Thanks everyone!
I bought this one:
The interesting part was that there were several old pump vein parts (even after repeatedly flushing both ways) inside. The blades were blocking most of the water ports. If you look close you can see the indentations that formed over time by the pressure of the water on the rubber bits. It might be worth testing your cooler to see if it flows acceptably.
That's my old impeller on top with the hub next to it. The hub was detached but otherwise looked pretty normal when it was in the pump (except that it spun freely).
This morning was a nice cool day in Florida and I took my car for a ride across the Sunshine Skyway at 8AM. The car ran fantastic and the power of the engine was clearly up compared to a typical hot Summer Day.
Of course I didn't break any laws, but it sure seemed that I made the 5 miles across the bridge in a lot less than 5 minutes.:no:
I have made the point before that the chargecooler system on the SE through S4S is often neglected, and probably does not work as efficiently as designed.
This clearly was a problem for you and you were basically driving a non-chargecooled car.
Remember that the chargecooled SE produces 40hp more than the regular Turbo, and a lot of those horsepower are due to a functioning chargecooler.
I also am a strong advocate for maximizing your chargecooler with regular maintenance, proper heat shealding, and proper coolant. And beyond that increased capacity with electric pumps and and larger chargecoolers. We have seen some SLOW cars with non-functioning intercoolers.
