I have since upped the boost to 21 psi, installed a 58 mm TB, raised the runners in the intake and ported for 58 mm, plugged a 1/4" boost leak, installed a custom Bell intercooler 2.5x the size of the Vortech unit, and destroked to an 8.5/1 363 cid (matches the turbo better). I haven't got the kinks worked out yet, but you can judge for yourself what it might make now.

Why not a little blue car history? I still have not got up to get a copy of the last file(no USB port on dyno PC) but thought I would share some history
I could not find all my old files
here is the oldest. post Blower explosion
Stats: junk yard LT1 with LPE 211/219 cam and 1.52 rockers, SLP CAI and B&B Tri Flow
Same combo with a Comp Extreme cam 218/224
next came a SLP Duel Duel ,12 bolt ,CSI electri water pump ,Hooker LTs and a GM 847 cam...mainly because the CXE cam expired almost taking the engine with it. This came with a 14 hour reserection with the help of JimBob and Ryan K
Same Combo with a 75 Shot. This was good for a 8/10th drop in ET!
now this is the same combo on the same exact tune with a earily set of Lloyd Elliot heads. this was the old 11 second N/A combo
NOW to what we got the other day. These numbers as well as ALL the other numbers were UN-locked. they may change once I get to analize the file with WinPep 7
Now to many that may look ok but my goal is some thing more like Jim's dyno graph here. we are still tuning on this one as well
We will see what the future holds. We have never really tuned on the blue car. I am going to try a few new tuning ideas on it.
I hope this helps a few curious minds

That's a good question because I've been thinking about either putting in the sportsman 355 or rebuilding mine with all the goodies, including forged bottom end and lower cr. I probably won't do it until something goes wrong with it though. I'm pretty happy with it as is, for now at least.
