The CSX: October 12, 1999

by on Oct.12, 1999, under CSX

For the first time in a while, less bad news.  🙂  I finally got the Conquest intercooler installed last week.  I found some 90-degree 2-1/8″ I.D. hoses for the connections under the front cross member.  I found them at Trak Auto for some kind of Ford van.  The rest of the plumbing consists of mandrel-bent and straight exhaust pipe.  The turbo-to-intercooler run is two 2″ mandrel bent pipes and some straight hose.  The intercooler-to-throttle body run is two 2-1/4″ mandrel bent pipes and a long 2-1/4″ straight pipe.  All connections were made with bits of truck radiator hose and many stainless hose clamps.

Now that this car is intercooled, I return boost control back to the logic module.  So now the 16psi ND computer can do it’s thing.  No more pinging at 13psi either.  While I was at it, I relocated the MAP sensor to the firewall right next to the brake booster.  I made an aluminum heat shield to protect the sensor and solenoids from the turbo.  I took great care in replumbing the vacuum lines such that critical sensors will not be effected by other vacuum devices.  These include the MAP sensor and fuel pressure regulator.  Now the funky fuel curve problem is gone.

The setup worked great for about a week until I started getting problems where the engine would QUIT just as I would start to accelerate.  I also noticed an erratic idle speed.  I have have always had a code 15, so I just unplugged the frickin’ speed/distance sensor–problem solved.  I don’t have cruise, an automatic, or electronic speedometer, so the usefulness of the sensor is questionable anyway.

In other news, the piston slap is as bad as ever and the engine is consuming oil, though I don’t notice any smoke or smell at all, nor do I see any in the coolant, etc.  I loose about a quart every 1000-2000 miles.  I’m sure it’s just the rings.  Blow-by is horrible…the dipstick isn’t blowing out, but it is very tight in the tube.  Oil is coming out of the oil cap and it just recently blew some RTV out of the valve cover seal.  Due to the Shadow’s current condition, the Shelby is now my daily driver.  I hope it holds up….
