What is the the average lifespan of a solid roller lifter?

 

anybody know??

 

Talk to the guys from Futral Motorsports

 

Idling time is hard on solid lifters. With the spring pressure required to run solid roller lobes the lifter's needle bearings get hammered during long idling. New pressure fed lifters that have come out in the last few years have improved the reliability of these. What you may want to think about is the HLT's by Morel. They are a hyd roller but you can run solid roller pressure on them to go up in the rpm range.

awsome, thanks.

 

Depends on how agressive your cam is and how much spring pressure you have. Even then, it's kind of a 'maintenance' item that needs to be replaced whether it looks good or not.

 

I have been seeing ~10-20,000 miles on my solid roller setups (LT1/4). I do recommend that you pay the extra money up front and buy a real good lifter. Nothing like having a $12k engine break a lifter....ask me how I know Not a good time.

Also, listen only to the guys that have actually built a solid roller motor for advise and have one of them spec out your setup if you go this route. Matching these parts is an absolute MUST if you want a reliable valvetrain. There is WAY less room for mismatched parts with a SR than a hydraulic setup.

As mentioned already, idling for too long should be avoided. The lifters need oil....that is the only way they will survive. I try to not let my motor's idle for more than a minute. If a situation arises where I am going to be sitting for longer than that, I just bring the idle up to 2000rpms or so for a couple seconds just to get a little more oil pressure built up, then back to idle.

Hope this helps

Thanks for the info in this thread - I always wondered why solid rollers weren't more prevalent on the streets since they have such great power potential.

 

I love solid's.....I prefer them over hydraulics for all of my builds. However, you just need to have the right parts. Alot of horror stories out there because of mismatched parts or lack of confidence in setting/checking valve lash.

The power cant be beat though!

 

How much more spring do you normally have to run to compensate for the heavyer solid's?

 

what exactly do you mean by "heavier solids" ??

 

So what do you do about warming up the motor on a cold start? My motor let go and ive been playing around with the idea of a SR set up. Just like to know some more about em before I make a final decision.
