The most E content I was able to run on a C7Z that had ported blower, 2.3 pulley, 95mm tb, headers, LPE hpfp, and JMS low side was E60.
Same C7Z did Heads/Cam 32% lobe, Maggie 2300, +30 injectors, and the low side would just squeak by on E60 with 14.5psi...high side was solid.
Now the C7Z has Maggie 2650 and Cordes low side. Boost is @ 16psi and we are getting ready to start data logging. I will be updating thread in the FI section once I get some data.

Gotcha. Makes sense. If I go any further with power a 2650/cam would be next to try and get into the 800+whp range. No E at that point though, just 93.
