I've done a search but it seems nobody has really had any experience with the WMS Sportbox. I'm mainly only considering the Sportbox without the RAF because I don't want to be limited in terms of intercoolers. Has anybody had experiences/opinions/comments with both or the WMS Sportbox alone?

 

Perhaps because not enough people have ever received the Sport Box and RAF. I ordered mine at the end of January and still do not have it. Randy treats this as a hobby now that he flys 6 days a week. It appears he does not have the time to give to Webb Motor Sports that he used to. However the DDM box was originally a Webb box. I don't know what all the differences are other then this new box is larger and is supposed to put out a little more HP.
