Hey Guys, as above, Can i run a blow off valve setup off the hot side of the cooler setup on a 26 rather than the cold side. Installed a 26 in my R33 Gtst, and am having problems with the bov return pipes.

Would make life easier if i could run BOV's on the hot side and get them plumbed in there too..

Whats your Say on this guys?

Cheers

I was running a vented BOV on the hot side, right infront of the turbo actually. I took it off the same day I fitted it on, mainly because I hate vented BOV's. It worked just fine. Plumbing back a BOV back onto the hot side hmmm kind of sounds weird to me but that would be very interesting...

I dont see why not. Its doing the same job regardless.

Just seems like most BOV are as close to the TB as possible.

I have seen a GTR with custom bov return. They just made a pretty stainless pipe up that went between the head and the radiator. Looked good. Cant seem to find the picture anywhere though

In short: "I installed a bov and then I took it off on the same day, because I hate bov's"

Some people have weird ways of passing time..

OP, you can run it on the hot side its fine. In theory the closer it is to the throttle the better but I've never had a problem with it on the hot side and many brand name parts come in a kit on the hot side. Whatever really..

Just had this debate. I reckon nearer the turbo rather than nearer the throttle body but where ever it is I suspect makes very little difference. Some people have it on the hot side some on the cold side some manufacturers stick it on the intercooler so what ever suits your needs or tastes will be fine.

This one?

Some guy gave it to me, it came welded onto the standard hot pipe to be a direct replacement into the R33. He said they don't sound like the other high pitch BOV's. I tried it out, didn't like it, sold it lol. Turbosmart, turbofart.

Was it the 'rattle snake' one? I like that one better than most but still not a fan of atmo's.

In my case it's stock GTR or nothing.

Its taken me a while to get what you're saying but I don't think (hope not) that the OP is planning to plumb the bov back into the hot intercooler pipe but into the turbo intake on that side of the engine!

It would work but maybe not as well as just before the throttle body, may get a bit of reversion.

When I went forward facing plenum in my 32gtst (custom setup, not GReddy so didn't go through the battery tray), I fitted a full 32GTR cooler/piping/bov/recirc setup. Really nice solution!

With the 34 I will do the same but just run 2" pipe straight across instead of the molded plastic GTR recirc pipe :thumbsup:

    • I came here to note that is a zener diode too base on the info there. Based on that, I'd also be suspicious that replacing it, and it's likely to do the same. A lot of use cases will see it used as either voltage protection, or to create a cheap but relatively stable fixed voltage supply. That would mean it has seen more voltage than it should, and has gone into voltage melt down. If there is something else in the circuit dumping out higher than it should voltages, that needs to be found too. It's quite likely they're trying to use the Zener to limit the voltage that is hitting through to the transistor beside it, so what ever goes to the zener is likely a signal, and they're using the transistor in that circuit to amplify it. Especially as it seems they've also got a capacitor across the zener. Looks like there is meant to be something "noisy" to that zener, and what ever it was, had a melt down. Looking at that picture, it also looks like there's some solder joints that really need redoing, and it might be worth having the whole board properly inspected.  Unfortunately, without being able to stick a multimeter on it, and start tracing it all out, I'm pretty much at a loss now to help. I don't even believe I have a climate control board from an R33 around here to pull apart and see if any of the circuit appears similar to give some ideas.
    • Nah - but you won't find anything on dismantling the seats in any such thing anyway.
    • Could be. Could also be that they sit around broken more. To be fair, you almost never see one driving around. I see more R chassis GTRs than the Renault ones.
    • Yeah. Nah. This is why I said My bold for my double emphasis. We're not talking about cars tuned to the edge of det here. We're talking about normal cars. Flame propagation speed and the amount of energy required to ignite the fuel are not significant factors when running at 1500-4000 rpm, and medium to light loads, like nearly every car on the road (except twin cab utes which are driven at 6k and 100% load all the time). There is no shortage of ignition energy available in any petrol engine. If there was, we'd all be in deep shit. The calorific value, on a volume basis, is significantly different, between 98 and 91, and that turns up immediately in consumption numbers. You can see the signal easily if you control for the other variables well enough, and/or collect enough stats. As to not seeing any benefit - we had a couple of EF and EL Falcons in the company fleet back in the late 90s and early 2000s. The EEC IV ECU in those things was particularly good at adding in timing as soon as knock headroom improved, which typically came from putting in some 95 or 98. The responsiveness and power improved noticeably, and the fuel consumption dropped considerably, just from going to 95. Less delta from there to 98 - almost not noticeable, compared to the big differences seen between 91 and 95. Way back in the day, when supermarkets first started selling fuel from their own stations, I did thousands of km in FNQ in a small Toyota. I can't remember if it was a Starlet or an early Yaris. Anyway - the supermarket servos were bringing in cheap fuel from Indonesia, and the other servos were still using locally refined gear. The fuel consumption was typically at least 5%, often as much as 8% worse on the Indo shit, presumably because they had a lot more oxygenated component in the brew, and were probably barely meeting the octane spec. Around the same time or maybe a bit later (like 25 years ago), I could tell the difference between Shell 98 and BP 98, and typically preferred to only use Shell then because the Skyline ran so much better on it. Years later I found the realtionship between them had swapped, as a consequence of yet more refinery closures. So I've only used BP 98 since. Although, I must say that I could not fault the odd tank of United 98 that I've run. It's probably the same stuff. It is also very important to remember that these findings are often dependent on region. With most of the refineries in Oz now dead, there's less variability in local stuff, and he majority of our fuels are not even refined here any more anyway. It probably depends more on which SE Asian refinery is currently cheapest to operate.
    • You don't have an R34 service manual for the body do you? Have found plenty for the engine and drivetrain but nothing else
