Clevo120Y 815 Posted August 24, 2013 Looking for peoples feed back, I just bought a digital valve spring tester and wanted to just make sure it works, put a stock crossy spring in it, compressed it to 1.8in and got a reading of 30 pounds, that is seriously low, has anyone else tested them before, also I tried a stock Windsor spring and got the same result.

slydog 7,873 Posted August 24, 2013 I think Clint and Q may have ventured that way but I never have sorry... Share this post Link to post Share on other sites
n00bus m@x1mus 465 Posted August 24, 2013 Ive done rough tests using a set of household scales under my press and when squashed to the installed height i got around the 60lb mark for stock springs and around 90lbs for an old set of 110lb double crow springs. You could try a similar test to compare your digital unit.... is there any calibration instructions to follow? Share this post Link to post Share on other sites
Clevo120Y 815 Posted August 26, 2013 I'm a dumb arse LOL had it set to kgs, and Clint I agree with your findings, stock springs ranged from 56 to 64 pounds at 1.8 inches. 1 n00bus m@x1mus reacted to this Share this post Link to post Share on other sites
ando76 4,354 Posted August 26, 2013 Always the simple things that get us, Tee hee. Gee that's puss spring rates - no wonder they bend pushrods - did someone say valve float..... 1 Clevo120Y reacted to this Share this post Link to post Share on other sites
n00bus m@x1mus 465 Posted August 26, 2013 Yeah i know. I went ages chasing my tail with ignition advance and injector flow trying to aleviate a horrible drop in power at 4200rpm.. it was like a rev limiter, back off to 4000rpm and it would spring into life again. Someone suggested i get new valve springs and hello 6k no probs. Share this post Link to post Share on other sites
ando76 4,354 Posted August 26, 2013 Yes I imagine that the poor old valve would have been in a state of shock at those rpm with that poundage, but then again these engines were built for a purpose and going to 6000 was never in the plan. Share this post Link to post Share on other sites
