Just because JH or DC uses it does not mean its ok. I know those guys know better then that! They are probably using a booster pump or "twin" 255's. FMU is only a Band-Aid. It is a very cheap way of avoiding a fuel system.

Yea its beginning to melt the pistons! lean spikes of 14/1 A/F :mad:

The 255 pump is not near enough fuel! period! He is LOSING FUEL PRESSURE when the boost comes up! The truck is going LEAN! The single 255 pump is good to about 580 or so RWHP. His truck WILL be corrected :star:

Dude those trucks are CAKE!! We have done a few 522s with blower upgrades.. No one has had the balls to let me TT a Viper Truck yet. But when it happens it will be the badest MOFO:D like our Vipers.. :star:

Thanks man... Kc did the video.

Here is a link to that video of the red Viper at the track for the first time. Only 20psi of boost with a 10.0 A/F. Track closed and we had to send the car back to Vegas. http://www.speedcraving.com/extreme/viper/garths-viper.wmv
