What is a csc? Catylytic Super Converter?
Seriously though, what is it?
I emailed Intense today and they told me to look at the 3rd generation rockers. They would cost 400$. And from what I read I can probably get well over 30hp at both wheels and crank. 30 more hp, that is pretty noticeable, right? Were talking quicker acceleration off the line and more power on the interstate...? What about gas mileage and maintence?

csc = centrifugal supercharger

Rockers would give you about 20-23 whp or 30crank hp. Mileage will most likely increase a mpg or 2. You will notice the power especially in the upper rpm range.

csc=centrifugal supercharger. Think of only one turbo turbine attached to your accessory belt. zzp sells a kit for GPs. Think about what a change your intake/exhaust made, and that was probably 10 hp. Now try to imagine 30 Rockers would give you a little bit of help down low, but most of their effectiveness is up high in the RPM range. You might want to think about new, stiffer springs with the rockers while you have that all dissassembled.

That CSC kit looks sweet. If I had another car and money that would be cool to put on. More power in the upper RPM range, like around 4k and beyond? Whats out there that will give me more power in the lower RPM range...a custom chip? When both of you say wheels and crank, which one makes the difference on the road? When a car gets dyno'd, does it measure wheels, crank or both?

The CSC is MUCH better at high RPM then the roots style blower that you see on L67'*. It'* more effecient, and doesn't fall off like the roots.

Dymo will show wheel horsepower. Car companies will list HP raiting in crank. Typically for our cars we say the drivetrain causes 20 percent loss in HP to the wheels. So to get crank hp you would divide whp by .8. To get whp you would multiply crankhp by .8.

I see alot of recommendations on ported exhaust.....is there info on doing the porting?
Who sells the ported exhaust for a Bonneville

with an SSEi it would be better to get headers, but an NA should probably port the front one, as the back one cannot be ported.

Correct.

Headers will work great on any car. N/A v8'* have always done this, works the same for v6'*
