If that is your engine pictured in your avatar, then we see that you have an old Whipple AR1600 with no possibility of adding a cooler to it, besides meth/water spray.
6 pounds of boost makes you want more for sure.
If that engine is a 3.0 liter, then you are in luck.
You can get the next smaller pulley and get about 8 pounds of boost.(4.0")
You can get the next smaller pulley to that and get about 9.5 like I have.(3.8")
You can get the smallest pulley and get 10-10.5 pounds like Ed has.(3.6")
With this you will need the injectors, Fic, Harness, 1:1 fuel pressure regulator, new clutch eventually, at least one wide band to monitor all the time, a fuel pressure gauge is nice as well.
Another important thing to have is a return ticket for Dave the Doz to come visit you and tune that animal....lol. I am still collecting Air Miles!
