Guys, a lot of the cost you are paying for in motors like these is the engineering hours and testing of the materials/parts used to verify power output is well within spec of the motor. You can go to other builders who can put together all of the right parts and have a hell of a motor that will likely last a very long time. However, those builders have NOT done an engineering analysis and analyzed every piece of the motor under controlled tests. These costs are quite expensive.
Also, lets not forget that Katech is a highly respected and one of the foremost authorities in the LSX market. They have sufficient media exposure as well, so they can charge a higher premium based on these factors. If you could sell a product at a higher premium based on your quality and reputation, why wouldn't you do it? After all, you spent all of those hard earned dollars before on quality equipment, the correct staff, and an appropriate test regime.

Just for giggles, how much is that supercharger, without the LIM/Intercooler plate? Just the base supercharger.
Reason being is that's the first forward inlet SC I've seen with the pulleys actually attatched to the SC itself and not the adaptor plate. Makes it a viable candidate for some other platforms...

I can see you still covering after 91 days, its when something happens after 5months and you have a pile of metal that is 100% useless. Its just nice to have piece of mind for more than 90 days after spending basically $40,000 for just 580 RWHP. But I do understand you cannot be responsible for how people install and tune the crate engines. Cam/port/exhaust/tune LS7's are making more power than 580 RWHP and still covered under warranty at dealerships. At least around here they are.
~725 FWHP = about 580 RWHP through an A4...right? (20% loss)
Nice engine but man you can build two amazing N/A 454's for that price though.

If something happens after 5 months that was a defect on our part there is still a possibility we would cover it. We would handle an issue like that on a case by case basis. If the only reason you would not purchase the engine from us is because you are worried about the engine after 5 months, I don't think you understand our reputation. If you want piece of mind, base it upon our reputation, not a piece of paper.
Cam/port/exhaust/tune LS7s are not making 580rwhp through an automatic. In my opinion I don't think they're making 580rwhp at all. If you don't agree bring one over to our chassis dyno and I'll show you. That is an seperate argument all together. These rwhp numbers I've been seeing on the internet are laughable and ruining everybody's perception.
As far as the warranty, GM put out a bulletin regarding aftermarket tuning. Any time you tune the computer, you void the warranty. If you want to read about it, go here: http://forums.corvetteforum.com/show....php?t=1981426
GM will not cover any powertrain components if an aftermarket calibration is present in the PCM. GM will also not cover powertrain warranty if the vehicle is equipped with a cam, headers, or other aftermarket components and the service manager or zone rep has reason to believe that the aftermarket modifications contributed to the failure. If a dealer is telling you that they cover modified engines they are either lying to you, misinformed, or fraudulently submitting warranty claims to GM.

How do these other builders know they are putting the right parts together? They don't. They are guessing. They don't have the engineering background to test and validate combinations. This is the piece of mind included when you buy a Katech engine.
You're right, we do have higher media exposure, but we don't charge a premium for that. Our advertising budget as a percentage of sales is in line, if not lower than most companies. We just have a great PR company that does good work for us and makes the connection between us and magazine writers.

Thanks Jason. I looked around Magnuson's website and the closest design is the Mustang and F-150 setup. Not too important. It'll come up on their site in due time.
It's just nice having the superchager pulleys actually attached to the housing, not like the other corvette and GTO SC's were designed.

Keep in mind that the Dart billet block for $9000 that you mentioned is the one sold directly from Dart. We made 32 design changes from that to make the 500.[/QUOTE]
Jason, is your darton block available seperately?

But...don't get me wrong, I'd love to have a Katech engine in my car, anyone that wouldn't is kind of dumb, you guys are top notch.
Its just a shame that you literally need to be rich to have these types of set-ups from shops like yours, so 99% of us cannot play along. The engine is about $10,000 more than we paid for our cars.
I will be, and probably alot of people here too, will be curious to know how many of these you sell over the next year.
It also kind of sucks that we can't get the 12 mon/12,000 mile warranty, because almost everyone here would want to put it in a late model 1998-2002F-Body or Vette, not an old muscle car, and you won't install it in a late model because of emmissions. If I had an old muscle car I'd rather put a BBC in it for less then half the price that makes 200-300 more HP, with a 12 mon/12,000 mile warranty from a place like Fast Time Motorworks. Old muscle and BBC just go together.
Cheers though

I have an APS STAGE 2 Twin Turbo kit that is made for a 427. I think with race gas this kit is rated at about 1000-1100 hp at the wheels. How much power can this LS7 block take ? Would you recommend the C5R block instead of the LS7 block ?
Does KATECH ever have a huge sale on these engines ???
P.S. You can just gimme one of these engines and I will PLASTER KATECH stickers all over my car!!!

This appears a great engine but the cost is just more than most can spend. Consider that you can get a 750 hp Scott Shafiroff Ultrastreet 588 BBC for around $12.5K. Hell, for an extra $4K you can even get an aluminum block. Granted will take some effort to wedge into a Gen IV but this engine has a much longer warranty and you can use the extra $30K for parts. Something to consider....

katech performance announces 'air attack' ls7 supercharged engine package
clinton township, mich. - katech performance has announced its "air attack" ls7 sc (supercharged) crate engine is available for owners of hot rods, off-road vehicles and show cars.
The 427 cubic-inch displacement (4.125-inch bore; 4.000-inch stroke) engine produces up to 750 horsepower and 700 ft.-lbs. Of massive stump-pulling, flat-lined torque. Katech lays a solid foundation with callies forged steel crankshaft and connecting rods plus the manufacturer's forged aluminum pistons with dlc (diamond-like carbon) coated pins. They use a stock ls7 block with a billet steel girdle to tie the bottom end together.
"our air attack ls7 sc delivers extreme forced-induction performance for the ls7 engine in off-road and hot-rodding applications," said caleb newman, vice president, director aftermarket operations, katech performance. "because we are producing 50 percent more power - far beyond what the cast production piston was designed for - our katech forged pistons were a must in the air attack ls7 sc to maintain engine life and enable even greater boost levels."
an upgraded camshaft designed for boost actuates the stock ls7 titanium intake valve and sodium-filled exhaust valves. Magnuson handles the compression of the air change with their m122 twin-screw high-helix intercooled supercharger. In addition to the standard features, optional katech valve covers and tvs-based superchargers are also available.
The engine is one of five that make up katech performance's ls7 "arsenal" that includes a "street attack" ls7 7.0l, "sneak attack" ls7 5.7l, "desert attack" ls7 7.0l and "track attack" ls7 7.0l option. Each engine is completely disassembled, blueprinted and enhanced by the same technicians that produce championship winning engines for all katech race programs.
Since 1977, katech has captured more than 50 driver's and manufacturer's championships competing in the world's most prestigious racing leagues, including the scca speed world challenge, american speed association (asa), international motor sports association (imsa), american le mans series (alms) and nascar(r).

Impressive but for my $40K I'd have to consider another choice. Why not try a 582 low deck BBC. Can get these with around 750 hp for less than $14K complete with dyno tune. More work to put in but a little easier on wallet.
