Factory T LOK really brings out the one wheel peel wonder, doesn't it. - VIDEO

[Ronin]

So my first trek to the track with the DRs. Not a happy camper when my best time was with no water burnout and was still a 1/10th behind my best with street tires. I was getting nothing but one tire fires all night. Best 60 was 1.99, but on that run I missed 3rd. I'm thinking about going again if I can get one of you guys that's local to phoenix to come tell me if there's anything I could be doing better. And what particularly sucks is I recently had the diff rebuilt.

I posted this at the bottom, but here's a video:

I think I'd go back to the shop that recently rebuild it and have see if they can fix it.
What DR's did you use?
Did you try dropping the psi?
What is your launch procedure?
Overall times including 60 ft?
These might help us help you lol

 

[JerZeyStangz]

Wow. Did you replace the clutches in the differential? I hope the guy you brough it too knew what he was doing. I have a weak-auto and I can roast both tires from the drop. I had my rearend pulled apart, and rebuilt from the ground up with new bearings, ford racing gears, clutches, and fluid. The power gets to ground a lot quicker before when I had one tire fires. Maybe its not engaging correctly. Best of luck with it!

If you recently had it rebuilt, my first tip would be to pay a visit to the person who did the work.
unless you spend all your time doing donuts in parking lots, there is no reason a rebuilt diff shouldnt last at least 50k miles.

DRs are BFG G-Force T/A (version 1, not 2: http://www.cjponyparts.com/bf-goodrich-g-force-t/a-drag-radial-tire/p/B86/). I had another thread where I talked about how I was concerned about the age of the tires (bought them "new" but they were already 2 years old from sitting in a warehouse).

After a few runs having forgotten to drop my pressure, I dropped it to 20 in the back.

Burnout procedure was to roll into the water, rev to about 2500, pop the clutch out (wasn't dumping it), and hop over to the brake. I'm new to doing this kind of burnout, so it took some time to figure out how much brake pressure, etc. From watching the one video my friend got of one of my burnouts, it looked like I was spinning both until I go on the brake, then just the one. Ended up turning nearly sideways on a few of the burnouts.
Launch procedure was to rev to about 2500-3000, pop the clutch out and go.

My best time of the night actually came when I didn't do a water burnout (2.0328 and 13.8086 @ 101.31) I did have a run (after a water burnout) that would have been better had I not missed a gear (was 3rd or 4th)...had a 60' of 1.9903. For reference, my best time on my street tires (Nitto NT555, but still not a DR) was 13.6855 with a 2.0309 60').

I did have the clutches replaced, and it was by a friend who actually works as a Ford mechanic...he's got all these awards for being this Ford Master tech or something, not a punk kid, he knows what he's doing. That being said, maybe something did go wrong. I had the gears replaced at the same time. It has maybe 4-5k miles on it since the rebuild.

Question...is this the same unit as the factory unit, or is it better in any way: http://www.americanmuscle.com/ford-racing-88-lsd-28spline.html. I might consider just completely replacing it if that's any better, wouldn't cost much more.

Oh, and I will be talking to the guy that did it.

 

[Ronin]

With the P1SC and 275 DRs, is it just time for me to upgrade to 31 spline? Everything's still NPI, so I'm only making about 285 WHP.

 

[JerZeyStangz]

Hmmm, so when your burnout they both work but when your on the brakes one engages. Maybe your on to something, one side could be stronger than the other so that wheel takes on the power of the burnout. If everything is fresh in the rear I dont see how you could get one tire fires. The T Lok isn't orginal right?

 

[Ronin]

I don't know if a previous owner ever replaced the T Lok. Since I've had it, I've only had it rebuilt.

I just watched a bit more video. I only have one run where you see my entire burnout, but on one other where you can see part of the burnout, and it's the same tire both times. Right side is spinning.

 

[OnyxCobra]

I think I'm having trouble following, I saw both it was only spinning one during the burnout and that you wen't sideways during a burnout, both of which wouldn't happen at the same time.

Also what do you define as popping the clutch and dumping the clutch?

If you were getting one tire spinning during the burnout I'm not sure something is necessarily wrong, I've seen a lot of Mustangs do that including my own in the past but it usually comes after both tires are roasting for a while. but after both of them spinning for a while I've noticed that one tire would stop, kinda weird but never thought much of it other than it's extra grippy in the burnout box. if both tires are spinning off the line or during normal street burnouts I wouldn't be too concerned, but you should be able to heat both tires at the track obviously.

It's hard to say for sure, since my buddy wasn't filming the burnouts, he got the tail end of one and all of another. But yeah I guess you're right, it shouldn't be going sideways if only one tire is spinning, and it didn't happen all the time.

But there were definitely instances of one tire fires. The trouble is it's dropping to one tire before they start to smoke, so that one tire doesn't get cooked.

By pop I mean quickly pull my foot up. By dump I mean slide my foot off the clutch to the left (something I was told never to do). From my understanding if they're not both spinning into smoke, you're not properly heating the drag radials.

Here's the best video I have of it:

My sig is factory T-lok Ford, 4.10 gears though, no line lock yet, I just dropped clutch and got on brake. My dad's 97' B4000 pick-up can spin both tires, someone screwed your diffy up good.

 

[OnyxCobra]

okay, I've never heard of popping the clutch with a car so i had to check lol. When I hear people say dump the clutch I think of just removing your foot quickly, where as side-stepping the clutch would be sliding it off to the side which yeah I would not recommend doing.



Also a hint for you, when you dump the clutch and hit the brakes i'm 99% sure you're supposed to stay in the water while you spin them, not roll out of the water and then hit the brakes. I always spin them in the water and then once they start smoking good let off the brake and let them spin coming out of the water to keep them dry. That's usually when I notice one of them stops spinning.

 

[Ronin]

So I'm just not getting on the brake quickly enough I guess. Though they don't let you sit in the water box and spin, they have you pull through it. Though I guess I could have stopped a little sooner.

But I'm not sure how much quicker I could get on them, you see my brake light come on just about immediately after starting to spin.

 

[Rice_slayer]

What kind of back-asswards track tells you to do your burnout OUTSIDE the water box? I sat in the water box and spun for like 10 seconds many times lol. They only tell guys with street tires to pull through usually...

 

[OnyxCobra]

When I go they always stop your tires right in the middle of the water, I guess it's possible tracks do it differently I'm honestly not familiar with many. You should be able to get on the brake quicker, the tires should start spinning fast enough to where you don't really move much so by the time you hit the brake the car really wouldn't have gone forward much at all.

 

[JerZeyStangz]

Hey Ronin. To tell you the truth man, your T LOK is engaging and disengaging. It could be nothing, or something. If you can do a regular burnout on the street and get them both to spin then I say your good. Because the track has vht on it so if one side gets grip its going to let the other side burnout. If its really biting you pop the rearend open and see whats going on.

 

[Musturd]

Yea I've always done it in the water box . My 96 gt did similar things a few years ago but both would still smoke I ran bias ply et streets .
And my car was just a bolt on npi with 3.73's cutting 1.6-1.7 60fts. I had just swapped carriers the night before Cus I fcked some shit up. I just added new clutches but I always ditch a shim and add another clutch on each side in the carrier. My car never one tire fires now .

I think your right on the tires not getting hot enough . Cus those 60fts should be lower. Your car seems like it should be going alot faster then this .my car would trap anywhere from 96-98mph in the 1/4 and it just had gears and a cold air And under drive pullies with off road h pipe. Are you powershifting ?

 

[Ronin]

I should clarify, they have us pull through the little ditch with the standing water, that's what I'm calling the water box. But they do spray the area past it (which is where my tires are sitting in the video). And though I've heard different definitions of power shifting, I'm assuming you mean shifting without letting off on the gas. I have not been powershifting...what RPM do you recommend doing that at?

What I really need to do is find someone on here from Phoenix who knows what he's doing to come ride shotgun the next time I go.

 

[98rocket]

I usually back into the water and before you get to the trench you stop.
Then just lightly spin out of the box to clean your tires.
With your tires being wet you can engage your burnout for a few seconds and then let of the brake while your still spinning and let them catch..
Then your ready to rock n roll..

Heres how i roll:

Also it helps to go to a pro event and watch how people who do it for a living do it..
