Soo... you're saying that this little 12volt fan produces enough volume/boost to blow air back out during the intake stroke? I never claimed that... Think about what you are saying...
For REAL??? so that be isn whut onna dem tangs be's lookin lak...
Well... snake oil huh...
seems I was dissed and missed it. Was looking back over this thread and came across these little gems. There's always somebody who for reasons of their own feel compelled to whip it out and start a I-know-more-than-you peeing contest. I don't know your backgrounds so I will not make the same presumption you apparently made and therefore will presume that you guys have knowledge of blowers, turbos and their function. I never tested with a boost gage (although I did have access to one at the shop where I worked at the time) I saw no need to when I could plainly feel the difference when I was sitting in the machine with my hand on the throttle which is something you can't say. Next I'll say no one on this forum has to ever spend one penny of their $$ based on my statements, that is a matter of personal curiosity and choice. IOW if you like the idea and you want to try it for yourself then by all means do so, but don't do it just because I say so, further more don't NOT do it just because someone else disagrees.
Now since you guys very apparently don't know much about my background allow me to explain; engine builder/engine final prep/engine machine work/ tool and die machinist... I was the guy that our fuel, engine, axle, dyno(transmission and engine), transmission/transfer and finally FUEL shops all came to when they needed tooling built to do their work, or ran into a problem that they had to resolve. So I'll keep this simple and not get to technical and we'll only deal with the subject at hand. How many turbos or blowers have you guys ever torn down and rebuilt? How many have you built tooling for so they could be torn down then rebuilt? Would you know which end of a Detroit blower roller is the front? Have you ever done machine work to convert low output fuel pumps to high output, or built fixtures to do the conversion? I well understand the tolerances and clearances involved in both blowers and turbos, Ever seen what a blue paper shop towel will do to a turbo when sucked into it? Ever seen a cat turbo so hot you can see turbulence ripples on it, do you know the various causes of this? Our dyno guy used to say "I got it so hot you could see through it." Do you know what an incorrect roller end clearance will cause a Detroit blower to do and how to recognize this BEFORE it does it? To all of the above I have and more. You do understand that when your intake valve is closed no amount of boost or pressure is going to force air into the cylinder? You do understand that
anything that helps move air through the carburetor and intake manifold into the cylinder -even if that is no more than rounding a few sharp corners- will increase performance, correct? And yet you say that an inline electric fan forcing air (however little that may be) through these will do absolutely nothing? Think about what you are saying...
Now that we all know that the other guy knows a little about this subject let me say this: you will never smoke all six tires with a flat head 18 hp briggs and any "blower" you want to put on it, agreed? I never made a claim that this rig would do anything other than give a noticeable gain in response and a quicker from "idle to wfo" time. We ain't trying nor claiming to pull no 7 second quarters here understand, we just want to help an old tired 18 hp flat head briggs climb up a creek bank a little better, see? Agree or not this rig did do that! I no longer own it, and probably if I dug deep into my note case, I could still dig up all the time records I made of it climbing hills, creek banks and dragging a tractor tire. But I wont bother... I no longer own the blown 950, nor any of the parts
snake oil
