New Magnacharger

It's how the bypass actuates that is different. On most superchargers the bypass merely controls boost pressure for spikes things of the sort. The Magnacharger uses it turn the boost on and off based on throttle position.

I won't argue with you because I have no idea how the Magnacharger works but... My TVS doesn't make any boost just driving around so it wouldn't be putting stress on the motor either.

LOL. This is quite funny! The Magnacharger boost bypass valve works exactly the same way as the bypass valve on any other screw type blower. It is operated by vacuum, pure and simple. There is no 'special' way you can use the throttle to make it work or not work! On light throttle, when there is high vacuum, the valve is pulled open and boost is bypassed. As soon as you step on the gas, the vacuum disappears, the valve shuts and off you go. The only difference between the Magna bypass system and the others is that the Magna bypass valve is internal.

I know this because I thoroughly researched this blower before I bought my TVS. I seriously considered buying it as Stage3 were doing a killer deal on it at the time. You can find this information on Mgna's web-site if you can be bothered to look for it, that's where I originally read it.

I'm not certain this is completely true, or that Walter is necessarily incorrect about this. Looking into a Roushcharger for my F150, I noticed that the bypass valves in most Positive Displacement Supercharger kits for the modern 3V engines aren't 100% vacuum operated like they were with the old 2V or 4V engines. According to Roush, although the specific function of the valve is vacuum operated, the bypass valve operation itself electronically controlled by the circuitry that controlled the charge motion control valves that are not reused and tossed aside with the installation.

The bypass valve event can actually be set to open, or close earlier throughout the power band based on the torque sensing parameters of the ECU tune and not necessarily based on the amount of vacuum, or manifold pressure present.

The major difference between the Magnacharger and a Twin Screw like the Kenne Bell, Whipple, FRPP is that the Twin Screw is continually compressing the air under all levels of operation, even while not pressurizing the intake. This actually contributes to higher ACT driving around under vacuum and most likely limits the amount of initial timing present. This is probably one of the major reasons Roots/Hybrid based kits seem "snappier" around town. The Mangacharger, TVS and any of the other "Roots/Hybrid based" blowers on the other hand aren't compressing the air under vacuum and thus ACT's remain consistently lower during general driving.

mm...how much boost you running?

easy power with a smaller pulley and a couple more PSI.


Exhaust...long tubes, o/r mid pipe...anything like that will give large gains with a blower


gears would be pointless really

You could probably pick up a solid 30 RWHP with l/t and an o/r mid pipe with that blower

IMO gears are not pointless. They will be money well spent and a must mod for your car, even with the supercharger. Not just saying it, I have done it.

Well I'm sorry too then!

Seriously the reason why I said that is because the Magnacharger from what I gather is the only supercharger that gives you the option of not building boost at all. The bypass valve closes at a certain throttle opening allowing the blower to make boost only when the gas pedal is pressed a certain way. That enhances driveability especially in heavy traffic and in situations where boost is neither necessary nor recommended.

Other superchargers don't have that option and can be a handful to drive if you have a lead foot.

My Vortech V2 has a bypass valve, as well, and I can stay out of boost as revs climb as long as I'm not heavy on the throttle. Build any manifold pressure by pushing the throttle down enough, and the bypass valve closes off to build boost. I thought most blowers & turbos had bypass valves. Mine came standard with the V2 kit.

Does anyone have a CAI on their MagnaCharger?
