Compressor flow comparison table

[Lithium]

Hi all, I thought I'd put one of these references in here before but it seems I haven't - not sure how many people are actually using this place still but I feel like there are guys lurking about who might find this reference useful or interesting. 

A lot of the time people don't catch key details or even fully understand how compressor maps work - or don't even look at them and just go from heresay about deciding how different turbos may compare, but I've been putting together this table over the years as a quick reference to get a gauge of how certain compressors compare to cut down the time that can be wasted looking around aimlessly.

* This relates purely to compressor flow, so won't necessarily reflect the outright capabilities of these turbos as the power potential also comes down to the turbine side.  If you understand this, you should be able to use this 😃

* The inducer and exducer size listed are the mm of just the compressor wheel

* The values under the "psi" headings are "lb/min airflow" and reflect the maximum airflow that compressor supports before it's efficiency dips under 65%, or it reaches it's maximum speed - whichever comes first.

Any questions, or requests for other turbos which the compressor map is available for then let me know 🙂

BTW, the reason I came in here to "update" this list was that the Garrett G Series II range have been released and I've updated the list with their flow details if you're curious to check how they fit with previous Garretts and other brands The G-Series II G35 990 looks like a banger...

I've been hunting info on the G Series II - this is best I have found so far(Link below).

Still waiting on the G35-1150 comp map, kind of very keen

 

So how do we go about getting precision on that little table of yours ?

You'll find this link is probably more useful  Performance Turbochargers - Garrett - G GT GTX GTW Series Turbo TBG

G35 1150 map may not even get added to my list depending on how it looks, the G35 1050 already is a mixed bag for making the numbers you would expect from the compressor map due to mismatch - I don't know how another 10lb/min of compressor flow is going to make that any better.   I've left out others for similar reasons as it's already getting quite big.  

In terms of Precision, provide me with legit compressor maps for them and I'll do my thing   I'll add some more of the newer Xona Rotor options are they're pretty boss, I'd take a 68mm Xona over a G35 "1150" any day of the week - or Precision for that matter.
