hey guys, been thinking alot about forced induction lately, as the stok compression, low end, head situation..etc etc.
and, being cheap. and simple. as always. would 2 heater blower motors...from a heating core of a car, placed in the runner of a ram air intake system, provide any significant boost to power?
this idea has been sitting with me for a while, that with a small electric motor driving a blower...or using thre squirrel cage to blow into a turbo...ways to just get around complications of the set up in the ngine bay.
any other off the wall ideas out there?
.later days.

i remember seeing a honda 90, built for bonneville, that used an over-driven air pump from a early emmissions chevy as a blower. but i don't think your idea has any credance, however.
All types of supercharger vary the speed of the blower and consequently the boost in relation to the speed of the motor. You talkin' variable speed fans?
That said, run your engine up to 3500 rpm or so and put your hand over the carb/ air filter inlet. The motor's ingesting a huge amount of air at that speed, far more than a couple of fan motors would put out. Small fans would only be a restriction. You'd need some honkin' big fans to make any sort of boost at that rpm. Sorry to be so negative, but I don't see it working.
Simple blower calculations indicate that it would require about 3 HP to drive a "fan" that would boost 480 cfm of air by 1 psi. That would be quite a heater fan motor! A typical heater fan might boost 50 cfm of air by about 3 inches of water (about 0.1 psi). A lot (60?) of these fans would need to be ganged together, in parallel and in series, to produce a positive effect. That is why superchargers (driven either by exhaust-powered turbines or by mechanical drives) were developed years ago.
For an electric motor to make any boost it would have to be rather large and even then only very low boost would be produced. The motor would be so large that it would consume more power than the extra power created by adding this small amount of boost. It would also be expensive and time consuming to install and definatly not worth the effort. Why not add boost properly using a blower or turbo set up that are proven to produce reliable power and if you shop around and do most of the work yourself can work out quite cheap.
I think this is the only one worth anything

My (soon to be) father-in-law said he hooked up a squirrel cage fan to the carb on his inline 6 back in the late 50s or early 60s and he said it made a huge increase in performance. It took a lot of monkeying with the fuel-air mixture because the system basically had to be on all the time. In that sense, I guess it's not a true turbo/supercharger, but instead continuously feeding more, cooler air to the carb.
Are you saying this wouldn't work?
Hellfish,,,,,
I am saying a squirrel cage will not work.
It will not give you any pressureized air into your engine.
The "E-Ram" will pressurize your intake charge, but only up to a certain size engine.
You can put two "E-Rams together to get more air.
They do draw massive amperage, that is why they only want you to run it @ wide open throttle.
Did you go to there website & see the video they have on there website?
It's almost like a mini jet engine.
The "e-Ram" will take off & fly away from you if you give it long enough wires hooked up to it.
:-)
go down to the local wreaking yard and get yourself a turbo or supercharger.they are plentyful(nowdays lot's of modern cars have them)and cheap and you know they work
Sure,
why not???
Just do not plan on running any high boost or high RPM, most factory turbos are too small.
Even the superchargers are small also.
My friend has a Pontiac GTP,M90 blower, and you will be pushing the blower hard to get 12 pounds of boost w/it, & that is a small engine.
Plus all those V-6 blowers are too short to fit on a inline very well.
