Im not saying anything, cause JETPILOT said i dont know what im talking about and there isnt any shaft difference in the helix but i guess its a optical illusion?
I agree Bponci cranked up 12mm pumps will snap cast cams too..
The wider lobe is not needed with the Helix 2 grind.
Longer duration allows a slower lift on the lobe compared to stock. The wider lobe also slows tappet rotation which adds to higher wear on regrind cams. Rotating the tappets ( called sliding tappets also ) are key to slower wear.
The Helix is harder at the lobe as well. The lighter overall rotating mass/weight helps avoid breakage under heavy loads. Simply less mass.
When the molds are produced, we can make them any configuration we like. Wider, not as wide, etc. A larger diameter, etc. The Helix is made this way by design.
The only load we dont like on the Helix cast cams is a 13mm inline P pump. Actually it is not the load to turn the P pump, but the unloading and shock that can oocur if a driveline piece breaks and the load is removed quickly.
The Helix lobes are the same width as the 12V cam, but not as wide as the 24 and CR. Some discussion has occured on paying for another mold, but this has not been needed. Our wear rates are the lowest we have seen on any of the cams available.
Availability?

It will work both ways. Some Billets will be able to "drop-in" and others will require machine work to the block to install cam bushings compatable with 8620 steel.
Pricing will be higher for the "drop-in" part.
In some cases, the drop-in will be less money for a guy who's build requires a Billet cam and will not want to tear the engine down, machine the block and re-assemble the whole mess. If you are already going to rip an engine apart for a rebuild, etc. the bushing route may save some money.
The F1 Billet Helix is also has a thicker shaft area between journal number 1 and number 2 for increassed strength. This is different from other Billet cams available now that have a reduced diameter and resulting lower strength.
Generous radiusing of the steel where the main shaft meets the bearing journals also adds durability. We have the most material you can have in this area without risking tappet interferance on the wider CR tappet.
Have you ever even installed an aftermarket camshaft? I am guessing with your unlimited knowledge that you have not.
Probably does 3 installs daily. Hes a "doer not a talker":hehe:
a thousand B series aftermarket cam installs a year?!?! I can't imagine the total number of aftermarket cams sold/installed each year amounts to much more than that (IF that!)
