Thats the nice part about the Supercharger. I up the boosth to 12 to 15 and have well over 1000HP when ever I need it.
Of course I don't ever see the need for that much. 
Apart from making me feel VERY jealous, too much power? i did know of a chap that had an ex drag engine in his chevvy putting out over 1000 bhp, he thought it would be fun to take it to his local pub.
When he went inside the landlord told him that if he ever drove the car in there again hed be barred for life!
Apparently it shoook all the glasses off the shelves!

Id so love to supercharge or turbo mine, but i need to find some more monies! Oh and id have to lower the compression, shes running at about 10:1 at the mo.
