Guest Removed Posted April 21, 2010 Report Share Posted April 21, 2010 just use a fine file ,and take your time Quote Link to comment Share on other sites More sharing options...
10_penn Posted April 21, 2010 Author Report Share Posted April 21, 2010 guess i could do that... first time i've gapped a set of rings before. last time i rebuilt an lsj we went with stock rings which are already set to the gap thanks GH Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted April 21, 2010 Report Share Posted April 21, 2010 just take your time... measure twice, and be sure to set them correctly. i see alot of people over do it with the ring filer, and you cant add to rings Quote Link to comment Share on other sites More sharing options...
10_penn Posted April 21, 2010 Author Report Share Posted April 21, 2010 this is true ^ my rings will be arriving this coming monday. Total Seal - comes with its own set of instructions for setting ring gap, but what would you recommend? motor will have the following : 2.0 block stock sleeves with 59K miles diamond pistons, stock compression/bore ported head, stock cams, stock valvesprings TVS 1320 supercharger to replace the stock supercharger (1.32 L vs 1.0 L) other bolt-ons Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted April 21, 2010 Report Share Posted April 21, 2010 normally, the instructions tell you where tgo set them depending on boost... id say follow them for the super charged app. and you should be good. i always give the top a little more then the 2nd, it takes more ot the heat, and has to expand more. and make sure you space them correctly aswell Quote Link to comment Share on other sites More sharing options...
10_penn Posted April 21, 2010 Author Report Share Posted April 21, 2010 do you think how much boost has any affect? like stock boost is 12psi on the m62, on the TVS i was seeing 21-22, although with the ported head it would go down a little bit Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted April 21, 2010 Report Share Posted April 21, 2010 just read what they put into the instructions... its should cover it... but i would say open a tad father then stock. Quote Link to comment Share on other sites More sharing options...

koolrayz Posted April 21, 2010 Report Share Posted April 21, 2010 http://www.summitracing.com/parts/SUM-CSUM2505/ This is the filer I have. You need the ring squareing tool to measure properly. Good luck filing the ends square by hand lol Quote Link to comment Share on other sites More sharing options...
nurkvinny Posted April 21, 2010 Report Share Posted April 21, 2010 I would also use the correct tool, which I have somewhere. Let me dig through the garage tomorrow night. Quote Link to comment Share on other sites More sharing options...

Guest 614Streets Posted April 22, 2010 Report Share Posted April 22, 2010 Best to use the filer that runs them through square and only file in one direction. You can come to my shop and use mine for $10. You can't leave with it but do it here. Top Ring Moderate Performance (.004 per inch of bore diameter) Drag Racing, Oval Track (.0045 per inch of bore diameter) Nitrous Oxide - Street (.005 per inch of bore diameter) Nitrous Oxide - Drag (.007 per inch of bore diameter) Supercharged (.006 per inch of bore diameter) 2nd ring gap Moderate Performance (.005 per inch of bore diameter) Drag Racing, Oval Track (.0055 per inch of bore diameter) Nitrous Oxide - Street (.006 per inch of bore diameter) Nitrous Oxide - Drag (.007 per inch of bore diameter) Supercharged (.006 per inch of bore diameter) You want to go even or bigger with the 2nd ring gap , it relives the ring inter pressure , which is the pressure built up between the top and second ring on the compression stroke. The air that makes it past the top ring gap fills the void between the two rings and takes the top rin and pushes up on it. You dont want that for power and cylinder sealing. Bigger gap or even on the second ring allows the air to scavenge out of that space. They figured that out years ago in NASCAR and its how I set mine up.

Guest 614Streets Posted April 22, 2010 Report Share Posted April 22, 2010 What is that bore size on that motor? Quote Link to comment Share on other sites More sharing options...
Guest 614Streets Posted April 22, 2010 Report Share Posted April 22, 2010 3.38 in std bore correct? If STD go .006 x 3.38 = ring gap .02 both rings. Quote Link to comment Share on other sites More sharing options...
10_penn Posted April 22, 2010 Author Report Share Posted April 22, 2010 it's an 86 mm bore x 86 mm stroke "square engine" so, you are correct, 86mm = 3.3858 inches you are saying .02, as in 20 thousandths? Quote Link to comment Share on other sites More sharing options...
Guest 614Streets Posted April 22, 2010 Report Share Posted April 22, 2010 yeah but im wrong you need the block to read the rings..... so u need the tool at ur place. my bad brain fart Quote Link to comment Share on other sites More sharing options...
10_penn Posted April 22, 2010 Author Report Share Posted April 22, 2010 yeah thats what i was thinking. you'd need to take the ring and set it in the cylinder, to make sure the end gap is ok. unless you happen to have a 86mm sleeve? lol Quote Link to comment Share on other sites More sharing options...
