Look at this: http://www.snowperformance.net

Apparently it's *not* in the same category as electric turbochargers, spiral exhaust tips, or tornado air cleaner inserts. In diesels, it's supposed to lower EGT's and raise HP significantly by cooling the air charge post-intercooler with water & methanol.

I used this sort of thing in a Dodge Charger I owned once, but I never thought of it for a CTD.

Anyone have comments -- theory, quality of parts, or experience with it?

I'm running at a hair under 400 hp, but I tow loads at high altitudes in the Rockies during the summers, long grades up to ten thousand feet & off-road. I could use a reduction in EGT's.

Matt's site says you could run his system on the road for 500 miles between "fill-ups" if I'm reading it correctly. But I also thought there'd be some benefit from shooting water/methanol as low as 12-15 psi, more as you go higher. I was thinking of getting a five-gallon tank and mounting it somewhere. I'll call Matt & talk to him. I'd assume he's interested in tapping the diesel towing market.

Thanks -- I.

(1) KingofDodge -- Apparently you can use window washer fluid or fuel de-icer effectively -- both contain methanol. The system supposedly lowers EGT's considerably by cooling the air charge. See #3 below. Seems mostly useful for competition, but with a five-gallon tank, say, it could be useful for towing or long grades.

(2) Jim Fulmer -- Larry over on TDR wrote something about how water droplets have different compression characteristics than diesel fuel, and that this system could blow out the head gasket in an engine with stock compression. I didn't understand your answer -- I read you to say that this had happened to your CTD. Can you clarify?

(3) I queried Matt at Snow Performance about using this system for towing at high altitudes with the CTD. He said:

"For your truck, I recommend the stage-2 ( $ 399)with the variable controller if you are not over 40psig boost. the controller is adjustable from 5-30 psig. Over 40psig, I recommend the stage-1 ( $ 299 + 19.95)with our high boost upgrade ( 15-60 psig activation). I recommend using one 625 ml/min nozzle with the pump set at 150psi and utilizing your stock windshield washer reservoir ( approx 1-gal) - you may need an auxiliary tank depending on re-fill intervals - 1-gal at 625 ml/min will last approx 8-min of constant injection. Mounting in the air horn should be fine. We have seen no deleterious effects to boost gauges and fittings also mounted on the air horn, doing it this way. This kit will drop your EGT's significantly for trouble free towing and will up your power. The kits are in stock."

Thanks for the clarification, Jim. I'm assuming you were injecting way more than the 625ml/minute that Mark recommended to me. I'm going to give the stage 2 system a try in a couple of weeks.
