I plan to spray 125-150 shot on the street and I have an M6. Is 4:10's gonna be too much gear because I dont want to be shifting into 5th before the 1320. Do you think 3:73's will be a good median?

Tranzor

Depends... if you have a cam that pushes your shift point up to around 6500 rpms, then no it isn't a bad idea.

If you're still on stock shift points & rev limiter, I'd stick with 3.73s if you're spraying.

but how high can u spray with stock bottom end in the rpm range?

Tranzor

I'd probably set my window for between 3000-6000 or maybe 6200 at the most no matter what cam I was using with the stock bottom end.

My 4.11 are great on the street on my stock motor, BFG drag radials and T56, but I have serious traction problems with the 150 wet shot. I wish I had 3.89 r/p.

Can anyone link me to the speed-gear ratio chart? I too will go juice (100-125 wet shot) next winter, maybe with 4.10s.

My H/C combo allows me to 6800 rev limit. Enough gear for 1320 with stock tire size?

Race Car Driver

wow, 6800 rpm on hydraulic lifters! Now that's what I call pushin it. I think you'll hit 5th gear in the lights.

That is not all that rare to be reving a H/C car to 6800 rpms.

Most do that!

1ScrudeDude

I will agree that I am a part of a vast majority. And I have not seen many problems with the lifters, even with some racers going up to 7200 RPM with the hydraulic lifters.

I even misshifted and spun the engine WELL ABOVE 6800 and so far no problems with the valvetrain. In fact, after that misshift, I went on to get a personal best that same night.

We spin our stock bottom ended H/C car to 7200 rpms on every pass, but we have 4.33s and 28" tires. We still use hydraulic lifters.

Race Car Driver

I'm shifting my little all stock motor at 6000 when on the spray, because I want it to last. Hell, I'm shifting my solid roller n/a 622 at only 7700 rpm! Remember, it's only got a limited number of revs in it.

Thanks.

But the chart doesn't work unless there is a "pre-set" in the drop down list. And they only have a 3.42 rear for the LS1 M6...

Either that or I'm a retard.

I have a 95z six speed with 4:10 and a hoosier 27" tire, i sprayed a 150 shot the whole way and didn't hit 5th gear, shifting at 6200

1ScrudeDude - You can select the pre-set M6 from the drop-down list, but then alter any of the values in the text fields (such as changing the 3.42 to 4.10) before clicking the calculate button.

So the taller the tire...the more mph you can get out of each gear??

Not to up on all this stuff....but need to know.

1ScrudeDude

Uber cool. I tried it at work and it didn't compute, but here at home it calculated Stupid filters on work computers!

I'm good to 127 mph and I hope to challenge that I'm hitting 117-118 traps now NA. Therefore, I am going to leave the 4.10s in and go with a slick and/or taller tire. The 4.10 ratio is just too good a gear for this set up, plus, I want to maintain some digs when I run on motor.
