Interesting spin, 4 power valves, overlapping butterflies big hole like a predator.

It looks like the primary is a conventional butterly, but the secondary looks like it retracts into the body...just like an old GM station wagon, lol

Anyone tested one yet? So far all I see online about them is fancy CGI ads with impressive catch-phrases.

Looks like a slide throttle variable venturi carb with dump tubes. Reminds me of a predator.

It's a laudable engineering exercise, but I'll believe the horsepower/torque increase claims when I see independent back-to-back dyno testing against a properly tuned conventional style carb.

Agreed............although my friend picked up 3 mph and almost .3 in et from my mods on his Proform 850 so how much hp is that? Went from 12.03 @ 109 to 11.75 @ 112 ....

Look again and watch the indentations on the "butterfly" ... the whole thing is a slide.

Variable venturi like GM had worked well when you kept the wrong guys out of them. Silverback is not the only new concept in town lately either.

I thought about the SV-1 and wondered why you couldnt have a smaller round butterfly on the same common shaft as the larger one is that through part throttle only the smaller ( internal ) one would open but as more airflow was needed the larger/outer one would open to reclose/overtake the smaller one as it transitioned to WOT. Kind oflike a progressive only one inside the other.

Another way to do it would be like a camera IRIS or a vertical series of wicket gates ( like they use to throttle a hydroelectric turbine) or some variable vane turbos.

WHat else is out there, besides the SV1?

Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Yeah, slide throttle intake setups are not new, not by a longshot.

One that bolts on a Holley base is, though.

If the car weighed 3350 at
109mph is 338.59hp
112mph is 367.33hp
That's a 28.74hp increase. Nice Job!!!!!

Well if Bobby Elvis looked at them I guess I need to buy one

In all seriousness, it looks like a good design regardless of what parts of it's design are "new" or not. I might pick one up to do some testing on my Demon (street engine, roller cam, stroked 422cid, 4.00" stroke SB, currently running a well sorted 950 Holley and making 530hp). There's a local chassis dyno I can run it on for the before & after test when the Silverback is available.

Don't forget the E3 sparkplugs.

In theory, there is no difference between theory and practice. In practice, there is.

Variable venturi like Ford had ! I worked at Ford dealer in the late 70's and early 80's when they had their variable venturi junk. Hope its much better then that was ? Ron

That`s cool and he kept adding jet and it kept picking up so it`s not fine tuned yet and he`s getting a WB so we can dial it in better............

That's a great job! Keep giving it fuel till it stops mile per houring. You know that already. The WB should help keep things from going the bad way.
Never the less, great job! Keep up the good work
If I can ever get Murphy back up and going, she's been testing my patients for a while now.

Anyways,... I'll probably be talking you ear off about carb stuff
