i think my intake valves are working ok now.
quick short run in second gear:
rpm 7410
injector duty cycle 91.4
STFT minus 0.16
Load 163.07
ltft minus 2.5
Maf 318.76
IAT 91.4
Throttle position 65.91 ( i need a heavier foot)
lead ignition timing 13.5
yes the air flow was smooth and linear .
I wish I knew how to get the data into a graph form.
The numbers do not represent the performance in my opinion
looking at the graph it took me 1.05 secs to go from 41.01 mph to 55.92 mph in 2nd gear ( 09 trans with 04 diff--oem size tires).

at the risk of fueling the flames of supercharger fanboi hatred, the cons are that small displacement, high rpm engines and superchargers do not a good couple make. First, the supposed lowend boost of an SC setup is totally false, it is just the opposite with today's turbo technology. Second, for the same engine stress level that you make an extra 70 HP on a Renesis with an SC equates to about an extra 110 HP with a turbo setup because of the power drain required to spin the SC at high speed. Further, with a high rpm engine then the higher you spin the engine the more power eaten up by the SC and in turn the more stress load that is placed on the engine for any given power increase at the rear wheels. The higher stress load is not just on the engine, but also all the supporting equipment such as radiator, oil coolers, exhaust sizing etc. They are also a lot harder to keep quiet since there is nothing damping the sound level coming directly out of the engine unimpeded into a high flow exhaust system.
The pro is that you can't just turn up the boost at the twist of a ****, which is where most turbo owners discover their destiny to fail.

Nothing much has changed since you were here last - but check out the Turblown top mount thread . IMO the best solution has always and will always be to by a used Greddy kit off some idiot who f'd up their install and do it properly the 2nd time around.

funny, shipping parts cheap to nz. kinda pays off..
seems i have been gone semi long time, tubo kinda plug and play does not exist. guessing pettit might still be making stuff.
my ms3 is going away soon.. my rx8 has just been sitting under a car cover.. WAITING!
hymee?
tell you what i would like.. stuff a 09 tranny in my car. with something that makes about 325hp to the wheel.
how hard is that. btw, i missed my first friday before the rolex sports car race in 9 years..
weather. everyone at the 24, enjoy!!

just installed a new front o2 sensor. My old one was just old--seemed to be functioning well, tuner tuned with it and said it was fine, BUT after the install my closed running was different. Warm up transition is smoother, recovery from decel is MUCH better ( like oem everytime), just seems to be more responsive in closed loop. I hate subjective "findings" but there was a noticeable difference that I cant prove. Anyway--just posting just in case anyone ever wondered..
