turbowrenchhead Posted May 19, 2014 Author Report Share Posted May 19, 2014 I don't want to use an impact on the crank. It will over tighten the nut and the hammering can't be good for the crank. Quote Link to comment Share on other sites More sharing options...
registered user Posted May 19, 2014 Report Share Posted May 19, 2014 (edited) turning it with a ratchet. no carb,reeds or pipe hooked up. whats wrong with this picture why you fooling with this nonsense anyways. matt shear even said the kicking comp was useless and i have to agree Edited May 19, 2014 by registered user Quote Link to comment Share on other sites More sharing options...
turbowrenchhead Posted May 20, 2014 Author Report Share Posted May 20, 2014 It's not useless. Over 150psi running 93 or less is risky Quote Link to comment Share on other sites More sharing options...
WINDYCITYJOHN400 Posted May 20, 2014 Report Share Posted May 20, 2014 Yes it's useless. Bench testing compression is a joke. A good builder will calculate the compression, then back up the calculations with an actual measurement. (You were told how to do it.) Liquid measurement of the compression volume is 10 times more informative than kicking compression anyway. Kicking compression is the common man's way of getting a close idea of what is going on compression wise. A liquid measurement is the only way to truly do it effectively. On another topic - if you raised your exhaust port 2mm over that last motors porting.......you just tossed out all your bottom end power and now need a drag pipe to match your porting. BIGGER IS NOT ALWAYS BETTER. Quote Link to comment Share on other sites More sharing options...
turbowrenchhead Posted May 20, 2014 Author Report Share Posted May 20, 2014 I can do the liquid test. I'm not sure how to covert that into a compression ratio. I raised the exhaust port 1.6mm. I brought my cylinder down with a thinner base gasket .010. My squish is at .045 with this combination. Quote Link to comment Share on other sites More sharing options...
BUILDER Posted May 20, 2014 Report Share Posted May 20, 2014 . Did you try with an impact yet? Dude seriously before you keep giving this advice you need to try it on your own quad and see what happens! Some newbie is going to try it and break the end of his crank off!!!!!

WINDYCITYJOHN400 Posted May 20, 2014 Report Share Posted May 20, 2014 are you sure that isn't his plan for the OP? LOL ^^^THIS^^^ They start top fuel cars from the supercharger belt. Stands to reason someone would dream up trying a drill. Try a nice Milwaukee right angle drill. LOL Quote Link to comment Share on other sites More sharing options...
BUILDER Posted May 20, 2014 Report Share Posted May 20, 2014 LOL I would use a air ratchet if it were me Quote Link to comment Share on other sites More sharing options...

BUILDER Posted May 20, 2014 Report Share Posted May 20, 2014 ^ so I joke and it's fuck me. You joke and it's cool? You were joking when you ask him in 2 different threads if he had tried to turn it over with a air gun yet? I call bull shit dude nice try but you were not joking!

trickedcarbine Posted May 20, 2014 Report Share Posted May 20, 2014 If you look up, I knocked on the ratchet idea from the get go so I thought it was clear my following response was pretty fececious. But hey, just from now on, I'll make sure to but in a girly LOL or JK so it fits your Facebook humor. Quote Link to comment Share on other sites More sharing options...
camatv Posted May 20, 2014 Report Share Posted May 20, 2014 what a joke. how about just put the motor in something and see if it will start.. i use cranking comp to check if a motor should run if it wont run. usually you can feel if comp is to low just through pushing it over by hand..

registered user Posted May 21, 2014 Report Share Posted May 21, 2014 your farting around way to much with that gauge imo. which probly dont work right anyways because half of them never do concerntrate on something more important like getting a nice exh shape Quote Link to comment Share on other sites More sharing options...
turbowrenchhead Posted May 21, 2014 Author Report Share Posted May 21, 2014 I did the liquid test. I can get 14cc's of oil into the chamber when the piston is at TDC. I have no idea how to convert that into a compression ratio. I looked online and they want a dome cc height and I have no idea what it is. Lil help here please.

turbowrenchhead Posted May 24, 2014 Author Report Share Posted May 24, 2014 Got the motor back in tonight. I put 22cc domes in it because my uccr came to 14:1 with 21cc domes. I got 160psi cranking compression with kick start. I need 23cc domes Quote Link to comment Share on other sites More sharing options...
