demon 98's.....and the new rod and custom

The first setup is the Six Shooter its an intake and carb kit. The second is the 98s we are talking about in this thread. Two different beasts.

 

Thanks Thirdyfive. I'm still confused, because the carbs in the first pic look smaller, (and more traditional). I guess that makes sense, to fit on an old style 3-carb manifold the fuel bowls had to be changed and everything moved closer together. So to be clear, this one is the six-shooter?

 

to the tech at BG: for a 235 - 6 cylinder application for dual carbs, would it have to be progressive linkage or could you work it with 2 primary carbs and open them at the same time?

 

Yup.

Here is a link from the BG/Demon site about the six shooter.

You'd get better drivability with using a primary, and secondary and progressive linkage.

 

Some smaller float bowls, with a smaller, less con****uous DEMON logo might get them put on some more cars.

If these don't sell well, We will be searching swap meets for them in 25 years.

 

Hey BG . . . I think you've done a great job and it is nice to see somebody making some cool carbs for the older 3-bolt crowd. I have at least a dozen 97's, 6 or more Stromberg 81's, etc --- BUT, I'd love to have 6 of these dudes on my blown Hemi - with a progressive linkage that brings the center two in, then the other four progressively.

Idea: If BG wants to do a real dyno test on a blown 392 Hemi - let me know. I'm getting readty to start/tune a new high-output motor (couple weeks away) and it is currently setup to run with two BG Mighty Demon 650's. I also have a six-deuce blower manifold (thanks to Savage), that would be fun to configure with six of your new carbs -- and see what the dyno says. Maybe test a progressive setup versus six all together, etc..

Now that would be a great bit of research and data collecting in my mind! Hell, I'd even be willing to setup six 97's and run that as a test as well . . . would be a great article, great pictures (who doesn't like a blown early Hemi) -- you might even sell more carbs! No - I don't have a dyno, but we can figure that out -- maybe Ray Barton. And then, you could make me a sweet deal on the six 98's and everybody wins . . . yeah, thats the ticket.


Whew . . . better go have a beer before I p*** out from all this Imagineering . . .

so let me get this right..if you want to run 6 of these 98's...the center 2 are going to be primaries with chokes and the rest will be the secondaries??? is it better to run it as a progressive linkage set up instead of all on or all off??

 

at 215 cfm a carb.
does you egine need 1290 cfm at all times ?

it's better to use the progressive linkage..insted of agressive

 

I wonder about the one primary and one secondary on a twin setup for a flathead. I have always seen twins running non-progressive on flattys rather than progressive. It seems like the secondary without an idle circuit would really lean out the cylinders it feeds, especially on manifolds where the carbs are spaced widely apart.

 

They're no stromberg 97, but I don't think they look bad. I'm just happy to see that someone has taken the initiative to build a totally new 3 bolt 2 barrel carb. You've got to admit it's impressive, seeing as how they haven't been used in production cars in a good 50 years. They'll probably work real nice.

The regret '32 sedan was way cooler in the old pic with fenders and hubcaps!!!

 

OK Skratch 1290 at the stop light probably wouldnt be a good thing just idling...but i am sure curious to see how they sound wide open...cant wait till they come out..

 

Well, since you asked, I have to agree on doing somthing about the float bowl. At a minimum take the name off of it please, but a little more retro styling would be even better. When I buy somthing, it's bad enough shelling out that kind of money for somthing. I don't wanna freakin' advertise for the guy too.

A carb's CFM rating is it's theoretical maximum flow. It will only flow what an engine will draw through it. So you can put a dominator on a 50cc mini-bike & it's not going to flow 1100CFM.

If you have significantly too large of a carb, throttle response & low-speed qualities will suffer because the signal to the venturi will be weak.

Watched some dyno pulls with a stock 59A flathead & 3x2 w/straight linkage pull just fine. That said, driving on the street & dyno pulls aren't the same thing & I'd be inclined to run progressive linkage on just about any 3x2 on the street...

 

Interesting idea! We'll toss it by the marketing people. The main thing would be to actually get the magazine interested before making any type of commitment.

 

Running progressive linkage will give you better drivability than trying to open all of the barrells at once.

 

On a two carburetor intake like that you could use one primary carburetor & one secondary or two primaries. Running two primary carburetors would allow you to tune the idle a little more specifically with a more radical camshaft. Once you're off idle they would both run the same.

 

Thanks for the feedback. At this time it won'y be cost effective for us to cast new float bowls for these until we know how they are going to sell. From there we can see what we can do.

 

Progressive 2-Pot? I would not be running a progressive linkage on a 2-pot setup -- don't see the need. On a street engine with a 3-pot, probably.

Some 2-pot manifolds have the carbs spaced way apart (typical "race" versus street versions). On the ones with the carbs way apart, I believe like you that the cylinders far away from the carb with idle jets would tend to be lean. With just two carbs, I see no big deal in running dual idle circuits -- especially in a larger motor, hot cam, headers, etc.. I'd have my two carbs setup exactly the same (IMHO).

 

Maybe I'll contact a few of the mags . . . see if anybody is interested and get back with you. As the motor has not been fired, now would be the time to set something up . . . would be some fun in my mind!

 

When they come out i know i'm going to be in for 6 of them....see what they do to the small block i'm building for the 38...i know it will look good in the visual department

 

I want em as soon as they're ready. Ill run em on my 39 chevy truck with a 56 322 nailhead

 

We're going to have some on display on a Y-Block up at Woodward if you're around.

 

Yeah, aeronautical like in flying saucer. . .

 

Who cares, they are a modern version of an old carburetor. So they look a little different...Three of these look a hell of a lot better than a 4bbl. Hell they even look better than the Rochester 2GC's in my opinion. And since the majority of you ***holes are hording all the 97's and 94's...this leaves many of us looking in BG's direction.


I just got off the phone with BG about some other stuff, and I asked about the 98's. They said look for them in October '07 at a price of around $395 a pop.

 

Well said about the appearance of these. I think these look great and would fit right in on a traditionally styled rod or custom. Care and feeding going forward would be a lot simpler too.

At 400 bucks though, I must say that I'm very disappointed about the price. For the same exact money, you can buy brand new (& improved) repo Stromberg 97s.

To be competative, Honda or Suzuki doesn't price their cl***icly styled V-twin bikes anywhere near what a Harley goes for, even though one could argue the rice burner V-twins are better (more advanced) bikes.

In my opinion, BG should take a que from this and price their 98s more competatively. At say $250 each a dual set up would set you back $500 and a triple set up would be $750 as opposed to $800, and $1,200 respectively (as they're priced above).

Come on BG, give us a financial reason to buy your product!

Maybe we need William Shatner to act as the HAMBline price negotiator.

 

Thank you for your feedback. We do not price based on a market, but based on production costs. We're not trying to be the end all be all, just an added option that guys can choose as an alternative.

 

I'm in the retail business so I'm all too aware that if you don't price to be competative in the market, you won't sell many. This philosophy worked pretty good for Henry Ford, but I'm sure you guys know better.

Good luck.

 

If you want to be an alternative...drop the price so that us broke guys can have something other than the typical 4bbl.

I'd love to have the 98's...they're different, they're new, and on my setup, you wouldn't even see them, so the nose-up traditionalists can't *****. But at that price...I'll stick with rebuilding some Holley 94's, Stromberg 97's, or even run a 4bbl. and save my money for visits to the gas pump.

 

Are you listening BG?
