Thread: Knock sensor

Tweet

I have a question about knock sensors. I am currently building 3 street rods. A 1929 Buick, a 1937 Cadillac and a 1938 Chevy Pickup. All three of these rods will have 383 Strokers. One of them is a 92 tuned port and the other two are LT1,s. I have two of the engines finished and am waiting on the third to come back from being bored.

I am using block hugger headers and see that the knock sensors are so close to the collector flange the it will not be possible to get the wire hooked up. After studying on this, I am wondering if it would work to put a 45 deg fitting in the block and turn the sensor in a slighty different direction so as to clear the header. I have never tried to use a 45 degree fitting on a knock sensor before and am wondering how much less efficient it would be. My only other option that I see would be to relocate the sensor into posibly one of the threaded holes of the clutch equalizer bar. This would take it out of the water jacket and I don't know how less efficient that would be either. The last option would be to program it out of the computer and not use on at all.

Anyone had any experience with this??

Thanks, Ed

shouldn't matter where you put it, as long as it is screwed into the block, the new chev 6.0L have nock sensors located in the lifter vally. the elbow idea should work 2. you could test the relocation by monitoring scan tool and tapping on the block lightly with a small hammer to simmulate an engine knock
and see if it detects anything. good luck

I am running a tuned port motor with block huggers and I retapped the 3/8 threaded hole for the clutch ball to 1/4 pipe thread and it works just fine.

Right on!!! That is the information that I was looking for. I was debating on whether to put a 45 degree fitting in the water jacket or mount it in the hole for the equalizer bar.
