I forgot the range maybe 40 degrees I’ve since given up on making it work. Gains are all under 4k pretty much. My needs in racing never sees rpm that low. Im deleting vvt and doing adjustable gears now.
@samdemond1 im using a 4.24 it’s working well so far. Biggest issue is the stock-ish trans right now, doesn’t like the rpm it turns. Been fighting being locked out of gears
So with porting and raising the compression is there thought to volume matching across the cylinders? Or is that something that is addressed in tuning or just doesn't matter?
I based it off an r32 head i had at work. Pretty much the same besides the 3.6 having 3 injectors pass through 3 rear cylinders Im trying to get to a point where i can have it flowed compared to a stock one (probably when im able to add higher comp pistons) Im trying to save up to build an exhaust manifold where i can have 6 egts as well That would give me all the data i need. But the costs associated with that is not something i can get to anytime soon.
