electric superchargers

ok. i know theres been threads on this before but i just wanted to know if anybody has bought one and tested it and seen any results. anybody find a site where they tested a leaf blower? i know alot of people don't like them but i've seen some that claim to produce up 2 3 psi of boost. i don't think they do but might. just wanted 2 see if anybody has tested them instead of just saying it won't work.

I use a leaf blower, and a pretty damn strong one at that for starting my gas turbine engines. They produce about a pound of thrust which is just enough to start the turbines up from a dead standstill, but just enough to bring it up above a stall. IMO, a pound of boost is better than nothing, but I feel it is not enough to warrant the price they command for such a device for so little actual results. If you really feel that you need a turbine, go put one in! But there are other considerable factors that come into play when you do so. Like building a stronger bottom end, bearings, pistons, rings, wrist bearings and pins and to keep it from detonating from being too lean, new fuel injectors with higher flow rates (Matched to flow within 2% of one another if you are super serious about it) and a completely different ECM to make it all work. Doing it proper and building it to run hard reliably turns out to be a challenge. Bolt on tinker toys like this in my opinion alone are just not worth it in the long run. They rob so much power to generate that pound of thrust, it almost becomes a no-gain situation. Remember, electrical accessories draw from your alternator and battery and your engine has to work harder to overcome the additional load.

No, no,and no...waste of money.

before you just say its a waste do you have any results to prove it is? any testing that you've done? plus the price for it is $40 for the blower abd converter is $140 or close to that and you can always use that converter for other things when the blowers not in use. plus i think that even if it gives you .5 boost. .5 is better then a vac the the motor nromaly has on it.

I can pick up a real turbine from the scrap yard for $150, fabricate my brackets and pipes for pennies on the dollar, and THEN you would see a real improvement starting at 5 to 9 pounds above ambient pressures. Half a pound of thrust for that kind of dough is just....silly. But that's just my opinion. The problem is, you're not going to find anyone wasting time and money on this to research it all that deeply. That is such a minimal ROI it's *almost* laughable. But try this....

Instead of blowing that kind of money on that setup, one can easily get more than a pound of boost at WOT on one of these engines using a 12v battery powered leaf blower. Put a micro-switch on the throttle bracket that will spin the blower up from a fused power source tapped off the battery. You can do it for less than $40 between parts stores and the pawn shop for a used blower. Do you own research this way before you spend the dough on the "professionally packaged" kit adfter you have decided that it is worth it. You won't be so sorely disappointed when it *doesn't* work as expected and more than a $100 richer when you ditch the parts.

i thought about that. the only thing i've heard that would cause a problem is that one the CPI motor theres no mass air flow which could be a problem but the issue i see is the map sensor. there are 3 types. i think i have type one which messure only vac. and the other two measure boost. i need to try it with what i got but i bet i'm gonna need another map.

waist of time and money. have i done it personally? No my schooling has tought me better. Have i ever worked on a vehical with one? Yes, no gain, in fact imo at wot, it causes a drag on the moter thats tryin to suck in air
