Helping a friend dial in a 2017 auto car.
Only mods are gen 3 Whipple, 132mm tb, long tubes and supporting fuel. Currently running 3.25" pulley but plan to run the smallest possible upper without belt slip on stock 6 rib lower.
Current shift point is 7000 for fear of shattering factory opg's. Would like to rev it as high as safely possible after installing gears. My question is how high could we turn it once the gears are installed; and what upper pulley can we run without slipping at 7500+rpm on the 6 rib?
Haven't had it on the dyno yet plan to experiment with different air fuel and timing once it's all assembled. We're currently at 0.82 lambda and 20-23 degrees of timing on e40 fuel and plan to shift both those on the dyno to see what the car actually likes.
Any input from those with a similar combo would be appreciated. We just want to make sure we're headed in the right direction with mods before pulling the trigger on gears and pulleys.
