hey guys 5 weeks ago i got my r33gtst tuned at creatd on 13psi

r33 gtst with supporting mods and a standard hiflow r33 turbo on 13 psi made 220.6rwk (creatd)

today i got my new clutch installed at EAS and id thought id give it a power run too see what i get on theirs.

196.9 rwk

surely it cannot be right. i mean it is a hiflow turbo...car also has a pfc, full exhaust, z32afm, injectors, fuel pump, blitz fmic.

car is in immaculate condition mechanically.

very confused... i have heard of variances before but thats a big gap

Been convered many times before. Every dyno reads differently. From being different type ie hub, roller whatever or from not being calibrated before a run. Alot of variables can affect the power outcome. 196rkw is low for your mods, i'd say the 220 run would be about right. Just stick to one dyno so you can have some form of comparison.

yeah as above been covered a heap of times now.

I take it the ambient temp and humidity etc was all roughly the same? fuel, oil plugs etc?

to get any real worth while numbers i'd say stick to the same dyno and also i'd say same operator..

and same I agree with MR 33, i'd be taking notice of 220, with hi flow and pfc etc 196kw's seem way too low

i think there must be a problem as i had a couple of runs on my mates driveway on the farm. only 2nd and 3rd gear and abit in 4th i was only a car or so infront of him by the end of it. he has a r33 gtst only on 10 psi (stock turbo) and cat back exhaust.

i dont know what could be wrong :D

take it back to the first place, if it makes the same power your car is fine. Then if its struggling to hold a stocker I imagine that reading is out 220rwkw is a shitload more than 140 or 150rwkw they make stock, then maybe the first reading is more accuarate

it actually goes crap phil. very dissapointed.

Well if its going like crap - there is a problem dude :)

Time to workout whats wrong, something like a fuel reg could have failed, injector leaky maybe?

Many options and fiddly ones too

we found the problem. eas took off the actuator today because he was going to tune it but couldnt due to not having his software.

we monitered the boost tonight and was tapering off to 11 psi instead of 13 where it was set at from creatd originally.

very dissapointed with that

"dont hold back

is there anybody out there?

feeling something

engage me, let me breathe the courage of your actions

dont hold back make it before the good

the truth is, i am not your cure but i can help you

find a way to reconcile the dark"

BOOOsT! As long as it is a highflow... lol. Cause I was told mine was, 16psi later. BANNG. I never even found my exhaust turbine OR the shaft haha. Guess thats what you get for running no cat and a straight through exhaust hahaha.... The intercooler and throttle body did a pretty good job of collecting the compressor wheel. :domokun:

On the plus side, I ended up with a sick as $20k portable smoke machine with music. lolz

      Question about BoV on RB25DET NEO

      By Murray_Calavera · Posted

      You've just discovered a really good reason to tell yourself, yes, I do need to buy an aftermarket ECU. Put the MAF in the bin. Slap in the new ECU and have a think about what turbo sounds you prefer.  Do you want a 90's style BOV wooosh? Do you want a hektik tsututututu?  Mate, can't go wrong. Just gotta get that ECU and the world is your oyster.

      Question about BoV on RB25DET NEO

      By Kapr · Posted

      Hi. Iam just curisou about this topic. I saw this video. It is about Greddy Type FV2. I know that BoVs are about that sound but how and when to use it? I read some topic here and from what i have understand on stock RB with MAF there will be some "problems" if you use this BoV? It vents the air in to the atmosphere and the MAF on stock car needs this air back in to the intake and not out? Or is it wrong? If so...i saw you can put some adaptor to circule air back...but does that not "loose" that sound? I saw another BoV from Turbosmart and it has two "exhaust" like ports? One is for the stock tubing for letting air back and one is for "sound" and let the air in the atmosphere? Can someone please explain? This is the Greddy one:  And this is the Turbosmart.     THANK YOU!! EDIT: So i read about this topic some more and i if i understand that correctly: That Greddy can function either like BoV or 100% Bypass valve? And that Turbosmart is what they called hybrid so you can adjust what and how many air can be vented out or back in? Is this right? THX!

      That dirty voltage drop is the culprit I suspect

      The Ls1 R33 Of Fury

      It's about time I start work on my sun tan. So I knocked up a few parts that will all combine together to become my new power steering reservoir. Now just to produce an abundance of UV and IR rays while melting a heap of bits of alu to become one... Well, that's after I put one more hole in it for the return line to plumb to. It likely won't be this weekend, as Sunday I'm meant to be in doing some last minute stuff to the AMG race car, and the weekend after will be filled with non my Skyline stuff, followed by Bathurst 6 hour. So I don't expect to get to melt metal for at least 3 weeks.   I also managed to stuff up and start cutting the hole for the res to pump pipe on the wrong side of the line... It means instead of the lines being nice and tight against the inner guard, they'll be out off the guard.    The size of it means I should end up with about 1.8L of power steering fluid, and still have space for another half a litre before it reaches the overflow/breather. This is wayyyyyyy more capacity than factory, which should help keep Powersteer oil temps lower, and the design hopefully allows it to prevent any aerated oil being able to makes its way down to the bottom as it'll have a couple of baffles and some hopeful trickery to force air bubbles away from the bottom.
