I don’t think iv ever seen a good champion spark plug other than a lawn mower/ wipper snipper spark plug ! NGK all the way

Valve spring temperament time

I am Dave. Wondering if you ever got that Valve train problem solved about the valves opening under too much pressure? I have a degree in hydraulics I was wondering what the cylinder pressure was that the valves were trying to open against

I'd love to know how you made out

Just remember area times pressure equals force

Once you add those sensors. I know the actual cylinder pressure you can mathematically figure out how much pressure the valves are trying to open against

To me it looks like you're just looking at the cam profile looking for valve bounce and such. of course engines going to have different harmonics and pressures when it's running. This is a good way to diagnose any problems up to that point when you do run it

Maybe try cracking the valve slowly off their seats to alleviate some of the pressure before they go fully open. Just a thought that's what I would be looking at the cam profile

hydraulics expert. You're talking about Pascal's law where area times pressure equals force. yes I can believe that the valves are under tremendous pressure to stay open or closed

Will the alum block be able to withstand that kind of punishment or would a billet steel be better? Are engines for sale?

What an honor to be on the inside of this level of power testing/tuning. Please keep it up!

Love the video and info but I would hate to cut a nice set of custom billet valve covers just to make this video ! lol I’m sure that wasn’t a cheap replacement , let alone have to weld them back up and keep using a beat up cover on such a nice engine .. would love to see this video on a turbo ls motor so some of us reg folks can see how much a street strip engine is effected with around .650” lift springs .

Im a machinist. You did an excellent job of explaining everything. I also build big block chevys and those push rods are insane. That is an incredible engine, love everything about it

Is this a dry deck/head engine? Because you pushing water from some where.

Certain engine builder's that have been in business for 50 plus yeats have had big block chevys 500 cubic inch engines on the dyno at 8800 rpm for 8 hours straight with no failure. Not on a spintron!!!

Sorry you folks are behind the curve the have been using 9/16 and 5/8 pushrods on 500 inch engines for over 20 years in prostock racing

I really like the honesty in these videos. I am a bit suprized that the radiator balooned. Are not all of these extreme hp engines dry decked?

What is the displacement of this sweet ass motor?

Very , very impressive.The research being done here is second to none. I am really looking forward to seeing this car on the track. Many thanks.

Get video of the lifter and pushrod. They are the true culprit of valve float.

If you match th path of the happiest cylinder and set the worst cylinders to match them do you get overall equality?

You guys are Freaking awesome. I'm an aero engineer and watching all of this is truly fascinating, really makes me wanna switch fields and work alongside you guys, Definitely keep it up!!!!

what's the air density post compressor? it doesn't look like you use a charge air cooler- wouldn't that help with detonation/knock?

how can you have detonation after the spark event? isn't everything in the cylinder burned after the spark event?

You guys need to team up with the Slo Mo guys and get some high speed video of the compressor, and after the compressor would be cool too to see what the water is doing there, if anything is visible.

Grats! Very interesting journey. Good luck in the future.

Observing Shane and Ben at work is fascinating. Thanks for letting us have such a great view of the tuning shop to watch and learn from two of the best.

This is awesome content, super cool. I'm just spitballing here, why not mix the water with the methanol, say 5% water, and then just add 5% global trim to the fuel table? If 5% isn't enough go to a higher percentage. If the water slows the combustion down add timing. If your primary goal is to defeat pre-ignition, this seems more reliable than dribbling it in front of the turbo. Obviously, you'd be processing water at idle so that's not ideal but you'd get better cylinder-to-cylinder distribution, right? Please convince me otherwise.

Dyno Numbers are cool... Winners circle pictures are ALOT cooler!

Doesnt matter how much HP your car makes, if you cant get it down the track consistently...

So much knowldge and wisdom in one room, fascinating to hear all the real intricate details about tuning!

Red shoes?

jesus christ, are you ever going to take this car to a race? or just burn up motors on the dyno?

It’s so foggy… lol

I think it made 4700hp on dyno😊

It all sounds great but a trip to Fuel Tech would solve all of your mysteries.

Very , very impressive !! My hat is off to all of your team ( I have always believed in water injection ). Many thanks for this video.

yo the spintron is a beast

What brand engine is this ?

You have a great grasp of what is going on as well as being able to explain it in a way that normal people can understand. Kudos.

Boost entered the cooling system and blew the radiator part fn crazy

Looks like a funny car 😀

That sounded so smooth at 9 grand it's scary

Substitute an SMX BLOCK FROM STEVE MORRIS!!!😎

Add some alcohol to the water. It more effectively cools the charge air!!! Use a BANKS POWER SPIN water/alcohol injection nozzle (they work at supersonic injection speed; hence better atomized mist and better cooling!!!)!!!🌊💙💜😎

So interesting watching pros dial in tune and walk that razor love it

These tuning videos are awesome. I wish this was a thing. Most dyno videos are full of tuning and dynos pulls but lack info

Thats pretty interesting to hear about that water injection definitely different

Use o injetor de água, logo após a roda do compressor do turbo assim evita vibrações indesejadas no turbo...

So much information in this video. Big thanks for that!
