Couple engine shots (yes it had hose clamps on those pipes when I ran the engine
)EDIT: OH you can see the leaky fuel line in the first picture.
Its the one that runs to the secondary rail, along the UIM/TB, down to the drivers side of the engine. Its leaking right smack in the middle of it, spraying all over the TB - WTF earls???????

LOL thats odd Jo, especially on brake line!
I couldn't figure this one out either, just replaced the section, all is well now.
But hey - you know how you told me to check WOT and make sure the TB was actually opening all the way? Missing horsepower etc etc.......well turns out, its not opening all the way
New throttle cable will be in order, and I may port up an extra throttle body to put on with it. I bet that was part of the reason boost was becoming ever more slow to respond, and the missing 20-30whp on the 18psi run. I had checked it at the beginning of last year, but the cable looks pretty worse for wear at the moment.....

Interesting B, so you're saying only having 80% throttle wouldn't effect power output? I'd tend to think that it would...
The exhaust manifold just has good ol reliable header wrap (DEI), the lower intake manifold has some DEI heat shield tape stuff....the intercooler pipes and everything black is just some high temp (1600F) ceramic spray balm crap. Looks nice but doesn't work well. If I have my way and get a powder coating setup to go with my newly discarded stove, I'll be powder coat crazy

Yeah you can check out the software for sure. If you want, its available as a download on the electromotive site.
http://www.distributorless.com/ (wintec 4.5.25)
Its fairly decent. Takes a little getting used to coming from haltech....but its working very well so far. I've actually found it very quick to get running half decent. Zero out the VE table and play with TOG and IOT until its running decent, then tweak from there

Looks awesome Joe! I was up in Hagersville yesterday, I was going to stop by but I realized you had already left for down south. Looking forward to coming up and checking out the car one day when you get back.

Wow.....
So its been a long time since I updated this thread
First - I have a few pics I'll upload soon of our Deals Gap trip, and subsequent Key West trip.
WE FINALLY MADE IT ALL THE WAY WITH NO BLOWN ENGINES
Next major update that I'll post up right now is the utter success of my tuning trip to Ohio.
I drove the car down to Logan @ Defined Autoworks for him to work his magic on the Dyno Dynamics. As always, its never smooth sailing.
On the first day, I had just got the car loaded on the dyno. Logan began making some base adjustments, revving the car in neutral etc. I'm standing behind the car talking to Peter when we hear this PING and the car stalls.
It fires right back up (with even pulses -phew! lol) but when logan lets the clutch out, the car's doing 100km/hr.........with the shifter in neutral?
Something inside the REBUILT TRANSMISSION has been jammed into 5th and won't let go. So progress was stopped while we swapped transmissions.
The next day, we got somewhere on the tune. But being inside choking on its own exhaust netted poor power, and a few shakey areas in the tune when the car is out in the fresh air.
So day three, we did it.
Here's the wastegate map (10psi)
Very pleased with the car even only at 10psi. Pulls like a train up top, and the power is very smooth. The graph almost looks N/A-ish he's got everything dialed in so nicely...
"low boost" setting on the profec (15psi)
On this setting the car really comes to life. I've pulled on a C5 Z06 corvette from a dig on this setting. Not by much, but I was making headway
And the high boost (19.7psi)
Now....as you see, this graph is all jumpy. My clutch began slipping at this setting, so we couldn't really get it totally dialed in. Personally, I think if the clutch held power would've been up even higher, but you can tell its barely holding the 380whp runs since this graph is essentially the same minus the spike from the over-rev when the clutch slipped.
So for now I'm driving the car on the two lower settings and *finally* getting some enjoyment out of her. A good tune and solid ECU go along way in keeping you happy.
One other minor point:
This engine is not the same engine I went to deals gap with. I had blown that one trying to tune up the Electromotive by myself when I got home. Which was when I decided it was time to stop playing "tuner" and pay a REAL PROFESSIONAL to do it.
Specs on the engine:
Same porting as before (same irons...near stock ports)
S4 rotating assy.
Mildly larger exhaust ports because I port matched to the replacement housing
I'll also add, that logan does tuning the way I would imagine it should be done. Loading on the dyno, cell by cell, one RPM point at a time. None of this "floor it, lets see what happens" stuff.
I've tried doing it this way (cell by cell loading) on the road, but its next to impossible without going through a billion sets of rear brake pads. There will always be some touch ups needed when going from the dyno to the street, but this type of load tuning gets things much much MUCH better dialed then simply letting the car wring out and adjusting the fuel to suit the VE of the engine. This way hits curve you'll be running through at full throttle - but also does EVERY SINGLE CELL inbetween. No subsitute for real pros here.
I'll be posting more detailed bits elsewhere and link them here. But later I will also post some of the pics from Florida and everywhere we went inbetween on our 7,500KM journey
Peace!

Great to hear you finally got the car dialed in. Are you gonna leave it as it is or gonna put in a clutch in at some point and try again. Either way, I'm sure your pretty happy with the car now that you don't have to think about the tune

When I get the ceramic seal engien together with my ported plates, I'll strap a twin plate on the back of it and shoot for +500whp on race gas. I think that turbo should do it with porting and 25-30psi.

So unless I went to the lengths of creating a mould of my existing one, producing a piece, modifying THAT piece to fit the car - then REMOULDING that part to start production......it would never fit right. Or at least, fit well enough for me to feel comfortable selling.
But you never know, stranger things have happened
