Im going to have a pretty hefty tax refund this year, and am dreaming of a 402 KB in my RX7.

Anyone have any good info on the LS1 KB?

A few specific questions:

Will it be CARB legal?

Is it any longer than the stock intake (trying to figure out how much I need to cut my cowl)

With a mild cam, and tuning for crappy california 91 octane, on a 9:1 motor, how much boost could I be running, ballpark, and what kind of numbers would I expect? Around 600/600 at the wheels?

I also have a standing offer to have my car shot for a national magazine, but would like to wait till the car is a beast before shooting, any shops doing any sponsorship or introductory pricing?

lol.....Kenne Bell is an idiot

Go to the Corvetteforum and see what they think of him there

 

They just think that cause they cant have one.... too many cobra taillights.. wait til he releases them, maggie galore will be for sale.... Im waiting on one for my malibu, may check out the beast whipple has too....

 

Most of the Corvette people would rather have an ATI, Vortech, or NOVI unit. It isn't that they don't like the KB setup, it just that KB doesn't care about Corvette enough to get a product out there and support it.

But I have seen the KB setup in person and it is very very very nice looking. I believe you might beable to get one from a non sponser that I don't think they would like to be naming. They had a KB setup at SEMA. PM me if you would like the name of the place.

That setup makes for one hell of a "Turn Key Engine".

 

For Vettes, there is only the Mag and Turbo Kits... the Novi, ATI, that's all a waste of time, IMO. For LS1 F-body's that can't mount Roots or Twin Screws, they have to get centrifugal SC's... they have no choice. Why waste the good options Vette's have with centri SC's?

 

[QUOTE=BLWN1]They just think that cause they cant have one.... QUOTE]

Not exactly sure what your saying there, but KB was/is (who the hell knows) making a kit for the C5. I forgot the Corvette Forum member's name, but he sent his car to them about a year ago (maybe more) his car was moving along at an ok pace, and then apparently something happened and KB ended up buying the guys car and no one knows what is going on.....

 

[QUOTE=2002 Trans Am]So therefore, no one has one, still correct? While the 03-4 cobras are spanking ls1 *** with them? They are getting tired of waiting and getting beat. When or if they do come out, it will be like sliced bread all over.

On another note, I think I would rather have the novi, vortech or ati over the maggie..not sure why they would be a waste of time, may check numbers on those....?

 

Honestly, I forget the maggie's early limits... Obviously a D-1 or equivalent will produce the numbers, I know that, with a crappy looking curve, IMO. Look at the powerband of a Twin Screw/Roots motor with 600 rwhp and a centrifugal SC motor with 600 rwhp. You might want to check those....?

The selection of blowers is not that much better than I thought over F-bodies. It escapes me why they don't have a better selection of blowers, why they don't have more aggressive Roots or Twin Screws... Corvette guys? Why is this?

 

I love centri but Im waiting to see if KB will help me out... we'll see

 

[QUOTE=BLWN1]I have never had a 03-04 cobra any near in front of me. The only thing they have seen is my tail lights for a second anyways as I pull the **** out them . I raced a 04 cobra with a KB and he said he made 625RWHP and 670RWTQ and walked him like he hit the damn brakes. The cobras problem is weight. I'm not trying to take away from the cobras, but it takes a blower to stay with a bolt on LS1. Thats just my 2cents. Not trying to start a bunch of crap, but that has been my experience.

 

Maybe because they don't need a better selection. They (we) have the maggie, but that's about it for roots/TS. The maggie has a good following, but it doesn't make serious power (<575 rwhp, the norm being about 470).

For those not impressed with the dyno sheets or curves from a worked centrifugal C5 obviously have never been in one. Almost all of the CSC kits for the C5 are light years better than the SC crap the F body guys have. I can assure you most of the vette kits have the potential to waste any non-spraying KB Cobra, and many of the turbo kits the f body guys have as well. For those who don't believe me take a trip over to the CF and look in the FI section at the numbers these guys are generating. Also keep in mind they have a significant weight advantage over the Cobras and F bodies. I'm not saying the vettes are a better platform, but to say the CSC C5's can't compare to KB Cobras or F body turbo kits is just plain asinine. Hell, I know for a fact that ECS will have several 8 second street C5's at the track very soon using basic Novi 2000 ECS SC kits, just waiting for the weather to brake and the tracks to open. Geez, come to think of it, when I had the A&A SC kit on my stock LS6 Z06, not once did any Cobra or and other car ever come close to being able to keep up with me. Alfred's 800+rwhp turbo SS was the only car that ever pulled me at all. Don't knock the C5 CSC kits if you've never seen their true potential, they can be VERY impressive and I don't see any TS kit being able to beat them on the street or at the track anytime soon.

KB has been promising their release of the C5 kit for a long time. Dates have come and gone to many times to count, which has left a really bad taste in most peoples mouths. All the guys that were waiting for the C5 KB kits have pretty much said FU to KB and have purchased CSC or TT kits. As mentioned above, Rudy let KB prototype with his C5 and after a year w/o results they had to buy the car from him. From what I understand they've had some major problems with the manifold and have had to go back to have it redesigned. My guess is they MIGHT make it to market around next summer.

 

I agree with everything you said, they have a growing turbo kit segment, too. But to say they "don't need a better selection." Hell, they don't NEED any of the SC's, even the ones they have now. The SC's out right now are FINE but could be better. You could argue platform... I'm talking SC's. I think Mustangs have alot better blower selection anyday. Corvette times are faster? Of course, they can be even faster, though. You have F-body guys cutting the cowl doing PITA work and making them fit. With the Vette, you would just need a bigger hood maybe... it's so much easier. Look at the Mag. Why don't they make upgraded units? Who is this Corvette market made of?

 

Here is a link with a picture of my supercharged LS1. www.s-clusive.com/roger.htm

As you can see it is the same supercharger that Kenne Belle uses. The manufacturer is Autorotor out of Sweden. Kenne Belle I believe has the US rights to this supercharger for Ford products. Perhaps the reason he is taking so long is he is trying to get the rights for all GM products too. no proof on this just a thought

 

Why didnt you mount it in the bed.. lol

How does that worK?

 

For the topic of KB's on LSx motors. Here is a pic

 

I am very sure the KB is taller than a LS1 intake, so you will need to do some modifying.

There are a few reasons why the KB for the C5 might not be popular, the required hood is certainly one of them.

They make a great kit, I did an install of one on a mustang, and it was a very well thought out kit, making good power.

Zowee! That smarts the eyes it is sooo shiny! Pretty sweet picture.

Is one able to control boost (ie ramp it in instead of instant whammo) with a supercharger just like a turbo with an advanced electronic boost controller?

Bleed off valve? For any hope of traction with one of these on top of a 402 with heads that breathed ok?

I come from the Buick GN clan originally and even with measly flowing 210cfm intake fully ported iron heads and a TE-63 turbo you could still make 700fwhp+! The power of forced induction can solve inefficient cylinder head flow pretty easily.

A $3800 402 shortblock with $1K 6.0 budget ported heads and even small a cam breathed on by a supercharger would be a serious machine! I'd imagine 700rwhp on 91 octane and splash of methonal injection would be pretty easy to make.

What is initial pricing of the KB unit supposed to be? Over $5K? That is a chunk of change but compared to some twin turbo setups it may be comparable.

 

Dayum...

 

This is true, but most modded vettes (well ones that go for that much hp) have aftermarket hoods. And if you where going from a Magi to this, the same hood would work.

 

The KB unit is taller and Magnussen hood will not work at all. When and if, Kenne Bell is ready to deliver C5 units to market, they will. Jim seriously takes his time. You might be waiting a little bit.
