A CNC company I know is working on these. Pricing will be "attractive."

Version 3: Lightwieght Race - Locked Roller

Mmmmm!!!! i like what i see. are these gonna be pretty much oem spec stuff,material,harness,etc... can you use the roller rockers on regular cams[skunk,rm,toda]?

Rocket

1. Rocker Pads will be hard milled material that will be compatible for sliding contact with camshafts.

2. Roller rocker is to be used with roller profile.

will they be lighter?

I'll be rockin the roller vtec for sure

wow I want pair of these if it frees up some power and is reasonably priced. The roller vtec sound nice. Would that remove our loud vtec pop though.

Will I have to run an extra oil line to the head? Or can I just use high quality oil?

Hey that crack in the block thread got 60+ responses

Didnt Crane or someone make VTEC roller rockers???

Rocket

1. Yes, lighter. CNC aluminum bodies with hard milled pads and/or rollers.

2. Loud VTEC pop with roller profile, depends. Specify weak *** stock like primaries and VTAK will be vicious.

3. WUT CAMZ TO RUN? U KNO DA WON DAT HITZ HELLA-TITE MAD-VTAK YO. DAYUM!!!!

4. "HOW DU I FIX DA CRACK IN MY BACK?" YA DON'T, YA HURD.

lol.

any h-series love?

Zaraki

What are the advantages of using these rocker arms?

Rocket

Maybe some limited runs for H22A.

lude98SH

i vote for some h22 love.

These will use the stock rocker ratio correct ?
Also the locked rocker would be similar to "vtec killer cams", like the toda and crane units, correct ?
Who makes roller cams for hondas besides those select few and most of those from what I remember dont have primarys so they would need to be used on the locked rocker unit.

What kind of gains are you predicting with the roller rocker ?

Rocket

Ratio is about the same. Ratio is 97% determined by Honda already - location of cam and location of rocker shaft.

EatSleepJDM

1st version can be used with skunk2 and the like cams correct? when are these expected to hit the market, any idea?

bluedlude

sign me up for a limited set and some h22X cams. cash in account.... also are you going to get some new profiles ground for the roller sets?

what are those made in? solidworks?

d15Beta

good stuff!

any chance for a sohc? HAHAHAHA

Fink29

whats up rocket? Will you be producing cams to use with version 2?

SMSP

You need a 4th version. VTEC killers with individual rollers. Your version 3 still has the (2) rockers plus (1) roller, so make (2) roller rockers and (1) spacer. Total mass should be near the same plus each roller will have less load on it. therefore extended life will be had by all.

what the point of rollers without some steep ramps

stealth50k

So we need new cams for the version 2 roller vtec or can we use our regular camshafts like toda and skunk2 with them?

Just want to be sure since i haven't seen any of those camshafts yet with rockers and a roller in the middle yet

With the race locked roller, how much can you play around with the springs compared to what is available on the shelf?

prettylew

so in order to run the version 2, you would need a custom cam with a roller vtec profile?

im in for version 1 then, i like my cams and im a cheap *** lol

Rocket

1. It's hard to fit rollers on the outboard rockers. The BVTEC head is not designed with rockers in mind. The K20 is, and that's why the K20 rocker ratio winds up to be 1.75. It's all in fitting the package together.

2. Yes, hybrid traditional/roller vtec cam would need to be ground for Version 2 Rocker.

3. The CAD program is Solid Edge (not Solidworks). It's a very very good CAD with full life cycle (design, development, motion assembly, enhancement tracking, etc).
