Porsche Crest Center-Mount Variable Turbo Conversions are here...

Some of you may have been following this turbo conversion over the course of it’s development. Those who have know that we’ve been working on this project for about a year testing everything imaginable to reach maximum performance. We’ve tested several different turbine/compressor combinations, turbo orientations, charge tube designs, header layouts, collector designs, and list goes on. All of our testing has been done with full data-logging on the street (daily commute), the track, and the dyno. Being one who has been around the 930’s for a long time (former Imagine Auto guy here) it really put a smile on my face to make this turbo conversion a reality after joining the team at Aerocharger. Transforming the 930 from a car that struggles to pass modern cars on the highway to a force to be reckoned with by a simple bolt-on conversion has truly been a satisfying experience. For those who have been waiting patiently as we perfected this conversion, I’m glad to tell you that the wait is finally over, as we will be shipping the first production round later this week.

Here are a few key details about this turbo conversion:

-Full boost and max torque is reached before 2,500rpm

-Easily adjustable vanes to allow the end user to effectively control the responsiveness of the turbo

-Boost is easily adjustable from .8 BAR to 1.25 BAR (depending on your max altitude)

-Compatible with any stock or aftermarket intercooler setup

-Compatible with any fuel system be it CIS or EFI

-Mellow exhaust tone, no droning while cruising

-Fits neatly under any stock or aftermarket bumper.

-Available with or without heat package

-Complete package with everything you need for installation including hardware and gaskets

This now-famous dyno chart shows the .8 BAR comparison between our system (purple) and several runs with a bone stock 930 (green, light green, and blue). For those who haven’t seen this chart before it should be pointed out that all dyno runs were at stock boost levels. Notice the torque curve comparison (dashed lines represent torque) between stock and our turbo conversion. Where the stock 930 didn’t hit peak torque until 4,500rpm, we managed to hit peak torque just before 2,500rpm and nearly carry it all the way to 4,500rpm. This drastically improves drivability, especially on the street. It should also be pointed out that the stock turbo system struggled to even break the 200hp mark before 4,000rpm, which is unacceptable. We were pleased to hit break 200hp almost 2,000rpm faster than the factory. Those who have had the opportunity to drive our test car were blown away by the performance and responsiveness. Many were convinced it was a fully built motor running high boost and couldn't believe it was a simple bolt on package at stock boost levels. This turbo conversion is truly something that must be experienced to completely understand the difference in power delivery. It's a completely different car.
