The small turbo will make boost , but over 15 pounds it starts to loose efficiency and generate lots of heat .
If you can get 17 or 18 pounds out of it it will be less horsepower than a bigger turbo at the same boost level.
Hot air expands this = boost pressure but not power.
Also a hotter intake temp puts you closer to detonation, so go higher on the octane.
Personally I would keep it down to 14 15 psi just to be save.
Talk to the MCX guys direct , they know the deal on what is save for there kit.

Yes you can have it rebuilt to a 19T and yes you will need your mcx box re-flashed.
That 310 mapping was never a good idea with the 16T. Its way off the map and to be honest I bet it doesn't make 310 anyways. Theres a reason MCX offers 290 now with a 19T cause thats pretty much all the 19T will do. Here's a compressor map for the 16T. The scale on the left is pressure ratio so 2.0 is 14.7 lbs or 2 x sea level pressure. As you can see at 2.0 the map clips off at basically the max CFM. You can still add boost but you aren't moving any more air you are just making heat and cracking exhaust compenents. When you do the math of the CFM requirements of the motor at 1000cc the air just ain't there.

The 400 turbo is another turbo then the 16T and 19T.
McXpress sell this 400 turbos if you want to have some more hp then the 19T give
Here is a video of a Apex with the Mcx 400 turbo, and Rb3 to control timing this Apex run on E-85 but this turbo work nice on pump fuel.
There is a Nytro here in Norway that also use this mcx 400 turbo and its got 360 Hp and its going like cracy!!

Okey that was good to now.
Did they say anything if the 400 turbo would be replaced by another turbo ore do they only have the 16T and the 19T now??
290hp all it will do? Maybe on a Apex but not on a nytro
.
Don't believe everything you read
.So if i have 290hp and rise boost i shouldn't notice any diffrence?
My Apex run's as an burned ferret when rising boost, BIG diffrence in power!
I would "guess" an 19T can flow up to 330-340hp, it's not much of an guess when we've seen it in real life!

Lol, noooo, the 19T is a very small charger compared to their race kit's, they have an MCX550 for ex, and some other stuff that a customer can special order, 19T is the biggets in regular volume kit's.

I guess maybe I should have qualified this statement. True the 19T will move up to 540 CFM as shown on the map, BUT, your'e also making heat so yah may make 340 hp or whatever the number is but if you ride it 40 days a year you WILL crack the stock headers, so what I probably should have said is that 290 HP is the practical limit for that turbo, if you want 340 hp I'd be looking for a larger turbo. Maybe thats just me.
