If you limit the boost(I would stop at 5 to 7.0 lbs.) and tune it so it won't ever detonate you may be able to have some fun while you save for the next, better build for the supercharger.
I would look at one of the water and methanol injection adder kits(Snow brand maybe?) under boost for added protection also
Don't forget that the carb. needs converting for the blow through application, don't try running it without that!
