300CE TURBOTECHNICS DYNO REVISIT
LET'S START AT THE BEGINNING !
Published ratings for 1988 300CE M103-12V are 177HP / 188 Torque.
Baseline dyno done on 3/30/2007 was 136HP / 145 torque.
Pulls were made on a Mustang load dyno which indicates about 18% lower then an inertia dyno.
Drive train loss = 30%.
Turbotechnics kit installed with only mod being the application of a Split Second stand alone controller to fire the two additional injectors.
KE-Jetronic and fuel delivery system remains stock.
5/24/2007 dyno pull 196HP / 221 Torque.
After I got the car back I replaced the supplied intake and boost coil hoses with silicon and aluminum tube.
The supplied Fram panel filter was replaced with a K&N filter.
The R16 resistor removed to pull about 6 degrees advance.
Today I put it back on a Mustang load dyno to see what my mods produced.
1/17/2009 219HP / 254 Torque.
The AFR was great under boost at 11.9 under full boost.
What was noticed was that the boost was only at 6.2 max with an average of 5.4
So about two turns on the wastegate linkage on the Garrett T2's and...
261HP / 302 Torque
This is at the rear wheels.
Max boost now 7.3 with a 6.9 average.
Add back the 30% drive train loss and it's at 340HP / 393 Torque.
Torque is significant...back end goes out with any hard throttle on the 2-3 shift !!!
More boost ???

30 degree just too cold for the tires.
The Mustang load dyno I used also has a Christmas Tree option...just like the one at the track, so you can run a fairly accurate 1/4 while on the rollers...
I'm guessing with traction low to mid 13's around 104+
All drivetrain is still stock....transmission shifts strong, in fact better as the boost curve is almost linear...it was dropping too much at shift points before the wastegate adjustments were made.
You really need a dyno to set up and tweak a turbo installation....

NICE! I see you removed your passenger seat for added VRRROOOMM-ism.
Your car seems to be leaning to the left though, you should get that checked out

Zorro would understand as he is not a "philistine"
