1.6 rr

What would be the difference in hp from using 1.6 roller rockers or the stock ones, my car dyno at 365 rwhp with 1.6 rr if i remove them how much do you think my rwhp will drop

First of all...what is your reasoning for doing so?

Going back to stock rockers will decrease your cam lift from .544/.576 to .510/.540. You will also lose a few degrees of intake and exhaust duration. Not to mention add weight to your valve train.

Not sure what that would translate into, if I had to throw out a number, maybe 10-15rwhp????
