NFS Lancer Ralliart
Not yet. I have a few things to work out for the time being. I have been busy as hell with other things, as of late.
The revised goal with this car is to make 400/400 with the RAD. I will be sending off a manifold to GrimmSpeed in the coming weeks. I also hope to settle on a set of aftermarket camshafts. I will also bite the bullet and upgrade the exhaust. I plan to use Ultimate Racing pieces all the way back. I even have a few things from Flowmaster sitting in the garage to help quiet down the drone. I expect that my idea will work like a charm.
If all of that doesn't get me there, I will join the dark-side and go E-85. I have the injectors to accomplish that (fingers crossed).

I couldn't say whether or not that BPV is going to be enough. I have no experience with either of those two.
Again, the Walboro isn't even going to be enough. You will more than likely need a new set of injectors, as well. These are basic fuel system upgrades.
The Hallman is great at keeping boost level very constant. It is also easy to adjust, which was the issue in this case. 19 psi was not what we were aiming for. With new injectors, I hope to be up around 24 or so PSI. That is the goal, anyway.

I'm running a walbro 255 with a Magnus fuel kit and I'm at 465whp/447wtq on 94 octane, so your good there

Many new developments. I have a new GSR, and I love it. No more transmission issues (for the time being).
I have a new set of powder-coated (black) AGP pipes, intercooler, and CAI coming tomorrow. I also have a new turbocharger and manifold ordered to be coated and ported with a new WGA. I still have my 3-port BCS and TiAL QR from the RA. I will be handing my new GSR over to Jestr (hopefully) next week to tune everything.
I also had the RobiSpec Clubsport coil-overs corner balanced. The brake are great. I just re-did both the brake lines and clutch lines with Braided-SS lines and fittings. I also replaced the CMC and clutch/flywheel. Exedy Stage 1 is a great clutch. It really is. It is so much fun to drive the car now.
I miss the Ralliart...sometimes. But the truth of the matter is that the Evolution, in terms of how it looks on the inside and out, "feels" the same. Does that make sense? It drives DRASTICALLY differently, but the little things are all the same.
The Ralliart BPV will leak. The Evolution X metal unit will hold, but it has a tendency to "fluctuate" boost levels in medium throttle and leak past 21 or so PSI. I have a different take on this phenomenon. According to several people in the field whom I have asked about this, the X BPV is actually designed to leak. With the stock turbocharger (or RAD in this case), the surge coming off of the thing will cause the BPV to "leak". In reality, this is just excess pressure blow-off. The problem is that the BPV doesn't close fast enough to prevent normal boost pressure from escaping. The Synapse Synchronic is able to actuate open and close SO QUICKLY, that this phenomenon is not even noticeable. It is able to create the illusion of linear boost increase across the power band. The stock Evolution X BPV is able to mimic this, but it still closes too slowly. Aftermarket BPV's are even worse, when it comes to this. If you plan to switch to this turbocharger, be warned. The TiAL QR that I had was unable to properly compensate for the turbo surge. It sounded like a rattle snake at half-throttle. It means that I should have gone with a much larger turbocharger. This small snail simply will not ever need one of those large diaphragm BPV's. I learned this the hard way.
If any of that analysis is wrong, I do apologize. It was purely based on observation and research. That is my theory on why the Synchronic is so good. It is, too. You would be hard pressed to find another stock replacement diverter valve. It works the same way that the stock unit does (not really, as it uses a completely different mechanism, but you get the point).
