Can you run a turbo system with long tubes?

If you were talking about maintaining purchased long tube headers then listen to Revolution - they will not like the added heat and pressure if you were to use low mount turbos.

Just my <.02

Speedster, I've got the same dilemma as OP. A new stroker with long tubes, but I'm dead set on the TT route. Could you PM some info on your setup? Yours is the only high mount TT I've seen, and it looks bad ass! Also, what if you heat wrap your headers and mount custom hangers for the turbos? Would that help with the heat and pressure at all?

Burns Double slip fit collectors help with cracking on turbo headers. Not for the faint hearted. I have a couple grand in just parts on these headers.

Thats a thing of beauty under your hood! Well Done!

Thanks for everyones imput and help. I think Ill continue down the same road and get the SC. But Ill keep this set up in mind for the next time...

Oh. My. Gawd. That is the best engine pay pic of a 5th gen Camaro by far.

What about using long tubes with a top mount Single setup like turbonetics has?

The kit hooks up to the stock Cats which would be in the same location of the collectors/hiflo cats or off road extensions.

What would be the Pros/Cons of using a long tube header in this application?

Thanks!

Most LT headers are not made nor engineered to carry the weight of a turbo hanging away from the flanges and all the movement passed onto it. In SST's application I believe they are using welded cast-stainless plus the distance to the turbos is not large. LPE does the same thing with their undermount turbos on the Vettes. Cast stainless is super strong and thick-wall tubes, not thin stainless tubes like on LT headers. My 2 cents.

Like a few of you I also have been tossing around the idea of turbo charging my '11 SS. IMO if I'm going to void my warranty on a $40k car when I open the hood I want it as eye popping as possible. So a set of S.S. Tubular headers with a top mounted turbo is what I'm planning.

Just some ideas if you guys would like to give your input feel free it would be appreciated.

1. Is 304 SS material good enough to use for strength? Or would it be better to goo to a 321 SS?
2. Would using a smaller primary be better for spool and velocity? Such as 1.50" or 1.625". Or a stepped design?
At what size wise would I be sacrificing power?
3. What kind of flex joints are stronger and withstand heat abuse better? Braided SS looking joints or the SS ribbed bellows? "sp?"

Thanks.

1. Is 304 SS material good enough to use for strength?To be perfectly honest no. It's fine for short term heat and not extensive temps like say an exhaust post turbo but before the turbo no I would never use 304ss. It's a nickel chromium stainless it doesn't offer the stability of 321. 321 is a titanium based alloy, If you want to get serious Fab it in 321H it's high carbon and has zero issues staying strong above 1000 degrees and it welds like a dream. Or would it be better to goo to a 321 SS?
2. Would using a smaller primary be better for spool and velocity? Such as 1.50" or 1.625". Or a stepped design? Depends 110% on your turbo choice and end goals a good rule of thumb is when sizing a system prior to the compressor is not to exceed port size too greatly but take into account the amount of volume that it will need to support. If you are staying the stock cubes I would use a 1.75" primary and a 2.5" cross over if you are going to use a single turbo
At what size wise would I be sacrificing power?Again depends on the turbo selection
3. What kind of flex joints are stronger and withstand heat abuse better? Braided SS looking joints or the SS ribbed bellows? "sp?" Braided offer more flex with the expansion if you are using it on a street car I would recommend the braided ss over the ribbed bellows

Thanks.

Hope that helps!

Thanks for the suggestions. I will look into the 321H and price the material for the headers and stay with 304 for the exhaust from the turbine to the exhaust sys.

The v-bands and flex joints that i've found are all 304 anyone have a source to buy 321H fab items or can i use the 304 for the non tubing items?

Thanks

I'd like to find a place to buy 321 as well. How about 316 stainless, would that work for this application? Anyone? I'm looking at fanning my own set of "shorty" header-style manifolds to run my turbos. You can always fab a bracket to hang your turbos and relieve stress on the system. That's where I'm leaning right now.

[sspaul]

what about the sts turbo system since its a rear mount turbo?

[kpwalls06]

I'm not a huge fan of rear mount. I'm sure it's a good and proven system, but it's not what I'm looking for.

If you want to go the turbo route, but want to keep your headers, maybe look into a centrifugal supercharger. Similar power bands as turbo's.

Turbo's are making way more torque than centrifugals.
