Smoky Burnouts

[Old Smoky]

I have seen in several posts people claiming there pickup could "easily" spin the tires (on pavement I assume), or could lay 50 feet of rubber. I find this kind of hard to believe. Though, I could be wrong.



I'm defiantly not one who hot-rods my Cummins; I am a fairly conservative driver. But I am sorry to say that my 86hp 1986 Subaru hatchback could win in a burnout competition hands down with my Cummins. I am not complaining, I am happy with the way my Ram runs, but it just doesn't seem to be that impressive. If I burry the go-pedal in the carpet from a stand still (2nd gear), it blows some smoke and starts moving, but not too quickly. It doesn't even start to break the tires loose.



I have turned the power screw in one turn, adjusted the aneroid, switched to a 16cm turbine housing, slightly advanced the timing, and added a K&N air filter. The pickup is a '92 4X4, 5-speed, 3. 54's, and 285/75/16s.



Is it because of the gearing? Not enough mods? Or, is this the way it should be? I hope to make it to BD dyno day to see what the numbers are. Just curious.

Mike, If you make it to Dyno Days you will be a true believer



Dyno Days is awesome

My truck's no ball of fire, but it does move off the line pretty good.



I had 100 to 200 lbs of scrap plywood in the bed, which actually improved my traction quite a bit.



In the first video, I powerbrake it mildly. Just to the point where the rpms are up to the point where the converter begins to make the engine work a bit.

In the second, I just banged the pedal down as the truck is moving forward slightly.

In the first one, the truck swings sideways a bit and continues to spin both tires until I hit the point the governor starts to cut down.



In the second, it spins about 8 feet or so, but it stays going straight. In both c ases, the tires spin just after the truck starts moving. In both cases, the truck's in motion before I nail it.



Please note the (lack of) billowing clouds of black smoke...

Thanks for posting the videos Power Wagon, but they where invalid or expired. I get the point from the description. Sounds like a real "go" machine. I know I don't have the injectors, exhaust, timing advanced as far, or as small of turbine housing as you, but I would think my rig should perform a bit better than it does. With the mods I have should it not be able to spin the tires? I would think even a stock rig should be able to.



Have you dynoed your pickup? I am curious as to what the numbers for my rig will be, if I can make it. It’s about an 8-hour drive form here to Abbotsford. Sure sounds like fun.

The videos use realplayer.



If you have trouble getting them to download, do a right c lick on the link and "save as" and put them some place you'll find them easily on the hard drive. AFter they download, double click on them to run them.



If you don't have real video, let me know, i'll try to make some other form and upload them.



I can make mpegs as well. I'll make one and upload it as well.



EDIT:



mpg made.

Try that one.

Honestly, until I did the turbo, thre was no chance of even squeaking them. after the turbo, with no fuel turned up OR injectors (fuel is STILL not turned up), it would spin the tires.



It had to be just right and you had to power brake it heavily, but it would spin them for a short distance. Injectors made a world of difference.

Burn Outs....

How much does the transmission have to do with all of this? Most of the guys that talk about burnouts have autos... My truck is a 93 W350 w/ PW injectors, 16 cm, K&N, freeflow exhaust, but no pump tweaks YET and a 5 Spd. . Although I have not tried real hard, I have tried and my burnout experience is the same as Old Smokeys (nill) ...



Any insight?

A non-tdr guy I converse with regularly sent me a link to his page...



He does a little powerbrake video... but he has hard tires and makes 'em squall. My tires make no noise because they are soft compound, I only know it's spinning because it tends to go sideways. I can feel it.



Here's Milburn's:



http://www.cdc.net/~warhawk/cars/diesel/diesel_burnout.mpg



And his page:



http://www.cdc.net/~warhawk/cars/diesel.htm



He says his truck can easily take a duramax or PSD to 80 mph by several truck lengths and in the 1/4 mile as well.

 

[KMC]

Nice vids, so is an auto the key?

 

[Power Wagon]

I would think it would be a whole LOT easier to do with a manual.



Rev it up a bit to get the turbo spinning, ease the clutch up to the point it starts to pull good, drop the "go" pedal and then the clutch. .



Instant tire spin



I've noticed the guys with the 16 housings do not have the solid low-end grunt you get with the 12. I think that's probably the largest difference.

Nope, no dyno. I'm guessing it makes a whopping 160 perhaps, at the rear wheels. If I'm lucky.



In all probability, i'm losing 30 to 45 HP in the auto. I should have about 200 at the flywheel.

 

[KMC]

Thanks Powerwagon, seems it is my 16cm and my technique. I'll go try again! With the dual rears it shouldn't be to difficult. I guess I get to gun shy and don't want to really hammer hard for fear of breaking something... Guess, I should have a little more confidence in the old Dodge, huh?

Being a burnout expert for my highschool days i will tell you how to do a burnout with your truck. although i have only done this a couple of times with my truck. My truck is mostly stock and believe me yours should be able to to this too. place truck in second gear. place your right heal on the brake. then place your right tow on the throttle. apply the brake at the same time bringing the rpms up to about 1700. gently let the clutch out to put some load on the engine for just a couple of seconds this will build some boost up in the turbo. Then dump the clutch while holding the brake with your heel and the throttle with your toe, for as long as your desire LOL or your tires do for that matter, then what i do is let off the brake and floor the throttle with the tires still spinning and it leaves a nice pleasing black mark LOL. a side note besides the smoke the turbo really sounds kewl spooing up with that load on it while starting the tires to spin.

My truck - see sig for mod details - would spin the rear tires without power braking - but not real excessively. BUT, when towing our 5th wheel with about 1200 lbs total extra weight over the rear wheels, has spun the rears a few times when I took off too aggressively from a dead stop - on pavement!



NOW, with the additional half-turn on the power screw, will EASILY break loose the rears without braking - and would probably burn ALL the rubber off them if I *did* power brake...



And that is with the indicated 3. 07 differential, and the US Gear switched into OD - for an effective rear ratio down around 2. 5!



Not too shabby for what I consider a fairly mildly modded truck...

 

[Hutchew]

Yeah, brag about it now.........

but wait till you shear the pinion off the rear end, like I did last month, 300 miles away from home. I don't believe I'll be doing any more burnouts in my truck (for a while, anyway).

 

[Old Smoky]

Got my turkey today!



Well, Cummins Cowboy, I tried your technique. I just wanted to see if it really did work. The verdict is, I don’t know. It sure builds boost! After letting out the clutch I sat in one spot for a second, then took off. Something was sure giving for about 50 feet. But I think it was the clutch. The test road was covered in rubber, and it was dark, so it was hard to tell if I deposited any rubber from my bald tires to the asphalt. When I backed up to check the results I could smell the clutch. Being as persistent as I am I gave it another try, with the same results. I don’t know if it is like Power Wagon said, "My tires make no noise because they are soft compound, I only know it's spinning because it tends to go sideways," and my tires where spinning, and didn't notice it. I suppose if I had a spectator who could confirm the results I would have less confusion. But I don’t think the ol pickup really cares for this activity. Besides, I'm sure if I had stayed any longer the old farmer who lives about 75 yards down the road would have come out on his front porch in his union suite yelling profanities and waiving a shotgun above his head, and I didn't want to witness that. So, the mystery goes unsolved.

burnout

After the POD's I can smoke my tires on any surface anytime. That is with a dually with a power-loc LSD in back. And this has been confirmed by a spectator. Need more power eh?

I originally planned to, but the wife's schedule leaves us almost no time at MM. She doesn't get off work until 7:30 AM on the 2nd. And then it's 14 hours drive. Leaves us just fri and sat, and we ahve to be back on Monday. Ugh.



So I guess not.
