I was over a friends house, the same guys who i am building the mulcher with, when i thought of the Bulldozer From Hell. It would have a steel and aluminium frame with four wheels mounted on common axles running from an east-west mounted diesel with chain drive from the gearbox to the rear axle. But in addition to the mobility gear, I was thinking of having a mower frame mounted with blades facing the rear of the machine, the back covered with steel plating and having a small intake chute running on an angle to the blades to make a side firing wood chipper that could run off a hydraulic pump on the motor. That pump would also run a high-flow water pump on the side, a PTO and a set of hydraulic rams lifting a roller on the front. The roller could also be exchanged for a dozer blade as well. If anyone could lend their knowledge and/or experience, I would really appreciate it.

Yeah, but i want to put an intergrated Pioneer/Venom/Response/VDO Dayton stereo system in it and i dont think many bobcats have one of them. Hey, does anyone know if a Jabsco type Impellor pump would provide the hydraulic motor for the pump, wood chipper and hydraulic rams for the PTO and the Blade with enough pressure? If not, could anyone suggest what would because i do not particularly want to be covered in hydraulic oil from a burst line. And would an automotive aircon belt swith (the ones that allow the belt to turn them but dont engage the compressor) be able to be mounted onto the Jabsco pump?

How y'all doin? Reviewing my BFH plans, i had some thoughts on a N2O or water-alchohol injection system. With a Nitrous Oxide system, would that increase raw torque and horsepower or just revs and horsepower? I think a NOS would be very amusing when using the mulcher. Would it help when moving and lifting heavy loads that the motor would be struggling with? If anyone could help or donate a NOS, i would love them heaps (not really).

Uh... NO2 with a bulldozer would probably be a bad idea. Construction equipment needs reasonable power for long stretches usually, and nitrous oxide is really only for very short bursts. It's also very hard on the engine and will tend to foul things up. Unless you want to regularly take apart your engine and clean it, I wouldn't recommend a nitrous system for something like that.
For more general horsepower, go with a turbo system, which is a very common feature for construction equipment.

Yeah, i see your point. I don't particularly want to be servicing the engine every couple of weeks so i guess i will leave the NO2 system out of the picture. With the turbocharger, do you think that an intercooler is necessary? Now, for a diesel motor, would a water to air intercooler be a more effecient option or is it wiser (and cheaper) to stick with a forced air intercooler? I had thought that a water to air intercooler would be more suitable for this design because the Diesel motor would often be under a lot of strain at low speeds so air is not going to be moving around the intercooler fins that much, but a fan-forced radiator coupled to a Water to Air intercooler would be the best bet.

Will you be using a diesel engine or gasoline engine?
If you are using a gasoline engine, you will probably want the intercooler to reduce knocking somewhat.
Diesel, it probably wouldn't matter except in power output.

Aaron would probably have some good feedback for this. If he doesn't weigh in on this topic maybe email him?

Probably diesel. Petrol (gasoline) engines just don't have the grunt and torque in a small space like a diesel has. Isn't an intercooler a necessity? I thought that it would be best to cool the air as much as possible before it hit the manifold. Maybe I should drop Aaron an email, he probably has the knowledge to help out.
