Tte turbo reference

[Smcknighty]

It's an sp, not a tte. K thanks, I have some fuel cleaner which I think ups the octane, will have a google. I've not driven it aggressively since but it's the only car right now so it will need to be used. Thanks for the advice!

I hope this thread is a proper place for my question:
Have you ever had an overheating problems with your TTE turbo?
I hit hight temp during spring/summer time - my tuner told me that its the inefficient IC fault
Do you know any TTE IC improvements/replacements?

Odd you should say this. Helen's car just got a standalone put on to run the turbo kit (SP240, very similar to tte) and the main comment from the tuner was that intake temperatures were too high. The intercooler isn't sufficient.

I don't know if it's because of the intercooler being old and not functioning as well or something else.

Dan944 has a custom turbo kit and had the same feedback, so he has taken a lot of steps to get temps down.

So I'm not the only one.
But insuficient TTE IC for 240hp is a different story than for 186 hp

Yes it is, but it does indicate that there's not much in the way of headroom. I'm guessing you're not seeing 50+ Dev, but 38-45. Which is still high but tolerable

I need a TTE IC dimensions. Anyone?

@Ardent looked into this and found a company who can supply.

Personally I would convert it to a charge cooler setup.

Hello Hitalin
Bit later than I expected but here goes.
If you go back to page one on this thread you will see the one that I had manufacured and where from.
In terms of your question about overheating. No, never had a TTE overheating problem.
To qualify your question.
Is that in the sense of coolant overheating or too high a desirable induction temp?
What is this high temp you hit?
And what is it your tuner can do that others cannot, as the TTE piggy back ecu, like the stock ecu is non tamperable?

What I can say is, the IC lives in a very hostile enviroment and the original IC was in a very poor state. (cira 50k miles) I would suggest that 1/3rd of the vents vanes whatever you call them where, blocked or damaged or both. And mine was leaking boost as had a hole in it where it had worn through from grounding or otherwise. Before my ownership.

Have you closely inspected you IC?

As above, if you go to page 1, you will find who made mine. In terms or dimensions, they made a perfect replica of the original.
They kept the dims for future production. Maybe give them a call.
I still have my original schweizer IC but given the angles involved any dims I could give, would be a bit rough.

[Ardent]

Hopefully, rather than D/sizing etc and posting here, pics should be here.

It's me-Hitalin (Strange that I have two different acc-one on Tapatalk, other via internet site.

1. I have very high intake temp. Don't have the numbers but my tuner told me that I can't go any higher than stock 186 hp without cooling the intake. During the summer time my car is slower - I can feel it as the outside temp rises.

2. I checked the company you mentioned on 1 st page. They don't have TTE IC dimensions in their archives. That is why I asked for them.

3. My turbo kit is a TTE replica. Same turbocharger/ air filter / IC and fan but different exhaust manifold and piggyback. PB is fully adjustable - that is why my tuner can improve my set up

I started improving my IC. First try - IC from Audi B6. Hope it helps. It's that big

Very good find! Let us know how it goes. It looks like a good candidate

It's very cheap and quite easy to fit. I do some tests on Monday and share results

Keep an eye on the join between the plastic tanks and the Metal core, they have a tendancey to seperate if you put too much boost through them

Ah yes. I remember that being an issue on the tfsi blocks. A lot of people swapped to full alloy radiators. But boost levels on those are far higher than those we run on our 2s

The third post in this thread by s12vea shows the TTE manual, including the piggy back unit. Here are some actual pics of the piggy back ECU and cabling/tubing. Also shows where TTE teed off from the VSV.  I see TTE made an extra hole in the firewall and installed a grommet for the vacuumline going to the VSV and the wiring for the decklid fan.

I suppose I could tee off a tube for my boost gauge from the piggy back tube. Anyone else done a boost gauge install that way?

[shnazzle]

When we had the SP240, it had a T exactly there for what I assume was a boost gauge before we got it. 
Eventually we did plumb a boost gauge into it. It worked.

[s12vea]

Yes I Used that feed for boost gauge also

[Bugster_MR2]

Thanks guys. Installed the gauge now. Seeing around 9 psi at WOT in 3rd which is around 0,6bar. Should be around TTE spec afaik.

[Ardent]

9psi sounds about right for tte

[s12vea]

Bang on the money

[Bugster_MR2]

Did anyone of you change the stock silencer with a free flowing one? How does it affect boost and/or the engine management? Maybe not at all since the stock cat is the worst bottleneck?

@Ardent @s12vea

[s12vea]

The cat is the first bottle neck so might be worth looking for sports cat or decat. I used a spacer on the sensor and never had any issue with engine management light throwing p420.
If you have a turbo it would be a shame to not have an updated backbox. The stock / tte should be fine to 220/230 which will be fine for tte setup
