sooooooo much emphasis on compressor maps, but i never hear anyone talking about turbine maps.

garrett has their gt stuff up for viewing
http://www.turbobygarrett.com/turbob...R_714568_2.htm

but does anyone know where i can find maps like that for the o, p, q (etc) trim turbines and housings?

 

i've called or emailed most of the turboshops i could find and nada...

 

here's what i just got from turbonetics:

Dear Sir,



We do not have turbine maps available for public distribution. Is there something that I can answer for you?








why even BOTHER posting the compressor maps without the turbine maps?

 

bumpage...

 

I believe Garrett got some.

 

yea, but only for the gt stuff.

 

anyone?

a few there, not really a map though

 

those are compressor maps. thanks for the effort, though

 

you are missing it.. there are a few that have C or T listed behind them.. click on the T just after the GTXX


GT series
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.

GT12 C T GT15 C T GT20 C T GT22 C T GT25R C T
GT25R-40 C GT28R C T GT28RS C T GT30R C T GT30R-71 C T
GT32 C T GT35 C T GT35R C T GT37 C T GT40-50/54 C T
GT40-56 C GT40R C GT42 C T GT60 C T
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.

 

ok, sorry. i'll look closer.

but garrett has all the gt stuff on their site. i was looking for o,p,q, etc flows.

 

anyone know how to contact garrett?
