yeah the cops just pic a car they wont and see if they can find anything wrong with it. i no when i had my GSR lancer with evo3 kit on it i used to get pulled over all the time cause it stood out and in my skyline i havent been pulled over yet and i drive that alot harder. I reckon its cause it looks stock no bodykit only mags.

hmmm. i got pulled over at a "defect" set up on clarence street i think it was in belerieve.

ive got a r31 rb30e+t, the car was wearing bald front tires at the time (got three punctures in my good ones so chucked some spares on :laugh:) car has a woodstock "catch" can.

they pulled me over, checked my back tires, didnt check under the hood (i had a dash mounted boost gauge so i thought they might have put the puzzle together) and then gave me a defect notice for having a headlight out, just the headlight not the parker, didnt check my front tires or anything else at all.

replaced the headlight, wiring was screwed so i twisted the parker wire together to the headlight wire and bing! no more defect... altough im sure its now heaops dodgier than having 3 lights at the front of your car insted of 4... they only gave me 72 hours to fix my headlight wiring :D

i have noticed quite often lately ive been pulled over alot, i dont mind tho, id like to think that if my car was stolen a cop would pull the crim over thinking it was me (hoon) and licence+bretho check so i could use that licence number they got to find who pinched ma car!!

as for your run in with the bov atmo being illegal, should have asked what legislation that reffers to and also what the lmax legal DB reading is and how they were measuring it, sure they would have done you over but its not liek they could have gotten you for hooning if your parked?? lol

is a trucks atmo bov illegal?? what about there hydro brakes when they pull up at the lights?? its basically the same sound

Edited by Cheddle

oh. cool :laugh: there ya go air brakes... once had one of my mums friends ask when i took her for a spin in the gts-4 "wha?? does this think have those hydralic brakes them trucks have??" so thats as far as my education on brakes on trucks goes :D

Trucks dont run blow off valves, they dont have throttle plates or even vacuum for that matter. Engine speed all controlled by fuel delivery...

so how does the air get into the cylinders in N/A trucks? vacuum generated by the pistons moving of course

the truck i drive is a v8 turbo diesel and that has got a wastegate on it and thats fairly loud. get pulled over all the time from transport in it. they pull all company trucks now trying to find anything wrong with them, even when they are brand new idiots.

Of course its got a wastegate, its not going to just freeboost is it.

I'm glad they pull trucks all the time. They're pretty f**king dangerous things to drivers and other motorists when not in tip top mechanical nick.

Yes there is vacuum generated on the intake stroke only, but there is no manifold vacuum since there is no throttle. Hence the reason for the use of vaccum pumps on smaller diesels with vacuum assisted brakes.

and how often does the intake stroke occur?

and the only reason for the vacuum pumps is becuase the vacuum that is generated by the engine isn't enough to run brakes powerful enough to stop the truck/

Most trucks use air operated brakes, climb back in your hole wombat.

I was making a point that trucks dont use blow off valves because they dont have a throttle plate, what happens when you open the throttle completely on an aspirated engine?? Manifold vacuum disappears.

Thanks for the education though, ill keep it all in mind. As Wogboy said, once you create a restriction the vacuum is huge.

Getting back on topic now....

Yeah good idea, I'm not sure about anyone else up here in Northwest tas but I haven't any trouble with cops pulling me up for my car and my gtr runs sequential bovs and they ain't exactlly queit but then neither is my car. Which wogboy can confirm

    • 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.
    • @Dose Pipe Sutututu I read your replies RE: R35 GTR MAFs, any ideal spots to put on? Obviously will need the adapter plate. Will be having a cross over intercooler fitted shortly, would putting it a bit before the TB be okay?
