how much boost do you want to run on the stock turbos anyway? I run about .9 bar and the stock IC works very well. Inlet temp is pretty well under control.

What sort of inlet temps? I am running 250kW at the rears, power fc and cams on stock turbo and get inlet temps of 40 - 50 degrees :confused:

admittedly this has been more in commuting, have to see how it goes on freeway

What is average?

depends. if I sit in traffic It can quickly get up to 50degrees. then once on the move it's down to around 38. I find once it's gotten up to 50, the ic can't drop it down below around 38. but this may be in part due to the plenum and all the post IC piping being nice and hot. On the track it didn't go above around 35 (from memory). on a 26 degree day, inlet temp (that's in the plenum) of around 10 degrees above ambient is pretty good. I'm sure the plenum and post IC piping is a lot higher than 10 degrees above amb.

one other 'test' I've done is after a thrash put your hand on the inlet tank (VERY hot) but the outlet tank is very cool to touch. it actually feels cooler than ambient.

I guess the only real way to test the IC'c effectiveness is to get three temp sensors. one ambient, one ic inlet, one ic outlet. coupled with the plenum sensor you could tell:

1. how much your turbos heat the air over ambient

2. how effectice the stock cooler is at cooling that air

3. how much heat is transferred into the intake charge between the IC outlet and the throttles.

Went for a strap last night... according to the aircon unit, the ambient temperature was 16.5 degrees. While cruising at 100km/h for ~10 mins the temp on power fc wouldnt drop below 33 degrees. After a quick squirt through 2nd and 3rd gears, the ambient temp wouldnt drop below 38 degrees, and quickly went up to 40 and sat around that the whole way home.

I take it that is 20 - 25 degrees above "ambient" its time for a new cooler? (was running 17psi and made 330rwkw in the same trim as I was driving it last night) :rofl:

Danny if your got std turbos you do not need an intercooler upgrade and as for running more boost through the std turbos JUST DONT it's not worth the risk. As if they let go they can damage the engine, i thought it hog wash till a friend in perth had it happen recently ($10,000 repair bill /motor and turbos) so i would take the money your put a side for intercooler upgrade and buy new turbos, it will be the best thing your ever done.

As i'm running 530rwhp on std cooler quiet happily and the best i think you might get out of std turbo would be in the high 300s

Ps oil in the intercooler means the turbos are passing and are not far away from going bye bye , sent four sets die now(mine included)

cheers

    • The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG has not responded to my emails so far since purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.  
    • There's a good German place in Brisbane if youre up for the drive 😛
    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋
