rear end gears do not change horsepower whatsoever, it changes the rate the tires spin compared to the engine rpms either increasing acceleration and lowering top end or increasing top and and lowering acceleration js
This is the second time I have heard someone say this. To my understanding after doing some reading the lower gears will show a higher torque reading on a dyno an lower hp than the same car with a taller gear. Torque an hour on a dyno usually cross paths at 5250 rpm where torque drops off an hp climbs. This is new to me but that's what I've read so far.
Because when you change the rear axle ratio, it changes the ratio from 1:1 in 3rd gear (or maybe it's 4th on the C6) used on the dyno runs to something like 0.8:1 thus showing lower power.
Erick Robles Torque to the rear wheels is Torque at the RPM x first gear x rear end ratio. Because horsepower is a function of Torque, they're directly related. Especially when changing the rear end ratio.
wascrash im a bit late lol but 4.10 is gm had many truck's with 4.10 even says in my owners manual 3.55/3.73/4.10 an old Chevy 10 bolt is a 4.11 like 70s when your T case was still divorced
Speedometer works off of the wheel speed sensor, you shouldnt need to change anything related to the wheel speed sensor to change diff gears. His speed should be correct.
@@JBWHITEGT maybe the GT doesnt use wheel speed to know vehicle speed. If you have a wheel speed sensor, all it sees is voltage. It doesnt know what gearing you have, let alone what engine you have under the hood.
This guy has no idea what he's talking about people the readout this he's getting out of his speedometer at different RPMs and mileage is not accurate in the change of gears does not increase any horsepower it lets the car wined up quicker that's it
That is crazy that it is still cruising at such a low rpm. but a .50 6th gear will do that.

Nice. when i get my vette im going with 4.10s all the way FTW!
27.7 MPG isn't bad. I'm considering swapping from 2.73 to 4.10 on my 1999 Corvette C5.
4.10s on the auto is going to be too much, a lot of people swap the 3.42s from the manual c5s. 3.10s were the performance ratios for the auto c5s
@@Drivermod_Josh the c5 came as a manual, are you sure that his isnt manual?
@@sethh8892 2.73s only came with autos
3.42s were on all manual corvettes including the z06
How would not having 4:10s give you 500 horsepower ?

@@damascus-ut1ee no it should not afect hp at all

@@damascus-ut1ee yeah, the hp from the engine doesnt change, its output power on the wheels.
gearing doesnt change horsepower at all. Just like being in 1st gear makes the same horsepower as 2nd 3rd 4th and so on.
410 is a Ford gear. 411 for GM

I have the same car/year. How much was the labor on your 4.10 gears? I'm thinking about getting them, the part online is around $375.
how is the wot pull from 70mph to 120?
My 69 camaro at 2K with 4:10 is going 50mph and buring 10mpg. Lol!
I agree, 4:55's would've actually made a difference, 4:10's generally don't...
@jsb08vette what gear was the car in during this 70mph run
4.10 for gm 4.11 for ford
Nick Wiebe no mopar idiot
where did you get the gears from?
Just thought id ask. Has your speedo been corrected after the gear install.
Speedometer works off of the wheel speed sensor, you shouldnt need to change anything related to the wheel speed sensor to change diff gears. His speed should be correct.
@SethH88 Nah. I did gears on my 08 GT and I installed 410s and my speedo was way off. I needed a hand held tuner to correct it.
@@JBWHITEGT maybe the GT doesnt use wheel speed to know vehicle speed. If you have a wheel speed sensor, all it sees is voltage. It doesnt know what gearing you have, let alone what engine you have under the hood.
@SethH88 Probably so. Never dove into into it to find out for that vehicle. Crazy how I'm commenting on a 12 yr old comment of mine.
@@JBWHITEGT holy shit, I don't even realize how old it was 😂
put som 4:55's in it
Is it auto
you said if you didnt have the 410s you would be putting 500horse down so does the higher gear ratio take away horsepower
This guy has no idea what he's talking about people the readout this he's getting out of his speedometer at different RPMs and mileage is not accurate in the change of gears does not increase any horsepower it lets the car wined up quicker that's it
