*points to Matts graph*

Looks like it's ramping up fast to 20 then tapering down to 17

Interesting...what turbo? Ex gate? Return cooler or straight piping?

I'm on 15-16psi

Guessing from your slightly better response my turbo is actually slightly bigger (unless you've done more than bolt ons), however my turbo gets a bit choked up top from my cooling and exhaust setup.

Almost the same setup as yours. Yours seems to hold torque for longer though, only just.

Yeah that's weird...shouldn't that produce more power at the same RPM / speed though?

Though that assumes runs done in the same gear and diffs. I don't know how dyno dynamics calculates engine torque...obviously some sort of correction for it; maybe it's open to

variability.

R34 OP6 Hypergear Highflow, Internal gate, cheap Returnflow cooler, standard cooler piping in bay, scotty's intake pipe (which doesn't quite fit and I need to ask him to modify it since it doesn't line up with the turbo and the airbox at the same time...)

Pretty sure the restriction is the rear housing not being able to flow enough

Ah yeah. Mine is an HG SS1PU, which from memory has a slightly larger rear than the OP6 highflow...but I made him match it up to a bored out standard Nissan comp housing up front for dat dere stealth (that could also be choking me out up top). Using his preferred comp cover Stao made 290+ with an SS1PU on his car...albeit Trent's dyno.

Intake and cooler piping is standard with a return flow, so they do sound very similar setup-wise. Could also be that your turbo is simply a newer / more efficient model or a difference in engine health.

Pretty damn good turbos I must say, I've had mine on for at least 50,000 now and running flawlessly.

Brought it home yesterday, pulls like a freight train... midrange definitely changes a car way more than top end power does. before it was breaking traction (265 ad08r) at the top of 2nd and chirping 3rd, now it's breaking traction for most of 2nd and if I change into 3rd hard it'll keep it going. Need to get used to that...

Had some slight coldstart issues when I started it up tonight, started and idled fine, but touching the throttle during the first 30 seconds made it choke and revs dropped down to 400 before it recovered itself... fine when it's warmed up (approx 2 minutes)

Sooooo, best of luck to my neighbours with it idling for a while at 4:40am on Saturday morning

you should be a easy 4 sec ahead of me....

Thus, why I've got work to do... Need to build confidence and learn how to turn in correctly...

ALSO, WELL DONE EVERYONE!!!!!! Page 3876 was purely about cars, not a single mention of politics, housing markets, vase selection criteria or which limited edition sneaker is just retro enough to be cool without being pretentious...

Pretty normal for E85 to be unresponsive and choke up with a cold engine. Spark plug heat range prolly a factor too.

Once started I can use the throttle immediately, but I always roll it on slow...if I stab too quickly idle drops. It also need a bit more revs when cold and letting the clutch out for take off or it will die in the ass. After a couple mins of driving or idling it runs fine and dandy with dat super response, but I've learnt how to drive it so that I can start it and start driving basically straight away.

As for actually starting, that depends how pure the E85 is in the tank. While there's still some petrol in there, starts will be easy. With pure E85 and on cold mornings mine can take 2-3 cranks to turn over. Helps to add a minuscule amount of throttle as I turn the key. Warmer weather and it's first crank good to go.

    • Ok I get you. But isn’t the butterfly intake a headache with the +T?  see this is my plan so far but please advise me into the right direction.  Nistune Ecu, 1000cc Bosch injectors, TD05 or TD06 Kinugawa turbo using stock rb25det exhuast manifold, walbro fuel pump unsure of model I think it’s 450/460, spitfire coils and sparks to suit and a R35 MAF sensor and boost sensor.    I was thinking maybe do a cheap eBay plenum $400-500 or try find a stock det neo intake. I think I’d port match it so it’s getting the full capacity but open to advice please.  Thanks 
    • The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG has not responded to my emails so far since purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.  
    • There's a good German place in Brisbane if youre up for the drive 😛
    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
