Competition Drag Racing With a Dually ?

[RHestand]

Just curious.

Has anybody seen or tried racing a 2 wheel drive dually?

The reason I ask is, the guys I've seen running 11 & 12 second street trucks are all using 4 wheel drive (when racing) because of traction problems using rear only.

Since 4 wheel drive is not very efficient, I'm wondering if a set 4 sticky DOT tires, on a 2 wheel drive dually, with soft suspention, would be able to hook up and run better than trucks in all wheel drive? (With the same HP & Torq specs. )

I've seen the green 1/2 ton Dodge Cummins, 2 wheel drive run with a set of 14" slicks on the back, but thats a race only truck.

Thanks for any feedback on this,

Ray

PS. I'm not wanting to get into a discussion as to what is street, and what is race. Thank You.

The only way you'll get more efficient in 2wd with a 4x4 truck is to REMOVE the front axle and drive train. You're pushing and turning the axle joints, shafts, diff, drive shaft and 1/2 the transfer case no matter if you're in 2wd or 4wd.

I have a 6 speed, and I can drop from 4x4 to 2wd mid 1/4 mile if I so choose.

While in gear and accelerating, I shift to 2wd, but I'm still in 4wd until I press in the clutch and unload the drive train. Once it unloads it allows the transfercace to release as I shift to the next gear. I see zero gain by doing this... Infact, now at my Hp level and with bald-ish tires, I'd lose traction in 4th and sometimes 5th if I'm drop to 2wd. might as well stay in for the long haul and not worry about it... but remember to try to get it released on the slow down before the turn, or expect to turn in the dirt.

Just just small diameter tires. since you have 6 of them, you'll be fine for traction


EDIT:
Well, if you get un-lockable hubs installed, then you just have the added weight of the drive train, that'll help.

EDIT 2: HA HA HA, you have the lockable hubs. then try it! get a set of slicks.

Jason,

I am speaking of using a 2wd dually with no front axle joints, transfer case,etc. To use 4 tires in the back for traction instead of 4 tires, with one tire on each corner

My thinking is maybe, with 4 tires on the ground for traction, having them all on the back with soft springs for weight transfer might be a more efficient set-up.

That is what I'm curious about.

Thanks, Ray

I was assuming you truck in your sig. Sorry

You would lose some weight and the front of your truck should be lower to the ground this way for a little better areodynamics at higher speeds. Sounds good to me.

I'll be buying a 94-98 Ram 3500(12 valve) in the near future.

Maybe I'll just be the first one to try this.

I may be mistaken, but I believe there is a guy in the Corpus Christi doing just what you are asking about. Jeff Prince of Prince Performance Diesel. I went to welding school with a guy who supposedly was a good friend of Jeff. Jacob told me Jeff has a real sleeper-a second gen 2wd dually (red and white with paint faded or peeling off) that is running low 10s! According to Jacob they like to drive around looking for unsuspecting Powerjokes, Duraslacks, Mustangs and the likes and smoke the living dogsnot out of them.



If Jeff is a member here and would like to chime in, now would be the optimum time.
