has anyone used or does anyone know how good the ferrea roller rockers and cams
perform, and also if they are of good quality?

 

I heard that you can't use VTEC if you get them.

My HX has roller rockers on the exhaust end.....stock

 

Its not that you cant use vtec, but i have hear that using cams with too radical a lift will cause them to get -stuck- on the high lobe. I think it has something to do with the pins not having enought time to disengage or something.
*only what i have heard*

 

I don't have the picture handy, but I believe by design the VTEC lobe does not interact whatsoever when using the ferrera roller rockers. I personally don't see any HUGE advantage as there are plenty 500+ hp motors out there using honda valvetrain.

 

Again, just what I've heard, but I believe they're not commonly used in Hondas because they're not all that reliable at high-rpms (7,000+).

But from the accounts I've read, they reduce valvetrain losses significantly (hence their use in the HX civics - low-revving, high fuel efficiency).

i just asked the same question to ferrea thenselves at the races in palmdale.. and they actually told me that they dont even have camshafts built for it yet so noone is running them.. but i knoe the OTDA ones are similar.. it rids the VTEC function...but is *****-tah-*** fast...a b18c ran around 11 with them...the VTEC KILLER camshafts from TODA....??>>!!
