CARBURETOR SHOOT OUT 2012

[500PS]

I might be misunderstanding, I don't Think Braswell would enter a carb that wasn't His. If he did run somebody else's. Would they let the score stand? I am confused as to why Mr. Braswell run an SV-1. Somebody help me here please.

there have been countless cylinder head shoot outs, camshaft shoot outs, intake manifold shoot outs, header shoot outs, mufflers etc etc etc.

we make our buying decisions on the details given in those contests. maybe we would base our decision on who made the best avg tq? or maybe the best avg hp? or who made the most tq at the hit? or who's carb used the least fuel? maybe on which one had the best distribution on the bb which had 8 O2's

you gave us the first and second which only hurt the others since we have zero info on them. these carb builders should not be ashamed of how they finished. we are the ones who buy these carbs, without "us" there would no "them", its not the other way around.

This is fine, but... If I was in the market for a carb & knowing it was all very close as has been mentioned several times.. I would ring the shops i wanted to do business with & choose whomever i felt most comfortable with. It's not really that difficult, is it?

From my understanding, the competitors wanted to see how they stacked up against the SV1. The SV1 carbs were ordered for the respective engines in the shootout (I believe they were independently ordered for both engines with the specs provided to all competitors) & put on the pump with Mr. Braswell looking after the tuning aspect for them. If my understanding of the situation is incorrect, I'm sure someone will be along to clear it up.

ya ya ya,, dont worry about it right, they were all within a wisker of each other in performance..so just call one up right. sorry, but i need to base my decisions on facts&figures. what dont you understand about me and many others wanting to go through all the numbers&details to figure out a few things on our own,,,or are we just to god dang dumb for that?

"we better not give them clowns all the info, they'll go out and hurt someone" is this what you think? i prefer to think of myself as an educated consumer.

we heard this dyno has all the bells and whistles, so lets see it!

you see..your guessing too because "THE INFO WAS NOT GIVEN"

Where did I call you or anyone else dumb? Fair dinkum you yanks are strange sometimes... If you can pick the difference in carbs that they had to take out to several decimal points to find a winner, you are a much better man than me...

You are wrong mate. The information is written in black & white on the threads here & on the bullet. Feel free to peruse the threads on both forums & get back to me.

[Milan..]

Its easy , buy the CHEAPEST carb in the "shoot out" .... and your good to go ....

Sigh... More cheap shots... How about buying a carb off one of the companies who had the balls to attend? Leaves your chosen vendor out my friend...

Well said, and maybe it just makes too much sense for some who rather stir up controversy on a forum than pick up a telephone and actually get the information they claim they are after. Maybe that is just too difficult and want spoon fed the information or for someone to make the decision for them. Now I know I'm going overboard in this with most of you and understand you would like to see more numbers, but just let it go as for this year's contest as it just isn't going to be all laid out for you due to the agreement that was made with the contestants. If you have enough interest spend some of the time on the telephone instead of complaining about it on the forums and you will not only likely get the information you are after but you will develop relationships with those businesses which should in the end help you to make the best decision for you as the difference in performance shown at this year's shootouts was not much - within 1.3% in average acceleration rate for the top eight placements in the SB shootout. Some of the contestants are already posting their results here and on the Yellow Bullet forum, so a lot of the information will be made available via that route as well. Your combination is likely going to be different than those used in the shootouts, so it is going to take some tuning to perfect any carb for your application. If you are looking to do no tuning at all, then you may want to talk to the out-of-the-box winners first and then go from there in your decision process.

All of the competitors that were there seemed to really enjoy the event and worked together to perform the best possible - especially as mentioned in the big block shootout. From this event, I'm sure most everyone there learned something or benefited in some way that will in the end benefit us the end consumer. Everyone, therefore, should be glad that this event happened and be looking forward to the improvements/advancements it could make and with each year that it held I'm sure it will get better and better and even more will benefit from it.

So how did the SV-1 Carb do??? Looks like a super cool carb and seems to work for the few people I know who have run it. Would be interesting to see the numbers.

But I think the real quality of a carb is how it responds (coming off of corners or coming out of the hole), not total HP. Not sure how you can test that unless you put it on a circle track car or drag car and timed it. Maybe they can make that the "Carb Shoot Out 2012 Part 2".

From my understanding, the Revolution dyno used at BLP is capable of simulating a race running laps at a programmed track. I think they have used one in North Carolina to simulate an entire 500 mile race, but might have heard that incorrectly. The following was a post made by Mike Laws at BLP regarding the possible use of a transmission in conjunction with the dyno for next year's shootout.

If I understand the capability of this dyno correctly, It can closely replicate the loads the an engine sees in a race car to include a shift. Is this correct and if so, will there be a shift replicated in the course of the pull so that shift recovery will come into play? I think if this is possible, it would be an even better representation of how these carbs would perform on the track.


Mark is correct. The dyno will be able to replicate a shift as soon as we are able to retrofit a transmission to it. There will be no transmission installed for the shootout. Shift recovery is definitely on our radar. There is a clone to this machine in NC that is making a 4-5 shift and accelerating to more than 10,500rpm with success. There should be a transmission installed on our dyno for next year's shootout.

The 2-step feature on our dyno is valuable and will probably be used on the b/b engine at the shootout. It's weird to watch (& hear) an engine on the 2-step, then released while on a dyno. Effective; but weird.

Edit: I found another post from Mike Laws describing additional functions of the Revolution dyno:

The Revolution engine-inertia dyno used for the shootout has been successfully used for a hands-off, non-stop 500 mile simulation run to 9400 rpm and would handle a Bonneville LSR sim. It allows the engine to 'accelerate the mass' just as an engine in a race car does. It does not use a 'simulated' mass for acceleration testing. It uses elapsed time to measure performance just as happens in the majority of racing, but also has a load cell & water brake for steady state and 'variable state' load testing if necessary. It can also decelerate a mass and measure the e.t. It can do all of this using 1% throttle opening to 100% throttle opening that can be variable. It has a gearbox and variable inertia wheels.

The boosters are BLP 5105 16 hole boosters with the fuel channel on the OD widened on a lathe to allow more fuel. Banjos were stock with the exit hole rounded. Metering blocks were BLP, they were 4 emulsion hole blocks a prior customer no longer used. Metering came fixed, all passages were drilled and threaded for removable bleeds and idle jets. The angle channel passage was opened to .155, booster pins at .160. The bleeds used are from top to bottom: kill in the angle channel .028, .018, blank, .022, .024. Looking at the AFR's I might have gained a tad more plugging the bottom e-bleed. Idle jet is .037 and is threaded where it gets fuel from the mainwell at the bottom not the top, IAB .067, no power valves. Main air bleed was originally .031, the change I made to pick up power was going to .026. Jets were .127, but remember the oxygenated fuel we used needs more jet. Standard racing gas would be roughly .010-.015 lower. T-slot jets are .063, .128 N&S with standard nitrophyl floats, notched in back with long BLP jets.

Is this the carb for the small block? Did you have that set up as a 2 or 3 circut?

No intermediate metering listed... Yes it is a 2 circuit carb. The blocks are 4150 blocks with the mainwell exit channels enlarged. The same can be done with the standard BLP blocks, the ones I used I bought several sets at a little cheaper price as they were leftover from a company that no longer used them. All of the original metering that was fixed was drilled out and threaded for removable bleeds and idle jets.

The SV1 did not make the top 8 in the small block class but did in the big block class. The contest winner(s) were the fastest accelerating carbs...

The shootout was an open competition - meaning any carburetor may be entered by anyone. Several teams entered Holley's, QFT's and Braswell's. There were also a few billet pieces. Weber's, Edelbrocks, Predators, Quadrajets, etc. would have also been eligible.
