Chris I think it might be the website. I'm noticing it on other pelican posts. They must be having issues. Normally use safari but also tried foxfire with no luck. Thanks

From here we could start playing with intercooler options and where we could put it so it would fit under the stock decklid. Eliminating all the CIS components created a lot more room.
  Then Levon had the brilliant idea to mount fans on top of the intercoolers since we won't have forced air from a close fitting rear spoiler.

At this point we were running Electromotive and we were about ready to run the motor in on the dyno. Things fired right up and Levon set forth programming the EFI. Within the early stages of tuning, the air fuel mixture went haywire and kaboom! Levon cought things as quick as possible but the damage was done. The result was two melted pistons and cylinders. We were armed with a mountain of data that pointed towards the electromotive system. Levon spent a lot of time sorting all this out....long story short, he rebuilt the motor and we ditched the electromotive in favor of Motec and from there on out it was smooth sailing!
I'm not here to point fingers at a particular product but what I can say is during the final tuning process, it became apparent that Motec was a far superior system with much greater tunability.

very nice build chris... like ALL of the work you do... can you share some specs of the engine internals for some of us that are now dreaming of making such a motor...ie:
what are the motor bottom end specs ie 3.2 or 3.3L or...? what engine compression are you running...? do you have a pic of the piston tops which I presume are flat...? how much turbo boost pressure did you have to run to get 590+ hp...? I would guess that in addition to the great work you and levon did creating this motor, that the "tweak" to the motec is the special sauce to make this all happen & to keep it alive for a long life... any general ball park costs to make such a complete motor pkg from intake, turbo, motor, exhaust, motec work, ect...? I would guess north of 25k...? thx for sharing what you can...bob

If anyone wants to build a turbo motor and debating on your management system, just look at this pic and then go spend a little more money and buy Motec.
 Levon took the motor completely down to the crank so everything could be checked. And then the rebuild process started again. You'll notice some new bits going on, including a twin plug distributor and an RSR crank pulley.   Then unpacking the Motec goodies and Levon took extra care to fabricate a beautiful plug and play wiring harness.

Thanks Bob,
As I mentioned before, the motor started life as a 1991 3.3L 965 turbo. P&C's are Mahle Motorsport 3.4L and you can see the piston shape in the photo above. Boost was set at around 0.8 bar. There were a lot of internal mods in the valve train, cams etc...but that is Levon's "secret sauce". The motor was designed to be very reliable and streetable. I was not on a quest for big HP numbers, but it was a pleasant surprise in the end!

Like I said, my intention is not to bash a company but it is hard to restrain knowing how much time and money this cost us AND the mountain of data that accompanied the event. The timing and A/F were all overly conservative. I won't go into details because they are above my pay grade but even Electromotive said everything pointed towards their product.
BTW, I've run Electromotive on other normally aspirated cars with zero problems. I just wouldn't run it on a turbocharged motor.

Well they only partially "owned up". Meaning they agreed that it looked highly suspicious and they replaced the ECU etc but we weren't going to chance it after that. We were on the hook for the mechanical repairs.

Back to the intercooler...
Levon called me one morning and said he woke up in the middle of the night with an idea to maximize the efficiency of he fans. He theory was that a decent percentage of the air moved by the fans was bypassing the intercooler by being blown back out the corners. So his solution was to build block off plates on any area not covered by the fans. The end result was a significant drop in temps. Final dyno runs showed inlet temps at 270 degrees and outlet dropping to 105...that 165 degree drop!

And then finally we are back to a fully assembled motor and back on the dyno for final tuning.
