sir gud pm.im using cms valve spring it is good,but after a week i noticed that there is a weird sound from my engine,the sound is very stiff and loud tik,tik,tik,tik,,,is it normal???

 

[Cesar Ablao]

Check your valve adjuster, valve clearance, and valves. For sure something is wrong now.

tnx sir,aftr holiday

Here's the JVT valve spring. (sir mon pahiram po dito ha. )Promotion na rin =).
As you can see, theres a specification for the stiffness: 2.8/47.8L or 3.57 cubic inch. Can anybody show the specs of CMS valve spring? and also for the stock valve spring just for comparison.

Php 1,050.00 to be exact sir. Hmmm still undecided on what valve spring to use. Since there are many issues concerning the valve adjuster and valve tip being damaged by using very stiff valve spring. I hope someone could post the profiles of the different aftermarket valve springs like JVT.

Maganda ang cms talaga sir. Pero ayaw ko gumamit dahil matigas masyado.

Nag try kana change ng Vspring mo?

 

[Cesar Ablao]

N

Nag try kana change ng Vspring mo?

Not yet sir. Thats why im asking those who have tried this product for some feedbacks before i buy 1.

Based from the pictures, jvt has 8 to 9 coils while cms has 10 ithink. So cms is stiffer compared to jvt.

Maybe il end up using jvt.

 

[mac kevin]

for me vixion vs or jvt is less stiffer than this high quality VS, like cms, yy pang, tk, etc.

vixion vs=P1,700.00
jvt vs=according to you P1,050.00

quality and stiffness almost the same..

if I rate the two in percentage:

vixion is 99%, while jvt 89%,

@mac kevin

Sir what is your percentage basis? Is it according to price? If it is according to quality, how did you check this and come up with the percentage values?

I have read some threads that mtrt or the valve springs from taiwan become less stiff after prolonged use. But according to some drag racers here at pangasinan, jvt is better than mtrt.

Perhaps stiff valve springs like CMS are good for big valves? Are they? And not suited for stock valves?
