isky valve springs
Turbo Mini Forums

has any one used isky valve springs and are they any good

well they were good in there day... and still are .......... many years ago english spring manufactures got a bad name for springs production...... they were little more than junk hence ever one raged about isky springs 20 odd years ago.

the minispares double valve springs are top quality, also the piper ones kent etc ..... dont go over poundage on the valve train by overloading it with insanley pounded springs, say 300lb ones when the engines only going to reve to say 7000rpm ish 180 pound ones are fine and capable of 8000 rpm with out valve bounce and dont overload the valve train.

hope this gives you a little insight

benross, do you mean the springs are rated at 180lb max or do you set them at 180lb at full lift using shims under them?

Speeding is like masturbating, everyone does it, but not all of us film it and put it on the internet

I always used Isky with great results, one got a bit weak so Pete Baldwin recommended Minispares which were shit - they bounced at 8,500 rpm so I now have Swiftune springs which are fantastic

I seriously doubt it!

When yopu fit spring correctly you would shim them to the fitted length specified by the manufacturer/supplier,

isky springs have two fitted heights from memory, one length named "sprint" , the other "super sprint"


a correctly fitted supersprint genium Isky spring will allow as mkuch as 0.570" valve lift,
