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.

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
![](http://www.nwfbody.com/images/Ellis/Dyno/Ellis 350 LPE 211.jpg)
Same combo with a Comp Extreme cam 218/224
![](http://www.nwfbody.com/images/Ellis/Dyno/Ellis 350 CXE 218 224.jpg)
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
![](http://www.nwfbody.com/images/Ellis/Dyno/Ellis 350GM847.jpg)
Same Combo with a 75 Shot. This was good for a 8/10th drop in ET!
![](http://www.nwfbody.com/images/Ellis/Dyno/Ellis 350847 75 N2O.jpg)
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
![](http://www.nwfbody.com/images/Ellis/Dyno/Ellis350LEheads.jpg)
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
![](http://www.nwfbody.com/images/Ellis/Dyno/Ellis Base380.jpg)
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
![](http://www.nwfbody.com/images/Ellis/Dyno/Jim401Locked.jpg)
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.
