Competition How does your Turbo Diesel run at the drag strip?

[Steve St.Laurent]

Finally got back into the 15's again this weekend in St. Louis (was in the 15's first time out this year and couldn't get back there since) - best was a 15. 929 @ 88. 38 mph (launching in 2wd). I had a run that was on it's way to a 15. 7 but it was during the eliminations and I was dialed in at 16. 1 so I slammed on the brakes at the end and went through the traps at 16. 104 (!) @ 74 mph and won the round. For a great video that Eric took of me doing a burnout there check out http://gltdr.org/videos/stevesburn.avi

 

[Todd T]

I ran a....

15. 47 @ 85. 85MPH this run should have been faster, but my dumb a$$ forgot to turn off the speed limiter.



my next best was at Steve's door handles, I ran a 15. 59 @ (hold on) 93. 32 MPH. it burned out a little



P. S. Steve and Eric, I had a great time this weekend, and look forward to seeing you next time. with a new clutch.

I have improved my time a little, it ran a 16. 15 @82(???) a few weeks ago. I just barely got into 5th before the finish line.

I am also at around 15. 8 at 89 mph. 60 foot times are what killed me I belive. Around 2. 9 seconds Also did not have the top end power, must be the stock turbo! I see from turbonatr's post he ran a 15. 06 @ 87mph. I was 2 mph faster, but . 7 seconds slower. I that just because of my weight? 7200lbs, 3. 54 gears and 285/75/16 tires? Just trying to figure out whats up.

 

[Steve St.Laurent]

You should be faster than that with an auto and those mph's. My 60 ft times are 2. 4 when running in the 15. 9 range (had a 2. 3 but that was the run I hit the brakes on - should have been a 15. 7 run it looked like). What was your launch technique (boost and rpm)? I and several others estimate that auto's should have nearly a second advantage in ET but roughly the same MPH numbers - yours are both the same, launch technique could affect that. I weigh 7400 lbs at race weight with me in the truck, BTW.

[Swamp Donkey]

4-6 lbs boost is what I leave with. Not sure about rpm's but no more than 1500. No wheelspin most of the time. Shifting at around 3000. (GSK) I only made 2 runs and they were done with a vericom. To much snow right now to go and check again. It will keep me thinking all winter and I might come up with a 15-20 lbs of boost in 4WD launch! That will fix that pesky 60 foot time.



One question, are 14's possible with the right driving technique?

 

[turbonatr]

I leave in 4WD, otherwise, the tires go up in smoke for about 300 feet even from a dead idle launch. In 4WD, my truck will run 1. 90-1. 91 60ft. all day long. There was also a 20mph head wind the day I ran that 15. 06 at 87mph, which explains the slightly low trap speed, not to mention my stock converter was screaming for help! The proper torque converter and valve body will no doubt put me over 90mph.

 

[HoleshotHolset]

If you want a good ET... . get those 60-ft. times down. Shave a tenth off the 60' and you can get upwards of 3-tenths on the ET.

MPH in the 1/4 is a good indicator of power, but it takes traction to make the ET..... which is why one car may run a 10. 97@125 and another may run 12. 32@127... it's all in the traction.

As of Nov 11th



13. 60 E/T

99. 28 MPH



I want 13. 5 and 100mph.



Discovered a traction problem even when using 4 wheel drive... .

Going To Slicks

Anybody got a faster time then 13. 1... ... on street tires... ... 2wd???



I'm converting to slicks now. It is futile to try to get quicker since I can't get it hooked up with 2wd.

 

[HoleshotHolset]

I imagine with a dually and the right backspacing on the rear rims... you could fit some really fat slicks.



Get 'em good and hot and let her rip.

1 st gen times

17. 4 at 79

shifting at 3000 but 2500 4 to 5

next time ill go 2500 rpm shifts



anybody got a faster 1st gen dually 4x4?

 

[WAYNE]

15:52 @ 86. 6 MPH with a 2. 25 60', soon to improve that!

 

[Swayse]

14. 59 @ 91. 96 mph done in west Texas at Penwell race track. People laughing at us, until we started running. Then not laughing anymore, doing this

 

[HWhitaker]

TRACK TIME

First time out did 14. 5 then 14. 25 last 14. 3 around 90 mph.

 

[Gary C]

Check my sig: 1. 91 best 60'



Sorry I have been hiding, Fast Women and Car(New Viper) has been keeping me busy.

 

[HoleshotHolset]

WAYNE,



Time for some slicks and/or other traction helpers like ladder bars, etc..... make that 60' come down to a 1. 8 or a 1. 9 and you'll get a much better ET...



My $. 02 worth,

Matt

 

[WAYNE]

New times as of 11-28-01

14. 37 @ 94. 30 mph with a 2. 16 60ft.

With the new power , ladder bars may be just what the truck needs.
