Has anyone used the GT2860RS (Disco Potato) for a low boost/ 6lbs setup? IF so,........which turbine housing did you use? 0.64 or 0.84 turbine A/R? And when did this turbo start making boost?? PLEASE,....only reply with FACTS. Opinions can be sent to my PM box. Thanks, Guys!!

Joe I think that is the standard turbo Velocity uses in there stage 1 kits...A buddy of mine has one on his busa and I rode it. Starts making boost about the same rpms as mine. Mine is a 2871 but is a dual bb turbo so that allows it to spool fast...Yours should spool a little faster with stock compression.

my velocity stage one came with a t28 I dont know if its the same as what your asking but mine starting making boost at 2300-2400 . I cant remember for sure but I wanna say full boost was at 8000 or 8500.

You should be at full boost by 5500 rpms. And yes you have this turbo.

Mine was a 28r not rs but it will be similar,reached full boost ~5000-5500 beginning to make boost ~3200-3500 ...ar64 ex
 
VR stage one(t28) with 9.9:1 cr starts making boost at 2200rpm and is at full boost(10#) by 5200rpm, not sure but I think that it spools pretty fast.

Hey Joe long time no hear, that turbo on a stock comprestion motor and a 6lb wastegate will start building boost 2200-2400 it really depends on how the motor gets loaded, also weather you run a dump or full exaust will make a bit of a differance as to just when starts it builds boost, also it will make a small differance as to how rich or lean the map is when boost starts, when you get to that point get with me and I have several maps you can try until you get your data logger up to speed:thumbsup:
