I'm going to go with the Torqstorm. Supports up to 700HP which is all I need for the street. Sold my Kenne Bell, it was a cool piece but I want more performance than it can provide. I talked with Torqstorm tech and let them know what I wanted to put it on. They assured me that the 351W kit will bolt on and allow me to keep A/C, power steering but I would have to give up the air pump. This may create a visual inspection issue but I should be able to tune it to pass the sniffer.
From Torqstorm: "Hello Jon
We have a specific 351 kit that would fit better than the Mustang kit. The supercharger will go on the passengers side. The smog pump does need to go. You are going to push on the emissions system pretty hard. The passengers side mount in the lightning makes for a very nice install with a cross flow intercooler. The drivers side throttle body works great. AC and power steering works as it does now. $2950 plus shipping."
What do you guys think? 100% manufactured in the US, I like that.
