Well, I worked with Burns on the collectors. Getting them to fit where i had room. Nothing was ever discussed on backpressure being an issue. I have yet to measure the backpressure, but i've still got alot of dyno work to do when i can get back to it.

The collectors may not function as they would NA, i don't know for sure. But i can't really see them being a problem. I was actually more interested in them for the slip fit. Help eliminate the potential for header cracks.

Awesome work^10! I'd be interested in one of those dual maf boxes if you ever decide to make 'em.

Simply amazing.

Well after looking at all those pictures, I think I'll print them out and make a book that when you flip through it you can go from mild to wild.

Oh and by the way - here is my favorite picture.

Can I get some of those sweet colored header pipes - but for an NA application?
I was unaware that stainless steel came in yellow, purple and green.

Anyway, completely awesome project and I look forward to the new numbers.

I dont think merge collectors would help really(like a NA setup) but it certainly cant hurt!

Hey Harlen....

I debated making a single turbo kit...and wondered how to get a good visual of how to the run the primaries so that things would clear.... hard to picture/figure something out in your head and then make sure the plugs and stuff will fit.. he he... great idea on the foam tubing.

I have a gasless 110V MIG welder that just won't do the kinda welds i want(i was gonna use mild steel tubing).... i need a TIG... how large is the one you have?

I have a metal chop saw i was using to cut the tubing with... but i think a band saw would do a better job and be cleaner.. what did you use?

Thanks,

The foam tube is part of a kid's toy. They're called toobers and zots, invented by a guy from MIT actually. They have an aluminum wire running down the center so they hold their shape. We used them back in college on the SAE team to make the turbo headers on the racecar

You can find them online at alot of craft and teacher stores.

I use a 180 amp Miller TIG, that's plenty big to do thin wall tube. Other than that, i used a 14" metal chop, a 4" portable bandsaw, a hand-held belt sander, and an assortment of hand files.

Nothing special, but i did use my plasma cutter here and there. Convenient, but not necessary.

I did find an easy way to mark random cuts along the mandrel bends to get nice joints. Use a zip-tie around the tube, tight enough to hold it's shape on the tube, but loose enough to slide along the pipe. Just wiggle the zip-tie along the tube by the long end left over after tightening it. Kinda spin the tie as you move it. It gives you a nice straight edge to mark for the cut, and tracks the bend on the tube pretty well. Made piecing bends together pretty straight forward.

And yes, the bandsaw is much better for making cuts along the bends. Hard to hold for the chop saw.

Good luck with it

Got any details on the TT LT1 that was with you guys at Thunder? I'm interested in the manifolds. Very nice job to whoever did them.

I did those too, what you wanna know about them?

RyanJ

everything! lol.

not just the manifolds.

I talked to you a little bit about them at the Shootout (on the wall by the pits on Sunday). What diameter are the logs and the primaries? I remember you said they were stainless...321 I guess? What's the story on the motor and have you gotten any numbers out of the setup yet(dyno-wise, I already saw it slide down the track )? What are you guys going to do about air inlets? I noticed it just had small screens over the chargers at the track.

Do you have any pictures of it like you do with your car? It's remarkably similar to the setup I've been putting together for the past month. I shot about a minute worth of video of the car and will be posting video and still of it, but it doesn't show much of the cold-side piping.

Thanks

ahhh ok, well i need to get a set... didn't know about the wire in the center but that makes even more sense.

... i'll check the trading post, might be able to find a used TIG for cheap.

And the zip tie thing is genius too.... after cutting some tubing up... i realized putting them together was going to be tricky.... well either that or i am gonna have to get good at filling air up with welds

Thanks for the help Harlen..... now just e-mail me some of your brains, skill and a small miracle and i think i will be alright.. he he

that is some nice work, i hope to copy what you have some day.

i also would buy one of your black boxes for the twin mass air's. i bet you could sell 10 of them today if you had them ready to go.

AMAZING!
