Launch technique for my car...

[SadbutTrue]

Might be going to the track in a few days. I have the posi/gears in, have added a tranny cooler and new suspension, and pretty much an entire ignition (box, ignitor, wires, coil) since the last time I ran (which I won't tell you how I did because my tranny overheated and decided to stop shifting and a few other reasons).

Anyway, I'm trying to keep up with my brothers 85 Vette (stock except for some turbo mufflers and a throttle body bypass) that ran a 14.7 before those mods (both cars are auto). To get his best times we found we had to stall the converter to about 2000 (i guess thats what the Vette came stock with). I plan on shifting my car manually, though I don't have a tach so I just kinda go by noise. How high should I stall my engine? Should I try to get any wheelspin? Anything else I should know?

Keep in mind my car has these really, really crappy 195 tires in back, so that certainly doesn't help me.

Wow, it's going to be hard to hook up out of the hole with 195s on the back. Even after getting the tires sticky in the waterbox, you'll probably still have to feather it a little off the line or else you will have some wheel spin. 195 is tiny! lol

Even my little 235s on the back of mine won't hook up and I've got a tired old 302.

the tires weren't my choice, my dad got them because he liked the stock look way back when the thing got restored. I'm trying to burn them off but they are definitely built to last, and don't seem to wanna go anywhere...

you'll gain at least 2 tenths if you take off those fuzzy dice!

best way to get traction is to make sure tire pressure is at recommended level and don't do a big burn out, stay out of the water if possible, just pull around it and turn the tires over just enough to clean them off, do not smoke them as street tires will actually get slick if you heat them up, also if you lower the tire pressure the middle of the tire will bow upward giving you less of a contact patch, with my 225's I can get a 2.00 60' and pretty good traction when leving just so I am close to the front of the line, once a bunch of cars go it's hard to hook at all due to the track not being prepped anymore and those d$#@ front wheeel drive cars, I usuallt stall to 2000 rpm when I leave, Good Luck


that was when I had 3.55 gears
