I dont know enough about differentials and the physics behind it all, but I can say that no matter what I seem to do I always seem to spin my right tire where the gas tank is. Will this change with DRs so that the one thats already heated up will stick after the first burnout?

 

I don't know. I usually just do one big ole' burnout like this (My car, me driving)

Long burnout Scott

(398)

 

I could be wrong but it looked like smoke was coming from both of your rear tires so it looks like you have a limited slip differential. If so I dont think Veetec's 2 burnout rule would be directed at you. It is directed to us poor folks who only have one tire spinning at a time due to an open differential.

 

Yup. VLSD, actually. It roasts diffs though, so it ends up being a peg leg like you guys after a few runs...

 

Yes, because when you heat up a MT DR, it will bite.

 

Sorry for picking on you, but comments like this are so common. I think that alot of import guys don't understand anything about American "muscle" cars or solid axle suspensions.

The other good one is watching an import guy try to figure where the cam is on a pushrod V8, and then see the look of puzzlement when you explain where it is and that ther isonly 1 cam in the engine, too.

 

So it would be two burn outs infront of the water box?

What psi do you recomend? DR

 

+1 good question, I completely forgot about tire pressure.

 

I usually start out with 15psi on M/T DR's and then see how the track is.

 

cool, thanx for the info.

 

Good info on wheels and tires for drag racing in this section lately. Keep the good info and opinons comming guys. My plan was simply 18"drag radials but I am starting to reconsider after reading a few of the recent threads.

 

Slicks and there ability to wrinkle the sidewall and absorb some shock are slightly easier on the car IMO than DR's that have stiffer sidewalls.

With that being said either set with an inexperienced driver can = axle snap off the line! In your situation because you are NA and likely will be for a while I would go with the DR"s. That way if you want to mess around you can mount them and go out, or drive to the track on them. Ive driven to the track a few time on ET streets and combined with steel belted tires up front its NOT a fun ride. Good luck.

 

I just like to comment that Dr's or slicks will NOT improve your driving. It took me a awhile to actually learn how to launch with them and cut the sub 1.9 60's
Dont expect to just go with slicks or DR's and expectin 1.7 60's

 

+1 It takes a while to believe that you can launch above 5000rpm's

 

This may be my inexperience talking but I haven't heard of NA guys snapping axles how does this happen and what can be done to prevent this from happening?

 

Nah, you know me I am a realist. I know this will take some time to get used to, I just want to invest in a set of dedicated drag wheels and tires. Plus since Im planning to become more serious about it I dont want to continue burning up my street tires racing.

 

Very true

I have snapped two axles in my quest for 12's

This is going to be the year


I also have a base, but switched over to a vlsd. Never ran on DR's though. Either one you decide to go with will be a improvement of street tires ONCE you understand how to launch with them. Cant stress preloading the drivetrain enough. Plus, dont let the guy next to you determine when you launch. Take as much time as you need. Clock does not start until you move in a test in tune setting.

Preloading is basically letting off the clutch with the RPMs revved just before the point where the car is moving correct? This helps with the drivetrain shock I imagine?

as far as the 12s you will get it, its just a matter of time. goodluck with it as I hope to do the same myself.

 

Correct, you dont want any slack in the drivetrain. Everything has tension on it.

Good luck

sounds good, I experimented with that at the end of the season so I will make it a regular practice with the DRs or slicks whichever I go with.
