Finally got a chance to lay the hammer down on the dyno with the baby turbo. 2009+ 5.7 hemi with drop in forged pistons/rods. 80 lb injectors, dual Walbro 255s, Holley HP EFI, Bullseye Street Billet S366. With the gate slammed shut it made 17 psi peak until it choked out and tapered down to 12 by the end of the pull. Normally makes peak power at 5500 at lower boost but only 4600 this way, severely turbo limited. Pretty surprised, didn't expect 700 whp this easy. It could make more if I pulled some fuel but I was thrilled with 720.

The little budget 5.7 keeps on surprising me.
