P/N #1179R - Super Power Vent |
POWER VENT
by Doherty Machine
E.C.S. Engineering is proud to introduce the Power Vent by
Doherty Machine, to our inventory of racing products.
The Power Vent (a crankcase ventilation system) is a superbly
machined addition to any stock or custom built motorcycle. The Power Vent is not only
impressive looking, but also has a definite function.
- Increases horsepower
- Improves throttle response
- Stops oil leaks caused by blown gaskets
The Power Vent comes in three models, two for street use...
and one for big-inch drag racing... from gas to nitro. The Power Vent helps to stabilize
the rings, which in turn helps to seal the rings and control wear, which helps to make
more horsepower. It also helps to control oil leakage on non-sealed moving parts, a must
for all fuel engines.
