Nextdoor neighbour works on the v8 line at Essex Engine Plant . Said they assembled four Mustang 4.6 3 valve motors with superchargers as test engines today. they were destined for the motor lab and rumoured to be cranking out 440 horsepower. Could this be a new GT option,aspecial edition or even a new cobra engine?

That could very well be for a Shelby edition, i think they will go without forced induction for the special editions like the Mach1 or Boss...If i only knew what car it's for and when it would be release, you can bet you a$$ that i would wait for it to come out.

If Wildo is right, and we have no reason to doubt him, this is for the Shelby which will replace the SVT Cobra.

Nice numbers! The WS6 I got is only rated at 325hp. Though on dyno day with other F-body guys it only pulled 302 at the rear wheels. Sure there's some loss from the crank to the wheels but I should have pulled better numbers. It was running way too lean, 15 to 1 @ 5200 rpms, which is where she is supposed to be pulling max hp. In the shop next week to find out why and fix it. Other guys that just switched the intake box and exhaust were pulling around 345hp at the rear wheels though. That will be my first mod this summer. Torque is supposed to be 350 lbs ft, I pulled 329. If they drop that motor in the shelby's, their gonna be opening a big can of woop a$$ on the street! Now I remember why I wanted to wait for a shelby... There was a guy at one of the F-body meets that had a supercharger on his WS6, dyno'ed at 485 hp! There are ways to get more out of these... One of the other guys did a cam and heads and was up around 395 hp.

302 at the rear wheels means it's putting out more than 325 at the crank. A 20-30% loss is the norm from the crank to the wheels, I believe.

Maybe they were under rated??? Like I said, these guys that just did their intake and exhaust were in the mid 340's. I was expecting to reach the teens until we discovered the lean problem. Thank god the ECM retards things to avoid detonation...

Still, not bad numbers for bone stock.

Man, I am having a major Mustang Jones. All you guys ordering your cars, all the talk about Shelby, SVT, Roush, Saleen, etc. I am holding out for an SVT (or Shelby). It is driving me nuts. This news just makes it that much stronger. 440 from the factory. Should be easy to tweak it up to 500 with simple inexpensive mods. I can't wait. <takes another valium and walks away from the computer>

wouldnt the Romeo plant handle the SVT motors

they also may just be trying to blow up the gt's 3v motors

makes sense. To see how much abuse they can handle. I wonder what they got from it?

The LS-1 F-bodies are definitely underrated and aren't as detuned as you'd think. They just don't turn in as good of track times as LS-1 Corvettes because of weight, drag, suspension, gearing, etc.

How do the 05 F-bodies stack up??

I'm with you .... :hiding: until 2007

dont mean to be rude...but

NO SHELBY WILL EVER REPLACE THE SVT Cobra!

Actually, I doubt that. I would think they would have done that before deciding this was to be the mustang motor. They know it will get supercharged, surely they would have tested that long before the final decision on this motor.

I think they are test engines for an upcoming car.

crazyhorse

I agree that they shouldn't replace the Cobra with a Shelby badged car. I think there will be a Cobra and the Shelby will be the SE. If they do, however, replace the Cobra with a Shelby, that will not stop me from buying one. I'll buy whatever the hottest Mustang is (short of Cobra R. Love to have one, but, I want to be able to drive mine more than I would an "R").

It makes sense, Ford has said the present DOHC S/C engine out of production and never will return.

Do you know if the 3V has an aluminum block?

A 3V, SOHC, aluminum block with a twin screw S/C would make a lot of sense. It would make more HP than the old SVT Cobra engine, weight at least 100 lb less, would be physically smaller and cost less to manufacture.

okay, enoguh with the joke. you know they stopped making the f bodies in 2003

mr-mstng

The aluminum block won't be as strong, that's why the 03/04s aren't Al.

Also, why would it be physically smaller, and cost less to make?

Yeah, and where's **** Germany now?

Same point made. Old history, live in the now.
