Thanks for sharing the results. Those are the numbers I'm after for my build and only plan to run 93-100 octane. What was the deciding factor going lower VS upper pulley? I'm not up on the different lower sizes, is 15% considered moderate? What kind of money in parts, $12k?

Nice power to the ground. I was happy with the work SpeedInc did on my 4th Gen years back. I’m curious on total price, parts and labor if willing to share.

How aggressive is your cam those are great numbers. I'm about to get my cam installed but opted out of heads since the stock ones flow so well

I went lower so i didnt have to worry about belt slippage and also i believe to go anymore than 9-10% on an upper, the snout needs to be machined to allow for a smaller pulley, and i didnt want to do that. I suppose you could say its a moderate sized lower but it would be on the higher end of moderate. Id rather not say what i have in everything, but your number is probably not far off.

Was the next run equally strong?
If not, how much effect does heat soak have on this setup?

I don’t know the answer to that, as I was not present during dynoing.
