Question 1LE rpm's

hi 1LE owners..i would like to know,
how much the ls3 is running--rpm- in 6th gear at 60mph and 75mph. since you have 3.91 gears.

Thanks!

Generally 1200ish for 60mph and about 1800ish for 75mph. I think... I know for a fact that 80mph is @ 2000rpm.

Due to the gearing in the 1LE transmission, the rpm's are actually a tick lower cruising in 6th gear than a regular SS.

SS has the M10 transmission with 3.45 gears, and the SS/1LE has the MM6 transmission with 3.91 gears. Take a look at these threads for some background info

I thought it was the opposite... isnt 4,5,6 the same but with 3.91...higher rpm?

Wouldnt a stock ss vs 1le over 1/2 mile the 1le would have the advantage...I know the 1le loses a little mph topped out but, you would get up quicker in 4,5,6, right?

The whole purpose of the tranny rear end set-up in the 1LE is to have closer rations (not as big a difference between the gear ratios) for gears 2 - 4. 1, 5, and 6 have very similar final drive ratios between the two cars. Closer 2 - 4 equals better lap times on the road course. If a larger rear gear is mounted behind the same transmission, it will lower the cars top end, and reduce the time it takes to get it there (Assuming the car can hook-up at the start). All that changes when the gears in the transmission change as well. Putting a 3.91 in a standard SS with no transmission change will make it quicker than it was (Again assuming it will hook up), but it will not improve its ability to be in the right gear on the road course. I hope that helped.

Smile 1LE gears and Dyno.

I installed the 1LE gears in my 2010 Camaro, DSS One piece driveshaft. JRE belt tensioner, ZR1 plugs, and GMS-28-1811HT plug wires. My Camaro was on the dyno before I added those parts on the car. It was Dynoed at 558 hp. I also installed a Roto-fab CAI. I just had the car on the Mustang Dyno and It did 603 hp. If I ran my car on a Dynojet the rwhp would be 12% higher at 675.46 HP. Those that disagree with me can reply or post !!!

I am not yet disagreeing, just making sure I understand. You are saying that you added 3,91 rear gears, a 1 piece drive shaft, a different belt tensioner, different spark plugs and wires and a CAI and gained 45 HP with the same weather conditions (temp, humidity, barometric pressure)?

There's not enough information here to agree or disagree. More importantly, this post has nothing to do with the subject of the thread
