Anglin's Racer Build and History

[anglin]

I saw an XR with a Dyna Batt installed in the normal battery area; these things are amazingly tiny... The Dyna Batt occupied less than 1/3rd of the space of a typical battery.

See here for info: http://www.performancedistributors.com/batteries.htm

The Odyssey PC680 I installed is exactly the same battery as the Dyna Batt, with the exception of the name, the label, the case color and the price. I paid less than half of the list price in that above web page from a Odyssey vendor. Not sure if you were implying that the PC680 and the Dyna Batt were the same or not. Yep, 13.5 lbs is right (and light).



I assume you were talking more in terms of artistic suggestion, but I wouldn't say less than 1/3 the space. It's a little under half. But it's still ridiculously small.

Good info on the batteries guys - I can deal with $60 a lot easier than $120 for a damn battery! They don't mention if it needs to be positioned upright though - any idea? My open space will be "horizontally liberal yet vertically challenged".

Chris, on the hood, never mind about it dropping on your head, what about a gust of wind blowing it backwards into the windshield?

It probably doesn't have the inertia to break anything. The mounting between the hood and the hood hinges has some give to it (neoprene inserts), so that will help absorb any shock. A wind strong enough to break the hinges with hood could probably do it with a carbon or steel hood.

So who was your vendor for the Odyssey battery? How do I get a hold to them?

I posted too fast, I have more questions. I did not see that the Odyssey comes with marine-style terminals. In order to put one in the stock location using stock cables, would you need this:

What sort of targeted impact forces can the hood take? If you hit it in the center with a bat, what would happen? I would think the forces could be similar.

I purchased my Odyssey PC680 from an outfit called Odyssey World. I thought they used to have a web page. However, I can only find their ebay user ID.

I'd say the best bet is to drop them an email through ebay. I can't find any other contact info.

I haven't checked specs/prices or competing products re these things; my reference to the Dyna Batt was based on having seen it only. Your earlier photos of your Odyssey were of it already mounted so one couldn't see much of the battery itself. I'd certainly compare prices for these suckers from every offeror before buying since these two seem nearly identical externally.

Re the size comparison---in your side-by-side photo it does appear closer to about 1/2 (Nitpicker ) but in the installation I described the area occupied by the Dyna Batt was closer to 1/3rd. That installation again was flush up against the firewall without a battery tray. From the outside edge of that Dyna Batt's mounting plate to the plane where the aluminum heat deflector typically sits [it was removed] was, in my eyes, easily ~ 2/3rds empty space. I surmise that with the Dyna Batt touching the firewall and with that 2/3rds area now physically opened there might be somewhat more air flow while underway which doesn't flow over, but in front of, that Dyna Batt to keep the battery from that heat, and the increased distance of the battery from the turbo might reduce the effct of turbo heat on it after engine shut down. Yeah, speculation; but intriguing nonetheless.

Check the Dyna Batt link I posted; they have three versions with different terminals.

Check the Dyna Batt link I posted; they have three versions with different terminals.

Just for the sake of clarity, there is only one method of connection to the battery - M6 threaded holes. Those different versions are simply adapters, which can be purchased separately, connected to those threaded holes. You can get any "version" and change the adapters as you see fit.

[AnHonestCitizen]

And these are those adaptors, right?

[anglin]

Looks like it. The page specifies that it fits the PC680. Neat design too, with the threaded top portion that allows a standard size side terminal bolt to attach. I used no adapters in mine, since there's no reason when doing all the custom work.

Chris, bear in mind that that prop rod will come loose at the slightest puff of wind-- it wouldn't thump you like the stock hood would, but then again, you might suddenly find your face pushed into the alternator if you were leaning over it and it took you by surprise.

I've thought about the hood coming off the rod. It will certainly happen, however, it will hardly cause any sort of effect on me or my head if that happens. You'd be amazed at how lightly it closes when dropped from full height. Makes a nice, light "thuck" when it is dropped closed. Remember it weighs 6.5 lbs, it's hinged, and it has an approximate surface area of 2100 square inches.

I just ran some tests. If I really put my head down low it packs a decent punch, but at normal, stare-blankly-at-the-engine height, it doesn't have much force. Yes, that's right. I just went outside and intentionally let the carbon hood fall on my head multiple times. And you thought male-retardation ended when you left your teenage years...

anglin, friggin awesome. how much do those weigh?

That picture has become one of my all-time favorite obnoxious pictures (the carbonschlong picture still ranks #1; you know what they say - once you go 5.7 oz 3k tow 2x2 twill, you never go back). The tube weighs about 0.875 lb. The tube could be lighter if it weren't 0.125" wall, but I purchased what was available.

carbonschlong?

and your pic is broken. oops, you bwoke it.

[anglin]

Well, the carbon hood installation is nearly done. I have a few details to wrap up, like:

- correct fastener selection
- welding of modular hood pin assemblies
- anodizing of modular hood pin assmeblies
- heat shielding for the hood
- final fitment of the hood

But that's just about it (until I go outside and see the hood and remember, "oh yeah, I still have to do this, this and this"). Anyway, while we are waiting for those final tasks to get done, here are the pictures of the recent work.

Final version of modular hood pin (for sides of core support; the center is a different design):






All hood pin assemblies installed in the core support:


Center hood pin assembly, with it's slightly different design:


Mounting bracket of center assembly:


Due to the design of the core support, the center hood pin had to be threaded, making it an extra challenge:


All hood pins installed with the hood fitted to the pins:


Aluminum scuff plates early in their production. Just as a note, it's incredibly difficult to cut two concentric circles by hand. The center holes you see are from a hole saw. They got increased in size to about 0.75".


Scuff plates installed on the hood:


Hood pins trimmed to proper height and hitch pins installed:
