Hi, All!

Has anyone thought of making a supercharger from an old waterpump?

I'm thinking of it right now. Is it going to work or......?

An automotive waterpump? They won't make any pressure.

A waterpump from a house seems more likely, if they can be run dry without damage. But they're really heavy.

Domestic waterpumps use a ceramic seal where the shaft enters the housing - if the pump is operated dry the seal will overheat and burn.

So It won't work :( :( :( :(

I've tried something else but it gave only a momentary boost.
I was testing an electric air horn to see if it would make ant difference in
performance but didn't satisfy my "expects".;-)

Anyway....
10x for the quick replies

After seeing the leaf blower video I'm really surprised that no one has yet to try using one on one of our cars. Theres enough room under the hood to mount up a stripped down leaf blower and run some piping...

Probably won't give huge gains, especially up top, but it might pick things up at the bottom end *shrugs*... just figured I"d throw that one out there for Mr. Ness

Yes, I've read about the leafblower thingy;-)

I was thinking, maybe two or three air horns with lines fitted directly
in the filter housing(1.3 SOHC TBI engine), will give a momentary
gain approx. 2 or 3 seconds at WOT.

I'll try things and report it!

what about using a blow dryer to force air. just take out the heating element and there you go. and electrical just get a power inverter and a switch to turn it off and on. remember just an idea.

haha i thought of something like this before too haha, except using an airtire tank (for pumping up flat tires) you can get them at crappy tire here in canada or im sure any other automotive place. run a fatter hose from it with a fitted fitting on your intake (closer to the throttle the better the air gets there and colder) run a valve on that piece of the hose (from tank to intake) then fill up the tank to about 100psi (usually hold over 100psi like 120 -130psi) tanke it for a rip and open the valve. :wink: kinda like a supercharge effect but your not drawing any power or anything for the charge from the car too. just have to refill the tank every run down the track hahahaha.

thats something i thought of before

the hair dryer won't work.

A - the volume is just too low
B - it doesn't build enough pressure
C - running it off an inverter powered by the car itself is counter productive... it will require more horsepower to power the hair dryer than it could make (which it couldn't do anyway)

The air tank won't work either, not unless it's a huge tank filled to hundreds if not thousands of psi. A regular portable air tank that racers use (and that are available at auto stores) is probably only enough air for maybe 10 to 20 revs at wide open throttle, so you'd use up all the air after traveling 6 inches (actually, probabaly more like 1 cm).

well, then how about some of the old "smog" pumps,
like the one that "just happend to fall off" :wink: of 2 of my
old toyota celicas the one witht he 22r's. they were
used to pump air into the exhaust for some reason.
I was thinking if you could mount one (belt driven)
then reduce the pulley in size to spin it a little faster,
dont know since im not a mechanic :( but that is what
just popped in my head (or circut breaker) :shock: when i
read this post.

The smog pump pumps air into the catalytic convertors to reduce emissions. I've seen them used on small engines like Honda or Briggs & Stratton single cylinders but it wont do squat to your car.

somebody did an internet artical somewhere about putting a very large air pump from a full size pickup truck on a small bore commuter car, and it showed positive results.

But for the amount of work it would take, why not just bolt on a supercharger?
