I've got a C5 Corvette with a LS1 motor, M6 transmission, using a 100 shot of dry nitrous. I have bought Motive 4:10 gears for the rear-end, (didn't put them in yet), but have heard both sides as to the effectiveness of using the two together. Some say it will work and some say that the nitrous doesn't have enough time to be effective because the 4:10 gears cause you to shift in a shorter amount of time, thus not allowing the nitrous to produce it's potential power. Anybody out there using both or have an opinion? Also, I do have other mods in the car such as LS6 intake, .589 lift cam, headers, etc., etc. Thanks.

 

i was told the same thing, you would be shifting to much, i have 3.90's but no spray yet, your vette is lighter and you also have a cam so maby a 3.73 or 3.90 would be better for you

 

I was going to change my gears also, but decided not too because of the spray. I decided to keep the stock 3.23's for now. Nitrous loves 3.23's. I'd rather save the money for a 12 bolt.

 

You'll need to run some taller tires out back at the track on the hose to keep from shifting to 5th in the 1320. Other than that, there's nothing wrong with 4.10s and juice! You just have to set your car up correctly to utilize what you have.

 

I don't have a vette, but I am running a 150 shot on 4.10's and "shifting too much" never really came across my mind. I do see where you're coming from though, especially if you're gonna be drag racing.

 

the gears will help you on the bottle, just like theyd help you on the motor. youre only concern should be running out of tire in the 1/4. besides, even if they werent "optimal" for nitrous, im willing to bet that 99% of the time you drive the car you are not spraying!

get a good set of tires, and cram it with as much gear as you can without having to go into 4th in the 1/4

 

My Z06 has 3.42's, but with the M12 the effective ratios are
1st-3.82
2nd-3.98
3rd-3.76
4th-3.42
This is one the reasons the Z06 is faster from the get go compared to a standard C5. Yes, shifting comes up much faster on the spray. I have run a shorter tire than stock which lowers the gears even more and have never come close to running out of 4th gear. So, like has been said, if you are running out of gear with a stock tire hieght of about 26 inches, try a 28 inch tire, however, you may need to take the liners out of the fenders cuzz they will rub with a 28.

William, you mean without having to shift to 5TH

 

thats the dumbest thing ive ever heard.....screw stock gears go 4.10s

 

you should be fine with the 4.10. I have 4.30 gears and have switched back and forth between my 26" slicks and my 28" slicks. With my 26" slicks I would hit the rev limiter at 7000rpm just before the end of the 1/4 . With the 28" slicks it made a full pass with out hitting the rev limiter. The 4.10's will drop the rpm even more. You will be fine as long as you 60ft. good

 

Ditto with the others. Im on 4.10 and juice, works fine for me! get some grabbers on the back. either way, without stickies on or off the bottle, 1st and 2nd are worthless with gear behind ya.

 

Has anyone running N2O had to shift into 5th gear in the 1/4 using stock tire height? That would be interesting to hear about...

 

i had to once, with my 4.30s on a stock sized mt drag radial. Car went 11.4 @ 127mph on a 1.77 60'

there's an in car vid of it on video.ls1tech.com under my name if you wanted to see it for whatever reason

 

Spray on the 4.10's and hang the **** on

 

There is no reason it would be an ineffective combo unless you couldn't hook up in which case you shouldn't be making that much power in any form. Saying you have to shift too fast for the spray to be effective is like saying making power in boost is ineffective because you have to shift so fast. The nitrous doesn't have a time delay. When it's there you're making power.
Set up your suspension, get some fat tires, and spray away!
Edit: Check out this video. This guy is making 400+n/a and over 600 with dual stage nitrous setup. 4.56 gears. Ran a 10.42. His suspension isn't even set up for drag which is why it bounces down the track.

 

3800stall+125shot+4.10's=500hp of me

sometimes i wish i had a stick.

 

you also realize that naz has a built dohc motor and turns 8000+rpm, he never has to worry about running out of rpm to stay in 4th

 

Yes, I realize this. This guy wasn't referring to running out of gear though. He simply thought the nitrous would be ineffective because he'd be shifting so fast.
Naz was just an example...and a wicked one at that. Makes me want my '01 back *puts on flame suit*

 

6200 rpm revlimiter 4.10 gear 245/50/16 can only trap 115mph or 117 with a 26"

 

sorry, you put the 4.56 in bold and used a dohc motor as an example, just thought that was weird as these cars shouldn't be set up the same way(those cars have to have a high gear to make up for the lower hp/tq). as long as it can still hook, yea it will be (a small margin) faster. he really needs to think about how high he wants to spin his stock bottom end. i personally don't want anything over 6500rpm with the stock rod bolts. if he doesnt mind turning 7k then the 4.10's will be perfect for his setup. if he ever adds heads or a bigger shot(and odds are he will up the shot) he will have to change gears for sure or try to fit a 28" tire. a 3.90 will be great for that as he would have a little growing room. i'm going through that problem now, got my 3.90's sittin in the garage

check out the new gmhightechperformance there is a black t/a that runs 10.5's n/a with the stock bottom end, no built motor or two stages of spray
