RE: Gear ratio
ORIGINAL: Jeremiah 29:11 What was cool was the older Ford GT40 could hit 93 MPH in 1st gear alone. No wonder they would win in the quarter mile when they were not racing in Le Mans. |
RE: Gear ratio
The old versions had several different ratios on the Mach I,II,III, IV versions. My favorite was the Mach II.
What was amazing was these cars weighed around 2500 lbs, would generate 475 HP and many time much more at 5K RPM. On one of the older version the ratios were: TRANSMISSION Type ZF 5 DS-25 Transaxle Ratios Final Drive 4.22 : 1 (Optional) 3.33 : 1 Gearbox First 2.42 : 1 Second 1.47 : 1 Third 1.09 : 1 Fourth 0.96 : 1 Fifth 0.85 : 1 Reverse 3.75 : 1 On the Recent version it was: Type 6-speed manual Gear Ratios 1 - 2.61 2 - 1.71 3 - 1.23 4 - 0.94 5 - 0.77 6 - 0.63 Reverse - 3.135 |
RE: Gear ratio
Wow! Which final drive did the one that went 93 mph have?

RE: Gear ratio
That was one impressive car especially for its time. I wish Ford could have put in the same level of effort into the GT.

RE: Gear ratio
Man, pretty impressive findings since I first posted this thread. Never would have TRULY expected 3:92 gears w/ the 6 spd as rumored. I know, that's w/ 20" wheels, but still, some serious gears behind a stick! Just wish it was a solid axle...personal preference. And man, can you imagine if they offered a Dana as an option??? Sweeet.

RE: Gear ratio
Yep, but as we know, even w/ 3:06 and automatic they slapped the Guzzler tax. It is inevitable, especially the way the CAFE standards are headed. Ugh
