Mainline Dyno 450 Kw on 98 Octane

This ER34GTT is running a RB25 with a nitto stroker 2.8 kit. 
A Haltech Elite 2500

Just a quick comparison running V Cam Off and On
Boost duty was left the same. 

Pump gas 
450kw on 25psi with VCAM 
and
400kw on 24psi without. 
50KW gain!

Do you mean VCT or V-Cam? I don't belive you can have V-Cam with billet cam covers

It’s VCT/RB25. It’s not a Subaru sprocket that vcam uses.

Twicked this turbo alittle bit, Made same power, picked up another 500RPM of response and 100kws in mid range at same boost level or 23psi, still running out fuel even with an extra pump.  I think the original version of SS3Pro would peek 70kws more at full capacity.

Time for an update to the shit box, this time with bigger and badder dose pipe for you dose bitches. Nearly 3 years in the making too :D

407kW @ 2bar -> 1.8bar  on E85. Mainline AWD dyno, with 16kph/sec ramp rate.

Mods:

  • Garrett GTX3576R Gen 2
  • Garrett T3 1.01 divided rear housing
  • Turbosmart Gen V 50mm
  • Sinco T3 twinscroll, single gate manifold (pulses split to the gate seat)
  • 3.5" Turbo back with 5" body Venom Cat, 2x Mufflers
  • Generic built RB25DET NEO motor
  • Spool billet oil pump gears
  • Tomei 260/9.15 Poncams
  • 80lb Valve Springs & Ti Retainers by Performance Springs
  • HDi Hybrid 76mm eBay FMIC (holding back the power)

With high IATs air density is dropping, thus boost is bleeding off as well with small DC corrections on the boost DC table. I did order a Plazmaman Pro cooler but it didn't arrive on time. IAT peaked at 57 degrees C in a dyno room with an ambient temp of 19 degrees C. From the data, reducing the IAT will improve the boost control up top, get more air into the motor and will yield the results I'm after.

Once the FMIC comes, I'll be back for round 2.

Special Thanks to:

  • Alex at Birrong Automotive for allowing me to use his dyno
  • Adam at Weldspeed for the fabrication work
  • Yez Racing for supplying most of the parts

Data, etc. available in my build thread here:

Sorry for the lack of derived RPM, I forgot to set it up, in the Analyse screen it shows you true RPM vs. Power vs. Torque.

Time for an update, same turbo but refreshed motor now with 437.9kW at 1.7bar boost dropping down to 1.5bar towards the redline. Looks like I've maxed out the compressor at this stage. I believe there are some improvements to be had such as venting the gate to atmosphere and deleting the cat.

Will be back to get the closed loop boost control dialled in when I have time. Was a pretty surreal experiencing for me as I've never tuned anything this powerful nor anything that revs this high! Alex said I could safely bring the rev limiter to 8600rpm if I wanted to (which I did lol).

Mods:

  • Garrett GTX3576R Gen 2
  • Garrett T3 1.01 divided rear housing
  • Turbosmart Gen V 50mm
  • Sinco T3 twinscroll, single gate manifold (pulses split to the gate seat)
  • 3.5" Turbo back with 5" body Venom 100 Cell Cat, 2x Mufflers, Gate plumbed back
  • Generic built RB25DET NEO motor (CP Pistons, Manley Rods, Nitto rings, ACL bearings, ARP dis dat, etc.)
  • Spool billet oil pump gears Nitto Oil Pump
  • Tomei 260/9.15 Poncams Kelford 264/272 244-B 
  • 80lb Valve Springs & Ti Retainers by Performance Springs
  • HDi Hybrid 76mm eBay FMIC Plazmaman 76mm Pro Series
  • Plazmaman Intake Manifold
  • ATi Balancer

Below is the log (no idea why SAU makes the thumbnails so damn small now. Ignore the oil pressure, it's reading wrong. I suspect the sensor has the right part number printed on it but it's actually a 5 bar sensor (not 10 bar).

Here's a video my mate recorded of me tuning, you can see I'm constantly looking at Alex to see if I need to abort the run. Previously there was a misfire event that sounded like engine knock from where he was standing. I took out the plugs then gapped them down to 0.4mm and it sure did the trick!

    • Have you not seen geospy.ai? It can now give GPS co ords to within a metre from a photo, even if it's a random photo you take inside. Supposedly at the moment only the government/law enforcement has access to that... Supposedly...
    • I've got the rear ones, they're certainly beefy. I need to take them to my driveshaft guru to check over, he's very fussy about the quality of components so I'll let you know if they are made of cheese by a blind man.   Are you in Australia? A mate just had a set of EN26 shafts made for his K20 Lotus by our fabricator which were quite cheap (compared to Driveshaft Shop) so if you can procure the CV's and draw what you need he'd make them for ~$800 for the pair.
    • Had I known the diff between R32 and R33 suspension I would have R33 suspension. That ship has sailed so I'm doing my best to replicate a drop spindle without spending $4k on a Billet one.
    • OEM suspension starts to bind as soon as the car gets away from stock height. I locked in the caster and camber before cutting off the kingpin. I then let the upright down in a natural (unbound) state before re-attaching it. Now it moves freely in bump and droop relative to the new ride height. My plan is to add GKTech arms before the car is finished so I can dial camber and caster further. It will be fine. This isn't rocket science. Caster looks good, camber is good, upper arm doesn't cause crazy gain and it is now closer to the stock angle and bump steer checks out. Send it.
    • Pay careful attention to the kinematics of that upper arm. The bloody things don't work properly even on a normal stock height R32. Nissan really screwed the pooch on that one. The fixes have included changing the hole locations on the bracket to change the angle of the inner pivot (which was fairly successful but usually makes it impossible to install or remove the arm without unbolting the bracket from the tower, which sucks) and various swivelling upper arm designs. ALL the swivelling upper arm designs that look like a capital I (with serifs) suck. All of them. Some of them are in fact terribly unsafe. Even the best one of them (the old UAS design) shat itself in short order on my car. The only upper arm that works as advertised and is pretty safe is the GKTech one. But it is high maintenance on a street car. I'm guessing that a 600HP car as (stupidly, IMO) low as you are going is not going to be a regular driver. So the maintenance issues on suspension parts are probably not going to be a problem. But you really must make sure that however your fairly drastically modded suspension ends up, that the upper arms swing through an arc that wants to keep the inner and outer bolts parallel. If the outer end travels through an arc that makes that end's bolt want to skew away from parallel with the inner bolt, you will build up enormous binding and compressing forces in the bushes, chew them out and hate life. The suspension compliance can actually be dominated by the bush binding, not the spring rate! It may be the case that even something like the GKTech arm won't work if your suspension kinematics become too weird, courtesy of all the cut and shut going on. Although you at least say there's no binding now, so maybe you're OK. Seeing as you're in the build phase, you could consider using R33/4 type upper arms (either that actual arm, OEM or aftermarket) or any similar wishbone designed to suit your available space, so alleviate the silliness of the R32 design. Then you can locate your inner pivots to provide the correct kinematics (camber gain on compression, etc).
