| I've switched to solids. |

I've asked about the hyd lifter ticking I get whenever I come off a sustained high-RPM romp and determined that standard lifters have their drawbacks, anti-pumpups have their drawbacks (they don't pump up, they seem to pump down for me "at speed") and these are just the facts I gotta deal with.
There are some folk that have good luck (Edelbrock makes highly engineered systems and selected hyds for their RPM kit, so there MUST be redeeming cxharacteristics), but I've lost patience and decided that future premium builds get solid lifters.
I've considered "rollers", as they have some gnarly ramps and can make extra horsepower, but hyd rollers have beed boycotted by my mind and most solid rollers are only recommended for race motors due to the valve lash, which apparently allows the lifter to seaprate slightly from the cam lobe and thus scuff when it recontacts the lobe a few microseconds later. Preloaded hard rollers wich use external springs apparently solve this, so now I gotta decide whether the cost of the fancy-version solid roller is worth the HP boost over a flat-tappet solid gring (I don't build for max HP).
Anyhow, you're apparently dealing with the same thing I'm dealing with. I've found no fix, though I've focused on the problem during the last half-dozen builds of my different FEs.
I've tossed in the towel until someone comes onto the forum and posts an solution that offers the enlightenment necessary for me to pretend I actually understand how those little hydraulic horrors work.
Good luck,
Shoe. |
