Hydrosolid Lifters

[Little-Boo]

Has anyone ever used the Jims Hydrosolid Lifters. I am trying to adjust mine and something is not right. The instructions are somewhat confusing to start with :loony: :loony: , because it says to adjust them as solid lifters. Solid lifters are easy to do just take out the slack (up & down movement) and extend the push rod so that you can barely move them with your fingers and you are done.

Then is goes on to say that if you changed out the cam and lifter blocks, (which I did) to adjust them in accordance with HD lifter Installation, which is the same way we normally adjust hydraulic lifters. I set mine at 3 complete turns 18 flats (instead of 4) and these lifters will not bleed not even after one hour:bang: :bang:. It also goes on to say that once the lifter has bled and you can barely turn the push rod that the Hyrdrosolid lifter is set. :loony:

I know I must be doing something wrong if they don't bleed, Any help would be greatly appreciated

Thanks

TDC of comp stroke?

if its not bleeding down it means your holding the valve open. loosen the rods up till zero lash should be it.

i have limiters in S&S tappets and its bottom them out, wait for any bleed down, then loosen to zero lash, then 1/2 turn looser.

Thanks Marv

Any performance diff noticed with the travel limiters? I believe we depend on oil pump up in the lifter for the valve opening. How much lift can be lost at higher RPM due to oil pressure vs valve spring pressure and cam lift

Thanks V

a real good question V!

i believe the biggest gain are when used in conjunction with steep ramp cams.

if a stock tappet has .20 plunger travel. center of travel is .10 which gives .05 of cushion either direction.

with a .10 limiter installed, plunger travel is .10 with ctr of travel .05 with .025 of cushion. (if you ctr the travel during rod adj)

at high rpm's with a steep ramp cam, the less amount of plunger travel, the tappet has a better chance of staying in contact with the lobe of the cam. resulting in correct valve timing. and more HP at high rpm.

also during a hot start up the tappet doesnt bleed down as far as a stock tappet, which again gives a more honest valve timing and better chance of start when hot.

(in my own words as i understand it)

Thanks for the reply! I don't have a big cam persey but it is the W8 .590 lift and 246 duration (if I remember correctly) I have the limiters just have not put them in as of yet. Should have done it in the Winter but have been farting around trying to get the XXX carb tuned in.

Wish there was a 3d picture of this to help my 10hp brain get fully wrapped around it...

I think for us less technically gifted ones we just need to think of it as improved valve timing / accuracy at higher rpms. I got the travel limiters too but I haven't really noticed any difference with them although I don't really hammer it too much.

Its kinda like a restricker plate on a double headed dildo. Keeps it in the middle so one chick doesn't get more than the other and feel cheated:roll:

Oops here comes probation

I am running the 650 woods cam and was told my an old school hotrod biker to use the hydrosolid lifter to avoid valve float at high rpms, which could happened with a cam like the 650. I was going to use the travel limiters, but after talking with my friend I decided on the hydrosolids. With the heads ported, 2.00 intake and 1.60 exhuast valves, decked 0.030, using 0.030 head gaskets and .010 base gaskets does not leave much room for error with a 650 lift cam. In my opinion these lifters were the best route to take. These lifters will give me about 5 more ponies at about 5500 RPMS and above. So I set my rev limiter at 6300 just in case i need it. Not that I am going there anytime soon, but it's there.

It's all about the "force in readiness" baby!
