Trying to reach top speed (gearing questions) HELP!!!
Hey guys, I have a mugen mrx3 that I drag race with a few local guys every sunday. I'm just wondering if someone could point me in the right direction to achieve top speed in my car without losing too much of the bottom end take-off. right now I'm running a 18/22 pinions and 45/49 spurs. I'm running a Falcon .21 modded race motor if that helps any. I know my car can go faster than it is now, any and all help will be appreciated.
Thanks,
Thanks,

top speed
I didn't think that the mrx3 had a 22 pinion but anyways, do you have a certain distance you guys are racing or is it unlimited open asphalt because the gears you are running are the highest pinions and the spurs the 45 is the highest and there is a 50 for first gear spur. you are geared for the fastest that that car will go but it will take you a little time to reach it with that gearing. so if your limited in the distance you have to gear down also the size tires you run can effect how fast the car the car can go and how quickly. I would try 17/49 and 20/46 you will be much quicker and your top speed should reach 65 with no problem. don't forget the importance of the clutch,

Oh, and will taller tires give greater top end or will they need to be trued down.

testing
as the tires wear down you could change gears to keep the car going the same speed as when your tires are big with smaller gears. the best way to get the most of your car and the what works best is to do alot of testing and time all your test. lets us know your measurements when you get a chance
