Hi, Guest
I spoke with the guys at http://www.escortfocus.com about their 50% UDP and my reservations about running it and having cooling be a serious factor. Here's what they said:
Have you ever had negative feedback or noticed negative effects on the cooling system of the SPI after installing the 50% UDP?
No, the pulley doesn't run the water pump or fan. That runs off the timing belt. The UDP controlls the A/C compresor, power steering pump, alternator, and air pump if it has one.
What is the known potential for the SPI to overheat while running the 50% UDP?
Again, has no effect on heating. If anything, the engine may run slightly cooler due to less load on the engine.
Alternatively, are either of the above concerns applicable to the 25% UDP you also sell?
Does not apply. You will get better economy and performance from the 50% UDP.
I don't know about the Zetec, but apparently the SPI's water pump isn't driven by the main serpentine belt... which makes the cam belt-driven anyways because it's driving the water pump? :huh:
I'm going to try to have the UDP installed before the dyno day. :)
I'd say go for it Jay... how can you really have any detrimental effects from it?
