What's Ideal 13B NA (6-Port) Port Timing?
Hey guys/gals,
I've looked through several threads (Highest Power Challenge: 2-rotor Non Bridge Non Peri, for example) trying to find some concrete information regarding port timing in terms of increase in performance for the 6-port NA 13Bs, but found nothing.
I realize what I'm asking for may be 'proprietary' information, but I would appreciate any help; if not actual port timing, just an idea of the differences in timing from stock to street port (and the difference between different 'brands' of street ports). Or at the very minimum, information on the best street port available. My ultimate goal is to build up a 6-port S4 13B, and create my own porting templates using the complete 13B model I have drawn up in CAD.
The car is a GSL-SE that will eventually be running a Megasquirt, will be used for daily driving and weekend lapping days. Power goal is 200hp.
Thanks.

Thanks for the help.
I'd like to keep everything I learn out in the open so I can share results with other users. If you don't mind posting up some numbers here, I would really appreciate it.

Unfortunately I don't have a screen shot and I only have timing figured out and so far only for the S4. I still have worked out the S5 yet. You are on your own for fuel maps though. What I can do is to just write it out by hand on a piece of paper, scan it and post it. That would probably be easiest.

its also important to remember that the port is only as good as the rest of the systems, intake exhaust etc. i like the gsl-se intake, as it gives a really broad power curve, but 200hp with any port is probably impossible
