Yeah, you can always add a cutout that can be opened when you want to get a little more power out of it. We didn't see much of a power gain by running no exhaust vs. our 3" exhaust on Ryan's car until it was past 550whp. Then it gradually made more power with the open exhaust the higher we went from there.
Why were the last 3 posts centered and wider than the rest?

It's just very hard to fit a cut-out on the kappas. None of the kappas that I saw with a cut-out was able to fit a cut-out near the dp.
but we'll see what happens.......
I just want the set-up to work first...then fine-tune it later

035 wall tubing? god the last time I welded with only 35 amps... wait I dont think I ever have. Last few welds I've done I've just had recommended amperage between 300 and 500 and just turned the knob till it stopped at 300.

4'' down pipe of a thousand cuts. and now for a recirc pipe where no room exists.
everything fits like thread in the eye of a needle
waiting patiently for the compressor v-band kit to finish inter turbo pipe. 304L

What would basically happen in that case is it would be the equivalent of a larger turbo, but retain the quick spool too. That's why some V6 and V8 cars opt for twin turbos over a large single. The downside is the cost and complexity.

In an LNF, you'll end up having ONLY having 2 cylinders supplying exhaust gasses per turbo....which I think will NOT retain the quick spool that an ordinary LNF w/ only one turbo.....

I wonder if a tricked out exhaust manifold could somehow circumvent the 2 cylinder issue. The more I think about that though, the more it seems like you'd be right back to the same issue again.

unless probably getting a lot smaller turbos than the k04? maybe a pair of gt2052?
each flow max of 23lb/min
so it might work! Or also add a couple of quick spool valve?
My head started aching thinking about having twin turbos on an LNF.....lol

that's why I was planning to have the big turbo installed remotely before............but I ended up chosing to have the two turbos inside the engine bay. Way more impressive to look at
Plus I think more effective.....

Im gonna run 2 k04's on my ss when I get it back just because I have the extra turbo and its one more custom trick to do with the car lol. only thing im debating is do I have one feed the other or do i have a Y into the charge piping to combine them?

You wouldn't want to run them in series either. The idea behind compound turbo setups is to use a small turbo for quick response at lower RPMs, and the resulting increase in power output is what allows a larger turbo to spool even though you have a small displacement engine.

2 K04s running in parallel on an LNF will be pretty laggy. The only time there is an advantage to running twin turbos is when you have separate banks and you can decrease the volume of exhaust pre-turbo by running one turbo on each bank.
