I am getting pretty close to running my car on the dyno for tuning. I am wondering if you guys would know if my fuel system to withstand the power levels I should achieve. Right now my current fuel system is Walbro GSS340, with a procharger inline pump, areomotive regulator, and 85lb fast fuel injectors. My setup is a lsx376 crate motor,Whiplash II camshaft 24X/25X, D1sc procharger between 8-10psi, 2" hawks headers, 92mm throttle body, through a 4l60 with a 3400 stall. I am guessing it should make somewhere close to 700rwhp or more.

 

Sounds like you have a stout setup,but really the dyno is meant to dial it in and see if any problems come up.The tuner and dyno operator should see if you start starving for fuel and stop the pull..make adjustments and try again.

Good luck and keep up updated on results.Nice setup

 

Some have gotten away with 700rwhp others starve at a little over 600rwhp. Why not DIY twin pump to be on the safe side and be ready to safely turn up the boost at the dyno session?

definitely sounds like a good idea!
