Never tried it myself, but heard pressurizing the inlet track with a compressor can get good results. Crank the reg down so that the hissing from the hose isn't louder then the potential leak, and as Nismoid said, jiggle all the big hoses, pipes, listening carefully. Good luck

As you've found out, i doubt it would effect the performance, but would take it back regardless. nice

Some ppl whinge the AVC-R is no good; hard to get stable boost when bleeding a large amount (low wastgate spring tension, high desired boost level) but as with most things, i believe you need to find someone with good experience in the EBC you do choose, (or be willing to ask lots of Q:'s and really research their setup if doing so yourself) ... much the same as a ECU. Going by your wording, im assuming you don’t feel like spending a lot of time setting up a Gizmo or a Jaycar unit yourself The dual solenoid unit Blitz SBC IDIII seems to be the flavour atm, the unit without the screen is a lot cheaper. Profec, AVC-R should all suit your need fine providing you have someone that can set them up properly.

- Paper clip end to keep the flap open and a some tweezers? - Roll car over and shake vigorously? Maybe you'll have to pull the trim off and remove the barrel. Good luck man

Hey Disco, sorry, my question was meant to be non straightforward I'm not convinced by your argument that larger capacity, less often slugs of gas (from a I4) are more effective to moving a turbine then smaller capacity, more often slugs (same capacity I6) I cannot think of any reasoning either way, so am interested in how you get yours Cheers

This may help... i too had a quality photo and drastic fear... http://www.skylinesaustralia.com/forums/t185893.html

^^ The new 997 Turbo has a clutch based torque control to the front wheels as per... "Featuring PTM (Porsche Traction Management) the new system incorporates a clutch-based system which varies the amount of torque to the front wheels, regardless of wheel slip front and rear. This, according to Porsche, aids traction and the handling by redirecting the torque to control oversteer or understeer, thus resulting in far more neutral handling, as well as greatly improved performance in all weather conditions (as opposed to older AWD system which gave the Turbo stability under hard acceleration)" Porsche claim 100ms time for to modulate power to the front. Transfer case, hydraulic ram and pivot fork look familiar

^^ Not getting 100% throttle movement, thats awesome LOL (no offense)

As a refrence, my Trust PEII made 94, which is verrry quiet. I doubt strongly a cop will ping you for 94db.

PEII, well made, insanely quiet. EDIT: I'm referring to PE "Power Evolution"

The man runs Defi's Its not really about "cost of install" there are some complexities. There’s a lot of debate about the best units in the pro tuning world it seems. Iv heard first hand many deficiencies with less developed units like the Tech Edge, which don't cope with altitude change well, and are a little slow in response. If your really keen, at a minimum starting looking http://www.innovatemotorsports.com/products.php Look around though, you can pick up some good second hand deals. A mate picked up a LM1 for under $800. Tested response with $5000 unit; sensor still seemed fine. You mention permanent install? Keep in mind the sensor needs a constant power supply to stop the pump cell from coking up. Others use the setups from Haltech, Autronic etc, which I believe are rebadged LM-1’s and another who’s name evades me atm. Gauge isn't going to help you with a oil leak

Did the stocking help? One would think if you route more air to it, more dust will get on it

+1 Seized PCV valve. Secure the dipstick with a spring like all the cool kids

Billet use custom cores with turbines / compressors from other turbo's, theres dozens of different combos of the Z-P, are you aware what setup your mate had? As in, are you saying his Z-P with a 1.06 spooled 200rpm earlier then a GT35r with a 1.06 rear? Would be very interested to know, ta

Well the thread creation was kinda silly and theoretical anyway (no offense Rick) What better time to get into a boundary effect, fluid dynamics discussion

I was under the impression people were talking best example, as in, if you could choose what was actually happening

Outa interest, does anyone know why the Z-tune is banned?

Gday, Ups to your dad, nice work! Though theres no doubt bit of extra turbulence helps at low rpm with economy. Its if it's warranted on forced induction motors at the expense of power / det at high revs.

I sure do know your fiendish obsession with TS Trying to provoke some counter thought here. You speak of the pulse phases in I4 and I6, but end it with “less time for the next and last cylinder to interfere with its induction and blow down phases” Is this to say turbo V12 and such aren’t efficient? Can one quantify when pulses occur too rapidly and start blowning down, or weakening others, would single pulses per 360 be optimum? HR31DRFT - You've blown 3 of them? Damm, they must be sh_t!!

Cool, we all agreence then hahaha. Laminar flow everywhere is wanted in a performance environment, as designing for turbulence at low speeds at the sacrifice of high rpm power is for gurls. Disco - do you really think though that simple intake valve alterations are the biggest determintor manufactures use to promote swirl? I still would have though it to be chamber / piston design; keeping in mind too much swirl at high speeds cause the charge to reach super sonic speeds and increases chance of uncontrolled ignition.

I’m no engineer, but i would have thought large scale turbulence anywhere would increase pumping losses regardless, its just the stronger and more complete mixture burn from a thoroughly even mixture of fuel and air negates this loss. Some are assuming the only cause and assister of turbulence in the chamber is the inertia of it entering past the intake valves. The act of the chamber floor (piston top) going through BDC and then squashing the charge against the head chamber itself, creates the more substantial eddy currents (swirling from centre to outside) I believe. Due to laminar skin friction, the pressure front caused by the piston is centred in the middle, it hits the spark plug and flows outwards (like a outwardly flowing vortex in a smoke ring) I saw a video when I was a kid of glass cylindered combustion motor that BMW made. Watching the combustion of this vortex of fuel and air was quiet beautiful. With the above in mind, turbo motors with 1.7bar boost levels and fuel at over almost 70psi rail pressure don’t need excess turbulence, the nature of high RPM air speeds, boost and the turbulent effect of in chamber mixture compression does this for us. Added turbulence through swirl inducers and phased intake valve opening is clearly to aid tumble and roll at low air speeds. Manufactures do it for emissions mostly, hence why id suggest in the in high performance world, inducing turbulence isn’t really needed (when in comparison to the negative effect it could have at higher engine speeds) Sticking to the high performance at high engine speeds theme, full blow turbulence isn’t required in an intercooler as the natural resultant increase of surface areas when the intake charge goes down each intercooler runner is enough. Iv personally seen a fair few different variances of “in runner” turbulators. I think it was the TX5 turbo which had quiet evasive and restricting looking little devices. I would think there would be a pretty clear weighting in of “Turbulence at low air speeds for increased heat transfer VS Increased drag at high airspeeds” On a final thought, remember surface irregularities can be used to reduce friction and increase flow over a surface. The dimples in golf balls, and knives use this. Eddy producing dimples can also increase heat transfer measurements without the large expectant increase in drag as per >> http://pdf.aiaa.org/preview/CDReadyMCFD03_...PV2003_3964.pdf All my morning cents gone

They were / still are popular because you can weld to small OEM ones together. S4 RX7 cores etc.

...

In fine state of Canberra, you can have all the gear in, just not connected to the bottle

This thread is funny
