Let the tinkering begin...

Look at that nasty hose in red touching your airbox...

And the big radiator hose in yellow passing directly under the probe area....



nasty!

Yep, i think its all gotta go

OK, now I know your meaning for "ambient" is different to my undersatnding of "ambient" what you said previously makes perfect sense.

There are some significant heat sources in/near the dashboard (heaters, engines, exhausts, heat from the sun etc), so your dash is probably always at least 2-3 degrees warmer than the outside air temperature (which is what I assumed you were referring to as ambient temp). I should have checked my assumption

No you are right, my comparison isn't strictly "ambient" but this is a "rough" guide, and I'm personally much more interested in finding the hot spots than the exact temps. What I consider ambient is somewhere between the golf display temp, and the "in room" temp on the face of the dash.

Where is the temp probe for the golf display? Under a rear view mirror?

Jay, I was pleased to find today that when returning to a heat soaked car, on a cooler day like today, my inlet temps quickly returned to 1-3 degrees over "ambient". Seems the insulation doesn't trap the heat, and only on 30 plus days does the whole system suffer.

On the weekend I'm going to put it in front of the intercooler at the bottom hose / intercooler junction.

Greg, going to put the GT on the rollers next weekend at Mercury for s**ts and giggles . Will lift the lid on the airbox under full noise, will know then if there's any restriction.

You should come, would be good to see the difference in the curves

[Greg Roles]

Ok, I'm in too. Look forward to scaring everyone with our oilers!
I see a fair bit of restriction in the stock MAF, but airboxes first.....

Edit: Modshack website states 18% restriction in the grid prior to the MAF sensor. This is there to smooth the airflow from the top cover of the airbox, where I figured the "bad" spot was. In my uneducated opinion deleting the 90 degree bend in the airbox lid, and removing the restrictive MAF grid would be good ideas. Certainly my next step. stock MAF's go for $65us on e-bay, so I'll probably get a test mule.

I'd also suggest people out there go for an aftermarket boxed pod like the Mod shack one, rather than frigging with the stock box like I have been. Biggest issue is that 90 degree bend.

Been a quiet week on the dirty hands front, but been spending all my money. This month should be fun
Here's just some of what the nice mailman delivered just today!




On a side note I had my 1500km checkup service yesterday ( not that there was any thing wrong in my opinion ) and I noticed the car was a fair bit more punchy on the drive home. It is breaking traction on boost in the first few gears. Not laying rubber levels, but the traction control is kicking in, and the tyres are chirping a fair bit whereas before it was somewhat smoother and it took uneven road or hills to get the rubber upset.

I'm very happy, but the question is has anyone else noticed this? Perhaps they reflashed it? Mabey a battery disconnect sets the computer back to overfuelling or something? I've e-mailed my contacts at the dealer to ask, but wondered if anyone else has had this experience.

[Jaymz]

Nice, very nice! I want to see it all in there by Saturday

[99gti]

Looking good! Are they an eBay find?

Oooh, nice pressies from the mail man.
More things for me to buy now.
Are you going to do a dyno run before and after fitting all this nice pipework to see what difference it makes.?
Wish i was up there with you guys to see the dyno runs and play together.

On the performance of your car since the checkup.
When i test drove the GT Sport TDI DSG it drove how yours sounds now and really spun the wheels.
Break traction in first few gears no problem at all to the point where i thought **** the tyres arent going to last, this was on a good grippy road.
I really couldnt believe the power of it.
I'll be very interested to know what they tell you they did.

I noticed this after the 15,000km service where the service sheet stated there was an ECU upgrade. exactly the same breaking of traction in 1st, 2nd and 3rd.

[Greg Roles]

Thanks lads, seems it may have been reflashed. Was a very noticable difference. Sweet, just in time for the dyno

Logs, the car is going on stock, so we all have a baseline. My intercooling pipework is a ways off, as my plan is to add two serial water intercoolers to the plumbing either side of the stock air one.

Yeah I know my warranty idea is pretty much snafu now, but I'm having too much fun. If something goes bang, well it's my problem. I can't see any of this unduly stressing the engine and drivetrain, more keep it running optimally and be a bit more responsive, especially on the hot days. I see the big problems arising if and when a chip becomes involved.

The holdup is finding suitable water radiators for the intercoolers. Wait till you see what I have in store there

Yep a universal e-bay intercooler kit, obviously chinese, but looks fine to me. This set pretty much covers 95% of what I need, and cost a massive $168 delivered from the states.
The bar is a 22mm rear H&R from G&C. Quality item!
