Upgrading Valve Springs Jay's Tech Tips #23

We're back today with a new Tech Tip from Jay as he explains what we need to know about valve springs!

[@abadmixtape]

These videos are simple and informative. Whoever edits these does a really good job. I don't even care if I need to know about the topic covered in the video it's that good of a series!

[@MYDADSTHEMAYOR]

This was a legit 10/10 tip video, really great mechanical advice!

[@xDivinitysCreaturex]

A++++ for the keeper comments. Was prepared for this, then my Dad had a go...two week wait from Italy for new keepers.

[@FPKMASSACRE]

If I ever own an mk4 supra I'm definitely going to real street performance to tune it! This guy knows his shit!

[@trifonovbg]

Very interesting and important! Great work doing all that educating videos. Awesome,keep doing the great work,I hope people will appreciate it...

[@SpartanTimTv]

American turbo yoda!

[@RicanSoldierBoy]

Evrytime i see one of your vids, i get the urge to build a block lol Thanks guys!

[@bshawn41]

Love these tips guys! Keep em' coming!

[@boosted2.4_sky]

Thanks again Jay...I'm building in two weeks and I kept flip flopping in whether or not to go up on my springs (doubling boost) stock springs are 58# will be moving up to 75#Supertech keeping the cams stock and getting new retainers and keepers...and seals...thanks again!

[@ItzSillyy]

These vids needs more likes! These are pretty helpful! Thanks jay!

[@johnnymac1976]

Do a video on quench depth... theory, measurement and ways to adjust it. Max and min for different engines and piston types. Thanks for all of the awesome vids!

[@griffsrearmountturbothemod1623]

Thank you Jay for the tips... well said..

[@dyn0mitemat]

Good vid, another tip is to get a metal scribe (or long thin screwdriver) and put a neodymium magnet on the stem somewhere, works like a charm for swapping keepers

[@trentdean3973]

I think we can all agree that this is way more informative than Supra forums for us JZ guys lmao

[@keltalon]

Good job fellas well explain if I have to say so myself lol! Thumbs up on this one!

[@ColAngus]

I really learned alot,thank you for posting this. :)

[@ryansalazan]

First off would love to say thank you for all the tips! I have learned a good bit of information from watching your videos even after being pretty well mechanically inclined. With all this being said, I had a quick question. I'm running a 4 cylinder turbo application and pushing some pretty high boost levels (between 35 and 42psi). I'm still on factory valve springs and though the motor runs great and is making good power, Would this have negative effect on power or more importantly spool effect? I feel like spool time is a little slow for me and spool recovery in between gears is a little hesitant. I would love to hear your opinion. I already do have upgraded valve springs and titanium retainers and new valve seals on hand, but have just not put them in. Thank you for your info!

[@05cr125rider]

in what situation would the behive springs be beneficial over the dual springs or vice versa?

[@thecalii9280]

Best tip so far! (My opinion!) Keep them coming! That's what she said! Yea I know

[@abscrypto]

rly helpful tips and knowledge about autos thanks for the amazing job all the way from Dubai :DDD thanks jay's

[@daniel2064]

i have aftermarket beehive springs....How long do they last on a street driven (no track) weekend warrior...??

[@BoostedMarcelo]

I'm going to be installing stage 3 cams and beehive springs on my SOHC 3 valve mustang and is there any break in process I should follow? I was told there isn't since it isn't a flat tappet cam

[@jeangenibrel2358]

When do you need a cooler for the valve springs? How do you plumb one?

[@foxybat4774]

wut valve upgrade do u recommend for mazda f2t motor? (2.2/turbo)

[@jjmccloud]

I have a new set of ls6 blue springs to use on my sbc 350 aluminum heads will they be ok for a hydraulic flat tappet cam they'll be installed for either 90lbs or 110lbs seat pressure

[@kd2833]

if i change just the valve springs on a suzuki swift 1.6 zc32s can i rev 1000-1200 rpm higher without other things i need to change ?

[@SchaferTheRicer]

This is like BuzzFeed for cars

[@einartasvaitkus8096]

buzzfeed is a bunch of idiots. This guy knows what he's talking about.

[@Giixxersquid]

I think that was the best tip you dropped yet

[@RecreationAutomotiveGarage]

Is there any ways to tell between gsc stage 2 and 3?

[@observingrogue7652]

I'm extremely interested in solenoids. I don't like the turning resistance because of the springs & valvetrain. I can have the AC, water, and oil pumps, run off of electric motors, so the only thing taking power from the crankshaft, is the alternator. And until I replace the springs with a computer, them too.

[@jasonb938]

Magnetic pen works well for getting the keepers when removing the springs. Do not be cheap and get a good valve spring compression tool. If you are changing valve springs while heads are still on the car, either KNOW where TDC of your piston is located or have a air compressor tool that will hold the valves up... both is at once is recommended... if the valves against the head drop and you lose cyl pressure you will still drop the valve.

[@MarvinConnell]

Is there a % by which stock RPM can safely be exceeded?

[@pebblez_]

Whats best for all motor vtec?

[@noel1553]

Not that it's relevant but I love that yall stay on point with the music. What's the name of the songs that were used in the video?

[@Andy-1094]

anyone know the name of the beat they used for the video?

[@joestro7826]

Right On thanks

[@PressureEd]

Love this

[@duncan19899]

MUCH BETTER INTRO! FOR REAL!

[@stevenposadas1471]

What's the beat in the beginning ?

[@ubpak7346]

I have not enough English please answer me he prefer to single valve springs or dual valve springs?

[@theedge5584]

How to know what lbs. spring I need for a build????

[@inmymemory507]

More vids like this please

[@camperzbware]

When upgrading to stage 3 + cams, would I need to upgrade my Pistons as well? That has a suitable valve relief

[@dyn0mitemat]

Sergio Ramos For what a model-t? a cobra? a motorcycle? calculator?

[@alexanderknight7793]

You need to add the new Conical Valve springs to this video, since it does a better job and frequency dampening than the beehives or dual.

[@viperaljabri9830]

Hi I have ls400 98 i want to put some part that increase performance ....so i need your advice...I want my car to had 360hp

[@justinbeamon6624]

Nice cam and good tune with exhaust should be great. Not sure what the aftermarket is for those but those engines sound great with a cam and exhaust.

[@hugoortiz05]

Why weren't triple and conical springs mentioned?

[@williamgrand9724]

Get pneumatic valve springs, you'll never float a valve!

[@Sundara229]

2:05 Duratec HE, isnt it?

[@michaelleighton3130]

Thànks !!!

[@jasaircraft]

Can you guys please make an example vid showing the symptoms of a valve float issue? I believe im having that problem on a 2jz-ge thats been turboed and has copied bc 272 cams (because there where non offered for the ge).

[@Jimi8512]

Valve float is when the RPM of the valve train is so high that the spring does not have time to extend fully before the rocker comes down again. Meaning that you would see a compressed spring that never seems to move back to its uncompressed state. The symptoms of this is that the valve would never close and collides with the piston.

[@jasaircraft]

@@Jimi8512 by symptoms i meant how the engine sounds/behaves when this is happening and also what happens to dataloged signals.

[@nezerac]

I'd be interested in learning when and where to use each valve and the types of applications that would benefit from this. I have an SOHC that I'm trying to get more rpm's out of but the cam isn't necessarily built for it. After market cams are impossible to find for my car so I was thinking how would advancing the cam and using a strong spring for higher rpms work vs spending a ridiculous chunk of change for a completely custom valvetrain.

[@jacktorrance7847]

nezerac Just go for a re-grind

[@nezerac]

Jack Torrance It's got rollers in it. Not sure how you'd make up for the base circle being smaller.

[@fijiislandlife8224]

have you tried upgrading your ECU

[@nezerac]

Navishaal Chand No not yet. I'm thinking that I'm gonna go for a 1.6 head from the uk as well as burton power valvetrain bits. I want 7500rpms and solid lifters.

[@jacktorrance7847]

nezerac They weld up stock cams to get extra duration and lift on a re-grind.

[@booostedtc]

Do you need springs if your still running stock cams. If you have the rpm raised in the ecu. Say 1,000rpm over stock reline would you need to upgrade the springs for this

[@MrNuggetface]

A smart man would and should.

[@justinbeamon6624]

Yah for 1000 rpm you should definitely replace it. But keeping a stock cam means your power band will not improve at all.

[@kinggg313]

justin beamon unless, u install higher ratio rocker arms, which will in turn, increase lift n push ur powerband higher. Making more topend power

[@evansjustin2459]

What's the song

[@phareztrinimand]

What is that sound intro ?

[@nestr2007]

Dose of knowledge :)

[@truthman8302]

great video. ty sir. you should make more educational vids.

[@enginebuzz5741]

Klassick!

[@TheStriker0525]

can you do a vid on fuel and engine oil.

[@realstreetperformance]

Gary Hamill Hey Gary! We just released a Tech Tip today which is all about picking the right fuel system components for your engine! We hope we have answered your questions and more! Check out the video here on TRC's KZbin or ours! Have a great day!

[@3rdGenGuy]

$60 LS6 springs FTW!also, some OHV engines are 10,000 rpm capable so i wouldnt say a DOHC necessary revs higher.

[@banddude121]

PC Master Race And some DOHC are capable of 20,000rpm. DOHCs do rev higher and that is why they are used instead of OHV.

[@3rdGenGuy]

Porsche Curves those 20K rpm engines don't use valve springs lol. Do you even race?

[@cyclecrafttom]

PC Master Race normally, engines above 16krpm are using pneumatic valve system (just like MotoGP engines or F1)

[@3rdGenGuy]

cyclecrafttom Exactly, so that isn't relevant to this valve spring video lol. While 10,000rpm 10,000 horsepower top fuel engines use valve springs and OHV.

[@mikeloch5033]

Not for nothing , but did his beard grow in while making this video ? Watch the beginning then look at him at the end , AWSOME video btw !

[@VennyCardenas]

Is this 4k video? Great Cuality

[@dominikkus1134]

Quality* (;

[@VennyCardenas]

Haha I was trolling❓😋

[@dominikkus1134]

Ok u got me +1 for you haha

[@valterponte]

What happen to your beard? it grew really fast in the end of the video !

[@Fubar231]

Why doesnt he talk about conical valve springs? Comps been talking about then alot lately and say there better than both double springs and beehive springs.

[@theedge5584]

THEY NEED TO START MAKING ELECTRONIC CONTROLLED VALVES NI CAMS

[@bufalong]

change tires give more powder

[@1atinlove]

Far, far, far...awaaaayyyyy...never to be found again. There is a bermuda triangle for those suckers.

[@bootyman234]

How do you go UP to a single spring when that's what you start out with? You don't start with NO springs then go to a single. lol Jus messin wit cha. =)

[@dominikkus1134]

He grew a beard so fast

[@Dungzoo]

I wish I could grow one that quickly.

[@Pyr01]

why are they so expensive

[@TonyBMW]

9000 rpm Malàka!

[@evanwallace1744]

yo can I buy all this shit from you guys

[@kylegibson5402]

Imo this clip was a great idea but not informative enough. You should of added that cylinder head castings are not always the same. As with valve stem height. Spring seats often vary, even from each other on the head. And to get your ideal spring rate at the seat each spring needs matched to the spring seat/valve by shimming. You can't just get a mass produced valve spring, throw it in a mass produced head and expect certain spring pressures by just throwing them together.. To many variables.

[@Damicske]

Mazda still develops engine's without valves anyhow :D they are called Wankel engines.

[@FUCKPOTATO]

sorry(hi for my bad English)

[@Vegatable]

Just got supertech titanium springs and retainer for my honda 🏌️‍♂️
