We use the A&A supercharger kit. Blower alone it will make 570-590 rwhp on a Z. it will cost $8200 installed and tuned(Street and Dyno)

Our Stage 4 Kit will make 560-580 rwhp and cost $7800 Installed, Street Tuned and Dyno Tuned.

Stage 4 Includes- Lethal or Stalker Cam, MTI Racing LS7 Heads, LG Headers, Calloway Intake, RR-Ported Intake and TB, 160 Stat, LS7 Gasket Package.

The Cost difference is not that much and you can see that the Stage 4 is actually cheaper.

Just some food for thought.

When you add heads you can get 550-560rwhp with stock drivabiliy oout of our Stalker Cam. You can get excellent drivability 570rwhp with our Lethal.

So what it gives you is more power withour having to cam in the car that doesn't drive the greatest. The heads are worth 28-32 rwhp.

I promise you the Lethal cam is not a big cam. I have tested several. I am sure if you want to see 600 rwhp then I can put on the short belt, and an electric water pump, Ice down the intake....and all that good stuff and I could pump out a number. I am sure that would sell my product. Too bad when the customer goes to have it checked at another shop it will be down 25hp from what I told them it had.
On a side note. Now that we have our own in-ground dyno and have a weather station that is out in the open like our cars and not stuffed up against a shop wall that radiates heat (as I see in a lot of dyno shops) we are finding that our numbers have been very accurate. I'll take my true 575rwhp numbers all day long and be respected for being truthful. My numbers aren't the best, but they are correct. You also don't see me parading around hiding my cam specs either. When you get a product from Ragin' Racin' it performs as advertised and you know what you bought before you recieve it.

BTW the car did do 600rwhp uncorrected!!
