Lets try this again

R34 GTR

593awhp/436awkw @ 24-25psi

RB26/30DETT

HKS GT-RSs, yes fancy -10s

250 x 9.15 poncams

ARC cooler

ID1300s

custom twin 3" into single 4" exhaust

Syvecs S8 ecu

has done 623awhp/458awkw @ 28psi

Rebuilt with 0.5mm bigger Wiseco pistons

New UE 260 x 10.8mm cams

OS88 with alloy shaft

Sold dyno wheels so was dynoed on 275-35-19s instead of 255-40-18s so revs are lower then indicated

Also Scott changed from Dyno Dynamics to Mainline which apparently reads lower

[gmchaser]

I would love to see the above with a -5s comparison and the same boost. Would be good if it still makes peak power at 7000rpm but push the peak torque down 500 to 4000rpm.

[XKLABA]

-5s are to small for a 3.0, would taper for heaps topend, would love to see it against the set of Hypergear cored -5s I ordered and Auspost "lost"

[whatsisname]

Had the car back on the dyno today.

R33 GTS25t

RB25/30DET

FP HTA GT3586R .85

256/264 x 8.8 / 9 HKS cams

Link G4+

3" exhaust

Twin Walbro 460lph E85 pumps, twin feed lines, twin entry rail, ID1000, 53psi base pressure

462.1kW at 25psi (see video)

780ish Nm

Dyno doesn't have rpm input (normally set to road speed) so scaled rpm as best as possible but think it's out by a couple-few hundred rpm making it look laggier than it is.

[acsplit]

How much boost?

Very similar build spec and result to acsplit above.

My goals are for a responsive track car I can daily on 98 - drive and fill up anywhere.

RB30 Bottom end w/ Ross Racing Pistons & Spool forged rods

Garrett 2860 -5 Twin Turbos

Tomei Expreme Dumps

Low comp 7.85:1 (to keep things safe on 98, YES I'm staying 98 for a while)

ARP M11 Head Studs

Nismo 0.9mm Metal Head Gasket

+1mm Supertech valves with Supertech springs & retainers

Tomei Pro Cams 260 10.25mm lift

ID 1000 injectors

Autronic SMC / 500R CDI (Super Old School!) firing through Splitfire coils

Adj cam gears

Nitto Oil Pump

Single 044 pump & 2L surge tank

[Pezhead]

19.5psi, so still a bit left in it

[acsplit]

Nice!

Same with mine, pity traction won't exist.

We have it ramping up about as flat as possible

Update:

After spinning bearings at my first track day, I required another rebuild.

I decided to go from a single, back to a more factory looking setup.

So, same setup, with trust 618zs turbos.

10cm housings.

Hpi dumps.

Twin 3" to 4" exhaust

Came to 380rwkw.(or awkw, not sure which).

Looks like fun, even after the 3rd time reading it, lol

[whatsisname]

Finally fitted the new 3.5" dump and front pipe combo' after getting it back from ceramic coating.

Almost no change in top end and peak power (462 vs. 463.7kW @ 25psi on E85) but solid gains in both response and peak torque.

Apologies for the out of focus and cropped dyno sheet image - will upload a proper one after I pick it up tomorrow. The improvement in area under the curve is pretty obvious.

[whatsisname]

Roughly 325Nm @ 2800RPM

Close to 600Nm @ 3500

850ish @ 4200

[whatsisname]

And for a very rough comparison, here's the dyno run (on the same dyno) from a supercharged VE Maloo with a cam/heads package running 13psi boost.
