No need for the personal attacks, they are only my educated and tested views as I stated. I have never even seen an EFR, like most of the other guys on here. I welcome the debate, and happy you have set us straight on the shaft construction to some extent. Glad you edited your post anyway.
It doesn't change the fact your view is only that, everyone is allowed to have their own opinion. If it conflicts with your ideas or testing, it doesn't mean it's proven wrong, and doesn't give you an excuse to call me ignorant. There are after all many ways to extract more airflow, or gain response. I have seen some great results from a myriad of turbo setups, and even the use of exhaust pulse energy seems much less important to me than manifold velocity. In your opinion, how would a rear mount turbo setup work at all?
That aside Geoff, I just noticed your wastegate runners exit the manifold on a 90 degree or worse. You should trial facing them in the direction of gas flow to allow better breathing in the top end. They aren't just bleeding manifold pressure after all...
Are my ideas out of the box? Yes, but I have proven them to work many times. Your choice if you chose to ignore me, I won't be losing sleep over it.
Back to EFR discussion please, lets keep the split pulse discussion for the other dedicated thread.
