I believe that after some research this could be the most powerful 4 cyl FSI engine in the world without nitrous, I've spent a big chunk the last 3 years on this Sadicupra project, it was very hard and bitter sometimes but I never gave up, This are uncorrected numbers, a write up will be made but for now this is it, this was tune by myself in-house. I would like to thank all my customers because without the opportunity to tune your vehicles I would have never been able to finish this. More and better things to come! along with time slips and other projects from us at Mabotech.

Sae Corrected numbers are: 837.15whp and 724.79lb/ft
so with 12% transmission loss is around 937.61hp or 699.18Kw and 811.76lb/ft or 1100.6nm.

How does that intercooler fit its 4.5in thick, you guys must have way more room than us.
How did you make 900hp without added injectors? What octane fuel? That turbo must be
working very hard, those power levels seem out of reach of that turbo.

Really nice project!!
I understand it took a lot of time for such a project.
You use a set of extra injectors in the intake manifold right?

I replaced the front bumper support bar, cut the lower portion of the radiator support, put a radiator that bolts right nest to the condenser, custom pipes and moved some AC lines and lower coolant hoses. turbo is not antisurge which allows more flow top end, I have a big pre-turbo meth injector and I think I'm overspining the turbo at least 5-10%, so I'm literally out of turbo by a lot, If I want to take this further I will DEF need a bigger turbo. |

You do use extra injectors in intakemanifold right??
Don't believe this kind of numbers with FSI.
I run 600 hp on only FSI and it was quite some work..

Yea I'm on the same page, no one has the added injectors listed.
I dont see how the power is possible without. I guess the a4s 6466 will make the power claimed.
I'm still not convinced the turbo will flow 930hp. Everybody has them maxed around 750, and most
make that seem like top of the world.

Port injected engine != TFSI/GDI.

The DTM one has "-Ultratech additional injector ECU" listed.
I also carefully say that if they run ethanol, it is possible to make more power on the same airflow because of the different AFR. More fuel in the mix means less needed airflow for HP. Aside from knock control offcourse. I mean I was not considering BTU or octane of different fuels

Lower air-fuel ratio at peak power gives more hp per cfm. So it is possible to get higher HP when you max out the turbo's airflow. Say you make your peak power at lambda 0.8, your afr on e85 is 7.8AFR. On petrol this would be 11.8AFR. More air that has to come from the turbo. It will not be as simple like that, I also have no experience with E85. But its a theoretical approach taken from a compressor calculator sheet I have.
The GTX3582r maxxes out at 75lbs/min or something, that gives around 700hp at 11.8AFR but gives 900hp at 9AFR. Garrett formulates it as Wa=Hp*A/F*BSFC/60 to help choose the right compressor for your HP goal.

9:1 AFR will make the car not go anywhere and quite possibly even misfire, WTF are you talking about??? If you go by what any turbo calculator out there says, the most power you'll make is at 1:1 AFR because the more fuel you burn, the more energy you have. same as 20:1 producing 0 HP, when in fact 20:1 AFR can still burn and produce "some" horsepower.
