Ed. Note:
Wady Hamam or Pro Mod Wad as he is
known in the sport as drag racing's main
nitrous Guru. He has been involved
in nitrous oxide injection almost
from its inception especially with
the Pro Mod division.. He is originally
from the Buffalo, New York area and
has been involved
in all types of racing from flat track
motorcycles to fuel dragsters. In
his wasted youth he even raced a fuel
funny car powered by a blown and injected
small block Ford! He and his brother
campaigned a front motored Top Fuel
dragster and lost a race against Don
Garlits at the now closed Niagara
Falls Dragway. His advice about nitrous
problems is highly sought after but
he is hard to get to. He has agreed
to answer one question every couple
of weeks for Drag Racing Online readers.
Email your questions to: promodwad@racingnetsource.com,
and he will answer the question he
finds most intriguing.

Pro Mod Wad,
Most racers use gas injected with their nitrous, but does anybody run a gas
motor and inject alcohol with the nitrous? How would the tuning differ from a
gas and gas combo?

RC,
Over the years I have worked with several
racers that have run a race gas engine and alky/nitrous
combination. The results are ALWAYS frustrating!
It seems that the slightest weather condition
change affects the alky/nitrous tune up dramatically
and it's very difficult to get consistent runs
with this combo.
The better way is to run the engine on alky
and run the nitrous with race gas as very good
results come from this combo. Much power is
available from an alky engine and it is easily
tuned on the nitrous side with race gas.
In the last couple of years some racers
with multi-staged systems have had better luck
with ethanol alcohol in one of the stages as
the ethanol has characteristics of both race
gas and alky. It seems to make good power without
excessive heat and follows more closely to a
race gas tuning jetting map. But they only seem
to use it in one of the stages--no more than
that.
I wish I could give you more info on this
type of fuel, but if you do some research you
may find the info you need.
