Assuming it might be possible to keep your foot out of the floor for a little while, what kind of MPG's are you getting on a Sunday cruise?
Please include:
Engine Displacement, HP
Trans Type
Carb or injection?

Nuke,

I've got a Windsor stroker, 422". Tremec 5 speed trans, Holley 770 Street Avenger carb, 3.73 rear axle ratio, around 400hp. I've gotten as high as 17.5 mpg on a freeway cruise, more like 10-12 mpg on a spirited drive thru the hills of N.Ga.

331 with Kenne Bell supercharger at 5 psi, T5 and 3.08 rear gears. Cruising at 65 mph and no 'fun' I have seen 22/23 mpg. My normal gas mileage with some spirited driving is 14/15 mpg and if I am really having fun it drops well below 10 mpg.

Warmed over 302 with cArb somewhere around 24mpg, 5 speed standard with the stock gt gears, something like 273:1 or whatever the gt rear gears were in 93......steven

347 with about 450 HP carbed, T5 and 3.55 rear gear. Gets about 17 on the highway and 9-12 when sticking my foot in it.

I've only just discovered the Daytona while looking for a kit car to build in the future. I'm running LPG in my family car and I'm a convert. I reckon there should be no significant issue for the engine. It is a matter of space for the fuel tanks. Has anyone done or looked into this?

Yours Aye

I believe it can be done.........Steven

[MikeJones]

302 30 over, aimed at 325-350hp, T5, 3.73 rear, about 24mpg highway (2200rpm at 65mph (if I can convert correctly), and about 12-15mpg in city since it is hard to get out of 2nd or third

Regards, Mike

427 cubes, 600+hp, on Sunday cruise I average 18-19mpg. Cheaper to operate than my diesel pick up.

LPG tanks in a Daytona? Makes me think of the Road Warrior.

[turbonut48]

418 cubes, 530 hp. 5 spd, 3.50 rear gears. Still breaking it in, so havent been thrashing it.
Im only getting about 14 mpg. At least the fun quotient is way up.

[TXCoupe]

Well, 347, 750 carb, big heads, big cam, big HP, TKO, 3.73, 70mph @ 2500 N 5th = 12mpg. In town not nearly as good.
Fun factor = OMG

[Blue Horse]

Do not take is the wrong way but who cares anyway. SPM Smiles per mile = 100/gal.

Stock 302 and can not keep my foot out of if for a tank.

[Jeff Kleiner]

5.0 EFI, Trick Flow heads & intake, Stage 1 cam, 24# injectors, T5 w/ .68 5th gear and 3.55 rear end.

Steady 70-75 MPH highway only = 22+ mpg (Just checked it going to LCS and had a high of 25.5!)

Around town with an occasional squirt = ~15 mpg

Track days = ~5-6 mpg but who cares!

I have an 88' hatchback mustang with a stock 86' engine an 2.73 gears. It gets 25 mpg on the highway... A stock 5.0 set up should get better milage in a Coupe... It's lighter and has better aero.

[allbite]

Mine is a pretty close to stock '92 5.0 and driving around I average about 20. I have no doubt I could get well over 25 without trying too hard on the hwy.

[Stengun]

Howdy,

I have a Spyder Gt w/ a 414W EFI 500hp, Tremec 5-speed & 3.55 gears. Mileage? Who cares. It's not on the road yet but my daily driver F-150 gets about 15mpg so as long as it's not much lower, I'll be happy.

This is a really interesting thread. Several people have asked why bother about MPG in such a fun car and I can see their point, but in the UK (where I'll be driving most of the time), we passed the $10/gallon point a long time ago. For that reason, I'm researching V8 economy and looking at gearing/weight options. I'm also considering (please don't hate me) engines other than a V8, in particular, V6 or flat 4 options from a European or Japanese manufacturer. This is purely an economical decision based on fuel consumption and part availability. I already run a MG V6 (loads of parts around) and a Jeep diesel (really difficult to get parts, new or second-hand). American V8 remains my preferred option, though.

On the plus side, I have approached the wife with my short-list of kit-cars and the Type 65 Coupe got the most favourable response.

Yours Aye

I'd be willing to wager that if you were to take the entire drivetrain (engine, trans, rear axle) from a 2000-2004 4.6 Mustang and drop it into a Coupe without mods it would run close to 30 MPG on the highway, all the while being smooth, civilized and reliable.
