Default Another 17/22 with related plumbing goes in

Some pics from my efforts last couple of days. I put in the 17/22, the OMI pipe, the lower IC pipes and the PD150 intake with an SRP. Saved the oil line no prob with Herm TDI tool idea - Just cut a 2 notch slot in the 12pt 17mm wrench.

Well, took it for a test drive and I lost all smoke, some slight additional power. Turbo gives a solid feel though. I am maxing out at 20psi on gauge with WOT in 5th. I guess I need the 3bar map and more fuel (running rc3 and sprint 520 at the moment). Thanks for the great folks advice on this forum as usual. For now how much can I go down on the IQ to get a bit more fuel?

Looks good... What did you have to do to get the faux-EGR setup? What parts and where did you source them? I'd like to upgrade to the PD150 intake but I emissions test in my area. A functioning (or apparently functioning) EGR is a must have for me. You'll love the turbo... now it's time for bigger nozzles, 3 bar MAP and a retune...

Thanks. The Yorkshireman on this forum 'ryanp' vendor out of UK. He has tons of PD150 intakes. He included the matching EGR which I honed out like Wingnut's SRP.

For removing the oil line, doesn't it work if you just use two open 17mm wrenches? Why do you need to use the box end?

It's a 2 pc. fitting w/a flare adapter threaded into the manifold. When you try and loosen the top flare nut only, both the adapter and the flare nut want to turn together. You have to sneak in there with a 17mm and hold the bottom adapter to keep it from turning. It's buried in a small area that doesn't allow a full sized 17mm open end to grap the flats of the adapter. Most just grind down a 17mm open end and hope the flats are aligned in such a way that you can get to them by inserting the wrench the one and only way it can get in there.

RC4 with 3 bar MAP is the way to go.

Feel free to bump the IQ down to 2.0 for more fuel. I wouldn't go below that. I've heard pumps can run away below 1.

At 2 mg/R he's probably going to suffer from the dreaded SDS (Slow Down Shudder). Every car is different and he may be OK. Go ahead and ramp your fueling up and see what happens. Ultimately, the tuning is going to spell out your maximum fuel per stroke but until you get or decide to get a re-tune, give 'er some more juice and see what happens.

2 may be OK. The shudder seems much more prevalent in '99.5s and '00s. Setup looks nice. Bigger nozzles will help. PP502s may be a good middle-of-the road choice. That's what I'm running with a 10mm pump and RC6.

Hey, how'd you get your hands on RC6... When I was negotiating w/Jeff on tunes, he was discouraging the use of RC6... too may internals scattered about the landscape apparently. Well, for those fortunate few, it indeed looks like their tune goes to '11'...

I was one of the first, and I've had to keep him away from my ECU so he won't take it out. I've got about 40K on the car with it, no internals flying around yet. And I've used it pretty heavily on the track. Shift when the tach stops, or a bit after.

On that, we are alike. Amazing difference up top w/RC5 compared to RC3... Enjoy!!

Jeff actually says RC5 is good to 5500, and also says that RC5 is stronger in the midrange because all the maps are stretched out to work with RC6. I may go back to RC5 on the ALH base maps so I can pass inspection this year.

I've never really tried to approach 6k, I just know it doesn't stop @ 5500... That pesky rev-limiter somehow disappeared on me. I don't really want/need/miss having RC6. Except for a few niggles, I've been pretty happy just where I'm at. I do need to give you a call though and pick up a few supporting goodies. Such is the way when owning a modified TDI...
