    I like the filter 'cuz you can see what is 'happening' inside the motor. It is a good arguement however, not to run one. I also think it acts as a oil cooler to some extent

    We had a line blow off ours half track just dont know if the filter is worth the risk the nhra says you must run steel lines to oil filter on top fuel cars but they can still break

    Use custom made XRP lines and they will not blow off. If you don't have enough slack in the lines to absorb the movement and vibration then they blow off.

    Mike, do you think it is a good idea to run a filter?

    You can do what you want but , I run a system1 filter and several times I have pulled the filter off at the track and opened it up to see if something was hurt.

    It's a great tool !!!

    I use a System One filter on the scavenge side of the dry sump....between the oil pump and oil tank per the plumbing sketch that they provided....so if you have a dry sump, none of the lines are under pressure except the hard steel line that comes with the pump and runs from the pressure side of the pump to feed the engine....we look at the filter between rounds....mount it horizontally and it's easy to slide out and have a look with very little mess...

    Whoops - just re-read the first post and a wet sump filter was the topic...sorry

    We had just an Oberg screen filter on the nitrous motor and the bearings always looked like crap with embedded dirt. I would hate to say what they would look like without any filter at all. When we built the blower motor I switched to the high flow System 1 filter and what a difference. The bearings never have any dirt embedded in them and the System 1 is so easy to pull out and check to see if anything is starting to go. The Oberg was a big pain. So the anwer to your question is yes I highly recommend a System 1 filter but make sure it is the high flow unit. If nothing else just checking it for bits of metal is great between rounds or at the end of the race day. The lower bearings on a blower motor hardly ever need changing if you use a filter. Without a filter you would have to change them on a regular basis so that yhelps offset the cost of the System 1. The other thing is the needle bearing in the roller lifters withithout a filter they are going to get crap in them and fail. If you run the lifters with the speacial little oil hole to feed oil to the needle bearing it will block up without a filter.

    We pull the filter every time the Top Fuel car is started. System One is the best!

    You definitely DO NOT want to loop the filter line.

    System 1`s filter is killer. As stated above, its an excellent tuning tool for you at the track. If you have some extra, questionable material, its easy to see it in the filter and go from there. I`d never run a car without a filter, personally

    What about this? Can i put a in line filter between the pan and the inlet on the pump and loop the outlet? I have system one filter off a dry sump and thats how we did it on the dry sump anyone see any problem with this?

    Personally I wouldn't put a restriction on the suction side of the pump in a wet sump engine. I have plumbed scavenge screens on the scavenge side of a dry sump engine... but remember, in a dry sump system you have multiple scavenge stages of the pump and lines that feed your oil tank which in turn gravity feeds your oil pump.
    Ask your self this - What kind of damage do you think is going to happen if you do tear up something and plug the filter, starve the oil pump and the entire engine of oil ?

    I sell the System 1s and have had a number of people ruin the screens by using too heavy of oil. If you use the "regular" screen(45 micron) dont use heavy oil. Use the HD screen (70 micron) for anything over 50wt.

    I have always used system 1 filters on any race engine built or tuned for customers. over the past season in our Alky car we have hurt a couple of motors, mainly due to being grredy and running the motor on kill. We have a dry sump pluegar pump, on a billet hemi. We have run the canister filter on the suction side of the pump, motor stays clean and shows up a bit of what the motor is doing, but taking the pan of really is the key. So my question is when you bang the motor, the oil is contaminated through out the whole oiling system. what we plan to do is use the davenport oil pump bypass pipe and run a inline high flow filter on the suction/scavenging side of the system after the oil pump but before the dry sump tank to contain any future mess. not that i am planning anymore broken rods and melted pistons:eek:

    Is that what people do? is there any negative issues with this set up

    Thanks Clarky
