Nice looking supercharger kit , Dale- I noted, it cost a bit of $7000 (and 
sold by Mazdatrix which generally sale only proven stuff)  vs $99.00 for the 
Thorton model and both produce approx the same amount of power, Hummmmm.  I 
suspect one of the two does not deliver all it promises - I wonder which one 
{:>)
