A Very Little Info About Valvesprings

[@BudgetBallinGarage]

Great video! Lots of need to know information here! The numbers always kinda boggle my mind lol but I'll go back and watch it a few times and it'll all click 😂 thank you Eric!

[@CherezianRacing]

Never knew about the coil bind surge deal. Thanks for the info

[@richardoliver1303]

Excellent Explanation!!!

[@cfmechanic]

So much info. I learn every one I watch. You also helped me to get my dragon slayers up to par with the spring Id locators when I had machine shop port then and replace guides. Thanks

[@MrRandy3504]

Great vid and on time for me bought a set of used dart 230 heads with jessel shaft rockers for 1500 couldnt pass it up anyway the springs on it wont work with my cam im a little over what they are good for and this vid helps me to understand why and how of it. Ive got my machinist taking care of it but i want to understand what is happening and this vid did shed some light for me. Thanks keep it up

[@chrismadaj8751]

Eric been watching your videos for about a little over a 1/2 Year when I was younger i mildly ported heads. which got me interested in your KZbin channel. I really like the way you explain your stuff but you have so much wisdom on HEADS valve trains and this is just my opinion you always try to appease the things that you are great at i think you you don't give credit were credit is due. but hey that's just you really appreciate your knowledge God bless

[@alexmaccity]

I worked in a spring shop for 3 months. I had to load a grind machine by hand, shot peen, and lube/wash machine, and a coiler. only cool thing we did were the springs for the trunk on that honda truck trunk in the bed

[@Hammerback0]

Hmmm. Lots of good information. Have to pass this along to the garage engineer. 👌🏿

[@bdugle1]

Great video, lots to know! Sounds like I go to the professional (you) when I have a specific application. Thanks Eric!

[@allenbrixey1122]

Good video. The rate can vary by the coil count and diameter. Wire size also dictates this at load height and installed height. Looks like they are all right hand wind and left on the inside spring. I'm sure all the springs are out of chrome silicone or chrome silicone valve spring wire. The shiny ones probably have been run in a tumbler for a while. Most of the time they are stress relieved at 800° shot peened for four minutes after grind then recook at 450° after peen. Your correct on the retainers matching your springs. I use a digital Larson tester with a 1000lb load cell to check these. If you could get the retainers you could have your springs made here in Tulsa.

[@patrickharper9297]

Love the PSI valve springs!!!

[@lawrenceskrobarczyk4402]

Good info thank u

Exceptional video as usual.Thank you

[@ericsmcmahan]

What are your thoughts on conical springs? Do you use many of them?

[@Mustang_Chris]

I'm thinking the same thing.

[@WeingartnerRacing]

I haven’t run them yet mostly because they are a large diameter that most spring pockets will not accommodate.

[@dondotterer24]

How about conical valve springs?

[@hotrodray6802]

🔔😎 Excellent. Thank you Sir 👍👍😎

[@claibornewoodlief8310]

Eric I had to use a all set retainer one time on motor I was working on and to get extra clearance in between the rock arm I used the last cap it worked fine and I turned that engine 8,000 never had a problem just something to think about

[@pablojanski.2559]

Beehive and conical vid , yea.. On hyd rollers, I been using beehives for years and love em.. aside from the danger of them. I never had a failure, but I have seen some and it;s ugly.

[@grahamh2758]

What spring pressures for a solid flat tappet?

[@Aheitchoo]

Thanks man

[@22rockcrawler]

Can you do a video similar to this with valves? Go over different styles and how to select the correct length?

[@isaackellerman3006]

I had two options for my engine .550 lift springs or .650 lift springs

[@peterchristlieb]

Been using the PSI 1224 for BBC stuff up to .750 lift. Works great.

[@WeingartnerRacing]

You could have used a 1225 and set it up at 1.950 and had same pressures and the spring setup would be lighter.

[@peterchristlieb]

@@WeingartnerRacing Blown engines, I might try that on the injected car though, thanks Eric.

[@hotrodray6802]

@@peterchristlieb If it's the same seat and open pressures, why would your heavier weight spring be better?

[@peterchristlieb]

@@hotrodray6802 Different installed height, I probably have a longer valve

[@QXZ9027MKII]

Much obliged for the insight Sir, scintillating indeed. Would you mind sharing the brand of that spring compressor or where to buy.

[@spencerlancaster1518]

Just wanted to say I always look forward to your insight, knowledge and opinions. I recently did some reading on conical springs and though I haven’t run them was curious if you had any input on them.

[@WeingartnerRacing]

I haven’t run conical springs yet.

[@edpetrocelli2633]

I ordered conical springs from comp in march of 2021 never saw em, canceled them in november. never heard a word from them. They look good on paper, very high resonance frequency. no need to take them close to bind.

[@FABRIC8TIONUNLIMITE1]

Old School K - MOTION on mine, I'm "in that situation".

[@havebenthere]

What's your opinion about this scenario... I have AFR 210 Eliminator heads. Want to run a S roller with 273 duration 700 lift. AFR says the spring which is Pac 1243 240 @1.90 ih. not to use it for over 260 duration at .050 or .710 lift, rather upgrade. Upgrading to the next spring which is the 1225 will give too much extra spring hgt due to being for .800 lift and 2.00 ih. So looking at more possibility of spring surge. Also AFR recommends only 5/16 pushrods due to clearance issues at the pinch I believe. ie. pushrods flexing more. Currently cam is S roller .645 lift 260 duration 264 ex. .110 wall 5/16 pushrods and titanium ret. Is AFR just being overly cautious as Erson has a Spring similar to specs of the AFR (Pac) 1243 and they seem to recommend for v much more duration. Pretty much apples to apples with these 2 springs. I've had this scenario before on customers heads non AFR most time they were running .735 approx lift so decision was easy.

[@xlr8r3VA]

Good information Eric, as always. Any particular reason why you don't like Comp? Anything the average street guy should know about Comp springs? Also you didn't get into standard vs beehive vs conical. Do you have any preferences there? Thanks! I hear conical is the best of both worlds.

[@shadowopsairman1583]

Im looking for a Dual Valve Spring for LS 862 Heads (LR4 4.8L) I will be using a Brian Tooley Racing Truck norris Cam, They Recommend LS6 springs. Can I find a dual spring that has comprobable specs to the LS6 Spring? I am just looking to increase durability and a fail safe.

[@GrimReaper-yp1mo]

What about afr 220 630 soild roller pac 1225 260 270 s psi 250 ok will it work

[@brianholcomb6499]

You get what you pay for with valvesprings! If you have a "STAGE" whatever, L/S hydraulic roller. Run the springs the camshaft manufacturer recommends! Normally the beehive! But if you are running a real camshaft, you still should be talking to your cam manufacturer! They need to know what heads, what valves, & what you are doing with the engine! Good Cylinder head guys can get you close! But your camshaft guy knows & has tested there cams normally on spintrons & dynos! If you want, or actually need a top quality spring. You need to plan on spending more than a couple hundred dollars! They are more expensive [Sometimes double a cheaper spring] & they absolutely need the correct corresponding parts, & the proper setup! If your the type that buys cheap Ebay china shit, especially fully assembled heads, you best take them to a quality cylinder head guy. Like Eric. Because I've seen BBC heads come through w huge double springs, that had less than 30lbs on the seat & less than 100lbs open, you could pop them apart by hand 🙄🙄🙄🙄! It was amazingly bad 🤣🤣🤣🤣! We also had a customer run a assembled set of china garbage. The way he found out things weren't right, was by dropping multiple valves, on the first test drive! [What a fcking mess] Also if your not sure about setting up valvetrains, or if you think setting up a valvetrain is bolting rockers down on a L/S, you probably shouldn't be doing it! Dropping a valve, normally destroys the whole engine! If you look up valve float on you tube, I think Pac made some slo motion videos years ago! If you want to see how fast you could wear out even the best parts, in your heads. See the valve float videos! Thanks again Eric, & as you said, you could make many videos on just valvesprings! I think Steve Morris put up a bunch of videos about valvetrain, if you look up his Steve Tech! I'm sure our other cylinder head buddy did also! But that's up to you if you want to mention him! Have a great end to your week 😂😂😂😂!

[@briandavid3159]

I thought every cam has a set up to it check out the cam card to determine installed height And seat pressure for a specific cam check manufacturer of the cam Not very complicated

[@7080nik]

Eric, I have Manley springs on a BBC with .773/.744 lift- 276/272 @ .050. Its a Straub cam with Straub supplied Manley springs. I believe the seat pressure is supposed to be around 235 lbs. I have the springs set to around .050 to coil bind. With an on head checker and the off head, I am only getting around 190 to 200 on seat. I told this to Straub. He told me to check for any wear pattern on the valve stems. Everything looks fine after some hard street driving miles and the 13 engine dyno pulls we did. The intake valve is stainless @ 2.335 Tony Mamo ported AFR heads. The light seat pressure makes me a little nervous but I have seen lots of guys running real light seat pressure on much larger cams than mine thanks to spintron testing. What is your opinion on this? Thanks!

[@apw30534]

What ever happened to K-Motion valvesprings ? Those use to be "the best" back in the day. lol

[@WeingartnerRacing]

Went out of business

[@blueyhis.zarsoff1147]

no beehive or conical springs in your video?

[@jeffjones4040]

You hit on it a little bit, but what are the limits of the hydraulic roller. Which lifters can handle the higher loads and practical limits of lift and spring pressures?

[@WeingartnerRacing]

It depends on the brand of lifter.

[@nickwheaton1527]

You doing much with beehive or full conical design springs?

[@mikew6135]

Reduce float with TI valves

[@WeingartnerRacing]

If people can afford them its always a good idea.

[@freeradical431]

No beehives?

[@WeingartnerRacing]

I use them on hydraulic roller.

Nice video Eric. I was planning on running a Crane solid roller in my 454 bbc Corvette. The cam actually came from a mercury marine engine. It uses Crane CDS series lobes meant for oval track endurance engines. The cam has .672 lift, 252/257 at 50. What valve spring would you recommend for this cam. Thank you.

[@grngs1]

do your research

[@stevenshepherd1905]

Can you make a video about engine operating temperature? How hot can i run my engine before components start to fail?

[@austindoud273]

Lol keep it below 240 and you'll be alright

[@ronnieb7408]

Conical and Beehive springs?

[@WeingartnerRacing]

I haven’t used conical yet because the good ones take a big spring pocket but use the behives often on hydraulic roller.

[@chickenfoundation9323]

What would you recommend for Howard’s cams 111145-12 with 1.6 scorpion rockers and eBay heads

[@WeingartnerRacing]

I don’t know that part number.

[@mikeleschber33]

What do you think about Isky Tool Room or Manley Netek? I have had good luck with them.

[@WeingartnerRacing]

Isky is made by psi and I use them quite a bit. I don’t like Manley.

[@chevyluv7216]

@Eric at what lift is there an issue with a solid roller cam on the street for a bbc? Which springs do you recommend?

[@WeingartnerRacing]

Above .800. I only say this because none of my customers have made 1000s of miles with above that lift that I know of.

[@timothyarnott3584]

Hey Eric, Tim here, gotta question.......when i re-did my KRE Poncho D-ports, (had to as i bent a few in the mass carnage of a 6,000rpm engine failure [lost a rod, and everything self destructed]) i used the spring mic for installed height (bought new springs that Kauffman uses for those heads they are comp).....i was able to get + or - .015 from what the sheet said.....Jeff (Kauffman) didnt bat an eye, but i've been wondering if i shuda stayed tighter to what the sheet said.....car runs awesome, but i have a custom Kauffman grind to put in, to get me to 10:80's or so....(i'm at 11:0's @ 120, 7 flat in 1/8th).....is +/- .015 ok on a solid flat tappet?........dunno if you can take the time to respond, but this vid got my wheels turnin in my head.....if ya can answer great, if not, i understand.....GREAT vid!!!.....ALWAYS stay to the end!!!!..PEACE!

[@WeingartnerRacing]

0.015 makes very little difference on lighter springs for flat tappet cams.

[@timothyarnott3584]

@@WeingartnerRacing Hey Eric, Tim again, TY SIR!!!.....i deeply appreciate ur time!!!

[@cfmechanic]

How about isky springs good or cheap

[@WeingartnerRacing]

Isky springs are made by psi. I use the tool room ones often.

[@speedracer412]

is there a difference in ON seat pressure for turbo applications ?

[@WeingartnerRacing]

Yes you must add more to make up for the pressure on the valve from boost or you will have valve float.
