Pretty much nothing touches the throttle response and sound of these roots blown combos. They make torque instantly and have a look that no other can replace. If you’re a blower guy, you can’t be converted. This engine has low compression and hydraulic roller camshaft so it can be cruised on the street using 91 octane pump fuel and be able to put a bunch of street miles on it. You’ll be able to hear this motor from two blocks away.

"Tom it's been a couple years now and I just wanted you to know how much I enjoy this engine. The sounds that come from this engine are pure MAGIC. I love the surge at idle and the blower whine. You can hear me coming from a block away and when I snap the throttle It sounds like its a mini Top fuel engine on the street. It really is an experience to drive it. Thank you for building me my dream motor."
