...help me read turbo efficiency charts
I believe the turbo I have is a reworked IHI RHF5. PE Japan says its based off the F4B, but I can't find anything on that.

How the hell am I suppose to figure out the airflow my engine puts out?

 

haha thats a wierd chart...I have never seen one like that

 

It's for various turbos. I found it on the IHI website I think. I couldn't find the one with the islands for different thermal efficiencies. Technically my turbo is different from that one anyways. It's possible the only thing similar is the housing and wastegate. I don't know what PE did. Do you know where to find a traditional chart?

 

hmmm never seen it like that.... do the units at the bottom say cubic meters per min?, hard to read but it would have to be something like that.

What kind of engine? I found a consumption chart for mine... i have gone to a site too with quite a few others:

may be able to fudge it a little to get close.

 

I'd go with the pink turbo...not the salmon one, but more of the pink. Yes, most definitely...pink.

 

Oh that link might be helpful. Let me read over it. It's a punny 1.8L by the way. Aww, man the bottom of the page overlaps itself. I can't read it. Wonder if its Firefox.

 

are u only looking to use a IHI turbo?

 

Well I already have one. It's a reworked one anyways. I'm just trying to figure out what it's capable of. It's an IHI that comes in a PE kit.

 

do u know how many lb's/min it flows?

 

No, information is pretty bleak. From what I understand it's based off the RHF5. I've been trying to find a chart. If you are wondering it's the PE1215S. I do know it has an a/r of .15, so it's pretty damn small. PE claims it'll flow 250ps, but that seems optimistic. Though according to this they got it up to 300ps on a CTR. I find it hard to believe it can flow well on a 2.0L that revs to 7900.
