l am designing a turbo for a 2018 Mountain Cat DSI and I am looking for some data on max boost pressure short of internal parts becoming external parts.

Is this for personal use or are looking to make a kit you can sell to the public? IMO, 90% of consumers aren’t ever going to run anything more than a pump gas set up. Assuming a splash of 110 is needed with most pump gas kits running 5-7ish lbs. On full race gas I’ve seen guys run up to 12-14lbs. With the right turbo, inter cooler, fuel, etc you could run more, but why. Although that much boost is a riot in open bowels and chutes, it’s not real
practical to ride as a dailey ride. It’s just not needed in the type tree/boondocking most guys do these days.

What's it like riding in the bowels? Sounds like fun!

I am thinking 7 lbs with the capability of 10 lbs. I want to keep the max boost level south of when things start coming apart. Just trying to determine a safe max boost level. Thanks for the input.

You can run 7-10# with ease assuming a good state of tune. good intercooling/turbo selection to keep charge temps down will ensure a lot more longevity out of things like reeds.

Never answered if this was for yourself or for customers

It all depends on fuel. I have been running the DSI between 5 and 12 pounds of boost for a couple seasons. They rip at 7 or 8 pounds and that is sufficient for most. I recommend 50/50 or 100 LL at 5-9 and at 10 or more run 75/25.

If you keep the octane sufficient for your boost your motor will last.
