So I have been looking at Valve springs because I will be running the Cosworth M3 cams. I have one friend who swears by the Kiggly Beehive springs. Im wondering what you guys are running and how things are holding up. Any other advice is appriceated. My plans are to max out a FP Green on E85.

Thanks fellas

 

Ive taken them to 10,700rpms with no problems

 

Thanks for the info Paul....I think I PMed you about this. Im not sure if the springs may have too much pressure and eat up parts...this may sound silly, but Im a push rod guy...so Im looking at lifter life and things like that. Would these springs have ill effects on any parts you could think of?

 

Not sure i know GSC Greg setup my head and the springs are shimmed to the max with his S3 cams. I would PM Greg and get the details he would be the man to know. There is no unusual wear on them so far. You could pm Kiggly also very nice guy

 

Cool thanks, I guess Kiggly doesnt post much here...just looked 5 posts, lol

 

Yes there is a happy medium with seat pressure.. you can have too much seat pressure which will beat up the seats and also rob you of power.. not everyone is revving to 10k+ so there is such thing as too much spring..

 

I only plan on revving to 8500 max...Im just doing it for safety. I dont plan on doing big Rpms. What would be a good happy medium? Also, someone told me the IX has Titanuim retainers from the factory...so all I need is springs, is that accurate?

 

I looked at them, but didn't plan to take my revs that high. Instead I went with the BC springs/retainers, Mike@awdmotorsports hooked me up.

 

I had the BC Springs and took them to 9200rpms before they started to float. Good price on them for someone on a budget

I plan on using SuperTech singles on M2's w/ my green...i know a bunch of local guys are running them w/o issue.

 

They make 3 different supertech duals..I beleive ~60lbs,90lbs,120lbs.. at 120 lbs of seat pressure on a car that isnt running a big cam and revving high it has to be beating up the valve seats but my experience is limited on headwork with turbo cars.. I am relating this back to bikes that rev 13-15k. i only run 70lbs of seat pressure on my big bore stroker busa.. Of course you need a little more seat pressure on a turbo car as they spin up very very fast..

 

The Kiggley are great springs!

Paul i believe your head is setup at 105 seat pressure which will coil bind at 12.9mm of lift @ 105 seat pressure....

I will be running the Supertech 120lb springs unless something else comes through. With the GSC S3 cams they can see 10K rpms with 100 seat pressure. So with the 120 Supertech's that would be 313@11.5mm so 12Krpms is probably capable.

Ok fellas Im looking for a recommendation. Im doing the springs with the head on the car....stock internals...just looking for safety...do the IXs have Ti retainers from the factory.

 

You honestly can probably use BC springs and retainers for what your doing.. If you wanna spend a little more because you know down the road you might be looking for more power/RPM then go with supertech ~90lb Duals.. I dont know if IX retainers are ti.. even if they are they wont sit proper in certain aftermarket springs anyway..
