[QUOTE="bomrrman84, post: 14459224, member: 137535"] This discussion is slightly different than the one usually addressed. It's been a while since I posted on here, and I would like to address a cooling issue we all struggle with. We all know the stock IC pump sucks and is prone to wear out. I've gone through 3 since owning my car and one with my lightning. the jabsco or meziere pumps seem like a valid option but, centrifugal pump are prone to break if run for extensive periods and are not meant to be run ALL the time like the applications we have here. my question is this: has anyone tried switching to a 12v diaphragm pump? Centri pumps run high flow, low pressure. Diaphragm pumps run low flow, high pressure. that being said they also seem to be much more reliable, that's why farmers use them for sprayers and such. they do have more parts but that only seems to be an issue on the larger industrial type pump used in factories. the only 2 downsides i could see to using a diaphragm pump would be: 1. Noise: Diaphragm pumps are noisy and need a rubber mounting bracket. not even something most people installing one would care about since the noise from exhaust, fuel pumps, blower ect. are already loud. function over form, we are talking 1/4 mile applications here. long story short, I could live with the noise. 2. Pressure: This one is a little more serious. could the intercooling system handle the pressure delivered from this type of pump, even though it is low volume? IE: get bigger lines, and the pressure goes down. The pump may not even flow enough to be efficient on our applications so some testing would have to be done. the biggest thing I would worry about would be the intercooler possibly bursting but, those are rated to much higher pressures than suggested here. possibly blowing off lines but, if you do it right the first time, there should be no drama.
