Et gains from gear change going from 3.73 to 4.10's. Running consistent 11.50's @119 right now but I'm fighting my 60 ft times. I know I'll probably lose a bit of mph but I'm hoping to pick up .2 tenths or so by getting it out of the hole a bit better.
mike, when you say you are fighting 60, are you spinning?
i have loved my 3.73 on a 325 radial with a low powered setup. what tire are you running and what is the result? IMO its ALL ABOUT the right converter. i dont care what the label says, its what it actually flashes to.

Can't get any lower than 1.63. I've tried all combinations of tire pressure in the rear, front/rear shock adjustment settings, torque arm adjustment, lca position. I'm not spinning, it's just not getting ou tof the hole like it should. A big part of it is my damn TCI stall. It's supposed to be a 4200 but it's only stalling around 32-3500. Suspecting they sent me the wrong convertor.
yea a 4200 stall should result in much more than a 1.6 60' with your suspension.
IMO, a gear change will actually hurt you as the bigger (numeric) gear, the tighter the converter acts. i think you should send the TCI converter back OR spray the bitch

well I agree, thats the price of a tci stall converter. if you pull it out, just get an EDGE convertor. mine was around $550, is a 3800 9.5" built for nitrous and I pull 1.5x 60's running (last year in cold 11.75) 11.91-12.0x. 60's very (for the most part) from 1.56-1.61 with no tire spin. mine is a 383, so perhaps Im building more low end torque, but I only have 3:42 gears also. mostly stock suspension still too.
gator, remember, its not that the conv. will flash lower nec., its the the gears are doin more of the work. so the car will drive better, and provide less conv. slippage/heat with the numerically higher gears. when I switched from 3:73 to 3:42's, I hated the change in rpms driving around town. rpms are HIGHER now on light acceleration from stop lights cause the eng is having to work harder to accelerate at X rate.

you have a brake? Can't get any lower than 1.63. I've tried all combinations of tire pressure in the rear, front/rear shock adjustment settings, torque arm adjustment, lca position.

There are going to be alot of factors, weight, power, stall, gear, tire combo. You represent what I tell alot of people, get the motor combo set then tweak everything else. You may put 4 converters in the car, shave a few pounds, and change the gear once or twice with different sets of tires before you find out what that particular car likes.
Thats why its called "Test & Tune". The part that could truely make you go broke.

went 11.37@120.45 tonight. The track was a little slippery and the timing lights werent working so I got NO 60ft times. Hopefully they will get them ironed by tomorrow for the VAMP race.
how did the 60's feel? that sucks that no 60' times man. but, better to see the gain in ET and not know the 60's though. imagin, you pick up say .10 in sixty, but cant see the ET. that would **** me off worse then seeing the ET and not the 60'.
how does it drive on the street compared to before? like it better with 4.10's or the old 3:73's around town?
congrats man.

didnt pay much attention to this, but the other fella is right, it wont stall to its full potential w/o a trans brake. and, there will always be slight diff. from where they try to set it at, depending on all the car variables such as weight, gearing, power curve, ........
but, running 11.3x with 4.10's compared to 11.5x with 3:73's and 1.63 sixties, you should see the gain in 60 as well as the ET. so Id guess you'll be running low 1.5x 60's now.
get back to the track and post up when you can give us some 60's too.

pirate knows the differece b/w flash stall and footbrake stall. i believe he means it is only flash stalling to 3200 rpms
btw mike congrats. i bet you are ni the 1.5 60' esp considering that new ET. also congrats on 120 mph n/a!
