GM listed 420 lb-ft of torque for the SS with 1LE

[tramtwo]

Wow where did this thread go?! GM doesn't give a flip about an individual's insurance cost... I'm sure.

The hp/tq marketing I referred to was in addition to all the other specs listed in GM's official releases. Which by the way has this car being built in Ramos Arizpe, Mexico.

I am sure in a few weeks when these hit the street members here will be all too happy to share their stock dyno numbers as they get their 1LE swag on. I for one am very interested to see what they will look like. Maybe they look just like the SS and it will be uneventful as we all try to describe the "1LE feel" difference.

Now even though the 1LE has 3.91 gears it won't make such a big difference because the trans is also geared differently.

I'll have to respectfully disagree with you if you are saying that dyno numbers will markedly improve just because you switch R&P gears. If that was true, then ALL dyno tests would be run only in 1st gear, because its the lowest numerically and delivers, by a very wide margin, the most 'torque to the ground' to the rear wheels, and thus would give the highest result out of all the gears in the transmission. In real life, many cars give the best dyno numbers in 3rd or 4th gears.

Also, an engine's peak torque doesn't move in the rpm band just because you switch gears -- it just becomes available at a lower vehicle speed. Maybe that's what you meant?

Cheers,

Yeah I saw those too, but think it would look really good with a black border around the carbon fiber. I dont really like the full carbon fiber look and I can do what I said for a great deal cheaper. It always gives me more pride in my vehicle to know I did some modifications by hand, however small they may be. I saw a ZL1 with a similar bowtie as i am referring to. I will see if I can find and post the pic.

See again ... click the Style option. Black bordered option is there!

So it would seem that a lot of future 1LE owners new to this forum don't really understand the thread concept yet or "Camaro." I would hope it is not cause we are just being disrespectful.

THIS thread was started to discuss torque... most every thread in this 1LE sub forum has gone way off topic. Not trying to control anyone. But wading through several topics in one thread discourages those more experienced members from contributing. It also makes having any sort of reference resource for learning useless.

That was a good read.... even a newbie like me can begin to get the jist.

So the useable torque is what GM was going after with the change of transmission and the gears. So not only peak numbers but the dyno curve will also be interesting. Wonder how this will affect tunes and bolt ons?

Fair point. My bad for adding to it. We have gone from HP to sub-discussions on Handling to Badging to Target Market.

The 1LE will definitely *feel* snappier bc of the 3.91's (thus explaining the high demand for the 3.91's), but that's just the multiplier effect of the higher gear ratio, not an increase of torque produced by the motor.

We might say that the 1LE has greater 'fake torque' than a standard SS... LoL
(Come on... its a joke!)

Fake torque = REar wheel torque that you see on a chasis dyno. I think a lot people consider theis real torque since this is the actual power getting to the ground. An engine can make all the power in the world but if you cant get it to the wheels efficiently it is worthless. The manufacturer engine ratings use flywheel ratings from an engine dyno.

For what it's worth - it absolutely feels and performs more quickly than an SS. But it's a matter of smart engineering vs. just adding more power.

Seems to be some confusion about the 3.91 gears. Along with the change in the rear end to 3.91 gears, the 1LE also gets different transmission ratios making overall performance in each gear (1-6) similar. I think the main differences will be seen in 2nd, 3rd and 4th for increased road course performance. Someone with internet skills can probably link to the gear ratios and speed at redline info for each gear from another thread.

Putting 3.91 gears in a standard SS would make much more of a torque multiplying type effect at the wheels that some are talking about.

Originally Posted by Mr. Wyndham

Yup! +1. Can't forget the transmission itself, it was changed, too.

The lower gears are a tad shorter overall, but more importantly, better-matched to a track environment versus the street.

The higher gears, notably 5th and 6th...actually end up taller than an SS overall...engine spins slower, could see a fuel-economy benefit there...

The 1LE optioned LS3 with electric steering and dual mode exhaust should have more power than the standard SS variant.

But owners will have to prove it with dyno and performance testing on their own.

Am willing to offer the car for science... anyone local want to do some before and after dyno testing?

And since the Horsepower number that the dyno gives me is actually mathematically derived from the torque curve, I now have more HP than stock too?

The reality is that this car will not appeal to most Camaro owners and will probably be the least sold of all the configurations except maybe the zl1 vert. Maybe they'll let me print the tee's.

Slogans, we need slogans!!

I'll probably leave the SS logo on the body color grille the dealer sells.

I should have added that it will either be flat black or billet aluminum.

Hm.

Can't mistake what's coming up on you real fast, that way.

I kinda like it...
