Another beast to join the 8 second club in the backyard 4G stable! 💥💥💥🦍🛫🚀

First outing with the new auto setup & 76mm Precision Turbo & Engine gen 2 turbo

2L 6bolt 4G63 powerplant
Vader alloy rods

Ran out of injector, only 4 fitted so couldn't turn the boost up any further from 60psi

Still on pump E85 a lot of potential in this beast with the power to weight ratio.
