My stock driveshaft went bang. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Launch as high as you want if you can afford a new one. The rest of your drivetrain is stout, might as well finish it off with a nice Denny's nitro driveshaft. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

btw what is your cat back set up?
3" pipe over the axle into a Y w/ 3" bullets before each tip??
how does that sound? <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Thats my exact setup + Exaust dump. The bullits are the tips <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> 3" pipes in the rear Y also. Well its MEAN sounding. I get compliments EVERYWHERE i go. But it gets anoying once and a while since its a daily driver. LOUD inside and out as you probly guessed. Sometimes i want to get rid of it. But when i think about it i'm like WTF i like the attention. So its a toss up. Not bad over 70. But 55mph when your lugging around it DEEP+LOUD.

So you think that sticky tires will help? Sounds like I raised the bar. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

So do the base police like the exhaust?

When will you take it to Centerville? Let's go at it.

I launched at 6k with 28x10 ET Drags. Helped me cut a 1.755 60ft, but i need a better clutch. But i was able to pull the front left wheel up on more than 1 occasion. <img border="0" alt="[Firebird]" title="" src="graemlins/formula.gif" /> Good Luck

You need to get the ET's hot and stickey. Drive around the water box and back into it to get them wet. Pull forward about a couple of feet,hold the brakes and do a good 4 to 5 second burn out, get them smoking. Let off the brake and let it go forward you'll be able to tell they are hot enough when they chirp as you slow to start your stage. I have a Vig 3200 converter and it likes to launch from idle. Try launching from idle then increase the launch RPM by 250 RPM increments until you get the best 60ft.I strongly do not reccomend 6000RPM launches, not good for the tranny or the rear end.

I used to launch at about 5500 rpm on the ET Streets but I also had the stock clutchn which took some of the shock out and my stock driveshaft and stock rear with 4.10s survived. I ran mine between 12-15 psi. I had tubes in mine due to picking up crap on the road and getting holes in my first set. Just experiment with different tire pressures, launch rpms, etc. Have fun.

the 6k launches have been doing fine for me iv done 20-30 passes with no problems, but try the different tire pressures, the trick is have as much PSI as possible and still hook.

A couple of thoughts....all concerns the track vice the street...

Run as much air pressure as you can get away with and still get traction. It has been my experience the M/T slicks/ET Streets like less pressure than other slicks. With an M6 car, you'll be shocking the tires pretty hard, so you'll need a lower pressure than an A4 car would require. I'd suggest starting around 12 psi and working up/down from there. It will take some experimentation.

Your T56 has a rather horrid 2.66 1st gear. The 4.10's help, but even then, your don't have a lot of torque multiplication in 1st gear (the most important gear in a drag race). As such, and parts breakage aside, launch as high as you dare, or as high as the tires will hold. It will take some experimenting to find this point. If you're getting good traction, and the clutch holds, you'll bog - as such, the higher launch will result in a higher rpm as the car comes off the bog, thus moving the car better. If the clutch slips, all that goes out the window.

If you're worried about breaking something....well....I suggest Drag Radials. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

I see no reason why your stock (steel?) driveshaft shouldn't be fine. I guess its possible to break em (as Onyx pointed out), but it would seem to me that this is a rare event. The clutch on the other hand....

I don't like - nor do I use - tubes. Unnecessary extra weight, IMHO.

As for the burnout....agree with Mark...you need a 4-5 second burnout. It is very important that you do it in 2nd gear vice 1st. The reason is tire speed - a 2nd gear burnout will get the tires hotter, quicker. 3rd is even better, but I doubt that is possible with a mostly stock motor and 4.10's.

Good luck to you.

Thanks for all the info guys. And i'm running 4.30 if that changes anything. I'm not worried about the RAM clutch. Mainly Tranny/driveshaft (aluminum) Ill be going to the track if it dont rain (anduandI) BUT it will probly be Prescott FRI. Unless it gets rained out then ill his C-ville. About the bar being raised. (YES UR FAST) But i'm tring to catch the 9.3(1000') pass out of one of our club members. Heads are soon to come.
Well it seems not everyone is worried about the driveshaft like i figured. Si my guess is Start with 20psi go down from there. And Start with 4500 rmp launces and go up from there. Thanks, So is a 1.7 60' about what to expect...
And ill give the 2nd gear burnout a try. I dont thin ill have a problem. Whne i'm wanting to give a show i burn them in 2nd from a start. Burnouts last longer that way.

Elite hot rod got it pretty good. I usually luanched at 5500rpm for best results on the ET streets and ran 11psi.

The Guy in MY 99TA

I am not sure if any1 mentioned it(didnt read all replies) but if your going to drive much on the street with em ya might want to be a little careful b/c they won't handle as good as what you are probably used to

Thanks yea i read about that. I just had them on for fitment and test purposes. I drove them around aired up to 28psi. Felt drivable. A little swervy but not bad at al. Wouldnt want to try it any lower though. But Thanks! I dont plan on driving on them unless i happen to get called out. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Tim,

Likely going to install Hooker's this weekend. Centerville is iffy because of that. Was there last weekend (15 runs toward the lower end of 10.4 to 10.1). Let me know on Saturday if you are going, maybe I'll make it.

I have those same tires and I use 16 - 18 lbs at the track. I have an A4, but nail it with a YTP 4200 & 3.73s. So far, good for 1.61 in my boat. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
