BAM!
The owner of the shop I use to work on my car wanted to build his car(A Yellow Terimator) to make 600 whp with the factory Eaton and no other power adder and he did. If I'm not mistaken it has the stock botttom end with ported heads/cams. fully exhaust, etc. I'm pretty sure its on pump gas to. Ya'll might rember the 735 whp Cobra running 18 psi. These are the same people who built and own that car.

nice numbers, Some guy near me has a silver 03, making 545 on pump gas, 570 with race on an Eaton, I was pretty impressed.

Those are impressive #'s on a ported Eaton. 
Dave his his #'s like this.

25*. I had not seen the article on steggys website, but I can promise you they will be the first people I will call on Monday morning, I want my new T-shirt.....dammit! My car before the heads and cams would make 530 all day long, cooled and ice in the intercooler reservoir would make 550. All on pump gas. Now it makes 580 hot, 600 with everything iced. The exhaust is a DynoMax Ultra Flow catback, Kooks 1 5/8 longtubes and catted Kooks X-midpipe. Pulley combo is 2.8 upper and 2lb lower. There's a few more little tricks that I think could pull a little more out of it, but for what? The Eaton is running out on top, and now it's time to see what the heads and cams are worth with a Whipple on it vs one with out the heads and cams. Stay tuned.....

remember he still had ported heads and blower cams, thos probably added a fair bit of that power, and factory = factory NOT a ported eaton just my .02

A ported Eaton is still a factory blower, its just been ported. 600 whp with a ported Eaton, on pump gas has only been done one other time that I know of. JDM did it back in 04. It is extraordinary good. Throw on a screw blower and you will probably be looking at 680+ whp with a stock bottomend on pump gas. |

nice but why NOT port the blower while doing all that stuff... just extra power...

It does have a Steggy ported blower. I just neglected to mention it and I copied my post on svtperformance.
Look here.

he did port the blower which was my entire point about the blower not being factory any more

IMO a ported eaton is no longer considered "Stock". its a modified version of the supplied OE part. still badass however.

a nice upgraded blower will put less strain on the engine and produce more power on the same psi.

I don't think it would put any less strain on the motor if he runs a screw blower at the same boost level, but idk. He runs a performance shop and he is developing a head/cam combo to sell and he was test it to see how efficent it would be on with a ported Eaton. With this combo he already made 735 whp in a Whippled Cobra with a 302 stroker kit at 18psi on 93 octane. He set a goal to make 600 hp with an Eaton on pump gas and he did it. He intends to step up to a Whipple in a few months. Read the quotes I posted in the third post and it clarifies may things. |

No...because an eaton spinning that hard is not long for this world...too much can go wrong in that setup when you look at the amount of heat being generated by that heaton at those rpms...hell, I'm borderline spinning it too hard now...
Now, the bore, porting, and headers...I do plan on those...but when I go for 600, it won't be with the heaton....too risky

The Eaton is not spinning any faster, working any harder, or creating any more heat than any other same stage Steggy ported Eaton run a #2/2.8 pulley combination. With that pulley combo what would that be, maybe 16, or 17 psi? I've seen were quite a few people are running a #4/2.76 combination. And I'm honestly not trying to harp ya'll, its just ya'll are missing my point, and I've been trying to get it through to everybody at svtperformance  and some are getting it and some aren't.(or they just aren't reading all the post) The ported blower on this car wouldn't nessessarily make anymore power than it would on any other Cobra with the same pulley combo and boltons. What took him to 600 whp was the ported heads and custom ground Comp cams he developed for the car. The car should run fine as long as he keeps it cool and enough fuel going to it. He will agree that it would be much better to run this combo with a screw blower as that is what he developed this head/cam kit for, but he wanted to see how it would work on his car with and Eaton before he starts sell them, but yes the Eaton is pretty much maxed out at this point but so would a 520 whp Cobra with a ported Eaton running the same boost be. He intends to add a Whipple in the next few months. I guess I am also just bragging on the guy because he's the one who works on my car and is a pretty cool dude, but I think its great that people are looking for ways to make power out of these cars other than just adding a more efficient blower or more boost. Like I said he already built a car with pretty much the same mods, plus a 302 stroker motor and a 2.3L Whipple that made 735 whp at only 18psi, and it a DD, and thats pretty impressive.

But if he is running 16-17 psi...with headers, ported heads, ported intake, etc...he is spinning it harder than someone like me that is running 16-17 psi with stock heads, manifolds, etc.
When you port stuff, you lose PSI...you don't lose power, just PSI...then you can crank it back up to the original PSI level and that's where you gain your power with headers and what not.
So, if he is running 17 psi...
Oh, and fyi ( just looked this up for clarification )...a 2.8 w 2# lower is just a tick under 16 psi....so with the port work, and the freeing up of air flow from the port, I will give him 15ish psi instead of losing 1-2 psi...

None the less, those are good numbers on an eaton...but you are working the hell out of that thing...and running some interesting timing to get there...too risky in my book.

/\Finally someone who understand that boost is just the result of a bottleneck in a airflow system.
