01 Audi TT225 compound turbo setup

[DougLoBue]

Wouldn't your overall power be restricted to the flow of the small turbo's exhaust housing?

[Dowski12]

Thats the great thing about this setup even if you are restricted by the small turbos exhaust housing it doesn't really matter. I think Im only going to be running the small turbo somewhere around 17psi which is well under what it can handle. You got to think, the larg turbo is for low pressure, your supplying your smaller turbo (high pressure) with already compressed air where it will then be compressed again and blown into the motor. This is why you can run much higher boost levels. I think we only have to run the large turbo at around 11psi to supply the small turbo with enough pressure to compress it to the pressure we need to make 500hp. I say "I think" because i am not the expert on this stuff. I understand the concept and all but as far as the math goes, thats all my mechanics job. There are a couple of faq sites about compound turbos. They have really good info that is pretty easy to understand until it gets into the math portion of it all. Take a look, they will be able to explain alot better than i can.

Update...FRUSTRATION!!!

The motor hasen't come back from the machine shop yet and i found out yesterday it was because my mechanic never paid the deposit for the work on my motor in the first place(even though i gave him $2000 for engine and powder coat already). So therefore my motor has been sitting there not being worked on for about a month and a half. I called the machine shop yesterday to see what the hold up on it was and low and behold found out i was being screwed. So I called my mechanic and used a few choice words and that seemed to get results.

He went by there today and paid the deposit so hopefully it will be done by the end of this week. I will be sure to keep you guys posted as soon as there is some progress.

Wow that's a bummer. I hope things go better from here on out! Too often it seems like things that start badly also end badly...

[Dowski12]

Well hopefully things start moving forward a little better. After speaking with my mechanic he seems to be back on track. Over the last month I've only talked to him a couple of times about my car, but since our little discussion yesterday, hes been blowing up my phone. So I dont see any problems with things not getting accomplished on his end once the motor comes back. Their moving into a new shop in the next couple of weeks, so he would like to get it done before then.

[01ttgt28]

Nice it always helps if you flash a couple more thousand in his face

[Dowski12]

I should do that...loan me a couple, Im good for it

I did get a new intercooler. Its a treadstone TR1035

any more updates?!?!

[Dowski12]

Sorry nothing really to report yet. The machinist finally started on my motor last Thursday so if he dosent run into any complications then it should be back to the shop near the end of this week. Then the real fun should begin...I'll keep you guys posted.

[Dowski12]

Good news fellas!!! Block will be back on Monday
Im taking the day off to go help with the install so I will try and take some pics of everything as it happens.

[Marcus_Aurelius]

[Dowski12]

Didn't get a chance to take pictures of the motor yet. Should be back in the car tomorrow but i did snap one of my newly powder coated SEM intake manifold, LOOKS AMAZING!!!

[Dowski12]

Got some last minute parts in today.

Aeromotive Adjustable FPR

Aeromotive Fuel Pressure Guage

42DD MAP Sensor Flange

[Dowski12]

After two and half months, here it is. Taken right after delievery so its sitting on a tire on the floor.

[ejg3855]

been waiting for this build to get going.

[Dowski12]

Your tellin me. I was over there today helping install the motor. Got the mounts in and was lowering it into the car when I had to leave. Should be in by now though so now we can start with the fun stuff.

[01ttgt28]

Now where talking lets see what happens

[Dowski12]

Clutch, Friction Plate and Tranny installed. Motor is in but it was too dark to take pictures.

[Chuckmeister87]

Me gusta the power. Post any engine pic please


EDIT: Sorry, engine pic WITH turbos

[l88m22vette]

Talk about perspective, the quattro 02m is huge, almost the size of the engine

...now get to bolting stuff on, good luck

[Dowski12]

Haha...JC, my mechanic said the same thing. The O2M is huge in relation to the motor, and its a heavy beast. The motor looks so different in the car without all the emissions bs. Talk about loads more room and all for nothing. All that extra space is now going to turbos and piping...well worth it, I HOPE!

[Dowski12]

By the way, anyone looking for 225Q parts, I got plenty for sale. If anyone wants them, Im letting them go for cheap, including my old FMIC and upgraded K04. Let me know and I will send you some picks of anything you want.

What kind of ko4??

[Dowski12]

Its a K04-22 but its been ported out It was only on my car for about 4 months and Im not gonna say I didn't give it some gas here and there but there is no shaft play. I wasn't sure if there was really any difference between mine and a regular K04 but I had my turbo guy check it out and he said its deffinitley been modified.

[musTTache]

Im glued.

Send me a PM with prices on your FMIC and turbo.

[Dowski12]

PM sent.

Got some more of the poweder coat back. The vlave cover didn't turn out as nice as the SEM. I haven't seen it first hand but if its not up to my standards ill just take it in to get redone when I take my wheels. Im tired of waiting so I can live with it for now.

Also got my black PTP turbo blankets and black heat wrap in the mail today. Ill have pics of everything thus far this weekend.

[Dowski12]

Bolted on the valve cover and SEM manifold. Turbos will be back from powder coat tonight and starting the layout on monday. Stay tuned




Dont mind the stock fuel rail, just plugging the injector ports till we get the custom rail finished.

[Chuckmeister87]

Ask and you shall recieve. Bolted on the valve cover and SEM manifold. Turbos will be back from powder coat tonight and starting the layout on monday. Stay tuned

Looks nice. Me gusta

Can't see the turbos with the engine in the bay, even if they WERE on...
Need a photo with it out and the turbos on plz

[Dowski12]

Turbos arent in yet. Im going over there tomorrow morning to decide on the layout of where we are going to mount them. JC wants to either put both behind the motor or both on the driver side of the motor. I want one top mounted behind the motor and one on the drivers side. I have final say so we will throw the turbos in tormorrow in different configurations to figure out which works best.

[Dowski12]

Went to the shop today, Intercooler is mounted. We had to trash the crash bar and we might have to trim the bumper, not sure yet.

[lite1979]

We had to trash the crash bar and we might have to trim the bumper, not sure yet.

So is your rad support the only thing connecting the left and right up front now, or do you still have the old IC pipe on the bottom providing support?

[Dowski12]

That transition pipe between the old SMIC's is long gone. We left the mounts for the crash bar connected. Thats what we used for the FMIC supports. We ground the ends off and then welded some thick metal L brackets to it and drilled two holes to connect to the IC, worked out pretty good. So basically yeah, the radiator support is the only thing upfront now. I figure if I wreck in my car I'll probably be doing something extremely stupid, at an excellerated rate of speed and that wimpy crash bar isn't gonna save anything anyway
