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.

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

      Comfortable replacement seats for R32 GTR

      By GTR_JOEY · Posted

      6 foot 91kg.   Thanks Brett, ill have a look into them!   Whoa 197 haha, I'm about 182 but not that far behind you in weight. My back is probably a little wider than most people my size and weight so I would most certainly need the XL seat by the sounds of it.  The car is insured to drive 1000km a year (might up that at some stage) but it would likely take me at least 5 years before I would ever get close to 15,000km. If I don't buy the real ones I kind of feel like I'm cheaping out though lol Spent all this money on good quality parts every where else just to cheap out on the seats? probably my OCD.  I did find these guys who are more local to me and have copy seats in stock.  https://vosta.com.au/collections/reclining-bucket-seats/products/japan-stadia-ii-gradation Or if I want to go genuine   https://www.carmodsaustralia.com.au/brand/bride-racing/?srsltid=AfmBOooYKfh5btzB8-ezRTTokM0AqQ3GyWKcfutaMRWBzosRLNSFQhLt

      Good. I was worried we were still talking about the block. Yes, larger baffled sump is a good idea. Do not touch the pump unless you're going on a whole build saga. Read the oil control thread on here - at least the last 100 pages or so. We drew some reasonable things together in there. The short version is that venting the sump is more important than almost anything else you do.

      Perhaps just get a proper mechanic who is good with Nissan autos (they were more or less the same across all the RWD, FWD, 4WD cars at that time, even if they were actually different boxes) to give it a good going over. He might be able to plug in a Consult or other scan tool and find out if it's got some fault codes. Otherwise, my approach to the problem if not liking the way the auto was workign behind my RB20 turbo, was to drop it on the workshop floor and put in the manual box that it really needed. That solved all the auto problems.

      Gotcha, I mean that is at least good to hear. Are there signs, or troubleshooting tips to make sure the transmission is operating properly?
