Things are looking good...

[isnms]

I finally installed all my performance mods. I've had my afpr and mkiv fp sitting on the shelf for a few years.

Things are looking good, I don't think I have to worry about the distortion in my egt signal in a specific log.

I'll up my hi boost to 14 and lean the Rebic out to mid to low 11 afr and call it good.

14... pussy.

What would be the efficiency limit of a 50trim ct26.
I had read that a stock ct reaches it efficiency level at ~14-15psi.
The 50trim is not that huge an upgrade from stock.

75% efficiency till 2.2 bar (~32 psi) at 40lbs/min (roughly 400hp) airflow

So stop being a pussy

At least I know I have some growing room.
I don't think my tires can hold that right now

Is that in a CT26 housing though, or a larger Garret style housing? He's got a 50trim CT upgrade.

Far different than a T04E housing

You are starting to blow hot at ~16 psi on a CT26 housing. Not even close to the T04E housing map you posted.

I was thinking my max, efficient, level would be 14~18psi.

I highly doubt the housing would have that drastic of a change on the compressor map. I'd say its perfectly fine to 18 psi.

Ummmm...the housing makes a HUGE difference. Compare maps for a small turbo (like the CT26) and a T04 with approx the same size wheel. I think you'll find a smaller turbo plots out to the right and will choke flow.
