Is 1000 HP possible ?

[ESPN8]

Hi . I have a 1997 Cobra that i bought from new . I had a supercharger along with numerous upgrades installed on it in 1999 . The Beast makes 445 rwhp . It was tunned by Sean Hyland himself all those years ago . Even now , the car only has 69000 KM,s ( 40 something 000 miles ) on it.
Well , needlesss to say , that power was HUGE back then ,
now , with 500 hp the Norm , i need something a little more power to keep ahead of the pack.
So ,back to the question . Is 1000 hp possible from a little 4.6 DOHC ? If so which way would you go about achieving it .Power adders , cams , head work and so on .
The car also needs to be drivable with good street maners .
We see Supras and other Japanesse cars making Big Power .
Let me know your thoughts .Thanks.

No, you need a heavy duty after market block.

1,000 hp is easily achievable from a 4.6L DOHC engine. You just need to select appropriately engineered components and make sure the engine is prepared properly. The cover of Sean Hyland's book, "How to Build Max-Performance 4.6-Liter Ford Engines" has a picture of an twin turbo engine that made 1,300 hp. In the back of the book, he lists what is needed to produce a 1,500 hp 96-98 Cobra engine (with B-heads, even). Of course he specifies his own components, but the point is that it can be done. You had just better have deep pockets. That's true regardless of the manufacturer though. A 1,000 hp Supra engine is not cheap.

nah you need money ,lots.

That is not true at all. The 93-98 Teksid blocks can easily handle 1,000 hp. It IS heavy duty. The later WAP aluminum blocks manufactured by Ford won't take that kind of power though.

Nope, your block needs to be built for that type of power and probably going turbo charged will help you with your goal of 1k hp. for the built block your looking at maybe 5k+ labor of pulling the engine and for power adder probably about 6k + labor too. Can be less if you budget it out and stuff though.


But getting an engine to make that much power is easy, building the components around it to take that much power is horrible. With 1k HP, you would for example, snap your rear pretty fast. You have an IRS which makes building it expensive. I plan to do a solid axle swap when I get my mustang because for you 2 axles would cost 1,000 or more, plus a new posi unit for 31 spline, since your stock is 28 spline. On a solid, you can do that for 500-600 bucks if you shop around. On an IRS you would be looking at 3-4x that much.

somebody chime in on how much fuel upgrades are for a 1000 hp im thinking 1500 -2000 bucks

Yep, you are looking at around 1600 for the kit

or a few hundred less if you know what your doing and part your kit together yourself.

+1

BTW, It's not really that hard to piece a kit together yourself.

exactly and your beast will hardly ever run right and always be broke down and lets not even talk bout traction.

 

[Venom351R]

I wouldnt want to try it on a stock 4.6 block, IMO

 

[Mach1USMC]

I'm no expert but I stayed at a Holiday Inn Express last nite!!!

JK- I'm pretty sure the Teksid block can handle the HP. But I think you would need a forged stroker- say 9.5 compression, FR500 Heads, blower cams, and a couple of 100mm turbos, 30-35 lbs of boost, race gas- that would get you in the ball park.

I'd just get the new 5.8 modular stroker longblock from MMR built for FI, big turbos and SAFELY get 1000 hp. Prolly about the same amount of $ at the end of the day.

the IRS wasn't available until 99 on the Cobra......but you are correct.- the stock rear end wouldn't last past the first WOT. He either needs to build his 8.8 Solid rear or get a built 9 inch with some 35 splines and a spool. Might want to upgrade the drive shaft too while you're at it. No way will the stocker hold 1000 hp. Fuel system upgrade as well.....

Basically strip the car and start from scratch.

Oops my bad, thanks!

I have Superior 31 spline axles, powertrax locker and 4.10 gears at the moment . Not sure if thats strong enough though .

Yup , my block is the Teksid one. So basically all the other compents would do the job ? Does the block need to be bored and stroked or is Stock bore good enough . I would like to keep the original block if possible .

 

[busakiller]

gonna need a power adder for 1k. but, easily attainable.

just remember 4.6 and 5.4 iron block cylinder walls distort once you go over 6000rpm with anything over 700hp. youre gonna need an aluminum block or keep the revs low.

i wouldnt trust this thing for very long at 1000hp with boost. i highlighted why. just my opinion.

All the Cobras have Alluminum blocks . If you check some of the Terminator Cobras , some of them equiped with little more than a Procharger F1 or Turbo,s come very close to the Magical 1000 hp.
