There's a lot more to e.t.'s than rwhp. TweekedGT is right on about atmospheric conditions. Cal's uncorrected power yesterday was probably at least 12+hp higher than SAE. That helps but everyone gets that advantage on days like that including my car. My Cobra ran the best number last year at...

Guys are hitting high 11's with 03 Mach 1's with as little as 310 rwhp. They strip the cars to get the weight down to 2900lbs,run MT ET Streets, 4.30 gears, sub 1.6 short times by side stepping the clutch at 6500 rpm's. It beats the Hell out of the car and is very expesnive. It would be...

Here's a better view of the dyno graph before and after the SCT tune. Pete

I bought a Screaming Yellow one on Thurs. As I own a Dyno-jet dyno and am an SCT dealer we dumped the oil, baselined it on the dyno and already burned a chip. The car baselined at an SAE corrected 385hp/361lb-ft and after the SCT tune we got it to 392hp/385 lb-ft. The motor gained 16hp and 30...

Spend a $100 and put it on a chassis dyno. You're guessing if you don't. All the answers will be on your graph. We see it all the time. Pete

As the owner of a Chassis Dyno shop we see cars all the time with the right parts but way out of tune. What's your initial and total timing set at? We've picked up as much as 90hp on cars with retarded or way advanced timing. With the parts you have you should be running 10 mph faster. I...

Guys, check out the videos at the bottom, just got them on this morning, courtesy of Mac[h]Z. Anyone interested in stopping by next Sat. is welcome, bring your car as we will probably have time to throw it on the dyno. Pete www.performance-dyno.com

There was a difference between the '69-'70 and '71 and later. There were quite a few interior and exterior upgrades with the Mach1 package at first including at least a 351-2v with 9" rear end. After '71 the Mach 1 could come with a 302-2v engine and I don't think there was much of an interior...

They changed that in '71 or '72. After '70, the Mach 1 was nothing more than stickers and scoops. All Mach 1's in '69 and '70 came with the 9" rear end as Ford put them behind the 351 and higher engines and that's the minumum size for the Mach 1 those 2 years. The minumum engine went to 302...
