T3 Max?
alright i have a dohc zc....and im rebuilding it at the moment *eagle rods, srp pistons, arp headstuds, etc...*
i have a 88 saab T3 42/48, 2.5" dp and exhaust, 550cc injectors.... and i plan to push the turbo to the max.....any guess on what hp/psi it will max out at

so with that assumed:
looks like it can support 30psi (3.0PR), but output a max of 230HP (25 lb/min)
measure the size of the inducer so we can determine if that's correct. If it's actually a 50 trim, then assume you can push about 250HP with it.

And every 1/32 of an inch matters. The difference between a 45 and 50 trim is very little (1.595" vs 1.674"), but their flowmaps are quite different: rated at 21 lb/min and 30 lb/min, respectively. That map is obviously is more in line with what I'd expect from that small increase in size. Regardless, both flow the most at 16-18psi. Neither will last very long at that psi though.
I'll be pushing that turbo size (50 trim) as far as I can this spring - I really want to see what they can do. All I need to do is break in the clutch and put in the walbro. Next step is the same turbo, except machined to fit a 57trim t04e compressor.

Get the T3 and get it done with , its certainly not rocket science

and you notice all the bs flags that were raised. Plus you notice they are in CO. If i owned a shop with a loading dyno, id certainly be doing the best tuning in town (ie, correction factor.)

Saab/Volvo/Chrysler T3 drop in efficiency past 15 psi, and for those willing to overspool them you can hit 270-280 whp @17-19 psi on your run of the mill Honda D16. (DOHC) ZC flow a bit better, the OP might hit 270-ish a hair lower pressure.
