We are dynoing this coming week Dec 1st or 2nd for actual. By other dyno testing on the 850-860-902 we should be seeing about 57 WHP on 12.1.1 non turbo engine, with the correction factor of the CVT that would be in the ball park of 97 Crank horsepower on pump fuel.
 
97 hp out of a pump gas 950, push rod two valve motor? naaaaaaahh. That is 102.1 hp per liter. A Vette motor make 69 hp per liter and my engine makes 89 hp per liter. Dyno chart at the crank or it didn't happen. Or if it did, come race with us at V2R and kick all of our butts....:) Can't wait to race!
