Hey everyone, I am new and have been frequenting the forum lately for a couple months now. So I decided to register when I found this link. It looks to be from this Igor you guys so often refer to.

Enjoy, I was leaning towards the Camaro but wow, this is it...especially if there is weight reduction with the upcoming Mustang.

 

Wow! Good news! I wonder what the displacment will be on the new motor!

 

Lol...it says 5.0L in the article but =P

 

Ohh, didnt relize that was the motor they were talking about. I thought the article was about another motor being built just for the mustang. Its kinda late. My bad!!

 

Nothing really new there, just Igor reporting what has been mentioned by (more than likely) multiple sources.

 

Welcome!


The article mentions that the 5.0 V8 headed for the GT will make "a respectable 400 – 425 horses, and similar torque...". Does this mean we can actually expect a 425HP Mustang GT?! I was thinking 325-350HP...

Btw, doesn't it boggle the mind a bit that Ford would bother naming an engine "BOSS" and then not have plans to put it in the Mustang?

 

I think 80 HP a liter/400 HP is possible with VVT and DI. A lot of the luxury brands, Lexus, Cadillac, Audi are making similar power. I guess the only question is if Ford would put this motor in a GT or save it for a SE.

 

When you think of it, however, Lexus, BMW, etc, etc. Is getting there numbers from 4.0L this one is a 5.0L so although it is refined I think it takes advantage of keeping the displacement up, and the "suffistication" costs down.

 

That would be sweet indeed. I like the higher tech alternative to the LS and Hemi motors. 80 ponies per liter is hardly stretching the specific output envelope at all these days and with 4 holes, VVT and DI, that should easily be doable all while maintaining decent emissions, economy and a broad power band. Back it up with a six speed and bring the ride/handling level up to contemporary standards with the long-dormant IRS and Ford could readily have a fully competitive GT against the Camaro and Challenger. Perhaps then too, the S-197 Mustang GT could finally credibly realize Ford's early proclamations of being a poor man's M3 rather than its current retreat into a narrow drag racer niche.

I imagine the Boss motor, while tagged for trailer hauling duty, would make a perfect Mach I motor and drag queen -- I'm presuming an OHC design and more emphasis on low-mid range power and torque than a back road screamer the 5.0 will likely be. But I imagine future CAFE and EPA standards will cause motors to trend towards smaller, higher efficiency designs rather than big-cube broad axes.

 

Yeah, doesn't Lexus have a 385hp 4.6L?

 

even Hyundai has a 4.6L NA good for 375hp

And more cutting edge naturally aspirated V8s are pushing even higher hp/l outputs:

Audi's 4.2 R motor putting out 420hp (1hp/l)
BMW's 4.0 M motor putting out 420hp (1.08hp/l)
Ferrari's 4.2 putting out nearly 500hp (119hp/l)

So yes, a 400/425hp 5.0 really is well within the realm of contemporary specific outputs. It would certainly be a highly-tuned sporting piece, but hardly on the bleeding edge.

 

4 valves per cylinder will certainly help with the power output.

 

Yes, but the torque on two of the 3 cars listed here are alot less than the claim of what Ford's 5.0 will be.

 

Very true, and you know Ford's factory tune will have some low end grunt.

 

How come there's an asterisk next to the 375?

And notice it says "Peak horsepower" and fails to give a TQ rating.

 

the asterisk is rating with premium fuel, TQ is 333, this is down however from earlier reports of 400 HP and 350 TQ.

 

Naw, that 400hp 5.0 would make a gem of a drag motor as well if properly backed by enough gears and cogged right (like say an M6 with a single overdrive rather than a double overdrive), pair that with a stick axle, a lighter 1 piece driveshaft and some final drive gears in the high 2s or low 3s and you'd have a nice effcient drivetrain as well (would certianly offset the penalty of a 6 gear trans).

 

When and If this happens, its going to make our cars look extremly slow, especially guys like me that are bone stock still,,

 

Call me a pessimist, but I have to see it to believe it. Its rumored that the 2010 Mustang will be released in spring of 2009. Do you really think the engine will be ready for production by then?

400hp Mustang GT? I would be the happiest guy on this board, if true. I doubt it. Maybe 350hp with the new 5.0
I expect a SE Mustang to have 400hp.

I still think Ford is going to be slow, and we will see a version of the 315hp Bullitt engine in the 2010 Mustang GT.
