Hi there


Really as per title has anyone fitted an uprated charge cooler / intercooler to their F-Type.

As I do drag racing am thinking it could help with keeping the engine delivering peak performance.

Wondered if anyone here has one fitted and if they would recommend it?

The F-Types already have an inter-cooler. Did you mean to ask "Has anyone fitted a LARGER inter-cooler"? If so, then there are a number of existing threads that outline where you can order other options

 

There was talk some time ago about a larger radiator for the stock intercooler but I don't know that anyone ever actually tried it.

The intercooler itself is going to be difficult to upgrade.

 

Yes I meant larger.

 

+1. There is no room under that intercooler cover to enlarge the heat exchangers (2). With a redesigned deeper cover it might be possible, but I don't think there is much room left between that cover and the bonnet as it is.

 

I have acquired an unused upsized Viezu/Paramount IC radiator from a fellow forum member and want to analyze the benefits. Any idea where and how best to measure either coolant temps or post SC air temps?

 

Pictures please.

 

Not yet installed. I’ll take before/after temp measurements.

 

BUMP: Please help. I need some ideas.

 

I think there are many variables in play and trying to get some graph that definitively quantifies the improvement is going to be difficult, to say the least.

I'll note my experience with my previous car though, as you're looking for ideas. The intercooler there was air to air, but if you step back far enough that's irrelevant. I had noticed that when the weather heated up, if I made a number of successive accelerations the response and power seemed to get softer with each one. I suspected the intercooler was inadequate and would soak up heat with each pull and lose efficiency. I replaced it with a larger one and the problem was greatly reduced. I did not do any measurements to quantify this but some metrics do come to mind.

Perhaps the simplest would be to log intake temperature over a number of accelerations. If the intercooler were doing it's job properly, five runs of 3K to 6K in 3rd gear should show the same temperature readings. If the intercooler is not efficient enough, each acceleration will show increasing temperatures.

That could be logged through the OBDC port using existing sensors and would show how things are working as a whole system. Measuring inlet versus outlet temperature of the intercooler radiator will give some indication of the effectiveness of that radiator, but not what that actually means to the driver. It would also require adding sensors and measuring equipment.

 

This is what I suspect. I’m trying to figure out the easiest way of doing this.

 

Maybe something from these guys could be rigged or done manually (just spitballing here).

Thanks, Vince.Certainly offers some thoughts, though I’d be looking for similar and far cheaper versions elsewhere.

 

I've used an inexpensive laser thermometer to measure the surface of mechanical equipment but I expect you are wanting to measure liquid temperature.

 

I used a laser thermometer to measure surface temps with engine cover on and off. Gives an indication of improvement but not of what’s going on where it really matters. I’m looking for something to measure fluid temps ( either air or coolant), and also looking for a convenient location to place a probe without having to drill and tap a new hole. Is there a metric available at the OBD that might be helpful?

 

Thank you. I was tempted to do exactly the same, but concluded this to be a log shot.

 

I have seen tuners looking at intake (outside) air temperature vs. compressed air temperature when creating custom maps, but I don't know how they measure it. I think exhaust pre-cat temperature will also indirectly tell you intake compressed intake temp value (as heat from combustion burn should be more or less the same). So if you can read these values with an OBD tool, put the car on dyno (I don't think doing this at idle is meaningful, you need to apply load), feed the engine controlled temperature air (5 degree increments, you can probably do this with a duct, thermometer, and a heat gun/fan combination) and determine the point where internal temps (whichever way you measure, actual, coolant, exhaust temp) start to climb. For example, if stock is OK for 3 mins at 120F, but 1.5 min at 130F, but upgrade is OK for 3 min at 140F, you know it offers improved cooling.

 

We use these temperature loggers at work, and I bought one with the external thermocouple for a house project - you’re welcome to borrow it. Just have to figure out where to mount the thermocouple and logger.

Your methodology seems to be sound, but the car has to be moving at speed to properly assess the effectiveness of the radiator. A shop fan just wont be sufficient. I have an open freeway nearby where I can do some acceleration runs to see what is happening. The big consideration will be to conduct the before/after in similar ambient conditions.
Thanks, Dave. I will probably take you up on your offer.

 

I would think there will be a post supercharger inlet air temp sensor and an ambient air temp sensor that should both be accessible and loggable via obd port and a suitable app.

This would show temperature drop and hence intercooler effectiveness.

I believe the air to water intercooler water pump Is switched by ecu and would expect it's enabled when a certain post supercharger temperature threshold is reached
