My suggestion would be to throw on a bigger bottom turbo. what kind of boost are you hitting with those twins? what kind of fuel supply pump do you have?

 

Wouldn't he benifit from converting to a SRW for pulling?

Another vote for front locker. More traction never hurts.

 

have thought about converting to single wheel........what turbo should i be looking at? I think that the bottom turbo is a s4000 but not sure.....I have the turbo wastegated at 65 psi....

 

try a big brother or phat bastard, I think youve got enough fuel to light it, but when you do, watch out cuz it will rip. I've got a friend runnin a silver bullet and phat bastard in his race truck and that thing is crazy.

 

What exactly is a Fhat bastard?

 

Isn't that a contradiction? =P I thought 6 wheels was an advantage, since the front and rears all follow different lines.

Does 132 mm inducer mean anything to you? Some of the bd twins use a 66 =\

 

id put 33x14.00x16 boggers in front and 33x10.5x16 boggers in the rear. and lower gears like a 5.13 or 4.88. if you can get the boggers to dig and keep spinning there hard to beat.

as far as converting to a single wheel. i donk know if one has a distinct advantage ove the other. but it has to be easier on the rearend. only turning the weight of one wheel and tire. in my exp anything you can do to reduce un sprung weight will help.

 

I.I. lists the PB as a 95mm inducer. Still huge.

I think you'd have to spin a CTD up the NASCAR rpm levels to spin a 132mm charger!

I bet the turbine for that thing would work well in a power plant

 

I've seen a couple different turbos called phat bastards. The S510 and the HT4C II's is probably a hybrid of some kind.

Either way, a hole lot of turbo

 

Ask Justin

I was thinking it would work well in this case because each tire would have more contact pressure and therfore (theoretically at least) "bite" better.

 

Go to www.industrialinjection.com and check out thier turbo page. The phat bastard is a turbo they sell, well a huge turbo they sell. They tweak the wheels and shaft a little, but they are big. The prices on the website are retail so dont get sticker shock. pm me if you want one ill go talk to shane and brady! (just down the road)

 

In a motocross race, you try to put your rear wheel in a rut at the gate as it seems to have more traction than prepped surface dirt or a filled in foot packed rut. The only way to get a hole shot is to do this. I know nothing about pulling but I would imagine that if the rears track in the same rut as the fronts, you will get more traction. Side wall bite for example, and more firm dirt on the bottom for the mudders to bite into. Now this could be like sand where you want bite to launch but floatation thereafter. Now the 1 inch difference between on top and in the rutt could play a major role too and cause less sled weight on the truck and thus less traction. It seems like all of the serious pulling trucks use soft balloon like wide tires that dig a little but ultimately float and swell up with rpm effectively changing the gear ratio and allowing more effective wheel speed.

 

After all that, I've changed my mind twice and think that it all depends on track conditions as to which setup will have an advantage, single rear or dual.

 

I assume you mean Pourindiesel, because I don't know much about pulling.

In fact, I typed all I know about it below:

 

I figured you would know the math behind contact pressure theory I had... I have read the theories, but they are kind of like your posts, I think I get it, but am not 100% positive I understand!

I don't know much about pulling either, other than videos of other people doing it with their trucks are cool
