From my listening of the sound track and from my experience of trying to run my own video on this car, the engine noise is just destroyed by wind noise and too much gain. The engine is VERY loud on this car and it does hurt unless you wear earplugs.
Reason for selling was that I only put 6 hours on the car over 2 years. Same reason the Lotus is now going as that has only done about 5 hours over 7 years! Good sized dollops of cash that can be better used elsewhere, partly into Sea Ray 220 Select, 2 years old and only 56 hours on the clock and comes with 300 bhp Mag 350 MPI Bravo 3 drive.
Back in '94 (makes me feel old saying it that way) when we took 9 GTDs to the Ring, never having been before and with Paul co driving to remind of the direction of the next corner (yup, we made some pace notes) I did 8 laps in one day. Best was sub 10 minutes but I think the car can do much better than that now it is developed a lot more plus (I think) the driver has improved a little since then too! I have been offered chances to race at the Ring a couple of times now but I won't accept as it takes far too long to learn the track and when racing I would be an accident waiting to happen. The video of the 94 trip is, I think, on the GTD club web site.
