I lost .6 going from the 6.0 to the 408. I'm sure there are many variables. I lowered the compression. I didn't change the pulley, so I lost between 2 and 3lbs of boost, and my tune probably needs more work. Plus it was pretty hot today. Last year I was seeing 115 mph, today I saw 112 mph.
At least I didn't break anything LOL.
What do you think?

Thanks,

What compression is the new motor and what boost do you see now?

How much timing are you running?

Compression is supposed to be between 9:1-9.5:1. Stock was at 10.1:1. I'm not sure where it ended up. The heads have the stock combustion chamber and I used stock thickness gaskets. The pistons are -20cc.

Embarrassing to say, I don't know how to answer that. I know where the timing tables are but, how do you put a number the that? Is it an average? I feel pretty dumb as I'm typing this LOL.


Of course, I was thinking about this all day yesterday. In addition to this I think I need a new in-tank fuel pump. I do run an in-line. <<<<just another addition to my brain storming.

Thanks
At 100% TPS and 6000+ Rpm I see between 10* and 14*.

I am seeing some KR. It was different on each run.
