hey hey, i had a pfc boost controller hooked up in my old car but when i sold it i didnt remove all the parts for it. i have the thing that you plug the lines into but not the solenoid i think it is.

i'll get some pics of what i have in the morning, but i wanted to know is it possible to buy just that part that im missing or am i up for a whole new set?

also while ive got you here, my car was running fine untill a couple of days ago when i started to get heaps of knock, like jumping into the 90's at times. its fine if im just driving around normally but as soon as i give it a hit i get heaps of knocking. i thought maybe bad fuel but if refilled the tank since and same thing happening. nothing has changed in the car at all and ive had to wind down the boost to try stop some of the kock, was running 15psi and wound it back to 12ish. whats the go with that? spark plugs?

anyway thanks for reading my longest post ever :laugh:

fiddlying around with the thing today, and i took it out with no air filter at all on it and knock was basically gone, only went to around 20. then i put my old pod on which is less restrictive and i had heaps less knock than with the apexi one ive got.

is it possible that the rubber tube running from the afm to the turbo is sucking shut, more so when i have a more restrictive intake? would this cause more kock?

when you took it out with no filter did you turn the boost back up to 15psi ?

the intake pipes standard have been known to suck in its a common problem

i wouldnt run 15psi on a standard turbo either. but whats making me think maybe thats whats happening is the more restrictive the air filter is the more kock im getting, and i saw in the pod vs airbox thread that with the airbox being more restrictive it was sucking the pipe closed.

well the car has been sitting in the drive way since april due to an unexpected trip to court (apparently speeding deserves more of a penalty than drink driving, stupid f**kers seriously but anyway) and i been thinking about the pinging how it just started happening.

maybe fuel filter is getting clogged? would that do it? or would that just make the fuel pump work harder.

      Car Rotisserie

      By Shoota_77 · Posted

      Hi guys, has anyone either purchased or built themselves a rotisserie for their car before? I can only just justify the need for one hence why I should just make one but at the same time, if I make one I can kiss another 4 weeks of potentially productive car working time goodbye because I'm building a bloody rotisserie....  I mainly want it for the application of the body deadener.  Cleaning the old stuff off, priming and then colour over the deadener doesn't worry me, it's just the application using the Schutz Gun that I feel would achieve a significantly better finish painting it side on and keeping the Schutz Gun upright.  I don't think they would work well on the side let alone almost upside down for some areas.  If the product I use (Terosun, etc) could work through a HVLP ok then it might be ok to apply without the rotisserie.   I can get one of these style ones for about $1200 which is pretty good value-     I reckon if I made one it would cost around $500 but it's more the time that it would take is more of a killer than the cost.  They look to hold their value pretty well second hand so I could always sell it after using it and realistically only lose $200-$300 at worst.  Or keep it and buy another project when this one finally sees the light of day... Anyone selling one...? Cheers!

      Stock rb25det neo questions

      By GTSBoy · Posted

      While it is a very nice idea to put card style AFMs into the charge pipe (post intercooler, obviously), the position of the AFM and the recirc valve relative to each other starts to become something that you really have to consider. The situation: The stock AFM is located upstream the turbo, and the recirc valve return is located between the AFM and the turbo inlet, aimed at the turbo inlet, so that it flows away from and not through the AFM. Thus, once metered air is not metered again, neither flowing forwards, or backwards, when vented out of the charge pipe. When you put the AFM between the turbo outlet and the TB, there is a volume of pressurised charge pipe upstream of the AFM and there is a volume of pressurised pipe downstream of the AFM. When the recirc valve opens and vents the charge pipe, air is going to flow from both ends of the charge pipe towards the recirc valve. If the recirc valve is in the stock location, then the section between it and the TB doesn't really matter here - you're not going to try to put the AFM in that piece of pipe. But the AFM will likely be somewhere between the intercooler and the recirc valve, So the entire charge pipe volume from that position (upstream of the AFM, back through the intercooler, to the turbo outlet) is going to flow through the AFM, get registered as combustion air, cause the ECU to fuel for it, but get dumped out of the recirc valve and you will end up with a typical BOV related rich spike. So ideally you want to put the AFM as close to the TB as possible (so, just upstream of the crossover pipe, assuming that the stock crossover is still in use, or, just before the TB if an FFP is being used) and locate the recirc valve at the turbo outlet. Recirc valve at the turbo outlet is the new normal for things like EFRs anyway. In the even of a recirc valve opening dumping all the air in the charge pipe, pretty much all of it is going to go backwards, from the TB to the recirc valve near the turbo outlet. But only a small portion of it (that between the TB and the AFM) will pass through the AFM, and it will pass through going backwards. The card style AFMs are somewhat more immune to reading flow that passes through them in reverse than older AFMs are, so you should absolutely minimise the rich pulse behaviour associated with the unavoidable outcome of having both a recirc valve and an AFM in the charge pipe.

      Yep, in my case as soon as I started hearing weird noises I backed off the tension until it sounded normal again. Delicate balance between enough tension to avoid that cold start slip and too much damaging things.

      I'm almost at a point where I feel like changing the alternator. Need to check the stuff you mentioned first though.
