Just needed some advise from some of you that are running Ferrea valvetrain in your race engines.

I'm in the process of getting parts together for my build this season and I have decided on going with a full Ferrea valvetrain setup. I'm talking valves, spring seat locators, valve springs, retainers, valve locks, the whole 9.

My hang-up is trying to figure out what part number of spring I should be running. Ive searched and really cant find any useful info on this.

I'm running Skunk2 Pro1 cams in my head and it looks like the Ferrea part number of the valve springs that I need to use is S10064. Is there any guru's on here that can confirm this for me?

Specs on these springs are:
Seat pressure- 95lbs
Open pressure- 215lbs
Rate/inch- 305lbs
Coil bind- 19mm
Max net lift- 14mm

Thanks in advance guys.

 

I called them about the pro 1s and gave them the spec of those cams and they told me the part number of the springs i needed was s10027.

 

Ya I looked at that part number but wasnt sure about them because on the Ferrea site it listed the S10064 as a "Turbo" application.

 

Jit...run the heavier spring

 

Are you talking about the s10027 springs Luke?

The specs of the 2 springs (s10027 and s10064) differ but would it be just as simple as going with the heavier spring?

S10064
Specs on these springs are:
Seat pressure- 95lbs
Open pressure- 215lbs
Rate/inch- 305lbs
Coil bind- 19mm
Max net lift- 14mm

S10027
Specs on these springs are:
Seat pressure- 100lbs
Open pressure- 220lbs
Rate/inch- 305lbs
Coil bind- 20mm
Max net lift- 13.5mm

 

Neither. I'll be back in the country Tues/Wed give me a call and I will show you which springs. I have them at the shop.

 

Word. The next size up that they have is the S10086 which says "This spring requires Ferrea Roller Rocker #RR1000"

......

Luke, what are you trying to get me into?!

 

using pro1s too with sk2 spring and rets

but most of the guys who has custom webs and pro1s suggest and are using the ff ferrea stuff

Valve spring - S10027
Retainers - E11000

 

Thanks for the input! How long have you been running the Pro1's with the s2 springs and retainers? What are the specs of the springs you are running? My plans are to mainly run my car at the track, but I will drive it around town on the weekends. I just dont want to induce alot of valvetrain wear if I can avoid it. I plan on keeping it below 800whp.

 

around 2years with minimal street time on 800-900+whp

was asking around too regarding the part nos. for ferrea stuff cause im planning to upgrade to together with a custom webcam.

 

I venture to say that eventually I'll run a webcam setup with roller rockers but for now I just want to get the car together and make it last to where I can learn how to drive it

 

im planning on using standard custom grind webcams not the rollers ones...

revving it up to 9800-10k

if i can do it all over again, i will go straight with ferrea...

 

Web does not make roller cams.... FYI

Go web and never look back.

 

I went Web and went backwards....

 

Uh oh.

 

Good for you. Smh

 

I speak from experience. Something you know nothing about.... I (Unlike you) have REAL TRACK DATA.

 

All hail Rick!

SMH

 

SMD..

 

SMD....Lmao !!!!

 

Hey guys, i have WEB Pro series cams for B18C. Which valves, springs + retainers, locks & valve seals are best to use with these cams ?

 

do u mind sharing your experience with Web, and what you use instead now?

 

Stock camshafts

 

Does anyone else have any input on which Ferrea springs will best suit my application?

 

I'll just say that stock cams out performed them BY a mile in everyway possible..

I have not run stock cams in a while. I did run Pro1's (should of tryed Tuner2's) for a while and they are by far a better choice over the Webs. Even thought they are bigger then the Webs they spooled better and made alot more power. Just an over all better choice..


For this year I stepped out side of the box alittle to try something that I've learned from testing a bunch of different cams.. So far I'm quite pleased with the results but, I only have a hand full of passes on them now. Only time will tell.
