I agree with Rick there is another thread dedicated to the "advertisement of product".
Like other users, I would get off the go pedal when the temps rose. I never got to puking coolant, however I did spend extended periods of time with oil at 300 and ECT at 240+ in 85-90* weather. This was with the following mods. CAI, No Cat, No EGR, Stacked Seals and Shrouds, Edge on Level 2/2 and Boost stick.
Since that time I have added the V2, it has shrouds and an electric fan, removed the previous shrouds and left the rest of the truck alone. The results couldnt be duplicated on the next trip, the OAT was above 98*, the oil temp high was at 240 and the ECT could only get to the 211 range.
The second run was on the same highway in the same direction, the results:
OAT = 10+ degrees on trip 2.
Fan engagement down to 1 for trip 2 vs. 65% of trip 1
ECT down 30*
Oil temps down ~55*
EGT down 140*
Average speed was up from 61 mph to 68 mph.
MPG up almost 13%.
A/C appears cooler.
Transmission runs 10* cooler (factory gauge)
I suspect the shrouding kit with the V2 creates better flow through the stack, which helps the EGT, A/C, and transmission temps.
I have seen pictures of the EOC and it appears to have a similar shrouding kit included, end users of this have also reported cooler A/C, EGT, and Transmission.
Neither solution reduces the heat created, they are designed to aid in heat rejection. Both kits have addressed thermostat controls for cold weather operation. The V2 is using factory tstats and the EOC is using external devices.
FWIW I am happy with the results of my truck with the V2, I now run out of engine before I run out of cooling capacity.
