Not much information there... What's the story?
Doesn't even sound like an S65 to me. "Kit"? Not likely. Custom one-off system? Likely. |

The stock rods can't take much more than the 400 lbs rwtq you might see from a well modded stage 2 centrigugal. The stock compression won't allow much more cylinder pressure on pump gas than you see with a stage 2 centrifugal. Twin turbos should make more boost and thus more cylinder pressure sooner, and the S65 won't tolerate it sooner. Even if you run E85 to push the detonation away, you are still limited by the stock rods.
If the kit can be made cheaper or simpler or easier to install than a centrifugal but make around the same power to keep a stock motor together on pump gas, there should be a market. I suspect the twin turbo will be a built motor only system. Even if you have E85 available and want to change just the rods, you have to take the motor apart to change the rods. At that level of labor, I'd change the pistons as well to ones more durable under boost. Then you have at least a built shortblock. Not Cheap, plus you have the price of the kit. I like twin turbo V8s. Audi has one, Mercedes, Porsche, BMW. But they may not be so easy to make in the aftermarket. |

Better than a raspy tin can sound
Still yes there is only so much you can push the stock internals. Look at what's his face who had gintani TT his, blew. TT come on non linear and much earlier, that's more stress on the rods, etc. Go to a different platform. 600hp is enough imo for this car |

Calling BS. There is barely any room to fit a single turbo, much less the setup and plumbing for 2. Also, there is no turbo spool in any part of that video.
Lets say you figure out some way to fit it all, there is no benefit to turbocharging the vehicle when the engine can really only handle 8-10PSI of boost at max. Even running conservative amounts of boost (12-16psi) would destroy an S65. You would have to lower the compression ratio so low to compensate for the added boost at higher RPMs, that im not sure the engine would idle, much less build enough power to get the turbos to spool. Also, part of me wants to be wrong so bad. Always wanted to see a 1000whp M3 to shut GTR owners up. |

Yea but I doubt the engine would even last a year on 8psi with the TQ turbos made....it's to much on stock rods long term
