Actually the only options right now are the Vargas Stage 2 DBB and the PFT stage 1. Very little real world numbers on either one, but the first was about 100whp gain and the 2nd 45whp. I would like to see more numbers, but we really only have 1 dyno of each one right now.

As we know their is no N55 @ 500WHP.
Just read on a different thread what VTT meant by 500-550whp.

He meant turbo upgrade will SUPPORT 500-550whp and not actual gains with current N55 FBO / Tune setups.

The marketing statement relative to the actual truth all seems a bit blurry. When asked about the statement he chose to ignore it and threatened to have posts removed.

Read it again. The "wheel combination" will support 500-550whp. That means the compressor and turbine wheel combination he is using is capable of developing that kind of power in thier native housings. What happens when you shove them into housings they were not designed for?

That's the equivalent of me pointing to an GM LS engine sitting on my garage floor that is known to develop 500 crank horsepower and state universally that it is capable of 10-second quarter mile times. In a light weight Camaro with slicks, it would absolutely run 10's all day long. When I drop the same motor into a 1-ton 8,000 lbs. dually it won't even come close to 10-second quarter mile times. Is it still a 10-second motor?

You make a very good point about potential and an additionally good point about how marketing can be misleading. I have seen numerous vender post falling into this category.

However, I do find the language to be straight forward regarding the turbo upgrades. As you said in your analogy, a LS engine in an 8,000 lbs truck won't do 10s...

This turbo when under utilized (even in "Dr N55" car) will come short of "500-550". Dr N55 is nearly 480 now. Likewise u drop the LS motor in the truck or this turbo upgrade into a stock N55 is it still doing 10s???

Perhaps with fuel pump upgrades it'll do 500... The point is this product will not be the rate limiting factor. Understand as a consumer that 500-550 was an estimation made prior to installation and testing of this turbo... which isn't a conservative approximation but nonetheless a pretty good guess, relatively speaking.

The proper way to do this turbo upgrade was to fabricate a different exhaust manifold that can then fit and be properly used to it potential instead of these stock appearing turbo upgrades.

The clear issue with spending $3500 on a stage 2 vtt upgrade is what fuel I got to use in order to get a fbo n55 to 450hp.

Proportionally to other v6 turbo engines on different platforms are easily doing those numbers on strictly pump gas (93) and meth. No e85 and if they really want to liven it up they put in e85 and let loose.

Turbos are turbos. The theory doesnt change neither does physics. Thats why im interested to see what PTF comes up with. And id like to see siginificant numerous dyno runs to prove the numbers are easily attainable and on pump 93 and meth or just pump 93.

Terry tried to get more out of it. He tried 3 more psi of boost and got next to nothing. He tried pushing past that and the turbo that was supposed to be easily capable of 25 psi and beyond is not. This turbo cannot flow enough to make the power. It's not an issue of other parts on the car not allowing it to happen.
Rob Beck and others stated 450-475whp was going to be the limit in these housings. It appears they were correct. Probably also why RB is taking a different path on his offering for the N55.

Agreed, the stock housings are just too small to be efficient flowing that much air. It is probably at or close to a choke point. I was planning to port my scrolls slightly before I sent them in. It shouldn't take much to raise that choke point up another 30hp.

Good point, this is a big limitation. I hope we'll have a less restrictive manifold and largert housing option soon... awaiting PTF option.

Any updates on either turbo options??

We have shipped close to 30 stage 2 upgrades around the world, hold the N55 power and 1/4 mile records. RB, still in "R&D", with no ETA.

We are working on a hybrid as well. We expect testing and availability around the end of the year.

Thanks

Any idea on pricing??

We haven't finalized pricing. Somewhere around the $2500 mark plus core deposit most likely.

As mentioned in our other post: Customers enjoying our N55 PURE Stage 1 will receive 100% exchange credit towards their N55 PURE Stage 2 when they are ready to upgrade.

Thanks

Why on earth would you be posting about your products in a thread about our own and another vendors. If you want to announce things about your products do so in your own thread. Thank you

Why not? It's good to know.

[Rob@RBTurbo]

We have one well underway as well, same $2500 mark as Pure Turbo. Exciting times for the N55!

Tony turbo doesn't sound too excited about the competition...
