It will take finesse to launch a stick car on DRs without spinning at your power level. Lots of clutch slipping and smooth application of throttle.

Im running an auto with a factory converter. So footbraking up to about 1500-1800rpm should be close to the sweet spot? Then again I know it will take some trial and error to try to find the sweet spot but im running an auto. My sumi's just felt like plastic or wet or something and that was leaving almost from idle and rolling into the throttle. It would start spinning in second also with those tires. They are fine for travel and riding around on the streets imo but they leave ya kinda embarrassed at the track with all the slipping/sliding.

Those are just the worst tires ever cause a stock stalled auto has zero ***** out of the hole....

Amen. Trying to "launch" my car feels like the sweet spot is so small i'm throwing darts at the universe.

lol, every auto needs a 3500+ rpm stall converter in these cars, only way to get the things to go anywhere out of the hole.

Ehhhh I plan on rebuilding this car next winter/spring and I dont plan on any higher than a 3000 stall. I want this thing to have street manners and I don't want to skip out on any of my early power. 3500 seems extreme for a PD street car. However I am not the most knowledgeable on TCs, especially in regards to drag racing.

With a PD blower you would be fine with a 2800-3200.

With a centri blower you need the RPMS up to make boost, thus why a 3800 is fine for a vortech car.
