Intercooler pump numbers

[canadian]

Was surfing some other sites today and came across this testing of different intercooler pumps:

Of note:

"The Bosch 1150 LPH PCA pump continues to be the baseline standard pump used in many liquid to air intercooler systems in both OEM and aftermarket applications. In the ZL1 system it flowed 3.6 gallons per minute (GPM). This is the same pump used in the 2009-2013 Cadillac CTSV, Cadillac STSV, Cadillac XLRV, 1999-2004 Ford Lightning, Ford GT500 and many other OEM applications. It is also the pump used in Magnuson, Edelbrock, Whipple and many other aftermarket supercharger kits. It is fairly compact, very reliable and has low current draw. It performs fairly well against an outlet restriction but doesn't flow as well as some of the newer, higher output pumps that are available. This same pump has existed for well over 10 years without any major design changes."

I bolded the part about it being the Lightning pump. Just to see where another common pump stood in the flow category, I went over to Ron Gregory's site:

Make your own decisions about which pump you want to use. I run the Johnson that I bought from Ron, so maybe I'm biased. Here's a pressure vs flow rate of the Johnson pump:

The EMP pump is badass, the price however is not! Good lord.

I use a CTSV Bosch on my Regal and it performs far better than the Johnson that's in my Ty. The noise level on the Bosch is also significantly more quiet than the Johnson as well. There is an article somewhere (CTSV board I think) where they installed two bosch in series, i was amazed at how much it flowed like that.

After reading those articles - and searching LPEs site -it looks to me that the ZL1 or Varimax is the best way to go now.

That all said, the V pumps can be had on ebay for less than a $100 in used condition, which is an awesome bang for the buck and an improvement over the Johnson.
