I have trick flow top end package. Stock block With Si trim. I installed It but it has 8’ crank and 3.5” blower. Just wondering at 6k how much boost do you think I’ll make?

I know this is an older post but to update this thread. I still run the 8" Renegade pulley and a 3.33 upper. I made 13-13.5# of boost at 6k. Hope this might help someone down the road or doing a search anytime in the future

So helpful! Thx for the update.
