Consider
this:
IF someone
wants to sell
you a system
stating that it
is setup for
your car, ask
for the
computer flow
bench sheets
and printouts.
If there are
none then you
just bought a
bunch of parts
that may
work ....
or not.
Tunnel Ram Fuel Injection offers maximum torque & HP, reaction time and repeat ETs.
> Awesome throttle response
> Incredible consistency
> Unrestricted Tunnel Ram Air Flow capacity (The tunnel ram alone can add 20-40 HP)
> Response is instant at low or high rpm.
> Recovery on a Super Gas car is as smooth or as instant via your throttle control.
> Smaller or no radiator required. (cools down quicker)
> Individual port tuning to compensate for air flow variations
> We can fit FI to any size engine or manifold
> Electric solenoid not needed for staging
> Superior barrel valve, adjustability, air flow & resale value
> Alcohol makes more power and costs less per pass than Racing Gasoline.
Mechanical fuel injection offers unlimited alcohol fuel flow curves that can't be matched by
modified gas carburetors. Using our tune up, detailed instructions and expertise you can be
making laps the first day and winning in a short time.
New to fuel injection? Have no fear. We will guide you through your first steps.
We pride ourselves on providing a Fuel Injection that is as "plug and play" as possible.

with a savings in not having to run down and ship in every little piece no one told you about.
Our support after the sale has been considered to be worth more than the initial cost.
