The most comprehensive, detailed, and informative tuning/dyno presentations ever compiled. Appreciate the continued videos and of course no video is complete without Dewey making a casual or deliberate cameo. Cheers!
Couldn't have said it any better! Pretty sure if you looked up the definition of customer service it's gonna have a picture of Steve!🤣
Tim Nelson is the best
@@GHBTPUSY Never heard of her.
@@GHBTPUSYthere’s always one
But still incompetent enough to let the supercharger pull hot air straight from the headers 🤦🏻♂️
Spy the AvE sticker! Haha.
Thanks again Professor Morris for yet another great lesson 😊 your passion for teaching is Awesome love the longer Video !!! Keep up the Amazing Lessons!!!!
Great instructoral video for beginners. I've always preferred carburetors. They are smarter than what people give them credit for. If running boost, they act like intercoolers. I'd like the spec's ondy engine tho. Great video as usual.
Take his advice as gold, and these engines will survive years at this level. I've been following him for decades, and I've built a similar setup to this at my home because of his builds Ive read about as a child. I have a 565 cubic inch big block Chevy with an F-1X Procharger that I street drive with the same 77/58 tooth pulley combo that he tried in this video with my timing locked at 30. I also have a 46 tooth blower pulley if Im able to use more. I haven't pulled my engine in 8 years. I appreciate the lessons he shares with us, and I'm thankful to enjoy the rewards of the knowledge that hes always shared with us for free. Expect brutal power. Good stuff
“Who cares, it’s part throttle”. Words to live by right there.
Ahhhh, the mantra when running Hilborns 👍🏼
@@lt1nut a man that "knows"..your post says it all lol
The HP numbers on that engine climb faster than the National Debt Meter.
All my ProSystems Carburetors from Patrick come dead on. We have dyno proven a few times that the jetting out of the box is spot on. Not a better carb or guy out there on the market.
Tossed one our 383 with a single carb blower went a full pitch up on the prop and zero bog and never have touched the carb
Most people call those little screws on the metering block "idle mixture screws".
I like the term "idle volume screws" because they control the volume of the emulsified fuel/air mixture from the idle/transition well to the idle port below the throttle blades.
So they control the volume of emulsified fuel/air, not fuel, precisely.
For fun i googled smx engines an found a few people saying its not reliable an is a hit or miss so i had to drop some truth on them lol i told them that steve cares more about his engines in customers car than people know every evnt hes at an hos engines are their i noticed he takes time to check on how they doing or if they need help with a tune they also brought up the viper smx i also brought up tye fact that steve gives a wealth of knowledge an info to anyone i dont have a race car but if i did i would want a Steve Morris engine in caise i know 75% of it was made in house an assembled by hand an care
There’s always going to be negative people. I don’t think there’s nearly as many SMX’s out there as there are people claiming they’re junk.
At the end of the day basically any race engine making that kind of power is going to break stuff and have problems. Even at “only” 2,000hp it’s still easy to break stuff.
I don’t think he’d be still going if they were no good
Of course there great engines look how busy he stays and it’s the same people buying more or doing refresh’s he had his very first engine on here not long ago it was like 22 years old there is gonna be negative people wherever there is success.
Anyone complaining about a race motor not lasting, does not have valid expectations. If they build it to be race enough, it will only run for a few miles. (and endurance could be the only complaint. Im sure every motor is tested.)
Steve is the type of guy who sells things HE wants to be proud to own;
You are paying for your problems to be his problems;
He takes it very seriously.
Anyone making noise is doing just that, making noise.
If Steve built something that failed; I bet he would take it personally, and make it his mission to help his customer.
Steve awesome video as always , i really like those carb tuning tricks for dialing in a performance/ racing carb . Ive got a AED 975cfm Holley that was built by AED for my Shafiroff racing 427sbc
You just need to buy Kyle a car with a carb and make him drive it to work everyday
And make it a quadrajet so he has to work on it more.
would he ever get to work??? 🤣🤣
Oops! Making too much horsepower! 🤣🤣🤣 Just don't hear that very often
Thanks Steve and Kyle, you guy never cease to amaze me with the amount oh hps you guys get out of these engines , just waiting to see more on your sml blocks 😎👍🏻
I prefer carb on my vehicles just so much easier and I don’t have to worry about electrical issues
Is that AvE stickers on the dyno? No dumb here? 😂
Curious what an SMX would make if it was built as a full NA engine big cam,etc
Great video Steve,, you helped me on my SBC blow through F-1 deal and these videos are tremendous help! Thank u for what u do!!
Got a custom built Pro Systems Dominator a couple years ago. Had fuel leak issues and didn’t want to idle. After taking it apart it was nothing like the supplied build sheet said it was supposed to be. It was basically a stock 1050 spec carb. It didn’t perform any better than my home built carb did so I Sold it at a swapmeet. Bought a custom Braswell carb that works well but no better than my old carb built by me outta Holley/QFT parts from yrs ago. Go figure. Guess I’ll put together my own carbs from now on….
I’m 72 and grew up on carburetors. Once you learn the process, it’s left to the individual circuitry. Holly was my preferred brand.
first engine I turbo'd was a 80 kawasaki kz750 four with the original carbs. I wore the screws out on them by the time I got the jets right! bought special drill bit set, extra jets. even soldering them shut and re drilling
Steve do you envisage a day you will build electric motors for racing?
Cleetus's FF is being threatened with urban growth. Noise mitigation of ICE changes the sport.
I agree. A touch rich on idle is way more responsive. Neutral or a hair lean gives that delayed gag then jumps. Its all within 1 second but that's the difference between competing or going home
If Street Car tad lean is fine.
@@wobblysauce probably. Unless you need to jump in traffic. That gag could be a bad situation. Even a daily. Go a touch rich. My 81 f-100 300 straight 6 is almost right for where I live. All I have to do is flip the breather cover for summer and winter.
@@johnnyshell2839bb ñ
Rich is better to compensate for high ethanol/additive gasoline and/or E85
Adjustoing for a stronger pump shot will clear that right up.
Common problem with low vaccum big overlap cams also or not enough initial timing .
Almost 1400hp on pump gas is pretty damned impressive.
One of your best videos yet! The information was awesome and very detailed.
Stay with the long form vid - always entertaining and informative.
it revs to 5500 and it sounds like its barely trying, yet its putting out 1300hp. Just makes it look so easy to make power. Nice work guys.
Who cares about part throttle? Anyone who daily drives their cars…timing is huge on low rpm and freeway cruise
Idle fuel screw. Back off a half turn makes it richer. Open an idle air screw a half turn, which makes it leaner. You almost had it correct, you correctly called it a fuel screw but started calling it an idle air screw again.
Caution, I learned something, from watching this video!
What is this "part throttle" you speak of ? 😂😂
We need a decibel meter in the dyno room!!!
For someone like me, who has yet to do his FIRST BLOW THRU anything.....that is about three semesters of HOW TO MAKE HORSEPOWER, but be happy when you get less! I met Mr. Morris, when I came out to 131 last year to get a look at the wagon. I told him then, and it still stands...."if I ever got in a position to buy some power like this...I know where I am going". I know it's not an LS...and that's the point! I would leave it just where he ended, and in my MONZA'S, or 78 Malibu, or S-10 Blazer, or my 68 Impala, you couldn't cut the smile off my face.
Quote: power is easy, making it live is the hard part!
Too much horsepower? I didn't know that was possible. Kinda like dividing by zero. :)
You don't necessarily have to have gas in the fuel cell for a procharged race engine to make power, but it helps.
I love the carburetor talk.
IRD carburetor is the best
I went to buy one ..i wish I did now
All the young people and old around me love fuel injection
But I love different wanted to build a engine with IRD carb and a haltech VMS
The other thing with the cards is, watching RUclips on a television, is usually most tv's don't have an option to "display cards". All mobile phones usually do however.
Another banga video. Thanks chaps. 😅
My blow thru turbo liked 11-12:1 afr WOT and 12-13:1 cruising with iron heads but my buddies with aluminum heads was happy with 11:1 cruising and 10 wot.
Soon as i saw that fuel pressure on the graph i said….aint got no gas in it😂😂

Hello wath dou you tink May Cbb 461 can handel in Power.??Have 4bult Block Arp Pin bult.LS7 Crank forged,Manly H-profile rods No no Kina parts..
Can thes Parts handel 20-25 Psi boost??
( The Block and Crank and rods!? ) Tanks Nice Dyno Movies👍
It's funny cause people forget about the differences in their abilities. Carbs have their own benefits and fuel injection have their own benefits. It's really what you prefer, I'm old school and like the FULL RANGE OF POWER that carbs offer. Plus, you don't have to worry about updating a program for it to run properly. Junk in my opinion, constantly needing updates for a car to run properly. Fuel injection has advantages, but it's not for me. (Mechanical fuel injection is superior too.) Well, maybe I would put one in my grandma's minivan, so funny 🤣. Thanks 👍.
,,, I'd have like to have seen the fuel pressure right next to the boost , or the data thereof , for the entire run . Couldn't read the numbers on my screen . Also I suspect that over 12 pounds of boost you might have been relying on those large capacity float bowls .
Awesome video and makes me want one of these Blow Thru Procharged setups even more! As soon as I saw your carb leaking I got flashbacks haha. When I received my carb from them it leaked from every orfice possible. The Needle and seat didn't even have gaskets installed. It made the dyno tech pretty frustrated with me while I tried to fix all of them. Not to mention one of the locating pins for the float bowl on the metering block was completely bent and fell out once the bowls came off as if the pin wasn't seated properly when someone cranked down the float bowl bolts. Contacted Pro systems and all i got was a "Sorry ill let my guys know to be more careful".
Oh F man that sucks. Youd think you spend top dollar for a custom carb and get a teeny bit of support
Keith over at AED gives the best customer support Ive ever experienced. Hands down the best ever!
Real patient guy wants every customers car to be its best. Not used to that still lol
too Funny at 38 Mins this thing is makin Steve Scratch his head on every pull LOL! Men and theyre Machines thanks fer the Smiles and Knowledge on this this Video Mr.Morris
So I've decided to run my ~650hp n/a BBC carb'd, I had it fuel injected(FAST meh), had an engine fire, re-built it myself (first re-build I've done), I want to go holley terminator this time but want to make sure the motor is healthy first so I'm going to toss a slightly small 800cfm carb and a standard HEI distributor on it and run it for a summer and just not push it past 5k rpm: so to get to the point my buddy says, put O2 sensors and an AFR guage in for carb turning (makes sense), do you think its a very good idea or is checking plugs every few drives good enough?
Steve,
havent had time to watch yet so...
On an sbc mechanical pump w/Holley, it would use a max of 7ish lbs fuel pressure or so no?
Would 7 or more lbs boost push back through the needle/seat orings and screw things up
How do you handle that situation? Not really into putting EFI on an old car
Is the answer to build more cubes and limit boost to 6 lbs?
What i find funny is that the oil pressure drops at peak revs and Steve says 'i'm going to add a quarter', i'm a dickhead that has driven the same camry for the last 20 years, but I would expect the oil pressure of that engine to drop slightly at max revs. it's still over 90 P.S.I. That pressure looks perfect to me (who is just a key board warrior). Thanks for the content Mr Morris
Why would you expect the oil pressure to drop at max revs? The pump is spinning faster and the clearance on all the bearings remains the same.
Cavitation, and i'm just starting@@bradley3549
could be relief value venting, might even be the fictional loses in the oil line at such high volumes @@bradley3549
It is running out of oil in the pan to pickup. Under normal conditions, it would be gravity fed into the bottom of the pan more effectively.
Do you actually know that? over 90 PSI, hardly running the bearing dry.......
@@joebloggs2635
Hey Steve, I’m looking to put a ProCharger on my 565 and this is a lot of great information!! Thank you for your experience and help! I will be giving you guys a call within the next couple of days to figure out the right combination for me!
Steve flexing his knowledge on this one. quick question, those idle adjustment screws dont back out in the car with solid mounts/poly mounts? thanks for schooling me in carbs today!
“Who cares, it’s part throttle” finely something I already knew. lol. thank you for all your help
Your opinion on the willys super bowl systems they are using on dirt cars and will they work with forced induction..
Here for the "first" comments
Back in the early 90s i Had a 302 windsor with a blowthru vortech supercharger making 15psi amd it ran like a scalded dog but the only thing that always puzzled me was with a 650dp carb I had to run 99 jets on all 4 corners to keep my stochiometric ratio proper. Weird huh?
Admire your work . I know you weren't concerned with the oil Pressure as RPM increased , I have had 2 similar experiences with 540 big blocks & it was the Milidon Pick up that caused the issue ? .
I got questions. Where do you buy fuel pressure regulator with boost reference?
Cheapest way to make a 1000hp drag engine?
A lot of that will depend on how long you want it to last.
A junkyard 5.3 LS and Chinese turbo can get you 1000hp for really cheap. But, the longer you want it to last the more expensive it’s gonna be.
Perfect video after a long work day!
Love your chanel I am engine guys from my Yong age and I lurn a lot here still tanks for this
Idle mixture adds/removes air AND fuel air bleeds are air as you said. I personally change IFR if screws are out too much ie 2.5 x out.
So it's the idle mixture screw. Not the air screw... Not if it adjusts the fuel level.
(Motorcycles get both. If it's by the bellmouth on the intake side it's idle air open it up to lean the idle. If it's on the engine side it's the mixture screw and will add gas when opened.)
Very strong engine awesome video...keep living the dream ✨️ Merry Christmas to you and your family
plz steve, change the title to how 1200 hp with carb. So more can understand the right way for carb boosting method.. Thanks man
Don't worry Kyle in 20 years when he's old and decrepit you'll get to have your fun with him😂. We'll all be watching😂😂
Thank you for taking the time to do this. It was very informative and entertaining to see what goes into it. Especially on a blow through setup.
What engine is this Steve? Been fighting the valve guide plates breaking on an old school 427 chevy with the big OD pushrods.
Steve, do you know how to make an engine pump smaller that it is....for example make a 377 pump 358..
I am sorry, Steve, but Patrick, that cats carbs aren't any good these days, especially when it comes to blow through and e85. His carbs get sent to other carb builders like IRD and a couple of others more than any other custom built to order carb company. Back in the day they were good, but it's always something with him now days.
Non-Intercooled with pump gas, hmmmmm.
Big fan of blow thru setups because of that tip in response. Makes em nastier.
Merry Christmas to all at Steve Morris engines
I love it when the parts guy drops a spark plug (still in the box) and hands it to you like there's no way it could be broken. 23:00
Did you see the video of gail banks twin turbo supercharged diesel where he slowed down the supercharger and it maid 200 extra horse ,he said it was from parasedic loss ,gess that means heat
It would be great to know the manifold air density with the different pulleys combos, Gale banks has a set up that would be of great help with extra data.
Where were you 10 years ago. You actually take the time to “overexplain” ( which I am accused of all the time , refrigeration tech) to make sure even the weary understand. You sir , are the man!!
Not necessarily ive seen single needleand seat good up to about 1400 hp depend on fuel being ran.i run a blow thru csu carbs and so do all my shop car and never had a problem didnt see problems till after that bit yet if its tuned right you do get cold chills build up on the intake
@Steve Morris Engines how about an open house one day in the spring? I am sure there are several Fans that would love to check out and tour the shop.
- 👍 👍 🔧 qoᒋ ǝɔᴉN Merry Christmas 👀❤🤍💙
top video bud, CARBY/ DIZZY engines for lyfe ;)
I'm sure I missed it but what cubic inch motor is this and compression just curious as you said your running pump gas. Great video nice to see some expert information on a carburetor from you.
These bleeds? Sorry couldn't help myself. I hope someone gets this joke, it is a really good one.
My friends dyno , he installed a gas water tank and pumps hot water through engine pre fire up. He says he get work done faster and less cold start fowling and wash down 😊 i helped him plum it . Bunch or ball valves.
If I was 30 years younger ,i'd be thee applying a job !
A lifetime of knowledge for free!
Whats your opinion on doing the cam 4/7 swap on a big or small block chevy
Couldn't give me one of those. Seen too many PS carbs with issues.
How do you know oil level if you don’t run dip stick???
You count the quarts as you add them. If it's not leaking...the oil is still there.
If its for a street car yes but no race car uses one
Steve teacher of the trades!! What is old is different than New!!
Fun day tuning, the second pulley set, was good, it dropped the mid range torque bump which is good, that area can be the one to hurt bearings, and break other stuff.
Thanks Steve, I learned something today
Great content - thanks Steve, its good to see what scares the minors.. lol
u should try a Progression ignition hei on a motor like that, it is bluethooth to your phone to retard timing in boost
What c.i. is that BB ?
What spark plugs do you use on that set up if you can share 🙏🏻
thanks so much for sharing learn a lot from watching
Have you tried during a Morse test on your Dyno? I.e. dynoing engine full pull, and then pulling off individual plug leads and retesting to see what power drop per individual cylinder? Stock)ish) smallblocks usually make about 6 - 8 % better power on the middle cylinders, than the end ones - especially the rears I'm sure most know why..
Flex/distortion is your answer as to why middle cylinder make more power
Drop the pulley down to 66 or 68 tooth
Don’t you know you’re supposed to keep the smoke inside that’s what makes the stuff work
When he goes to lunch go put a carb on the smx .
