s.c.o.t. Blower?

[Swedester]

so I´ve been offered this blower that just came of a running engine, so the blower is in bolt on and drive shape,what could such a thing be worth?I´m thinking flathead dragster here,he-he! http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif

[Flat Ernie]

They're not worth much anymore - everyone has already done it. The new thing is NOS & turbos.

But tell ya what, just pack it up & send it to me - I'll pay the postage! http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif

hm,think not,he-he,are there any parts available for those these days?

[Crestliner]

If you decide your not interested, I am looking for a flat motor blower.

If the case, front drive gears and the rotors are in good shape; all the bearings are available from any good bearing supply house.

If the blower still has the original "V" belt(s) drive I would suggest switching to a "rib" belt. (the "V" belts have a habit of stretching unevenly)

Make sure you have the "pop off valve" with the setup; otherwise there is a lot of machine work involved in replacing it.

[Swedester]

the rotors and drive gears are fine,and it been running last year on a 4cyl engine, so there is no intake and such that I could use for my project, just the blower,the guy want me to bid something, and I have no clue, I just said,I don´t need it, but if it´s cheap...I´ll buy it.

[Digger_Dave]

Without the intake manifold and pop off; you will need to do some tricky machine work.

I have seen a stock flathead intake manifold sliced off just above the intake runners of a three carb manifold. (just below the carb bases) Then welding a base for the blower (1/4") out of aluminum. The base would need to be milled to insure that it's flat. (the blower base is parallel to the bottom of the intake surface)

The pop off will need a tube from the main plenumn of the manifold, with a spring and a way to adjust the tension.

A lot of work; unless you can track down a flathead manifold and pop off valve.

If the deal is for just the blower; my guess would be about $300.00 USF. (and thats providing the case isn't worn; there is no way of restoring the case)

Next, there were several different sizes I believe. What is the length of the bare case? (in between the back cover and the front drive) If the case is shorter than 8 3/8" then it wouldn't do much for a flathead.

[Swedester]

thanks, I´ll check on the lenght.! http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif

Can you still find these for $300?

Not likely. If it is incomplete it's not worth much. (no manifold or pop off or drive pullys) Because I have one, I would offer that much to get the case.

Plus if the one he is asking about was off a 4 cyl. it would be a smaller sized blower, (not confirmed) and not any use to even me.

A good one with ALL the accesories and in GOOD condition, can run between $6,000.00 and $10,000.00 USF. There is talk that someone is reproducing them in the US and go for about $12,000.00 USF.

I only suggested $300.00 as a bid because the seller didn't want it anymore. Remember he is in a different country.

It would be to me.
Swedester, if it is a small 4 Cyl one, and you dont want it, could you try and snap it up for me?

[Chopt 34]

That is the price range I understood these were going for. I have not heard anything of the repro SCOT blowers. Any other info?

[22 track]

Thanks for the explanation, Digger Dave. I would think $300 was too cheap to be realistic even for an incomplete SCOT set up for a smaller engine. I believe even the smaller versions were adapted to flatheads “in the day” although maximum pressure was limited. I have an article on overhauling the SCOT I previously sent to some on the HAMB. Let me know if anyone else would like to see it.

[Chopt 34]

22 Track,

I would be interested in reading that article you mentioned, do you have a scanned version?

[Swedester]

well, I put a REALLY low bid on it yesterday,and he wasn´t happy,but he still didn´t give a price,so we´ll see how it turns out.

[Swedester]

well, I finally got a price,it equals to 266$,and I´m getting pic´s and the lenght tomorrow I guess.

[Flat Ernie]

I'd say snap it up & flip it if it doesn't meet your needs - should be able to unload it on eBay fairly easily...

22 track; was that the one you had on a PDF?
I think I was one of those who you sent it to. It was in Street Rodder. (April '76; by Oddo??) Already got the replacement bearings!

Swedester, if the case IS 8 3/8ths inches long; and you decide not to keep it, I would like to make an offer. My present case is a bit rough.

[22 track]

The Street Rodder article was the one. I was concerned some of the bearing numbers might have changed by now.

[Swedester]

one of you guys sent it to me, but the files were empty,no articles.please send again,I´ll be interested to read it.
I actually know of another scot blower too,I´ll look into that one also if it might be a "good" size.

22, All but two were still "on the shelf" using the same number.
I deal with a large bearing supply house and they had no problem "crossing" the other numbers.

They said that all they need to know is, the type, (roller, ball etc.) OD, width and ID and they can mach just about ANY bearing!
They even suggested subsituting SEALED (permanently lubricated) bearings for two of them.

A TIP: If the front seal for the drive rotor is showing signs of wear on the shaft, a very small "cleaning" pass can be made. (on a lathe) With a new seal with slightly smaller shaft size ID (they can be had in about .005 inch increments) this will insure against oil "leaking."

Another TIP: The gear case uses a small vent, (to prevent presure building up when the oil heats up) that normally just "breaths" out side air. I found that after a while the gear lube gets pretty dirty, so I adapted a tiny FILTER to the breather. A small pleated paper fuel filter seems to do the trick.
