Looks great, one question though (for now). Would it be feasible to tap for a 1/8 NPT pipe plug instead of using a self-tapping screw? That should seal much better without silicone sealant?

Okay, two questions.... How much injector would this SD pump handle? Would it let me run a 160 cc on a fairly aggressive chip without throwing a CEL??

I think that the 1/8 NTP plug would work great. I just did not do it because I did not think of it. [img]/ubbthreads/images/graemlins/rolleyes.gif[/img] [img]/ubbthreads/images/graemlins/rolleyes.gif[/img]

Regarding the SD HPOP, it is a crap shoot because some HPOP's are better than others of the same part number. Depends on the internal clearances I guess. BUT.. in general, I have heard that -most- people with SD HPOP's are running just fine without CEL's, myself included. I have held the pedal to the metal up a long grade in the extreme setting running 35+ PSI boost for over 20 seconds without any CEL and my injectors are 170cc's.
