4.3 Supercharged Chevy

Ahhhh yeeeeah; She moves. BUT got some questions...

The DME apparently does NOT like this situation. The A/C doesn't click on because the computer doesn't think the engine is running (oh boy its running LOL). So I have to hard wire strait from the climate control box a wire to the A/C clutch. Does anybody here know off the top of their heads which wire kicks the A/C on?


Also, cause the computer is not getting all the info the cooling fans aren't coming on... Thats an easy enough solution. I'm just gonna get a thermo switch and hard wire them. Not really looking for an answer here; just sharing


And third problem. The Porsche designers didn't make the throttle cable long enough for an edelbrock carb. WHAT WERE THEY THINKING???!! LOL



Other than those issues... its fun. Just fun to be out of the garage finally. Even though I'm happiest when in the garage.

For the A/C: there are at least two points where you can hotwire the system: the A/C pump relay, and the A/C control unit. Based on the circuit diagram probably you can trick the control unit such that it thinks the engine is running. Do you have the Bentley service manual? I`m uploading the respective diagram here, just in case, I hope that`s allowed:




Hope that helps.

Hmm.. Looks like it got resized, I guess you can`t see the text. I can send it to you in the original size, that`s readable, lmk if you need it.

Got it.

I think I'm gonna try giving the crank angle sensor some voltage from the tach wire. I'm hoping that might trick the computer to think that the engine is running. I think that might cure what ails me.

If not I guess I've gotta wire stuff up.

Last image dump.. The body isn't gonna change much at this point so picture viewers can sign off now.

I have the "tuning top" on the car right now. It makes it soooooo much easier to make carb/timing or other tuning changes when the hatch isn't on the car.

OK sitrep I have cooling fans when the engine gets up to temp. The problem is the fans cool off the radiators... and the radiators are 2 meters from the sensor. Maybe some day in the future I'll wire up an electric water pump to turn on when the fans do. That way if I shut the car down the fans won't run FOREVER. ATM I wired them to turn off when key is in the off position.

There is NO power to the relay 2 box. I'm gonna try to hot wire the relay 2 box tomorrow. That might give me A/C voltage.

As for the tac... I'm still up in the air. I think I might honestly just get a Porsche CAS and glue a picup sensor to my flywheel. Kind of a jerry rig situation, but who cares.




Anyways, she is lookin suuuuuwweeeeeet. [You're supposed to read that with a good southern inflection]

















PS: yeah, I know that right fender is fubar... the door is questionable.

The propane diffuser fits.

Too much compression... too much boost... Too much timing... not enough ring gap... not enough fuel...

Muy muy mallo...




Its all good though. I sorta clocked myself working on the boxsterado this time. It took all of 4 hours to get from running engine to pistons out. Granted I am a "professional" mechanic, but even by my standards thats a pretty easy engine to work on.





The washer machine looks good though





Well lesson learned; I got some deep dish pistons on order and I said to hell with it and ordered some Eagle H beam rods. Cause why not.
