is going to start being a new trend lol. This is classic fuel pump failure when you see black inside the filter sock its not from dirty fuel its from the pump eating itself internally. We have seen several from a company i won't name but we see this even more on boost a pump cars. Becaus3 your over driving the pump it will eventually fail. If you don't catch it soon enough it will cost you a motor. Every. Single. Time

Enjoy your weekend!!!

A killer combo getting added to Mark's hellcat. He previously did a cam and our 91 package after a lifter failed. Now its going e85, ported snout, and 108mm throttle body.

Want to take you blower to the next level, but don't want the down time??? Now offering billet bearing plate installs in house. Who wants to wait 3 weeks when it can be done in a day. This is essential for those builds looking for 1000whp+.
If you already have a ported snout and 108mm throttle body this will give you the edge over your competitors.
