No pal, I am using the correct ratios, ones in the manufacturer's specs, ones I have verified at the track.They are correct.

I don't know what your problem is or where you get the info, but you are just full of it and kidding yourself: a 3.42 F-body will not run 196 at anything realistic for an LS engine RPM.

If you want to believe your own fantasies and BS, fine, but take them somewhere else.

So if you have the fastest Camaro ever built, then why are you on a CORVETTE site and not out killing yourself doing 196 at 6500 on a highway. Dude, seriously, stop giving F-body owners bad names.

[sm=smiley36.gif] You are seriously cracking me up! Yes, 3.42's are the correct gear ratio, but without the ratio's of each gear in the transmission, you will never have an exact MPH. If you would have taken 1 minute of your time to stop bashing the Camaro guy here, and check the site I posted, you would see what I am talking about.

If you have checked the GM transmission gear ratio for a 95 M6 for 5th gear, you would have seen that it sits at .74 Use that in with the stock tire size, the 3.42 gears, at 6200 RPM and you will find that it is the speed I claim it is. Are you getting a different ratio for 5th gear? This is the one the site posts, and is in the GM manual.

Let's see..............yup, just as I thought...........Lee's got it!

So Lee, how was your weekend? I saw my G-daughter for the first time!
Too darn cute!!!;)

I think that gear calculator is a bit off.

I went to the f-body website and tried the gear calculator for my car (94 on LT1 F-body, modded engine but stock M6 drivetrain) and got a 172 mph top speed at the stock redline of 5700, and a 186 mph top speed at 6200, not over 190 like claimed. That is too high: I know my car tops out at its Lingenfelter redline (6000)at just over 165, because at an even 3000 RPM in 5th it runs exactly 83 mph. both speedo and tach have been calibrated at the shop and are within 1%.

I checked a number of the other cars that you can pick in the gear calculator selector, and I think there are many small errors. I noticed 3.42 gear ratios are sometimes listed as 3.45, and I know that 4th gear in many of the M6s (including mine) is not exactly 1.00 to 1 as it seems to be in every car there. In many M6s its a bit higher - 1.08, 1.15 in some, etc.

Regardless, the results are not correct for my car or the LT1 vette, I know that, overestimated speeds in gears a bit.

Just my two cents . . .

By the way Lee Willis, I read you comments about Camaro owners on another thread here. Hope you don't count all Camaro owners in that "fanatic" category. some of us are good guys!!!

I only checked the 4th Gen F-body M6 gear ratio's on the site, but all of them are reading 3.42 for the rear. This is one of the main gear calculators used on another forum with almost 70,000 members. I didn't create it, therefore I don't know all the details behind it. I would guess that since many other calculators don't have anything other than a tire size and a rear end ratio, that this one would be more accurate than others.

i brought my car today and we hit 150 on the PA Turnpike on the way back to jersey.

Good way to get a ticket. PA Turnpike is pretty heavily patroled on weekends.

What car did you get?

You guys have alot more courage then me....Please do be careful out there...Id hate to see a forum member die because of something that could be avoided.[8D]
