| Light tension rings in a 632 | Login/Join |
DRR Sportsman |
How many of you 632 & up guys run light tension springs, I'm rebuilding my 632 now and I have both light & std. tension rings, I would like to take full advantage of my 5 stage dry sump & 4 vane enhanced vac. pump & gas ported slugs but am worried if it'll 'Huff' alittle....my machinist/advisor don't like using light tension rings on big bore pistons. Thanks!  | ||

This is diceman1530 's old motor built by PAR w/ light tension rings. Hoping for 1100 hp. ...that's 1 vote for light by Howie... | |||

Agreed but my engine is 17 cubic inches shy of the club. | |||

What size is the oil ring,, 3 mm standard tension rings are pretty light to start with vs 3/16"This message has been edited. Last edited by: TOP38, | |||

Yup, 3 mm. The low tension set is 11-12#'s, can't find info on set that is on pistons now - he told me they were 14#'s....JG7708-4600-5 Ain't a whole lot of difference there so I'll throw them in as-is w/ 14's... | |||

I would stick with 14#. It will probably be 8 when its running. The aluminum block grows. The bore isn't exact because its been honed a second or third time. | |||

I didn't see anyone ask , will this engine see any nitrous ??? | |||

Machinist of mine doesn't want me running them, so never have. At 555ci. It's is not worth the little bit of power and since I bracket race... Always come back to probably not worth it.  Configuration: 3350#, 582 C.I., 60 - 1.24 1/8 - 5.53@ 126MPH 1/4 - 8.73@ 159MPH  3700#+210lb driver, FULL interior, through mufflers, 10.5 tire. 60'-1.333 (IN 4000ft DA! Joisy Math excluded; 1.25sec using JOISY MATH.)  1/4 - 9.60@144MPH | |||

Don't do the light rings. You will make more HP with an oil free cylinder than you will by reduced drag on the oil ring. | |||

I wouldn't run anything but those. If the hone is right it won't smoke, especially with lots of vacuum. Abbott Racing Heads (432) 558-2841 | |||

This ^^^^^^ Not worth taking the chance of oil contaminating your combustion chamber, it's a quick path to detonation. "Despite the high cost of living, it remains popular." Dave Cook N375 | |||

Thanks all, I went w/ the 14# rings - I already had a detonation failure once upon a time, don't want that again...Motors going in 2-nite! | |||
