The e-pump has a life expectancy of 3000+ hours, which is a ton. Consider 40mph*3000 hours, your e-pump should be good for 120,000 miles, assuming you average 40mph the whole time. Assume 25mph*3000hrs = 75,000miles. I'll take that. The older e-pumps had less time alotted for quality, but the new ones are better. As for the factory one, they last about the same these days.
As for the rpms, I was running under 750rpms for sure before the pump, and it is now running at 750rpms at idle. Once in drive, the idling rpms go up to almost 1k.

RE: Underdrive pullies
Anyone using underdrive pullies in Arizona? What results are they having? I was looking at the package from RPM for approx. $1,000 with intake, pullies and programmer, it seems like the best hp for the money but I don't want to have problems with A/C or alternator. I won't be doing any other mods or stereo if I do the RPM kit.
