[QUOTE="Mulholland Man, post: 16471139, member: 191905"] Yes, it was modded. All bolt ons w/tune. 2.4" pulley and Metco Idler pulley. VMP Dual 68 TB, VMP Big Cold Air 123, SC Elbow hi flow, VMP Oil Sep both sides, MGW Short Shifter, Roush Axle Back Exhaust, Boost a Pump, Griggs Racing SS Suspension with Coil Overs, Watts Link, Torque Arm, Control Arms, Tuned and running 17 Max PSI Boost on 91 Octane. Dynoed at 650 RWHP on MUSTANG DYNO which converts roughly to 710 or so RWHP on Conventional Dyno. I bought the car with 5,000 Miles and didn't do a compression check at purchase. Did one several months later when I started adding mods and noticed that I had some lower compression in the 3 driver side cylinders but was still within spec of 10% from other cylinders. Added boost and more mods. Over time I think those weaker cylinders lost compression and became more worn and damaged with increased boost. I should have rebuilt engine as soon as I knew I had issues with the driver bank but did not. Pushed it and then Boom. [/QUOTE]
