Is there a way to make a high horsepower 2wd hook up?
- Thread starter bigbird
- Start date
Spring rates, and shock set up tire size
and air pressure is huge. your trying to transfer weight to the rear axle. It can be done in any class you just have to test and test and test. lots of notes too.

Look at Pat Spangenberg's 1966 Impala Super Sport, it weighs 4,000 lbs, it has stock suspension, and runs a 3" exhaust system with turbo mufflers on 10" slicks. He is in the 8's (1400+hp) but if he can do 8's with a less than 1.3 60' I'm sure a 2WD D-Max can pull 60's in the 1.5's AT LEAST!!! I could be wrong though. I theory is that torque is what gets you out of the hole and a modified D-Max should be putting out the numbers to make it happen.
No?
No?
I was just starting the thread up again because I was wondering why some 450 HP cars cut 1.3x 60's with 2wd. Yet there's numerous 4x4, 1000hp+ trucks that can't.
Just curious why we don't see more trucks with retarded fast 60's. We have the HP. And the tq... Well we have that too loo
The issue is the weight of the truck and chassis/suspension design. There is a BIG difference between a car that weighs 35-4000lbs and a truck that weighs 6500+++ lbs. The amount of torque we can make will actually hurt us (if you can’t put it to the ground). Big TQ and heavy truck = tires spin...
I can pretty much guaranty any of the cars you are comparing our trucks to DONT have straight axles with leaf springs and if they do they don’t weigh 6500+lbs. But EVERYTHING can be made to work with enough time and $$$$’s

Making it stick is the issue....
OK so using this as an example... A comparable dmax at 6500 lbs would need about 2000 RWHP and be able to keep traction the whole time to run a similar number.
Now do you see the problem?
I was just thinking of power to weight ratios. Like car x has 1hp per 5 pounds. Then dmax x has 1hp per 5 pounds. But yet the car always launches faster. But yes I guess weight balance really is the issue.
Dan... Fwiw they do run straight axles in the rear.

I wish I could see a d-max run low 8's maybe some day we will Trent??? but anyway that's not what I was saying, all I'm saying is its not impossible in my opinion to run 1.5 60's. The example I gave was just that.
As far as weight it weighs around 5600 lbs , I am still figuring my truck out , and havent made enough passes with out making other changes to get very far , have no clue what its capable of but best to date for me is 1.52 , I any Allison truck will be limited IMOP due to the low first gear ratio , I usually make the 1-2 shift before i am even past the 60 ft mark ,also the to get the power it takes large turbo setups that take some time to hit full power, was working on ways to fix that along with getting the TC locked sooner this year with good results , just didnt get much testing due to other issue's , I guess well see what this year brings .
I dont think you will see me do it but cant say how hard i will push the truck this year , I have plenty of big idea's still but no were near the budget as this last year was a grim reminder
