Dyno Run

scanned image of my Dyno Run from KSP.
328.4 PS at the flywheel and 293.1 at the wheels.

Engine mods are as follows.

Knight Sports High Flow turbine .8kg/m boost
Greddy FMIC 2core
TB Mod.
550 pr. 720sec. injectors
Nismo R32 GT-R fuel pump.
Apex Power FC.

This run is using mostly the base maps with the Power FC. I have made very little changes to the fuel curve and nothing with the timing on this engine.

Feel free to discuss it and give input.

good job. How do you like your PFC so far? Im going to be running it in my black 89 T2 Cosmo.
I just put down 263 at 9psi with the yellow car on the stock ecu a month back. Im working on getting the haltech running good enough start really beating on it.

Everything looks good for your mods...
Do you have a boost controller?&nbsp The graph looks like you have no boost control on it - the power falls off at around 6,700RPM or so.&nbsp With a boost controller, it should make power all the way to redline.

It looks like you're running a tad rich from 4,000RPM to about 6,000RPM...&nbsp You happen to have a wide-band O2 on it during the run?

I really like the computer. all I need is a some more knowledge to reall make the power and response.

I have a boost controller (profec B) Yeah the peak power was made at about 6500RPM and by looking at the data sheet that came with it my boost slowly drops off after this point. I think my actuator is just too old to keep up.

Sorry no wideband o2 sensor on the run but I am sure it is rich in the midrange and I am slowly working on adjusting the fuel curve.

Thanks for the input.

How'd they figure only a 10% drivetrain loss? Seems a bit low...

I get 10.75% loss.&nbsp We don't know what kinda dyno system (Bosch?&nbsp DynoPack?) Ranzo used.&nbsp I know the DynoJet's run down to about 12% for rotaries with Redline in the drivetrain...
