Baffled by apparent reversion issues with Lightning headers and mild cam
#12
Since pictures are worth a thousand words, here are a couple of shots of the engine on the cart. This is the first test when I had the silent choice diverters mocked up. When I started seeing water in the tubes, I switched back to the original divorced collectors that have an inner pipe that effectively extends the dry part of the pipe and extra 9 inches or so. No change in the water in the primaries.
And here is a picture of the water that is showing up in the tubes. Like I said, it's not a whole lot, and so far no sign of any water in the oil, but this is after just a minute or two of idling at 800 RPM:

Here are a couple of pictures of the divorced collectors. As you can see, they have 4 or 5 holes in the tip about 3/8", and one in the bottom for water to come out. I was watching it run and it looks like a waterfall coming out of there. Seems like too much water to me. Might try to post a video of it running when I get my boogered up spark plug hole fixed (another story... )
I'm wondering if anyone can tell me for sure that the 5 holes go on top. Might have to call Lightning.

Thats quite a bit of water in there buddy. My tails are super short and I had a 'waterfall' in there too but as far as I know it never made it any farther than the collector getting all wet.
Either way I didn`t like it so I sealed up the water holes (slits in my case)with SIX10 and had a guy weld in a pisser just to keep the mufflers cool. 3/4" bungs inside and all water overboard.
Better safe than sorry.

I still have my Y-pipe in there. Toying with using that to dump the excess water instead of drilling another hole through the hull.
Can't believe I'm even having to worry about this with that mild cam and Lightnings. Leave it to Budman to find yet another clusterfuq. They just seem to follow me like a stray dog.
