the CM30 isn't cutting it

 

1. Meziere
2. split cooling circuit
3. killer chiller

 

Pump only, don't need the other items

 

what's the rest of your cooling setup?

 

Don't worry about it, I'm asking about pumps. and I'm not interested in the Meziere, had one...

 

They also make a CM90 don't they? I would try that

 

There's a thread around here somewhere comparing the cm30, mez, and bosch '010 pump with the bosh '010 coming out on top.

 

I think this is the post you were talking about Sterling E55

Meziere 100%. I had a problem with my heat exchanger and went from all kinds of setups and pumps and after putting a custom heat exchanger on and testing more I found a single pump in the rear with my trunk tank worked best. I would say the same would be true for having just that pump up front also. The best thing to do us add a trunk tank though honestly.

 

I have two mezieres on my system, one in the back by the tank, and one upfront by the HE.

I am using the Bosch 010 and have no issues

 

The Bosch 010 has been shown (flow wise) to be the best plug and play pump....

 

What is wrong ? Not reliable - having to replace frequently ? Supercharger running hot ?

The Bosch 010 is better than the CM30, but I would not replace a working CM30 with a new Bosch 010 as you won't really see any gains.

 

Meth injection?!
