Just what is it with the JE pump that pisses you off Glenn? It is no less, or more, efficient than any other Berk pump out there. Is automatically set back, like everyone modifies their JG's to do, has a built in ride plate. Yes, they can benefit greatly with a shoe, and other mods depending on the hull, but we're talking 70 ish numbers here. I think Ralphs boat would probably STILL pull off 80+ MPH with a JE pump, maybe more moving the motor back a tad.
Fair question...Those that know me know that I will never make a statement without being able to back it up, or at least try to back it up.
First off, I never insinuated that it pissed me off....But it
is the least efficient Berkeley pump design out there.. Hands down.
The suction piece (hull insert and transition) is the flaw in the whole design, the inlet is steep and short and when speed becomes the desire, this would be the first thing I would change. If you were to hold a round keel or a delta pad Berkeley intake next to an E set up, the differences would hit you like a lightning bolt. The entrance path is completely different and much more abrupt making proper loading at speed possible, but extremely difficult. They do have a descent holeshot though.
I know of very few 80+ MPH boats with a JE. Very few.
My point being, there's NOTHING WRONG with the JE pump. It just does not work like the traditional Berks, nor does it necessarily respond to, or even accept, the typical "hot rod" mods normallly done on those. It is already "set-back" eliminating a ton of work there, it sits much lower in the hull, thereby lowering COG (Can't do that on a JG) AND eliminating the need for "Droop Snoots, etc to get the thrust angle deeper in the water.
The thrust angle is more of a hindrance than a benefit in most cases, I compare it to a very "sloppy" set back. None of the geometry is what I would call desirable. Water does not like to change direction abruptly, something the JE would like to do twice when compared to the JC/JG config.
It's intake is a little on the smallish side, not much. But if you compare the intake size of a JE to the SUCTION HOUSING inlet size of a JG, they're damn near the same, and the JE has this dimension right in the water. No intake required, No need for inducers...... 
Longer=more efficient, more efficient many times = faster, better handling and safer.
IMHO, the JE can perform and hang with any JG given the same mods, tests an treatments. Both can and will benefit from loaders and shoes, but boats with the JE need to be handled a little differently. Most of the mods done to boats to move COG to the rear has already been done, etc, etc, etc. I don't get why it's so hated and compared to a Panther???
Panther pumps are a totally different animal. Don't confuse the two together. The JE pump has its purpose, a heavy cruiser that can benefit from more cockpit space due to the setback of the engine, top speed gains were not one of those...IMHO
So I have to respectfully disagree.
From the suction housing back, your JE pump is the same exact animal as every other Berk out there.

Similar yes. Same no. You could not simply remove all the nozzle, steering and reverse gate and simply swap them over to a JC. There is a bit more to it than that. The bowls are identical, I agree.
Not trying to discourage anything to the OP, just trying to for warn him that he may be in for one hell of a frustrating journey.
And Ray, no disrespect brother, just defending my comments.....There is a reason you don't see JE's on the circle boat circuit.
