Power expectations from a ported cammed BP4W
Hey guys, I haven't really been able to find expected HP numbers for my upcoming build.
Here's the specs;
BP-05 with a BP4W head, the head itself has had a very basic portwork, I believe it to have a slightly mild increase over stock, either way I got it for $100 and it will be way better than the BP-05 for now.
It's will getting a port match and polish on exhaust side.
Cams, I have about 275* with about 8.5-9mm lift in mind, don't really want to go digging away the lifter bosses, I'm getting a billet ground up. I'm still very undecided on duration though but I will be having adjustable cam gears.
Will have upgraded valve springs and retainers and shim under bucket lifters
Pistons I'm still yet to decide, I was thinking 9.1 for the moment as I will be bolting up the T28 I have sitting here for ages now, just need the cash first, but either way I will be beating around NA for a few months or so.
ECU is DIYPNP
intake and 4-2-1 headers
I'm looking at roughly about 150HP, does this sound about right?
