Need your opinions everyone help OK I just got heads,cam, and 4400 yank installed. I am still on my stock trans and rearend. I plan on going to the track this weekend. So here is where my question pops in. How should I launch? What is the safest tire to be on? Anything else you guys would like to add is welcome. thanks you <img border="0" alt="[Pontiac]" title="" src="graemlins/formula.gif" />

Re: Need your opinions everyone help I just got a head/cam job on my 99SS couldn't wait to get to the track to see what she would do. Well, I did as I normally do from my prior setup or less power, and resuls were disappointing. I ran on Nitto's in the past and set my Hals front and back as before, and car simply would not hook for any traction. I also use a 3200 Vig convertor and usually laucnh mine at 1800 to 2200 RPM's. If you are already running slicks or something similar, you may not have any problems. Try same technique as before, and if it works--then great. If not, then experiment until you get it right. I know that is what I am going to do, and eventually, I will fine the right combination. I am going with a different tire such as BF Drag Radial and as budget permits--a slick. Then I am considering getting a bigger rear sway bar for better launch control. My best MPH before was 108.9 while with the new setup it went to 115.56 on a A4. The potential is there, once I obtain the traction. I hope this helps and good luck.

Re: Need your opinions everyone help Does the car hop & skip on a nitto? Or does it just hook?
If it hops on a nitto its possible to bust the rear really fast that way. I think thats why I went through so many rears when I had 100% stock suspension.
You won't get axlehop on the slicks, but the initial shock of that convertor could rip the teeth right off the gears.
Honestly Joey, anything could happen. I would leave it on a nitto just to get a good baseline number.

Re: Need your opinions everyone help Make sure you take all the slack out of the driveline before launching.
I do a full quick spin the water... Then pull to the front of the water box... I keep the car in 2nd, and then click into 3rd, and hold it just a little bit. 3rd doesn't have as much tq... I don't want to sit there in 3rd with the engine doing 6000 rpms...

Re: Need your opinions everyone help hey joe, bottom line is this...if you want a "ballpark" on your car...do NOT dead hook it, if you do....BOOM...you will break...id say leave at 2000 rpms and DONT hammer it until you are moving even a little bit....THIS is what I am saying for you using slicks....if you use drag radials, try what you used to try....but be CAREFUL with slicks....youve been warned....
Re: Need your opinions everyone help I am going to disagree with Minty, BradWS6 got like 500 runs out of his stock rearend.
The trick IMO is to do a good burnout like I outlined...
If you don't have both tires equally wet, you can get wheelhop (break an axle) or one tire fire (burn up the posi clutches).
With my technique I cut consistent 60 ft times... within .02 of each other.
People tend to put it in 3rd and what happens is that you just heat up your engine, and don't get as good of a burnout. 2nd has more torque multiplication... Ever watched a 3.23 gear car doing a burnout, shifts too soon to 3rd, and the tires start to bog. Car goes sideways... That is also bad.
Click into 3rd and do a low rpm rollout, otherwise the shock can also hurt the rearend.

Re: Need your opinions everyone help I agree with what Pro Stock says Joe.
Do the burnout like he says and just take it easy on the first run or two...
On your last run of the day, go all out.
PSJ, are you goin' down to US 41 with everyone Sunday? If so, maybe you could set out Joe a few like you 2 discussed just for *****... <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
Or is the car still at Izzo's awaiting Brian's tuning?

Re: Need your opinions everyone help C. I have family plans
I no longer trust folks to spot me in the water box, that's when I started doing the one quick spin one of the tires and pulling forward.
