Phantom Grip rockers on a daily Driver?
I picked up a set of these recently:
I've been told I can't run these on a daily driver with big cams because it will tear up my VTEC rocker pads, but could I get away with it with OEM cams like CTR or ITR cams?

im havin this done within next few weeks, very few people do it but been told its "proper" way to install cams. no idea myself but any info would be greatly appreciated

This might not be related, but it is in a way.
Why not use the crane/ferrea roller system if you wanna run on the vtec lobe all the time?
I haven't tried it on a smaller motor, but the 100mm stroke H27 idles at 1100 rpm, albeit lumpy, which is cool....lol.... with multithrottles and 272 @ 0.050"valve lift roller cams.
it does turn heads......people go WTF is in that thing? lol
Seems to be reliable.
A waste of gas and emisssions in alot of ways, but no worse than a chevy with a lumpy cam....lol
less strain on the valve train.
Just voicing some thoughts and ideas

Bingo, I picked these up for $140 shipped. If I can't use them, then I'll sell them. I was actually thinking of using these on a boosted application with some stock Honda cams, but I figured this forum would have more cam/rocker knowledge. Brad's already told me not to use them with N/A cams because they will eat the VTEC rockers rather quickly, but I was wondering if they'd be okay with some stock cams. I'd love to try the Ferrea/Crane roller rocker/cam setup, but it's pretty expensive.
As I understand it, the reason to use them is to substantially reduce the valvetrain mass and to get rid of losses from the LMA's.

Re: Phantom Grip rockers on a daily Driver? (bob menuts)
ive got em in my car and it idles ok. it took quite awhile to get it idling correctly. eventually we got it. it starts harder which is what i would expect out of something running on the VTEC lobe all the time. if you have any questions about installing them just call brad. its a very simple setup. i had never done it but it didnt phase me to try. i ran the car successfully all year and only checked valve lash 1 time and it was still within specs.

Re: Phantom Grip rockers on a daily Driver? (rmcdaniels)
i only remember VTEC specs. i think both intake and exhaust are 305 degrees duration 12mm lift intake 11.5mm lift exhaust 110 degrees centerlines. DonF prolly knows exact specs, i believe those were JUNs posted specs.

That does seem to be my pattern. Or I may just say screw it all, sell these, and get that Crane/Ferrea roller rocker/cam setup. That's about two grand, but it looks better than the PG setup. I'll have to see when I get my profit-sharing bonus next month.

Re: Phantom Grip rockers on a daily Driver? (rmcdaniels)
a few Qs:
being that so much valvetrain mass is eliminated, what (rate) valvesprings are recommended? iirc, at least regarding using his cams with the stock rockers, Brad said that at he prefered the RM gen 1 outers (alone). using these PGs might allow you to run softer springs, since they no longer need to push back the heavier non-vtec rockers, although they no longer have the lmas to help.
also, if they do accelerate wear, and you want to try only using a stock cam to compensate, it might rev faster with less valvetrain mass, but there are cams which have small lobes nearly the size of stock vtec lobes, and much larger high lobes, which will likely make considerably more power (and accelerate the car better), overall.
has anyone ultimately made more power on a b series using crane/ferrea roller setup on a setup otherwise the same using the common shelf cams and valvetrain?
i think that len tried the toda vtec killer setup, which seems to be the 'proper' way of eliminating vtec, and even got it tuned to idle normally (with itbs) with P1 Jack's help. it was impressive, but i'm pretty sure that he said that it wasn't really worth it; the standard setup seemed better. of course, every engine is different, and perhaps a better grind could have been made for the same style cam... .
i can't say that for what you paid for the PG deal, that i wouldn't be tempted to try them, myself. however, the things about which i wrote above would concern me.

Re: Phantom Grip rockers on a daily Driver? (DonF)
I have crane roller cams in stock....lol
I think Don means that the regular slipper style cams we know of do not work with the crane roller setup.....am I accurate?
Why not just use regular vtec cams?
I am fully aware of the "weight" thing, but for streetuse?
for high rpm, of course, the lighter, the better.
