"Version 1.0, 3-years ago, drew the air from between the heat shield and manifold. IATs were way too high -- 180F in the Winter! The faster warmups were nice, but detonation wasn't. v1.1 moved the tube to its current location, which is far enough away, but never broke 90F. Removing the shield allowed "v1.2" to reach 100-110F on cold days, 140F on 40F+ days (fall is a bit unpredictable). This is in combination with a rad-block and has worked well since."

RH77: Have you tried changing the gap, heat range, type of spark plugs being used to fix the detonation due to high intake temps? I had a supercharger on a toyota tacoma and the discharge temps of the s/c was so hot that it caused detonation that could only be cured with timing adjustment and/or colder heat range plugs. Just an idea.....
