changing the air flow characteristics is the same as moving the compressor map; "to the right" for a larger tubocharger (air pump).. giving you more top end, more air, more air flow.. call it what you will.. and yes there is an increased need for fuel with sustained boost at top end... Air...

It is not clear if you are willing to separate...... the intercooler from the 'package' If so, can you tell me more about it? front mount? dimensions? pics? Thanks...

Assuming fuel type and AFR (wot) remain constant HP = capacity x rpm x boost x ignition advance x ambient air temp x efficiency of intercooler x efficiency of turbocharger.... think about it.. what are you changing when you select a bigger turbocharger... ... EFFICIENCY OF TURBOCHARGER and LAG...

Interesting.. but does not makes sense for what and how I have it setup.. (no biggee) as above... mine is not connected pneumatically... therefore sensing no pressure... I have been using Eboost 1 for years now and Factory ECU chipped / hacked and tuned... Very similar to ECM-link I believe...

Ok.. to determine where the noise is "actually" coming from, I can only think of one solution... Put it on a dyno for the purpose of loading the drivetrain/ engine and associated bearings.... then pinpoint where the noise and vibration is coming from.. Spending an hour on the dyno for...

Things that are coming to mind; Check oil levels in gearbox and transfer case, thinking low oil and or noisy output shaft bearing or bearing/ centre bearing (tailshaft).... Diff whine...? oil level in rear diff..? Process of elimination.. :)

Urr.. it looks like the output shaft seal is weeping... check the level of oil in your transfer case... clean away the sludge/ oil residue as shown and monitor to see how bad the weep/ leak actually is.... as for the noise issue... very hard to call... there are a lot of variables.. when does...

+1... what is this boost solenoid supposed to do....? mine is electrically connected but not pneumatically connected (just looped back on itself)...

I have some figures on record; 4G93T Standard compression ratio (8.5:1) = 180psi across the board (x4) 4G93T Custom build compression ratio (8.0:1) = 160psi across the board (x4) There is obviously something wrong with the motor that your getting 125psi (x4).... have you done a leak down test...

The spring rate in the actuator you use will determine the MINIMUM boost that the turbo will run under full load.... from the point of view when "bleeding" your waste gate actuator, be it mechanically or electronically (e-boost etc).. If your actuator at the moment is set to factory 10psi.. and...

Running E85 with: FIC 850cc injectors, Standard fuel lines, Walbro in-tank, Bosch 044 external, Surge Tank +1 on the bullshit sticks if its said often enough.

Mate! you have my support on this one..!!!!!!!!!!!!!!!!!!!!! Go against the grain!!! This guy wants to do something different.. fuck you who criticise! Dont be SO narrow minded! DUH! Evo or GSR = manual = so what! Evo or GSR usually = 2.0ltr = everyone does that! But is easy to pick on...

2.3 with BIG 16G... ?? isnt that a little small for a 2.3lt? Forged rods says it all! PM me for my max boost with forged rods the sky is the limit.. match ALL of your components up for either response or straight out HP.. you have an amazing platform for MAJOR AWD wheelspin..! pump fuel...

Yeah, Im not interested in doing it, i dont NEED to do it. I work in the Acoustic industry and can and have done proper Exhaust Noise Emission Testing to the Australian Standard and a Report to give to the nice fellows at the DOT who dont test.. They use their "calibrated EAR"... well that was...

this is something i need to investigate.... Brian what do you mean with the 3 year cut off? 3 years in WA or...? I did try changing mine from Qld to WA and I had to go over the pits (be it 4yrs ago)... which is fine.. but the moron told me it was too low and too loud, he didnt even measure...

Have a brand new still in box Wideband O2 sensor XD-16 gauge kit, see pics #3781

Ok then.. Try using a thicker rated oil? a 60 weight....? 70 is generally too thick, even tho I used to run it for years... but high boost meant I blew up one engine using a 70 weight.. by blew up I mean spun a bearing... lol Food for thought only :)

Dare i say it Brian.. But surely the Head has been ruled out by now.. Which leaves the bottom end. Have you put on the oil pressure gauge? Maybe the oil pump hasnt provided enough pressure and what you are hearing is a worn big end bearing? Thinking left field... hows the crank pulley? Is...

urgh... damn memory... lol round pin in centre means non lsd.. as in pic 2 of 2 1st pic...? no pin..? what the.. lol hehe... faaark... cant remember what lsd inner looks like...doh, doh.. i have them... where is that pic when you need it... oh that might be because its late and glenfiddich...

+1 I have 320hp atw with standand cams with "rpw" valve springs on a 93T :blink:
