" Great news for the N55 community! I am pleased with the results for the boost and timing run, I think they speak for themselves. I feel justified in my claims that we built a solid product that just needed a couple bugs worked out, which is all part of the testing process. I believe this turbo is capable of much more, and with a little more tuning, some higher boost, possibly timing, it will break the 500 WHP barrier, and hopefully past it. I am very pleased with the spool as well, by 3000 RPM the stock turbo only has a 25 hp / 40 tq advantage, by 3500 / 3600 the turbo catches up and flat runs away from the restrictive stock turbo. The Garrett CHRA with its Dual Ball bearings, will also provide very quick transient response while shifting for minimal boost lost. Not only is this the first real N55 upgrade, it is also the first true Ball Bearing stock frame upgrade for the N54 or N55!
I would also like to add, we have FULLY addressed the DV matter, have a stack of DV's sitting in stock, all with the stronger spring, we have also purchased the same GM solenoid Terry is using, as well as having pigtails to create plug and play harnesses for the DV. You simply unplug your stock DV when swapping the turbo, route the plug up near the valve cover, plug the harness into the open plug, the other end to the solenoid, and run your vacuum lines. No cutting of anything on the car. Car can be returned to stock with little effort if turbo ever needs to be removed.
All the finished upgrades we have in stock are spoken for, and 1 of the 6 we are machining now. So 5 spots are open. We will actively be seeking more cores.
Again thanks for the patience, and as I said, we feel justified as we knew what the turbo was capable of all along, good to finally see it shine...
