Soooo, I didn't check on this for sure, but Evo X variant coming? If not I am moving on to a t3

Ps. Chris is this why you were looking for a tactrix a few weeks ago?

EVO X will be covered , and I think the tactrix cable we had ended up getting a lose connection.

AngryEvo8 - Boost level is in the video on the bottom of the dyno sheet

Chris/Adam,

I just noticed that your Dyno graph looks like the turbo is inducing creep... Are you using a 25psi internal wastegate preloaded like a ****?

I wouldn't say its creeping as it hits ~40psi right about where you'd expect it. Creep is usually meant to describe boost that is increasing past peak boost. If you saw it continuing to increase to 6-6.5k I'd say you could call that creep. It however looks like it is able to create a decent amount of boost before that, unlike your single scroll black When running boost that high not all turbo's will have a very slopey boost curve; some jet up to a certain level then take a bit to keep moving past that point, which might be the case in this test. It could also have something to do with the boost control method as you mentioned, w/g or bc.

We are running an internal wastegate in combination with an external behind it so we can retain the spool characteristics of the internal and have some backup when exhaust pressure would normally force the internal open

I thought about doing the same on mine, now to the second question, what is the usable shaft speed of the turbo and what was it spinning holding 37psi out the top?

Great questions that I hope to eventually be able to answer for you lol, to make a long story short this power level is not recommended, we will be marketing this version of the turbo with a maximum recommended whp of 650.

I will see if I can get my associate Bob in here to field the above question as he will be better suited than I, but basically running any turbocharger at its limits will have an adverse affect on longevity and we have to consider how we will be structuring our warranty program. Some of our competitors discourage the use of external wastegates simply due to the fact that exhaust pressure will eventually force open an internal wastegate effectively creating a maximum boost pressure and limiting shaft speeds. There are a lot of considerations to be made in regards to the launch of this program
