Air intake horn and H2O

Guys,

	I'm writing this in hopes that it gets through to you.  My email 
will sometimes get out, but I'm still not receiving anything.   I pulled 
this off the archives today, and just _had_ to respond.

Scott's right - that stuff doesn't just happen.

When I installed the EFI system on my 5KCSTQ, I was able to eliminate the 
entire CIS fuel metering head of course.   I put a 2" tube on the inlet to 
the turbo, and clamped a K&N air filter to the end of that tube out in 
the area previously occupied by the fuel metering head.   I figured that 
eventually, I'd move it down and forward to get it away from the turbo's 
heat or build a shield.   But I found the same thing Scott found - the 
intake temps were not that high.  So, I left it.   One other thing I 
found though was that in really heavy rain, when driving through a puddle, 
the splash would get enough water into the intake that the engine would 
stutter.  "Come on b-b-b-b-b-baby, _r-r-r-r-r-r-run_!" :-)

I know at Cadillac, we have (had, he was fired last weekend) a guy that 
does nothing but underhood splash development!  His job is to make sure 
the engine doesn't stall when its really wet outside.
