Corvair Corsa 140/4spd

Since the body and interior are "as good as they're gonna get" at this point, I moved to the engine compartment. Been replacing all the rubber grommets and accordion gizzy for the accelerator at the firewall. Plus, of course, a top of motor tear down including carbs, yadda yadda.
.All the bearings in the fan, alternator and idler pulley are in excellent shape and silent. Good news there.
According to Fitch (look him up), by dumping the stock air cleaner and going to four separate units, plus re-canoider the PCV system, along with advancing the timing by 3', it's worth 15hp. I'll take it. Sounds just like a China bike mod!
In addition, since it's a quad carb setup, I bought some exhaust adapters and Dremeled them to custom fit. VIOLA! Instant velocity stacks! The real reason for this is to tap the PCV into one of the primary carbs, but what's the point of synching all four carbs if only one has a stack? The way I see it, anything that gets the airflow straighter to the venturi cluster is a good thing.

I also converted it to an electric fuel pump. All the new replacement mechanical pumps are garbage. They make a bypass plate for the mechanical pump, so I rebuilt and prettied up the one I have. All it does is route fuel now.

The Corvair Guru's say "No rubber under the hood for fuel!"....so I did everything in metal line. Word to the wise, I bought steel line which was a BITCH to bend and flare. I'd try aluminum next time around.

One of the Guru's also pointed out, "Your fan looks cut down". Sure as heck, it's supposed to be 11.25" and has been cut to 9.5". The same fan mod Yenko did to his cars. Supposed to take less HP to spin it. Someone really put effort into this. You simply can't buy one and only certain people will attempt to cut magnesium. I guess someone REALLY wanted this mod.
