i've had my MP T70 for 2 years and it's seen it's share of 20psi runs. works great as have every other MP turbo i've personally been around. in fact i bought another T70 to keep "old faithful" company under the hood
Had a t70 MP on for the last 12 months Q-trim 1.0ar , been great , no issues at all.
I think they are a good entry level turbo.
But I have just orderd a Turbonetics TC 78
Have had good luck with master power T70's as well. Upgraded one to a Q-trim wheel and helped quite a bit, felt much better. Pulls strong even at 8psi. Want to see it at 15psi though to see its "sweet spot"

Got a pair of Masterpower "gt42's"...67mm inducer...little larger than a q-trim turbine with 1.22ar's(these are some big turbos)..and a lot better set of heads and cam...should be up and running soon! Expecting 1000+ rwhp at less boost!
I had a MP T70 on my old turbo 3.8 @ 15psi for a year. Worked awesome...ended up getting rid of it just for a simple upgrade to a little bit better turbo (ball bearing turbonetics T72) But I was VERY happy with the T70 for the money...cant go wrong with them.

what is the mpt70's "sweet spot"?
boost level?
rpm(turbo)?
really depends on the motor. Mine was around 20psi, and i say that cause i never really got a chance to crank it up past that. This was on a iron headed stock bottom end 5.0 motor. not the most efficient combo.
