[QUOTE=TopgunZ;4016315]You really need to display the boost graph vs the afrs. Afrs mean nothing here where psi is what we are looking for.
Yea your right,I guess you just have to take my word for it .I was trying to show that I was hitting 15 psi at 5200rpm. Thats why the graphs stop there because of the set boost cut.Meaning anyone running that psi or under will be there by 5200 vs the traditional centrifugal SC setup at 7500.
Of course hp numbers will vary depending on variables but psi should never change as its belt driven and S/C will spin at set rpm vs engine rpm.
Now writing this out , I take it back.Lol.Thinking about it a built engine with say maybe bored,4.2 will have made lower psi at same rpm as it needs more volume to fill the cylinders.
