does any1 actually own one that has real life info ?

I have been searching for days on google ,I have read what is on TC.

but all i have learned is what BG has advertised,these intakes are pricey but cool too,any one have info to share ?? \\ Jeff

 

[novaderrik]

they are a lot of money to spend for something that doesn't flow as much air as a good single carburetor setup.

 

[jthomp1256]

from what they say the numbers are close thats why i want some good hands on tc members somebody has this stuff

These have been out for a while, right? Over a year?

I have yet to see on on a car, at all... I haven't seen one at the larger shows, and while I don't get too many magazines, i still look trough alot at the store...

Yes, pricey... Nice looking, but I wonder if that high price is limiting sales?

 

[novaderrik]

it is the kind of thing that street rodders and show car people get all gaga over.

 

[cobaltchev67]

My guess is that you'll probably never see that setup at a drag strip, or any other race track being used for that matter. While cool, novaderrik is right....street rodders with money to burn and not necessarily high performance intentions.

You are correct. There's not a lot of info available on that set-up...anywhere.

There is a fellow who is a member who works for Barry Grant. Maybe he will chime in and get you some answers. Or maybe you want to PM, email, or call him. His screen name is "Tech @ BG".

I chose to do a 67 vette tri-power because I wanted something different and something that would give me considerably similar performance to a single 4 bbl set-up.

Yes, I am pretty sure I could squeek out a few more HP over 6,000 RPM with a modern 4bbl set up, but I am more interested in what is delivered from idle to 4000 RPM (which is where my motor will spend 98% of it's time).

Did you read the following post? Lots of good info in there.

http://www.chevelles.com/forums/showthread.php?t=254552&highlight=tri-power

Why that over the BG? Primarily because of total CFM. The BG set-up is too small for a 511 BBC. It flows 750 CFM. The vette tri-power flows 1050 CFM (adjusted CFM flow rate for 2 bbl's is about 930 CFM for that set-up).

That should be your primary decision maker, "Is it well matched to your motor CFM?"

Second decision is what is more important to you?

Do you want something different?
Driveability?
Street or strip?

Hope all that helps. In the end it's your car. You should do what you want with it.

 

[jthomp1256]

yeah i am building a 489 ,,they meaning BG says the 750 flows like a 850,,but no where and i mean no where is there info on that setup ina real persons hands,, BG TECH where are you ..

i have read that tri power blog lotsa good info there but the corvette 1050 ones are really hard to come by ( unless u know something i dont )

a couple of years ago when the small block version came out there was a magazine article where they dyno tested the 6 shooter against a single carb. the 6 shooter was way down on power and torque compared to the single carb, and cost about 5X as much.
the general gist of the article was that the 6 shooter was a retro bling addition to a high dollar car.
3 deuces was the thing to do 45 years ago when 4 barrel carbs were hard to find and 2 barrels were cluttering the junkyards, but these days they just don't do anything more than look cool and add extra expense and complexity.

Then I guess the article and tests with a tri-power on a BBC that peed all over a single 4 bbl is invalid?

 

[rianbechtold]

I think they are ugly compared to the original 3x2 set ups.

 

[Chicken Coupe]

I couldn't agree more!

which article is that? i've never seen a big block test, just the small block one i mentioned.

I like the BG Six Shooter setup...almost bought one for my '67 big block for the unique bling factor. Actually watched Ebay for a while looking for one used during the engine build. Just can't get past that price on a new one...about $1k higher than it should be, IMO.
Ended up buying an RPM Airgap oval and a Holley 750HP.
But, if I do find a Shooter setup, I'd swap.

 

[jthomp1256]

Will they even fit under the hood of a 67,i think BG told me they were 12.5 from block rail to top of air filter i measured mine with a stock performer and have 10.5 at best,,,

Novaderrick 1 of the test's i pulled up the small block made more hp and torque with the 3 deuce ,but cant remember what intake they used for the single 4 ,,I have seen no comparisons with the big block yet except ,on the camaro site and a guy with a 402 did a dyno test and come up with 2 hp difference Jeff

the small block test i remember compared the Six Shooter to a 750 Demon on an RPM Air gap. i'm going off memory from a couple of years ago, but i'm sure it was a 750, because that was the same cfm as the 3 deuces, and it was an air gap because everything uses an air gap these days.

The BG 6 Shooter is an impressive looking induction system but as mentioned a Single 4 will produce more power due to improved Modern after market 4 BBL Intake Designs. I ran a 327 6 PAC back on the 60's which easily hit 7000+ rpm but you have to consider that the after market 4 BBL Intakes were in Beta back then and relatively rare. We usually played around with Stock 3 Duce Intakes or Offy's.

I think Bill's got the Tri-Power "jones".

This ought to get him all "bubbly". l

which article is that? i've never seen a big block test, just the small block one i mentioned.

It was in an issue of Corvette Enthusiast. It was one of the things that gave my tri-power dreams the green light. The other was finding a 67 manifold w 3 NOS NIB Holly's for $1700 shipped.

I was able to get a copy of the back issue. I called and spoke with the engine builder/ dyno guy and the person who did the carb restorations and modifications.

here's an overview from the Corvette Forum:

Last May, Corvette Enthusiast did an 11.5:1 489 buildup using AFR 315 CNC heads. They tested 3 induction systems: Holley Strip Dominator 4150; Edelbrock RPM Air Gap and a modified 67 Tripower. The 4-bbl intakes were tested with a Holley 950 HP carburetor. The results were impressive:

RPM Air Gap w/Holley HP 950: 643 HP @ 6400; 594 lb-ft @ 5100
Vic Jr. w/ Holley HP 950: 641 HP @ 6400; 603 lb-ft @ 5100
Tripower: 655 HP @ 6200; 591 lb-ft @ 5100

Several years back I ran a Tripower on a mild 540 and made 655 HP at the flywheel. The heads and manifold were ported by Bernard Mondello.

I like the look of the Tripower, and with proper tweaking, can be made to run very well. As you know, the 68-69 Tripowers are lower than the 67 unit, and will give up a few HP accordingly. Given the silly price Tripowers command these days, you’ll want to think long and hard before putting one under the knife!
