Since this is my first project, I had to use some code as a basis for this engine. Credit to Mr. C14 for the code.

Made a couple of changes, mainly towards the cross-sectional area, diff ratio for accurate rpm(now it's 4k rpm at 60mph/100kmh in 6th), exhaust collector, clutch engagement, redline(7600 instead of 7250), idle is lowered to 1150-1200ish now, reduced brake force, changed the cd, and I believe a few more. Top speed is now at 105MPH. HP and torque is a bit more with 49HP and 39 LB-FT. Now it should be more accurate to the real interceptor 650 engine.
