Hi guys.. Just a couple of quick questions...

On the front of the throttle body of the RB30 down under where the intake pipe joins there is a small pipe connection that's for the Idle air when the throttle butterfly is closed. Is that meant to have a hose hooked up to it or not? If so, where too?

And, is the AAC valve supposed to have a spring in it? I read somewhere to be careful when pulling it apart so as to not loose the spring, mine definitely did not have a spring.

And help greatly appreciated.

Don't mean to sound like a tard here but isn't it RB20, RB25 and RB26 only, or are you referring to a stoked RB26 or something.

no idea what this has to do with my questions...

I went and had a look at a mates and his has a hose coming off it but it just goes down by the engine mount so is still sucking in air.... i ended up blocking mine off till i figure out where its meant to go.

hey i dont know if im meant to post questions not relating to the one above me, but it says "rb30 questions" and this is one!

on my rb30 the fan is constantly running even with revs so i can never ever hear what the engine sounds like, just one big loud fan is what im driving right now! is there a problem with it? should i just install a thermo fan? or is that just how it is?? cheers if anyone could help me!!

Hey mate... here's a pic of the throttle body showing what I am talking about, thanks.

Oh and as for the aac valve, i got one off a mate and they do have a spring.

that pipe is for coolent to run through. to help the thottlebody warm up quicker or not freeze during winter... i think

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
