Default Re: 1969 Camaro Cowl Induction Hood Functionality????

[ QUOTE ]
I've always been curious just exactly how functional the 1969 Camaro Cowl Induction hood assembly was under actual test conditions over, say, a regular 14 X 3 open element air cleaner. Has anyone ever run back-to-back drag strip tests with the Cowl Induction systemfully functional or even just wired open vs. a regular air cleaner? I know that's supposed to be a high pressure area at the base of the windshield.

My BB came with the SS hood originally but, like most Camaros of the era, someone added the cowl hood. When I returned the engine compartment back to stock appearance I install the standard open element air cleaner correct for the SS hood. The engine would suffer from detonation at anything much over 3500 RPM and sometimes lower.

I've installed an original cowl induction air cleaner a few years back and now the engine can rev to over 4500 before it begins to detonate.

I'm assuming that it is the cooler air that is making the difference.

There was one down side to the cowl induction air cleaner. It has raised the under hood temperature and my GM starter solenoid was suffering from excessive heat. When I shut the car off, I had to wait for it to cool off before the starter would work.

I solved that problem by installing a mini starter. Works great every time.
