I have heard a lot of good about both the Crane Roller Rocker set up and the Web Camshafts Entended Rocker Pads. Im trying to decide which route to go for my NA H series drag motor.

The Web exteneded rocker pads will allow for cams beyond the standard limit of .505 when using the stock rockers. I have heard of people running cams with as much as 13.8mm of lift with the Web set up.

The Crane roller rocker set up seems to be the more efficient of the 2 choices which would seem to be the better option for overall power but you are still limited to .505 lift. The lift limitation makes the Web set up look slightly better.

I dont know, Im confused. What is the best option for maximum power and performance?

Added HP, Torque and RPM of Roller Cams & Followers for Acura-Honda VTEC DOHC 4-Cylinder Race Engines!
• Designed in conjunction with Crane Cams’ cam profile engineering group for use with the latest Crane 8620 steel billet roller camshafts.
• Fully CAD-CAM computer engineered to minimize “moment-of-inertia”,
deflection, and to maximize strength and reliability!
• Dyno tested and proven to 10,000+ RPM.
• 52% lighter than stock steel followers for increased RPM, quicker engine response and acceleration.
• Precision roller needle bearings eliminates follower “skid” on cam lobe surface.
• Greatly reduces operating friction, adds HP and RPM.
• Easy, bolt-on installation! No cylinder head modifications required.
• Comes complete with all required hardware and fasteners.
• NOTE: Will not work on stock cams due to enhanced geometry.</TD></TR></TABLE>


They will be used in a NA drag car.

Thanks

 

Great question

Im curious as well

 

Very innovative stuff.

 

what about the phantom grip rockers?

heres a thread discussing them

You are still limited to .505 lift with those.

 

would somethin like this REALLY make a differance in a NA car?

Good luck getting this stuff for an H-series engine.

 

b19coupe. What do u think? this worth it? make a differance?

Both are already available for the H series

 

Wow! Color me surprised. Good luck whichever route you choose.

 

hmm the web stuff looks like 1 piece? it says hardwelded? are they modifed stockers or something new all together? also on the PG ones, it says they use factory Honda rocker pads. how is it secured to the al.?! anypix with the pad installed?

As far as I know, the Web rocker arms are not modified stock units. They are new Chromoly rocker arms.

As for the PG al. rockers, they still use the stock VTEC rocker which has limitations in terms of how much lift you can run. I have no interest in running the PG rockers. This thread was in reference to the Crane roller set up and the Web extended rocker pads, not the PG set up.

No offense, Im just trying to get some specific info. I can see advantages in both so Im not sure which route to go. Maybe some feedback from emmbers who have used one or the other can help me make a final decision.

Thanks

 

well the PG setup does have advantages; since it runs stock pads you can use whatever exisiting cams you have, and still drop significant mass.

the roller rockers setups with cams i've heard mix things about them. but hardly ever, from any actual users... they've been out for at least 2 years but i've never seen any dyno results of the torque curve they make, or the power they put down. if anyone has dynos to share please do so.

is there any info on the weight of the the web extended rocker arm setup?

 

Ive been really looking into this the last few days. I see advantages with both options. I am starting to lean towards the Crane Roller set up though. You can run some pretty serious lift with the roller rocker set up which was the main advantage I saw in the Web extended rocker pads. Crane has custom options with advertised lift as high as 13.6/.520 which was the area I wanted to be in. My head flows extremely well in the .500-.550 range. The added bonus for the Crane roller set up would be the fact that its a much more efficient and friction free operation.

The company I work for has delt with both companies for several years so pricing isnt too bad either way. The $ isnt a factor in my decision.

I would still like to hear some feedback from some of the guys running the Web rocker arms though before I make a final decision. I can think of 2 pro all motor individuals who have posted on this board over the years that run the Web set up. Not to sure if either of them would be willing to discuss their experiences or even admit that they are running them though.

 

i dont see the lift limitation w/the PG rockers... you dont need the LMA with those anymore and you can grind down the bottom side of the rocker to get more clearance.

as for the crane/ferrea stuff.. i have hear of more failures than successes with those.. then again, w/the internet you rarely hear when something works well, but always hear when it dosnt. i dont like the fact that there is only one cam supplier for the web and ferrea rockers

 

There are quite a few racers that swear by the Ferrea/Crane setup, however, most of them won't admit to running it. The only one I can think of right off hand that actually advertised it was Gardella.

 

I would like to take some time to address some of the comments / questions that have come up about our new rocker arms. They are new rockers, and not reworked OE rockers. The will handle over .550 inches of lift. Our rocker set up is approx 100 grams lighter then the OE rocker setup, not to mention the additional weight loss in the cams. We have been developing the rockers for more then 2 years now, and have done a lot of track and dyno testing. We hope to have some dyno charts for you in the near future.

I think a lot of you are missing the point about springs and spring pressure running aginst the cam lobes. With the other 2 setups, you still have 2 springs pushing on one lobe. Depending on your springs and set up, each spring has about 195lbs nose pressure, times 2 = 290lbs. Too much pressure and you know what will happen, worn parts, and or broken parts.

If you have any question I can help with please let me know.

 

whats the cost on those things and i am going to assume web is the only company that makes a cam for those things?

 

The set retails for $1525 (16 Rockers and spacers) I can not speak for what other companies make, but yes we do have grinds for them. You would need to call and talk with someone here so they can get all the details of what you have going on in your motor, and make a recommendation for your application.

You can download our current catalog from our web site to see other offerings we have.

Crane/Ferrea RR's all the way. Go here and look who's running them from DPR http://www.dprracing.com/Media...s.htm

Add in everyone else that just keeps it a secret and its a no brainer.
