Devilsown Methanol Alcohol Water Injection - View Single Post

Terry Syd · 05-14-2008

Dvldoc, I've had a further think about the pre and post nozzle injection issues. If someone in the Phillipines was going to run both a pre and post-nozzle injection, I'd really appreciate the dyno charts on swapping the nozzles around - ie: DO1/DO2 to DO2/DO1 using both straight water and alcohol blends.

As I understand it, the cooling in the compressor section performs one function and the water dropplets into the engine cylinder perform another function. Thus, the swapping around of the nozzles might allow us to see the relative merits of both functions.

Also, the use of straight water may see a different response through the turbo. Perhaps the alcohol blend through the turbo may decrease the evaporation rate of the water through the turbo as the alcohol will boil off much more rapidly. What result this has on the power curve would also be of interest and might suggest an even larger nozzle in one of the locations.

I'm looking forward to your tests.
