Some people have so much power that they'll just spin their tires and ---- with a shorter gear ratio (EX or B16 tranny) But the answer to that problem is slicks, urethane mounts, etc. Anything to improve your traction.

Sure you could just get a longer geared (DX or LS tranny) and not spin the tires as much and you might be able to get better times with that, but you would get even better times with the shorter geared tranny and some improved traction.

no, if you have power like that you need wider gears. do you hear top fuel dragsters bang through 5 gears? its more of a ballance you have to maintain. if your gears are to short it will accualy make your car slower in accelleration. and not just because of traction issues. if you floor it and it takes you 2 seconds to get to redline in first and second (not spinning tires) you're putting down way to much power for thoes gears and waising time shifting that much. go play gran trismo make a 1000 hp car keep one at the stock gear setting and gear the otherone as close as possible and tell me wich ones faster.

You have a good point for super high HP setups, but for the cases I was talking about I stand by my examples.

Word.

An HMT setup (~200 hp) would suck balls with an Hf transmission.

I hear this statement allllllll the time. Funny, 3rd gear in the EJ sucked N/A. I get to like 9Xmph with boost and it's quick but just queer. 1st 2nd then 3333rrrrrrdddd. Shorter is always better. That's why we all win against Corvettes on the highway then we hit 140mph and they are going into 5th from 4th.

Re: Tranny opinion

Remember kids, your transmission gear sets are just unit multiplyers.

"But Mista Pimpsta, what the ---- does that mean?"

I'm glad you asked
look here,http://science.howstuffworks.com/gear-ratio1.htm

the jist:
short gears put torque to the ground sooner then later, long gears take less torque to turn(think gas mileage).

here are the "unit multiplyers"
i got these numbers from
http://hybrid2.honda-perf.org/tech/zcinfo.html

ZC: Si:
1st: 3.250........ 3.250
2nd: 1.944........ 1.894
3rd: 1.346........ 1.259
4th: 1.033........ .937
5th: .878........ .771
final 3.888........ 4.250

the ratio is in reference to gear rotation/crank revolution.

Re: Tranny opinion

my opinion is that if u have 450whp an ls tranny is perfect for a street driven car

Re: Tranny opinion

well that was a good read. i love that site they make it so even stupid people can have an idea. but i to have heard long gears for turbo but i was thikin if you get an ls tranny with a lightened flywheel it would pull threw the gears faster because of less weight to move right? and kinda equal it out.

and i have a y1 tranny and a gsr and i was thinkin about what jago said. is there that big of a prob that ill need to worry about when i boost?
