GTR Dyno Results

[meshmesh]

Maybe we can make this Sticky?? Have a comparison against other GTR's with mods or in stock form.

Got my car dyno'd today, after fitting the PFC & Cam Gears, here's the result & my list of mods.

MODS: GTR Series 3 98model

Power FC & Hand Controller

Cam Gears (Settings +4 & -6)

Stock Turbos (14psi ~<1bar)

Turbosmart bleed valve

Exhaust - stock dumps, 2.5 front pipe into 3inch, stock Cat, 3" from cat back

HKS Pods (No CAI)

Total 249.1kw @ ALL FOUR WHEELS

Thanks to:

1. boys at ICE for help & advice

2. Merli from SAU for letting me know it's kw@all four wheels, & not rwkw.

Nice,

Get a 3'' dumpies and hi flow cat... You should get a bit more from that

[DJ984]

is that 14psi per turbo or 14psi all up??? I never quite understand... I know i run 10PSI but i only have one turbo ().. so that makes it easy to understand.... or is the pressure measured between the turbo(s) and the intake?....i'm confused :S

[Guest INASNT]

that seems a bit high for stock turbos!

u should have used ben at race paces dyno it gives much more realistic dyno readings

[Jamezilla]

Much higher than mine (on BMT dyno)

Very similar mods. I think I need a tune...

[Warpspeed]

Oh that is a nice flat torque curve, you obviously have the tuning spot on. Well done...........

'95 Series 1 GTR

• Apexi Front pipe, 3" Cat, 3.5" Catback
  
• Standard turbos and 'cooler
  
• Boost @ 1.0 bar (Blitz Dual SBC)
  
• Power FC
  
• HKS pods
  

234.8kw at the rears

So, theoretically, with cam gears i should get a 15kw increase.. that sounds about right.

what did u get james?

[knore]

Ahhh the amazing gtr

add pod filter = 20kw gain :headspin: :headspin:

love it

:aroused: :aroused:

will be joining the 'elite' sometime in the next year

the anticipation is killing me

Oh dear... this thread is a terrible idea.

My dyno reads lower than your dyno

[Merli]

If you think these figures are overinflated, that's because they were done in RWD...

If the driveshafts were left in and the cars dyno'ed on a 4WD dyno, they would read about 20kw lower.

Nice work guys, this info will be handy for when mine turns up at the end of January.

mine made 210kw at all 4 with same mods.

Yup...

Hang on... Isn't that what I said?

But a GTR is in rwd mod until traction is loss so in the real world that figure is probably correct, unless of course your doing 8K luanches

Hi INASNT,

They're stock as they come.. The car will be at ICE later this week or next. I'm getting the HKS EVC IV fitted, & need new spark plugs.

Hi Merli,

The dyno was done in 4WD!! "shootout mode, I think??".. not 2WD. It was done at Subaru Docklands, in Victoria. In fact it hit around 265rwkw, but that's when we dropped the boost back.

Intersting my PFC Hand Controller, shows my knock levels to average around the 13mark, max I hit was 21... is this OK?

Thanks

[sewid]

Woah. Those knock levels are very good.

[Merli]

Yup... absolutely true...

That's why a GTR that spins up 250kw @ wheels will be faster than another RWD car that spins up 250kw @ wheels...

Because when you actually take them to the road, the GTR is making more than 250kw @ wheels :) :D

Sorry mate, you said in your first post (and this one): 249rwkw, which means "249 rear wheel kilowatts"... Got GTRs dyno'ed on an 4WD dyno, we usually say "249 kw @ all four" so we can differentiate Hope that helps!

Excellent power figures for those mods! I think we all need to get some cam gears for our GTRs soon too! Did they make a big difference in spool up time as well as a good power increase?

Oh, and great choice on boost controller! Let us know how it goes and how it compares to the bleed valve!
