Ignition retard knock sensor.

[Bruce Plecan]

I'd get an EGT, and Oil Temp guage on that, right away.
I'd get Corky Bell's and Hugh Mc Innes books on turbos in short order, also.

| Compression is 8.6:1  Timing is 12 deg BTDC.  And no, the engine
| to my knowledge isn't actually designed for a turbo, although a
| smaller version (.3l smaller) used in cars was (that's where the
| turbo and exhaust manifold came from).  Also, the factory shop
| manual does say something about it cooling the underside of the
| pistons with oil like some turbo engines do.  It doesn't actually
| say it has an oil jet spraying the backside though.  OK, I just
| checked the wording again.  It says "An oil jet on the connecting
| rod provides lubrication to the backside of the piston."  Would
| that be a cooling spray or is it just to lubricate the wrist pin?
|
| Also, my cooling system is pretty good I think.  I had overheating
| problems during extended crawling around the desert in the summer.
| I upgraded the stock, single row radiator (about 1/2" thick) to a
| much larger capacity 3 row core (about 2" thick) when I put the
| turbo on so I think I have some breathing room there.  Does that
| really make a difference for extended boost?
|
| 9 psi on regular?  Is that too much to ask?  Sounds like it eh?
| I don't typically drive a lot loaded down through the hills.  Maybe
| a half dozen times a year on various trips which I can use higher
| octane gas for.  I just hate having to pay for it all the time
| when I actually only need it about 1% of the time.  Hence the
| thought of an ignition retarding knock sensor for that 1%.  Also,
| I've gotten quite good at driving it an avoiding detonation.  I'd
| hate the thought of letting (or needing to let) someone else
| drive it.
