Dam straight Damo would rather do SAU them heroin gts4 are 4.1 because they share the same parts from the gtr i think r32 gtst is 4.3 because of the lack of torque from the rb20

Hey Pete its ceramic and after 5,000 rpm it sounds like a supercharger whistle so now I'm not boosting @ all and I've taken as much boost out of the manual controller as i can so its basically running factory boost to which i'm not using trying to drive on 0 or neg vacuum

Sounds like you've lost a little bit of the impellar which probably just shot out of the exhaust.

I wouldn't be doing too much driving if I were you because the blades can get fairly unbalanced and shatter now.

OK if the pieces shoot straight out your exhaust.......not OK if a piece gets caught between an exhaust valve and seat.

oh what happens then and when I'm on negative vacuum my understanding is the turbine isn't spinning?? :(

Wouldn't have thought it would stop spinning altogether but as long as your under boost I can't imagine the thing would fly apart.

You would think that the ceramic has gone but you never know, it could also be something else?!

My old 32 was doing this about a day before the rear tubine let go and lodged itself in my cat, as SLED said i really wouldn't wanna drive the car that much cause it sounds like the turbo's close to death

when mine blew i was in town and had to drive my car to woodcroft to my mates to fix it, was a f__ked drive with no boost trying to get up south road

      Yeah nice idea, you mean to suction it to the gauges? I hadn't thought of that.

      Why am I hitting a power wall with my stroked RB25?

      By Dose Pipe Sutututu · Posted

      A few suggestions: Do you have the option of retarding your exhaust cam gear to bring the power band over to the left? VCT would be turned off after you make peak torque, you see the power/torque will decay faster with it left on all the way to the limiter Once VCT is turned off, you'll find the motor will take a bit more timing being ramped in Send its mum, more boost! Of course, depends on your exhaust pressure.

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I was back on the dyno again yesterday after completely revamping my methanol injection system. I was making 440kw at 19psi. Great, this is more then I was making last summer with my old meth system at that pressure, and I figured it would be smooth sailing up to 30+psi. We continued increasing from there and by 25psi, I had only hit 455kw. Dyno sadly lost utility power at this point and I left. We seemed to be on course to hit the same power wall as last summer (477kw@27psi). This is a built RB25 S1 stroked to a 2.8. Built and ported head with Kelford 272/262 cams. Precision 6466 Turbo. Tuner last year believed the power wall is a mix of RPM limitations (Hydro lifters/Limit set at 7600RPM) and fueling. With my new meth system, we're seeing zero knock now but it still won't go up.  What else can I do at this point? Here's my train of thought.  - It's clear from the dyno graph that I would easily make power to 8500+RPM but I'm limited to 7600RPM. I could risk increasing my limiter, but hydro lifters have me worried. What are my options here besides going NEO head or solid lifter conversion? I'm rocking a 1.05AR turbine on my 6466. Would dropping down to a .84 help shift that power down in anyway? - We're only seeing roughly a 30kw difference at the top end with VCT on or off. Is this normal? I want to confirm VCT is working properly. - Should I look into other cam options?  - Should I just keep increasing boost and see if she wakes up later on? I would expect to hit 600rwkw around 35psi with my 6466.
