Yeah you can't see what the back pressure is doing by looking at a dyno plot - sometimes it can show up as the power falling over prematurely due to the tuner having to pull timing to avoid detonation before MBT. Funnily enough this dyno plot looks like what you could expect to see in that case, if it weren't for the claim that the early drop off is due to wheelspin. Silly rolling road dynos...

Will be interesting to see how it goes on a hub dyno, and how the engine/turbo lasts at that power level if its going to be used on the track at the power level at all?

At face value, very nice power level and spool for a convenient and affordable package :blush:

Didn't Mafia make over 300wkw with a .63a/r GT3076R?

I think it was Geoff Raicer (of Full-Race fame) who once commented on a forum that torque starts declining when ex manifold pressure exceeds intake manifold pressure in a turbo setup. I guess this makes sense as it is at this point the VE would start declining resulting a drop off in torque and therefore hp. Hopefully the decline doesn't happen too rapidly resulting in a short torque/powerband.

The aim of the game is to get torque to build as early as possible and hold it flat to the redline - easier said than done with smaller responsive turbo's.

That was all the way to rev limiter. Drop off was mainly from lose of traction. Sam did not back off early. You can double check with Sam if you want.

The Main point is that we've managed to controll and hold boost all the way to 18psi using an internal gate setup on a .63 turbine housing.

and

This turbo has made the most power out of all the R33/34 high flows there are with 98 RON Fuel.

This is a very BIG claim that is untrue.

My car as a hiflow turbo form Adelaide Turbo Services and GCG and has made 298.2RWKW and couple of years ago and will be going back for a retune in a few weeks.

except your are runnning RB27 stroker and this is a RB25 stock. Also not been straped down.

strap down or hub result is going to be soo interesting to see. can't wait. :devil:

+1 :D Cant wait to see more results!

I will be getting a high-flow done with tao so always good to see recent R&D

Has this been run on other dynos? or was it a one off?

I would also expect a bit more than 116mph from that power figure, been that Ive run and many others have too, 105mph with 180rwkws

Just the same way 2 turbos can make the same peak output and completely different delivery, 2 tunes can do the same.

He might have the numbers, but might not have the torque to get the MPH down. The ET sounds about right for the car and MPH.

Torque wins races, pulling timing and fuel doesnt.

"This turbo has made the most power out of all the R33/34 high flows there are with 98 RON Fuel"

Sorry but i didnt see anywhere in his claims that it was the highest power figure on an RB25 or any other motor or level of mods.

    • I like it when the counter chick leads you out the back into the racks and says "have a grub around in here and see if you can find what you need. I'll be back in a few minutes. Just left me in front of a massive motorised shelving system and 2-3 million fasteners, so I could find a peculiar SS shoulder bolt with cap head. Gotta love country towns.
    • I used this https://osgiken.com.au/product/os-giken-os-250r-lsd-gear-oil-80w250-1-litre/   shut my nismo 1.5 pro up by heaps…. Not silent though. Gives the car character and personality. It ain’t a carolla. If you want silent, put a quaife in it.
    • It's about the same time for me from Bunnings, or the Fasteners. My big push away from takeaway food, and gluten in general keeps me away from the Bunnings Snags too! Weather up here, I've been out for two walks today in the beautiful sunshine. Had a few little drizzles, and some wind, that honestly, a tin of beans and I could compete on how harsh she blows Thankfully, being this bit inland, we're not getting anything much really. Will probably pick up a bit more when/if Cyclone Alfie decides to come ashore. A few areas in the GC though, and south into NSW are really getting smashed though! Right now, I'm just annoyed Alfie hasn't hit, as I'm not allowed to crack into the BBQ foods like the bacon and eggs until the Cyclone hits "In case we lose power"...
    • I love fastener joints, the price difference between them and joints like Bunnings or Super Cheap is amazing, and they either have exactly what you want, or they can get it to quick They have even given me some for free when I only needed a couple of specific size In saying this, I have paid premium for fasteners from Bunnings if they have the sizes I need, but only for convenience really, as my local is only 10 minutes away, the Sushi joint near them is also a consideration  How's the weather Matt? Stay safe mate
    • Wideband is worth setting up if only for tuning purposes. I would not mess with the ignition system unless there's a misfire. HKS crank trigger is popular out here for the relatively easily sourced Denso crank sensor, not a bad idea to install as well regardless of power level on a standalone. Boost leak test is worth thinking about. Oil pressure sensor tied to a fuel cut isn't a bad idea either. Getting the tune figured out is a good idea. Without putting eyes on it and getting under it there's no way for us to tell you exactly what it needs but most likely you're down to the last 10% that will make a big, big difference in how happy you are with the car.
