3200 stall best launch method?
On previous cars/trucks I have not seen much difference in short times by either launching off idle or brake stalling before launch. However, at the track folks argue one way or another all the time. I will say with my stock converter I did not see a change either way. I just installed my 3200 billet single disk and am curious how you stalled Vette guys are getting the best 60's? Once the weather in TX dropps below boiling point I will get back to the track to test!

A lot of it will also depend on track prep and just how high you can bring it before the tires start to spin and/or the car starts to push through the beams.
It's going to take some trial & error/experimentation as each car can react differently.

with the above post - mine has a 3000 stall, I get best times flashing it to about 1250 before launch, one of my kids kicks my a$$ with it by brakimg it to about 2800, then letting it go, and my other kid beats me by braking it to about 2000, so you have to experiment with your car on various track conditions to see what works best for you and your car..... my bud called the guys at Precision industries to ask them the best rpm to launch with his Vig 2800, and they told him to flash it to around 1250 or so and let the TC do the rest, and that seems to always work best for him regardless of track conditions....

However, I have found lately that by being "up" on the converter, that your (my) reaction time may/has gotten better. If you're just chasing an et, the above thought comes to mind. In a racing scenario, I would recommend being 'up' on it, try around 2k and go up or down from there.

Went to the 1/8th mile track tonight. I tried two diffrent methods, the first was launching at 2200. This resulted in two 1.6 60's and 7.1@98/99.
The second method was launching at 1500, this method resulted in breaking the tires loose and smoking them..
So I have a little more testing to do to get the right combo, but overall I am pleased.
*These runs were all on 305/35 -18 MT II street radials at 26psi.
If anyone is interested the DA was 2115
Best Run - Launch at 2200
60' 1.6197
330' 4.6139
1/8 7.1038
1/8 98.34
