The only downside to the termi that the mach1 has the advantage on is the SRA if going from a dig is a high priority. Although I hear it's pretty easy for a termi guy to straight trade a IRS for a SRA so that may be null.

Even if you got a mach for 5k cheaper and plan on using that additional money toward a SC setup your still at a disadvantage as the termi comes with a forged bottom end. Not only that, but a nice t56 trans too. The mach is going to need alot of money to even the playing field with a termi's potential.

Chalk up another one. No way is a mach better than a termi as far as stock/bolt ons go.

Terminators have been lower-mid 12s, bone stock. I believe 12.3x is the lowest on stock tires. Stock LS1 has been as low as 12.7, and Mach 1 has been as quick as 12.9x or 13.0. This is where those "hero" times come into play, because now we are talking about what the cars are capable of. Those times for all three cars were run on great days, at great tracks, and two of them even had the same great driver. The terminator beat the LS1 by .4s, with let's say a ~60 rwhp advantage. And it weighs about 200lbs more. So when you get as close to apples v. apples as we can, their times are pretty spot-on. Same goes with the Mach 1; a 30-40rwhp disadvantage, and a ~.3-. 4s time difference.

Who said anything about geared? And I made the comparison because we are talking about cars with equal power...did you miss that? I used an LS1 and a modded Mach for that comparison, but I could just as easily use a 6spd LT1 vs. a 5spd Mach, both stock (or close). Guess who wins that one 99/100 times? And for the record, Stopsign never said Mach 1s were faster than Cobras, he said that they used their power more efficiently, because of weight and gearing.

termi is way more efficient all the way around. on your post i was pointing out the fact that 4.6 na motors suck. the 5.0 is great but 4.6s struggle without fi

He asked what a Mach1 has going for it over a Cobra. Who said anything about a Mach being faster?

stoppy my opinion of efficent = fastest car bolt on for = bolt on. he was trying to figure out how a mach was more efficent than a termi. so am i how is the mach more efficient. i see what you posted and understand the pros of those options just dont see the mach as more effient and thats what he asked

10:1 compression, aluminum block, TR-3650 gearing over T56, solid axle, and the ******* SHAKER!!!!!!!!!!!!!!!!

That is just my opinion though...

lol shaker and mullet go hand in hand 78ta joe dirt. you see what im sayin. efficency is also wich setup makes most power before detonation on pump gas.

In this case, we were talking about how cars run with the same amount of power.

Efficency does not mean which motor makes more power. A 454cid motor that makes 405rwhp isn't more efficent than a 350cid motor that makes 404rwhp.

aren't both motors in the termi and mach1 4.6's? Efficiency can be interpreted multiple ways, but when dealing with both these engines the one that comes out of the factory that is built for FI will be a better more cost effective platform for any one that wants to extract more power. With the mach1 you have to forge the bottom end and probably drop compression. With the termi, bolt on a KB or go turbo and leave the block alone thats only if 500whp isn't enough on the stock SC.

The coyotes seem like they are running faster than the cars with equal power. I saw a couple videos where bolt on 03/04 cobras were losing to pretty stock coyotes. The Mach's seem to hold their own
this is where it started. not really about equal power. the cars are not equal in power or weight that are mentioned. Then a guy asked why a mach was more efficient.

First we have to figure out what we are talking about effient wise. Gas, power, potential, cost, what?

Actually, THIS is where it started;

With the exception of pre SN95. Havent really seen enough coyotes to say the same.
And this is directly related to weight/gearing/ability to launch. A Mach 1 needs less power than a Cobra to run the same times. Y'all are making this too complicated

All that proves is alot of idiots own 03-04 Cobras. Problem is alot of people that were not "racers" thought "Hey this car is called the Terminator! I'm going to buy it and beat everyone!" but another problem is this type person couldn't shift their way out of a mailbox.

That can be said about any car really. It's not like the best drivers only buy mach1's and all the retards buy termi's. I'm sure there are plenty of people out there that can't drive a mach1 any where near it's potential. Besides, I don't think ford marketed the cobra as a "terminator".\
