It seems like Boost Logic has the highest horsepower Nissan GT-R right now, making an incredible 823.39 horsepower and 670.89 lb feet of torque at 27 psi. The Nissan GT-R features the Boost Logic Turbo Kit, intercooler, exhaust system and fuel system.

According to Boost Logic:

After 2.5 months our first stage of high horsepower development has yielded results. This car features our turbo kit, intercooler, exhaust system, and our fuel system. The turbos on this setup are Journal Bearing so there is definitely spool to be had on simply upgrading that. This car will have a stroker engine in our next stage of modifications so spool will be closer to the stock insta-boost. The sound on the video does not come close to capturing this car’s amazing tone.

Here is the dyno graph… look at that power curve!
