Hey C, I was reading the upgrades on your beast and they are awesome. I have been considering similar upgrades and was wondering if you could provide an approximate cost for the works. Did you perform the installs yourself or were they performed by a supporting vendor?
I've seen just over 2000 rpm with full throttle, with out spinning the tires.
I would think that's a good indication that it has got to be at least 1800, maybe 2000.
The few extra ponies at low rpms from the 6.1 would probably raise the stall a couple hundred rpm.
