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.

'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.

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.

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 :D

that seems a bit high for stock turbos!

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

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

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 :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!

      Curious if you've discussed this with them, maybe they can remove it for you since you requested it not to be coated.

      Grind them off, drill them out. Repair any rust on the other side. Start again from scratch.
