Drivetrain ALTA Billet 56 MCS Turbo sneak peak....
ALTA Billet 56 installed
I've had one for a while now and its amazing. The jump from stage 3 to stage 4 is a real shock.
The thing makes crazy power through 7000 RPM (if you want to twist it that high), however, the boost/power starts low in the RPM range (~200 RPM above stock) and at normal street-driving engine speeds you have massive power on-tap. I'm working with Jeff on refining 91 Octane stage 4 maps and sent him a data log yesterday.

Still running amazingly strong, it improved since my last post with new maps.
I'm working with Jeff on some cold-start drive-ability issues (minor cold stumble) and over-boost with every new map install.
These are minor. The over-boost only occurs once with the install of a new map, the ECU learns quickly and the over-boost abates. Cold start drive-ability abates within 60 seconds of driving. Jeff says he can resolve this and is looking at logs.

video/dyno
I don't have a dyno pull to post. When I get an opportunity I'll capture a video and post it.
We are actually working on a brand new website. Rather than making a new page for our old website that's only going to be up for a few more months, we're just going to officially release it on the new website.
This turbo is still for sale, and we have sold it to a few customers with great results! Still not on the website yet, sorry it's taking so long! But all the info you would ever need here: http://blog.perrinperformance.com/al...turbo-upgrade/
You're right! We must have just put it on. We haven't put it on the 2011 MCS yet with the stock tune, but it will work. We're just not sure how much power it will make, but it should make more power than stock with the more efficient compressor and exhaust wheel.
