Intercooler efficiency

[Davezj]

No I didn't cut my crash bar to fit my 600x300x76 intercooler either.
Just a bit of creative bracket making and metal bending of the bonnet release catch support.
No crash bar spacers used either.

Oh and by the way - once I finish putting my Legnum back together I should be able to share accurate temperature difference readings (eg. plotted vs boost pressure and throttle position) since I have now installed thermocouples before and after the intercooler (600x300x76). Even bought a differential pressure sensor to go with that, but I'd rather get the car back on the road first.

That should prove interesting, some actual data will be very welcome.

You don't have to cut the crash bar, not unless your intercooler is thicker than the standard 76mm...

This is the size or the HDI GT2 intercooler
I really don't think that it would fit without cutting of the crash bar tho.

I see, so the HDI GT2 is quite big. You can fit a 600x300x76 FMIC wihtout cutting anything, either space the crash bar by 6mm or massage the bonnet release catch.

I have been planning a similar setup but one question. How are you going to log the temperatures?

I plan to use a Raspberry Pi to talk to a thermocouple breakout board. The Rpi would do the logging, it will be a DYI project. I don't see anything off-the-shelf and sensibly priced that I could use.

I did the initial setup to use an arduino to do the monitoring inlet temps through a T/C board. But got board part way through when I bought one of ghost UTCOMP boxes that had 2 temp probe on it anyway so no need for arduino. Then the UTCOMP broke and that was the end of temp measuring for me.

I suppose I should go back to it at some point as I have spark plug temp sensors to keep track of individual cylinder temps.

How do those look like?

Edit: I guess something like this. http://thesensorconnection.com/cht-s...e-12-and-14-mm

I was trying to have a company in Poland create something similar, but they were not willing to invest time & resources to create just a few pieces. It seems that these can be purchased though.

For me the spark plug temp sensors give a close approximation of CHT so could be very useful in determining the quality of a tune and likelihood of knock.

Yes I have pretty much what is pictured in the link.
K-Type thermocouple on a ring that will sit under the spark plug.
Probably have to remove the crush washer from the spark plug as it is about the same thickness as the thermocouple ring to ensure the plug still goes the same distance into the cylinder.
I bought my thermocouple with a 14mm ID ring. Just need to make sure they will fit down the side of my coil packs.
But that is something for another day.
