EL MERO MERO HEADER BUILD

Follow along as we try and help El Mero Mero keep her wheels on the ground a little more. Craig Sullivan’s 49 mercury ProMod built by Larry Jeffers has a little bit of an issue carrying the front end. We’re going to see if we can help keep the front and down in this car hauling ass like it’s been doing!!!

Man if i could spend a day exploring the massive amount of knowledge u contain. Rob you are a rare breed, love ur videos i learn something everytime.

[@JMillerJr76]

That car if Craig’s is by far the sweetest looking promod EVER.

[@brianholcomb6499]

Another great video! They say if you can't make something work, talk to a nitro guy 😂😂😂😂! This may sound really stupid, Because most builders do headers similar & I know the pipes are tight together, But wouldn't it be better to put the pipe supports under the pipes & maybe run a rod or a strap in between each for the connection? Basically so your holding the weight from the bottom, instead of pulling on the top of the thin pipe? I'm probably overlooking the reason why they don't! I'm use to collector headers & turbo piping. Not Zoomies. I do understand the lay back & angles, using all the exhaust pressure to help the car! It looks like what you did with the new pipes, really helped! That time slip is awesome, running within 1 hundredth of Stevie, who has every state of the art car, parts, & equipment, is just badass! Thanks again Mr. Rob!

[@craigstrickland1572]

You make it look easy. Your attention to detail...you don't get paid enough I bet. Love the Merc and that Nomad wagon. Hope your wrist feels better.

[@mikeznel6048]

Nice job! Just like the chassis job you did with the thicker tubing and the brackets that go around it so the fuel tank doesn't bind. Great job. What a dream job!

[@FloridaManRacingChannel]

Awesome Build ! Saw it in person at The World Street Nationals in Orlando, truly a work of art. You can tell Craig is very proud of the Merc - great guy too.

[@elijahrobinson2362]

I know relatively little about mechanics, but my first thought was to change the exit angle of the headers. Point them upwards to change the force leaving them. Nice to see physics in action.

[@bcbloc02]

Awesome that small change made that big a difference.

[@randalljames1]

We had a couple sets of headers for the fuel car..(decades ahead of any rules on angles) and found out just how big a difference it made on down force.. When dressed as a "AA/FA" after we went with laid back zoomies 50's to 40s? I had to add a couple degrees to the front canard and still keep the wheels planted.. Down force was no secret.. guess it just took time to turn it into an issue with NHRA.... Good looking ProMod... I think I would rather play Promod than fuel....

[@paulboone44444]

Not many left like you bro... Awesome education as usual.... thank you for another wonderful video

[@andyb9767]

I really enjoyed that Rob thanks

[@davidteixiera8398]

Learning something new every day thanks for the knowledge my man.👍🙏

[@joeblock62]

Under rated channel!

[@DSRE535]

You are a true Professional, I wish I could borrow your expertise building the headers for my Pontiac! Amazing work!

[@carlhanna8429]

That car really is one of my favorites 👍👍

[@TheMrMused]

Great to see you back, Rob! Hope the wrist is recovering well.

[@kencapps586]

Using the angle as thrust worked well for Jimmy Prock when he tuned for DSR...didn't take long for NHRA to implement rule changes. Also noticed that was Jay Cox instead of Stevie Jackson in the right lane. Great content, thanks for sharing.

[@dakotaautosales9673]

He didn't say it was Stevie Fast in the other lane he said that his boy gave it away to Stevie Fast in the next round

[@hankschrader149]

Rob those headers are a work of art! Unbelievable man! 🤩 you know when I do projects I always like to measure once and cut 6 or 7 times and I still come up short! 😂

[@bogthing1]

That's a thing of beauty.

[@billclark5943]

Good to see you posting again Rob. We missed ya

[@captlucky2320]

Definitely the coolest promod out now

[@vinshanestrickland4179]

That should keep it down looks good great work man I really miss my uncles machine shop

[@lorenmorelli9249]

Nice Vid.. Excellent ability. I had partial wrist fusion surgery four years ago.. Worked out better than I expected..

[@DJ-yp4kc]

I heard that years ago about how Headers cause Down force.....GREAT Job! A+

[@robertprice2108]

That is one cool car for sure Rob. I took some pictures of it over in Orlando. I walked up in Craig's pits an took a close look at his car an man that thing is a work of art. Thanks for sharing. Stay safe an God bless.

[@ncpromoder]

Great Video. Very informative

[@gnmatsu]

More cool stuff. Yeah! Thanks for the fun stuff. And educational.

[@TomChame]

Very neat, thanks. Good to see you back.

[@richardlincoln8438]

Thanks for sharing.

[@garymckinziejr7194]

Thanks again for the great content. Hope you heal up soon.

[@tntagridiesel7732]

Always look forward to your videos Rob. Keep up the good work and have a safe holiday season.

[@johnalwine3159]

Great job Rob!!!

[@leyderness3553]

Great seeing another video, missed them for a while. Merry Christmas & Happy Holidays, be safe!

[@jerrellkull5347]

Awesome job Rob!

[@billmiller7138]

Amazing the thrust out of the exhaust. Nice pipes! Thanks for explaining how you fixtured it up.

[@davelowets]

Beautiful, Bad-ass headers... 👍

[@edw102472]

Gosh I love your videos, awesome work you did on the coolest pro mod in the country.

[@vehdynam]

Beautiful pro mod , and equal quality in the header build. Much appreciated video.

[@scotttipps8155]

Righteous and kick ass man. As usual top notch quality and engineering. You never cease to amaze me bud!!!!!!!!

[@hankschrader149]

Ikr?!

[@JJRrcracingfoam]

They work great new numbers 💪💪✌️

[@danielsmith-ze3wy]

Thanks for video

[@Haaspeed]

Great video. I like how u mention how much time goes into welding stainless exhausts. Most ppl dont get how long it takes. Super trick support brackets (i may borrow that idea for the imports i do) Thanks 👌🏽👌🏽

[@elliottmaher2365]

Awesome video, as usual! I love the tech explanations! Any idea how or if exhaust exit angles affect lower powered cars? I imagine it would be a game of diminishing returns, but I’m curious if anyone has experience with when it stops making any difference.

[@jamesbarisitz4794]

Science. Crazy impressive results for a single change approach. The grin on his face when the snout kept to the scent on the ground was likely ear to ear.

[@josephplatania5593]

Time time and more money. Very nice job. That car is nasty !

[@Scofflaw_k10]

Great job, and for what it’s worth that staggered setup looks mean!

[@dezertraider]

GENIUS ROB!,,,,WOW,,,,,CAN YOU USE A PIPE BENDER AFTER YOU HAD ALL ANGLES? MERRY CHRISTMAS,,,IF I DON'T SEE YOU..STAY AWESOME

[@sammygonzalez7627]

Rob i believe in that last pass, orange camaro was actually Jay Cox...if that's what you was referring to

[@erichuff2538]

I know Craig he is a cool dude. 😎

[@808vws8]

Does Craigs merc have a very expensive paint job on it or a very detailed wrap?? Either way the car’s gorgeous&very unique...I wish Promod had more diversity instead of 80% new/old Camaro’s. Luv your video’s as always! Much luv,respect&Aloha from Hawaii brahda🤙🏽

[@robwendland]

Wrap for the win!

[@vinshanestrickland4179]

I found the glass clear cup for my tig and have not looked back try them

[@toddtremayne9699]

What if you do offset headers ?

[@timothymilam732]

You know I am at a loss as to why more racers don't take advantage of the free thrust provided by the exhaust off the engine. Especially the ones with forced induction, which I suppose is everyone nowadays. It should be obvious to anyone with half a spoon of common sense, and mechanical ability to see that. If anyone has ever been around the cars when they're rolling on the throttle, you can feel the air pressure before it even hits you. Are watched a drag race at night, and watched the exhaust blazing out of the pipes, are better yet. Been to a chassis dyno session where the pipes are shooting either straight up, or straight out the side. Because everything around the exhaust if it's not tied down blows away violently. If it can blow the insulation off the bottom of the metal roof 12 to 20 feet above it. Then what more evidence does it take to prove to these people to use it to their advantage. Like a turbo makes free power, so does the exhaust leaving the turbine at the speed of sound. Appreciate your sharing your knowledge with folks, not many have enough confidence in themselves to do that, because they're afraid someone will use it to beat them. All your doing is making it more fun and competitive in my mind.

[@sr20ser.]

Why no back purge?

[@stephanied143]

Do you always have good ideas

[@BustedWalletGarage]

Damn dude. It’s been a rough month.

[@captlucky2320]

What was the tool on the string you was using on the end of the pipes

[@elliottmaher2365]

It’s called a plumb bob.

[@jiveturkey9993]

Does mero mero have an old school airbrush paint job? Or is that a wrap?

[@robwendland]

Wrap

[@vinshanestrickland4179]

Its funny how people don't realize the pressure coming out of the headers and how you can use it to load the chassis

[@vinshanestrickland4179]

[@9rjharper]

That’s not a different radius. All of those bends have the same radius. I’m guessing 6” but could be off. They have a different degree of bend.

[@9rjharper]

Nice work though.

It is not pronounced the way you see it. It is pronounced El medo medo
