We have problems when tuning engines in our jetboats with false knock. Especially in aluminum hulls. I use the Link ECU knock light that learnes the engine noise and only shows actual knock. Awesome bit of tuning kit.
2587 hp from a 903ci engine with 93 octane... well that's not your typicall toyota camry engine output 😄Great job Steve, Kyle, and all the crew, finally got that beast doing what it supossed to💪
I love watching this channel. Steves knowledge and experience coupled with his child like glee at learning new things and achieving his goals is a joy to watch. Plus the close family feel, really makes this channel stand out. Love it ❤
I’m lucky enough to still have my Pop above ground. I stay in touch as much as I can and we always end up talking about what the next move in one of the cars should be. A round win or even a stumble removed is cause for rejoice.
@@simkinsfrank4169 I lost my dad 13 years ago, he was a mechanic and had a lot to teach me. Unfortunately I didn't have to drive to learn when I was young, and he didn't make it long enough for me to finally want to learn. I still miss him every day but I'm grateful for the time that I had with him ♥️
Congrats!!! Another milestone achieved! Would love to see some footage of the boat running wot on the water. Now, I'm gonna do something I've never done, get an entry into the Blazer giveaway... I'd LOVE that puppy and I could retire mine. Then my wife & I could join our son with his Camaro on a few drag & drives.
by profiling my guess is there big-wave surfing and skiing/board-competition, and why the 1k HP engine yes i did try surf and like it but i sucked and boy-scouting badges those were one's i couldn't earn but tried, sailing/wind and fishing was more my things
This is probably the most interesting video I've seen on your channel. It makes it very clear why you can't really set up knock sensing without a dyno. It was fascinating to see what's involved in getting the system to sense real knock, but not other, normal engine noise with a dyno, and how you set it up to remove timing when knock is detected, then how long it takes to put that timing back afterwards, etc. Thanks,
Not so long ago I asked on a PFI Video about tuners using the knock sensor for engine protection, 2500+ BHP and almost 2200Lb ft is just mental, awesome results for all that work, I wish I could enter the give away but you don`t allow us in the UK lol
This has to be one of the best videos of late on you tube. The edit and audio was better than hollyweird has done in a long time. And the slide show at the end was timeless. Thanks for this channel....😊
Hell yeah!!!!! 🤘 If your channel doesn’t teach people to go for life, I don’t know what will, thank you for everything you do, post and share with all of us !!!
I always find this channel extremely interesting! I am not an LS guy at all, but 30 years ago I worked on a top running Top Alcohol Funnycar team. In 1993 we put a 554ci(1" stroker) KB with a big Whipple doghouse supercharger on it & after 23 dyno runs at Billy William's shop it put out over 2600hp/1800tq. And now that is easily exceeded with 93 octane and WAY bigger cubes, absolutely incredible!!!
great info most people dont know about knock and load . its been my experience as well in the oem its rarely at peak boost dose detonation occurs its generally at peak torque for us usually in the 2000rpm range
Don't jinks yourself brother, I wouldn't claim it is done until it's in his possession and I stopped having nightmares 😂 that was a crazy build and definitely a learning experience, congratulations
You can use the individual cylinder trim function to advance the spark one cylinder at a time. You also need to use an oscilloscope to analyze the knock frequency of the engine. Once you determine the knock frequency range of the engine you can select the appropriate knock sensor for this engine. Also knock frequency varies from one cylinder to another. Use the individual cylinder trim to optimize the sensitivity of the knock detection system. Advance the spark in one cylinder only until you get knock in that cylinder, then determine its individual knock frequency. Make sure the knock sensor has a wide enough frequency range to accommodate all cylinders. Sometimes you will need multiple knock sensors in different locations on the engine to detect knock in each cylinder reliably. With crank position information the ECU can determine which cylinder is experiencing the knock and reduce the spark advance only for that cylinder. The more you reduce the spark advance, the hotter the exhaust temp, and the hotter the valves. Also, a leaner cylinder will run hotter and thus be more likely to knock. If you balance the fuel enrichment and spark advance reduction in concert you can optimize the knock response. For example, with individual cylinder EGT information, you can determine how both spark advance reduction and fuel enrichment affect EGT. This level of data granularity will enable the ECU to optimize engine performance with temperature safety maintained across a wide variety of operating conditions and fuel quality. Hope you find this information beneficial!
Could some of the random pings above 50% be from the flywheel hitting starter pinion you mentioned?Also that power with a limited cam,pump gas and rpm limit (because of the jet drive) is awesome.
That’s freaking sweet blower kit, but I’d hate to have to change that belt on the side of the road..lol..think I’d post will feed for belt change sign at the closest restaurant,lol.
I’m going to miss your videos on the big black hemi, you’ve done so many videos on it, it seems like it belongs on your dyno. On the flipside, There has to be that sense of accomplishment… I liked all the info the Holley knock, does fuel tech have anything like that? I’m going to install fuel tech on my vehicle and thought it would be nice to be able to detect detonation. Thank you for your videos!
Years ago we would use a thicker head gasket so we could use more ignition lead. Combustion chamber volume and single or dual plugs all make a difference in how much lead you could use without detonating. Type of fuel is also a major factor, gas , alcohol, and nitro all have different burn rates.
Wow, Mr. Morris! All this time, I thought the BBH was going in the jet ski thing you showed a video or so ago. I was horrified just thinking about what freaking yokel would make something like that, hahaha.😅
Too cool man you are a helluva tuner getting getting knock feedback dialed in on that monster on piss gas. Been tuning with KS since 2000 on OEM ecus. Always wondered if holley and fuel tech has KS feedback. I actually prefer it but I know a lot of people Don t care to deal with them.
Knock frequencies are different for all engines and is actually based on bore diameter kinda like a tuning fork. I tune alot of cars on road and always use my KnockLink headphones. Is a whole different story on the road alot of noise. In South Afirca we have locally made EFI systems and none of them have good knock control so we make extra sure we are safe. If You have a little bit of knock at say 3500rpm at like 27° timing by the time You at 4500rpm it won't knock anymore at te same timing. The higher You rev the more timing it can take because the events are happening faster and that gives more knock resistance. So once I check for knock at lower rpms and find the threshold I know what I can do with timing at higher rpms because it is less knock prone at higher rpm. On a engine like the VW R32 which is a VR6 engine You use 2 knock sensors. One on the front and 1 on the back and You always find that the rear 3 cylinders is more knock sensitive. The Plex V2 is what I believe to be the gold standard of a knock monitor for tuning.
As a diesel tech, I hear "nox" whenever someone says "knock" and that confuses the crap out of me every time... Congrats on the win. I've had some doozies with electrical diag before, one running about 36ish hours and that feeling of finally getting it is pretty amazing.
I'm a tuner and I tune stock base Ecm and Pcms but knock sensors is a must , especially buying from gas pumps. But good thing with factory is you have two fuel tables low octane and high octane timing table, depending on how much knock pcm detects it will use the table necessary. Don't ever trust what you get out of a gas pump. GOD BLESS
So a cool story…. Back in the mid 90’s when I was really big into the 4G63 Mitsubishi 2.0 ltr engine stuff. We used to include a LED light next to our boost gauge and tune, boost/timing on C16 race fuel to maximize horsepower. Our only way of tuning OBD 1 ECU’s was a piggy back Super AFC MAF controller. This is awesome stuff!
Good job some times having to much information is a bad thing haha A thought on the spikes running race fuel, maybe it's the starter pinion touching the flywheel. Looks like it could of touched 4 times through the pull
Maybe the knock sensor was picking up the starter-pinion hits as knock? (Sparks = hit, hit = perceived/interpreted knock. It may be worth putting the video side-by-side with the laptop knock-trace to see if they coincide)
Would be interesting to see more of this giant jetski looking boat. Also interested in how these high horsepower centrifugal supercharged engines go in marine applications in regards to sudden engine rpm drops when going over waves/chop. Is it even an issue? All supercharged jetskis combat this with clutches on the drive assemblies that slip with sudden rpm changes. This supercharger being driven off a toothed belt wouldn’t have any allowance to slip.
I know my OEM ecu KS is supposed to only look for it during a certain range of crank degrees. Tons of fake knock can be an issue so code was wrote so that it would only look for it above a certain load level. Helped a lot. Can you also add fuel if the timing Don t reduce the knock enough?
Where do you guys find these women that are engine and car junkies!?!? Seeing those wives video Steve talk through the software and data gave me hope that they do exist. A few videos back Steve's wife was turing wrenches and on sugar momma (could be mistaken on what car it was) when they had to replace the tranny and rear pumpkin after Jackstand spun it loose. F***ing amazing 👏🏻 💯🇺🇲
Would an engine built for boost be appropriate for towing applications if it was appropriately cammed and no boost? Could low levels of boost be used above the torque peak?
Hey steve ...Very good video as usual...lot of infos...and im wondering in your opinion why gas engine dont like knocking but diesel engine mostly run on knocking and can live forever
The burning happens on the way down, not fighting itself like gas knock.The flame speed is lower so it's not hammering. It's burning in the bowl area and not directly torching the piston, and they're built 3x heavier

(couldn't resist. really enjoy all the stuff you do)
LOL- this is brilliant 🤣 👌
with or without welded on counter weights? lol j/k
@@mrk454😂
wasnt there an SMD? with a strange piston skirt separation
@@mrk454 They'll be available on Stage II package
Knock Sensor testing was great in this video. Your methods to figure it out were excellent. Thank you.

Congrats on completing the big black hemi! Its been a journey for sure. Thanks for taking us along.
Good call on the racegas. 👍Of course you can verify if its real knock by checking the spark plug. There will be speckles on it if its knocking enough.
Steve, Learned more than I thought about the knock sensors and your tuning. Appreciate the in depth explanation. Warning Steve is the best!
Great information on this one. Nice to move on from the Hemi. Many thanks.
Don't jinks yourself brother, I wouldn't claim it is done until it's in his possession and I stopped having nightmares 😂 that was a crazy build and definitely a learning experience, congratulations
I'm genuinely happy you've finished this motor. So many learning lessons on this motor haha. Good job Morris team.
Good job ! You have the balls to show the good & not so good .

Sounds soooooo familiar what you are telling.....😁😁😁
Steve, knock sensor listening frequency is generally a function of bore diameter.
Be sure to get Kamil to get video on the water with this thing. It should be bonkers with that kind of power on that itty bitty boat-jet-ski rig. 🤙😳

I'd love to hear Steve comment on some of the different engines he been involved with and what if anything he remembers about those engines.
Im so happy for you lol.. Get that demon out of the shop forever 🤣
1200 horsepower at 4000 rpm - that's displacement right there! What a beast!😎🤘
Glad to see you did it just shows perseverance pays off
Good job some times having to much information is a bad thing haha
A thought on the spikes running race fuel, maybe it's the starter pinion touching the flywheel. Looks like it could of touched 4 times through the pull
You just don't have any quit in you! Awesome job man!
I may have missed it, but did you ultimately loose big $$ on the big black? Learned a few things, but at quite a cost. Glad to see it’s done. 🎉
Great learning. Thanks
yes do a video of it in the BIG jet ski
nice ski boat 2000 torque sounds like alot bet that thing is light and is a handfull
Maybe the knock sensor was picking up the starter-pinion hits as knock? (Sparks = hit, hit = perceived/interpreted knock. It may be worth putting the video side-by-side with the laptop knock-trace to see if they coincide)
I hope it lives as long as it was tough to complete. Congratulations!!
Awesome I'm happy for you all that work
Congrats on cracking the code on the BBH. I could see it in your face that it about took you down!
I can feel the relief through my screen. 😂
Make sure you get video of him riding that crazy machine.

Thumbnail is perfect ....lol ....."son we did it we defeated the BBH"
I have found knock sensor base lines tend to follow cylinder pressure.
congratulations on overcoming the battle
I think the hemi project is super cool. Totally unique and badass! Seems like a waste to put it in a jet ski...
Hey steve ...Very good video as usual...lot of infos...and im wondering in your opinion why gas engine dont like knocking but diesel engine mostly run on knocking and can live forever
The burning happens on the way down, not fighting itself like gas knock.The flame speed is lower so it's not hammering. It's burning in the bowl area and not directly torching the piston, and they're built 3x heavier
thanks first time ive seen knock worked with
After seeing the vehicle this is going in im appalled lmao still a cool engine
I'm sure you slept well that night. Congrats on another great job. We all learned from that hemi. How many pulls did you end up making on it?
Yeah id put about 20-25% c16 in it, maybe run av100 no lead. Its not a plane, but it still flies!✌️
