Cobra R - I highly recommend the 19 lb Whipple with the HP/Shadowman tune for 91 octane. It's more like $15K & 190 hp. When you get it you'll kick yourself for not getting it sooner. Bony told me to skip the pully/tune & go straight to the Whipple/tune. He was right! I love the power! It's unreal. Ask Tim & his kids or Stormcat (my passenger's at the Rally).

PS The 15 lb has an approved CA EO #
I'll attest to that!! It's a real G machine !!
