when we were not using an intercooler, our air intake temps were around 375 to 410 degrees, as far as the situation about the cylinder heads, they required more attention because of the heat being generated not only by the engine being an air cooled, but by also the high air temps that passes through it caused by the hot weater conditions that we run at.(the only time we saw temps dropped significantly without the intercooler was when ambient air temps were in the 60's or lower....220- 140 degrees). As far as what you plan to run Rod, FYI, we run methanol for fuel, 90 hp shot af nitrous, single stage,with methanol(so far), an a combo of hilborne/waterman mechanical injection system at 40-44 psi of boost, the Lauffers also use methanol with a 2 stage nos system, but there set up is what your looking at, Motec efi system (wish i could afford that). Chad, i dont deny the fact that what you guys learned on the Bothwell's Garrett turbo mustang dont work, as a matter of fact that car kicks butt!, and also the engineers at Garrett are very knowlegable and obviously know what they are talking about because of what they do as far as r&d, but when you look at the fact that both the 2 fastest air cooled race cars in the world (also the 2 fastest EFI and Mechanical injected turbo aircooled opposed engines) both use "icepack" style intercoolers, you cant deny thats proof in the "pudding" so to speek, that the ice pack system is the way to go. Also i cannot see the difference between filling the top tank with 2 1/2 bags of ice, then filling it with 2 gallons of water and letting it sit with the ice waterthrough the core (drain tank on the bottom), is any different than having an ice holding tank,with a water pump to circulate it. In both cases you still have to drain the water after the run because the ice have melted then refill it prior to taking the next pass. Trust me I love those Garrett turbos, infact the next one i get will be one, but as far as i know, all their R&D an the killer racecars that they support have been watercooled 4,6 and 8 cylinder engines, not aircooled. correct me if not.

Water can transfer heat much better than air. The problem with an ice packed box is there are air gaps which actually act as an insulator. Only portions of the ice touch the metal to transfer the heat. It can work fine but using an ice/water solution should be able to transfer more heat if designed right and move that heat away from the charge. As mentioned there are trade offs with any system. If one system can get the job done without adding things like complexity, weight, pumps etc then it probably makes sense to use it. If you put salt in the water you can even get a cooler water solution than 32F (0C) of course the Al isn't going to like the salt solution much.
Try putting some warm beers in a cooler and load it up with ice. In another I will put my warm beer in and fill it mostly with water then add ice. We will see who is drinking cold beer first!

no i do like the salt ideapfer10 said:Water can transfer heat much better than air. The problem with an ice packed box is there are air gaps which actually act as an insulator.

anything to make a better working intercooler is kewl with me
i have thought about salt as well
the only thing i wonder about the salt is
even though its cooler
how does it affect the ice waters ability to absorb the heat
