OK, after geting my new nose for my SC and a custom air intake fabbed up I noticed a meager dif in performance.
So, I made it a point to run up and get Dyno'd again to make sure my air/fuel was ok(being, giving the engine is getting a hellva lot more air) and what not.
To my surprise and the good guys at Dynocomp (www.dynocomp.com) the difference was uncanny! As you can tell from the chart, I added about 50ftlb of tourque and 50hp off the line....da...ham!
The dotted lines shows my new run, the solid is my old with the stock airbox.
The air/fuel was right on the money(what I was most worried about).....strange thing though, I'm still at 4psi boost. I am certain now that I'm running with a 5psi pulley, when I got the new nose for the SC they sent it with a 4psi pulley to compare....there is a diff between the two, the 5psi is about 1/4 inch smaller.....baffled.
Oh, so I suggest....if your running a SC with a stock airbox, look up, the proof is in the pudding.
