Could you tell me please what was your final HP and TQ of your GT1 replica?
The GT1 replica is built around a completely standard engine/internals and fitted with hybrid turbos - last mapping with the Motec yielded 485bhp / 420lb/ft.
The ex-5th gear car engine was built with forged pistons, ported cylinder head, special BE bearings and hybrid turbos. With a custom EFI calibration it made 508bhp / 436lb/ft.
The asking price for the GT1 replica is excessive. I sold the car in 2009 for 30K€ - he is asking 65K GBP. It is a lovely car with some really nice features, but not worth 65K !
Thank you Mike. By "standard" internals, I hope, you don't mean OE cast pistons?
That is exactly what I mean. When I had the car, we had the engine producing 430bhp with 0.8 bar boost - the chargecooling was just to create dependable power, not a big outpuit. After I sold the car, they remapped the M800 and squeezed 485 but made no further enhancement to the engine itself. The engine has done very low miles - less than 4000 since the engine refresh.
