Got my 4.77s from HTG as well.

 

Here is my thread that I wrote about my impression of the 4.57 gears (that Ks320 was talking about)

gears

 

I think everyone says 4.57 are the best because that's what they have. It depends on what you want to do with the car in the end. If you're staying N/A, I think 4.77 are best (what I have). If you're going to boost, I think 4.57 are best (I wish I had 4.57 now because I'm going turbo). 4.77 on N/A cars makes your acelleration down low INSANE! You are WAAAAY faster than stock S2000s. When I run a stock S2000 in the first 3 gears or so, the stock one is a complete joke. You absolutely trounce on them. With 4.57 on a N/A you just feel "a little more oomph".

This is for AP1. For AP2, I think 4.57 would be best for N/A, and 4.44 is best for boost.

I got my 4.77 gears with Comptech differential through Hardtop Guy. I paid around 1350 after I got my 1000 dollar core charge back. If you're staying N/A, get them, you will not regret it. Or, buy a Comptech differential with the standard 410 gears and I'll swap with you + cash

 

if you are into quarter mile racing, the 4.77s will require a shift into 4th, which will slow you down. I think 4.77s will make you faster, but 4.57s will be faster over a quarter mile. Confusing, huh?

 

Yeah, the primary downside of the 77s is that you have to shift more which is apparent in the 1/4 mile -- its about as fast as a stock s2k.

The 57s are quicker then a stock / 77 because they don't require the shift (like the 77s) and they are quicker then the 4.10s by a decent amount.

 

You guys are insane. The 4.57 tops out at the end of 4th gear. The 4.77 requires the shift into FIFTH gear. Still, the 4.77 is faster. There is no "seed of doubt" here. They are faster in a straight line, end of story.

I'm not saying they're faster because I own them and want them to be the best, as I already stated I'd rather have 4.57 or 4.44 now (or even 4.10 with CT housing!) because I'm going turbo. However, they are faster than 4.57, and ESPECIALLY 4.10. Spec ops I have no idea where you got that thinking that stock gearing is even with 4.77.

How long does a shift take for a quick shifter? There is NO WAY that a car could catch up the additional distance that the 4.77 car put on them during the time it takes a quick shifter to shift.

Period.

I could put a buslength or two on a stock geared car with my car as it is now. If I'm, let's say, 40 feet ahead of another car, do you think they're going to catch up 40 feet and pass me during the time it takes me to shift into 5th? Nope!

Here's where 4.57 excells: When you are keeping your car next to stock, with bolt ons, where you will never trap higher than 103 or so. Once you start really "making the car faster" (internals/FI) you'll end up with a higher trap speed and require the 5th gear shift anyway. So, if you want to be running high 13s for the length of your drag racing career and you're not that quick of a shifter, then by all means, get 4.57.

If you want to be a stoplight racer and really pull on people in the early gears, 4.77 is the gearset for you. There is nothing like feeling a 6000 rpm roll on in 1st gear with 4.77s. You'll waste everybody.

 

The general concensous is that the 77s are about as fast as stock (probably a little faster) in the 1/4 mile because of the extra shift.

Overall, no doubt they are faster then stock and will definatly pull on one. But for the 1/4 mile your only a tad faster due to the shift.

Its also not that ONE shift into 5th. Its that your overall shifting more and sooner then the stock car is (since it can go longer). It all adds up.

I'm not putting them down eithor, just stating what I've read from the street encounter forums --- I don't have 77s so I'm not comenting from personal experience

 

I know you're goign by the general consensus, but the general consenus is that Comptech makes a nice exhaust system. That doesn't make it true!

The bottom line is that, there is no way that a stock geared car is going to keep up with the 4.77 car. It's just not going to happen. Yes, you shift sooner. Yes, you shift one more time in a 1/4 mile race (who bought this car to 1/4 mile race exclusively anyway?). Still, the 4.77 is faster than the 4.10. It's even faster than the 4.57. People advise to get the 4.57 because you don't need the 5th gear shift in the 1/4, and they're more "streetable" because you're not all tached up on the freeway.

If you want to get gears and have them in moderation, being "a little faster" or want to spool your turbo or SC sooner, they're (4.44 or 4.57) great. If you want your car to have huge balls, and be able to waste all the kiddies at the street races then 4.77 is the way to go.

I'm speaking from experience as I've driven stock, 4.57, and 4.77 personally.

 

that extra shift means you are in the lower part of the power band (7-8K) more often. So, from a "cumulative horsepower" perspective, that's bad.

The more time you spend in the high part of the powerband, the better.

 

I have an AP2 & want to do the gears. Most of my driving is in town with weekend trips into the hills. are the 4.77s going to kill my driving at 90mph+ as far a sanity is concerned of a screaming engine? what are the respective 70mph rpms of 4.57 to 4.77 geared cars. I will never do forced induction FYI
