Ranking mods that reduce IAT's the best
My thoughts, looking for more experienced folks to comment. This could be used as a basic guide for folks & since the E55's biggest performance obstacle is controlling IAT's I figured it was worth a conversation:
1. Killer chiller (trunk or underhood tank) ~$??
2. Heat Exchanger ~$400
3. Split cooling (trunk tank) ~$??
4. Split cooling (underhood tank) ~$125
5. Methanol / water injection
Of course a pump is paramount but let's assume we have a fully operational one & does anyone have any measured results?
Not sure about the following:
1. Headers (they reduced IAT's a fair bit in other applications)
2. Porting supercharger (in Grand Prix's that used to net huge temp reductions!)
3. Bigger rad options?

Not that I've ever measured, but coolant carryover between the two systems is minimal in my estimation. Therefore, a split system with only the little reservoir in the engine bay is probably a waste of time and money.
A split system with enhanced capacity, that's probably worth it. (either through big tank, or multiple radiators.)
You forgot Methanol (or water) injection.
And big money: custom (relocated) intercoolers

No way!! A split system right off the bat drops temps down at least 80 deg.that I saw in my own. If your engine is running at 190 the inter cooler is already at that temperature so seperation from all that heat is a great plus right from the start even with a small tank....no?
If you look at how the two systems are connected, then you'll understand.
Check out the highly detailed schematic I attached.
The top circle represents your engine cooling, with the square being a pump.
The bottom circle is your intercooling system.

I find water/meth injection to also carry a big risk factor. If they fail, it usually ends up pretty bad. Overall, I agree they do a fantastic job of reducing IAT's & increasing power by allowing more timing/boost.

On my old car (3rd Gen rx7), I used water injection with great success... I used a mechanical pre-turbo injection kit. I haven't looked into whether it would work for a SC, but I don't see why not. In fact, it may work better since there's claims of pre-turbo WI damaging the compressor wheel... On a 55 SC, I wouldn't think that's an issue.

Centerline (who has one of the faster 113K's) suggested an "always on" I/C pump set-up in this thread. Makes sense to me but no one seems to talk about this. Does anyone know anything about this?
PS, I am heading down the meth injection path this will just be some "icing on the cake".
