Hello.
We are going to build single rotary engine and we need tubrocharger for it.
We need only about 120hp and low boost.
And we need engine to make power on stable rpm about 5-6k for a long time.
So we need not fast spool ets, I think we need big hot side just not to make much exhaust pressure.
Could you please help me to make a choise of turbo?
Thanks.
Maybe you didn't see that I need turbo for single rotary engine? This turbo is huge!
You are correct, most people don't have single rotor engines. That puts you out of the SXE range. If looking to purchase something new this is what I would run with the vband inlet IWG;
But for 120hp it is very big too?
And I need not ball bearing, just journal.
And I really want as small turbo as it possible.
What do you think about borg warner s1bg with 0.81ar hot side ?

I think it would be a pretty good match for what you want. I would pick a spec with the larger turbine if will be on load consistently. Is it aviation? I would assume so if using a rotary otherwise fixed load for a pump or even a hover craft or something you would just use a piston motor?

I dare say it will still be too big. I was looking into small turbos for my 3.0l diesel ute a while back, (probably >200hp with emphasis on bottom end torque) , really wanted an EFR but no matter how i crunched the numbers the smallest EFR was going to be too big. Funnily i ended up using two of the turbos Slides listed, GT25, and TD04, both with billet hi flow wheels around 41mm inducers. Was looking at getting a S1bg but had trouble sourcing one. Difference in my application though was I was looking for a very tight a/r turbine housing.

I just released he only wants 125 hp total.... I thought he was asking to add 125hp on top what it's going to make non turbo...

Yes for aviation. Thats why I want as small turbocharger as it possible.
Yes, I understand, I can not find any turbo with such small compressor and so big hot side as on s1bg, maybe you can help me to find.
And could you please help me with exhaust flow calculating?
How can I calculate exhaust flow for example for 5000rpm or 6000rpm on single rotary engine if my power for example 100 or 120hp
And how to match turbocharger hot side to be sure that exhaust flow will be enouth to make necessary boost (for example for s1bg I see I need only about 0.5bar ), but to have as little exhaust backpressure as it possible?
I just use some of my experience in 13b rotary single turbo, so s1bg seems to be good, but Iam not sure.
Thank you for help and responses!
