When I had a manual, the launches depend on finding the sweet spot where the car wouldn't bog and where it would launch with a slight spin. This was when I was racing my daily driver trans am so i wasn't too keen on blowing the rear end. I'll let more established stick racers chime in the real tips and tricks!

Rob, that is my gut feeling as well. Below is a post that seems to align with our thinking. I was getting a lot of bog at the line. I had predicted that I'd be blowing the tires off, and I was dreadfully wrong.

Just curious, what kind of car do you have that only weighs 2550lb empty?

 

I had a feeling that this would come up. You guys always help me out, and I do my best to help out others. So, I'll give it up. I have a '69 Camaro drivetrain (exception: independent ford rear) hidden inside of this:

 

seriously?? that looks like a miata... noooooooo really?

 

Yep, that is exactly what it is. And, it is very fun.

sweeeeeet, slip the clutch more, dont just pop it and throw some slicks on it

Thanks, I'll give that a try. I have a bet with one of my friends, so I'll try to get consistent with street tires. He says that I'll gain a full second with cheater slicks, and we have a steak dinner on the bet.

Shouldnt that weight and rwhp be running over 105 mph?

In theory yes, that is why I'm looking for help so that I don't drive like heck at the strip again.

at what RPM's you pass the line ?, those 327 like rpm .

 

I was around 6000 rpm. I don't plan on getting out of 3rd in the 1/4 mile. Even if I throw the belt I can make it up the hill and around the corner without spewing any coolant.

 

Just allined the pulleys and buy a Dayco Top Cog belt , :yes:great belts

 

That sounds like a great reason for me to go ahead and get a new set of pulleys to match that supercharger that I want.

 

As it's already been said, you don't want to dump the clutch all at once. That's good for doing butnouts, but not for launching a street car. You want to let the clutch pedal out faster than you would when driving normally in traffic at a green light, but still gradual, and all the while giving it a lot of throttle. How much throttle you give it will depend on your combo, and is something you're going to have to experiment with.

But after your experimentation with this method, you should try to adopt a pattern that's close to being the same on every run. You probably already know this, but drag race launching with a manual trans can be real tough on some clutches. Even on some aftermarket ones.

 

Just a question......Your not running air shocks are you? Going to drag shocks or even regular in the back are worth some 10ths.

 

No airshocks.....The setup on the car is coilover, so I don't see me changing much in that area.
