All,
I've dynoed my big bore combo before, but i finally decided to try a BBK 65mm throttle body. I ported the lid in an attempt to match the dual butterfly's, but I was reluctant to get too agressive due to the IAC path.
I dynoed on 8/16. It was 83 degrees at alternative auto (inside the shop)
Last time i dynoed there, it was 71 degrees. Lidio said that if I would have waited until the same conditions (regardless of using SAE), I would have seen an additional 5-10rwhp. In my experience, Lidio is usually correct.
In short, I made 378rwhp & 366.5 rwtq. I was pretty happy. I'm guessing that if i redyno in cooler weather, i'll see around 380-385rwhp! I'm pretty happy with the numbers. But the TQ curve & peak is what really impresses me... I took the time to make alot of comparisons between pre-big bore & afterwards. I hope you all find this info interesting. If you have any questions, let me know...

Here is the before/after adding the BBK 65mm TB: 305 vs 305 + BBK
