Here's a short story:

Just took the skyline for a quick spin to try a new fuel map.

When there was no traffic I floored the pedal a bit more (about 4000rpm) ...

The car started to move forward and came on boost - suddenly - BANG!

Yes! BANG!

:wacko::unsure:

OMG! (It was a very loud BANG!!!)

What had I done?? (my fuel map wasn't that bad, was it????)

I rolled (engine died off) to the left and opened the bonnet, but I could see no damage ..

So I started the engine again (and secretly hoping that everything would be fine)

, but it ran very, very poorly.

Also I could barely keep the revvs over 3000rpm and the engine would die off often.

The car made a lot of black smoke and noise either ...

A nightmare!

In 3rd gear and with a lot of smoke and sweat I made it somehow home.

(I was just 3km away anyhow)

With a flash-light I checked under the car and could find no oil leakage or obvious damage.

Again I opened the bonnet and there it was ->

The newly fitted hose joiner had come off .. :)

PHEEEWWWW! Seems it is my lucky day!

(Thanks for listening)

Ohhh ... I see what you mean!

Thanks!!

Given where the clamps are on the hose, and how long the pipe/lip is - doesn't look like it was done up correctly.

Make sure you get the clamp behind the lip this time around.

:)

It was my first time ;), and I just recently fitted a new turbo ..

So I really thought something massively wrong has happened :)

Obviously I made a mistake while mounting the clamps..

Nonetheless interesting to see that there is actually much pressure at work ..

I will have more respect now for the PSI figures!

Yeal lol thats happened to me heaps of times so loud you instantly think shit what have i done then the csr idles like a rotary.

pretty common occurrence

you can unplug the afm if that happens, it will limit revs to about 2500 but it drives a bit better than with it plugged in (reverts to a default map)

one time my r32 spat the whole lower half of the hot-side pipe (from under the airbox to the fmic) into the bushes

i couldn't find it so i had to limp it home :(

wait till you get one come half off, it runs like shit on boost but idles fine and drive fine off boost and cause it only came half off you can't see it easy and have to pull half the friggin car apart to find it was the one that joins the back turbo to the front one :rant:

I blew my cooler hose going through the NATO park near stanwell tops, I also herd the bang and black smoke, All my intercooler pipes seemed fine and I started to worry that it was something else, I decided to remove my front bar on the side of the road (had to wait for dad to bring tools which took him 2hours to get to me) and the pipe going into the passenger gaurs was off.

Massive pain in the ass especially if it's hard to get too !

How good is it though when you find it - that sense of relief that it was nothing serious :) Although the bogans in falcons/commodores flying past while your bonnets open and they scream out piece of shit skyline is annoying

time to invest:

i've never once had a cooler pipe blow off in 4 years, last 2 years at 20+psi. best clamps ever, apart from those fancy wiggins ones....

Use these, everything else sucks.

Agree that blowing a cooler pipe off scares the shit out of you, sounds like you put a piston through the block and then it won't idle, worst feeling ever.

Hi,

Yes, now that I know it is common it is -> LOL, but yesterday it was -> OMG!

I have a Nistune ECU and I was trying a new map ..

LOL good read, very common.

Get that car tuned properly with the new turbo as the stock ecu may just blow your motor.

That's good information, had I know I would have had less stress ..

It was difficult keeping the engine alive and it would not take any load at all.

pretty common occurrence

    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go. 
    • More so GReddy oil relocation kits, sandwich plates, etc. all use 10AN fittings. And same, I've only used 10AN and my car sees track work (circuit, doing laps, not 10 sec squirt business).
