    Anyone run one of these on a Zetec? VW guys run these on there motors and seem to be able to pull around 5 - 10psi on average depending on pulley ratio. From the quick search it would seem that these work best on stock spec motors and smaller displacement motors. The Zetecs 2.0 displacement seems to be right on that line where performance is nominal but I know little about super/turbo charging so I'm probably missing something here. The supercharger is supposed to put out 500cc of air. Some boost estimates that I've seen on the web claim that on a 1600cc VW engine running at a 2.1 - 1 ratio driven at the crank will produce approximately 5 psi of boost.

    My guess is running a smaller pulley at 3 - 1 ratio would yield around 8 psi on a Zetec. The supercharger can run continuously at 16,000 rpm so you could run it at 5,000 rpm continuously and not damage the blower at that ratio. Thinking it'll yield around 30 - 50 hp when all is said and done.

    Subarus ran the AMR500 and have a factory intercooler that could probably work and has a small form factor so it would be easier to fit underhood if you wanted to run an intercooler with it.

    Application: to increase performance on motorcycles, snowmobiles, ATVs, VW engines, Mini Coopers, Subarus, Nissans, Toyotas or any engine under 3.0L.

    500cc/ revolution (30.5 cu.in.) With straight, 2 lobe rotors. It could be over-driven, and make good boost on a 650cc-1000cc drag bikes or larger if RPM is kept low. Or it could be under-driven for smaller engines.

    Examples:
    On a 500cc two stroke, with the blower being driven 1.5:1 with the crank, it would produce approximately 7 psi boost.

    On a 750cc four stroke, with the blower being driven 1:1 with the crank, it would produce approximately 5 psi boost.

    On a 750cc four stroke, with the blower being driven 1.5:1 with the crank, it would produce approximately 15 psi boost.

    On a 1000cc four stroke, with the blower being driven 1.5:1 with the crank, it would produce approximately 9.5 psi boost.

    On a 1600cc VW engine, with the blower being driven 2.1:1 with the crank, it would produce approximately 5 psi, but the engine RPM must be limited to 8000 rpm.

    Additional Info:
    Max blower continous speed is 16,000 RPM Before this, these were only available in Japan!
    This would be a great blower for any small engine up to 1200cc ( depending on RPM ).

    Over all length is 6.75", Width is 8", Height from inlet to outlet 5.5" The 4 bolt inlet & outlet flanges makes it easy to fabricate custom mounts for manifolds, and carbs. The drive pulley diameter is aprox. 3" but could be changed out to a cog belt drive quite easily. We have no info on what modifications are needed to mount this unit on your engine. You will need to be capable of doing custom fabrication.


    What's most appealing is the price. You can buy one of these units for around $150 - $200, If you throw in all the plumbing, custom bracketry and a BOV you're probably looking at an installation cost of around $500 if you do the work yourself. Not sure if the stock ECU will be able to handle it but if not then the cost will, of course, go up since you'll need an aftermarket ECU but from what I remember the stock ECU can handle up to around 8 psi without issue.

    One concern would be fit. Not much room between the radiator and the motor. I guess I need to grab my tape measure and start measuring. Another is the noise. It's pretty noisy so not sure how annoying it'll be on a DD.

    Turbo/Super charger guys I'd love your input!

    I have one and was going to use it on a CVH but chose not too. Then I tossed around the idea of a SC go cart or lawn mower. But I don’t have the time for it. If you want it PM me.

    as for boost, if I recall they can pull upwards of 16k RPM and if you don’t want to rev the motor high 10psi is more then doable.

    From what I know they are on the louder side if you rev them high. You could put a clutch pully on it so it only engages under load witch would make it more daily driver friendly.

    Naw! Power from start to finish for me! The straight pipe I'm running is already loud so this shouldn't be much more! LOL!

    On a zetec motor, couldn't you install this where the a/c compressor is instead. Id love to see this hooked on a car.

    That is exactly what I was going to do on my CVH.

    I want to keep my a/c.

    After taking some measurements it look like the only place it'll fit is where the radiator overflow tank is now. Relocating it shouldn't be an issue. The other issue is the a/c line. The blower will fit but I would have to bend the line a little to sandwich in the blower.

    I'd have to make a bracket and bolt it to the firewall on one side and another bracket attaching it to the alternator bracket.

    Since I don't have the actual unit I would need to see how much clearance there is to the outlet side which would land very close to the firewall.
