    Question Which supercharger would you recommend?

    Looking for recommendations as to which supercharger and/or shop I should go with. I'm in NJ and would prefer to stay with a shop that is reasonable transport or driving distance. Note: This is my daily driver and I'd like maintain a reasonably well behaved vehicle with decent gas mileage unless I have my foot into it.

    So far I'm aware of the Magnuson kit that is coming out but not available yet (or at least I can't find it), the Lund Cadillac Vortec option $7995 box / $9995 installed and the MorePerformanceInc.(MPI) unit that is $7700 installed.

    Lund claims 150+ HP... Not sure if I believe that... Must be at the fly wheel. MPI claims 450-460 RWHP with 6lbs of boost and stock engine. That's a significant increase over the stock lower three hundred RWHP. I'm leaning toward MPI.

    Any other suggestions for super chargers? I'd like to make a decision within the next couple of weeks.

    The short-term plan for upgrading my V is a combination of:
    - Super charger (unit TBD $5K-8K budget)
    - BMR rear wheel hop kit (all three pieces ordered via this group)
    - Corsa exhaust ($1k)
    - Mallet shifter ($350)
    - Lund rear spoiler ($395/Light Platinum - ordered today)

    Heck, I wasn't aware that Lund's kit was available yet, much less pricing.

    Where'd you get the information (not that I'm doubting you) because I'm interested. I'm assuming you mail them the ECU while you install the kit? Intercooled or not?

    More details please!

    Re: Which supercharger would you recommend?

    Here's a excerpt from the email I recieved from Lund today. I also talked to them about some of the other options. They were concerned about the limited market for some of their products (not many Vs out there).

    Email from: Larry Appleby <larrya@lundcadillac.com>
    "THE SUPERCHARGER FOR THE V WILL BE AVAILABLE IN APROX 45 DAYS WE ARE WAITING FOR CUSTOM BRACKETS TO BE COMPLETED. THE COST IS 9,995..00 INSTALLED 7,995.00 BOX SELL.

    THE COST ON THE CORSA DUAL EXAUST INSTALLED IS 1,495.00 (4 WEEKS OUT) SPOILER IS 845.00 PAINTED AND INSTALLED (INSTOCK) WE ALSO HAVE A REAR WHEEL HOP COIL OVER SHOCK KIT INSTALLED FOR 1395.00 (IN STOCK)"

    LARRY


    Sorry I don't have more details now. I'm just starting the search / research.

    The Supercharger timeframe is nearly exactly what they(he) told me about 90 days ago

    Guess we'll have to wait and see. Personally, I hope there is a turnkey DIY s/c kit developed...but I think the LS6 probably is best dyno tuned after such an installation to both maximize performance and minimize problems.

    Keep us posted...I'd LOVE to S/C but will probably do a top end/cam install instead.

    Re: Which supercharger would you recommend?

    I agree with the dynoing. That's why I'm leaning toward MorePerformanceInc.com. They do a before and after dyno. And the Stage 1 kit will give me a little more zoom zoom, not require extensive engine mod and keep the car whole as a daily driver.

    My thoughts exactly.

    Cool Re: Which supercharger would you recommend?

    I spoke with Chuck Mallet about 1 1/2 mo's ago and he said that even at 6lbs of boost with the MPI supercharger, the bottom needs to be built up(stroked I believe). Maybe he's just saying that for his sake... any experts out there on what would be reliable supercharger with no bottom end re-build? Also, which of the superchargers gives you the top end power. I think that is were this car lags... a supercharger working more in the 4k RPM range and up is what I would like to see.

    Vedder,

    Storked refers to increasing displacement through a stroker kit... which is not required to beef up the bottom end, although perhaps a consideration if you're in there anyhow.

    He has seen stock Z06 motors fail running 6psi... that's why he says that... Basically anything over +100rwhp on a stock motor makes him nervous...

    Re: Which supercharger would you recommend?

    When speaking to Mike at More Performance Inc, he told me they've put 4K miles on a stage 1 upgraded stock engine with no issues. Anything beyond the 6lbs of boost (stage 2 & 3) would require engine modifications.

    I'm a novice in this area and can't justify any of the claims. If anyone feels I'm making a mistake heading in that direction PLEASE let me know before I fall off the cliff (so to speak).

    Lingenfelter doesn't share Mallett's concerns about running a low boost Magnusson blower on a LS6 as witnessed by their Z06 program... But different tuners, different concerns.

    Re: Which supercharger would you recommend?

    If you are serious about more power, definitely give a call to Ligenfelter and see what they can do for you. Most likely Ligenfelter would install a Magnuson Radix blower if that was your choice - pick their brains, see what they recommend.

    Remember, all it takes is money to go fast.

    Scott,

    East Coast Supercharging in Cream Ridge will do the ATI Procharger install for around $8-9k you'll have to call Chris and get a quote. I can refer you if you like, that way if it comes out good I'll get him to knock some money off my various pending installs.

    They do mag superchargers too there. Good quality work and they will do the dyno tune etc for you as well. I have had all my work done there so far for even minor stuff and it's good.

    The ATI is the way to go in my opinion, it's intercooled (the cheap kits are not) and if you rebuild the bottom end you can crank the boost up to 18-20psi no problem and be pushing ridiculous rwhp.

    If you want to get in contact with me I am in south NJ, drop me a PM and I can set you up with what I spent a month or two learning about CTS-V tuning in our area.

    Re: Which supercharger would you recommend?

    Superchargers usually increase given engine Horse Power by about 33%. There is a Supercharger that will increase Horse Power by 50%. It is the Whipple Supercharger. The reason is that Whipple builds a Screw-Type supercharger compressor which operates adiabatically. This means the pressure increase is achieved with almost no increase in temperature. The best way to increase horsepower is to inject a cold air charge. The specific power output is raised. Just installing a lower temperature thermostat will give a cheap power increased. However, your engine computer is deceived to run as if your car is operating from a cold start continuously. The computer will set timing inappropriately, increasing emissions. When the older design lobe type superchargers increase inlet pressure, they significantly raise air charge temperature. This greatly reduces the effective gain since the hotter air charge is less dense, limiting the relative gain.
