I bet the RPM will make the same bottom end and top end as the Stealth. Some single plane intakes will make the same bottom end as an RPM. A lot has to do with your engine combo. The 1,500 to 6,500 is just a loose guidline.killerformula said:power band on the stealth starts at idle, the performer RPM doesn't advertise power until 1500 RPM and later-
Don't forget 1Bad, that the intake velocity has a lot to do with the operating range of the intake. A 400 SBC will have a lot higher intake velocity than a 283. The powerband will start lower with the 400.1BAD80 said:The manufactures claim are estimates at best. FALSE !
All the math modeling and flow test are done at all the manufactures, more than one way at that.
I guess they should throw away the flow test machines then. Their tested the same way as a head for flow.
I wish I could guess that close.
I made flow tester's for the oval one on the V8 back in the 80s and could measure the size of a BB difference between ports.
Even Flow must be controlled for all the cylinder's, this is the job of the intake. :drunk:
I'd just say man, that 1bad knows what he's talking about... he's built these motors professionally and worked on NHRA dragsters....lluciano77 said:Don't forget 1Bad, that the intake velocity has a lot to do with the operating range of the intake.

Another item to address is the stall and gearing. With a performance converter you only need enough bottom end torque to get you into the beginning of your powerband. With lower gears, the engine isn't under as much load, this will affect the bottom end feel of the car.
