if I port and coat my exhaust manifold, o2 housing and 10.5 can I safely run 24 psi on 93oct without knocking?

in jan of 06 didnt you run 24 psi on 93 oct? on a dyno? I think you also said it was cause you ported and coated your exhaust manifold o2 and turbine?[

Ok, now we have MachV results of the previous 19psi chart vs our final 24psi chart, which included raised boost obviously and fine tuning for the intake and ported parts. Wow, 330/330 on pump gas without being tuned to the edge and hitting 24psi without knocking thanks to the ported mani/10.5 and Ebay o2 all courtesy of Dave Buschur. These parts are showing that they allow for more boost/timing on pump gas.

I did it for one run in preparation for tuning my alky in cool weather on a dyno, but it's not something I would have done for daily use. It's not a safe proposition, and it's not something that will be the same for every car.
that sucks! I was hoping of getting away of running 24 psi on pump gas..... safely!
