Is anyone here using an aftermarket intercooler pump.

 

Some guys are using Marine Application Bilge Pumps

what does the stocker do GPM?

 

Good question

 

If the fluid is moving TOO fast it will not have time to properly transfer heat

 

I believe the Ford (Bosch) pump puts out between 3 and 4 GPM @ .3 Bar pressure. I'm actually doing some research on a higher quality aftermarket pump as we speak with similar specs. I'll post my findings in a few days.

 

Also, you shouldn't pump the coolant too fast or too slow, due to the thermal absorption efficiency. So volume IS critical.Hard to beat the stock one for the money,though.

 

Cool
I would be interested since my pump has a lot of miles, and is close to 6 years old

 

The spec fluid transfer rates may be a compromise between the optimum dwell time for the core and the optimum dwell time for the HE (and perhaps the output of economically available pumps). Add an aftermarket HE or higher-than-stock IAT2's into the mix, and maybe the whole equation changes.

AFAIK, no one has ever measured the effects of different flow rates -- we all just assume that the OEM pump provides the optimal flow. Someone should just try another pump and see what happens to IAT2s and recovery times. Who knows -- maybe this is the next great mod?

 

Check this out, I thought it was pretty interesting. http://www.benzworld.org/forums/r170...placement.html Todd

I also was interested in this and was checking around other than the one shown above in the link above the majority that I tracked down were factory type replacements with similar flow rates to what were currently running.

Mondo, please post your findings as my quick search netted very little on the high end.

 

LFP advertised a replacement pump recently!

Exactly what I was talking about to a tech at one of the Jabsco aftermarket pumps.Johnson also makes a great pump as well. He did mentioned that piping diameter was more important than the piping length (on average) as far as pressur is concerned.Volume should be similar being that it is measured at the outlet of the pump. Assuming that dwell time on a larger H/E is the same with a smaller H/E(time fluid enters vs fluid leaving) the only thing that changes is the volume of fluid exposed to the air while in the H/E. That would lead me to believe that a similar pump should do fine. He is getting back to me tommorrow, so I'll post what he thinks and we can evaluate from there.

 

Tim, I have something in mind and have been planning it for awhile. There has also been other dyno testing done on another vehicle and will let you guys know what I find out.

 

Unless a guy was greatly overspinning an eaton there is nothing to be had in upping the flow rates through the stock IC (under blower). Just keep the stock pump clean and it'll be fine. (with age it may degrade and need replacement)

You guys running turbos, and aftermarket blowers would'nt stand to gain anything in my (undocumented) opinion.

If a guy is really bent on upping flow rates? Why not just increase head pressure to achieve the same effect?

But hey, what do I know?
