[jerryspet]

Hi I was wondering has anyone replaced the charge cooler pump with an electric charge cooler pump? Also has anyone actually fitted a blow off valve to there esprit?

I've done the andy whittaker modification- excellent and easy if you follow his instucutions (I printed them out and took them into the garage).

Chargecooler always cool to the touch now...

I have a moto concept BOV I elected to rebuild my OEM chargecooler pump because I have a marginal alternator and large stereo power amp.

I have done both. I don't have a photo of the BOV install, But I do for the Charge cooler pump. I used an American-made livewell pump manufactured by "Rule Industries" -- 700GPM. I am certain that you could find them with a search on the web. It works great. Here's my web page. The thumbnail photos are blury. Just click on a photo to enlarge it.

Whoa! I don't think you need an engine if the pump is pushing 700 GPM. 7, maybe?

OK, I found it: www.rule-industries.com/livewell.htm

700 gallons per hour, not per minute. Phew!!!

==========================
I've done quite a bit of research on the cc pumps, but in the meantime rebuilt my stock mechanical one for the experience. But, I will say, that Rule pump is by far the least expensive I've seen!

OOOPPPS! You're right guys. 700 GPH.

I've been running an electric pump that is 4.2 GPM and it is a great improvement over the stock mechinical one. Something to look for when selecting a pump is the amount of head pressure it can supply. The Esprit chargecooler has a significant amount of restriction in it. A high GPM rate with a low head pressure doesn't do much good.
If you install a electric pump you might want to think about removing the old pump and plugging the hole.
