Icdedppl has 10-71 blowers on his 540s. Hes underdriving them, making 6 or 7lbs of boost. We were out 2 weeks ago, running the boat. I watched his intake air temps while he drove. The intake temps, were 135ish at full throttle, and most of the rpm range. They dont even begin creeping up when you hold the throttles down for a while. No intercooler on his setup.

135* isnt all that bad. Most on the internet hear the word "roots" blower, and immediately start talking about 200+ intake air temps, usually supported by zero actual data, jusy what they heard. The style and size of the blower has alot to do with it.

Overall, im not super impressed with my superchiller intercoolers. My intake temps are in the 110-120 range, which for a roots is not too bad. Realistically, they prob knocked off 20-30 degrees from my iat's. I got a good deal on them from a friend, but not sure id invest 3 to 4g on them for my setup if i was buying new. The superchiller also puts a big restriction in the intake tract, which requires you to speed the blower up to overcome that.

Id love to see what the intake temps are , in say, a non intercooled 177 blower setup.

Interesting. my engine room is below the cockpit floor the the air has a long concoluted route to take ... bet my temps would be stupid high herein sunny florida

Yes some do and some don't deepens on the HP and who did the motors. Have a 6v92 in my shop uses engine coolant to cool charge.

Thats a Detroit no ??

Yes it is. A 8V92 towers Johnson 710hp has salt water through the intercooler before the blower.
The 6V92 has only a after cooler in the block under the blower. Think the tempter after some turbos is approaching 400 degrees.
