There are many alcohol kits
available, but if you are serious about
reliability and
repeatability it is advisable to use a regulated
system with a
return line with at least 3 nozzles for a better
spray pattern. A Methanol/Alcohol Injection Kit similar to
mine offered by Joe Tripodi ,will be compatible with the MaxEffort
in the respect that upon sensing knock, it optionally will turn on
another nozzle along with the "Fuel out" capability that
allows you to run way oversize alcohol jets and trim the fuel back
as far as you want.
Also, testing has shown that a
deadheaded non return line system does have its place, but when you
pump 2 times as much alcohol into your motor as you do gas, you
better have the regulated system for reliability. Deadheaded pumps
sometimes groan when they are hot and have to start against boost
therefore they don't
come up to speed all the way. The pump
associated with a regulated system runs all the time, and has a base
pressure of 40 pounds which climbs with boost.
If you use
straight methanol to replace gasoline, then use VP
brand with their oil. If you use rubbing alcohol, then do not use
any oil. You will observe some people running high timing with
alcohol and pump gas, my advice is to keep the timing at 18 degrees
and back the car off the "edge" a little.
Experience also shows that you MUST totally rely on the knock sensor
with alcohol and pump gas, forget EGT and 02. Knock can be
unpredictable. If the motor gives out false knock, then either run
straight race fuel or don't get on it. The folks that argue this
point will probably never see 30,000 miles on their motor, and
realistically, probably not even 20,000. I have been doing this since
85 and have made the same mistakes that I see going on
now.
The motor I have now has 120,000
miles on it with a TA63 turbo, and has never had the valve covers
off. Follow the rules. Spend the extra bucks for the regulated
system, rely on the KR sensor, keep
the timing down, and back it
away from the "edge" a little.
There are some exceptions to the above rules. Guys that run
the
higher rpm cams MAY make less cylinder pressure, but because
the frequency of events occur more often, they end up making more
horsepower. This, combined with smooth polished heads, let some guys
get away with murder with excessive spark advance and a deadheaded
system. The stocker the cam and the cruder the heads, (crude heads
can provide hot spots in the combustion chamber) the more you have
to watch the detonation. It is just not going to be
predictable vs EGT with pump gas.
Below are some
pictures of the MaxEffort Methanol/Alcohol Injection
System.
*** The two nozzles on top
are water/alcohol in the up pipe from the
intercooler. At the
base of the up pipe, on the pulley side, there is a methanol nozzle
that triggers upon detonation. Located below the MAF, in the top of
the intercooler side tank, are two methanol nozzles side by side
mounted on the horizontal plane. All nozzles are pointed into the
flow of air. ***
