BEW, Which Turbo (VNT17, Hybrid, or GT) and Clutch (Daily or Endurance, Dual Mass?)

[burpod]

Are you saying the BEW is suited to higher power? What's the message/point here? And the ALH is?



Vibration? What do you mean? I put a bunch of the turbo options in order of upgrade earlier in the thread. There are some more that can be added. At VNT17 is still a great turbo for a BEW with great mid range punch. I'm just after clearing the discrepancy and that extra low end, high end, and extra 10%!

It cleaned up some questions, and made a few more. Opinions are like bellybuttons but who's belly button to I listen to? Darksides a solid rep tuner vs some dude on the internet? Taking it all in balance. I really like Burpod and IBW's responses...they have alot of experience and several TDIs. Pak and Krook too but I havn't researched their history as much.

Are VNT17 Hybrids still iffy in quality?

I wonder why the BV43 BHW makes so much power? ...almost 200.

I saw some data that said GTDs spool by 2300...

vnt17 hybrids, IMO, at least from vendors such as xman and others (muchboost, powertdi, etc) are perfectly good quality, and boost control *can* be excellent. they're just a little limiting with still having a small vnt-17 turbine. imo, many people probably push them beyond safe/reliable limits. gt18 is at least a bit bigger. the power available <2000rpm even with a gt1852/1856 is likely more than plenty, especially if you have a stock bottom end.

"spooling by 2300" is a very loose term. i have been able to do, without much effort, ~22psi by 1900rpm (forget the exact numbers) with my old gen gt1856. the greatest difference in spool time, torque, smoke, power will be in the tune. almost every boost log i've got my hands on generally shows horrendous boost control, with any turbo lol, especially lower rpm. GTDs should be the best of the best as far as spooling efficiency and otherwise, still, totally dependent on the tuning.... having a stock bottom end and stock head bolts (and not infinite time+money) i'm not terribly interested in trying to make crazy boost/torque at such low rpm.

@burpod is right, vnt17 hybrids can be a good choice, but they can be limiting and can be a bit of a pain to dial in. I know I have a vnt15 with a 56mm compressor wheel and making boost has never been an issue.
I live @4600' elevation and I never run more than 24 PSI boost at Sea Level or at Elevation.
I don't beat on her on a regular basis, I average 40 MPG, and I know I have a boost leak that is killing my FE.
Even with the boost leak @burpod's tune is a real monster. I just had back surgery so I will not be crawling under the Jetta for couple of months to get the boost leak fixed.
I do have a South Bend Daily Driver 2 with a 22 pound flywheel, and have had no trouble with slippage or noise.

Alright, so whilst considering a bigger compressor, mind the surge line. This is a wee bit difficult as the fine folk who have possession of these maps are not releasing them( curse you Garrett ). So examine some of the discussion in the turbo tech database thread. Learn the effects of trim variability...and before that, what it is...LOL There are two basic options on say a GTD2056-something. One if for a Ford, and the other has a larger inducer dia. Back to 'trim' and what this does to a map( reminding y'all we know nothing in detail ). How soon do you want boost and to what magnitude( so to say, delivered pressure ratio ). Taking a 2060 compressor and attempting 2 Bar boost at 2000 rpm is NOT going to happen. That thread has *LOTS of good info to guide you...
