I must be on viperalley!
(my personal experience) my 2nd gen whipple made 825 with no spray on a dynojet after we built the motor, first pass, no tunning,(on the same tune as before the the motor work), we didnt do anymore tunning as I was about to spray the car and we didnt have time. so we only tuned for spray after,
I would imagine with a little more tunning we would have reached 850is
that was on 20 lbs of boost
we didnt change the compression on my motor and we picked up near 90 hp with the cams, and ported heads alone. that makes a difference and increasing the compression makes yet more of a difference, there is no doubt in my mind that eds car will make everybit of 850, i would go as far as saying if he really wanted to on race gas and 4 liter whipple and enough fuel it will make well over a 1000
but I like mullets idea of side by side,
maybe at one of the future rallys we can have a side by side half a mile race or something like that. I wouldnt miss that rally
