Engine/Transmission (1998.5 - 2002) Methanol & water, or propane injection

[Floyd4runner]

What's ya'lls input which is better. I am ready to buy and I want the most for my money, and they cost about the same. Also plan on running it with the quadzilla someday, but I don't have it yet.

 

[johncameron]

Do you have a box or injectors yet??

 

[Floyd4runner]

I just have a supertuner, set on perf, they say it gives 70HP.

 

[DCreed]

buy a boost elbow and a set of gauges first.

Then at least 100HP injectors before thinking about anything else!

 

[Floyd4runner]

Is the boost elbow just the intake tube that came with my K/N and also I was likeing the quad because of all the gauges and setpoints. Do I just need an airdog and the quadzilla first?

No, a boost elbow fools your turbo's wastegate to create more boost. BUT, if you' don't have electronic boost fooling you will set a code and go into limp mode... .





An airdog is a fule supply system.

 

[johncameron]

Quad seems to be the best box for the buck and bang (-:

 

[DCreed]

Quad Adrenaline and Pulse with the Airdog would be great. boost elbow mounts on the turbo and can be adjusted to push more boost before the gate opens. 35psi is max. with stock turbo.

 

[Floyd4runner]

Thanks guy's, first off I was thinking of a torque tube not the boost elbow, my bad! I have been a tractor mechanic for a while, although I don't know anything about computer diesel's, thanks for the help, the main thing I know I need the airdog for fuel if I get the quad, but should I have manual gauges or just rely on the adrenaline for gauges?

 

[DCreed]

Quad is still having a problem with the fuel sender although IIRC glacier is selling an isspro replacement.

What would liquified propane do to the VP44? Am I correct here, injecting propane into the intake is in a gas state? If so what if you converted it to a liquid and injected it like diesel?

 

[Floyd4runner]

Well for one propane is liquid, you just have to pull it from the bottom of the tank. Another is like most compressed liquids I'm sure it expands about 750 times it's mass when it changes state to gas. And I bet you could here that a block away.

 

[Floyd4runner]

Also I guess my first option is to buy a stand alone fuel press gauge. I run an airtex pump right now in the factory location, is this good enough for 100hp injectors and will this hurt mileage any?

 

[DCreed]

often performance injectors raise mileage.

 

[DHayden]

personally I wouldnt get propane unless I was ringed and studded. I would go with the water/meth anyway.

 

[Floyd4runner]

Thanks, I guess I'll just get gauges first thanks.

DON'T BUY GAUGES YET!

If your going with water-meth. Go with Snow Performance. You get Digital EGT and BOOST gauges with there set-up. Get the MPG-Max system. It has two stages, first stage uses a small nozzle for low boost and an second stage with a larger nozzle for high boost. They have 6 different nozzles sizes that will take you from mild to wild. You start out with the smaller nozzles and work up as you add, build more power (fuel, timing). Go to Snow Performance.com and read what they have and then call them and talk to them. There really great people. And yes I have there MPG-Max system and it works great.

Its not the injectors that raise mileage.

often performance injectors raise mileage.

Larger injectors will always use more fuel. Its usually raising boost and changing the timing curves that improve mileage.

 

[DCreed]

Larger injectors will always use more fuel. Its usually raising boost and changing the timing curves that improve mileage.

Larger injectors allow more fuel. the increased # of holes better atomizes the fuel aiding combustion efficiency. The VP44 (via yer right foot) controls how much fuel is used. If you want mileage the motor must run as efficiently as possible. I agree it is not just from the larger injector and after a point they do the opposite. but most quality 50-100hp injectors will raise mileage 1-2mpg over stock.
