Intercooler Pipes Blow Off

Hey guys,

Just wondering, when your intercooler pipe comes off while giving it a bit....can it cause much damage to engine/turbo/anything??

mine came off this evening, and I have never experienced it, and as I am kind of new to turbo performance, I guess you could say Im a bit nervous incase there could be damage.

Morgs who was there, says these things happen! and are normally all good, just a time hassle to get it back on.

My car has only cat back, pod and a turbotech boost controller running 9psi - could this boost controller have caused the blow out? Say a spike somewhere?

Ive taken it off and put the stock part back on just for now.

Cheers guys,

Chris

Sounds like you either don't have a good enough rolled edge/retainer on the metal pipe or your clamps were either not tight enough or not up to the job.

When the exhaust is hot you could end up with a lot of flame out the exhaust like I did, melting the rear bumper, but you have to drive a little way for that anyway. Otherwise you could just clog up your plugs with carbon but no real damage will occur if you stop pretty soon after blowing the hose.

GTRgeoff - thanks for the reply mate!

Basically I pulled into the first side street as the engine shut down, no air getting in, stalled basically.

So fingers crossed its all good!

Cheers mate,

meh don't worry it happens all the time, will probably stall pretty quickly because afm is seeing heaps of air but very little gets to the engine.. the biggest pain is getting to the lower ones under the front bar.

Some fixes:

Bigger lip on the end of the cooler pipes

New cooler hoses, preferably silicon which don't baloon out under boost

Proper truck style clamps instead of those crappy screw type ones that Nissan gave us.

Yeh ive had the same thing happen about 4 or 5 times :D still have leaking problems to. Nissan clamps suck. None of the hoses justjap gave have come off but the nissan ones will need tightening using a spanner not a screwdriver. Also i noticed that my silicon hoses went softer pretty quick so after a week or 2 u might wana retighten. About 5 of mine were loose after the first week but now they seem ok.

well,

bit of a pickle again....

this evening, noticed he car was spooling louder and earlier

(I took the turbotech b/c off, so stock boost now) came onto main road, 1st gear, changed at 2.5k, into 2nd, went to bout 3-4k and the motor shut down again, spooled really loud this time.

Something must be up with one of the rubber joints yeah?

I cant see any splits, could be underneath where I cant see?

A friend thought maybe theres an electrical fault, i.e. a sensor is stuffed?

any ideas guys?

I can drive the car, but have to keep it off boost, which is likechanging at 1k revs!!

Not good

:blush:

hhhm.... thats odd, when i fitted my cooler yesertday i noticed that there is throttle lag when you drive normally but when you punch it you dont notice anything.

my car screams now from turbo spool and induction noise but i dont think its a bad thing.

although my car does now flutter heaps, sounds like wastegate flutter to me.

hmm...apparently everything seems fine.

My mechanic tookitfor a drive and said nothing went wrong, boosted well, couldnt get it to happen!

he even sprayed some carby cleaner over the pipes, gave the car a rev, and the carby cleaner didnt get sucked in, hence no leaks anywhere...but its still got a louder, higher pitched whistle than before.

really weird.

I wouldn't worry, i helped install a front mount on my mates supra and was boost at liek 18psi when one of the hoses blew off. The car stalled and the lights even went out :( but all was good jsut some P's and Q's on the side of teh raod at night trying to get the F#&$^er back on!

      Sadly I can confirm if you are actually seeking to drift, you will quite easily spin up one wheel. Even if you're going in a straight line. I am not entirely sure of the metrics/terminology here but there's only a certain amount that the helical will actually spin both wheels. I've seen it on video with my own car where two lines of smoke switch over to just one after you really get in to it. Unlike with a clutch diff where you can keep your foot planted until the car regains grip, in my experience with the helical you want to be utilizing traction control allowing LIMITED slip or lifting (partially) when you start to spin up both tyres with a Nissan helical. Which makes them pretty sub optimal for drifting duty. That said... this is probably a helical on numbers alone. Just put the Kazz in

      Let's just fix the problem by f**king the rest of the gearbox.

      Unlikely, as per Greg's post. This is not helical diff behaviour unless one wheel is up off the ground. Shimming what? You don't "shim" a mechanical LSD. Probably not in the sense that you have heard of people "shimming" a diff. And the process that Nissan f**kwits call "shimming" a diff involves super-preloading a VLSD cartridge against the side of the diff to create a friction/wear point (in a place that it wasn't supposed to have one) to make the sloppy, useless, viscous diff into a hybrid viscous/mech abortion. In case it isn't clear, I consider the process to be stupid. Nike.
