I don't think it's a good idea inless you have good drivetrain.Any way with street tires it's useless.If you get Mt Et streets a good clutch and rearend then fine.Save up for them you will be very happy with the results.Especially if you have traction isssues.

Well in my opinion if you don't have the $$ to fix the car.. Then you really shouldn't be out there racing it.. Thats just me.. It's cheaper to save the money and do what you want rather than dumping it all cause you have to..

 

We all make choices.

Time and time again I hear stories of how to avoid breaking the rear or smoking the clutch...

The basic facts are slipping the clutch produces heat and heat burns up the clutch. Launching in second gear is going to put an incredible strain on the clutch and the risks, in my limited opinion, are significant.

Launching on the proper tires allows you to vary your rpms according to the capabilities of your vehicle. A lower rpm launch on ET Streets is probably easier on your rear and driveline than a higher rpm clutch dump on drag radials (if they hook).

You want a preload on the driveline for your launch to minimize shock. You want to quickly release the clutch, not dump it. You want tires with a flexible sidewall to absorb the shock of the launch. You don't want your rpms too high or you will bow the rear or the clutch.

Sooner or later we all break parts if we race enough. The best we can do is either spend the money up front or spend it on better parts when they break down the road. Sooner or later everything breaks.

If you can't afford to break parts you probably should be focusing on either earning more income or getting a sponsor, or.... Just take it easy at the track... Have fun, get a Triple A Plus card, and have a beater to drive when something breaks.

 

I've got the money to replace most things, just not to buy a $2000 + rear end and then DR's and rims on top of that.

tnthub, what is the difference between dumping the clutch and quickly releasing it?

 

Less than a second.

A quick release is when your foot releases the clutch quickly at the launch instead of just popping or dumping the clutch. I'm not saying to ride the clutch just release it with a nice clean quick motion. It eases the clutch just a little bit which makes it, in my opinion, the easiest way to minimize the risk of a major failure.

It also makes it fairly easy to judge the tree once you become familiar with the motion.

 

dont u guys run a two step??

 

If you enjoy racing in street legal classes, 2 steps are usually not legal.

 

Don't dump it from 3k. Try 2k, and if your still spining then dumping the clutch is not for you. Slipping it from 3500 may give you better results. I like to play around on the street, see how your car reacts to different things. I had a horrible run in my sig. it was on a 2.2 60ft. Now I dump it at 1500rpms and slowly push the gas until it's floored. It gets a good initial jump forward and doesn't spin much at all. Figure out what your car likes.

 

I will bog if I launch at 2k. It likes to be closer to 3k and feather the throttle. I just need more practice and some suspension things which I hope to get soon. (LCAs and PHD Rod)

 

wow...did not know that 2 steps werent legal. does anyone else on here run a 2 step???

 

This is from the racer handbook at my local track:

No electronics allowed (this includes, but is not limited to TransBrakes, Air Shifters, Two-Steps, and Delay Boxes). No disabled electronic equipment may be left in a vehicle during competition (disconnected air shifters, two-steps, etc.).

 

What is an air shifter? I heard them mention it when I was watching American Hot Rod today, I was just wondering what it was.

 

an air shifter is for an automatic transmission with a manual valvebody. it uses a canister of compressed air to quickly and consistently shift for you.

 

I had a friend of mine who rigged up an electric shifter using the electric door locks on his car...

 

I run a two step and drop the hammer at 5200 right now. To do this you will need the proper setup rear end, clutch, suspension, tire. Its neither easy nor cheap to make a 6 speed 60'. while on a stock motor and stock rear end I ran drag radials at the track. Icould get 1.8s prety consistant with a "fast release" like stated above..launched at 3 grand and kinda walked it out instead of dumping it.

But I must say..droppin the hammer on a full throttle launch off the two step is really really fun.
