Hi all, you know if you guys would stop answering so well... I wouldn't have to post my questions...lol

Okay, so here's what I'm wondering. With all this talk about the '08' Challenger, Charger SRT-8, 300's, GTO's, 350Z's etc... coming out with these higher HP numbers 'stock' and the majority of them being larger engines, I was wondering if anyone knows what the potential of these engines are?

Example: I was told with my car that when I s/c, 400rwhp is about as high as I want to make safely before I have to start changing the internals. From what I've read off this site,the Mach 1 is approximately 450-500. Then there is the Cobra with forged internals to which people on this site have told me that close to 1000hp is possible out of the box.

So what I'm wondering is: since these newer engines are already a larger displacement, do they already come modified from the manufacturer and can they hold allot more power? And what would my 400rwhp do against these beasts seeing as they are heavier?

It's keeping your friends close but your enemies closer...lol Sorry about the interest outside of the 'Ford' but I'm seeing so many more of these cars daily excluding the Challenger so I just want to know what were up against!!

As always, thanks for your time!!

wondering the same thing but im pretty sure they come stock with forged internals to handle a lot of HP the charger does at least the SRT8 and i deffinetly know the challenger will have forged internals to handle a shit load of HP

First off. The Mach 1's and pre '03 Cobra's have the same internals as any v-8 GT. So the max safe hp rating will be the same. Potential of the engine may vary, but safe operation on stock internals is the same.

B. It's not necessarily true that any of the cars mentioned come with forged internals, but anything other than the hyperpathetic pistons and cheap rods will be better, allowing said engine to handle more power on stock internals. It's not that they are built ready to handle 800+ hp, but rather built with parts that are just a step above those that Ford uses. I'm not knocking Ford, (hell I'm one of those die hard "push a Ford before driving a Chevy" guys) but it's just the truth of the matter....

doesnt the mach 1 have a forged Crank?

the manual has a forged crank, which makes no sense at all considering that the weak link in the motors is not the crank. the cast crank can handle around 600- 650 hp. the pistons on the other hand go bye bye well before that...

Sorry... brain fart on that one detail...

+1 doesn't make sense, but it is what it is...

With 400 rwhp, that means about 470 crank hp, you should be able to take on all of these cars without much hassle. You are much lighter then all of them, with the exception of the 350z, and none of them generate 470 hp (and the 350z is only 300 hp, maybe 330 hp if nissan uses their new 3.7L V6).

+1 Thanks Busher that's what I was wondering although I just discovered on another forum the hidden potential of the Mach 1. Very nice out of the box.

Thanks Again.

No prob

Yeah the Machs are VERY nice, and underrated. I was going to get one, but I've decided to opt for a termi instead.

The 350z makes 300hp...And the cobra shortblock can handle 1000hp, but not safely...I think the stock shortblock would be a ticking time bomb at that level. Kinda like 500-600rwhp on the stock 302 2-bolt blocks...At 1000hp on any engine, i'd recommend good machining and balancing with very good internals...

as for the stock 96-04 4.6 mustangs excluding the 03-04 cobra, they all have a limit of about 450rwhp. Thats over 500 flywheel hp. With that much, beating those cars mentioned wont be an issue... With 450rwhp you should hang with some higher end cars many times the price of your own car. Notice hang though, i didnt say beat. Many cars at that level have gearing and aerodynamic advantages.
