| Subject: | Cold Air Induction |
Is anyone familiar with cold air induction on a 540? What is it, what are
the advantages and disadvantages, what's the cost, where can get the
equipment, how difficult is it to installation and what modifications are
required, and most importantly; is it worth it ?

David:
We have a cold air induction system for the parallel head and angle head
540 and 580. Our system is a lightweight magnesium sump and plenum.
The system has seamless stainless intake pipes, and the system is
shipped complete with everything you need to install the system on your
engine.
The engine becomes forward facing induction resulting in greater inlet
air pressure (ram air recovery effect), and if you get a larger throttle
body, the increase in air flow is substantial. The system also removes
the inlet air from the oil sump, rerouting it through the separate
plenum. We see a 15-20 hp increase with the cold air system on stock
compression engines. These numbers are verifiable on our dynomometer.
This is the cold air sump used in virtually all experimental competitive
aerobatic/race parallel 540 engines in use today.
The biggest disadvantage is that with more air and colder air, you are
going to burn more fuel. You may also have to make cowling
modifications for the system on your airplane. Hope you find this
information helpful.

David, Not sure if it=B9s worth it or not. I raced a fellow that had
10:1pistons, Barrett cold air induction, no air filter and a Sky Dynamics
fancy exhaust. I=B9m running a Barrett engine with 9:1 pistons, filtered air
and nothing else but attention to aerodynamic detail and I smoked him in a
flat out race. If you=B9re going for speed, fair the plane well and make it
straight.
