Got my first dyno run in yesterday. I'm pretty happy with the results.



According to their wideband O2 I'm running a little lean. Not sure how accurate it would be as they placed the wideband in the tail pipe and when I'm at full boost (10psi) most the exhaust goes out the wastegate dump tube into the atmosphere. Anyone have any experience with that?

 

Nice numbers!

What is your setup?

 

Nice numbers. Whats the setup? Also most dyno's put the sensor in the tailpipe.

 

90 Si with stock d16a6 (244k)
Thermal Research 3 inch exhaust
hf manifold and adapter plate
DSM 450 cc injectors
tdo5h-14b turbo
modified starion intercooler
1st gen eclipse BOV
custom downpipe with a separate wastegate dump tube
Zdyne computer
OPM limited slip

 

I love that FLAT torque curve. Great job!!

 

DAMN, that is one nice lookin graph. The power definately doesn't fall off at ALL up top which really surprises me. That thing holds nicely.

Great setup and best of luck. THose are great numbers man.

 

How much boost?

 

the 14b is stock actuated at 10 lbs so that's what I'm running. I've been tempted to get a boost controller and try 12 lbs, but I think I'd rather try to tune some more out of 10 lbs.

 

I totally agree. I can't remember seeing that flat of a torque curve... umm... in a long time--if ever.

 

14b's are stock actuated at 8psi. I'm running one.
