Impressive. Hopefully you're able to eliminate any noise from the pipes vibrating and hitting each other.

 

 

Can't wait to hear the end result

 

Thanks. Once they are all tied together they should be fine. I am a bit worried about header to frame contact as the motor rocks, might need to go with stiffer motor mounts if it becomes an issue.

Yea, the beard damn near got sucked down the throttle body. Need to tie that fucker up before it catches fire when welding.

 

I've had my beard on fire twice...not an experience I care to repeat! Honestly I'm a bit surprised it doesn't happen to welders more often.

Come to that, getting beard hairs caught in a crack or cut on a mask hurts like a bitch, flip it back for a look-see and you've got a bloody chunk of chin dangling at eye level...

Primary tube #3 complete.

And damn! #1 primary at it's shortest route would end up a touch over 40" long. Making the #1 primary the priority, the #5 will suffer the same fate. And looking to the passenger side I fear problems will be worse due to the spark plug angle. I've had plan B on the back burner, time to incorporate it. This will happen no matter how many headaches caused or beers drank pondering possibilities.

I'm always amazed at what can be done with a welder in the hands of an artist. I consider good welding artistry. It's really a beautiful thing. The sound is amazing too :)

 

Agreed. I'm fascinated by this.

 

Props to Tinman as well for trying this with a specific tube diameter...I wonder if a slightly smaller primary tube diameter would make packaging a bit easier without sacrificing on performance or SOUND. I'm reminded of the "Engine Masters" episode on YT where they bashed the absolute garbage out of some Hooker headers on a SBC and dyno'ed the results - barely noticable decrease in power.

Will a slight difference in length really effect sound that much?

 

And man- I have to tell you the SOUND is worth the effort. WOW!

 

I was looking at a 3" difference. Might not make a difference in sound and maybe negligible in performance but neither am I willing to compromise to that extent.

 

After hearing the difference from the unequal length and the equal length headers I built for the 3800 V6 in the FC, I'm thinking there is quite a bit to keeping the tubes equal. It went from sounding good for a 90 degree V6 to sounding quite good for any engine let alone one of the worst sounding configurations known to modern motoring that is the 90 degree V6.

 

Agreed, all of the headaches are worth it for the music possibly at hand.

When you're done, would you think there could be a market for these done in titanium?

 

Possibly, but not for me. I hate making things more than once. The first challenge and execution are absolute bliss, anything after that is the ultimate in boredom. I don't even dip my french fries in ketchup equally each time, I need a new flavor mixture in each bite.

Thanks again for all the compliments gents.

 

Plan B in effect, Steve at Tubular Techniques got these bent and flared for me,

4 at 20 degrees and 4 at 7 degrees... and 2 more of each because i know I'll screw some up along the way.

 

Going with 4 into 1 flat collectors. I looked briefly but not too hard for off the shelf flat collectors but came up with nada. Probably because I did not look to hard, wanted to make them myself because at 40 I have almost a full head of hair and thought is was time to pull some out in frustration.

You have me literally considering cutting the firewall out of my RX7, and staying NA just to make this happen.

 

In theory-you could hang a turbo off the end of the collectors and it would still slund pretty expotic? Maybe 180 FORWARD to an 80mm since there is so much room up front?

Or can also go with a pro charger instead ?? I couldn't imagine the sound though NA with these at 8000 plus rpm

Not much of an exciting update. Just the start of the jig for the 4 into 1 flat merge collectors.

 

Some 1 3/4" round 6061 bar stock sliced, faced, drilled, and tapped on my work's metal lathe.

The pieces bent and expanded by Tubular Techniques before they are cut to merge.

And the beginning of the layout for the jig for cutting the pieces.

Hopefully some good progress to come this weekend...

that's what I was thinking......I mean look at how his toes point outwards. That's never good. :D

 

 

a video of this thing when it's done is going to be awesome but if there's anyway possible I want to hear it in person.
