole wheel and tire. If the wheel and tire diameter is the same between the 18" and the 20" but the 20" wheel is lighter, making the whole spinning mass lighter then wouldn't the 20" be better? If the 20's have wider tires, shouldn't it be better for traction.
I should be the one to apologize for highjacking the thread, but I am just trying to understand this whole concept. Please be patient with me.
