Short Valve Float Movie

Short Valve Float Movie

[@TheShawzy]

just to clear things up, im a motorsport technician and have a degree in motorsport so i know what im talking about. valve bounce is when the valves do not stay in contact with the camshaft lobe and valve bounce is when the valve doesnt stay in the valve seat at high RPM because of inertia forces. thanks for your time

[@Tater4200]

you said valve bounce twice lol

[@theozman38]

Springs with lots of miles. 100k it’s time to change. Plus.,, if your cam is bigger than the spring rate and lift or heavier rockers. They will be bacstroking to Cuba

[@atrox779]

Amazing video, Great job.

[@nickgraupman8457]

The quality, was good for its time

[@WELLINGTON20]

No it wasn’t you dumbass

Flooting Vlave at start at 3:04

Barely and question would be at what rpm was engine vs what spring was created ... I can bet that this spring was operated way higher than manufacture recommended.... theses likkle infos are very important. Likely this was a test by manufactory to know the point of float ... result valve float at 8000 rpm we will limit engine to 6500rpm. ... so no need to rush sn upgrade with our minimal increase in rpm

[@cliffwright9842]

these are mock up situations, would the harmonics be different in a complete running engine?

[@tomasnokechtesledger1786]

Blowby by valve guides would straighten it up a little valve woble? Combustion Chamber turbulence at tulips could worsen it up ... That's the only difference I could envision.

[@mikeforce1776]

Thats not valve float, that's spring surge.

[@BrosB4Pros]

This is a fucking horror movie.

[@mangopog9814]

I see idiots do this all the time with 200K cars I shake my head and say IDIOT more money than sense.

[@bonante2004]

its valve float

[@sprydo7]

If this could be a GSR head,...how much CFM are you working with? So an intake ported B16 should flow approximately @ 235cfm,..that depends upon cam profile as well. On Honda engines it takes 2.5 cfm's to make 1hp.

[@TheJesicamiguel]

so how can you fix that?

[@MossPalone]

Stiffer spring but in the cost of increasing power required to open the valve

[@justw4lkbesideme]

Jude Lau how about replacing new spring regularly, instead using stiffer spring?

[@dailydoseofcancer5517]

Flex tape

Dual valve springs

[@randellgribben9772]

use ...conical valve spring... google it... much better than duel or tripple valve spring set up

[@guygaric940]

it was so fast it fucked up the camera...my eyes hurt now...still an awesome vid
