Blue head Hanno
 

I asked this in the "Question and Answer" section, and was told to ask here....I recently ran across something strange on the big auction site. There is a Hanno engine for sale with a blue head. Was/is there such a thing? I thought the Hannos had a red head.

RE: Blue head Hanno
 

actually you should have taken this query to the classic pattern section[X(]. there's a lot of us over there who own hanno's. it states that there has been a dave shadel piston and liner added to it, maybe the owner had the head recolored? i would ask the seller.

RE: Blue head Hanno
 

That's probably a good idea. Should have done that to begin with, but some sellers will come up with all kinds of tales just to sell their product. I figured I'd get a more accurate and honest answer here.

RE: Blue head Hanno
 

I don't know weather the Hanno ever came with a blue head from the factory or not??

I have seen a blue Hanno head in a photo before...It was in a for-sale listing of used parts from two Hanno engines...There was one red head and one blue head in the photo..I tried to buy the parts but they had just sold...I bought a Bolly EQ-62 pipe from the same dude though...

Oddly enough this guy was in Canada too...Humm..Maybe someone re-anodized some heads up there??? I defiantly wouldn't rule out someone stripping and re-anodizing as that would be pretty easy to do..

I have also seen photos of blue Hatori pipes in the past..I'm not sure it was the Hanno pipe though...

Maybe it's possible O.S. did a limited production of blue heads?? I can't really make out the serial number but I thought it looked like a pretty high number (6***)...

The engine appears to have the correct pump and carb...If it's got a Shadel piston/liner and new bearings the only other "Hanno specific" item would be the crank (He seems to know his stuff so I'd imagine he put some decent stainless or ceramic berings in there)

One other detail is the head appears to be correct...It's a machined aluminum head which is included on the Hanno engine -vs- a cast aluminum head of the standard RF-P...

Any more Detectives out there?? These are just my observations...

I like the blue head allot...

Well, I ve never seen or heard of a blue headed Hanno. I suspect a reanodized head, but then again I haven't seen a real space alein either, are they out there? I think not, prove it to me and I'll change my position.

Did the Shadel P/L make it a .67 cid? If so, are our recent Nelson P/Ls gonna transform our .61s into .67s?

NO! Just measured the bore on a Nelson P/L and it is 23mm.

Just done a quick search on Hanno spares within the OS website, here's a new head http://www.osengines.com/parts/images/27704030.jp, and it's Red!

I guess that if OS did a Blue version they would also do the spares, seems not!

RE: Blue head Hanno
 

I got a reply from the seller. He says that the head was "purpose made" . He didn't seem too happy with my question. I wasn't trying to put down his item. I was just curious because I had never seen a blue head Hanno. Thought I might have run across something special....had even considered bidding.

RE: Blue head Hanno
 

we could always unload on him about it and really irritate him.:D

RE: Blue head Hanno
 

I got the feeling that I'm not the only one asking questions:eek:

RE: Blue head Hanno
 

Oh,

sure! If the engine came from the Great White North, that would be entirely normal. The head is actually red but it appears blue. Typically that's due to the temperatures up here. :D

I like that though... A Hanno that would complement my blue head S40 would be peachy!

RE: Blue head Hanno
 

I responded to the seller's message, saying that I had not meant to offend him, and that I had considered bidding, because I thought I had found something special. The rant I got back from him was a bit confusing, to say the least. He said that his engine IS special, and that I was welcome to retract my bid, and that he might even buy it back.....jeez, I haven't even bid...and now I don't think I will[&o]

RE: Blue head Hanno
 

Scott,
Sounds like the dude's a little embarrassed.......[8D]

RE: Blue head Hanno
 

Wasn't trying to embarras the guy. Just wanted to know what he had. That's the very reason I asked here first. I figured I'd get a much more honest and unbiased answer from you guys. I'll contact him tomorrow and see if he's calmed down a bit. I'd just as soon not bid if he's still ticked off. Hard to have a positive transaction when it starts off badly. A wise old gentleman once told me that a good run is better than a bad stand...;)

RE: Blue head Hanno
 

The Hanno was never produced with a blue anodized head. I asked the seller about the Shadel piston and sleeve regarding the displacement increase. Specifically, I asked if the engine case had been bored out to accomodate the larger bore of the 'purpose made' (larger displacement) piston and sleeve. He replied that the engine had not been bored out and the piston/sleeve were 'purpose made' which to me sounds like 'one-off' special attempt. I may have to call Dave directly to satisfy my curiosity, but I really (I mean REALLY) doubt that Dave would have made 1 or 2 custom piston/sleeves for him. SInce it was actually Henry Nelson doing the work, he may have done it, but not for cheap!!
Personally, I would love to see the engine and take it apart. If the serial number really starts with a 6*** then it is a MKII version. I'm just not sure I want to commit ~$200 or more to satisfy my curiosity[X(], but I'm tempted. Hopefully, whoever buys it will give us some additional feedback about the engine here;).

RE: Blue head Hanno
 

i assume my hanno is a MKI due to the 3044 serial number?

RE: Blue head Hanno
 

What interesting tidbits can be gleamed from Hanno serial number 3573 other than it being a Mk1?

RE: Blue head Hanno
 

Not a current user,or a history buff; but did use the Hanno (mk1) when "everyone" did,as the F3A power plant.
Certainly in those days,it wasn't necessary to alter the case, or the (red) head, to put Shadel piston/liner sets in.
The Shadel pistons/liners came as ABC, or AAC(which were tighter,and did need slightly more care in running in)-but they both just dropped straight into the existing OS crankcase as far as I remember definitely no machining involved.
The blue head-not so sure about that, but think it possible, that some heads on the (earlier)RFP 61s could have been blue anodisedI think I remember a club colleague at the time had one such OS engine....
The cylinder head bolt pattern was very probably the samejust the Hanno exhaust port was a fancier shape.
An earlier post mentioned a blue tuned pipet-that was an OS (or Hatori made for OS) product,originally made for the RFP 61-I had one, until it was destroyed,along with the car, in an Easter Monday motoring accident.

RE: Blue head Hanno
 

david, we should ask over in the classic forum about serial numbers. there was a thread a yr or so ago dedicated to just this issue.

RE: Blue head Hanno
 

I have a blue OS pipe and it is (same volume and 1st reflector disc placement) a Hatori 601. More suited to the higher revving short strokes than the longer strokes. There may have been another blue one for the long strokes. There was a red, higher volume/longer(650/700?), one for the Hannos.

I had the listing on my watchlist, but it is gone now. I did a search on active and completed auctions, with no luck. Looks like the guy cancelled the auction. Bid was near $200.00 last night, with a couple days left....wonder why he pulled it...

RE: Blue head Hanno
 

that is weird. the engine had serious value no matter what the color the head was. i wonder if there was any funny business going on?

RE: Blue head Hanno
 

The seller had 0 feedback. Inexperienced seller, maybe? Could be he didn't realize that the bidding would probably go nuts in the last few minutes/seconds.....or....could be he got tired of answering questions:eek:

RE: Blue head Hanno
 

Thanks David.

Indeed. I assumed that since this thread was fresh others might have some insight. I also assumed Flywilly, as well as others, might be in the know.
