I'm not being a dickhead, merely trying to understand.

I don't want to sidetrack this thread any more. I am merely repeating what I have been told. It might be absolute cr#p, but I respect the people who told me. I think the thread you chose shows the range in quality of information on much of this forum. Some people know their stuff. Others don't. I cannot give a sound reference for my comment, so those reading should not put much store by it.

Cheers.

Syfon: Rohans GTR has catback only, pods pfc and running 14psi (1bar) - made 240awhp on that 40deg day at autoworx a while back where everyone elses' numbers were hammered.

Even my Stag pulled 222awhp on that day only running 12psi.. what's your point?

His point would be that the heat made him lose power, meaning his car would have more than the power figure it pulled on the dyno

No, I don't think so. He said Rohans' GTR made 240awhp while everyone elses numbers were hammered.. implying that Rohans' figure wasn't low while everyone elses was.

Yes it was hot, and yes certain ECU's were pulling a lot of timing (my Haltech for example, I was down nearly 100hp), but I really fail to see what that comment had to do with anything.

Top Racing's dyno is the highest reading dyno I've had my car on in Perth. Might be why Canute's power figure seems high.

If you guys want to compare power properly, use the same dyno on the same day or go get some quarter mile time slips.

280kw = 375whp. Thats more than mine makes with all my list of mods at 1.3bar. You ran 1.2bar/17-18psi on stock turbos? Where did you get yours dyno'd?

Say if you do a turbo-back exhaust (de-cat), pod filters, boost the turbo's a few pounds higher than factory and install a power-fc, how much awhp should if expect within reason on a safe tune?

Syfon: Rohans GTR has catback only, pods pfc and running 14psi (1bar) - made 240awhp on that 40deg day at autoworx a while back where everyone elses' numbers were hammered.

Thats very low... even though temperature is high.

Correction - it was 1.3 bar. My apologies. It was tuned by Steve Thomas using the dyno at Top Racing (in Shootout mode, see attached). This was a good example of what you can get out of a GTR with only a few mods.

Cheers. :/

That make a lot more sense now. :/

I dont really think these kinda information consider derailing? Merely providing the future owner of a 33/34 gtr owner whats sort of figures he can expect with the type of mods he's putting on.

Anyway regardless of which gtr you end up getting, tune it to 0.9 would be safe and good enough for daily driving. That extra power is f**k all when you've got a really good tune imo.

As Canute said, let's not sidetrack this thread any more. I will be viewing a few more R33 GTR's on the weekend and will post updates as to the conidition etc.

Cheers

Char - yeh the link is dead because the R34 GTR did sell to the guy who flew over from Adelaide.

Are you sure it sold to Mr. Adelaide? Cos I'm pretty sure I saw that white 34 GTR at Curtin yesterday afternoon :huh:

I specifically remmeber the black mark, about 15cm long below the driver side headlight...

Or maybe he bought it and is waiting to ship it over lol. Dunno.. if it was me, after I'd paid 40k for a sports car, I'd want the keys and definately wouldn't let the old owner still drive it around to uni :(

I think he was implying that everyone elses numbers were hammered so Rohan's probably was too. Because Rohan had never had that car dynoed before, so he had no figure to compare it too. But everyone else was losing lots of numbers, so he was implying that Rohan probably lost a bit as well.

I think anyway lol, that's how i read it.

all dyno have Correction factors. Therefore they adjust the power depending on the intake temp. so on a hot day the dyno will increase your power.

That is why it is common to see dyno read outs with high intake temps (overly high) as it will increase your power output

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
