Big thanks to

- Paul Dykstra for info on IHI turbos,
- Quiz on the Hardcore VW Forum for the ATP brochure,
- Marcelo P. Figueira (marcelotuning) for some KKK compressor and GT turbine maps,
- Roger Enns for the rare IHI compressor maps.
- John Czving for Garrett brochure.
- Rick Chwiendacz for tracing the extremely rare T25 maps that he only had in hard copy.
- George from Greece for the other two T25 maps direct from Garrett.

Here is a very interesting document from Garrett, including some information on interpreting turbine maps.

Thanks to Rick Chwiendacz, who found some rare hard-copy T25 maps in very rough condition, which he then hand traced for us. George from Greece then sent me the -55 and -60 trim maps that he squeezed from someone there.

Garrett has seen fit to bless us with both compressor and turbine maps for the GT series. C links to the compressor flow map; T to the turbine flow map. Here is a table of info on the GT series.

Quiz sent me an ATP brochure with the GT30R maps, and a pair of dyno runs from them comparing it with a T4-60/T3 (beware that this is what we would call an "uncontrolled document" at work, having no idea what the specifics were for each run). The GT comes on a little earlier, and then proceeds to build a lot higher. Still in pdf format for now. GT30R: Maps Dyno runs |

IHI = Ishikawajima-Harima Heavy Industries.

IHI documentation is pretty crude, just outlines of the operating region without any efficiency curves.

Some comments from Paul Dykstra on used IHI turbos:

If you are junkyard shopping, look on the
turbine inlet on the bearing housing side for a cast-in "R5".
This indicates the the turbine housing is made from high nickel,
high temperature material (D5-Niresist). Also cast into the
same area is a P#, this is the A/R in mm^{2}/mm. It can
be converted and compared to other turbines, which are more
typically in^{2}/in. [efahl: Just divide it by 25.4 to
get the "real" A/R, for example, if you see 19 it's what Garrett
would call a 0.75 A/R housing.]

Roger Enns got these two maps from an engineer at Warner-Ishi.

BRL3911 | BRL4016 |

KKK was purchased by Borg-Warner and is now 3K-Warner.

Many of these maps are in m^3/s at 20C, which by my calculations becomes lb/min with a conversion factor of 162.04 (e.g., 0.25 m^3/s * 162.04 = 40.51 lb/min).
