U-20ts big turbo build/info thread

[U-20T]

Hi, figured I would introduce myself and start a thread on my 2011 Autobahn.

My background besides the shop and my VW is in mainly JEEPs. My past build was a very custom regular Cherokee. Then I got my Mk4 and finally the Mk6.

I wanted to big turbo the mk4 very bad but decided to upgrade to an Mk6 since it would be new and fresh. I knew I wanted something different so at 6k on the clock the build began.

Details on the car:

2011 GTI Autobahn CBFA, Candy White.

Very Niiiiice (Borat Voice)

Can't wait to see what happens with this! I run through a shit ton of meth with one nozzle, can't imagine how much you run through. When do all the nozzles spray?

 

[corrado917]

Crazy kit,nice i like it.Have you ever dynoed your car?

 

[U-20T]

No dyno yet, Have not really had the time.

As for the meth I am going to be running about a 70% mix and 220ml post IC and 150ml into each runner. So alot

HFS-4 runs off of IDC so it will take some time to get perfect and I can use MAP to to give it a second stage for boost onset. I will also be wiring in the fail safe so if flow drops it will pull boost.

JR is a Good Guy. I had an excellent experience purchasing my Eurojet TBE from him.

Great. My fail safe setting has me feeling very comfortable. Such a great feature.

Whoooooah.....impressive most impressive....

I agree, your eurodyne controller was my second choice. Decided to go aquamist because of the high volume volume of direct port meth. I do wish it was better integated with controlling boost though.

mmm big turbo

 

[U-20T]

Did a little work today, just need to install the tank and pump and wire to the ECU.

 

[zhijjawi10]

Hey JR why isn't that turbo kit on eurojet's website? Is that a new product?

Its actually an old product called the ej400 and was made for the FSI. I used some of the parts from the kit and some of my own stuff to fit it all together.

A few items can be bought upon special request but its no where near a complete kit.
