They're air pumps.. not timing gears.. the clocking isn't that important. I assume it would change PSI output between the two slightly but nothing that would be likely very noticeable or adjustable even... Especially when they tee or hat together into the TBI.. I'd be more worried about slippage on that alternator.
This is creative as can be, and also inspiring.. keep it up, and I hope you got yourself a fire ext close by these days. Be safe!

well, i welded a "support bar" underneath the blower plates, got rid of 1 tensioner and replaced it with an idler to run a single belt...... painted it all up and put her in the car for a test fit.
i already knew the hood wasn't going to close, but everything else is spot on. couldn't be any happier.
I'm really liking this. It was almost warm enough here to start working on one of my vehicles.
I'm a little late to the party, but I agree. The slight difference in speed will only result in one blower providing slightly more air than the other. The PSI will be even since they're plumbed together (I assume). My concern is whether the V belt would be able to provide enough horsepower to run the blower and whether or not the alternator would slip with the original setup.
sorry i didn't tell you guys.
I have it all worked out to where a single belt will be used all driven by the crank. Problem fixed :D
I got rid of the passenger side tensioner, replaced with single idler, added another idler right below alternator and now it's capable of running just 1 belt. :]
bump!
I know its a bit of a dead thread, but I'd love to know how the intake piping is routed...
