Do you have the ability to post a video or two as well?
I have one of it flexing the suspension on a loading dock, but none of it driving, yet. I'll take video at the dyno, on Thursday.

I set this to "public", so everyone should be able to see it.
VIDEO OF DYNO
lower blue lines are from when the engine was naturally aspirated. Double lines are two turbo pulls.
6PSI of boost, 92 octane pump-gas, 4.2 bottom end, '92 4.0 head, stock 4.2 cam, 2000 intake, Megasquirt MS3Pro w/ distributorless coil.

Is it me or does the "100.86 HP" seem a bit odd?
A stock 4.2L 258 with a stock 4.2L head made around 150 horsepower at their peak. With drive train loss factored in that number is not far off.
for clarification sake- the NA 100HP pull was on the same setup (4.2 w/ a 4.0 head). It was running the factory EFI/computer from a '92 XJ.
Great turbo write up.I have the tools and experience to do this...and want to...except....I have a nice rust free 99 two door....But NY state plugs in the ORB2 vehicles to a computer during the annual state inspection...So I have to find a way to cheat the system. Or sell it and buy a 95 or older that they don't test....I don't want to sell....
I have the same jeep. So you think a turbo will not pass the emissions inspection?
Done correctly, an FIC with the turbo should handle the extra fuel and air, and have the ECU not throw any codes. The FIC is designed to intercept the signals and tell the ECU what it thinks it should see even if the engine is doing something different. For the ignition retard, the FIC does nothing more than add a delay to the crank / cam signals so that the ECU triggers when it thinks it should. Same with the injectors - the FIC will pulse the injectors longer when the ECU triggers them, and the ECU thinks nothing of it.
What are you guys running for timing under boost? Does anyone have a picture of their timing map they can share?
