No actual point to this post, just thought I'd share, dropping my car off after work and having my RB turbos installed today, hopefully have the car back Thursday and let Jake@PTF work his magic (again).

Time feels like it isn't moving!!

[JStang]

Gotta be an exciting feeling. Once my turbo's go I will likely go this route as well.

[Pr335bob]

Awesome good for you . Let us know how it goes.

[derryck]

You will be very happy especially if you have wastegate rattle on the OEMs. In addition to the power bump the RBs have a more audible whistling sound even just off idle.

[Give_Em_The_DD]

Yeah I'm pretty excited to say the least...I already wish it was Thursday, and I haven't even dropped the car off yet lol

Congrats. RBs are a great option. Enjoying mine for 2.5 years. No issues:

That is what I like to hear! Thanks for the build link as well.

Dropped off last night...now the wait begins...

Just curious what transmissions you RB guys have? 6MT or 6AT?
Eventually when my turbos go I will be going down the RB route as well. I have the 6AT and would be looking to go 550+ whp and whtq so I'm worried about the longevity of my automatic.

Not trying to start a debate about which tranny is better or which can hold more power. I'm just wondering how many 6AT's have been holding 550+ whtq for quite some time and still holding up?
I could always buy the kit to strengthen my 6AT, but that seems like a very complicated DIY or an expensive bill.

[derryck]

My RB car is a 6AT and I run only 93 octane as we don't have ethanol in my area and I don't use meth or nitrous to lower intake temps. I have the Alpina flash and have no issues but I'm not making 550RWHP. I haven't been to the dyno yet but it's running very strong.

[Give_Em_The_DD]

I have an XI and alpina flash as well. I have been using an e-40ish flash from Jake @ PTF which currently has me at 420hp/487tq to the wheels, haven't had any issues yet. Granted I haven't launched the car more than 2-3 times over the last 6 months

First off, if 550WHP is your goal, do a proper turbo swap. The boost and timing curve you'd need to make that power is (imo) overly aggressive with any stock frame/stock manifold solution. Too much heat, too much backpressure.

6AT is unlikely to hold 550WTQ for a long period of time. I make about 480WTQ and my trans is on the way out. With the curve of a single you could preserve it a bit better, but with the way torque comes in from stock frames, it will likely end up smoking the 6AT at the torque levels you desire. 550WTQ is very borderline in that regard.

Dan has the 6AT WR (7xx) and I don't have a clue how his transmission is holding. Some combination of unicorn blood and the relatively gentle curve of a 64mm.

His was holding but he now has to let off between shifts to save it from grenading itself.

Thanks for the advice. My plan for RB's is ~2 years down the road unless my stock turbos go before that, so I've got quite some time to figure it out.
The reason I want a twin turbo set-up is for that immediate torque which the single turbos simply can't offer. I really haven't looked into other issues associated with having 550+whp (like the manifold) but I'll tackle all of that as time closes in.

With my understanding the stock internals will handle the power well so I'm not worried about that as of yet. My best bet is probably to just have the transmission built by Level Ten in NJ.
Apparently its capable of handling ~700 torque after the build. That might not be enough for my longer-term goals though.

Talk to Terry@BMS RE: his experience with LVL10, they did a full build for his E82. Results have otherwise been mixed, and there's an active debate in the community regarding the efficacy of hardware builds when we lack real TCU control. I'll be having LVL10 do a valvebody build/shim this fall in anticipation of the single conversion over the winter.

Yes, the bottom end will handle 550WHP without breaking a sweat. That's no biggie on this motor

Lvl 10 has no proof of that. They were offered a car to prove the claims and were not interested. Take that info how you will.

550whp with RB's is easy... with a nice, fat nitrous shot. Turbine/engine life may vary.

Lol!! Unicorn blood!

True that.

Double true. People get greedy with the hybrid twins and shoot for the moon.

Hybrid turbos fulfill their roles as a PnP turbo upgrade really well. Unfortunately, the goal of 550whp with a set of hybrid turbos is unrealistic. We have hit that mark twice but both times were purely an excersize to test other hardware(built head and Vargas' HPFP setup) and the tuning for both was 100% kill mode. The N54 is VERY stout and has proven to hold together beautifully, but anytime you are running components at the ragged edge(like the turbos would be at that point) and that component fails it's possible for other components to fail as a result.

There will be some awesome options available very soon that will meet you demand for fast spool and make over 550whp without breaking a sweat.

550WHP is too much for upgraded twins to do an a regular basis, maybe for a glory run only.

Agree. My RB's are very happy at about 480whp with 93 octane and meth injection.
