Damn, stupid memory I coulda swore it wasn't such a porker. Oh well, must be that 5.4! Although honestly I can feature where they put on the pounds being that the car uses alot of aluminum????? Then again if tey scrapped those 4v heads and put some 3v heads on there they could shed some 70 pounds (or atleast I hear that 4v castings are 35 pounds heavier than 2 and 3v heads)

That's what I get for assuming.....I stand....errr sit corrected. I did a quick search on Ricardo Trannies, and could find virtually no info on them. Oh well - thanks for setting me straight.

Re: Stock Ford GT dyno

Screw the top end who's gonna win the quarter mile?

MT reports 11.5 @127.1 for the ZO6 and 12.2 @118 for the viper. But I dont believe those numbers took place on the same day, let alone the same track. When are we gonna get a three way shoot-out?

You seem to know more about it then I do. It just seems to me HP and Aero are primarly what are considered important in top speed runs.
Basically. Top speed is reached when the thrust force equals the drag force. 747s weigh a hell of a lot but they are still pretty fast.

Hah, was reading about the Veryon, it takes 500hp to hit 189 mph and another 500 to accelerate from 189 to 253 mph.

I don't know much about them. I believe they are an Italian company, although I could very well be mistaken.

Vipers have been running in the 11s stock since the days of the 450 horse GTS models. I believe the z06 will be faster, do to its weight advantage, but the Viper can do much better than a 12.2. We were discussing top end because someone brought it up earlier, and it is advantageous to have all the top end you can get on a big horsepower track.

Well, if they are English, looks like I stand corrected. I thought I remembered Clarkson remarking on the Ford GT having an Italian transaxle though. I must have misheard it for something else.

and its rated at 750 Nm or 553 ft/lbs. of torque, pretty hefty trans I guess ,550 ft/lbs. of torque in a 3500 pound car, I wonder if it would blow tranny chunks all over the track with a good set of slicks?

Heh, I guess there is only one way to find out, huh? Maybe some hapless owner will answer that question for us at some point in the future.

T56 or this Ricardo transaxle? The ricardo transaxle should be rated for more than 553 lb-ft tq. Atleast i would think so.

We shall know soon enough i guess. Hennessey will soon be offering a 800hp Twin turbo upgrade for the Ford GT.

The Supercharged 5.4 is what is killing it. On the z06, the Ls7 is fairly compact and lightweight helping the z06 maintain its light-weight nature. On the Ford GT, the blown 5.4 weighs around 690lbs, even with the aluminum block/heads. That's a lot of heft.

This is why i hope they ditch the blown 5.4 if they ever get serious about a GT replacement (which they kinda are). The 605hp 6.4L v10 on the Shelby Cobra concept is a much lighter alternative (200+lbs lighter than blown 5.4).

I don't think they would have used the supercharged 5.4 on the GT had they had time. As you recall, the GT was a rush job. On the GT replacement, they should have time to get an all-new and lighter engine in there.
