The New Official S A U - N S W Spotted Thread
Dose Pipe Sutututu replied to GoldZilla's topic in New South Wales
Heya!Cracked the gate because couldn't high beam lol Also spotted GO44IT? R33 S2 super clean and shiny coming down my street! -
Series 1 uses 1x plug Series 2 uses 2x plugs - also has a different TPS In terms of number of wires.. can't remember lol

Turbo Flutter/plumb Back
Dose Pipe Sutututu replied to BatmanBarrie's topic in Engines & Forced Induction
^ why is that each time I put in the word "tttuuurrrkeyyy" it gets replaced with rubbish? lol Flutters are sick.. if you don't like it - put a stock airbox on.. then when you're bored back off it goes -
Turbo Flutter/plumb Back
Dose Pipe Sutututu replied to BatmanBarrie's topic in Engines & Forced Induction
meh.. I run 1.5bar and it flutters like a bunch of wild the sphincter of the universes under the bonnet.. yet to see a turbo explode -
Wasted so much time taking photos of them and pulling them out of boxes, sigh

It's because you're still running your stock water/oil heat exchanger My oil temp probe is in the sandwich/thermostat plate If you ever see guys with RB20s with massive oil cooler without thermostats - their oil takes ages to heat up.... (I for one did the same thing on my RB20 back a decade ago, ran an oil cooler without a thermostat - very silly).

it's where the oil filter sits on.. you'll see water hoses going in/out of it

Anyone used Siemens Deka V injectors? they come in "short" length, i.e. 48mm end to end OR 35mm O-ring to O-ring? They seem to be pretty good based on these tests: http://racetronix.com/product/Injectors/FI114700_Brochure.pdf I've been trying to redo my injector needs by finding a cheaper alternative (yes I'm being cheap, but I can't envisage spending $1.2k+ on stuff when the motor cost the same price)

#@hypergear - with constant variable timing this is where it gets really fun/confusing as the cam timing varies over RPM & LOAD, i.e. MAP Ignoring the duty cycle settings (determines how much duty is required to shift the cam actuator) & and the controller gains (closed loop calculations P = proportion gain at present correction, I = Integral gain past correction, D = derivative gain future correction) VVT1 = Intake Cam VVT2 = Exhaust Cam VVT1 = uses Fuel 2 table to set the angle, which is depending on RPM & MAP - this makes it 3 dimensional, that being (RPM, MAP and angle of advance/retard).. so as MAP increases and/or RPM increases the timing changes. If you click Target Angles it will take you directly to Fuel 2 table.. please note the values showing in there are not fuel correction values. VVT2 = uses just a standard RPM table, there's only 2 dimensions in there.. that being the RPM and the angle of advance/retard of the cam Unfortunately I've never tuned cars with varying cam timing so I can't input too much here.. I've always worked with Nissan's dinosaur on/off timing (which makes tuning much easier too) But I can imagine as RPM increases you would want the advance on the intake to decay i.e. retard, however at the same time you want to advance the exhaust cam as RPM increases to promote more air being "pumped".

From A 290Rwkw R34Gtt To An Evo 7-9
Dose Pipe Sutututu replied to rondofj's topic in Engines & Forced Induction
EVO, handling performance and newer really -
long story short, dyno a tuning tool to safely determine max torque and load up the motor without snapping out sideways and getting pulled over by cops. Want to test power? go do a quarter mile.. that never lies (technical constraints apply, such as: tyres, weather, surface temperature, driver ability, not getting kicked off the track because you ran a 10, etc.)

From A 290Rwkw R34Gtt To An Evo 7-9

If I was given a choice of a worked GT-t OR a mild EVO.. I know what I would go for -
From A 290Rwkw R34Gtt To An Evo 7-9
Dose Pipe Sutututu replied to rondofj's topic in Engines & Forced Induction
yup, another reason I own a R33 GTS-t with rust and 500000+ kms with a dash that says 143000km LOL Wonder which dealer hairdressed the car -
^ dyno wars lol.. that's what he meant Maybe the previous operator ran it in 4th and maybe this one ran it in 5th (being a R34 GT-R, 5th gear is 1:1 as it's a 6 speed).

From A 290Rwkw R34Gtt To An Evo 7-9
Dose Pipe Sutututu replied to rondofj's topic in Engines & Forced Induction
^ well said but then there are the best of both worlds in a C63 AMG, E63 AMG, etc.. of course you could buy 15 GT-t with that money or 30 with the latter vehicle. -
of course, e-mail me all your questions and I shall answer .. Long story short with VTC enabled you produce more torque due to higher cylinder pressure thus the motor can only take less timing, as soon as it disengages torque will drop off - reducing cylinder pressure allowing you to ramp up timing again. From my limited tuning experience, motors with a shorter stroke will prefer a mild ignition ramp after peak torque, where as a longer stroke motor i.e. SR OR 4G likes loads of timing hammered into it after peak torque. Best way to determine where to disengage VTC... setup a mild timing map with VTC on a few thousand RPM past peak torque ~6500rpm (of course monitoring knock) do a dyno run, then set the VTC point around 4500rpm do another run.. Overlay the two torque curves and you will see your optimum VTC disengagement point. Of course after you do that, you can start ramping more timing after VTC disengagement and tune for power up top. That's a quick run down of it. Just a note, I've never worked with variable cam timing and variable lift.. RBs and SRs use a fixed on and off point which makes tuning easy for an amateur like me. In terms of injection, VE is closely related to torque.. more torque higher VE so it's natural you see your VE decline as your torque drops off.. this is the beauty of VE tuning.. makes tuning easier

Expensive lesson I have admit they suck and taken my learnings and documented it on nissansilvia.com

They probably used a bigger drill bit and it's causing all the issues. Also the spray pattern looks like ass, I'm pretty sad I jumped the gun and bought these water pistols.

Mine is always around 5 to 10 degrees cooler than the water temp on normal days. On the track it's usually in sync
