I thought you typoed and meant to say "20" ...

The MN12 is t-bird/cougar from '89-97 - came with NA 3.8L V6, Supercharged 3.8L V6 (otherwise known as the Thunderbird SC), 5.0's were an option, and then in '94 the 4.6L was available. in '96 they dropped the SC.

Funny thing was the SC 3.8L was rated at 220 HP, while the Mustang 5.0L was 225. But the SC put out more torque. They were close to being (if not were) Mustang killers out of the box.

SC's topped out higher than the Mustang, and even now with the Cobra, a likewise engined MN12 could top out even higher than the Cobra, I'm sure.

My '01 F250 V10 6.8L gets 16-16.5 on the highway even with 1000lbs in the back doing 75MPH. Not too shabby for a 415 cube that puts out 425ft/lbs torque NET. I'm lucky my FE 390 gets close to that GROSS, and the V10 is factory... unlike my 390

 

WOW. what tranny/gears are you runinng in that F250? I always heard the V10 was terrible for gas mileage.


I wanted a T-Bird SC for a long time. I just liked the way it looked.

Never heard them called an MN12 before..

 

Auto and 3.73 - should be below in my sig' - with a cab-high cap on the back, I get over 16 at 75MPH. Without the cap, it's down to 13 sometimes. 4.30's I've heard may get 1MPG less, but that's it. Also, I've done only 65MPH and got only 15MPG - go figure, other people have reported the same thing.

Towing heavy, I've heard less than 10, and I can get it down to 5MPG stop-and-go (hey, THAT's why those tires have no tread left)...

But for the power, 80% of peak torque at 1000RPM, and 425ft/lbs NET ? People pulling trailers out of toll booths with the 6-speed in 2nd and foot half-way to the floor are spinnnig their DRW's ... deep skirt block, like the FE, and cross-bolted mains and a steel crank.

Still like my FE though... but I keep thinking what would happen if I put a V10 into my '74 F250 (with a blower)

 

I had a '99 F350 CC DRW V10 5 spd with 4.30 gears. It got 12 mpg on the highway and like 8 pulling my 40ft trailer. Did a good job. The '00 PSD was even better at 15 mpg with 6 spd and 4.10 gears.

 

I keep thinking what would happen if after I build my 390 and put it in my '70 F-100 and put a blower on it.

 

Welllll, sorry I said that

Greg-you are right, I plain forgot about the SS and I was referring to a range approximate with what fordman's buddy is running (shhh, I own some GM stuff too).


I must admit that the Turbo T was quite a ride also. I had the priveledge of tune'in and test drivin one, lucky for me there were some open country roads available


LMAO!!! --Mike

 

The 87-93 5.0 mustang's tip'd the scales at 600~800lbs less and ran circles around the turbo coupe .
The TC's are very nice cars, but are too heavy to play the the Fox mustang crowd in the 1/4 mile game.
I would not dispute your top end claim, I've had my 5.0LX wound out at over 156mph... at the time it had 3.73's, off road h-pipe and u/d pullies... all else was stock original equipment... I doubt it would pull that high with the 3.08's tho... magazines used to say 138mph for top end stock... I believe it, and I would not be supried to see the stock 3.73 equiped TC's to run past 138mph... not to mention how comfy and quietly it would do so...
Now, my stock 5.0 motor'd full weight LX runs 12.9's, impressive time for stock motor, but if I were to run your TC from a roll out on the highway I should imagine I'd get a real good look at the back of that TC, as my 1/4 times are more about traction and 1/8th mile than putting impressive power down.


To the original post'r...
I'd be suprised if the 50 shot made much of a change on the distance between you and the vert V6 pony. That's gonna be about 30hp at the wheels... possibly less... I'd also be suprised if the 100 shot put you ahead thru the traps, definatly closer, but not likely ahead.

As suggested, find an 1/8 mile track to bully those little cars.

 

clean lx 12.9 seems a second to fast for a stock 5.0 with underdrive pulleys and h pipie.

 

Seems quick to me as well. But, if your cars is running 12.9s, it will walk a Tbird SC from any speed, provided you're not running 4.56 gears or somthing so tall you run out of gear on the top end.

My car put 307 HP to the ground, so let's call it 350 crank. It runs low 13s with a good driver. They have seen high 12s with superb drivers, and all the stars in alignment. It's a bit of a heavy car, around 3600-3800lbs loaded. What does a 92ish Fox body weigh?

 

oh ya... sorry... it only went 13.26 in that configuration.
it now sports long tube headers, 4.10's and a 76mm mass air meter.
3240lb race weight, 1.70 short times, 84mph in the 1/8th. 234hp and 292tq. 2600d/a is the best weather it's run in... *should* go 12.6's @ 109 at sea level.

about 3200 for the lx. Stock times were 14.5 or so for the 1/4.

 

Do you mean Turbo Coupe or Super Coupe? Two different breeds of Ford 'birds

When you say "LX", do you mean Mustang or 'bird? Two entirely different species there...

To clarify, if the MN12 and the Mustang both have the same engine, same gear, theoretical top-end is going to be higher for the MN12.

 

ha.
I meant Super Coupe, but did abbriviate for Turbo Coupe. Yes, very different animals.

LX, Mustang...

top speed, stock, agree'd...

 

They will. with a carb, intake, and headders, mine runs high 15's.

That is real good for a stock cam and heads!
