    • First E9X M3 S65 V8 supercharged with Vortech YSI - Gintani Stage III+ M3 supercharger teaser + pictures

      We have all known for a while now that Stage III supercharger kits from Gintani are coming. There are a handful of cars running around now but they are running Vortech T-trim blowers. Due to the volumetric efficiency and high revs of the S65 M3 engine the fairly large T-trim gets maxed out fairly quickly. In comes the bigger, badder Vortech YSI. As you can see from the pictures the YSI fits, just barely though. The supercharger casing does need to be modified slightly in order for it to fit without issue.

      Part of the delay going to this big blower was the bracket. The bracket needed to be re-designed to handle the YSI and make sure it would not flex. The bracket on this car is not the final design. We saw the final design on another M3 and it is gorgeous. We were not allowed to photograph it though so as to not give it away. Understandable at this stage in the game.

      What we can tell you about the Stage III is one will be able to get it with a YSI if one chooses. The T-trim is also an option and means if one upgrades from Stage II to Stage III they do not need a new blower. We are not sure if they will just refer to the Stage III with a YSI as Stage III+ or something different.

      The car here is running the YSI with meth on 91 pump gas. It has seen various boost figures up to 18 psi. It turns out, even a blower like the YSI can be maxed out on the S65 at stock displacement. The car here has also been revved quite high as well and the YSI has kept up although it is nearing the end of its efficiency range. This car is a daily driver that has been beaten on since the beginning and continues to be driven hard with the Stage III setup. Some areas that needed upgrading were discovered during the durability testing which will be going on the other Stage III cars now as well.

      More details will come soon but for now enjoy the pictures. The owner described the car simply as silly fast and with the power figures we heard we do not doubt him. We can not go into the exact numbers but suffice it to say they should satisfy just about everyone. With not really any room for anything bigger this is going to be the biggest power upgrade available for the S65... for now.

        12psi on the 458 motor will do me just finnneee!!!!

        pulley sizes? 10 rib?
        does the air flow up through the aftercooler and then down into the throttles? i cant quite tell.
        can we see the heat exchanger for the after cooler? is it running a pusher fan on the front of it?
        what thickness and material are used for the supercharger bracket?
        what IATs are you seeing?
        it looks like those engine covers direct air towards the intake filter. true?
        is that a reservoir for the aftercooler system at the rear passenger side of the engine bay?
        what water/meth mixture? more info on the system?

        so... gintani...how bout those questions?

        Once we fully complete this setup, I will answer all of your questions and post all the details about the kit!

        They don't want to give any competitors an edge. I think it is too quiet personally, but I also understand their perspective. We are all anticipating the Stage III.

        Is it running yet? Any graphs, 0-30, 0-60, 60-130 runs yet?

        Reference the bold: "My car will have the same setup."

        This particular car has been running for some time as you could probably see from the original post date. I wonder about your reading comprehension at times.

        There are no public numbers on these but expect 7XX at first.

        Without proof we can't believe 7xxwhp here. What is the most power made so far on a sc setup?

        Don't believe it then. I know the dyno numbers but can't share them so guess you have to wait.

        So teasing without numbers. Gintani needs to learn from HPF. HPF is top notch with things like promoting kits, and customer service.

        Um, this was just me stopping by and taking some pics of the first YSI setup. Smart move on their part to release numbers when it is ready not when they are tuning and testing. That way they don't end up looking like ESS with their S85 kit that was teased with numbers but still amounted to nothing more than a tease.

        Plus, let's be realistic, even if they posted numbers you would hate on it.

        You do realize this is more info than has been posted on any YSI setup on the E92 M3 ever?

        There is more, but it is being kept under wraps for a time(how long we know not).

        You know the boost. All that is missing is a dynojet dyno chart which I'll be glad to provide as soon as it is possible.
