Car would have put down a little more but turns out the pressure tube from the airpump feeding the rpm switch blew of at ~7500 rpm on the first run slamming the ports closed, The second run I unplugged the switch without knowing this to get a baseline with the 6-ports closed, the third run shoula have been another full power run but the the hose was still off, i thought i broke the rpm switch by unplugging it with the car on, and didnt discover the blown off pressure line until i got home.
relevent mods:
RB header
straight pipe to stock Y to "seven stock seven RB bargin bin" mufflers
Fc100 ignition
cone filter
electronic 6-port actuation
ported/port matched intake manifolds
aux bridge motor

thanks :-)
S5 rotors
Gonna have to wait for another dyno day to dyno her again, im working on alot of stuff for her too in the mean time, new exhaust, a megasquirt, a custoom intake manifold.
I scanned tracings of the ports a long time ago, pretty early int he porting process tho, before the bridges were added,.. they should eb in the porting section.
The port timmings tho are:
primary:
intake open: stock (32 atdc i think)
Close: 62 atdc
secondary:
Intake open: stock with closed aux ports, 45 btdc with them open
Intake close: ~82 atdc (stock with a minor beval)
Exhaust:
open: 80 bbdc
close 65 atdc

Smooth.
It can have a slight lope sometimes when its cold.
I had an aux port stick open on me once, it brapped all the way home
would almost die at idle so i had to keep my foot on the gas a little, but i felt like a badass with it brapping away.

Not yet, but ask me in 10 years :-)
There is a ton of room to keep the bridges thick vertically, so even a very thin bridge should be reasonably reliable.
I was a tiny bit worried about how thin the support for the o-ring is, but i tried to get that inline with the thinnest area of support on a stock plate, so it should be ok.
