Additional considerations when supercharging
Hello,
I am Planning on doing the A&A kit on my C5 in the next few weeks. the car has 95k miles and is running great. I am wondering on what additional cost or expenses are involved. I know I will have to plan on replacing the clutch at somepoint. Is there any thing else to consider. A vendor told me the stock crankshaft pulley is not very good and I should plan on replacing that at the time of the install. Also, it was mentioned that the radiator be upgraded. I will be staying with a safe tune and will be hoping for around 500 RWHP. I will probably stay with this untill I am ready to pull the engine and go forged.
Any help would be appreciated.

Some additional considerations for your build:
thats all that comes to mind for now, enjoy!
- applying locktite to the camshaft bolts
- changing or upgrading the stock harmonic balancer
- upgrading clutch
- check your prop shaft bushings
- adding a remote bleeder to your clutch
- throw out bearing, slave, master
- alky kit
- boost gauge
- headers
- spark plug wires may fall apart when removed (mine did)
thats all that comes to mind for now, enjoy!

You may need to replace the valve springs also. I added an A&A kit with a 3.6" pulley on my LS1 and the motor made 478 hp at 5700 rpm on the first dyno run, which was a bit disappointing. This was due to the intake valves not being able to hold the boost pressure from the blower. The motor had less than 14,000 mile on it at the time. A set of PAC 1518 beehive valve springs were installed and the motor then made 498 hp at 6000 rpm on the next run. The tune is very conservative because I don't have alcohol injection and the car was tuned to be California smog legal.
Not sure why the radiator would need to be upgraded. My car does not run any hotter now than it did before the blower install. In fact, below 2500 rpm it runs exactly like it did before the install.
