3.0 liter pushing 8psi of boost . Lots of hp! Not dynoed yet , but pulls like a v8.lots of fuel keeps things happy , larger injectors , boost fuel pressure regulator. And also a 7th injector to keep the charge cool.boost retard system for timing . Was running 10 rib belt on supercharger , but just installed cog system . No slippage!😉 Running a 3.58 rear and you can still light up the tires in 2nd. Very happy with results , but always improving set up. Keeping boost low so it can be a fun track car and most important reliable . Seat of the pants dyno must be at least 300hp running 100 octane. Lots of fun trying to keep it straight!
