I have just had a quick read of some of what was said here. Firstly the car tested does not have stock turbo's and made 270rwkw with inlet temps on the road test and on dyno of 60C with ambient around 26C. We know with similar cars with FMIC inlet temps and in fact a zed the very next day with our FMIC and same power inlet temps were at least 15c cooler. I apologies for those in USA who have read the Aussie forum and reading what appears to be a brush off from me to Zisluv. I feel I need to explain. It goes back over a year now of him constantly undermining what I do and attacking me and my business on a regular basis. He was recently banned from participating on the Aussie Z forum which there have only been two in it's the history of the forum over many years so go figure. He not only attacks me but numerous other enthusiasts on the forum and is generally disruptive. Anyway I agree that long tubes used in FMIC in theory is not the best and we have plans of making vertical core FMIC. Having more tubes has less pressure drop and is more efficient as most of the cooling is done in first half of the horizontal tubes on current design FMIC. In saying that the current FMIC we have which is an improvement on the earlier ones with smoother tapered end tanks, better more efficient core and mandrel bent alloy pipes in reality and from numerous tests on our dyno works better than all corner mounts we have tested, although not seen the Z1 type. The facts are that on our dyno the inlet temps with FMIC are consistently cooler than corner mounts. My own zed race car runs 550rwhp and 10.89 130.85 mph although it is mainly a circuit car and runs faster times at the track than any GTR to date and is very competitive.
