Is this a gasoline setup? I sure the heck hope it's not alky.
If it is alky, you need 2 things.
1. A bigger pump... something in the 8-10 GPM range.
2. A better ignition, that 7AL aint gonna cut it.
Now, if you're just wanting something to play with on the street and look cool, you can under drive the blower and make what you have work.
If you want to race, and make some decent power, that pump and ignition has to go.
If you want to talk directly about this, PM me your ph#.
