Who is running the stock GTT turbo at this sort of boost?

How long have you been running it?

I got my GTT tuned recently and they tuned it with this boost. I figure I can always drop it down a bit but it might mess around with my tune?

I would probably just leave it up at what it is, if its reasonably safe.

I deliberately tried one at 12 psi, lasted 4 laps (1 warm up and 3 fast) at Oran.

Ben's lasted 5 laps at Wakefield at 12 psi.

I warned a guy running 12 psi that it would happen to him.

He reckoned it wouldn't 'cause he never drives on the circuit

His got his ceramic in the cat disease driving hard up the hill from the Mooney Mooney bridge on the F3.

Cost him a new turbo and a bottle of JD (he lost the bet :rolleyes: ).

tick....tick......tick

:P cheers :(

Uh, this might sound like a really odd question.

But if you blew your exhaust turbine wheel pretty bad, so that it wouldnt spin the compressor any more. Then effectivly, the car will always be in VAC, will the ECU still be able to run the car correctly at say 5000 when it would normally be in +ve pressure?

I can get it at 5000 in vac, just doing down a hill in second. But... i dont know if thats the same?

Essentially, if turbo breaks, can the car still run/be driven normally?

ALSO, does the cat get damaged much when blade peices go into it?

In the examples above, all 3 guys drove their car home without a problem.

:rolleyes: cheers :P

Yeah, my compressor wheel still spins with the air going through it, but it's rubbing on the housing, and it squeels like a banshee!

Still drives though. Just doesn't do it in any sort of hurry!

Is the R34 turbo weaker than the R33? I was going to get my dyno tune (on my 33) done at 12psi so atleast the tune would be good up to there..then back it off to 10psi for most use. Maybe I'll go back to 10psi then too be safe as maybe on the dyno at 12psi the turbo will blow up :rolleyes:

Thanks for all the replies guys.

The reason I ask is because a friend of mine ran a stock r33 turbo for 6 months on about 15psi with no problems at all.

And I have spoken to a few people around the place who run them on about 13-14 daily with no problems.

But you certainly cant ignore the broken turbos in this thread.

If my car is tuned for 14 will it run badly if i drop it down to 10 with my avcr? I might run it on 10 for daily and pop it back up on weekends... haha

there's another factor to consider.

14 psi on a stock computer ain't as much as a problem as 14 psi on a PFC running timing and 12.0 AFR.

Lots of timing and lean ratios, = HOT gas.

The ceramic turbine gets too hot which makes it delaminate from the shaft.

Hence, cooler exhaust gas, less chance of blowing turbo.

Not likely I wouldn't think on a single turbo.

When you blow the wheel off, the are normally at WOT and by the time the thing blows and the you realise, the thing is already embedded in your cat!!

    • 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.
