Got Over 400kw Atw?

[Marko R1]

Not 500kw... but....

GTX35R

Caltex e Flex fuel

2000cc injectors

28-26psi

its enough for a street car

nice result & awesome artwork on the engine covers

[NXTIME]

Dan, if you can get the boost to not taper off down to 26psi and hold 28 throughout, it will hit 500rwkw

And yes, definitely plenty for a street car

[hypergear]

I should have been here 2 weeks ago missing by 0.89kws. lol

Here it is, with blessing of Queen Elizabeth plus emu and kangaroo screaming (jks, had 50c Coin welded to my wastegate port).

My car stopped making power at 431rwkws. Using Hypergear ATR43 G4 roller bearing turbocharger.

The red line was from the latest roller bearing ATR43G3 that was used for dyno scaling. please ignore it.

Factory engine with forged pistons (9:1), stronger valve springs. Stock cams, factory inlet manifold.

Run was based on E85 fuel, high mount manifold, 50mm gate. (No need for big cams to crack 400rwkws, just need a huge turbo).

Destroying that coin can put you in prison Stao.

Great result, I should have dropped down instead of trying to talk on the phone. lol.

Stands for Australian made

[Nee-san]

Should've just used a Hiclone.

[SiR_RB]

haven't had a chance to read through all these pages, but would standard rb26 camshafts with adjustable cam gears, be ok for 400-420kw ? or would they be choking power at that stage?

[Deano 1]

Jez made 419 with factory cams

[SiR_RB]

Sweet

Tune is on Friday so we'l see how it goes

[Deano 1]

Awesome man. Wish I was home : (

Can finally post in here:

Forged rb26 bottom end

Stock cams/springs/head

Precision 6266 .84 T4 divided

50mm GFB external gate

3.5" dump/cat/cat back

1200cc injectors with walbro e85 pump

409kw @ 26psi on e85

Stock cams have nothing else to give and fuel system maxed too

[gtr jet]

Have you got a copy of the dyno sheet?^

[portaz]

Wish I saw that run, so close but so little time , time for 2200 injectors and poncams

[SiR_RB]

Will upload dyno sheet when I get home tomoz night

[Piggaz]

Forgot about this thread. Time for a little update;

New setup;

GT Block
Tomei 2.8 (87 mm pistons with Titanium top ring)

9.0:1 compression ratio
260 at 10.85 mm cams. (custom grind with a much more aggressive ramp rate than a typical "Jap" cam.)

Full effort HKS/NAPREC head. (1.5mm OS valves, NAPREC CNC machining, intake squish pad removed, decked 1 mm)

Ported manifolds (to head and turbine housing)

ID 2000 cc injectors

Twin 044 feed pumps and single 044 lift pump

Nismo 0.9 mm head gasket
Nismo Plenum
Nismo intercooler
Tomei series 1 dumps (72 mm internal diameter)
Garrett -5's with ported turbine housings
Racepace motorsport twin 3 inch exhaust
Blackbox ECU (Built in conjunction with Unigroup Engineering. This ECU is yet to be released for GTR's)
Ethanol flex fuel setup
Ross Tuffbond crank trigger. (Timing is no longer taken from the CAS)
Stock airbox with a $10 paper filter in it.
United E85

Modified turbo intake pipes

Made 472 RWKW with the EBC on (highest was 474). Peaks at about 28 or so then trails back to 25.5 ish top end. With the EBC off (20- 21 PSI) it made 441 RWKW. Tuning for very strong midrange midrange more than anything. On PULP it made a an easy 425 rwkw at 22 PSI IIRC

Fuel system shouldn't be maxxed at that power? Pump getting full voltage?

[Piggaz]

We must tune them richer over here

[SiR_RB]

Injectors were running out sooner so we had to bump up the base fuel pressure to 55psi.....

Needs 2000cc injectors and another intank pump at a minimum..... Plus cams

What cams would be recommended for my setup??

[Piggaz]

^^^ is your head relieved for big lift cams?
