4.10 / 4.57 / 4.77 gears whod win to 110?

I can't decide whether to get gears done or not. I like that fact that you have more power in the beginning but from what I've been reading 4.10 will catch up to you so to me seems pointless. Lets say al drivers were equal who'd b the fastest?
Give me your opinions.......

4.77 > 4.57 > 4.10


You would be way to far ahead with the gears for the stock to ever catch up with let alone pass.

i agree. someone should post the gears vid. hot tip:before you see that vid lock up for credit card.

i've really wanted to see a video that shows 4.77's against someone who has 4.57's

+1 for the vid

Its a ~4% difference in gearing.

Most likly, it will be a drivers race between 77s and 57s but theoretically the 77s should win. But then again...stock s2ks beat C6 Z06's in our street encounters forum

Do what? What idiot actually trys to convince himself that a s2k has any chance of beating a c6 z6 lol. That thing can take us in reverse.

On Paper the race is closer than the video

LOL, I'll race for money if the C6 Z06 runs in reverse.
(Not on the street though. )

Actually, I'm of the opinion that anything can (and does) happen in "street racing," so I'd be slow to call someone a liar. Back when my car was stock except for an AEM V1, Tripper Cooks R33 was making 400 WHP, so there is no way I could have outrun him ... And yet that's exactly what happened. Tripper made the common street racer mistake of letting someone suck him into a situation where they had all the advantages and he had none, and that kind of thing happens on the street all the time. In general street racing results tell us nothing other than that the racers may be missing a few of their marbles.

I didn't change my gears until after I had forced induction, so it might be different with an otherwise stock car, but with the 4.30 gears my car pulls harder (as measured using accelerometers) all the way to redline in sixth gear, so I'm wondering when a supercharged car with stock gears is going to catch up.

Actually, if you overlay the acceleration data you can see that the stock gears did produce slightly better acceleration at the top of each gear, because I have to shift sooner with the 4.30's, but the area under the curve is greater with the 4.30's (IOW, the average acceleration is higher across the speed range).

In my old X-1/9 (which also turned 9k RPM) I replaced the stock 4.11 gears with 4.88's, and the gears transformed the car.

Do you autocross, track the car, or drag race?

If the car is supercharged with the stock gearing its going to keep up and pass you no matter what gears you have all else being equal.

Its said that 57s / 77s can KEEP UP with a SCed stock geared car till somewhere in 3rd gear. That doesn't mean it will outrun it though.


However gears being ~1000ish and a SC being ~5000, they are a pretty good bang for the buck


Oh and I was being sarcastic about the Z06 if no one had noticed

these are the links to those videos:

Im reallt eaning towards the 4.77 that motoclasse has but I've been doing so much research that everyone has a different opinion. Anyone do a 1/4 mile run with 4.77 gears please post your numbers and your mods.

but tanks for the discussion keep it coming.

Can someone do me a favor and post links to a direct download of those videos (if one is available) I am at a client site and they have one of those programs that block pages labeled as multimedia content.

First I would like to say I have not ever driven a 4.44 or 4.77 geared car.
The 4.57r I know by now.
Just this morning I was thinking how much more "driveability" the car now has with the 4.57 gear set.
It accelarates so easy, also in 6th.
While at the same time the revs are still relativy low, even at highway speeds of 130 km/h (82 mph), just cruising, a nice purr from the engine at 5000 rpm.

And instant acceleration at demand.

All I can say I like 'm verry much.
The S2000 should have been made with such a final drive.

Read my post again, and look at my signature. There is no way a Comptech supercharged car with stock gearing is going to keep up with my car with 4.30 gears, but you missed something important.

If you read the post carefully you'll see that in the very part you quoted I mentioned my supercharger, and I've also got an FI badge in my signature. So I'll repeat the question. When is the supercharged car with stock gears going to catch up?

(The answer is, "After an extended period of time traveling in excess of 160 MPH, and I don't know any place where that's possible." )

Anyway, you're right about 4.57's being about the same as SC up to about 80 MPH, and a lot cheaper to boot. With just gears the car with lower gearing (higher numerically) is going to be quicker until it tops out, then the car with higher gearing (lower munerically) is going to start catching back up (assuming all else is equal).

I haven't tried anything but the 4.30's, but I think anything lower (numerically higher) might be too low for autocrossing. I can still run the slower courses without shifting, and becaue the slow courses are always so tight and busy not having to shift is important (at least to me ). On more open courses I have to shift sometimes when I would not have had to shift with the stock gears, but since the course is more open and less busy it's not a problem. For me at least, with the SC/AC, I'm sure 4.57's would be too much, but I believe that will also be the case with a stock motor.

Have any of you autocrossers tried 4.57 gears?

For street use with a stock motor 4.57's look like the best choice to me, and I believe the 4.57's are stronger than the other ratios. If I wasn't FI and didn't autocross that's the way I'd go.

that's a hell of a difference! now i want gears damnit!

too late I saw the vid already and did't lock the credit card.

ahhhh sorry about that, I see what your saying.

Now to answer your question correctly, a SCed s2k with stock gears is (IMO) never going to catch your car. Basically your correct, the only real time is when you max out your speed and the 4.10s max its speed up...then it can slowly creep up and pass you

57s a great for the autoX (I've done it) but like anything there are times they arn't so good and vis versa with the stock gears.


Most autoxs I've been on you stay in 2nd gear pretty much the whole time (they are low speed track setups usually at Etown). Occasionally you'll be at ~3-4k rpms in 2nd for a second or two, the 57s give you the down low torque you need to accelerate back into the powerband.

They are definatly great for autoX



I'm getting a SC at the end of next month and I have the 57s. Should make for a very fun time



If anyone wants to, search for my impressions on the 4.57s. I've recieved many PMs saying how informative my post was. Might do everyone some good on how great the 57s are.

Again, can anyone pleeeeease post direct links to the vid's so I can see them here at work. Can't go to the site officially but I can link to the movies directly to download if there is such an option on the page. I don't want to have to wait until I get home, that's just toooo long and I'm toooo bored.

4.77s will rock your world. buy them.

yes they will. Get them and don't look back
