      Here's my setup:

      Stock Bottom End ( Rods with ARP )
      SPA Head Gasket Spacer - 8.5 compression ratio - Copper o-ring
      Stock intake manifold
      ARP Head Bolts
      SPA Turbo Manifold T4
      Holset 66mm x 64mm Turbo AR .86 T4 Hot side - .70 Cold Side
      Fueltech FT500 semi-sequential - Custom Map
      1200cc Injectors Running E100
      Walbro 450

      I've made 430whp @ 1.7bar ( 24psi )

      Point is - I'm currently looking for +550whp - but not sure if i'll be able to get there with the stock manifold and head.

      Is it necessary to have camshafts, larger valves and ported head to achieve that number?

      I would like to hear from you guys.

      Thanks

      Power seems a little low for e85, we get that much on pump gas without issues. Likely needs timing adjusted, but will be low 30s psi for 550whp.

      Timing if anything looks aggressive. You can loose power from too much even without knock.

      Also verify WITH A TIMING LIGHT that when timing is set to 0deg fixed that you see the tdc mark on the flywheel.
