Here's my dyno plot from a couple weekends ago. The car pulls hard and is a lot of fun. It could be leaned out a little on the bottom end, but I was getting the car prepped for a track day so I focused primarily on the top end. Trackspeed EFR 6258 kit on a junkyard 03 engine, MSLabs MS3, 3" artech exhaust, flat top manifold, FF 660cc injectors, precision 350hp intercooler. 10-11psi
Nice plot. Next time try to do 2k-redline so it's easier to compare to the "standard".
I'd say that's about as much as you'd ever want on stock rods. Mechanical empathy should allow it to hold up for quite some time.
