I am pleased to report my 2 year project to get insane power from my 1.8t powered IM is done.  Dyno plot and engine bay pic tell part of the story.  The details are:

 

Base car: 2008 build IM 356 1959 Conv. D Roadster

HP / Torque: 168 / 170ft lb

Turbo: Stock K03 Air to Air intercooler

Boost: 15PSI

Fuel and Ignition: Stock Bosch ECM

Weight: 2300 lbs empty

 

Upgrade:

Turbo: Turbonetice T3 Super 60

Boost: 20PSI

Intercooling: Air to Water custom integrated into intake manifold, radiator in left rear fender well with active fan.  Oil cooler in left rear fender well.

Fuel and Ignition: Megasquirt with custom timing and fueling map.  MSQ also controls boost levels.

 

Result: 294HP / 236ft lbs @20lbs boost

What kind of a transaxle are you running???

 

Very impressive build.    Over the summer I modified my Subaru engine in my sand car and at the rear wheels I got 300 HP/278 torque on 8 pounds of boost and on 91 octane pump gas.   The only problem with that much HP, I broke my ring and pinion in my 091 VW bus Transaxle.    

 

I just got done swapping out the transaxle case for a much heavier aluminum case (stronger) and all the gears are now high dollar Weddle gears.  It's suppose to be able to take 300 HP so we'll see on my next trip 12/28/13.     

 

 

Tom,  Don't think I'll need it as the power comes on pretty smoothly right now.  I am not going to do any high RPM launches anytime soon.  Drove it today on the interstate from Griot's in Tacoma to my home in Olympia (picked it up from my builder at Griot's and showed it off a bit).  Pretty calm until you hit 4500 RPM then, WOW!  60 to 90MPH is very quick.  Need to adjust the boost control to raise the boost at lower RPMs a bit but, other than that, its really good.
