Alcohol injection & new needs

[Rod Grosvenor]

As promised: the report on the effectiveness of alcohol injection. First, after being on the dyno, even the toluene could`nt keep the engine from bumping into the knock sensor at higher rpm. The pattern smoothed out and was obviously better after the alcohol was injected. I`ll use far less of this than the toluene (at almost $9.00 a gallon, it`s a good thing!!!) The MSD unit does`nt start the boost timing retard until 15 lbs. of boost; needless to say, I`m about 1/2 of that. I now can increase boost from 7 to 10 lbs. + once I have a boost gauge and a controller. I did`nt really pay any attention to the info on the previous, but now need some input. Any info regarding the BEST (and most accurate) boost gauge would be very helpful. Also, is there a website for the Hallman manual boost controller? If not, who has the info to contact them? The driveability and increase in smoothness and power is obvious even with the stock NA fuel & timing maps. The dyno results? 155 hp at the front wheels/160 lbs. ft. of torque-can`t remember the RPMs. The guy that installed the injection said with the right boost increase & the alcohol, an easy 200/200 is readily possible. Remember, this is from an NA motor that started out @ 130 hp at the flywheel. Believe me, this thing pulls so hard it`s amazing. I`ve had 2 other people drive it that said it`s much faster than the numbers would indicate. Sorry for such a long post but I promised to update & now have the need for the 2 aformentioned items. Thanks---ROD (AZ.)

Rod,

I gotta ride in this thing!!!! It sounds like a complete monster!!!!

Rod the other trick is to make your pipe to the alcohol injector run
a number of loops around the header pipes with copper tubing. This
creates a finer mist being injected, therefore better atomisation.

And another is to add 20/80 water/alcohol but experiment with these
figures. The water allows some in cylinder cooling benfits and also
keeps the combustion chamber free of carbon build up.

Note: make sure you use Distilled water.

You can get about 90 degree temperature drop by using water in you
injection.

I'd recommend an electronic HKS:

HKS lists for 279.97USD on their site:

There is a reason they're so damn expensive; they're the best.
