Hi All,

My cooler piping keeps on blowing off, and its great fun everytime cuz u get to pull over and get ur hands filthy putting it back on again, especially when its dark and ur on the side of the freeway with cars coming past at 100km/h almost swiping ur arse off while ur busy under the bonnet trying to the the pipes clamped up again!

Anyone know where i can get some hardcore hose clamps from? I got the standard hose clamps but since i started running some boost they always pop off. Had a look at autobarn and they didnt have shit ( i wasn't really expecting them to have what i needed anyway )

Cheers

Billy.

Do ur pipes have lips on the end of them?

If not, then i suggest it might be worth going to a welder and for them to weld little beads on the ends of ur pipe in order for the clamp not to slip off that easy.

Than again stronger clamps might do the trick too :)

Yeah those clamps look a lot more robust than the bodgy standard hose clamps i have at the moment. I tried a few hardware places and couldn't find any, i guess i'll check somewhere like ENZED and see if they stock them, i believe they deal just with hoses/connections etc. Does anyone know where i can get some of these in melbourne?

Thanks

and get some silicon hoses at the same time.

BTW, I was never too worried about a cooler pipe popping off....until I saw Skylinegeoff's car catch fire due to the amount of fuel coming out a hot exhaust...check out his avatar!

How does a cooler pipe popping off make your car catch fire ? it dosn't have anything to do with the flames comming out the exhaust ?

Well....say the turbo is sucking 1 bar of boosted air (+the regular 1 bar air) thru the AFM, and blowing it out the open cooler pipe. Then the cooler inlet pipe sucks in the regular 1 bar air.

The ECU sees 2 bar of air coming into the engine even though only 1 bar actually makes it. It then puts in at least twice as much fuel as it needs.

As a result the engine runs (if it runs at all) super rich....heaps of fuel gets dumped down hot exhaust. In this case, the exhaust was hot enough to light the fuel in a 2 foot flame :D

Lucky he had a fire extinguisher in the car or it would have been pretty ugly.

Ok,

My thoughts were if your running an AFM meter and you blow a cooler pipe, the turbo will still be pumping 1bar, but the open cooler pipe will be trying to suck in standard air atmosphere pressure which will make your car to, pretty much stall instantly. The flame will be caused by the low amount of air intake in the cylinders, leaving excess fuel to hit the hot turbo and ignite. I don't think it would make the ecu put twice as much fuel as your car would be off by then..

I get mine similar to SK's pix from Purple Pig in McIntyre Rd Sunshine I think - about $8 each.

Also I have put three equally spaced dimples in the end of the pipes about a centimetre in from end with center punch from the inside to give the hoses something to be gripped by the clamps.

      I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly.

      Can you mount the ATTESA pump in other locations?

      That worked out PERFECTLY! Thank you big time to JJ. He was able to swap me his stock diff. He drove all the way to me as well. Killer! Removal & install was pretty straightforward. The diff itself is HEAVY. So that’s a 2 man job.  Man does the car drive nice now! Couldn’t have worked out any better 👌
