The ones in the first post came with the kit. The 90 degree silicone reducer on the cold side IC outlet wasn't quite tall enough to allow the charge pipe to connect to the intake manifold connection.

I bought this item (http://www.hps-siliconehoses.com/57m...ahdRoCrJXw_wcB) which had excess length on both ends and then trimmed it back to fit.

Note, that hps unit, although it says it's 2.75" on one end ... I think it's a touch smaller. The 90 degree reducer in the kit had no problem going onthe IC outlet. But I had to pre-stretch the hps unit pretty severely before it was willing to slide over the IC outlet.

That also reminds me ... there was one little flat plastic piece on the passenger side under the radiator that I removed (it has snap connectors and then you can slide the thin piece in/out of position) as it was causing a slight interference when raising the IC into position.

it might be smaller amigo tdi but doesnt hv the restrictor the OEM you showed, and DAMN NO RED COLOR wtf LOL!!!!

tdi you think it might be somewhat 2.50 vice 2.75 which I believe is still better than oem

Does anyone think this mod would add to the wastegate issues people are having post tune? I can see this mod being quite beneficial, even if cooling capacity was the same

I think the big end of the HPS unit was more than 2.7 but less than 2.75 ... And it's a very well made and stout multi layer piece of silicone (better than what came with the kit) so it doesn't give much at all. It eventually went on but I had to stretch it a bit on various other things first (like a propane cylinder with increasing amounts of duct tape wrapped around the end ...).

I doubt it.. That issue is; drive pressure vs back pressure .. All exhaust side not intake

As an FYI, the little plastic piece appears to be #8 here: http://www.realoem.com/bmw/showparts...18&hg=17&fg=05

So, I think I understand what you are asking, Just want to make sure you are aware it is the combination of things, including the reduction of exhaust back pressure that is overwhelming the wastegate. If you mean will it make a wastegate/overboost problem worse, yes. If you mean will it cause a wastegate issue, not likely.

Worse, yes. The turbo is interconnected between the exaust and intake (exaust gas is the push for the intake) so if you open up the flow on the intake side, the exhaust turbine should naturally spin faster.

With an external wastegate TDI should still be ok, but less turbo lag must be really nice.

This is something I'm very interested in logging. Unfortunately the weather has not been cooperating with the times I have had available to do some "TestO-ing"...

Some data. Looks like the internal and external waste gates working together have no issue controlling boost with the better flowing intercooler as it looks very similar to previous boost data with the OEM IC.

Hey folks, Pheno and I have been working on some enhancements (I have ideas and he does the hard work - it's a totally unfair situation ). Some of those enhancements should be come out shortly, such as:
-Graphical playback of logging
-Small installation package that includes only required EDIABAS elements
-Calculated 'gauges' like Horsepower and Torque, Brake Specific Fuel Consumption, ect. Essentially, road dyno.

We were thinking it might be best to start a new thread or may be even a sticky, so that everything can be found in one place. That would include tutorials and sample videos.

What's the best way to make this available to anyone who wants to try Testo out or learn more, without searching throught the posts? And does anyone care?

[hand up] I care :-)

Sounds great. A sticky would likely be good. Or even a dedicated thread would be fine with me.

With the size of EWG that TDI has he should be OK for many more mods to go.

What's the butt dyno reading?

[DWR]

Look at those IATs. That's some dense air at 28psi of squeeze - could use some more fuel with that, haha.

Due to butt dyno's being sensitive to placebo effects, I'll refrain from comments until there's some dispassionate data.

[Puerto Rican 335d]

Tdi I just bought a product yesterday for fuel stabilizing I'll get you the tech data and website link either today ot tomorrow so you can look at it, I want to say that the car is actually working smoother and less lag since I put it in I hv put in over 60 miles w it and I beleive it might be to early to say more. i'll open a thread on this stay tuned amigos

You know, using the DPF differential pressure sensor would be the perfect way to measure the pressure drop across an intercooler in our cars ... all it would take is a little npt tapped hole and some barbed fittings on the in/out side and routing some hoses up to that sensor...

Are the pressures for the two events similar enough to both be in the linear range of that sensor?

Yes, I agree (been criticized once or twice for this kind of thinking, so glad you brought it up ). We can use the 'dead' sensors from the alphabet soup delete. But it is better than that! We can use the 'dead' sensor wires and measure anything we want, as long as the signal we are sending matches the output range of the original sensor - and one caveat, that it does not trigger limp mode (I have couple of questions along these lines to a certain well known tuner, but don't have a response.). How about IAT before and after intercooler, before and after H20/meth injection, diff pressure across an air filter...

I did exactly this very same thing when I was involved in tuning an 8 second, ice water intercooled, supercharged V8 Mustang, using the signal lines of emissions sensors in the stock ECU. Even cooler when you start using actuator lines Of course, I could program the ECU then, unlike this frustrating situation.

Absolutely, yes. You might even worry it doesn't have enough resolution, if you get a very free flowing IC.
