Camaro SS LS3 gear ratios.

The Camaro SS LS3 manual has a final drive ratio of 3.45:1

The gear ratios are; 1st-3.01, 2nd-2.07, 3rd-1.43, 4th-1.00, 5th-0.84, 6th-0.57. It seams to have 2 overdrive gears-5th & 6th for fuel economy.

I just found out the Pontiac G8 GXP with the manual has the exact same trans and ratios, except the final drive rear is 3.70:1 which will make it launch off the line better.

The G8 GXP manual will weigh only 163# more then the Camaro SS LS3 manual.

Pontiac estimates the G8 GXP manual to do 0-60 in 4.7 seconds and the 1/4 mile in 13.0@108mph.

What will the Camaro SS LS3 manual do then with the higher rear 3.45:1 gear.

Uh, I beg to differ, the higher rear gear the quicker your acceleration, but the lower your top end speed. If you have a lower rear gear ratio, your top end speed will be faster, but your acceleration will be slower.

That is one of the reasons, back in the '70's you saw very low rear gear ratios in cars to help meet federal mileage mandates.

A 3.70:1 rear will take off the line faster then a 3.45:1 rear. The 3.45:1 rear will have a higher top speed but slower 0-60. FACT

Assuming the same power train. Right.

If you put more horse power behind the 3.45:1 rear end it could out perform the 3.70:1 rear end in all categories. Again, this is assuming you are using the same tranny and gear ratios on all gears?

yes?

All the gear ratios in the Camaro SS LS3 manual 6 speed are identical to the Pontiac G8 GXP 6 speed manual, the diff is the final drive, Camaro is 3.45:1 and the G8 GXP is 3.70:1. But the Camaro has 422hp@5,000 rpm and the GXP has 402hp@6,000 rpm.

um...that's what I said? why disagree with me when you said pretty much the same thing but more indepth?

But how hard would it be to swap out the differential in the SS for the one in the GXP? Sure, you would lose some highway mileage, but would it be worth the boost in acceleration?

I know going from 3.23's to 4.10's are great for your 1320. . .lol.

The 3.45 isn't bad but I would prefer a 3.70 rear more. Like 3.73:1 I had in my WS6 firebird.

I wouldn't switch to the 3.70 because it won't do a ton for you. It probably won't be a value mod either because getting the gears or diff from the dealer or something will cost a lot for not much more performance.


And it might not even make that much of a difference. The Camaro is going to have 275s out back. With the right high performance tires have some decent grip.

We'll see which car is faster when they get here.

^^^^Why are the number estimates for the LS3 manual Camaro so much slower then the G8 GXP manual estimates 0-60 and the 1/4 1320 ???

I'm not sure there would be much of a benefit to go from the 3.45s to 3.70s. My brother and I had pretty much the same set-ups on our cars (Yank SS4000 converter for him and an SS3800 for me, same lids, tunes, and he actually had QTP LTs on his car (I haven't run since I've reinstalled mine) and with his 3.73s to my 3.23s, we've run pretty much the same 60's; in fact, the same. His best run on the OEM manifolds and Y-pipe wasn't really any better. Our cars both made within ten horsepower of each other, so that's about as far a comparison I could make, which is what leads me to the opinion above.

If you want a benefit, you'd have to get drastic and go with a 4-series gear probably, and deal with more noise, lower mileage, and more wear-and-tear.

I don't think the GXP is going to be a lot slower than an SS with the same trannies, so whichever is tested first, I think, will represent the other pretty closely, IMHO.

Guess I kind of misread the tone of your message. Either way, I think we are all pretty much on the same page here.

Have a Great Camaro Day!
