We will be offering 3 different sized turbo setups according to the build and power goal of the project. The turbo sizing will start from GT28/68HTA and go up from there.

Yes, our TT is full catless (Gintani X-Pipe and Gintani test mufflers).
Alex, Charles, it sounds better and better all the time. The custom housings and custom impellers are really a great idea. I sent a PM regarding the Dyno Database. I look forward to getting it all in there. Hopefully we can get it all done before everybody leaves for Pikes Peak and Europe.

Dyno Database

Here's the Dyno Database entries for the Gintani Stage-2 Supercharged car. These will be part of the comparison with the twin turbo Dyno Database entries (posting those next).

I remember seeing pictures of this black E90 back in 2009. I'd guess a 2008-09 model based on that.

Since we can't see the throttle position in the video, it's difficult to judge, but at 7.5 lbs of boost on twin GT28 turbos, I doubt there's much lag. As they build the motor and crank the boost up, there might be some lag introduced (unavoidable with turbocharging), but the GT28 turbo is not a "huge" turbo. Gitani are smart guys (obviously). This setup appears to be very well engineered for response.

The 100 Wtq in the mid range must make this car an absolute animal.

I hope theres room for the new M3/M4 to produce big power like this

The new S55 is down 1 liter of displacement and two cylinders, but was designed as a turbocharged engine from the factory. It'll be interesting to see what the long term results of tuning both cars will be.

I'm sorry but these numbers are barely impressive at all. Consider that in this time period cars in this price category are making 800hp to 1000hp when spending that amount of money. All the money spent on this turbo kit to make it even with a single turbo or even upward turbo N54 Powered car? Sorry but this is sad. 600hp is not a lot these days.

You're missing a hhhhuuuuuggggggeeee portion of what was posted. This car will beat a 700hp single turbo N54, if only because it has more area under the curve.

It's a stock motor, running a modest amount of boost. Yes, it's expensive but, it costs a similar amount to prep a 335i for that much power.

There's much more room for improvement, in comparison to an N54. The built S65 that Gintani is building may well go over 1000 crank hp. N54 isnt there yet.

i agree it is pushing 600whp with 91octane and 7.5psi only
imagine having a built motor and using E85+93octane should give u atleast 3+Psi and more cooling because E85 power
plus these GT28 are small to help S65 gain some low end torque as they mentioned above

Mmmmh,not so sure about this !
Thinking about a good stock ///M3 runs about 380 WHP,and with a good tune and test pipes at the best 400-410 WHP !
So we are talking here about HP on the wheels,and the Gintani Twin Turbo runs 200 WHP more !And that's about 50 % WHP more than stock S65 !
So for me personal 600 + WHP is a lot ! No worries this car kicks your A$$ !

You're dead wrong. I hate how so many people these days play the numbers game. When you look at deltas and areas under the curve coupled with how a vehicle puts the power down, you always get surprised. Look at some of the cars that Longboarder and DLSJ5 (the two that come to mind)have taken down (all while having lower numbers than the others). Their cars haul serious ass.

This is impressive- especially without a built engine. Can't wait to see what comes from it.

awesome developments. will be great to have more options on how to squeeze more power out of this motor. I'm curious to hear more about what's possible with forged pistons and lower compression.

Stop trolling. You know damn good and well this car is a) running on 91 octane b) running low boost. Anyone with common sense would know that they have been working on tuning this car and testing it to make sure the S65 withstands the rigors of a TT setup and slowly increasing boost to make sure the engine doesn't puke a rod out of the side of the block. Like UGR stuck TTs on a Lambo and immediately turned up the wick to 14+ lbs before they did *extensive* testing and datalogging to make sure that 4lbs would work first

When spending that amount of money on what? Mods? The car itself? What other car made during the E90 M3 production (08-11) came in @ $65k and was making 680 to 850WHEELhp (Your 800-1k w/a 15% drive train loss)?

And we're not talking about *that* time period, we're talking about *now*. Since we don't even know what the official prices are @ this point, we are just speculating at how much/how little value this kit presents.

Glad I'm sticking w/the E9X platform. Given that this is a no-piggyback solution on an ECU which isn't encrypted, and considering what I paid for my car, even if this kit comes in @ $20k, I'll still be in for quite a bit *less* than a F80, and I'll have a twin turbo, high-revving V8 to boot.
