Which Dart heads did you use? I ask because I have to port match them to the Whipple intake. Not a very good match stock. Did you do this? I am running the Pro one seris.

Jeff I used the cnc ported 335 heads, I did not match the ports when installed, but I am currently building a 557 quadrotor with the dart cnc 355 heads and I will certainly see how they match up(or don't match up?)FYI we spoke briefly before you installed your whipple, Rob at HTG is building the 557.

Oh, O.K. cool, question, did you look into the 5.0 whipple? Instead of the quad rotor? Also, tell Rob to double check your push rods apone assembly....;-)

On the Whipple kits They are made for/into the lower intake. I wouldnt run it without a innercooler.

I am hearing the 5.0 is a lot more money that the Quad?

Whipples are awesome blowers. I have about 100hrs on a pair of 3.3s, no problems so far. They sound really cool when they are making boost

Still learning about blowers and things like that. We're doing some maintenance on our blowers this winter and Rob's been great in explaining everything and what it does along the way. Just helps me understand a little bit better when you goes start talking your talk!
By running lean, I don't mean intentionally jetting lean. I mean having something go wrong and disturb fuel delivery to your cylinders. Something as small as a piece of dirt or a failing pump can restrict fuel supply- it only takes a few seconds to go from smooth running to Chernobyl inside your motor. There's a very fine line between max performance and meltdown with forced induction.

Maintenance, diligence and a willingness to replace some key parts even though they're still working is the only way to successfully live with blowers.

I'm anxious to try this on the set of motors I'm building now. If iot does half of what they claim and what people have said it does, it's worth the $$ just for the meltdown insurance, let alone the performance gains.

Jeff I did look at the 5.0 whipple but since I will have to modify the rear hatch regardless of which one I went with and they are both capable of 1000hp on pump gas(93 octane) I went with the quadrotor, I just like the looks better. Larry
