Thanks for this vid. Any reason you chose 2867r vs 2871?

[@RynoRacing]

The gtx2871 has a 4mm bigger compressor wheel than the gtx2867. So I figured going with the bigger compressor wheel would get me a bit more power. And I am running it on pump 91, and only 15psi for safety reasons. Although I won't deny this turbo is very laggy for being a T28, but it is also on an oem manifold which doesn't help at all with response

@@RynoRacing hard to see the graph in the vid. I'm leaning towards the 2867r .64 not .86. and from everything I've read there's minimal power difference between the 2867r and 2871. I'm looking for around 350-380whp
