On the dyno at around 5800rpm my car kicked out 3 puffs of grey/black smoke and the power fell off hard. No noise (typical det) from the motor (marbels rolling around) and the motor is still in one piece.
It was like puff..puff...puff small pause in between.
This was around 20psi, so I'm thinking the motor def woulda been hurt or heard some unhappy noise from the motor if this was detonation. My tuner is dead set on detonation because he can see detonation from the exh (new to me) but I think it was spark blow-out.
I was on Auto-lite 3923s (2 ranged colder than stock) gapped @ .035. This was around 550rw with (total timing) 14*@4k, 12*@5k, and 10*@6k on a 9.82 or so a/f no methanol. This was only on 91 octane (yeah I know) but in order to tune for methanol you have to get the car somewhat tuned in on pump gas.
Need some help.
I plan to take some boost out of it, bring my gap down to .026, and possibly try a colder plug. I am done messing with methanol and have 10 gallons of 109 Sunoco GT plus waiting to go in
Any input
