AI Thread Summary
Compound charging with two turbos can enhance power delivery by combining the efficiency of a smaller turbo with the high-end performance of a larger one, potentially improving the power curve at lower boost levels. The current setup involves a single turbo with methanol injection, but the user seeks to overcome ignition limitations and reduce lag for better drivability. The discussion references the benefits of achieving peak power without sacrificing responsiveness, particularly for smaller displacement engines. The user is considering consulting expert Corky Bell for further insights on this complex turbocharging approach. Overall, advancements in turbo technology may reduce the necessity for compound setups, especially in high-performance applications.

Hi, I am currently seeking advice and looking into the idea of compound charging with two turbos. One blowing into another.
Here is a basic article on the subject.

I am currently running a single turbo setup with methanol injection on a 2.7 liter inline 6. I know the benefits of having a smaller turbo and a large turbo would be having the efficiency of both without one running out of steam so to speak.
Now is this a plausible way to have a better power curve at lower boost such as 20psi? I am at 15psi currently, my ignition system is limiting this, but with new turbos will come a wasted spark setup.
Having some experience with this engine, it made quite a bit of peak power with a gt35 turbonetics on a different car(same motor but 2.5l). However it had a lot of lag and wasnt the greatest to drive around town. What I am chasing is the top end of a bigger turbo with the kick of a lower turbo.

Any thoughts on this at all? I am reading Corky Bell's Maximum boost again, I've been thinking aobut contacting him if its even possible to ask him questions.

Turbos have come such a long way that there is almost no need for it except for usage on small cubic inch engines that make insane horsepower.

I'm talking about 1000+hp 2 liter Mitsubishi engines and such.

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
