so many rads and so little air flow!?
For some reason this silly dream on me being able to find the time and money to supercharge my car keeps rolling on. I now have pistons, rods and
potentially and super charger. Im now realising how obsessive this car thing can really be!!
Any way. I was thinking last night about where and how im going to mount everything and realised ill have more radiators in my car than your average
2-bed flat!
Main water rad
Main oil rad
Charge cooler water rad
Supercharger oil rad ( I assume this is required)
This is not an unusual set up. So where and how have others done this. Can I combine the 2 waters? I certainly cant do the 2 oil.
I was thinking for the SC and Charge rads ill run ducts from the behind the main rad to flared side panel exits where they will sit.
Any thoughts or pics of a 7 with these?
Track days ARE the best thing since sliced bread, until I get a supercharger that is!

You can't combine a chargecooler rad and the main water rad otherwise the chargecooler will be running at over 90 deg C when you want it around
10 deg over ambient tops.
If it is a Rotrex it uses special oil and filer/cooler/header so that is stand alone as well.

this is mine,
i run intercooler, water rad. turbo rad, then oil cooler
works fine, will need larger oil cooler or to swap its location with the turbo cooler for track work i think but that easy as there the same width

... and dry sump tank behind that. I am supprised the 4th rad gets any flow!!
Thanks for the pic, shows that just stacking them up is an option. I will be mainly track and hopefuly pushing hard. The 4ages run hot aswell so flow
and colling is important.

dont forget there is a lot of air running through them all, my engine is also a hot runner as standard, i see oil temps of 100-105 when driving
hardish on the road with the current setup, i have the ability to add another litre or so of oil though which i will be doing which will help

I would use an intercooler rather than a charge cooler.
Less to go wrong with pump etc.
Better heat exchange.
Cheaper. Much cheaper!
You can get combined water radiators and intercoolers that should fit.
This is a good build to see how it's all packaged.

Intercooler packaging is tricky on a 7.
Various solutions but the neater ones all require custom fabrication which is expensive.
MR2 and MX7 both have intercoolers that can work, but its tricky.
Much easier on Phoenix!

Mine
 
intercooler
Oil cooler sits behind intercooler, no need to cool an eaton supercharger.

How do you get flow to the top rad in your pic mark?
