MACH1 isn't quicker in all situations. It is in the 1/4 mi though. Lets try an oval track or longer track. Then the Mach isn't such an obvious winner. It also isn't better IMHO. It doesn't have the IRS. I don't believe the IRS is weak. Walsh motorsports has a 99 Cobra coupe running 9's with a stock IRS setup. I was suprised myself that the Mach1 runs such good times and has such great stock power. The cool thing is they've made a lot of Mach1's and they come with the engine that was in the 99/01 Cobras! Should make the mod market better for everyone. I seen a dyno sheet of a guy at Milan that had a new Mach1 and ran 13.4 (his first time at a track). Not bad considering I ran a best of 13.6 in my 99 Cobra in stock form! The mach1 is a sweet fast car but I'll stick w/ my car. No way would I trade in my 99 on one. NO WAY. Now if someone was going to give me a new 03 Mach1 or a used 99 Cobra I'd take the Mach cuz it is worth more $$$!
