Not far off, but you're constantly doing stuff so....why spend that money with a maxxed performance benefit. After the cart is properly just behind the horse, closely study your budget, and save for a blower upgrade with fuel system upgrades, running on E85. Or put it on your bucket list for future consideration. JMO.So with E85 what's a good number to expect 600whp?
E85
Ported blower
Cams
Tune
I'm not an expert on this stuff.
