Pettit Super Charger Owners
Not to mention produce way less power, even if it didn't detonate.
12.3:1 or so is the leanest point for power on the Renesis.
11.5:1 is as high as I would go with any serious boost.
I stay below 11.1:1.
BTW - how much boost is represented in that plot? ~260 HP and ~180 tq would equal about 4 PSI on my turbo.

It's a rough comparison, one that is dependent of exactly where it is being measured, but when speaking generally the needed A/F ratios are pretty consistent. The real deal is looking at mass air flow.
Are you the only one that realized in this particular instance, I was talking about the carpet? This was in response to you and Brettus talking about it. That's why it was right under your post and not under Jeff's request for a dyno from somebody with a Pettit SC. Maybe, it's late, but I don't think everyone got that???????

I saw as low as upper 10's when NA while WOT.
Is there a way to estimate the amount of air this SC pushes at 7-8 psi, and calculate based from the increased air, what the AFR would be if the PCM wasn't adding additional fuel?
