Hi-Po ran 11.91 at 117 MPH. Lets break things

[Hi-Po]

Had a great night of racing tonight. Many 11 second runs, and beat other Fbody's that I had previously lost to. Car was running very strong, I was getting some decent 60's, MPH was decent.

Last run, Went to do my burnout and the car seemed to lug down. Had a gut feeling something was wrong. At the end of the run, smoking like a SOB. Didn't drop any oil on the track thank god. That was my 7th run, and the guy I usually race in a nice Camaro blew his transmission.

We both obviously decided to call it a night I beat him all 5 times tonight.

My car still ran, rough. I pulled out of Milan, and the rear end was popping around corners. Great, damn Trutrac is toasted. Going with a spool next time, screw the Tru Trac. Lasted one year of drag racing, not up to my expectations.


So, I ran 11.90's all night and it cost me...

One motor (slight knock, tick)

One Moser Tru Trac. Obviously popping around corners.

Time to build it bigger. Future plans, 370 or 402/8 CI with a F1 Procharger, and a damn spool.

Congrats on a great et....but sorry for all the carnage to get it. Like you said, good time to build a new setup.

What were your 60' times?

Sorry to hear that man....

1.70

1.69

1.74

1.89

1.71 etc...


Im more upset about the rear end. I dont want to go to a spool really, but I cant be replacing these Tru Trac's after a racing season.

[Hi-Po]

Sorry to hear that man....

I did put quite a few pass's on this car this year. I would say 40 at least. Not that anything should have broke, but I had a great timing breaking it

Have to expect to break things when you go to the track at least once a week for a few months.

I know this is probably an out of this world question, but what is the warranty on these things from Moser? Any chance of going back to them to see what they would do for you, if anything? I mean these rear ends are supposed to be made to take some major abuse, correct?

Guessing you saw how my axle is leaking again. I want to just fix it myself, but I don't know if I would be voiding the warranty. Bob told me to come out to see him in the early spring to get it fixed as I don't have a whole day to spend going out there right now.

Those are pretty good 60' times. I forget if your car is A4 or M6. Also what size and type of tires you running at the track?

If there's any way you can investigate as to what failed in the rearend....because I wouldn't think a tru trac would break like that. Was there any strange noises coming from the rearend prior to racing? Dumb question, but was the gear oil filled proper? What fluid do you use? Just food for thought really. I wouldn't go to a spool if you're going to street drive the car most of the time. Spools are for the serious racer IMO.

Congrats on the times and taking it to those that previously beat you. That had to be a great feeling having all your hard work pay off like that. Real sorry to hear about the breakage though.

For what it's worth, I am looking forward to reading your posts on whatever upgrades result from this.

How far of away is EPP from you? If its a decent drive I would say thanks, but no thanks. Replacing that seal is an hour job.

M6. Mickey Thompson ET Streets Radials. Fluid was just checked about a month ago when I replaced an axle seal. Its perfect. If I remember correctly I put Valvoline 80/90. I dont know what else to do. These Tru tracs are crazy expensive. Over a 1000 dollars IIRC. If another TruTrac fails, Ill have almost 3500 into a rear end and still need to buy another center section. This car will always be a street car, but the strip is very important. I have a little while to ponder this decision, as its a very big and important decision. I have read many bad stories of Tru Tracs and the 1/4 mile. I also hear alot of people doing just fine.

Thanks. Me and this black guy have been battling for weeks. He's a stalled auto with a 228. Great guy, but it felt great to pull him by a car 5 times tonight

The next project will no doubt be based around a F1 procharger. With the power levels I would expect with a F1 and a 370/40x... I dont see Tru Trac being up to the task.

Another dumb question...What moser rearend do you have? Also did you put the little tube of differential lube in? Using petroleum based gear lube is much better than synthetic...helps to absorb some of the shock when launching. I was asking about any noises because if the lash wasn't set right on the ring & pinion...it could cause early fail.

I agree about your statements of Tru Trac....I think they're a quality part. Sadly, like everything mechanical, it's going to break at some point. If it were me I'd get another Tru Trac and just mark this one up as a freak issue. You'll kick yourself later if you go with a spool and have to deal with it on a regular basis. Just my .02 on that. Maybe talk to Moser and see if they can do anything for you. Who knows, worth a shot anyways.

It was not synthetic for sure. I put the recommended amount of additive and had a good breather system on rearend. After about 20 pass roughly, it had a slight whine at 70 MPH. Nothing severe at all, alittle music and you couldn't hear it. When I got the center section, it still had fresh paint marks on it. I also took it to Caterpillar where I used to work and had the specialty shop check it out. I loved the Tru trac on the street for sure. Drove like a stocker.

I want to ride with a buddy who has a spool or maybe a locker for a week and see if I could handle it. I would love to have a unbreakable spool back there at the track.

Definitely must have been a freak breakage then. Just like in nascar...sometimes those things just break and it's just a shame. Easier for them to deal with it since they've got huge budgets to work with.

I guess if you can "experience" a spool car for some time, that would be optimum and definitely help make the decision. Let us know how that goes.

[Mr. Luos]

My TruTrac clunks around corners a bit.
Not actually the rearend...but the rod-ends on the LCA's binding.

Good times though man.

Really? I assumed the Tru Trac was on it way to being wasted as I have never heard this clunk before. That would be awesome, but this is a pretty hard knock when turning.

[Mr. Luos]

Mine catches people off guard....

But it is the LCA's. Everything still works fine with the rear.

When did it start making the noises? My noises happened right after my last pass.

After beating the shit outta the car.

Hmmm, Well I can only hope for that. That would be awesome.

[1986camarojoe]

mine makes all kinds of noise but still works fine.. usually a nice clunk when slowing down for a corner
