Hey,How DOES The SR Work?
Hey people,
Ok,the SR topics have been beaten to death,but then again,Ive never really read anything as to HOW it Works.Ive just accepted that it just does and had this idea that despite its larger size,the box on top acts like a 2nd intake manifold to pressurize the heck out of the rest of the runner length going down nto the base.
IS that correct?Or somewhat?
Any engineer types want to give a little info on how the SR rethinks the TPI and increases power without simply saying its because the runners are shorter?Does it still have a tuning effect?etc.
:D

Re: Hey,How DOES The SR Work? (Bill's86Coupe)
I found this:
Using a "tuned plenum/runner" combination, SuperRam Small Block provides balanced inlet air charge to all eight combustion chambers. In addition, the SuperRam's resonant pressure wave (producing the "ram effect") is designed to occur at higher RPM. When the OEM TPI manifold is beginning to run out of steam, Accel's SuperRam starts to shine. At 4500 RPM, the stock unit's torque has already started to drop off. Accel's SuperRam produced 19 ft-lbs more than a ported OEM manifold at 4500 RPM. The performance gap then increases. At 5800 RPM, SuperRam generates 61 ft-lbs more than the ported OEM manifold.
Mine SR is still on the bench waiting to be installed ... :D

Re: Hey,How DOES The SR Work? (Coupe89)
basically the runners are shorter and therefore tune at a higher RPM. They also have more cross sectional area so they can pass more volume. It is still a tuned intake tho.
