what kinda power numbers can I expect? Also asking this question to help determine which clutch to get I want something comfortable for daily driving I have narrowed it down to a competition clutch that's single disk or a stage 4 competition clutch.

You threw a bunch of parts together with no power goal or idea of how much power it could make?

Ultracoupe

I do have a power goal I was shooting for 400+ But would like to get other thoughts who have had boosted sets ups similar to mine thoughts.

thats a big turbo for 400. A 6266 can make over 750. 1000cc injectors can support high 600s with gasoline based fuels and 400ish with ethanol. If you plan on making over 500 I would get a twin disk. Less than that a cc stage 4 or 5.

I don't mean to be rude, but this has been searchable for years. The turbo has the capability of over 720whp to as much as close to 800whp (depending on the dyno calibration,) and is only limited b the fuel used and and boost pressure used.

Unfortunately, for 400whp, you chose something entirely too large for your displacement and purpose At boost pressures between 8-17psi, on the 6262 similar builds with smaller turbochargers (52lbsmin-60lbs/min) will make more torque and usable powerband than you will.

I have seen 1000whp on a 6266 so 400 or 500 is nothing. 1000cc ID's will make over 500WHP easily on ethanol . I personally think you should use a comp twin disk which will last a long long time and is very easy to street drive with.

i don't take anything personal and don't consider your comments rude. I am new to building motors and forced induction i went back over some old notes and your right the 6266 turbo is way to big. Ill probably most likely get a 6262 like you suggested.

No. going 6262 is not what is being suggested. Stay with something even smaller, by staying out of the 62mm all-together. You want something more akin to the 52lbs/min-60lbs/min size. This is about GT3076R size or so up to similar to a GTX3071R size.

1000whp on a 6266 is possible, but what AZ_Civic is looking at is where its past the point of efficiency and flexing the compressor wheel itself. It's a dyno number, and not at all of any good use as a practical matter. I'm not saying it couldn't have been made, but it was already being pushed way past any reliable practical point. Just because something can be done, doesn't make it a good idea.
