Check out the Wagon on the Hub Dyno - 4200hp at the Wheel!! World's Most Powerful SMX Wagon! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-LnrZdrp77Cs.html
I was wondering the difference between SMX heads that are based on a DRCE BBC compared to the new BBC RSX that makes 1000 HP N/A. If it is possible, you could build a motor with a Brodix HIP block or the new BBR (3500 HP +) for the street.
Steve, you didn’t have to show the little flub up, but you did! I know people who don’t show the real world of shop life. You seem to be happiest, showing that you are indeed human and make errors and fix it before it ever sees the customer! Too much respect for me to quantify! Love you guys!
I dont think there's any optimizing one. Nothing about it is designed to perform well NA. It's literally designed to be run boosted. Just like an engine designed to be run NA doesn't run well with boost. You'd have to change the cam, the heads, the compression ratio, damn near everything
The fact that you show the good with the bad is respectable! You didn’t have to show that at the end at all. But you did out of full disclosure. Keep up the great work.
Not gonna lie, that 900+ HP NA is quite an achievement regardless if it's purpose built to run turbos. The look on Dewey's face with his ears pulled back had us rolling! Could you touch on the fundamental differences in camshafts - NA V. Turbo V. Blower (screw, pro charger, roots) in a future video? Not to touch on cam specs of course as that's a touchy subject but overall how they differ. Thanks again for putting out some great videos and enjoy the PRI Show. We'd love to do it but work precludes the trip as usual.
IMHO as well shown via Holdner there is no "turbo" cam that works better for turbos when it comes to power. The difference is you can make SHITLOADS of power via boost and don't need cams to accomplish this in the same regard, so for driveability and "idle" ability you can have wider LSA and a little less aggressive profiles that hurt power NA but since his engines can take massive boost and HP - when yuo want more power you just dial it in via boost.
@@HPRaceDevelopment Never heard of you. Can you put a numerical value to "SHITLOADS" as we're unfamiliar with that value and can't seem to locate it on any metric related to HP or torque.
Sure. We build some of the fastest NA motors you money buy per CC or CI. In the range of 240 hp per liter, and they hold together for a time period that would be unheard of in v8's or drag racing under abuse that far exceeds that of drag racing. Steves SMX here makes 88 HP per liter. It's quite low in comparison. Shitloads of power would be 5000-5500 under boost - about what steve says he makes. If steve put his effort to this motor for NA purposes - it would have to be completely redesigned with lighter parts, smaller rod and main bearing widths and diameters, optimized oiling that delivers the minimal amount of oil necessary to keeps parts alive NA, more compression, more aggressive lobes with more lift and duration, more overlap,more compression - and in reality far better cylinder heads that flow more per valve size. If he did so to the level of a unrestricted nascar engine, it would make 175ish HP per liter, or more than double what he makes now. That would be around a 2100 hp NA version of this engine. I'd say 5500 HP is a "SHITLOAD" in comparison - but I guess you dont understand any of that...and have to make digs at someone who probably could help steve with a thing or two... @@strykerentllc
@@HPRaceDevelopment Never heard of you. Exactly how many world records do your unheard of engines hold in any sanctioned class? TO be fair, Steve is doing just fine without your throwing shade his way and yet here you are. Lastly, your writing style indicates you're young as mature adults don't mimic pigeons - fly in, sh*t all over the place and then fly off. Etiquette eludes you, kid.
He’ll never tell you about the camshafts, he designs and makes them himself and he’s said before he’ll never tell anyone what the specs are because if he did then why would people come to him for his specialty. Hell tell you literally anything else all the way down to the bearing clearances but never the cam
I would have loved to have seen Steve’s face in real time when he pulled the header and noticed that an entire machining step was missed ..lol I bought a set AFR220’s and one of them came with a broken tap in a valve over hole but a SMX head is a whole nother level.
You guys have the best “ Dad n Lad “ relationship ever, you play with 5 axis cnc’s, you machine solid billet aluminium, you build and race stupidly fast cars. Oh an you have the best dog ever, more Dewey content would be appreciated 🥰
Thanks Steve love to see with your boy I am battling with alcoholism in my life his Grampa bought him a 85 corvette he is 14 iam going into treatment. You inspire me in so many ways I met you in Detroit and your wife I dream of helping him build a cool car I always had old school muscle cars 67 Cam 67 Chevelle conv 2 69 Chevelles ss thanks for sharing GODSPEED 😂
Steve and bud, as a mechanic, i appricate the engineering that you put into your work to make it serviceable. It goes unnoticed far too often for the "next big power gain" to any given engine but relibility goes out the window. A real racer knows longevity is the real game and you design your shit just for that. You are the best engine builder for the long haul and thank you for giving us a spec of your knowledge and helping us understand the true dynamics of what it takes to do what you guys do.
Im liking the Dad Son thing yous have. I just became a Grand Dad for the first this year, and its so good to see Steve and Kyle putting up with each other so well still ! LOL . Yea na yous are cool. Cheers from New Zealand 🇳🇿
Always a great video went the Morris Family are together working and Educating the rest of us. Thanks again Professor Morris and Kyle keep up the Amazing Work. You guys Rock !!!!!
No joke about not running the same w/o boost. I put your cam/rotating assy into an aluminum Brodix block, set up for a ProCharger. Wanted to get it running while I was waiting for the head unit to come back from being serviced. That motor was so unbelievably lazy and sluggish, I swore I degreed the cam wrong, set the timing wrong, something….triple checked everything. Got the head unit back, installed it, and it revved to the moon. I wouldn’t have believed the difference between N/A and boost on the same motor if I didn’t experience it first hand.
It is kinda funny to hear, that close to 1000hp and 800ft/lbs is just NA. Not supposed to run NA. Here I am happy with 300HP and 280ft/lbs at the crank. The power you can build is mind blowing.
I don’t know any other engine builders that own their mistakes and then shares it to the world! Quite admirable! Even the best make a mistake now and then!
That sucked 😮 glad yous caught it before it caused trouble, thanks for sharing, all the best to yous and your loved ones, and puppy dog I have a Red Nosed American Staffordshire their gorgeous,
wicked vid as usual, love it, keep it coming. as a matter of interest, what sort of static compression is this motor setup with to run happily on pump gas ?
“Lash increases as engine temperature goes up” Because different materials expand at different rates as they are heated, you have to take into account your engine's construction when estimating how the lash will change as the engine approaches operating temperature. For an engine with cast-iron heads and steel valves, you can expect the lash to tighten up a couple of thousandths of an inch as it heats up-so for the cold lash you would set the valve lash a couple thousandths larger than the cam manufacturer's recommended hot lash setting. If the engine has aluminum heads with a cast-iron block and standard steel valves you can expect lash to loosen up approximately 0.006. If you are running aluminum heads with an iron block and valves with narrow 6mm stems you can expect the lash to loosen up 0.010 to 0.012. And finally, if you are running an all aluminum race engine, the lash can loosen up by as much as 0.015.
Just over 1.8 horsepower per cube. If that number was achieved on pump gas, it would be at the top of what's possible for an N/A pump gas two valve per cylinder engine. Would like to see Steve run one N/A on pump gas. I would guess an N/A optimized version of the SMX on methanol or race gas would end up around 2.5 horsepower per cube.
I want to hear a N/A built engine. high compression, high rpm, proper cam… (can’t say big cam or sloppy cam because that’s not how it works to make power). Turbo, NO2 and N/A engines are built differently depending on fuel.
Hello Kyle and Steve, so if you don’t mind saying what do you set the static Comp to ?, you said Low comp so how low is it , I have an idea what it is but would like to here from you . Thank You for the video and hope all is well 👍🏽.
This is why it is a "custom built" engine - all the knowledge and testing of previous engine combos results in more learning of how to improve on what you have previously built. Attention to EVERY DETAIL hence the finding of the missing O rings. Welcome to the Steve, Kyle and school of engines.
I wonder if you dyno a engine with turbos, with a turbo spec cam and then swapped the turbo cam out for a max effort N/A cam which one would perform better on the dyno? I’m thinking it make more with the N/A cam. 😊
Thought you don't check lash inline with the rollers. Always go across the rollers to get true measurement. Due to rollers spinning giving a false reading?
Excellent work! I love the dedication and time you put into each build. But about your new Tom Bailey CNC, I hope this is not true. That Many of those parts are not off-the-shelf and might take 3-5 months to get. Repair
I'm anxious to see Steve and Tom or someone build a car with the drag and drive removed. A a ragged beast of a trailer queen that is a maximum effort in No Prep or Pro stock!!
Steve, you have to have some scrap aluminum around to make a dual 4500 plate for the top of your intake 😜😜😜😜! There would be nothing cooler to see one on the dyno being broken in with a set of dominator carbs 👍🏻👍🏻👍🏻👍🏻, well, firing it back up on the dyno with a head off, may top the carbs 😜😜😜😜! I know, in your spare time 😝😝😝😝! 1.8 per cube N/A with a basic startup tune isn’t bad at all! I haven’t seen much more than 2hp per cube for a boosted applications running higher compression, huge cams, spending time tuning & they don’t live long whatsoever once boosted! They definitely would not live driving on the streets!
