Piglet's Rebuild Of His Busted Tomei 2.8

This all started cause a gearbox broke,

I think it was actually 4 but that's in the past and right now if I want to drive mine I go to the garage and turn the key :)

And when yours wasn't running, I could have wandered out the back, pushed the boat out and rip skidz too. Your car was off the road for a similar time wasn't it? ?

The car was pulled off the road running. I could have whacked a stock box in it, replace the turbo and it would have running within a couple weeks.

Can't remember it was a few years though  was about the same time you broke your engine I think

Ok ladies simmer down.

Time to start taking bets on the power figure.

Apparently 480 AWKW was the most power out of a 8374 awkw (out of an Evo) Scott has seen on his dyno.

Nick (3.0/8374) went 461, 24 psi

Pete (3.2/vcam/8374) went 457awkw, 25 psi tapering back to 21 psi (120,000 turbine speed).

I don't know. It's all dictated by that magic 127,000 RPM turbine speed. What will be more interesting will be the boost level that it'll need to get there. Going off the -5 setup, it went 441 at 19 psi. Realistically, I should have just left it there.  Boost level I'm gonna peg at no more then 25 psi, tapering back down.

i know another evo making 450kw 8374 .92 internal gate at 36 psi

why stop at 25 psi

Because of turbine speed.

127k max. If it reaches that, the turbo is done, irrespective of pressure. 

Its no secret that these things have certain parameters to keep within, just like any mechanical part.

What speed are you at with your 30 or 32 psi?

and you know 25 = 127k?

is it to keep them alive or are you saying it wont anymore power beyond 127k

i was about to turn mine up to 34psi haha

No I don't know 25 psi will equal 127K. It was an educated guess... I could be well off. We will know because the speed sensor will be going back to the ecu.

Hopefully the wheel doesn't end up out the back of the exhaust. You're bloody crazy to turn it up that much without knowing what it's spinning at. Not the turbo's fault it if fails.

    • There is a LOT of stuff that can be done, it all depends on how much time and money you want to spend on doing in.  Not all ECUs will be able to do it, and the more control you need the more time and knowledge needs to be put into making it work.  If you're willing to spend the time and money and have the right hardware and skills involved there's a lot that can be done. 
    • I am impressed with all this level of adjustment. I didn't expect all this possibility
    • Correct.  In the case of the 500kw dyno plot I showed you the car actually runs two boost control solenoids for boost control and a 5psi wastegate spring.  It allows me to control how much boost pressure is applied to both sides of the wastegate valve at any point and fairly accurately control boost target as a result. I've tuned it so that it's able to target anywhere from 5psi to 25psi depending on what's needed.  The target tables I've set up in that car are Gear vs RPM, so every gear has potential for a different boost (and torque) curve.   First and second gear have quite low boost targets, third gear actually has different target boost all the way through the rpm range as it's a stock RB25 gearbox - the boost targets have been chosen to maintain a peak of 600nm (what the owner has set as the maximum torque he's happy with putting through the stock 3rd gear) but it carries that to the rev limiter.   The boost curve to achieve that is something of a ramp up, then hold, then ramp up again and the power curve looks more like a flat line haha.  
    • so you can decrease or increase the boost depending on the diet as you wish?     by acting on the wastegate?
    • That's torque and power, it's all from a single run.  The boost curve is "held back" from it's peak target in the 3500rpm to 5000rpm range from memory, so it ramps hard to something like 18psi then climbs more progressively to 23psi nearer 5000rpm.   It makes the torque (and power) ramp more "natural" and less hard on parts and traction, it doesn't feel artificially held back.
