Look at the page of AMG, you can read 0.8 bar = 11.6 psi

With Cams and long tubes, I would suggest you are pretty close to what you should be. It's not about boost. Its about CFM. Boost is a realitive pressure measure for a given volume. Horsepower is made by increased CFM of air into the combustion chamber.

I run a 185 and similar mods, and I see 13.5 in 3rd. Do you have a boost reading of when you "feel" your car was faster?

I would be concerned about not having at least injectors to add fueling. Especially if you are doing prolonged high speed full throttle runs. These motors have blown on stock boost under those conditions with cold air. Maybe it feels slower cause you are down on power due to hurting the motor/low compression?

Also, the 3.06 has nothing to do with this. It will actually make for stronger top end in sacrifice of absolute top speed.

Only advice I would give is to make sure the supercharger belt is VERY tight (go smaller belt). I have a nicely milled SC pulley and regular belt tightness (like it felt stock) it would slip like crazy. I kept buying smaller belts until I could barely get it on the car even with tensioner cranked back. Now she works juuuuust fine.

There is concern around supercharger snout with belt that tight all the time but with a few thousand miles on it...it is just fine.

If that's using a narrowband sensor than the value is useless since narrowband sensors read only accurately at 1 lambda or near 1...if it's a wideband sensor then .85 lambda is 12.5:1 A/F ratio which is pretty lean for pump gas.

HIghest I saw on OEM was 11.6 but with longtubes highest I've seen is about 10.5. The catch is I've never seen max boost till I'm in third gear.
