Thanks for any info.

Be more specific with "tangential pounds of force"... LOW tension can mean a lot of different "force pressures" less than the normal.

I'm guessing that by your further actions here, you are unable to be more specific.

Sorry bout the mlss leading topic. I had to look up some forces i dont have a clue what they do. Hell and i still dont know. I have. 043 .043 3/16 low tension oil rings and was just wanting some info about using the basic evac kit with them and the electric pump and the evac pump. How much vac is needed?

dfree383 April 11th 2014, 4:48 pm

What oiling system? Pump? What you using it for? You have it already set up for vac? Coatings?

tconnection April 11th 2014, 5:59 pm

Its all drag, reg hv oil pump, i have the evac kit hooked up. No coating on pistons but they are gas ported.
Thanks

Regular "of the shelf" LOW tension rings vary in tension. Thinner rings have less tension; a 3/16" "off the shelf" LOW tension oil ring will have about 16 pounds.

You chouldn't have any problem with those Speed=Pro type LOW TENSION rings even with NO vacu-pan system.
The ULTRA low tension will probably be helped considerably with some kind of crankcase evacuation system.

Most racing engine builders use a fish scale "PULL method" to figure oil ring tension for correlating different "Tangential tension". THAT will have a lot of variables as bore finish, lubricant type and rail radial thickness will cause different readings so they always use the same bore finish and lubricant for their testing.

Basic answer the crank case evac system will get you a few hp on you engine. It will also help later as the engine wears.

A vac pump pulling about 10 lbs is about the limit (it's safe) with a regular wet sump system but it's not cheap for the system. But you will gain additional power over the evac system.

Bingo! Basic answer, thanks. And I didn't know speed pro made rings for total seal.

I must have missed it ... I didn't realize that Total Seal was even mentioned anywhere in this thread.
YES ... Total Seal buys a lot of their bulk rings from all different piston ring manufacturers.
