This Grand National Makes 2000 HP!!
The Wisconsin-based Ringbrothers revealed their latest resto-mod beauty known as INVADR. Based off a 1987 Buick Grand National, the build stays close to its roots by keeping a 3.8-liter V-6, but the INVADR’s powertrain features custom hand-ported aluminum heads, a Bryant Racing billet crank, and twin Precision GEN 2 62mm turbochargers. At 50 psi of boost it’s good for 2000 hp, but for streetability, it’s been dropped back to 32 psi. What car do you want the Ringbrothers to get their hands on next?
