I got my baby back, baby back baby back, I got my Baby back baby back!!
Sorry I came across as such a whiny bitch two months ago, promise it won't happen again.
Turned out my boost problem was just a loose vacuum hose.
The only Rotary guy in town quoted a rebuild at only $100 less than Pettit Racing (widely regarded as one of the best if not the premiere authority on Fds in the US.) They won the Rolex series GT class championship in 1998 with a modified 1993 rx7, and they've completed the 24 of Datona 4 times with their rx7. They ran in the ALMS in 1998 and have numerous scca victories under there belt. On top of all that they are really good people.
I spent the night at a friends in Orlando so I could arrive in West Palm beach at a decent hour (a solid 11 hrs from my home) When I first arrived the owner, Cam was working out a deal on some industrial rotary generators. While I was waiting Kandy, who is the most beautiful woman I've seen under the hood of a car, gave me an hour long tour of the shop. She performs all the machine work including ports on all their engines. She did talk me out of ceramic apex seals. They are indeed more durable than the original steel variety and for a while nearly all rotary tuners have been using them. Unfortunately, when they do go they shatter and give the same effect as diamonds in the engine, annihilating the rotor and housing. Cam spent at least an hour with me discussing options for my car. I was expecting to get the most professional service possible, but I had no idea how personable they would be. They even shuttled me too and from the Airport in an FD! When I picked her up, between testing and tuning, I spent about 6hrs around the shop. I assumed I would be one of their most distant customers, but there was a man there from New York and they had 2 engines shipped in from Europe as well as a supercharger order from Europe. If any European RX8 owners are reading this Cam was in the process of securing a partner in England to supply and install their RX8 superchargers.
Apart from the standard rebuild and street port I had their Blueprint Hi Flo Turbo upgrade* performed, Fluidyne race radiator, performance clutch, and 8.5 lb flywheel. They also did numerous little things to make my car feel new and prevent future problems.
She runs strong and sounds great. I had no problem keeping up with a C6 vet last weekend. :):D:D
*[QUOTE] Our blueprinted Hi-Flo or BPHF Turbo unit is far superior to the stock unmodified unit. The turbo housing is hand ported and contour radiused creating a bevel on all the unfinished edges left from mass production, this reduces the hot spots* and minimizes the chance for heat cracking, aside from improving longevity this procedure also improves flow path and efficiency of the unit. Next all mating flanges are machined flat and prepped for a ceramic thermal barrier coating to be applied, (this reduces heat radiation resulting in lower under hood temperatures) then the housings are reassembled in a fixture to assure proper alignment. For the compressor housings we also port and polish the tapered discharge outlet (snail) improving efficiency and spool up**. All this adds up to a much improved turbo unit that has proven it self by providing reliable performance for so many of our customers. The same basic turbo was used in our road racing RX7 to win the 1998 GT 2 Championship.
Our process actually provides a part that is superior to new. All new turbo castings are with out heat cycles or “green a casting”, Green parts are less stable and less resistant to warping and cracking due to internal stresses. Heat cycling relieves the stress and provides a more stable part, then with our modifications and coatings they become far superior.
For complete assemblies like the sequential and non-sequential turbo units, the housings are reassembled in an alignment fixture and torqued to factory specs.
The Ceramic Coatings reduce heat radiation resulting in lower under hood temperatures This is the exact same technology that Pettit Racing used to win GT Championships and finish grueling endurance races like the Rolex 24 at Daytona.
All the Twin Turbo RX7 turbo housings we receive have cracks, we have seen attempts to weld up the cracks but all have failed, and the weld material eventually comes loose destroying the exhaust turbine wheel on its way through the turbo.
We have found that once our modifications are done the old existing cracks*** are no longer a problem and we have never seen a crack related failure of our turbo housings. This is because our procedures minimize the hot spot areas, reducing the heat loads that cause the cracks. This alone makes a huge improvement in longevity, but then we apply the Ceramic Coating further reducing heat absorption by the whole manifold.
We have found that these procedures provide for much more efficient and robust turbo unit that will consistently deliver the most efficient and reliable performance for street or all out racing of any parts currently available.
One of the most important things we have found is getting a proper install of the turbo unit. Using anit-seeze on all the threads and proper torque on all the fasteners is a must, then after several good heat cycles we retorque the fasteners. It is also a good practice to retorque the fasteners twice yearly.
Warranty, 12 months form purchase date, If the part fails for any reason we will replace it free, you must obtain an RA# and return the failed part to us. We only provide the replacement part; we do not pay for shipping, installation labor or anything else.
We offer the same modification and blueprinting service for your turbo and/or manifold. Each turbo unit or manifold we receive for service is disassembled, inspected and quoted, prior to any costs being incurred.
* It is a fact that the OEM unmodified turbine housings as well as the new Jspec 99 style units have a design which creates an exhaust flow path that causes hot spots in several areas of the turbine housing, this leads to small cracks in the housing which will grow until finally creating exhaust leaks that make housing replacement necessary.
