Man I was kind of disappointed when I talked with them this morning. I called them up to ask if the 3.5L supercharger would work on the 4.0L and they said no. I asked them if they were going to come up with one and they said no. They are only going to support the 350Z and the Titan since they said that they were working on one for the 5.6L. They are not interested in doing one at all for the 4.0L. That sucks. Man we really need to tell them to make one because there is a lot of interest. If I could get one I would buy one for sure.
