With the EJ's I have been inside the main saddles almost always show some microwelding... Putting a program together that makes boost down low isn't much different than turning on your nitrous at 2k...
if that 5.4 DOHC Ford motor made the same power per cylinder as one of our EJ25's i can gaurentee that things are not going to look 100% . imagine a street drivin 5.4 that makes 200horsepower per cylinder . thats 1600hp. point being , I dont think thats exactly apples to apples .
Concerning the increased load levels down low however would pose a problem you wouild think . well i ran the car compounded for like a year at least. on a stock motor . with 437whp. with 15psi on the supercharger .and when we took the motor apart the bearings were perfect . Along with the acl race bearings , we have a modified oil pump , and the oiling setup on the crank is now a t-oiling setup . i think we will be fine at 18-20 psi. but at the end of the day its up to the tuner , so it may stay at 15 for all i know but i doubt it . hope that helps .
