riva sc boost
i am more intrested what the boost is on this new riva sc assembly. also i know for a fact that a stock head has problems running at 8400 rpms(valve floating) i hope they are right about that or we will see alot of rebuilts in the near future.

Put .030 shims under your valve springs it will help.

rxpdoo, I hope not since I am in my 3rd year of running 8400 rpms on a stock head. About 130+ hours on it also.

Lets not concern ourselves with impressive boost numbers.
Its volume of air that is more important.
Also, 8400 RPMs is proven safe for the stock valvetrain.

"Boost" is just a measure of backpressure (of course that's usually indicative of a greater volume of air being moved)...
If a different supercharger impeller can move more air (or even the same amount) but make the compression of it "smoother" (so to speak) it will be a drastic improvement because:
-The less chopped up and turbulent the air gets the better it will mix
-the smoother the flow the less heat will be created
You see where I'm going with this...It's not just about moving more air but also about improving efficiency.

The new Riva sc impeller looks identical to their old Vortech sc impeller, but it has taller blades. Hence the reason for the modified front housing.
The taller the blades the more volume of air it moves.

Chris: I have been told that the riva wheel is more efficient, what would be the best way to explain how I will feel the dif, is it accelleration?, top end? Both?...PR...
