For those of you with aftermarket torque converters, what do you typically set your window switch to activate the spray at? I tried setting mine to 3100 with a 3200 stall and it resulted in a smokefest with 275/50/15 drag radials. Suggestions?

 

To many variables to give a blanket answer. It all depends on your suspension, size shot, your other mods, and the surface you're launching on. Try 3500 then go up or down, depending on your results.

 

i have a 3600 stall in my camaro and typically choose a 38-4000 rpm pill to turn on and a 6200 to turn off with a 6500 shift point

 

sprayed mine yesterday for the first time with a 150 shot. i have a 3200 stall and set the window at 3400-5600 on/off. car does not spin one bit from 10 mph up. running MT drag radials.
200 above the stall seems to be working fine for me

 

I dont mean to hijack the thread but are any of you running a stock 10 bolt rear while setting the rpm window a few hundred rpm above the flash stall speed? (on sticky tires)

 

I'm running the BMN Window switch with the first gear lockout and setting it to spray at about 3500 (3000 STall converter). The first gear lockout seems to be the best solution to still limping on the factory 10-bolt.

 

I sprayed a 75 wet off the line with a 3600 Yank. Stock 10 bolt 3.73 gears, no girdle. I cut a few 1.56 60-fts. No problem. Got some nice wheel pulling action too.

 

I have never used a window switch on my auto.(the stall will keep it about 3k) I sprayed it with a 175 out of the whole, and let the trans do its job. (shift at the shift points) all on a 10 bolt.

 

I never used a window switch either on mine. Dope out the hole with a 3,600 stall. Need to see how this new 4,200 likes the dope.
