This may be a really stupid question but I am looking at getting a blow off valve for my r33, i know there are a few different sounds that i have heard a blow off valve produce and was just wondering if most commercial BOV's make the basic sound or not? How do u know what they sound like. I like the sound of the ones they generally use in a rally. no idea how to describe that.

that would be the closest to a rally car noise you will get, but remember puttng a to atomospher blow off valve will f**k your tune and the car will not run right (it will stall and carry on at low rpm) Rally cars shoot a bit of fuel directly into the exhaust wheel (after burn to keep the turbo spooled up at all times) after they back off and change gears.

i have the same one, only problem I have ever found was, half way through a race (drag strip) I had no boost, bov stuck open. Also after a while you cant adjust the level of noise that comes out via the ring, you can only have loud

    • Dort sounds above 3k rpm are dorty 🤣 I might krinkle black the alloy 🤔
    • It makes you wonder, all these people starting to make a billet replacement head, I wonder if any have thought about trying to adapt tech from newer engines into them. You're already at the full design stage to make a billet head... Why not really spice it up and had some more modern tech into the mix too...
    • Connect all the plumbing up properly. The actual worst part about having the turbo unable to actually build boost, is you can and likely would over soon the turbo if you drove the car (free rev while stationary isnt likely to manage it).   If you do have an air leak as Duncan suggested, you'll have a bad time as the AFM will be saying different to reality.   As you have had the engine out, I'd go over all electrical connections again. If you have a consult cable, plug it in, and see what the ECU thinks is going on. Did you touch the timing belt? If so, double check your timing on the gears is correct AND put a timing light on it while it's idling and see what ignition setting you have. Is the AFM you've installed the one that was in the car previously? You said you replaced seals, what seals exactly? What have you had apart?   From memory when I had my RB25DET with factory throttle, there was two plugs the TPS plug on the loom could go to. One would leave the car running like shit, the other made it work, I think one plug on the TPS area was for something else (an option). It's too many years since I saw that part of the loom to remember properly though.   Is the car idling smooth (as smooth as an RB can)? Does it smell fuelled up?   I have a feeling either timing in timing belt is off, or a sensor isn't right.
    • Theres still skid pan and motokhana days up in QLD at least that are $100 or less. The ones that are ran as "driver training" less so, they're expensive, but just normal skid pan days like SAU ran are still low cost. And thats one of the places I learned to be a lariken, purely by asking for passenger rides, and how people were doing crazy things. Reese gave me plenty of pointers back in the day for skid pan! And yes Duncan, I will never forget your pointers for track work. Especially after Neil got out saying "I am NEVER getting in the car with him again!" 😛
    • 49719 is the cooler loop. Right at the front, LHS of that diagram. Return line from rack (LP side) goes to cooler loop on RHS front of car, then back under engine and returns to bottom of tank. 49717M is feed from tank to pump. HP line out of pump is thick rubber, followed by the hard line that runs down to crossmember and runs in parallel (but opposite flow direction) to the LP return line. Nothing goes anywhere near the firewall or interior of car. The closest they get to that is the connections on the rack.
