Today was the day. I drove my CA18DET S14 for the first time in over 4 years today. It put such a huge smile on my face. The EFR7064 did not disappoint. I was really worried about the bottom end of the rev range being terrible. 4 port head, CPC manifold, HKS 264 cams and a 70mm turbo is NOT the combo you put together and expect low end torque. The most common thing I read about the EFR was how it made the engine behave off boost. Trying to explain this in words on the internet, or a dyno plot, or even a video doesn't really do it justice. I don't know how or why, but I have torque down low. Not mind-blowing, V8 like torque, but like stock turbo at 7psi kinda torque. I have a lot of tuning to do. The tune on there is from the T04E and stock intake manifold. So, what everyone wants to know, when did it spool. Well, it was hard to tell for sure, as I kept hitting boost cut, and my boost gauge must have a bad connection somewhere because it kept acting up, but I'm pretty sure I was hitting wastegate pressure of 7psi by 4K RPM!!!! And the really amazing thing was I was making positive boost by 3K. But the top end. I couldn't believe it. I kept hitting boost cut and it took me a little while to figure it out. I had boost cut set for 8psi, but I was maxing out the wastegate and by 6500 it was creeping up to 8psi. Then I bumped the boost cut up to 15psi. I about lost my mind. At about 7500 I hit boost cut again. I actually said, "Oh Fvk!" out loud. My butt dyno says well over 300whp at 15psi at 7500, and there was no signs that power was falling off. This thing is going to be a beast. I can't wait to get all the bugs worked out and get it on the dyno and get a good tune on it. This turbo is supposed to be capable of 560hp. I was hoping to get close to 500whp, but I didn't think I'd actually get there. Today changed my mind.
I know everyone is going to want pics and vids, but I discovered a fuel leak in the return line, so until I get that fixed, I'm not even going to start it again. As soon as that's done it's going straight to the exhaust shop. It's WAY to loud for my quiet little neighborhood.
