Big tow #1-7ft x 10ft flat deck trailer (est 1500lbs empty, it was a redneck special) with a k440(360lbs) a zx600(450lbs), two beds, two dressers, all my tools (500lbs?), and the rest of the random crap when moving. So at least 3,000lbs.

Big tow#2-Uhaul box trailer that was bigger than the car (I don't know how they let me drive off with that one). Full of furniture but it was a giant sail slowing me down.
So were you running a straight methanol injection or water/meth? What type of system did you have and was it overly expensive consumption wise? I will definite be running waste oil so some fuel costs I can live with. Gotta get my filter setup put together though. We've got plenty of oil available here. I can run 80/20 wmo/rug a lot.

I made my own system, I think it was 5GPH. I still have the manifold somewhere in my shed if you want it (we welded in a sprayer bung on each runner).

100psi pump is $60-$100, Iv'e gotten them for $20 used before.
Then you need an on/off valve, pressure switch, tubing, fittings, etc. (Probably another $100)

So now you've got an extra system to maintain and you're at least $200 into it...or you could save that money for a $1200 pump.

Fuel economy tanked when towing I'm sure, I didn't even check. Was a straigt pipe with the 2056v, and never went past 1150*F (It's been a while).

You can adjust or remove your alda, that sets the pump to deliver "12psi" worth of fuel. There's a document on superturbodiesel forums detailing the tweaks you can further make. use OM616 probably has a copy too.

DON'T pull the rack limiter, just adjust it as needed. That was an early mistake a lot of us made.

So is it straight meth or washer fluid? A k-jet CIS pump pushes 85-90 psi I've got a bunch of them. What type of" sprayer" we're you using? I would be interested in the manifold possibly. K-jet injectors would be ideal for this too I think.

I ran 49% alcohol, 51% water using a shurflo 100psi pump. If you run anything higher than 50% alcohol you're risking pre-detonation under compression.

www.Mcmaster.com part # 32885K731 (general use spray nozzle, 1GPH @100psi x5)

If I did it all over again from scratch I'd run a single large nozzle upstream from the manifold. The 5 port monster wasn't the best design, especially since it was built into a short runner manifold.

You add a valve and pressure switch to keep it controllable.
Pump->pressure switch->valve feeding the sprayers. This way you can have your lines pressurized and then flip a switch to start dispensing. If you just have the pump plumbed directly to the nozzles air will get in the lines and they don't start as evenly.

Ok. So it was sort of like a nitrous system, on demand only. Not a throttled ful time supplement. the CIS gas injectors would be perfect for this since they are sealed up to 55 psi or so. I'll have to flow test them at some point when I'm screwing around. I'd love to see some dyno results with a diesel meken pump and the right parts. If I can go over 200hp and 300+ lb ft I'm sold. But a bigger turbo and meth injection for the time being to achieve similar power would be great.

Oldsinner111 I think used propane switched in either by putting a switch at the end of accelerator travel or at a certain boost pressure.

Propane is risky because:
-If the engine is hot enough, you can get detonation
-You can get ticketed for using non-DOT tanks on the road

I'm not a huge fan of the "power added" idea like nitrous or propane or meth for that matter but I guess it's only used for acceleration or on a steep grade? Not pumping extra fuel cost while cruising right?

I finnlly finished moving all my stuff from my old shop to the new one( big thanks to Fonzi )not gonna say my move is finished cause there's lots of setup and trashing of some stuff. i just looked at the ax15 next to a Mercedes manual and it's way bigger. I think some serious tunnel rearranging wil be done.
