Turbo Upgrade Help
Hey guys. Im having an issue figuring out what to do here. I need to do something about a turbo issue.
I was towing through the south this past weekend, between Tennessee and Ohio, and experienced severe turbo flutter. I was going around 60-65 in OD and going uphill, 12-15 PSI, flutter and loss of power. Kicked it to downshift and up we went. I did some reading and I guess the flutter is a cavitation and can ruin the turbo. Ugh. I have just under 200K on the truck and I can only assume the turbo has never been serviced.
So heres my question: Should I install a 'wicked wheel', a ported turbo intake or just bite the bullet and go 38R?
Also, while having the turbo off, should I do the EBPV delete? What is the advantage of doing this??
Details of my current mods are below vvvvvv Thanks!!

Just my opinion, but I would pull the turbo and rebuild it with either a RR 4/4, WW2 or SPX wheel. Like you mentioned, since you are in there you may as well get some other things done too.
I have all of the following parts on order and will be installing them during the holidays because they are all related to each other or will be easier to install as a whole together.
Just be careful because adding parts and upgrades can get expensive quickly.

Just an FYI, both the blank turbo pedestal and "blank" EBPV delete outlet have much less expensive alternatives. I bought both, in the RotoMaster brand, from RockAuto.
I don't think there is any need to pay for the Garrett name on these parts. With the EBPV delete these 2 pieces are relatively simple aluminum (pedestal) and cast iron (outlet) castings. There just isn't much to screw up, on the manufacturing side.

It seems you should be building 5-10 more PSI before the flutter begins.
I see you have a Bighead and Banks tuner. Is that 12-15 PSI your max boost.
If so, you may simply have a CAC boot that is loose. I had a similar problem, and the sound is strange as pressure builds to the leak point and then bleeds off.

Once it downshifted, it was 22 psi and up the hill we went.
Looking into a new turbo wheel, high flow outlet and ebpv delete. I guess I get to delete a restrictor valve in the flow path as well. Need to do more research.

It sounds like you are experiencing turbo surge, and it is common. If you swap your wheel out with the link below it will take care of it. Or you can go with the a billet wheel for more flow.

No, I max at around 24. I did a check before the trip, as usual, and didnt find anything loose or out of place. All boots intact and no holes. Riff Raff boots are tough as nails.

As soon as the financial situation allows, I'll be doing an upgrade similar to Sous. It is also almost time for a turbo. I really want a 38R, but that is a lot more extensive/expensive for this E99.

Just rebuilt mine with a 360* Kit from Barder. Pretty easy job except for the stupid v-clamp on the back of the turbo. Put a WW2 in and tightened up my wastegate actuator while I was at it. i kept the EBPV because I like the warmup and engine brake funtionality. If I can get another 360k out of it before I have to rebuilt it again, I'll be a happy camper.

No need for a "new" turbo( unless you plan on upgrading), a good compressor wheel should so the trick and as earlier post suggested might as well rebuild it
. I suggest to go and check out spturboost.com perfect customer service and great quality rebuild kits and their prices are real affordable. Speak with Kevin if you have any questions about their kits

I just did mine, I would buy the wheel and rebuild kit from Riff Raff and be done with that part. He has quality stuff.
Now as far as the EBPV. I would keep it. Your in the frozen north like me. It helps with the cold weather warm up. The basics are it plugs the EX and forces hot EX back into the CYL. If you are hell bent on going without. I would grind the rivets off the flapper and remove it. Thus it is disabled and free flowing. You get way more out of a 4" EX than a delete.

I second the Barder recommendation. Great people and great parts.
