My 3.2SS The final Chapter - It runs

[jpnovak]

First, a link to previous posts on the build. I rebuilt the top-end due to head stud failure.

3.2SS continues - Part III - the assembly

A few weeks ago I was able to get the motor back in the car. Last week I finished wiring up the motor only to find that my Crane optical trigger was not working. Late Thursday night I sorted it out. (Read: A new one was delivered by FedEx Ground).

So I connect the ECU, disable the motor, pull the top plugs and spin the motor with the starter. I was getting about 1.2-1.3bar of pressure off the starter. Enabled the engine by connecting the ECU and installing the plugs.

I was not expecting the motor to start right away. The motor took half-a-turn and fired to life. I was a little freaked out and shut it down quickly. I am not sure why. 10 seconds later I fired it up again. Once it was running I stabilized the map and it was loping along at 2100 rpm to break in the cam. It was running a too rich to explain the loping. After my 25 min cam break-in I made some more changes to the EFI map.

Here is the result:



now I need to reset the AFR at idle, balance the throttle shafts and lean out the acceleration enrichment.

I am so stoked right now. I don't know if the high is from the unburned fuel vapors or natural euphoria.

Not a drop of oil anywhere that I can find.

Excellent: There is no better feeling, at our age!

Your brave setting up a video for the first crank!

Truth be told that was after I did the cam run-in.

Look forward to seeing it in person, excellent work.

See you soon.

Thanks guys. Yes, the plan is to have it on the road for the New Year's drive. I need lights, door panels and seats.

Bob, Are you headed down for the drive? We could find a location to meet off 281 if you want to come the back way.

I just saw the e-mail so I have not yet had time to check schedules, but I will try to fit it in. Will let you know.

Jamie,
Congratulations! i can't wait to share the road with you on the 3rd. I sure hope the weather holds...

That is a really impressive project. I know you have untold sweat equity in that machine. You can be justly proud when your lap times pay the dividend for your work.
