I couldn't begin to try to explain this...... you know waaay more about tuning than I do.

I can only say that I stressed to my tuner I wanted a "safe, conservative" tune, rather than trying to max out the HP/TQ numbers. Perhaps this has something to do with it, along with the motor being a stock LS6 other than the blower (no aftermarket cam, no long tube headers, no high flow cats, no aftermarket X-pipe or exhaust).

I used B&B shorties which bolted right up, like changing exhaust manifolds. I did it mostly for looks and a little weight savings to offset some of the blower weight. I left the rest of the exhaust stock Z06.

Thanks Again Hattitude,

Not to be pushy but if you get a chance could you post a picture or two of the hood from top and underneath? Then I won't bug you no more!!!

Thanks,

No problem at all.... I don't have a pic of the underside of the hood, I posted a supercharger pic that shows a portion of the under side of the hood.

If I remember correctly, Adrian said he did something to the under side of the hood to make it look better with the paint, but it was something minor/small. He liked the way the hood turned out.







Whichever way you go, you DO want a supercharger.....

I got a chance to look at a C5 with a KB at Bates Chevrolet where we staged for one leg of the Corvette Caravan. Installation looked beautiful. Hood fit and finish was very good. I checked it out and the hood seemed a little high to me but only from inside the car. I guess you could get used to it, but it seemed to clip off your vision to your right lower section. After being used to the excellent visibility I have from my stock-hooded C5, I'm not sure if I'd go that way. Really, though, it wasn't that bad. I'm sure there will be people who claim I'm full of it and it is no problem at all, that it doesn't cut into your vision one bit, but people can get used to driving a car with a Weiand Blower on it and say its not too bad. Its all a matter of what you want and what you're willing to put up with (think about discussions about how much drone a particular exhaust drones).

Hattitude,

Awesome pictures of your set up; I really like the hood; it looks like that it could have came from GM like that. Blower setup is really clean and I like your mixture of black and polish looks sweet!! I am going to go with their fuel pump system as well because I will be a little more agreesive on the tune while still meeting the CARB issues. Again very, very nice and many thanks for the information I will be ordering mine soon.

You're welcome....... you're gonna love it. Supercharging (of any type) really wakes up a vette.....

The combination black and polished blower is not a normal KB package. It was a special offered by Jeff at TPE (forum vendor) during a KB sale he had back around June '08.

I'm not sure if any other KB vendors have them or even if Jeff gets them that way anymore. Just FYI........

Good Luck....

I think the key is to work with one of the vendors on this forum. Tell them your goals (street, strip, track, or dyno killer) and your wants (I said I was old school, my supercharger HAD to sit on TOP of the engine). Then listen to what they suggest.....

Finally, it is critical to get a good tune, from someone who knows what he's doing.

I lucked out..... I worked with a couple excellent vendors (CMS & TPE) to make mine happen and I am totally pleased. The research was kind of fun too, but the results........ WOW!!

Good Luck whichever way you decide to go...
Regardless of which supercharger you go with, you can easily make north of 500rwhp with stock Ls1/6's on pump gas and retain normal drivability. It's all in what vender/tuner you plan on using and what they recommend based on your end goals.

I have a D1SC Procharger and am very happy with it. I know people with Vortechs, Paxtons, and Maggies as well. Haven't met any of them who wasn't happy with what they had.

Hattitude,

Thanks for your honest opinions. Its refreshing to see a member of the C5 F/I world giving non bias opinions, and not only doing it to please their respective vendor.

Vetteman dan, f you have any questions, or need any specific graphs (or pics) shoot me a PM. I will get them for you.

There are a few other hoods that can be made to work, although I personally love my KB hood.

A properly set up street KB, is sooooo fun to drive. I have never felt a car react the same as a KB car. There is a member on the board (I think his name is powerlabs, but it could have been someone else) that had the opportunity to drive both a centri car, and a KB car the same day, side by side. His opinion, was that although the centri did make more peak power, the KB felt WAAYYY faster. He said it was an indescribeable feeling.

BUT, as Doug at ECS stated, if you use one of their restrictor plates, that does help the low end grunt quite a bit.

But if anyone needs any additional info, lemme know.

I personally had a D1 and F1R. I hated the power delivery so much I pulled it off within 90 days..

Hi Jeff,

You must be the guy that Hattitude was talking about that supplied him his KB setup. I am very interested, well I should say that the KB system is what I am going to buy. I liked the black and polished version that he Hattitude has is that kind of combo still available? I talked to KB and they said that they should get the EO from CARB in 5 months or so. I live in the SF Bay area and have to be legal around here anyway.

They machine this special plate, with a specific orfice. It inserts into the intake tube. It allows you to spin the blower faster, yet restricting the boost to a specific level. By doing this, it makes the centrifugal come in to boost faster. This results in higher bottom end power.

Its a really cool idea.

Well, we are going to be doing a car from the bay area in the next few weeks. Im sure I can arrange a drive for you when its done.

Yes, its still avail. That design is exclusive to us.

Will you be installing the kit yourself?

As far as being bias No! I've had Roots blowers and by no means I'm I saying anything negative, a Roots Comes on like a Mack truck it's basically hit the pedal and it's on! What are some 1/4 times of these Roots cars, just curious. And remember it's just an opinion!

Thanks Jeff,
that about sums it up, simple and effective. Easily removable if or when forged.

So the blower would spin faster all the time?

Sounds like they would use a smaller pulley to make it spin faster earlier and then faster still up top. I would think it would experience back pressure at some point pushing against the restricted opening.

Yes, thus making more boost down low, while the top end is kept in a reasonable amount of boost for a stock bottom end.

We have been using this design for some time now, including in builds like the fastest stock bottom LS1-LS6 and LS2. It is very effective, simple, and expandable without spending additional money to do so.

Oh, please dont think I was making a coment towards you. Actually, I didnt even read your post. I was just mearly thanking Bernie (Hattitude) for giving both the goods AND the bads of the kit, without worrying about making the vendor he purchased from happy. Thats all.

Hopefully that clarifys it.
