Crazy to think I was about to type out that the SMX can live at 4500 HP. And then trying to wrap my head around a car that can street drive at 1100HP and flip a tune and make 4500hp. Absolute crazy world we live in.

[@arbiter1]

its able to do that cause Cleetus has same engine and the intake has a total of 3 injectors per cylinder. 1 injector for pump gas for street driving and idleing, other 2 are for meth/alcohol to for strip runs.

[@kaos33633]

@@arbiter1 oh I know how it works. I follow Steve Morris and am a mechanic. But like ten years ago 500hp was crazy lol it's crazy hand over money and get 4500hp plus. And drive it on the street

[@thetruthspeaker1978]

​@@kaos33633don't you love when you make a statement and someone explains the why's of it with "cause Cleetus has same engine" .. 😂😂😂 I don't think he understands that People have always had the ability to put big ass turbos and multiple injectors on an engine but without modern electronics it was simply a bomb. So that leaves me feeling the same way as you, 500hp was a lot not very long ago..what a crazy world we live in. 👍

[@Ray56z]

@@thetruthspeaker1978 Decades ago when I was street/strip I so wanted to turbo I hunted one down, wanted it on my big cube SBF. I was good with wrenches but smart enough I always had a builder. He shut me down no questions asked after he explained the limits on having one for street and strip-which I needed due to hustling runs off the tracks. If I were 40 years younger today, my smile would be frozen from the top of one ear to the top of the other ear. And I'm actually glad I stayed away from the vids and tech on turbos until a couple of years ago when everything is just about where it's able to go, and pick up the info now. Even back then it wasn't even imaginable what's the norm for big money builders and buyers today-take a 2hp per cube and turn it into a 6.5hp per cube, then back to 2hp and street driven.

In other FT videos I noticed that people wondered why all the race gear being worn, it is just a dyno pull. I suspect there has been a close call with a fire at least once and that is why all the gear, some of these cars are not exactly super easy to get out of really quick.

[@glennverdeyen5685]

Thinking it is "just" a dyno pull is what gets people hurt. At these power levels, anything can happen. Fires, mechanical failures, etc etc. People have been seriously injured and even killed when dyno pulls have gone wrong.

@@andreweberjavorski2231EXACTLY. Beyond the fact running tests with E85 are dangerous enough, this monster is running METHANOL, BABY! Not only will it make you look like a crying wimp (“I’m not crying, you’re crying” joke) but it burns colorlessly and so much of it is being delivered to the engine in one of these pulls if you had a fuel hose failure plus a spark you could have an ugly situation in not many milliseconds. Why do you think F1 outlawed the use of methanol…fires were being started accidentally in the pit and nobody knew it until their skin started boiling!

Awesome project! In all fairness, the stock V10 cast block is a pretty capable platform and while you can get 3K+ HP out of it, longevity certainly becomes a factor. I know Calvo is working on a billet V10 block so that will be interesting to see and with Nth Moto in the high 6's with the V10 platform, I'm hoping to see this car run in the mid 6's if not lower. :)

The problem is they don't last long at 3,000 horsepower like at all... Steve Morris is trying to make the viper block better right now for a different customer and they're trying all kinds of crazy different techniques hopefully it lives a lot longer than normal... But I like the way this guy did it and put one of Steve's actual engines in because he could push it to 4500 if he really wanted to

[@cliff4695]

Steve already has a billet V10 viper engine. This SMX can easily make 4,500hp. Not sure why they didn't just let Steve do the tuning

[@randalltufts3321]

Given the bore size and current geometry on the billet v10 block it comes down to available heads to make it really perform. It only took Steve 2 years to engineer, develop and put into service the SMX heads. Everything takes time to implement, and sure he's gained a whole new perspective on performance with the SMX and the ( SML , More than a year currently) and thats valuable towards new projects like the v10 motor. What it will come down to is being able to say it's a v10 viper billet motor that might get somewhat close to the power output of the SMX but I doubt it'll come anywhere near the performance level of the SMX. But. It will be made more reliable than the old castings. In the end they can say yep, its a v10 viper lol.

[@sepg5084]

The viper would need a straight rear axle to fully utilize 3000+hp. Yes it is a bit doable with a IRS, but it won't be optimal. Plus if they are already chopping up this car like this and putting a V8 on it, then might as well give it a straight axle.

Steve Morris recently dyno'ed one of the SMX engines, it was his old wagon engine, Now raced by Cleetus McFarland in the Mullet Elcamino. it dyno'ed at 1080 I think with no turbos hooked up. the test wasn't specifically to see the numbers, but to check if he got the Bypass on the oil pump working properly before returning back to Cleetus. So your 1k with 3 pounds of boost, is consistent with what the SMX build is capable of. Just so you know, the build in this viper is probably similar (but not sure) to the Tom bailey Sick seconds 2.0 at 540 Cu In (only with i think a procharger), where the one cleetus runs is a 565 cu in setup

[@bobgreene5460]

572 SMX, listen closely during first couple of minutes. Mullet now has the 572 ,The Boost Wagon also the 572

[@crazylarryjr]

@@bobgreene5460, I knew it wasn't the standard 540 like Tom Bailey's, but wasn't sure the exact cu in, and this is with exception of the procharger practically the same as Cleet's. Thank you for the clarification Edit, i was wrong, I assumed supercharger due to the Zoomie look exhause, i realize it's an overly engineered turbo exhaust, not true zoomies

As much as i admire the work and design of these engines, when you take the v10 out of a viper, it's not really a viper anymore. the engine is 65% of what makes the viper the viper. That's the most unique part of the car.

[@willrynes7926]

This is more of a viper than Odoms Gtr being a Gtr. Odom is claiming GTR records when literally the only thing that is authentic Nissan GTR is a roof skin and quarter skins. I like how they talked about adding 2 more cylinders to the SMX because I was already thinking it earlier in the video that it would be awesome to still be a V10 but an SMX. That 3500hp would have been near 4500 and they still have more in it than that. V10 SMX on kill would be over 5k to the wheels. I can’t wait to see this car doing drag and drives.

Would be interesting to see the difference in down force from the zoomies and bull horns !

That used to bother me thinking the zoomies were stronger, till Murder Nova lost a bullhorn and almost wrecked the newer car due to the shift in downforce. Seeing the change in real time (Car literally got up on two wheels) sort of stopped that argument

[@glennverdeyen5685]

I'm really curious what the deal is with these zoomies? Can you enlighten me please? 🙏

[@crazylarryjr]

@@glennverdeyen5685, There is a reason on TF and TA dragsters as well as TF and TA funnycars they turn the pipes up, That is downforce. A TF dragster can generate over 2000 pounds of downforce (more than the dragster weighs) alone, that downforce along with the spoilers fore and aft help plant the 10,000 horsepower these monsters generate. In NPK racing the Nitrous, NA 9rare) and the supercharged cars use the same type of Zoomie headers while the turbo cars use a single pipe coming out the side of the body. Some people (me included) thought the zoomie style being more direct (not through a turbo), would generate more downforce, Like i said i used to think this way, but the test run Murder Nova did where he lost the right side bullhorn (pass side) the downforce from the left side pushed the car so hard it got up on two wheels. meaning there was a lot, maybe not as much as zoomies, but lots of downforce to use. BTW yes the 3-5K (estimated)HP NPK cars won't generate 2k pounds of downforce, but whatever they can can be used very well with a properly designed exhaust.

[@glennverdeyen5685]

@@crazylarryjr Thank you for the quick tour of dragracing exhaust downforce. But other then downforce they don't restict or increase power? And why the zoomies over a bull horn? Is what I'm really after

[@crazylarryjr]

@@glennverdeyen5685, first off zoomies are simple easy to repair and a straight shot, secondly if everything was into a single pipe you have to time them so they don't interfere with each other, two exhaust charges hitting simultaneously. can disrupt the flow, so like with the intake, individual runners is best, the bigger the better in this case, the reason turbo's can't do zoomies, is the turbo is exhause driven the combined force of one side (twin turbo) or both sides (single turbo) drive the power adder. BTW those aren't true zoomies, they are run to 8 pipes, but not a true zoomie
