A REAL SC14 BOOST LEVEL

Hi,
4AGZE uses SC12, 1200cc/rev
1GGZE uses SC14, 1420cc/rev
All AW11s I have ever seen (read LOTS) run about 8psi stock, unless their supercharger is stuffed or the belt is completely stuffed or loose, on there is leak in the inlet system.
My opinion is that while anything is possible, don't push an SC12 past about 14psi as I have seen atleast two with stuffed rotor coatings from hard use at this overdrive ratio. A Stock 'ZE AFM ECU with kill your engine above 14psi by leaning _right_ out due to (I hypothesize) thinking the AFM output must be bullocks!
My 4AGZE now, running a Suby intercooler, 168mm crank, 120mm levin SC12 pulley which I transplanted onto the SC14 makes just over 18psi from about 3000rpm up, there is about 12psi avaliable from 2000rpm. I _think_ there is about 1.5psi gained from my less restrictive inlet system (70mm pipe, bigger IC, 60mm throttle)
My current overdrive ratio (which I use now with an SC14), when used with the SC12 on my unmodified otherwise stock AW11-GZE engine gave 11.5 PSI pressure at the manifold, which is still a nice improvement over stock.
Cheers, Nick
