700+ rwhp at 22psi with E85...C6Zhombre or Sleeper04 can attest to that. People that say you have to buy a VMP to get there have drank too much kool-aid
I have ran 107mph in the 1/8th with my 2.3 @20 psi and E70. HP calculators came out just shy of 680rwhp. Was 678rwhp. Still had stock manifolds on the car. The 2.3 Whipple is a great blower.
