Fritz Kott's supercharger

[voodooracer]

 Been admiring this unit and how he used it since the Bub meet and his pic in Cycle World Jan '05.
 Any chance someone could check with him to see if he could be contacted for tech info?
 Sure would like to look into using this on my CR500R dragbike.
 None of the v-dub sites have been helpful, one even locked a thread about it cuz it was just a smog pump and of no use as a supercharger even after I posted 'bout Mr. Kott and his record-setting flathead!
 Thanks in advance for any help.

Not familiar, are you sure it's a smog pump? Some of the smaller Aisin, AMR, Ogura blowers look similar.

  Thanks for the reply, panic.
 Just repeating from the afore mentioned article and what little info I've gleaned from VW enthusiasts. Best guesses so far have been air pump off late air-cooled or early water-cooled Cal spec only, which is why I'm hunting info from the man that actually is or has used it, namely Mr. Kott.
 Any sources of info for the ones you mentioned would also be appreciated.

I can't find any reference to the bike (although normally aspirated descriptions exist).
AFAIK there is no smog pump large enough to give positive pressure in an engine as large as a 45.

If I see Fritz at our meeting tomorrow or the next El Mirage meeting I will pass on that someone is looking for him............I haven't seen him in awhile.

 Thanks guys for the posts, guys, especially the links, panic. Had seen the 1st one, but the one with the mini-bike is a hoot.
 Hope you do get to see him, Scott, and hope all is well with him. Thanks for trying.
 Only reference to the blown config. is the lead picture (full page size) by photog Jay McNalley in that Cycle World article (am looking at it this moment).
 Fritz is standing straddled over the seat, helmet in hand; almost full left side shot, bike is covered with salt; and that little blower is mounted to the primary cover directly in line with the crank, a K&N type filter clamped to the inlet at the bottom and what looks like that aluminum heat stove pipe plumbed between the the outlet on top and the inlet side of a very large (and unfamiliar to me) carb.
 The caption reads: "Fritz Kott knows how to have fun. He showed up at Bonneville with his flat-head Harley KR, set a record, then supercharged it with a Volkswagon air pump and set another record."
 Wish I knew how to use computers better. I've come across detailed pics of this thing, even the patent # 3,275,225 issued to the Midland-Ross Corp of Cleveland OH Sept 27, 1966, but don't know how to even copy and paste stuff much less upload pics and links and whatnot.
 I'm gettin' too technical for the general chat area. Really do appreciate any help with this quest. Am including my e-mail address here. If anyone can help please e-mail or pm and I will be happy to supply phone # or will use my dime to call if you provide a phone #.
 Thanks again,

 Many thanks to all here who replied and especially those who helped get me the info I have been pursuing for so long.
 I'm really impressed with the sheer volume of knowledge here and the willingness to help a total unknown to this community.
 Kudos to the admin. and all the members.

have ya considered a turbo charger....?

easier to find with much better results...

Correct me if I'm wrong, but don't I remember that the rule that requires blowers (however driven) on motorcycles to create boost -- stems from a bike of Fritz's and the records it got in "blown" class -- without really making any boost?

[joea]

jon, how are ya gonna enforce that rule.........ie what is it doing
at mid track.....?
...
does anyone verify that the things hanging off exhausts out there
now...so called turbochargers.....create positive pressure....??

anyone even look inside of any of the housings (supercharger or turbocharger) to see if there is apparatus
that looks like it might make boost...?

Hard to go over 240 with a 1000 without a little boost isn't it Joe?    I guess in classes where there is an open, you could do it without a little pressure.

Some time ago I saw a small engin bike with a smog pump on it and the tube between the pump exhaust and the engine intake removed. The rider told me he picked up a few mph that way compaired to conected. He got his open record.

[Seldom Seen Slim]

Joe, I don't know how we're to "prove" that the blower is indeed, blowing -- but Rule 7.J.7 does say "...and shall pressurize the intake system above atmospheric pressure."

...AFAIK there is no smog pump large enough to give positive pressure in an engine as large as a 45...

I'm in contact with a guy who tried to make such a pump work on an Indian 741
(in a rather strange blow through configuration / set-up)







...never got to work properly; indeed one of the problems were that
it simply did not 'deliver' enough... even for such a small engine (500cc).
