Not sure if flow is more important or if dual pass is more important If we can get some more info here http://www.vx220.org...20#entry1738404 We might be able to solve a few things by putting a dual pass mod you reduce flow through manifold

Pump is now working again.

 

One of the connectors on the relay was loose. Will take it out this afternoon and see how i get on. Hopefully that was the issue.

I am on the original pro alloy cc pump located down low by the rear drivers side wheel arch, Air was always a problem till I started, using the connection on the pump itself to remove the air in the system. I lower temps than Bargi using a 3.0 bar Tmap sensor and smaller pulley, haven't figured that one out. Bargi had his laminovas cleaned by Vocky when the engine was sorted by him. My temps were lowered when I revered the wiring on the fans at the front of the car so they ran the correct way...... I will however be upgrading the cc pump just need to find a cheap but legit pump.

so did the log without the engine running and the temp stayed the same (13ish degress).

 

Been out and logged a run this evening, Temp hit a max of 48 and a low of 33, Sounds a lot more acceptable?

 

May well change the pump though (although will move it lower in the car first to see if that helps).

 

Thanks all

Chris

Also had a response from Peter. The two responses refer to the original file i sent him when the pump wasn't running:

 

 

I have looked at your logs, and it all looks normal to me. The high inlet temperatures are sort of normal for an Eaton setup.

When you are not pushing the temperatures go up because the Eaton is pushing more air out than the engine needs. At this point the extra which is not used by the engine is recycled through the supercharger again and this will generate extra heat which explains the high inlet temps while cruising.

 

 

 

Temperatures a little above ambient are not possible with an Eaton setup. These graphs probably were made using an inlet air temperature sensor before the throttle body (like EOM). When using the IAT sensor in the MAP sensor (TMAP) like you are, you will see temperatures well above ambient when using an Eaton supercharger.

Sounds like you have solved things with getting your pump running again Your temps are more reasonable/believable now Amazing how much is removed from the CC system

Thanks for the help Chris, much appreicated

Just had a reply from Peter with regards to my latest file I sent him:

 

Hi Chris,

 

I must say your inlet temperatures look very good. Normally I see temperatures a lot higher with an Eaton setup, it looks like your charge cooler is working very well.

 

BR,

Peter

 

Happy with that. So maybe it's best I just leave it well alone or else it will end up like my lawn mower (in bits and not working!!)

When my CC wasnt working I used to get 70degC+ inlet temperatures, now rarely above 30degC when driven hard
