Vipec Plug and Play ECU for R34

Deatsch werks 1000cc injectors, (+ complete fuel system)

Fuel BP 98

436hp @ 1.15 bar (16.6psi) (I will push harder once i have ironed out any bugs with the new setup.)

i think it works out to be 350hp/atw

Tuned my mark @ MRC

Brae High mount exhaust manifold

HPVA 50mm external gate

Xforce 3inch Cat back exhaust

100 Cell Cat

Profect B electric boost controller

ATR43SS2 .70 comp externall gated

4inch intake pipe

Adaptronic Plugin

The SS2 maxed out touch under 360rwkws (359.3rwkws) on 22psi of boost.

Boost:

its surprising of how much power and torque it picked up comparing to when its internally gated and fitted to a ported stock exhaust manifold.

Yellow / (pink due to no ink) is SS2 on high mount ext gate plumb back @ 22psi

Red is SS2 on ported stock manifold @ 22psi

Blue is SS2 on high mount ext gate plumb back @ 20psi

Also introducing Drift Havoc's R33 with unopened Rb25det engine running the same turbocharger similar setup and same fuel. Build up blog is linked below, Very good example for modifiers.

Ok finally tuned.

Big thanks to Andrew at Hyperdrive in Perth very good service.

Apexi Power FC

JECS 750cc injectors

3.5in turbo back

Decatted

Turbosmart dual stage BC,

Boost controller was causing dramas due to not being able to bleed enough air off and boost drops off slightly from 3500-4500 right in the midrange all because of a shit boost controller

Otherwise very happy with the result.

Same spec as above ^^^^^

Results from Ball bearing G3 with updated comp profile:

E85 high mounted externally gated: Maxing out at 365rwkws

I've also done one more run with the The ATRSL25.5G. Little bit pissed as I'm missing 1KWs reaching 400rwkws. Maxed out at 399.1rwkws. Need bigger cams for the full potential of this turbo. Still, this is the highest power ever archived on stock cam from Trent's dyno library.
