Yeah, this one should spool faster with the .68 AR as well. I don't really need this big or bigger because all I wanted to do was approach 500 rwhp. Judging from the 6267's little dyno burst to 380 rwhp at 8 psi.. I don't think Im going to have any trouble reaching that at all. Ideally, I want to set up for 10 psi (ext. wastegate spring, no boost controller), 14 psi (normal) and 18 psi (scramble). 18 psi would be a rarity I think, but the turbo could go much higher. My build is based on longevity and performance, so I want to keep the boost low. Its crazy how well the engine runs with the VPro though... and the way Reg (my tuner) is setting it up is very innovative. I would have never thought of the things he is doing with the engine.
Just looking at the AFR's and how well mannered the engine is, I am thinking 32 mpg on the highway will be pretty easy to achieve. And that's with no cams, no porting, just a stock 7M with forged pistons.
I wasn't aware of how the ID injectors click though, that caught me by surprise. I thought it was a sticky valve when I heard it and almost panicked. Every cycle.. "click"... lol.
