    • G-Power comes to their senses and releases single supercharger based kits for the S85 V10 in the E60 M5 and E63 M6

      G-Power stuff is not very popular outside of Europe and there is a good reason for that. It's incredibly overpriced for what it is and the company also does not provide the performance figures the American enthusiast looks for such as dyno numbers or 1/4 mile trap speeds. G-Power does have quality products but their supercharger offering for the S85 V10 originally consisted of a twin supercharger kit that started at $25,500 and only provided a boost to 600 horsepower.

      Considering there are US companies offering single supercharger kits for over $10k less that provide more power it's no wonder G-Power kits are not very popular. Not to mention if you want more power from G-Power their higher boost SKII kit starts at $32,500. Seriously. Even though it uses the same ASA superchargers as the SKI and just runs slightly modified software plus 2 psi more boost. BMW tax anyone?

      The new single supercharger G-Power SK Plus offering starts at $9997.35. Only 4.4 psi of boost is run and the system is not intercooled. That is likely why power output is claimed at only being bumped up to 580 horses from 500 which, well, is weak for $10k.

      They do have an intercooled option available with boost at 7.2 psi for $13,010.25. Now this is definitely comparable to what you can get from other companies although the Vortech superchargers G-Powers competitors are using likely have more power capability. The ASA blower (depending on which model, as G-Power does not specify which ASA blower they are using) likely will offer greater response down low but it will not have the same top end flow capability of the Vortech units.

      That said, G-Power will raise the boost to 8.6 psi with this system in an SKII offering which includes high flow cats for $19,857.75. At that price point this makes absolutely no sense as one could buy the SKI system, get some test pipes, and change the pulley themselves having more power with a spare $7k in their pocket.

      In all honesty, there are better options than G-Power on the market especially for those in the USA. The G-Power stuff is well tuned and the hardware is fairly good quality but this is too little, too late, for too much. Additionally, where are the dynos and the blower specs? What about some performance numbers? What G-Power truly excels at is marketing to those who don't know any better. That is why they can get away with calling themselves the leader in BMW aftermarket supercharger systems when they clearly are not.

        My awesome 3D printer can do the same thing! Then the maco paint job will do just fine to go you to pay 30k for a car I can buy for 30k. Sorry I'll go buy a E55 amg and either run a Weistec setup or a Eurocharged setup for a whole hell of a lot cheaper and buying a much cheaper car with a lot of less miles in my area. 60k on the clock m5 = 30k 60k on clock e55 amg = 15k in Joco KS.

        E55 is a different car with different power delivery.

        NICE! Interesting there still shelling out kits for the S85.. Like you said sticky, a little too late here. This $10K-13K kits are ALOT better priced but ESS has really taken over the FI S85 at the moment, this is a nice mix, gintani aswell but haven't heard much on them either since there release.
        They even have new M3 stuff out aswell..

        G-Power's stuff is for a different crowd (the Brabus/Manheim racing type of clientele) that aren't nit picky with technical data. I think we can all agree that the G-Power Hurricane RR is one of the most powerful S85 packages you can buy and that the quality of their materials is never lacking.

        IF it wasn't for that ridic price, G-Power would def be a solid product option that I'd compare to Evolve

        Anyone paying $40k+ likely expects the numbers to be delivered.

        And G-Power isn't anywhere near the level of Brabus.

        Anyone can get an S85 built with low compression pistons, get a big blower like a YSI, and make the Hurricane RR look like the overpriced joke it is. That said, it's a nice package for those that don't any better or have money to burn.

        If it's that simple, how come nobody's done it? Especially if a higher power kit could be made for less, you'd def capture a larger share of the market.

        *I understand there is no where near the same aftermarket following for the S85 vs the S65, where there's 5 mainstream supercharger options

        Nobody said simple what was said is there are better options for making power which there are. Is Brabus the best option for power? Hardly.

        Just like the G-Power S65 setups get the crap kicked out of them by serious tuners so do their S85 setups. Marketing a name brand is what they do best.

        I mean Brabus could probably build you an out of control package, but you could probably get the same power & nearly the same quality from a Weistec or RENNtech.

        But these are businesses, and sometimes marketing is more important than a quality, bulletproof product. Just look at the E90 with the Vishnu smoke screens, M3P and all E9x M3 ESS dyno graphs that run 13+ AFRs above 6.5k, or how you never hear how unreliable the UGR Lambos are, etc etc.... To each's own though, if you've got the cash, spend as you please

        I'm sure they could but they are a poor value.

        Not for the consumer.

        Well I didn't go with G-Power when I wanted a high powered M3. G-Power also doesn't have anything to show that is on the same level. Brand name versus serious tuning.

        Now that they see people (Ameicans) won't pay for their name they are trying to attack the sections of the market where they are losing out as the S85's have dropped in price and nobody will pay $40+k for a supercharger. There are better options out there regardless.

        People are quick to forget who funded the tuning of these platforms, tuning that pretty much everyone uses now....

        No you raise a good point. G-Power has access to the codes before everyone else.

        100% agree that the consumer is the one who most often gets screwed over. But that's why it's so important that if you decide to modify your car, you do your homework and investigate the setup, vendor/tuner, and what works with the car

        Totally understand, I mean G-Power is also in Germany where (as an aftermarket company) it has to meet TuV standards, which certainly explains a "price premium" that isn't necessary here in the US. G-Power does have a kit rated for 720 BHP, which I believe is the true 60-130 record holder (not sure how you've got two VT600 cars going ~.5 second faster than every other car running the same or higher power kits).

        And I don't think arguing the cost of the car vs. modifications holds much water. If you look at most of the highpower cars out there (1k WHP+), regardless what platform you pick (Vette, GTR, TT Lambos, Supras, Porsches, etc) the cost of the car usually is ~1/3 the total investment.


        And like @s62 said, companies like Alpina, G-Power, Brabus, Manhart, etc etc have access to a lot of OEM stuff that your more mainstream tuner will never get.

        Well it's not that the other tuners won't get it. If G-Power or Brabus doesn't get it nobody will get it. Stuff trickles out.

        They just get things first and so they can charge a premium.

        Certain people at BMW and Mercedes make a lot of money selling codes. G-Power just happens to know the right people so they could do their twin SC kit and charge a premium until the market adjusted which it did and now G-Power has to adjust their offering.

        Developing these kits was a bit more involved than just "getting the right codes".

        Everybody takes their own approach with the hardware. The software makes it all possible. It's the most important step. I can find you a few dozen US companies that can put a supercharger on a V8. I can't find you a dozen that could tune it.

        Bingo - and that is why the followers can offer cheap kits when they can mostly bypass the software development stage.

        And the original company that did the actual development and had to deal with the costs involved => their pricing.

        G-Power probably pays more for keys early on but they also get hooked up faster than anyone else. Their stuff is still overpriced though.

        So that explains why they went single and cheaper now?

        You make a valid point but their pricing always has been out of control. They didn't have much of a lead in the M3 market although they did come to market very quickly.
