July so far ,i got an email from them may 8th, here it is:
We have done a Predator already and are trying to get another one in here to R&D the hardware kit. We made 3 horsepower over the stock carb. The carb will be machined to the same dimensions as the stock carb to fit the manifold and air box, so your filter will fit onto this carb. Cost should be in the $500.00 range at retail.
We hope to have kits out in July.
