Yeah we all know its a scam

I wouldn't mind running propane again but I think my compression ratio with turbo is too high, if I did use propane I would only be able to use it in say the 2-6 psi of boost range.
I have considered running water methanol at lower boost.

I think I would be better off running water methanol since it would enhance the temperature differential between both the hot and cold reservoirs. The evaporation of the water methanol makes part of the cold reservoir cooler, then when the diesel is injected and lights off the methanol, both burn off and help make the hot side hotter.

Actually, your compression ratio is fine with boost. Go over to Heath Diesel's site and see what they are doing. Try 30 psi boost on top of 22.5 to 1 compression, water-meth injection, twin turbos, NO INTERCOOLER. All on a 6.2/6.5 based engine.

The race truck gets 30 mpg on the highway. Does over 160 mph. Stock cam, heads, intake manifold, etc. Good stuff.

I just buy products from heath, never read his stuff.
Looks like I am about to start.
I have herd heath likes to fill there high power blocks with block filler up to the bottom of the water pump inlet holes. I thought about adding some block filler (since I did build the engine up from a bare block in my living room) but didn't want to add another 30-50lb of weight to the engine. I would rather have 30-50lb more load capacity or get up a mountian that much sooner.
I have herd the 6.5T doesn't do well on water methanol. Only thing I can think of is there timing could be too far advanced on a stock engine. Heaths 2bar blown diesel could be running less timing than a normal engine.

True on the block fill, and the engines don't run hot at all. The pump that he uses is an off the shelf Stanadyne DS4, and they use their software upgrade with a higher rpm limit, nothing that a customer can't purchase themselves.

The engine can handle water/meth just fine.

There's an article in Diesel Power about the LSR truck that Heath built.

Like I said, good stuff.

I looked up the diesel power article on heath, they said he was running pure water, to the tune of 1 gallon of water for every half gallon of fuel burned.

I will be using the 6.5 turbo block with 6.2L heads and fuel system. I wont have any of that PMD nonsence.
Also I have no problem sticking well below the 4,400rpm limit mechanicly built into my DB2 injector pump.

I thought every one that was a diesel modder knew of propane/natural gas fumigation.

It is very unfortunate that I cannot buy a decent adsorbed NG tank here in the US, they use them on mopeds in foreign countries but won't sell them here except for low volume torch applications.

An adsorbed tank would eliminate the need for a $3k pump every year and eliminate the high cost of NG cars.

Absorbed gas? like the way you dissolve Acetylene into acetone for storage and transport?

Not exactly, NG will "pressurize" at low pressures in the presence of large amounts of activated charcoal.

Adsorbed Natural Gas Technology

G-TEC Adsorbed Natural Gas Cylinders

Sounds simple enough, gas cylinder + active charchol + mild compressor.
Any idea what the start up on this is?
With the "american way" its $100s of dollars for the tanks and the high pressure boost compressors run about $3,600 (last time I looked).
