first time at the tracks..didnt do too well =/
2002 Honda Accord Sedan 5speed
my best times was RT: 0.95 I1: 2.64 I2: 7.142 I3: 10.830 MPH(I3): 66.999 I4: 14.046 E.T.: 16.778 MPH: 83.179 this is with a low rev launch..and when i tried different launch points from 2.5k - 3k and 3.5k .. everytime i would bog and stay in the trap zone to long and one time at a high rev i popped out of gear! this is my first time at the tracks, and i just went for fun, i know my car is NOT fast, i went with my friends who have fast cars, and just wanted to join the fun..what are your insights on my poor numbers? my car rated stock is suppose to run 16.1 so i didnt do too bad right? but i do have basic mods like intake and cat back exhaust..my friends say, its my tires/rims, i bought the car used and it came with these huge 18" kyowa racing rims..they say when i get smaller rims and better tires we should go again..what do you guys think? |
Huh?? :confused:

Get smaller rims and tires. Try 15". Here, I found this article online. I couldn't have said this better, myself.
When factory-calibrated tires are replaced with larger tires and rims, a car's transmission will continue to run at the same speed. Larger wheels will make fewer rotations than smaller tires. This means, as the transmission continues to clock a specific speed, larger tires will actually cause the car to move more slowly than the speedometer reads. Depending on the increase in tire size, a car will usually travel about 5 to 15 percent slower. The opposite effect is realized when smaller tires are installed. |
That time is pretty bad. I managed to fling my autotragic Accord(VP and stock) into 16.9ish at the 1/4. It boils down to the launch to be honest. Replacing the wheels will help quite a bit as well. Larger wheels will weigh more as well as other random physics stuff that will work against you when it comes to larger wheels.

For steady driving, larger wheels will make the car go faster - more accurate to say they'll make your speedometer read low. Larger wheels/tires will put your engine at a lower RPM, likely results in slower times. |

That's backwards... Where did you find that article?

guess it was my rim/tire combo, thanks everyone for the feedback
