Need Advice on Adding More Power to HPS SC
Looks like there is still a little rubbing in the rear left so I have to get the Cambar kit as well as a set of Sway bars. Let me know what kind of pricing your buddy can get them for. I got quoted $150 to machine the H&R 10mil spacers you gave me. I think you can get it done cheaper.

Also Rob sway bars wont do ANYthing to stop rubbing. Thats one of the funnier things I have come across but its a bunch of hokey. The camber could fix it but you will need speedybenz camber links, rear renntech subframe upgrades, or a set of K-mac bushings to chance camber on the rar axle.
E-mail me.

What are the affects of not having a level car (balance, handling,etc..) other than any noticeable visual differences?

BTW...My drive belt broke off while I was doing 80mph on the 57fwy N at 9pm after leaving work. Steering wheel locked up after the alternator shut down. Turns out the SC idler pulley siezed up and burned up my belt. Man was that scary.
Got the car towed to my house for $81 and another $350 to tow it down to Mechtech in Escondido. You see how the costs just keep adding up? I bought the belt online for $55 but now I need to buy more parts like the idler pulley, etc..plus labor. I am now ready to swap out the SC for a TT!! Now I'm in a rental again for up to 2 weeks or more if I go with a TT setup.

It doesn't sound like normal wear n' tear?

Mind you, there are quite a few obvious structural differences between them. And Im sure Kleemanns programming is a bit more studdied and avanced, but the heart of the system is identical.
Now, I acknoledge that HPS has had some technical issues when first introducing their system. But it does comfort me alot more now that one of the biggest MB tuners just decided to share the same company's Supercharger in thier units as well.
I've posted pics of their recently re designed system with a link to Kleemann's site.

Thericker, their application list will obviously be different because their new system is designed for the new 2007 550 motors, whereas HPS's was designed for the M113 engine.
Your right about Kleemann having greater power up in the higher rpms. Personally, I do most of my driving in the 2500-4500rpms, so having the power down low was my preference. Thus my decision was made easier by going with HPS's design. If Kleemann was using this type of blower before, then it might have been a different story.
I think kleemann products are totaly awsome, and I'm glad that their using the same blower that I have currenlty installed. Like I said before, it gives me peice of mind.

They will heavily subsidize the development costs and my out-of-pocket upgrade costs will be minimal. Jim is confident it will be more powerful than the new Kleemann kits but we shall see. If this kit is successful then MT will make it commercial.
I'm glad Jim is willing to take the initiative that HPS refused. I will refraim from posting daily or weekly until the entire project is completed and the kit is fully tried and tested to work reliably and with the estimated power gain of 75-100rwhp more than the Gen II. Hopefully this kit will push me over the 485rwhp mark! The project is slated to start once the blower comes in next week.

Good luck w/mp122 don't say I didn't warn you, they have scrapped the devlopment for Vette applications, due to bigger MP122 making LESS hp torque, than mp112, also are you getting a CARB certification w/this install?
I seriously doubt you'll be able to ever pass the sniffer...Once again good luck!
But there is a point of diminishing returns, I believe you've passed it, why not go w/Jessies TT project? Or OVERLY proven Kleeman application?
Edit: The MP122 was designed for the LS2 or whatever application, to boost motors further that have internal Heads, Cam, etc.. Modifications, and found thru extensive testing to produce zero extra power on an otherwise stock application w/MP112, and infact made less hp w/equally modded MP112 LS2 engine. Go look it up on Corvetteforum.com
Just trying to prevent you from further disapointments

On M273 application, with it's significatly better flowing 4-valve heads vs. 3-valve heads of M112/113 and running only 4-6 psi, both deisgns would be very close in efficiency. At higher boost level, is where Lysholm exceeds Eaton.
