I know that the DSM housing is restrictive, but it can see some pretty big numbers. Does anyone who looks at builds and dyno numbers frequently know what the max horsepower allowed by a stock dsm exhaust housing is?
 
More than the mods in your profile can push.

That's a real swell answer. Don't think he said he was trying to break it.

Go to the members part of the page on the top right, look at dyno numbers, they are broken down by what turbo was used, in one of the columns.
 
Well the real reason I ask is because I have a BEPS259 with the stock type housing (i.e. internal wastegate, DSM bolt on). The exhaust manifold is a forced performance.

Realistically I would probably be most limited by the stock throttle body and intake manifold.

The reason why I ask is because I want to max out the turbo. It's running about 27psi on pump gas but I think it is good to 34 psi on E85.

I need to know if I can get use a Walboro 450lph and 1650cc injectors to max out the setup, or if I need to go bigger.
