I drive a R34 GT-T and have done abit of modification. Upraged fuel pump, bosch 1000cc injectors, link G4 plug and play ecu, greddy intercooler, kiwagana 76mm turbo, spitfire coils and a GFB boost controller, it was tuned at 18psi or so giving it 266rwkw. Tonight i was giving it a few test runs and there was a loud bang and then the boost has gone right back to about 7-8psi. I looked under the hood and noticed a small tubes clamp has blown off and the tube had came off aswell. i have circled where the tube was in the photo below (it was lowest tube on the top section) and air appears to be pissing out from where the tube was attatched. with it being dark i havent been able to look fully into it all. the car still runs and the only problem (so far) is the boost problem. Any ideas on what blew off the car and any ideas on how to fix my problem?

I don't think that small vacuum hose is going to account for a loud bang.

The hose (we are guessing) you circled obviously needs to be reconnected but I suspect if you have a good look around you will find an intercooler hose has come off.

Its a bit inconsistant given you heard a loud bang and as said above, you would normally expect a loud bang to be much more than simply a vacuum hose. Unless its the fuel reg hose and it caused the tune to go haywire and it was in a backfire out the exhaust

Obviously reconnect that hose, but i would agree you have probably also popped an intercooler hose. Get underneath and give them a real good look over as they can often look like they are still connected properly after they have popped off.

Thanks for all your suggestions guys. After getting up this morning I have gone back under the hood and haven't seen anything unusual. Checked connections seeing if anything is loose or leaking but to no avail as of yet. If I can fix this problem is it going to need a retune after the severe boost drop?

As normal the masses are right and the main problem was the first pipe from the turbo out to the intercooler had let go. Cheers for all of the input guys, it was very much appreciated! :-)

My vote is this, fuel reg blown off would make it do something funny, probably also the clamp smashing into the bonnet along with it, might even be an intercooler hose missing.

I've blown my intercooler piping off a few times with the old clamps I had, made a huge bang as the pipe would smack the bonnet and then I'd get a huge cloud of black smoke/backfires, sounded pretty bad when it happened, thought I had put a rod through the block the first time.

try using T bolt clamps instead of worm drive ones.. those babies will make sure nothing comes loose...

as soon as I replaced mine with these I never had a problem again running at 18psi

I have had a problem using them with a dodgy bit of pipework. I was in a rush and didnt weld a lip onto a piece of pipe and it blew off at 20psi . Those clamps are heaps better, but not going to fix other issues.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
