Getting psyched up for DR's..

**CRS MSL** · 06-02-2009, 08:19 PM

I ordered a set of 275/40 x 17 DR's and wheels from Moe, anxiously awaiting the shipment. I'm shivering with anticipation of the new 60's I should see, best so far is 1.99...

but I got some questions running thru my mind...

1. Do I need to add a lot of heat to them in the BO box, big smokey or little chirp?
2. What kind of pressure should I start out at, what's the lowest I should go?
3. Where is the half shaft risk, in the burnout or the launch, vids I've seen always seem to show it failing at the launch?
4. Any maintennace routine for keeping them functional while they are in the garage?

Thanks fellers...

I am interested as well, but cannot answer your questions (Sorry). But I wanted to know, how wide are the wheels?

Wheels are 8.5" wide.

Well congradulations for taking the next step in the I want to be hooking world

Unfortuantly there is a WIDE variance in the answers to your questions.

#1. Depends on the DR you get. NITTOS require the longest to heat. Hoosiers are sticky as all get out once you found the right spin to heat them up. Most though after the intial burnout .... the subsquent burnouts do not need as defined. ( I know I have gone through several sets of DR's)

#2 Depends on DR you have, track conditions and the temperature. Anywhere from low as 13lbs to 23 lbs.

#3 The PROBABLITY is high...that you may break your stock halfshafts. Though there have been a couple of "Dragsters" who have managed to stay with the stocks with no issues. They are the "unique" and that ability is a well kept secret

#4 I have never had a single set last the entire season so I could not tell you...

Though come to think about it ... I do have a set of M/T ET Street 275/45/17 used only twice which have been laying around for a year now.

Yah, hooking is good, particularly for consistency. I'm already on the edge of the Sportsman class but with DR's I should be able to run at the top of the class consistently without going balls out each run, little bit of lift at the big end... They are Hoosiers, sounds like I'll be doing some experimentation.

So 13 is a low as a guy should run them?

I expect that they'll eventually break, just hoping to find the danger zones so I can stay out of them.

How many runs do you figure you get out of a set? Do you rotate them L to R (since it seems that the peg leg is 'generally' left side?)?

Thanks for the thorough answer, much appreciated!

1. You won't need to heat them much. When run motor only, I do a short burnout. Just enough to see a little smoke. I heat them up a little more for the nitrous passes. I've never been able to spin them on motor.

2. I run 20lbs. The lowest I've gone is 18.

3. Do your burnout in first gear. Let off the brake and the gas at the same time. Don't let the tires grab while still in the throttle. When launching, smoothly but quickly floor it. Don't mash the throttle. You should be fine, but you really need to upgrade the axles.

4. I just store mine in the garage. I put a blanket over them. You don't want them in direct sunlight. It could dry rot the tire.

Hope this helps.

If you're not spinning on motor are you bogging it, upgraded TC?

It sounds like it's not simply torque from the launch that breaks but more the impact of no-traction/traction that does it? I think I can stick with that plan that pretty well, thanks!

Axles are on the list, saving my coin for them anyway.

Right on, that I can do as well!

Mickey Tompson recommends dropping the tires down to 5lbs when not on the car. Also keep them away from heaters/ACs/etc and avoid sunlight.

As far as a the 'peg-leg' burnouts, less air pressue = more traction (to a point), so I experimented with it a bit, and got both rears to light up equally by running 2-3 more psi on the drivers side.

I had better results in the 22-25 psi range on my M&H's, but I've run my best passes on my Nitto Redlines.

Very interesting..... at such low pressures did the imballance produce any negative effects, drifting/pulling?

Well that's kinda interesting! .... Never thought about that!

If I'm only getting one tire to spin, I just pump the brake and let the car move forward a little. This always gets the second tire spinning. I've never had any issues with a peg leg burnout doing this. I can always get both tires spinning.

Eric,
Just come back up to woodburn or PIR, bring the radials, and I will show you how it's done....lol.....the hoosiers are easy to heat up and they hook up great.
