That is a lot of tubing... generally the tubes are arranged in the firing order to rotate around the merge collectors. This ensures that each cylinder that fire generates the most negative pressure wave to the next cylinder that fires. I designed NASCAR and F1 headers for Hendricks Motorsports and Toyota.
Agreed! This version of the headers is meant to explore what this will sound and perform like while being shaped symmetrically. I think a "revolver" style like you've mentioned would be the next version to have fun designing and making.
I'll occasionally go scouring CZcams for 'x'-1 header projects because I'm addicted to the sound, so the timing of your upload was very convenient. What a cool project and insight into the model/design process. Thanks for sharing! Will be checking back in as it comes along.
I can't wait to hear it! You could tuck in a Helmholtz resonator under the merge if the frequency amplification isn't to you liking. I am going to be using the Heatshield Products 800102 direct contact heavy duty felt to protect items from the headers.
I love this so far, your channel has a lot of potential! Good luck with this build, looking forward to seeing it come together! I've got this as a long term goal as well, building a midlana type locost "evo" one day
Another thing you could've done with this is to do a Celeritech style setup where you go 8-4-1. Been reading around that a lot of 8-1 seem to lose power over 4-1 and "normal" tri-y setups regardless of crossover type used. Several guys have reported gains of 40+ HP when switching from 8-1 to normal headers tuned for the engine... I think it's down to the collector not being ideal for that many damn runners merging into one section, but regardless, I still want to see someone try an 8-4-1 where the 8-4 part pairs cylinders that fire 360-degrees apart (like a 4-2-1 4-cyl header), then merges the 4 resultant secondaries into a normal (but obviously oversized) 4-1 merge collector, keeping a sequential/rotary style firing order.
Definitely tall, it won't be the tallest feature in the car but it's close. I've got some ideas to work it in but worse case scenario I redesign a set using a smaller radius.
Yep I think that's a good way to put it. It should see a boost of efficiency right around there and above that range the camshaft I got for it should get into its power also.
@@DirtyElbowsGarage It made me think! I'm dreaming up an intake right now and calculating for usable power from 4000-6000, but maybe I'm reconsidering.
@@DirtyElbowsGarage wonder what would happen if you put a big turbo on the end of the collector and ran it into a machined aluminum plenum box, indycar style? Just thinkin out loud.... or is that next episode?
Haha that would be pretty cool. Next episode on the mid engine car we're gonna jump into the design, where it's at, and a bit of the process behind that.
@DirtyElbowsGarage Got caught up on the rest of the series, can't wait to see the chassis! Just thinking out loud again but a roadster or IMSA type prototype would be cool!

Excelent comment! i belive that the sound is different 100%
He would need stepped tubes for the longer length right?

You having less than 2k views on this video is a crime. Your work is pheoniminal.
Thank you! I'm glad it's gotten to where it is!
100 percent!! I hate when great channels don't more noticed.

That's an absolutely wicked header setup. Badass work 😎
This is epic! I loved seeing your design process, especially that sensor feature. Keep it up dude 🤙🏽
Wow! That is a REALLY cool arrangement!!! Props from an exhaust snob
good stuff!
Turned out great! I agree that radius is a bit on the large side. Can't wait to see how it sounds. Nice work! 👍👍
Thank you! And I can't wait either!

This is great . BUT HOW DO YOU PULSE TUNE THE EXHAUST WHEN ALL YOU HAVE DONE IS NOT SET THE HEADER TUBES , PAIRED ACCORDING TO FIRING ORDER .
I hope this sounds like tanner fousts 8 to 1 ls passat

We miss updates on this
Working on the next video now!
No back purging ? They will crack.
I dig the headers but how high is the back of the body going to be? It’s so tall it looks like it’s going into a station wagon
Definitely tall, it won't be the tallest feature in the car but it's close. I've got some ideas to work it in but worse case scenario I redesign a set using a smaller radius.
Wow your back tires are going to have to be so far apart
Love it!
So 3000rpm? Is that the lower end of target power band?
Yep I think that's a good way to put it. It should see a boost of efficiency right around there and above that range the camshaft I got for it should get into its power also.

I may have missed an episode, but what are you planning to drop the engine into?
Hi, making my own custom car from the ground up.

Have you considered 180 degree headers?
I have but I still wanted to try and build this 8 into 1 setup.

That would never fit in a car, please make it more real
