SBM Dual Plane Intake vs Single Plane Intake Dyno Results on a Rowdy 408" Stroker
So I’m thinking with 3:23 gears or less you would go with the dual plane.
A bunch depends on the driver, cars weight, camshaft, etc.
I can see a dual plane usage even with 4.10’s. As the article says, it’s what your doing with the car.
If deeper gears like 3:91 or deeper,the single plane as your tack’d up at low speed already.
Same as above.
I’m also thinking that with a rpm engine that revs like a chainsaw you go with the single plane cause your there so quick. If you have a low rpm grunt engine like a Pontiac or Buick you go with the dual plane. But mostly keep it parked in the garage with the door closed so you don’t lose races.
Even if the engine itself revs up quick, that is also the rest of the car that allows it to. Car weight, converter, gears, tire size, etc…
As the article said and we have been told for decades, this still holds true and will normally show best performance results.
Dual plane on the street, single plane at the track.
But there is always a rule to break and that rule can be bent really well.
It’s all in the combo.
Honestly, if you want to run a single plane, realize that is a race intake. Most people under cam a single plane intake.
