More details on the 2003 Kenne Bell COBRA can be found on the following thread:

http://www.corral.net/forums/showthr...hreadid=179399

If I am not mistaken, a well tuned 422 ci LS1 with all the bolts ons (LS6 heads/intake, headers, etc.) will make around 550 rwHP and 550 rwTQ at the rear wheels.

With respect to cost, it looks like the 2003 Kenne Bell COBRA and a 422 ci LS1 will offer similar bang for the buck.

Most well tuned 422's make closer to 500 rwhp, 550 rwhp is more like a solid-roller set up.

600 HP w/o headers or ORP is awesome if the story is right.

That's a lot of power but 16-20 lbs of boost is a lot of boost, I'm more impressed (if) the block can take it for a year or so MORE so than the power I have a buddy who could make that power on 12 lbs of boost and on race gas in a 357ci LT1 with a supercharger. 20 lbs of boost is what mid 9 second cars run.

I hate to say i told you so, but wait until someone stuffs a large turbo atop of one these basically built from the factory motors. More power on the way. Although you are only a relatively small shot and about 800 bucks away from 800rwhp with the 422..... <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Pretty cool! The new Cobras have alot of potential, too bad there really isn't any support on modifying the engines internally. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

I've seen Supras pull over 750 rwhp with a stock shortblock. 3.0L and 6-cylinders, so this 4.6L V8 should be able to do that and more with a turbo setup.

The block's longevity shouldn't be an issue, as it is made of iron. Everything else in the motor is forged from the factory, save for the aluminum heads.

Great, I spend a grand and get 330rwhp, they spent a grand and they get 500rwhp.

Impressive for the Cobra, I do have a good bit of respect for these cars compared to the earlier year 4.6's...

Matt Sterbator

The Supra's I-6 configuration helps it hold up to the power.

What amazes me is these guys are nutting over 550rwhp @ 20lbs of boost thru a 32V V8 motor.....whooooopty friggin dooo.....the 93 Supra's with a single turbo upgrade can be made to hold 900rwhp on a BONE STOCK BOTTOM END...detroit is light years behind period. The LS1 Heads are a Warp jump compared to what else is coming out...now if GM put the LS1/LS6's together with an Iron block, steel crank, forged rods/pistons and pushrods that weren't made from toothpicks nothing Ford or any of the Japanese cars could touch it.....

I would pay anything to see what Frod and the rest would say if GM would put a motor like that together and supply a blower from the factory...geez that would be crazy sick power.

Stefan D.

Hey Josey, well said. Its only taken ford about 5 years to figure how to make a 32 valve motor work, well sort off, its a pig naturally aspirated so lets put a blower on it and hey were a regular bunch of rocket scientists. I will take a LS-1 car, a bunch of bolt ons and some spray and run that **** over. And you know what if the bottle goes empty I will still be some where in the high 11s, low 12s <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> . Any of those Cobra guys want to disconnect the blower belt <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> ?????

Bob Cosby

Josey....just FYI...."IF" doesn't cut the mustard. "IF" GM did this and "IF" GM does that...what's the point?

As for how much the stock bottom end of the 4.6 will hold remains to be seen. Do you know? If so, please tell us. I don't know, and won't pretend to know.

I have an LS-1 or LT-1. Both will run NA or on NOS and either one has ever lost to no mustang.

I really doubt GM would want a supercharged LS1 from the factory without doing some major revisions to make sure customers won't have the problems you read about in the FI forum right now.

Correction: 613 rwHP and 600 rwTQ on only 16 PSI of boost. And yes, I'm aware of what the Supra can do. Little do you realize that the 4.6 DOHC aluminum blocks made prior to 2003 can also support 800 rwHP, as proven by the likes of a few very hard-core modular racers. Oh yeah, all this GM would of and could have crap won't cut it...the Z28 and Firebird are history (for now), so please don't sing the praises of a utopian motor that GM doesn't even have the interest (or finances) to build.

"Hey Josey, well said. Its only taken ford about 5 years to figure how to make a 32 valve motor work, well sort off, its a pig naturally aspirated so lets put a blower on it and hey were a regular bunch of rocket scientists."

Yes, they are rocket scientists. This car, along with the Z06 are the hottest thing to hit the market ever since the Supra TT and LS1 were introduced in '93 and '98, respectively. A pig, N/A, I don't think so. There are numerous pre-2003 COBRAs with bolt-ons that run between 11.7's and 12.2's, and mind you, this isn't any breaking news.

"I will take a LS-1 car, a bunch of bolt ons and some spray and run that **** over. And you know what if the bottle goes empty I will still be some where in the high 11s, low 12s. Any of those Cobra guys want to disconnect the blower belt?????"

No, the 2003 COBRA owners will keep the blower belt on and let you read their rear plates as they accelerate past you with 613 rwHP of blue oval pride, regardless of whether or not you are spraying. <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" /> And you can spray all you want all day long, but at the end of the day, the 2003's will still be ahead, and our forged short blocks will still be in one piece. I wish I could say the same about your unforged motor after a long day of successive N2O hits. <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />
