Bloody hell! They both look like they mean business!
This has been an issue for turbo road race cars for years. As soon as you separate the cooling air flow paths of the Coolant and the intake air you make live easier.
If you think about cooling anything you need two things. 1) mass and 2) temperature difference. By removing the cooler for the supercharger you are in effect improving both of the above! You get greater mass as there is less air restriction through the rad AND you get cooler air as it's not ore heated by the HE!
Also the HE now gets it's own load of cool air rather than sharing the air (less mass only with the HE as it's at the front of the cooling pack) with the rad. So it's a win win.
Also these guys did he same thing on the mad ZR1 above and it worked a treat! They could thrash the car all day and never had ECT issues or intake temp problems.
Also with this system you increasing water flow rate through the intercooler system. This is another major hold up on most OEM water to air systems (and was a major issue on the ZR1). If this system really is increasing water flow rate by 30% then that's only going to help!
Some of the ford GT500 guys have found that their stock system was flowing Water soo slow that it was turning to steal inside the intercooler! Obviously this is not an issue (the steam will turn back to water once the system can remove the energy, ie when you let off) it will reduce the efficiency of the intercooler. Not sure if this happens on the C7 but it's pretty interesting.
I've been trying to chase this picture down to understand how those side coolers work on the C6. Odd choice to upgrade the intercoolers instead of the radiator system. I understand the radiator is now no longer blocked but I don't think a thicker radiator is sufficient for this generation cars. If the charge air is cooler but the coolant is over 230* timing will be pulled anyway. Does TIKT or Katech have a complementary solution for coolant temperatures? I see the C6 is used on the track but this mod on the C7 strikes me more of a drag racer setup. Nothing wrong with drag racing btw, just looking for solutions for myself.
LG's solution is essentially an upgraded radiator and intercooler, with their I/C still being in front of the radiator. Even so, LG are reporting large decreases in both water and engine oil temps on the A8. It would seem logical that perhaps even lower temps can be achieved by relocating the I/C(s) out from in front of the water radiator.

Yes there is a cooler on both sides and both sides will have the same vent opening on each side so it looks correct.

Who knows! LG is secretive and the project is taking for ever. No PDR data. I saw everyone jumping the gun and saying that LG did it again. Did what exactly? Did anyone test their solution? No disrespect to LG or anyone but nothing is solid there yet. I also don't think it's appropriate to Hijack Ktech thread and make it about LG. I am not pro or against either vendor. I read what everyone has to say and use my common sense. Ktech solution seems promising so good luck with the project and hopefully it will come to life soon. There were other known vendors that promised a lot for Z06 cooling in the past and then went silent. Hopefully it's not the case here.

LG is believed and wouldn't be blowing that here. If he wasn't he would be going the Hennessey way real fast!
LG gave real world temperatures.
LG did incorporate the radiator, which, was part of the conversation.
Similar opening placements.....!
Options are good!

I have been talking to LG and Louis at GSpeed on the LG fix, as I understand it, their kit removes the intercooler from in front of the radiator, and does two smaller ones much like this design. I think the concept is about the same.

Top... continues with the flow of the headlights, lower looks like something a Lambo designer would do. Appears by 2017 there will be multiple cooling solutions available and tested for the Z06's.

The side units are smaller (LxW).
Anyway, it is nice to finally see a robust Z06 configuration coming around! Some guns don't shoot right out of the box.

I think it would be nice to see the top one with larger openings.
Jason, any pics of the exhaust side of the ducts? Are they dumping in front of the wheel or out the side? It would be nice to see some air speed data in relation to road speed for the new vents / coolers and the rad beofre and after.

I have a few questions regarding the system:
1. First post says there will be revise brake ducts. Where would they fit since the original brake duct inlets seem to be dedicated for the intercooler cores.
2. Are two expansion tanks better than one?
3. Is the increased waterflow from having two pumps lowering the intake charge temperature?
(2) and (3) may be obvious but I'm new to intercooler upgrades.
