Problem is cylinder pressure and low octane fuel. Is no way to compress 89 like that without spontaneous combustion, especially in a hot engine. I shot spark sooner to control explosion, but it killed performance. Note you can actually have multiple explosions within single stroke -- that's why flame control important. Situation made worse by fuel enrichment disabled at SEDOC. Drove down with car tuned for nipple attached correctly (Martin's right on that one -- 038 series CPR totally different from 066. Even the Swedes agree). Was told (incorrectly) by someone there who rebuilds these things the nipple was actually a vent and I would end up sucking raw fuel into engine, so I unplugged before trip home (capped off vacuum port). But CO2 screw never adjusted to compensate (vacuum on 038 series affects counter pressure at idle as well as acceleration drop). Final nail in coffin was vacuum leak at HVAC mode switch. Needless to say was not a happy trip home. Absolutely melted plugs on driver's side of engine (vacuum leak from HVAC switch, which taps into passenger intake rail). Passenger side were hot but survived. THAT'S when I did compression test (wanted to ensure no valve damage), got high readings -- equal the whole way 'round, thank you very much -- and realized something dramatically wrong with my block vs published domestic PRV specs. Started researching Douvrin. Until then had never even heard of a high compression PRV (have you ever heard another DeLo owner mention one?). As soon as I realized little silver car in same league, more or less, as two tone Lincoln was simple fix to tune to high compression specs. THAT'S why I brought R42's as spare plugs rather than R44's. Didn't know really how hot HR9's were -- insulator *IS* longer than R42 and electrode is just a little dot -- but found out very quickly. Water temp was the giveaway. Decided to pull a couple in Fayetteville before getting on I-95 and found them white. Swapped for R42's in a parking lot. Not a bit of trouble since. Speaking of little silver car and two tone Lincoln: are currently parked side by side in driveway (ultimately decided to drive truck today). Front bumpers lined up. Lincoln driver seat back in line with U pipes. THAT's a car.
