Ok, changing up the build a little. I've decided to run a single s480 double batmowheel instead of just upgrading the low pressure turbo. I do have gurus plans for fuel. Maybe the cp3 kit if it ever comes out. Dropping the truck off at Rudys this week to do s480 single kit (manifolds, up pipes, down pipe and intake), intake elbow, intercooler pipe, porter fuel rails and head gaskets. Since I'm running the Spartan I'm hoping to get some custom tunning done by River City Diesel to maybe help the spool up. What do you guys think this setup will be capable of at the track? I've pulled 1.64 60" times before so I have the traction. Would like to run a 12 flat. We will see! I'll keep you guys posted!
