Speed shifting. I am using the clutch. It's a TKO-600.

nice man and good shifts, are you power shifting or speed shifting?

My first gear in the TKO-600 is a 2.87. If you have a 4V making under 400rwhp then 4:30's are great! My Mach 1 is making 465rwhp now with the Procharger so the gears are now to much. I'd go with a longer gear like a 3:90 when you're 400 power. hmm...as for weight savings. You can remove the A/C. Remove the ABS pump and system. Drag brakes. Front sway bar. Sound deadener. My car only had 297rwhp when I made these 12.1 runs! And as for weight savings...not to much. Never got to weight it but I'd figure the 8 point chromoly cage evened out what I had taken out! lol!

Just curious what gear ratios are you running in your TKO600. I have a T56 that has a 2.97 first gear and I was going to go with 4.10's or maybe 4.30's. I need some advise also on weight savings besides the normal stuff, no spare tire, carpeting in the back, rear seat delete, lightweight wheels. Was thinking on going to a manual rack and pinion steering and rear trunk mounted 11.5 lb battery. Very nice run, I am hoping my car will at least be in the mid to high 12's.

good run! hopefully with a little suspension work and a gear my mach will be there soon. I just need the tranny to hold it now.

Thanks 03machwon....and yeah it has a TKO 600.

LT_WON, when you powershift you still use the clutch, powershifting is just holding the throttle down all the way between shifts, and yes he is powershifting

thats some pretty impressive shifting bonestock. I think i gave you some shit on you tube about your shifting and you said to look at your other vids. Well you were right thats pretty damn good. Is that the stock 3650 tranny in there. My mach doesnt allow shifts at very high rpms like that. Anyway keep posting vids there pretty good.

Nice mach man i have 04 mach 1 with 4:10 gears. I wanted to know does the 4:30 gears hurt your gas mileage in the city and hwy and if not i wished i would have done the 4:30 gears. Dam u can drive keep more videos coming.

Thanks!
