Whats the difference?
What are the ups/downs of each?
Is one more powerful?


Thanks in advance

 

Hydraulic lifter cams require almost no attention. Solid lifters do require some maintainance, though if installed with good hardware, they are not too much trouble. Solid lifters will usually allow more RPM, so if properly spec'ed out they should build more HP.

 

Solid roller cams generally have more agressive profiles than hydraulic roller. The trade off is more noise and a bit of extra maintenece(though not much) for more power.

 

Thanks-so the solid roller is more powerful, more Rpm capable, and more maintenance.
What do you need to do to keep them maintained?
Are solid roller cams streetable?

Thanks again

 

The right solid roller can be streetable, and you need adjustable valvetrain since you have to set lash. They only need periodic adjusting/checking. If you use good parts then maybe a couple times a year. If you race a lot then you can play it safe and check every few months or after every time you race.

 

Ok thats resonable-what would you reccomend usingin a Turbo V6 build-up?

 

Try posting in a V6 related section, there are several guys on here with killer turbo 6 setups.

 

The solid cams are not as reliable but it's not the fact that they are solid that makes them that way.
It's the spring pressures related to most solid lifter cams. As 67Mustang said, they have aggressive profiles. To keep a lifter on the downside of a lobe at high rpm you need some killer valve springs.

 

I've seen some of Comp's listings, and they had a OTS solid roller for 351W that they listed as "easy on parts." You could get a solid roller with a more gentle ramp rate to save it from beating the valvetrain up.

 

I wouldn't put a solid lifter cam in a car that's mostly stock or even just mildly modified.They'll give a race engine extra power at HIGH rpm's, they won't enough good to a mildy modified engine to make them worth the trouble.

And you don't need a solid lifter cam on a turbocharged engine
