Who's going to be the first to try one of these on a rotary?

 

Very nice.
I hope it totally eliminate the problem with the fuel bowl being turned sideways causing problems.
Leave it up to Barry Grant to re-invent the 4bbl carb.
Looks promissing.

 

Looks too long to be used on a rotary. Unless they offer a 2bbl version.

 

I've seen dual Weber DCOE's on a rotary so it should fit.

 

it should fit, but I don't see any type of advantage on of a inline arrangement on a rotary over a standard 4 barrell, all other things being equal of corse.

 

Better fuel bowl design just to name one.
Should do a much better job controlling fuel level especially when high G-forces are involved. Only major down fall to the traditional 4bbl design would be the lack of stage secondaries on a rotary applications.

 

I have a Intake system I just completed for my P-Port motor that looks very similar to that setup. The system consists of 2 Geers Engineering 62mm Carbs joined together to make one huge inline 4 barrel carb. Complete custom setup for my Drag car. Hope to have it running in a couple of weeks.

 

Twin 62mm G's
Should be interesting.

 

+ 1 on the cornering issue.

An inline design would make it easier to have equal length intake runners. The problem with this BG carb is that the primaries are the 1st and 3rd barrels not the two inner or two outers. The intake manifold might be a little tricky to make.

 

Fellas,
Not meaning to thread hijack. Quick question here about possible manifold design. I understand that the manifold will be a bit convoluted due to the the 1st and 3rd "barrel" of the carb being the primary ones, but don't you want a fairly long intake runner on most rotaries to allow the air and fuel to mix properly anyway? I always thought that if the intake runners were too short it caused problems with the intake charge?
Curios,

The air and fuel are mixed at the venturi. Everything after that serves to un-mix.

That said, I am reminded of the Autolite carbs that Ford made for the Boss 302, back in 1969... manifolds available were single carb, and independent runner with two carbs. They had a jet arrangement similar to a Weber where you didn't have to disassemble the thing to change jets.

Everything old is new again!

 

That's where It seems the design came from.

 

Kinda cool little piece of kit. Not sure how useful it'd be for rotaries (that seems like a lot of potential flow) but what the heck. And no reason you can't fiddle around with the linkages that work the secondaries to get them to open differently.
