Please can someone here put an end to the debate that longer gearing is better becuase you stay in boost longer.
Im soo sick of hearing of this knowing that . . . . well in my eyes makes no sense what so ever.
So can someone please vouch with their experiences.
Pereferably like Viren , Tony, and all the other fast ***** on this board that actually know from trial and error and have a good sense of knowledg
maybe make it a stickky to put it in stone to end the debate.
Their are too many young heads that seem to think the wise tail of longer gearing = better
and shorter geargin = bad

Noooooo! Must... stay...... in ..... booost...... longerrrrrrrrrrr!!!!!


Seriously though I'm boosted with an ITR tranny and loving every minute of it. Just wish I had a taller 5th.

PM-Performance

see i dont evenknwo if id change out the 5th becuase then it throws everything off. . . i know when my R was NA all the gears pulled hard and thne into 5th i thought it was kinds laggy until i got the rpms bac kup . . . i think 5th is just right for that car, if not a little on the laggy side.

but we shouldnt be creating boost in 5th anyway right?

i actually thought the reason for useing a car with longer gearing was not to stay in boost longer but so you can finish the 1/4 mile in 3rd gear. with my type r tranny i shift into fourth bout the 1000' mark, with a ls tranny and a taller tire you can run out third gear till the end. sorta why the consitant v8's use 2 speed power glide transmissions they one have to shift once and that leave less room for error. reguardless im keeping my type r tranny.

I think the GSR tranny sets it just right. Just depends on if it's an everyday driver or a race car..............race car=b16tranny
street car=b18btranny.........the debate will never end because of different peoples opinion. We need to just Brain wash.

THE BOTTOM LINE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


for drag racing: you want to go through the traps at your peak power in 4th gear on our cars......using tighter gearing along with a larger tire size, higher rev limit and/or even multi staged boost is best. LS tranny is ***. period, end of discussion.

for highway/top end speed: LS tranny is the way to go.

PM-Performance

exactly, thats what i think they get confused about .
shorter gearing for 1/4 mile . and longer gearing for top speed and highway racing .
i think its almost cut and dry in these apsects. i mena it can get much deeper than that , but for the most part, you brokit down.

Smashback

this is the same gospel i preach

LS tranny is total *** in dragging. The gear u want is either 4.4 and higher fd with a short gear set.

I prefer b16a over all jusy my opinion wiht 28*10 slicks easily gets you in the traps over 150mph in 4th at about 8500 rpm

even on the highway the shorter geared tranny would own an ls tranny..well up until 140 when your all out of gear..its beyond that,that you would want an ls tranny(if you wanna go faster)

jinxproof99

if you intend to have a set up for top end runs, 140 mph isn't gonna cut it, thats why you'd have to have the LS tranny. we're talking 170 mph+.

ahobbs

that's absolutely right. The ls tranny would lose at first on the highway but kick 150+ when the b16tranny can't catch up......diagnosis=b16tranny with ls fifth gear

I have a GSR tranny on my B16T. I am well into the powerband pulling hard in 4th when I cross the 1/4 mile marker. This is on my stock (14") Firestone all seasons and untuned (best 1/4 in sig).

That's it, plain and simple. Figure your tire size and expected mph in the quarter and pick your tranny from there. I've yet to see a honda that makes more power at 5.5k then it does at 6.5k, so there's no point in falling any lower between shifts...

I thought we ended this discussion a long time ago. I don't want to have to repeat myself! Everybody listen and learn, this is how it is!

Smashback

Tony, we have to start a support group for people like us...whenever anybody talks about taller gears being better for the 1/4 I want to go The Shining on their ***!

Nine

Lol, who here really has the ***** to debate a guy with an 8 second 1/4mi in the first place...

tony1

The people who believe the longer gear bs are the people who believe everything they read on the internet and then tell all their friends that's how it is. Those people need a support group all together...

Realize that alot of what is on the internet is not true, I just don't have time to argue with everybody

bambooluv

hmm that dosent leave me to much of an option on the prelude trannies, I have a couple si's that Im getting but will change out the final (pending funds) to the h22 finals which is the only difference from what im told between the two.-pdang

wHOAlly

yea, unfortunately its called honda-tech

of course thers a small select group that know WTF they are talkin about, but then thers rest...."the masses"

plain and simple, a gear is a torque multiplier.

The higher the number (and thus, higher mulitplier), the shorter the gear.

A shorter gear will always out accelerate a longer gear, all else remaining the same. Fact.

For the street, consider drag radials, differentials, traction bars, and staged boost as the correct way of obtaining traction. Using a longer geared tranny is like reaching over your shoulder to scratch your *****.

If you want the sick top end, drop a LS 5th gear in like I did for my GSR/B16 tranny.

swlabhot

LOL!! Ha-ha-ha !!

simple4012

interesting.....i never thought bout that. But i think with short 1-4 gearing id bog real bad because of the drop.....good idea though

PM-Performance

exactly, thank you .
IM glad these people chimed in becuase like someone else said , whos gonna argue with someone who runs 8's, 9's and Jinx who did 10's with a street car. . . i mean cmon , they did the research they have tried diff set ups and got their hands dirty. . . these other guys that make up these falicies, quote **** from something some stupid kid posted on the internet a long time ago .
thanks guys, i will bookmark this page.

ahobbs

ITR206....I THINK YOUR WISH CAME TRUE. No one can argue with a guy that runs 8's.....i wouldn't. I guess that's why he gets paid for doing what he likes and damn good at it! for TONY!

The misconception of staying in boost longer is only a resulting observation from using taller gears. How you say that you'll be boosting longer when it takes you 1 sec longer in the taller geared transmission to hit boost. You should be in boost from then on until the end of the run.

It shouldn't be an issue of ITR vs. LS tranny because a real drag racer knows that it's close ratios rather than merely short ratios that you want. The ITR final drive is so short that it brings the effective gear ratios closer together. The LS final drive is much taller, but it also has taller upper gears too which exaggerates it's wider gear spacing. However, If you have a really short first gear, what good is it if you don't have the traction? After all, the most accelerative force you can get is right before the wheels begin to slip, right? Assuming as in a high powered vehicle, a taller first gear allows you to better balance accelerative force with grip. Then, if you can get the same accelerative force with a taller gear (remember, the shorter geared setup will be slipping) you be shifting at a higher speed and further down the track. Now the trick is to choose gears that would complement that taller first gear by keeping the engine near it's power peak. Obviously, a launching with a turbocharged engine will complicate the setup, what with the additional objective of getting into boost sooner, but the concept is very similar.

As for some of the domestic V-8s running a 2&3-speed automatics, the torque converter will function as a crude CVT, allowing the engine to spin at higher rpm's where it makes most of it's power, but converting that power into higher torque at a lower rpm at the input shaft of the transmission. It's wasteful of power in the long run, but the torque multiplication (giving greater acceleration) seen over a quarter-mile run will more than make up for the inefficiency.
