    Happy New Year ppl

     

    Got myself in a bit of a mess. Can't fund a new 350Z DBW pedal locally so sort of stuck with what the next best option is. Want to ensure pedal position is at least as  good for heel-toe as factory

     

    Measured up the std inlet and seems I need to make do with 400rwkws through a 60mm DBW Bosch throttle body

    Yeh,  I found a place that does 68 vane 343mm rotors so hoping going from 42 to 68 with some better ducting will keep them alive

     

    For all those reasons I have kept the 17s Uncle Dunc....32s just don't look as good with 18s. But the 343mm does limit the 17" wheels you can run to basically LM GT4, TE37s or Weds TC

    You Bathursting this year?

    I run RB25DE inlet manifold on an RB25 (no VCT) with twin 2860-5s on E85 and it is more respo lnsive then generally the R32R33 GTRs with same turbo setups in same dyno. Whether it's cam timing or other things RB26 inlets keep pulling at 8,000rpm where I have found on two different setupa the long runners start fall over

     

    To the point...I reckon I'll listen to a mate and try one of these on the spare motor

    Of course. Never getting rid of the old girl. Sandown went well yeterday. Definitely need some new tyres as they are rather square now :)

    PB with a 1:19.77

    Not happy with the 4.1 diff and need to go back to 4.3 ratio. But good to be consitently getting some laps in the car as I still suck

    So whats the thinking on the plenum? Very different type of comparison but i lost torque and response on my 310rwkw RB20. So i was going to RB26 plenum my 2.8L Neo build. Easier to run a plazmaman or even std. My Kinder Surprise RB25DE with no VCT beats RB26 on same dyno, fuel and turbos and can only put that down to the long runner inlet. 

    Does the torque mapping mean you have what you can use so plenum isnt as critical? Thats assuming its not bettercat response power and torque which may have been your experience

    I'm too big a tight ass to do anything ECU wise. Power FC gets the job done. By the time I do an ECU. Loom, trigger etc it's 5k that doesn't make the car any faster as I really don't need more hp.

     

    I'll pull the loom from the car and strip the loom this weekend . Also need to do a fre checks on the engine. Doing a hot shut-down at Griffins Bend wasn't ideal. Lifters were loud and engine  a bit cranky when I got it fired back up the next day

    So after being ready with a week to spare before Bathurst, the car developed an oil leak that took 3 days to diagnose  Tried lines, gaskets and in the end it was a hairline crack in the alloy housing that bolts to the block that you screw your filter too. Was a bastard to diagnose. LOL , may need to make a longer oil cooler line and install one of those billet ones.

    Then on to Bathurst. Car was running like a dream. First 3 sessions were either red flagged 2-3 laps in or just too much traffic and was forced to clear the slower cars until the re-categorised starting positions on the dummy grid. For session 4 they bumped me up 18 spots right behind a Cup Car on slicks. Was pumped and was hoping to finally get a good run without traffic.

    On the first flying lap at the top of Mountain Straight the engine went flat and had no drive at turn in to Griffins Bend so had to do a Glen Seton 1995 and pull over in the gap in the concrete wall on the right to the end of the session.

    So lost injectors for some reason so started pulling back all the loom tape trying to find the short. Couldnt see anything , so called it at 9.30pm and went for beers.  In the morning re-taped the loom and had injectors back!!!!  I hate it when things start working for no reason...I hate it more than when they stop for no reason :)

    So waited to the afternoon session, spoke to drivers around me to make sure that I could find a gap and tried my luck for a single lap.  LOL i am guessing it was a combination of heat, vibration etc that something is shorting and popping the Engine Con fuse so with very few plces to pull off the track and too many walls to be losing drive and power steering etc only wasnted to do one flying lap

     

    So this is the vid of that lap that ended up as a PB...sooooo much left in it. Will have to go back next year after i put a new loom in the old girl over Xmas

     

    Even though the morning 3 sessions were red flagged etc the running around with Porsches and big HP Evos was the most fun I have ever had in the old girl
