Ultima intros Euro emissions compliant 800-hp package
Ultima Sports has created an 800 HP engine for its GTR and Can-Am rides that is emissions-friendly around the world. It will even pass the rather stringent Euro IV standards that have put paid to many a supercar's attempts to cross the pond.
Ultima's efforts start with Chevy's LS7 lump from the Z06, which rocks 505 HP standard. Ultima then adds their own exhaust, for a boost up to 565 HP. The camshafts are swapped out, raising the horse count to 650. Finally, a supercharger provides the 150 HP coup de grace, for a finally tally of 800. The entire package meets global emissions standards, as does every step in between.
Prices will be announced this weekend. If you'll remember, last year the Ultima GTR officially became the fastest supercar in the world, and that was with a 720 hp engine. Now you can go faster, and be cleaner about it. That sounds ultima indeed.
Thanks for the tip, Derek!

The exhaust alone makes a gain of gain 60hp?! The Z06 already has a really good exhaust, what more is there to change?!

The LS7 only has 1 camshaft.

1> Headers, headers, headers. Kooks Custom headers have shown massive gains on the LS7, try googling for it the details, but gains were 88hp/70lb-ft after headers and a tune.

#2 really? a V8 with only one camshaft?? how does that work?

Pushrods--1950s V8 technology.

FIRST OVER-HEAD CAM WAS MADE BY FIAT IN 1912,NOTHING LIKE MODERN TECHNOLOGY!!!

Theres nothing wrong with 50s technology.
Note that DOHC engines are 1912 technology. ;)

Also the exhaust on a mid-engine car is much shorter than the FR Corvette, so that alone will be adding horsepower. It's just 4-1 headers with a muffler on the end.

Yeah anyone who says ohv engines are 'outdated' doesn't realize that they are newer than ohc designs.
Its like the morons that say GM killed the electric car, when 25% of all cars bought in what, about 1910 were...electric. They were just terrible. About 25% were STEAM powered too. There is a reason they went away - they all sucked.
Fools with no sense of history OR engineering commenting on both. Fantastic.

Electric cars are still running today, we drive them every day. The latest Toyota RAV4-EV is completely gas-free, and is entirely different than primitive EVs just as current gas cars are far advanced from the 1903 Ford.
Wake up and take a ride in an EV, once you go electric you don't go back to dinosaur cars. Of course Chevron hates EVs, and fears them...
That's why CHEVRON, an OIL COMPANY, purchased control of the batteries needed by Toyota and sued Toyota to stop them from making oil-free cars.

Even if it was old technology, who cares? What other cars post the performance and efficiency numbers of the LS7 and still manage to keep the costs the same?? There is such a thing as over-engineering, Just ask anyone who has bought a brand new S class where half the electronics don't work LOL. If a piece of 1950's tech works just as well or BETTER then a piece of 2000 tech, then so be it. BY THE WAY, another piece of technology that was pioneered in the 1950's... Hardtop Convertibles. Thats right my friend has a recently restored 1958 Ford Fairlane with a FULLY AUTOMATED HARDTOP CONVERTIBLE, look it up. Just something to think about the next time you look your nose down on 1950's technology... they were just as clever back then as we are now.

Man that LS7 is old and worn out! Why would anyone want a "pushrod" engine that produces 500 hp, propels the Z06 to 60 in 3.5 seconds and gets 26 mpg highway. MAN, that old tech sure is inefficient. Sign me up for a sewing machine on wheels please!
