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!!

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
