Re-tune!

After a few months of delays and false starts, Joe and I finally managed to installed the larger injectors and get the car (re)tuned. We installed a stronger wastegate spring and had Steve the Tuner do his magic on the dyno.

Long story writ short: I'm now running 12.5psi of boost in the car. RWHP hit 271hp and torque was measured at 219lbf-ft. Assuming a 15% drivetrain loss, this equates to ~320hp and ~260lbf-ft of torque. If I assume 20% drivetrain losses, the numbers jump to 340hp and 275lbf-ft.

Said even more simply: the car is a beast. The only downside is I now need to run octane booster in the car, as we ran into a little detonation at 4500rpm. But that's a small price to pay for incredible performance.

More to come...
