That one does look nice. I think the next one I get will be a 3.5" thick one though for some better cooling.

 

My AIT using OBD2 scanner is constantly between 135 Cruising to 175in traffic with 80f+ outside. Now that temps are 60 and below those temps are obviously down now.

 

When it is 80-90 degrees out my IAT's are about 110-115 cruising and 145-150 or so in traffic. I have the stock vortech water pump with an ebay heat exchanger.
With temps in the 60's or so my IAT's are under 90 cruising.

 

Guys i will post pics soon of my new setup its basically a new radiator, re-routing and pump for ~$200

I have quite a bit of experience with cooling cars with F/I and helping with cars in my mates tuning shop, there is a Lotus elise with a turbo and charge cooler setup we fabricated from scatch. I'll post pics of that 340BHP monster in something that weights 750kg.

I am running a 3" pulley so overspinning the blower 'just' at ~8600rpm, the blower will be just outside its efficiency range and thus create a lot of heat, I'm making 13.7psi @ redline.

I have drilled and tapped the mouth from the AC and reinstalled the IAT sensor there, it does help with heatsoak it is not a massive massive improvement but it has definitely i guarantee helped and i would recommend doing it. I have made a blanking plate etc, the temps are quite accurate and when not heatsoaked the same as stock so thats good for us piggyback people who dont have great control/adjustability with iat correction tables in a standalone ECU.

I'll begin by the saying the core in the aftercooler is not big enough to support high boost on the novi1000. I was seeing heatsoak so temps would be 30c cruising and then easily get upto past 60c at redline in 4th gear with the stock pump and stock CT heat exchanger, it would take a while to drop too.

I have installed a bosch cobra pump that is 0.3 bar and moves around 23 litres plus re-routed the plumbing, the stock setup as per CT is no the most effecient trust me on this . The pump is only good at pushing IYKWIM so the output of the pump is routed to the port nearest the throttle body on the AC housing, out from the bottom port on the AC to the top port of the radiator and from the bottom port on the radiator back to the input of the pump, it gets two chances if you know what i mean and most heat is passing in this area (near the TB).

I have also bought a radiator that is used for a fiat cincquento to cool the engine, when choosing a radiator you want it thick but not too thick and be able to just about 'see through' it so air can get to the cores and pass through some i see are just too densely packed.

Do people see the IAT's rise as you go through the gears?

In a nutshell i can get cruising down to 24c and in WOT instead of hitting say 62c in 4th @redline it is now around 55c. You will all see the IAT's rise as you go for the gears, so roughly when the car has been out for a little time with mixture driving the iats are 12-13c above ambient. I need to work things out more as its just finished and bled but this is rougly a cooling improvement of 11%.

Okay not a massive improvement but I'll gladly take this than what i was before.

Will post pics soon.

 

Nice, I was wondering how everyone was plumbing their cobra pumps.

 

I had similar set up...novi 1000, 3 inch pulley, after cooler and a spearco front mount rad. I am in NC and during the summer see crazy high iat's. I changed the crappy little water pump that comes with the set up to the bosch pump...same one they use on the mustangs. I saw very little change in temps. I have a aem iat sensor that I was going to install in the after cooler right before the tb...but if it did not help you...then I am not going to waste my time. I think I will just install the sensor in the stock location...supposedly it is a better sensor and because of the internals...changes readings faster. Thinking about having a custom aftercooler fabricated...not sure if bigger would help that much?

 

I've got a uprated bosch pump on order from ebay.

I've also looked at the options on front mounted heat exchangers.

I think I'm going to get one of these as I want it to look the part aswell

I was going to get one of the ebay ones, but shipping to the UK is $150!!!! So after shipping it's cheaper from AVT
