TT headers

[ka67_72]

Is it worth the extra effort to build equal length turbo headers for a street motor? If so what's a good rule of thumb for determining the length?

Thanks,

are you running a 23 degree headed small block or ls1? or?

ASM injected 454. GM ovalports. Hope to upgrade to 540 with BIG heads after I finish the rest of the car.

Thanks,

i would not worry about it to much you wont see any huge gains with the set of equal lengths with the twins on a big block you going to have more power than you can handle. what material are you going to make the headers out of?

Nope from everything i've read and studies you will not need equal length headers.

I'm using 316L. 3/8 flanges, 2" schedule 10 for the tube and bends. It's heavy stuff but I can walk next door to where I work and get the bends for around $5 each. It welds, smoothes, and polishes easy. The ID may be a little large at 2.15" but my next step down is 1.75" ID which I think is a little small for the 540 when that happens.

Pick a tube that has an I.D just as large as the port itself. The 2" you are going to use is fine.

Equal length on a turbo motor means nothing under power

Thanks for the info guys. I'm going on a business trip for about a week and a half. When I get back I plan on building the headers. I try to take advice given to me, but I started mocking it up and it looks like I have room for equal length. The way I'm placing the turbos, unequal length looks to easy. So for no other reason than appearance I'm going to attempt equal length. I'll post some pics when, and if I get them done.

Thanks,

45 hours of evenings and weekends in and I'm almost part way done. The drivers side took ten hours to mock up. The passenger side took five. The rest has been sanding the welds and tubes up to 320 grit with a DA, electropolishing in a five gallon bucket in the driveway, and finally buffing. I still have to weld the pieces together and sand/polish the welds. Then I get to do the driver's side. If anyone knows any tricks to get this done faster, let me know.

Very, very nice work. That stands true of all the projects on your page.

Really like the quad turbo setup on the bucket... that has to get some attention.

Looks like the tops of the snails are going to poke out of the hood a little bit... are they? If so... COOL!
