Q45 Techs/Experts look here
Im planning on putting a leaf blower on my intake. Need some advice on this. How much cfm to make 4 psi. Is a leaf blower capable of this kind of boost on the Q?

that i know of, a leaf blower only blows. think of it as a normal fan. a turbo or supercharger is an air compressor. that is where the intake pressure comes from. since the leaf blower is just basically a fan, it won't have all that much power to compress the air nor the design to compress the air.
my statement could be flawed but i'm pretty sure it is correct.

well since the leaf blower is gas powered (at least i'm assuming so) you won't have to worry about alternator drain nor any power drain at all since its power is fully independent. now if it were electric you would need to run a power inverter so that you could supply the 120 volts ac or whatever voltage it would be (i'm not too knowledgeable on home electricity).

if you know how to set up different gear ratios and had a powerful dc electric motor you could get a turbo, take the turbine off and the turbine wheel. Get someone to machine a gear with a sleeve on it so that you can keep the shaft in the turbo by using the stock nut that goes on the shaft.
| | | | | | <- gear...|| || <- sleeve...|| ||..../\.... | shaft(don't mind the dots)
Make a sort of gear box that will bolt onto the center section to contain your gears for some lube. Make the box to where you can slip the shaft of the motor in and bolt it on. Have a gear machined to fit the electric motor and the figuring out the gear ratios so that you can spin the shaft at around 100,000 rpm (that will be one crazy gear ratio depending on how fast the electric motor runs). The gearing will be pretty crazy because even if you got an electric motor that produces max power at 10,000 rpm you're gearing would need to be 10 revolutions of the impeller to one of the motor (if I'm thinking it through correctly). You'd have to do some math to figure out the best gear ratios per the speed of the motor at maximum power and what not.
With this setup, you'll have the instant boost off the line like a roots style s/c due to the electric motor's crazy instant torque but also have full boost throughout the rev range kind of like a turbo. Depending on the power output of the motor you get you would most likely have to upgrade your alternator but it would be a sweet setup nonetheless.
I just now thought of it because I got bored and had nothing else to do.

Remember the GT car several years ago with the 4-leafblowers motors that would suck trapped air from beneath the ground effects. They worked with the speed/brake activated spoiler. That thing would flat out hug the ground with a mild vacuum. The concept was immediately outlawed. Now if I can find a good use for that yard waste shredder.

Imagine if you had a throttle sensor which activated a belt driven blower that sucked air from underneath the front of the car while the same throttle sensor activated a leaf blowing motor (connected to ducts of course) in the trunk...
Why can't we have a couple millionaires on these boards? Damn people, go waste some of that money!

And unworkable, I'll bet. No way to suck enough air through a radiator to generate downforce.mtcookson wrote:I believe the Ferrari F40 or F50 actually uses the radiator fans as a downforce mechanism. Those large spaces in the hood are for air passage ways to the radiator fans. Pretty damn cool if you ask me.
Jim Hall did it on his Can-Am (now their was a great racing series!) Car (the Chapparal 2f?) by mounting an extra engine (V2, I think) to power a large fan to evacuate air under the car. It was outlawed before the auxiliary engine had a chance to fail in a corner and send the driver to certain death when his downforce disappeared. It was essentially the world's first (and still the fastest) parking lot/roadway vacuumer.

Good memory you have, I couldn't even remember what type of car it was on. It was a gas to watch that thing approach a turn at an incredible speed and then scrub all that momentum in a split second; between the brakes, the spoiler, and the Hoover it was an amazing choreography while it lasted.
