The Roush Phase One and the Phase Two upgrade kit is a very simple kit, right?
There's only four major components at play here.
The price for the Phase Two upgrade's gonna cost you right around 1,000 bucks, and it's
gonna get a simple two out of three wrenches on the difficulty meter.
So, who is thing gonna be for?
Well, that's an easy one, right?
Anybody that wants to take the Roush TVS Phase One kit to the next level and make more power
using some more boost along with accounting for some fueling and a new tune, thanks to
the included voucher.
More specifically guys, this is gonna take your 670-545 Phase One kit to 727-610 at the
crank, which is a nice little increase in power.
Well, let's break down what the Phase Two upgrade kit really is all about.
And at its core it's got a very simple goal, increasing the boost overall, which will of
course increase your power in the process.
Now obviously, that's a big oversimplification here, but that's what you can expect in a
nutshell, with the Phase Two upgrade.
So, how do you increase the boost with your TVS blower?
Easy.
You change out the larger 85 mm pulley included with the Phase One kit in favor of the smaller
80 mm pulley included with the Phase Two upgrade.
Now, this is gonna effectively raise your boost from 8 or so pounds with that larger
pulley to about 10 or so pounds using the 80 mm option here.
And I say roughly, because there are a couple of factors at play that will change your final
boost numbers ever so slightly, and I'm talking long tooth headers and even the calibration
can play a small role in changing those boost numbers.
Again, very, very slightly, guys.
Now, the nice thing about these pulley changes with the TVS, they're very easy.
Straight up bolt on job here, and the best part is you don't even have to change the
belt out with this pulley swap.
And for those who know and for those who don't know you can't just add more boost without
addressing other key needs with your car, fuel being a biggie here with this particular
application.
So, in order to make the injectors included with the Phase One kit work, Roush does include
their digital Plug-n-Play fuel pump controller, otherwise known as a pump booster or maybe
even a booster pump, with their Phase Two upgrade.
Now, these things are clutched from doing a bigger power build because what it's gonna
do is use your fuel pump that's actually in the tank already, your factory pump, and just
boost and stabilize the signal or the voltage, increasing the flow capabilities in the process.
So, your factory fuel pump is actually capable of more than what it's doing right now in
factory form.
It just needs a little help, and that's where the Plug-n-Play controller comes in.
A lot of times people think you need to just throw in a bigger set of injectors and go,
but that's not really the case.
You need a strong source, and that's where the Roush controller comes in.
Now, the really nice thing about the Roush Plug-n-Play controller is just that -- it's
plug and play.
There's no need to mess with any wiring, so for those owners who dread anything wiring
related, myself included, this is a nice little addition because it's simply just gonna tap
into the factory fuel pump wiring in the trunk of your S550.
You have to make use of a ground there, but really that's about it.
Very straightforward for the installation.
We've talked about raising the boost here with the Phase Two upgrade.
We've definitely talked about raising your fuel or increasing the fueling capabilities.
Now let's talk spark.
And with the Phase Two upgrade, Roush does toss in the NGK Iridium plugs.
They are a one heat range polar plug than what you're probably running right now at
the Phase One kit.
And these guys will just be instrumental in preventing any detonation that can sometimes
come along with running more boost, tire cylinder pressures, more heat, things like that.
Now, just a heads up here, guys.
My plugs are already gapped in my Roush kit but it's never a bad idea to check these things.
0.9 mm is what you should be looking at for the gap, according to Roush.
So, just be sure to double check them with your gap tool before installing them.
Finally and maybe most importantly, we have the calibration to kind of tie it all together.
Now, the majority of the time here with the Roush kits, even their Supercharger kits,
they don't include a hand-held tuning or flashing device.
Instead, they give you this, your little tuning voucher that you will need to take to your
dealer and have flashed using the J2534 interface tool, and the RDT or Roush Diagnostic Tool
software.
So, don't be disappointed when you crack open that box for the first time and see a piece
of paper instead of a hand-held tuning device.
Now, if you do decide to go with the Roush calibration or voucher and you do take it
to your dealer, more than likely they'll probably charge you for about an hour's worth of labor
here, roughly around 100 bucks.
Don't take that as a gospel.
Different dealers, I'm sure, will charge different rates.
That's just kind of a ball park estimate.
Now, you're not obligated to go with the Roush calibration.
Of course there are several different custom tuning options out there.
VMP is a biggie, of course, that we sell here at AM.
And if you do decide to go the custom tuning route, here's a couple of things to consider.
You will need a device such as the SCT X4 for instance.
And if you do go custom, more than likely you're gonna eliminate that three year 36,000
mile warranty from Roush.
So, a couple of things to consider if you do decide to go the custom tuning route.
Switching gears, let's briefly graze over the install, guys.
We're not going step by step here.
Instead, we're just gonna give you a general overview of what to expect.
And I did land this at a two out of three wrenches on the difficulty meter as a collective
here, not because each individual part's actually tough to install, in fact, it's quite the
opposite.
Just because there are a few parts to install, and you do have to take of that calibration
either from Roush and your dealer on the custom route.
So overall, two out of three wrenches on the difficulty meter is what I'm sticking to here,
maybe a few hours from start to finish excluding that calibration.
As for that pulley, well, we already covered that earlier, guys.
Very simple to swap in the Roush TVS2300.
No specialty tools like a pulley or a removal tool, or anything like that.
It's just simply six bolts, slack the belt, swap the pulley, and re-tighten the belt there
and you're good to go.
The spark plugs here on the other hand, well, that's pretty much wrenching 101, right guys?
A five eighths spark plug socket, a little anti seize for the new spark plugs going in,
and that one's pretty much self-explanatory.
Last but not least that fuel pump booster.
Again, Plug-n-Play making your install much easier.
It's gonna end up in the trunk somewhere.
You've got to find a little home for it.
3M tape, you can drill it into the actual spare tire well.
Whatever the case, the physical installation is straightforward.
Plug it in and you're good to go.
This one's pretty simple.
