Going to a 'solid lifter' supports the ability to have a more aggresive 'custom' camshaft and more aggresive valve spring pressures.

The question to keep in mind is: Is this overboard for my setup? And Am I willing to adjust them after "X" amount of time using them? After all they are solid, and will need some adjustment.

Not something we would recomend for a daily driver, I am sure it can be done, its just trying to considering if its worth it.

We all know that the Hyrdaulic Lifter isn't optimum for Very High Horsepower Dedicated Drag setups. I know guys can make good horsepower with the Hydraulic, especially if they learn to control the system to there advantage.
I don't really see you have an issue with the Hydraulic Lifters as per say, but maybe try DCR, he does make the Oil Modifier and I thought he had upgraded lifters as well.

 

Yea, i do have the oil modifier in my car now. Im building the car, but yes, it will still be my daily driver. With the BLE solid lifters, they claim that i wouldnt have to adjust them after the initial install and adjustment. My setup will be a p&p head, Si 1mm+ valves, bc springs and retainers, bc stage 3 cams, dcr oil mod, a built low compression block, and a big turbo with high boost numbers. I do plan on reving the motor to about 7500rpms, but my concern is "will my lifters collapse at that rpm range with my bc springs"? From what i hear about the solid lifters, they arent good for a daily driver. It seems that my choices will be a daily driver thats not at its full potential, or a track only car :jester: Im curious, if DCR were to chime in, what is done to the "custom" hydraulic lifters? I saw them on the site, but i cant find much info on them. Thanks for your help too :thumbsup:

 

After modifying each lifter we make only few dollars profit. As far as solids...been there and proved that they are a disaster for this application. 1st the cam grinds available are not ground to tolerate running valve lash. 2nd the valve lash destroys the rockers tips from the hammering effect of the lash gap. The OE rockers are not built for lash and fail in time from the effect. We have safely taken our valve train consisting of the DCR oil modifier, DCR lifters, DCR springs and retainers to 11,500 rpm.

 

Ok thats what i wanted to hear. Thanks for the input :thumbsup: BTW, i wasnt trying to bash you, saying that you sold stock lifters. I just wanted to get some info on them since i havent heard much input on changing lifters

 

uhh from their website.

 

The mid ground you are looking for when using big cams/hp but dont want/shouldnt use solid lifters is

Rhodes Lifters, they make them for the SRT and they were dynod on a crane 22 cammed 1gen neon. Top end lost like 5 hp (on a 200+ hp car) however mid/low end pickeed up a ton of power.

Research them, its like have a Variable Valve Train to a certain extent.

 

The reason for the failure is simple. You are not lashing them right!! Any time that you are going to use a set of solid lifters with a hydraulic cam you will need to adjust the lash accordingly. Generally on this I would run .025 to make the setup work. There is power to be had and I can prove it. Drag only, would I even change to a fully solid system, but if done properly you will see gains with the solid lifters. Oh, and just because I said this.....please dont even mess around unless you know what you are doing.

 

.025, that must sound like a tin can full of bolts rolling down a hill.

 

It's actually quieter than the stock valve train Ive been running them in my car for 3 years never had a problem.Ive got over 100 passes at the track also,the thing I noticed the most was the low end pickup improved majorly over the stock valvetrain.As far as lash I set mine at .002 and never have had a problem,this is an automatic car with a 4000 converter,standalone etc. 2.0 cams.

 

rofl x2. 11.5k rpm. i'd love to see a dyno vid...

 

.002 > .025
