m6 guys, what do you shift at?
m6 guys, what do you shift at? I have a basically stock car, I'm just wondering where I should be shifting at, normally I shift around 5800 on the tach, so given how the tach is off a little I guess that puts me at 5400-5500? I dont know.

Since you are basically stock, you are probably doing fine shifting where you are. If you want to get more precise, you would need to take the car to a dyno and see exactly where your peak hp is being made. Then I would get a shift light and set it at the determined shift point. I never liked having to try to watch the tach and the road at the same time when my foot was on the floor.
Stock head and cam shift out of first at 5800 RPM, then the rest of the gears at 5700-5800 RPM especially in top gears. The stock LT1 has no 3rd gear and up pulling power past this.
Some people are hell bent on shifting stock H&C LT1's at 6000 RPM. All things being equal you would smoke the other guy shifting to high.

Dont get a shift light for a stock ride (just looks like rice).... It should be pretty obvoius to feel where the powerband stops just from driving the car all the time. I mean, if you just goto the track once and make 10-15 passes, you should be able to tune your senses to hear and feel it assuming your used to driving a manual all the time.

With all the bolt-ons and tricks you can feel the LT1 wants to shift at a much higher rpm. I shift my fully modded stock heads and stock cam car at 6100, it likes it !

Really... I guess I have been shifting too low :S
My car has CAI, Chip and Magnaflow cat-back (installed before purchase of car) and I shift at 5500 or so... So I should be shifting 300-400rpm higher? At what rpm does flat float occur?

stock cam quits making power at 5800. however you need to shift at around 6000 or maybe even 6100, bc that will put you higher in the power band once you get into the next gear, thats what ive always heard anyway.
even tho at 6000 the cam has quit making its power, when you shift up a gear at 6000rpm, that will put you 200-300 rpms higher in the next gear and those extra rpms supposedly make up for the over reving in the previous gear. just my .02. oh yea the stock rev limiter is at 6200 if that means anything to you.

Stock limiter is set at 5650 or 5750, can't remember 
I moved mine out to the way through PCM tuning and use my MSD box to soft touch the rpm at 6300. I agree with shifting the motor at 200 to 300 above what you think so it will back into the phat of the cam on the gear change. I'm usually around 61/6200 1st gear to 2nd and all other gears after 60/6100 depending on how it feels. I have squeezed a 12.61 @ 109 shifting this way.

My main question is what RPM to I drop the clutch at for best launches... This is my first manual car and I know I'm babying it... Rev to (Insert RPM here), drop clutch and step on gas... correct? LOL.
baby it

I wonder which one is lying, the in dash tach or the autometer? I'm shifting it at 5600 according to the autometer tach, stock tach always reads 100-200 lower though.
After today I have decided the CF dual friction clutch isn't too happy with 2-3 and 3-4 powershifts, didn't seem to get any quicker. Actually got slower.
I'm curious as to what people launch at on street tires, I can't seem to launch worth a damn.
