Thread: Questions on the Double Roller ....

When modding, high rate springs will cause issues with stock chain too as the tensioner will wear as well... Just sayin! Lolz

^^^^^^ please reread blueguys post about overkill and tep running singles on cams that are bigger than an s1x for example. its a question of which will fail first single and high spring rates or double???? personally the less headache to deal with the better so single it is and like before im pretty sure id break something else before a timing chain anyways like a 4t6fail transmission for example! lol

Actually I have, read my post, they advocate not needing the higher spring rate for some cams, which I agree, lol... But the fact is when you DO use the higher rate springs, based in insane lift, if stock, you'll need to change your tensioner more often.

Of course this should be expected, I just thought to mention it, not debate it...

And of course, when modding, changing the CAM, adding MORE power, if care and consideration is not given to all aspects of your upgrades, something will break, lol. Best I love is, how people wanna get to 400whp, and never think about upgrading their brakes! Hahaha

LOL i can say for sure shutting down at 130 mph with the 330whp s1x e85 setup is sketchy enough lol!!

im running 105s and s1x no problems currently


and curious though , who else broke a DR?

Dave ran manley 130's.

Reptile was running LS6's.

Pretty sure Will was running LS6's too.

150's are silly.

I ran 130's with a double roller and my thrasher cam, and it was pretty rough compared to an XPZ.

Y'all broke a DR for real? That's crazy

Reptile did.

I did.

I know there have been others too.
