The CSX: June 30, 2005

by on Jun.30, 2005, under CSX

Took the CSX to Ohio for SDAC15.  There was no way that my work schedule would let me finish it in time (it’s not even close).  Had an awesome time as always, except for the nasty hangover on the last day (oops).  The car did OK, though I couldn’t break into the 14s at all this year.  It just doesn’t feel right at the top end and the boost always drops way off.  With the wastegate disconnected, it can barely keep 15psi when I wind it all the way up.  I tried wiring the wastegate shut, but that didn’t help either.  At low engine speeds, it’ll crank out 20psi with no trouble.  Not sure what the deal is, but I do think it needs a bigger turbo.  I have that TU S60 with the .48 A/R housing and clipped turbine.  The Daytona’s engine has been collecting better toys since I got the turbo, so maybe it should get a true Super 60 instead.  It may be that I have the (modified) Talon BOV in the bottom hose and at high engine speeds, the IC starts backing up and the pressure in the lower hose goes insanely high and pushes the valve open.  I may try to remove the BOV and see what happens.
