Vortech G-trim compressor map inside This map is from CAPA's website. No more confusion.
Shows it can Flow well over 70lbs/min and 1100 cfm.
A few of us have been really spinning these units and found much more power than Vortech shows it is capable of on their website. But this flow map shows the unit can support well over 700 flwhp.
I have completely re fabbed my blower intake and outlet ducting. A full 4" on the inlet. 30% larger than the 3.5" ducting on the stock vortech kit. A constant area 2.5" outlet to the throttlebody. No intercooler.
I will hopefully see some extra airflow from the unit next spring.
I was seeing 13psi and 67lbs/min flatlined by 6000rpm with the stock vortech plumbing.

thanks for that flowmap, first one i have seen for that unit.
Would you be interested in either pics of your setup, or sellimg me your old inlet/outlet piping? (Ryan212@aol.com if you are)
i have a V9, as well as the brackets for a LS1, but no piping in or out of the blower.
I was going to fabricate some up, or find some used, whatever is easier/cheaper.
I am not looking for 600-700 hp from it, so the "stock" vortech stuff is fine for me.
Either way, good luck with your setup, and thanks for the great flowsheet for the headunit.
Thanks

Ya, but plot it out for the LS1 and you are way off the efficiency map.
You'll find the S-Trim is a much better match for the LS1.
As well as the T-Tim +.
Also note the impeller changes.

Slow, I had to use parts of the old ducting to make the new ducting.
MelloYellow, yes some of us are spinning the units beyond the best efficiency of the unit.
But even at 70,000rpm I don't see excessive heat created from mine.And I already know I am getting around 70lbs/min of flow from it. This was just the first map I have seen to confirm it's within the units specs.
The point is, the unit can flow a lot more air than was once thought to be the case.
I am not saying a t-trim would not be a better choice at 600+ rwhp.It would. A couple of us are making 600+ RWHP with these units and have no belt slip issues and a 8 rib. This is because it's a pretty easy unit to spin and does not rob a ton of HP in parasitic drag.
Not a whole lot of guys making better power than that with much larger units.
IMO it's better to max out a smaller blower than to lazily spin a larger unit. You'll get better midrange boost and faster boost response.
Not sure what you mean about the impeller changes?
The G-trim uses a 5" diameter impeller and a 3.125" inducer.
