BLP CARB SHOOTOUT Your input please !

[Dave Braswell]

I thought it was to be for single carburetor configuration, 4 bbls maximum. We can't preclude the SV1 particapation.

[Steve Zicht]

Ok , then were still on the same page Dave. I guess the next step is to help Rick Cole locate a decent motor to serve as a test mule. Anyone with race engine shop connections that would like some good PR ? SZ

I brought it up so no one goes in blind, I do agree if sheer plates are added it makes the challenge more complex and expensive for everyone. And the challenge is about the carb, building one to work best on the engine provided. If the intake is a Dominator pattern only an open adaptor should be allowed, either to fit a 4150 or a larger opening such as needed for a Braswell carb, SV1 or other. Limit the height to maybe 2" and run a 2" open spacer when a standard Dominator is used. That way plenum volume has a minimal effect on the combination.

Another possibility, if it can be done before the PRI show, have a raffle that covers a reasonable amount for the carb and maybe even the dyno engine. That would cover some if not all of the expense to the winner and the engine builder.

[jmarkaudio]

Adding as I go, fresh plugs of the same brand and heat range determined by the engine builder will be needed for each competitor, should be at the competitors expense. They need to read their carbs plug info, not the last 3 or 4...

[Dave Braswell]

Rules, rules, rules. the demise of open competition. You want everybody to run through a restrictor plate ( a 4500 opening). What happened to "run what ya brung"?

[CamKing]

I say go with a cam around 262-268@.050", then you can all do what ever you want with the carbs.
I'm just a lame cam designer, but I think the engine should be a 400-420ci SB or a 460ci BB.
This should be about making the most efficient carb, not about seeing which carb can feed the most air into some over-cammed 600ci engine.

How about a sheet metal intake, with a top opening large enough to accommodate the largest carb. 1/2" thick adaptor to suit.

[Steve Zicht]

I think CAM KING has the right idea as to what I was thinking. Regardless of the size and make, it has to survive up to a hundred or more pulls if alot of people enter the shoot out. SZ

What if one has a bad tune and takes out the test engine early?

[Steve Zicht]

If the carb is poorly tuned, and the dyno indicates too lean, the pull is stopped and that entry is eliminated from the first phase of the contest. However, youll recieve a certain alloted time to compete in the second phase of the contest with ' retuning ' your entry on the dyno IE jets, air correctors, power circuits and so forth.

Were hoping that a contestants carb doesnt come apart and drop pieces inside the intake that would damage the motor. I suggested a safety screen be installed between the carb and the intake to catch parts. I recall that somebody makes these safety screens. SZ

[jmarkaudio]

I would hope the carbs would be live tested prior to arriving, it should eliminate anything being dangerously lean. A preliminary visual inspection and screw check by someone at BLP should eliminate parts falling in as well, a thin 4 hole plate will prevent internal linkage Dominators from being an issue.

[Steve Zicht]

I already mentioned that on page one jmark. I brought up a pre install safety inspection before each carb is mounted on the mule motor. A safety screen will cover 4500 and 4150 applications. SZ

[RayJE Carburetors]

i think we are over complicating things...give the carbs a visual and check for foriegn objects if u like .....fitting a screen under patricks SV1 with a big blade is going to be a pain in the ass .. im with dave... no rules or restrictions ....Mule engine selction will be the key.....IMHO if u use a decent small block or 800 to 900HP Big block then all carb manufacturers and carb builders will have something in there arsenal to be competiive with.

invite Holley to compete as well. They might like to show off their new HP series this way

No way! Talk about a way to change the flow on any carb made, just put a screen under it.

[Procision-Auto]

A competition of this magnitude may warrant a back-up engine with similar specs. Just imagine the alternative! People flying in from all over the country and big name
guests; it would be a shame to send them home early without a chance to show their stuff.
