Kw Bingo - Guess The Power Output

[Tangles]

Wow. That's not much power!? Must be a very conservative tune..

No.

From experience (ie been there done that) thats about right

could of leaned on it a little and seen 160rwkw's ish

BOS 3" split dump pipe 12rwkw

Catco Metal Cat 3rwkw

Trust Power Extreme 2 cat back zorst 10rwkw

K&N Panel filter 2rwkw

R34 Intercooler 0

GTR Fuel Pump 0

AFC Neo computer 15rwkw

SITC computer 8rwkw

say thats around 50rwkw in extra zoomph as a guestimate, add in the 110rwkw standard, at 10psi.............

nice safe tune and a conservative power reading is better then 15kw higher and leaning on the engine.

my 2c

bet it feels nice to drive hey !!

nice work, enjoy it

Tune is as I expected too, minus the SITC so could get up to around 160 if pushed it. I will get a FMIC eventually no doubt anyway.

It is very nice, I even had to 'rush' to work as the exhaust install took longer than expected. A nice excuse to open it up a bit

There are so many speed cameras on Sydney roads though .. hope I didn't make a donation, spent enough today already !

[wolverine]

no FMIC or SITC and 10psi so all round a good result. congrats.

[GoldZilla]

OK, the results are in and the winner is .....

Tangles

Max power 152.9Kw at the rears running just under 10psi. This is a Series 1, not neo motor by the way. And an auto

Goldzilla ... sorry I missed your post as my PC at home is dead and I went down there first thing this morning. Is yours the green one coming in for a 'trial fitting' next week ??

Speaking of fitting, the Power Extreme cat back zorst needed a fair bit of manipulation to line up unfortunately. I guess that is the price of mixing and matching local dump pipe and cat with jap exhaust. A word or warning for others I guess, the BOS dump and Catco cat may not line up exactly like factory

Hey Stu, nice result. No worries about meeting up this morning, it's all good.

Yeah, that's me getting the trial fitting done on my car - I've got the JustJap combined split dump/front pipe going on mine, and seeing as a few people have had some issues getting theirs on their cars, I figured I'd best get them to do a test-fit first so I can either get a refund or sell it if indeed it doesn't go on.

I'll be getting a baseline dyno run done first, then if all goes well, the new dump pipe will be getting drilled for an exhaust temperature probe to be fitted, then the install, then a quick run on the dyno again to see if any gains have been made.

I'm not really expecting much of a power gain, as I haven't yet got any way of tweaking ignition, fuel or anything else. All my car has is a 3" cat-back exhaust and a manual box (which should provide a minor gain in itself due to slightly less slippage). If I get improved response, then I'm quite happy for now. Suspension tweaks are next, then the hunt for an FMIC and computer.

The boys there are very helpful and professional, so they won't BS you if it doesn't look like it will fit.

The muffler shop had to heat and bend the BOS dump a little to get it to fit also, plus the flanges on the catco cat are a little off and it has a small leak. Shows that nothing is perfect out there unfortunately, especially for stageas

[Tangles]

Man, I can taste these forthcoming Jellybeans already

[wolverine]

tangles,

allowing 60kw for drivetrain loss on a manual, does the slushbox suck about 10-15kw extra.

[Tangles]

well thats definately one thing Im not entirely sure of (never driven a manual rb25det)

but its a theory I work towards.

ie my Stagea at the moment has say 195rwkw (was 190 @ 14psi with restictive muffler at last tune), if it was manual I have no doubt you could add 10rwkw to that and boast it had over 200 at the rears.

my next tune in 2.5 weeks time @ 16psi should net around say 210rwkw, surely thatd be more towards 225-230rwkw with a manual ? dunno, but thats what my readings on this site suggest.

* munches on jellybeans

* farts, oops sorry did I type that

For those interested, the difference between awkw and rwkw (with the front shaft removed) is ~20kw.

This was on 2 different dynos so give or take 5kw or something...

It helps to know when comparing power/weight ratios with other rwd cars. Also in the stagea's favour is the excellent 1st gear ratio (even in the auto) and 4.3 diff ratio, = great acceleration off the line, at the cost of fuel economy. Of course you cant compare cars perfectly this way but it is a (very) rough estimation...

And for what its worth, its also been proven that the Stagea will be quicker in AWD mode than in RWD with the front shaft removed, despite the higher kw reading for RWD.

So I'm guessing a RWD-mode stagea (assuming same weight, which RWD-only stageas aren't...) with 200rwkw would be a close match for an AWD stagea with 175-180awkw. Not taking the driver into account - this is just purely about comparing power outputs of similar cars.

None of the above can be used as a strict conversion, but it is a fairly close estimate IMO.

it's exactly as the thread title states: Bingo. It's useful purely as a guage of %power increase provided you stick to the same dyno. It gives you an idea, but no dyno reading is definitive.

[GoldZilla]

Alright, I had mine in on the dyno at Unique today, and confirmed that the JustJap combined split dump pipe and front pipe does NOT fit, which was rather annoying...

Who wants to guess how much my output was? It was leaning out up high when the high boost kicks in around 5,000rpm or whatever...

[Tangles]

mod list plz?

118rwkw?

[GoldZilla]

mod list plz?

118rwkw?

Hmm, Major Tangles, there's not much to say here.

• Manual conversion
  
• 3" cat-back exhaust
  
• R33 series 1 (steel compressor wheel) turbo, which was a drop-in replacement for when I blew my turbo back in November '05
  

...and as far as I know, that about covers the mods. I haven't actually made any performance mods to it since I bought it back in October 2005.

Any other guesses?

I'm guessing none of the boys told you anything, Andrew? I was gonna exclude you from guessing, because I thought you might have seen/been told of the results.

Nice result for yours though!

[wolverine]

sooooo what did u get nick?

[GoldZilla]

Hmm, I was expecting 125-130rwkW,

It was...

It had me stunned too! Lean-out power FTW! But risk of melted pistons (or worse) FTL!!!

New fuel pump coming up in a few weeks, and until then it's cruise, no major loads, and no big revs...

[jasevr4]

That's why I was suprised with the power figures above!

Top stuff Nick.
