hey

the other day i made a phone call to CES (Custom exhaust systems) and they told me that an R33 gtst skyline has stock 143kw at the wheels. they than told me that they have an exhaust system worth, $1900 that will give the car dyno proven 180 to 188kw at the wheels, and after that installing a kn or decent air filter, and turning up the boost to around 11 or 12 they can produce up too 200rkw, do u think this is true, because they say they have dyno proven results and if it is than the car would have to be pushing high to medium 13 second times, wouldnt u think? can someone shead some light on this topic becasue im sure if its true than alot of poeple will want their exhaust.

didn't think just adding an exhaust to a car would give that much of an increase in power?

i thought you would need zorst, air filter, boost and tune to get near the 180rwkw figure, everyone that i know (including me) who has the above mentioned mods (note stock dump pipe) are getting around the 175rwkw on 11-12psi.

hey i wouldnt normally, but the exhaust comes with ceramic twin dump pipes, and they r the only copmany in qld that does proper mandrel bends, also i rang another exhaust shop(Lees exhausts) and they cant even do what (CES) can do and reccomended them to me. so if its true and would give such a power increase than it would be money well spent.

Not that this has much reference to you..but, i put an exhaust system on my GTR, power went up 25KW's at all four wheels with nothing else changed. Came at a cost though. TRUST cat back was $1200 and HKS front pipes were almost $900. From what i've seen at several dyno days, R33 GTST's with about 13-14psi, full exhaust, air filter run about 180kw's at the wheels. Every single dyno is different but around 180rwkw seems to be about the normal figure.

Jono

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked... HTH
    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
