Do you know what the car weighs? And track altitude?

Whatever a full weight laser weighs minus the spare. Power windows/locks. cruise, abs, a/c, etc.

I cant seem to find the track altitude, but I know its going to be very close to sea level since i'm only an hour from the beach.

thats really impressive man! I can't wait to get out to the track this year, I have a few little problems to work out first, but then I'll be out there. What rpm do you launch at, I'm having a little trouble finding my sweet spot, I either spin or bog? Also what are your shift points? Anyways good job man!

I was launching at ~4600 rpm, slipping the clutch until it really started to grab then letting al the way out, pedal to the metal. On some runs I'd get some wheelhop at the top of first. I shift at ~6500 in first and 2nd, and was riding 3rd out to the rev limiter Every run I shifted to 4th in, I'd lose time on, guess I still needmore power for that. Its taken me 4 weeks with this exact setup to get launching down, and its still somewhat hit or miss...


I should be window-welding my motor mounts early next week, and hopefully hitting the track again next wednesday. See if a 13.0 is possible on street tires

thats awsome! Thanks for the information. I am considering getting a chip with a stutterbox for launching, but I am concerned about wheelspin if I launch with boost. Either way good luck, and happy boosting.

I'm thinking about the same thing, but I cant even decide for sure what RPM would be ideal for me, especially since I'm planning on doing my rear suspension, which could affect what rpm I want to launch at. Not to mention when drag radials come into play.

 

[hybridshooter]

yeah I hear you. I'm thinking I would see if I could get somewhere between 3500-4000. I might also try some green dot retreads instead of drag radials. I really don't know, gotta get to the track and see how I do as is first.
