- - lower iat mod (https://www.crossfireforum.org/forum/crossfire-srt6/78071-lower-iat-mod.html)

just installed 4 puller fans on the intercooler, for testing purposes. it lowers my iat 20 degrees farenheit during idling and stop and go traffic, Prevents and delays heatsoak and runs way better . it should work on c32 slk32 srt6 and maybe e55 depending on size of their intercoolers

Re: lower iat mod

looks good but that is the heat exchanger . the intercooler is under the supercharger my Iat's is 50 to 55 in the 9o* heat of today,,,killer chiller. jim

Re: lower iat mod

thats right ,and nothing better than killer chiller. but for a stock junkie like me and for 60 bucks in parts its good investement jeje

Re: lower iat mod

Great mod I was looking at the same thing since i have a aftermarket heat exchanger I was looking at 2 7 inch puller fans i only run about 20 degrees above ambient except waiting in the staging lanes Oh what size fans

Re: lower iat mod

Several years ago I did that with 4 fans also and decided that the change was not worthy of the effort. Thats when I made a bigger heat exchanger and then went to the aluminum radiator now known as the super cooler. The smallish heat exchanger does not allow the water to cool much as it has such a great rate of flow due to the small passages. Its location also is not making use of the engine fan to draw in more air.

Another thing that helps is with a split cooler design, using like 30% antifreeze and corrosion inhibitor allows better heat transfer. Antifreeze dilutes the waters ability to carry heat away. Enjoy, Woody

What size are your fans

those are 140mm fans, with high cfm and waterproof, dont use lower cfm fans, if you wants some I can lookup for the part number

Re: lower iat mod

Please do I will install 2 since my system is isolated and my IATS are only about 20 degrees above ambient so this would help at the track

the fan number is RL4Z B1402512-3M you should match the exact number, ebay has them. also if you use the stock exchanger don't ever put the fan directly over the fins, use a 1/8 spacer. I used 1/8 thick aluminum bar sold on hardware stores. also if 4 fans are used you have to shave about 3mm from 1 fan so its fit like factory
