Some water pump will make so much noise that it may drive some people crazy, like the one that Vortech put in their kit. I had no problem with the noise since my car was pretty loud already.
Can someone confirm that the pump on Ebay is really a CM30 (as advertise) and not the weaker built CO30 which has the problem of premature leaking. I also bought one, hahaha. I have a brand new CO90 if anyone wants to buy it now.

I bought it, installed it and it is indeed the CM30.

it looks like I missed out on the Ebay purchase.
Any body has another place were we can buy them for around $80?
I e-mailed the Ebay seller to see if he has access to more pumps.
Summer is almost over.. but my car is finally working properly.
New SC clutch (newer design)
New trans
New torque converter
the transmission is still a bit sluggish at times.. but overall its much more precise than before.
Now I just need to keep my ITA temps down with these ASP pullies.

Why does no one mount a seperate fluid resevoir in the car and seperate the two cooling systems? It's got to produce much lower IT's and ET's
I work with some turbo Drag racers and they ALL mount seperate fluid resevoirs in the car to cool the intake air. They fill them with ice and water before each run and intake temps are usually in the 40 degree range even after a 7 second pass at over 200 mph in 95 degree weather. In fact, IT is one of the most critical components of a good run besides traction.
I'm sure I'm not the first to contemplate this mod, so why does no one do it?

Johnson CM30 and CM90 have magnetically driven impellers. CO30 and C090 do not. Instead, they have a mechanical seal that needs to be replaced often. On the CM pumps you don't have to worry about seal going bad. There's instructions on how to replace the seal on on the CO90 pumps on their website.

btw, i'm not the only one who's done this with their 55.unfortunately, we'll NEVER be able to cool iat's as efficientley as custom air-to-air i/c's do but we should at least be able to get much closer to ambient.

NOW THAT'S WHAT I'M TALKING ABOUT! Very nice looking installation. How much of a performance gain did you see over the stock system. I'm betting it was signifigant?

iirc, rflow has shown a significant decrease in iat's from his.

However, you are right for the daily use off the track then the air to air will be more efficient than water to air because it will not be practical to use ice for the water to air application.
