Well, sounds like this engine met an unfortunate ending. Duane reported tipping into the throttle at 75 in 6th, and it blew out a giant cloud of white smoke. Dip stick was pushed out. Compression is 160, 155, 0, 175. We're thinking the previous tune did some irreparable damage, and despite my efforts to correct them, it had experienced too much detonation.
Here's the dyno graph from the dyno, on the first run, you can see I gave up after 5,500 as the rich 10:1 (or more) was cutting out the spark.
Finally ended with a tune that was still fairly rich, but was running low 11s. Owner was discussing adding a square top and catless downpipe, so I didn't go too aggressive. Timing was 16-18 degrees in boost, only 15 by red line.
I'm also attaching the .msq and datalog of the above dyno run to see if y'all see anything that might of indicated an issue.
I have a built shortblock in stock that would solve that problem. Mail me that one and a check for ~$3k+ship and I'll mail you mine. I can even put an MSM pan on it if you want (there's no pan/pump on it right now, just a rotating assembly).
That's probably exactly what I would do Savington, however I'm not sure the owner has that money right now. He has offered the car for sale at $8k, and I really wish I had $8k laying around to take him up on that offer.
6uls/11.75 brakes/BBFW bar/mspro/FM intake/FM intercooler/FM downpipe/FM exhaust and other things would pay for that.
