engine temp

[davyv]

Anyone know what water temp difference there is with a good fm intercooler (Apexi gt)  with and without the aircon rad on. I am just putting it all back together and am not sure if i want the aircon rad or not.
 The car will have a large single turbo so i want the best cooling poss, thanks.

I think it depends on the angles of the 3 rads and ducting but in general the difference would be minimal, with / without the aircon rad. If your going to be large single turbo id make the car light as poss,
 
i dont run air con, i have windows

On my single I have greddy front mount, with unknown rad (thick ally one though) and aircon.  The water temp is more controlled at a steady 82 degrees than my twin fd with v mount.

The greddy is front mounted, the rad is upright position (but slightly angled downward a couple of degrees) and the aircon heat exchanger is in the stock position.

Hope that helps.

I run an Apexi GT FMIC with a Koyo N-flo Rad, both in the upright position. I can tell that without the aircon condensor I see temps of about 82-84 degrees C.

I\'m also thinking of re-fitting the air-con condensor and think that I might need to get a new thermostat so that it opens a bit earlier, to help keep the engine cool.

However I think I may get a vented bonnet first to see if that helps.

Jib the air con, its costs power :mmmm i run with out

How?  Thought the aircon clutch disengaged on WOT?

to be totally honest i dont know, Dwayne ( from www.Lindopmotorsport.com ) did it when he re-built the engine, i know he made a load of blanking plates, dunno what for. :xconfused

Are you not getting mixed up with the airpump?  You need blanking plates for removal of airpump, and removing the airpump does free up a couple of hp.

air pumps gone to, but no definatly got no air con any more. funny really the more i spend on it the less that seams to be in there !!!! i will take some pic\'s later and post them up. :Talking1

[Kevin]

Ok cool, look forward to seeing them.

I think weight plays a part when removing the a/c, the pump is quite heavy and leave a nice big hole to allow a bit more air flow. Also the less restrictions the better for the rad and I/C IMHO

Where is the AC pump in a FD mine doesnt blow cold so i might aswell get rid

[memski]

Ac pump is below the Ps pump, 2 or 3 bolts to remove pump along with pipework, condensor and core in the cabin.

Echo that about fmic, I don\'t see any increase in water temps - may be a diff story on track but I haven\'t even added any ducting around the rad yet... (Hks gt core with fwin rad).
