So the car is ready, good fuel consumption is reduced, it will take 15 liters less in the city.
drives like normal cars with perfect gas pedal reaction and no burning fuel in the exhaust.

400 German horses from 5500 to 6800.
max boost 0.85 bar.

 

Well done. So you went from 310 stock to 409 , is that correct or am I mixing two types of HP’s ?

What was the cost ?

 

Keep in mind - dynos vary from manufacturer to manufacturer, shop to shop, etc - so one car will get different numbers at different shops. They are most useful to compare your own car before and after mods, using the same dyno - to see the difference. Preferably at same/similar ambient temps, too.

before tuning I made detailed measurements of acceleration, the car should come to me at the end of next week and I will measure acceleration again. Everyone believes that the horses from the RS Tuning dyno are real German horses. Before tuning, the power measured on the same engine dynamometer was 325 horses, so as much as a standard car. I was very impressed how the engine behaves during normal driving in city traffic, just like in a modern car ... and on the highway it accelerates really strongly and smoothly. For the first time I see the exhaust pipe in this car has a bright color, it has always been pitch black.
picture bellow on 4th gear.
I believe it will do 300kmh and i will test it.

 

Here is 5th but there were no space in the highway to go faster.

 

I am pleased to hear that you are pleased! I have to agree that the final test is the actual driveability of the car: around town, low speed, idle, A/C on, followed with your full load autobahn. EPA used to call this LA Freeway cycle which meant wide open throttle down to a full stop to idle followed with low speed crawl.

But I still am not sure what German horses are? DIN PS? vs. NET SAE? or are Arabian horses better than other horses?

Here is a picture of from my HotRod (last year) on an EPA certified test cell on an Eddie Current engine dyno at one of the best for the Detroit auto makers; 2.9L Dual Plugged, hot cam, XDI, custom Webers, Great American Horses here!

 

I have read in the past that: The Porsche 964 Turbo has a speed limiter , I have seen between 169 and 174 MPH.

I looked in my factory manuals but cannot find a reference.....I would like to know more about this

 

I will ask but I don't think so, stock car won't go faster than 270kmh as turbo has no power to keep the boost.

 

very nice

 

So I had to chance test it immediately after delivery

Here is before the tuning


And after







Here is before






And after






Here is 300kmh run and just 0.85 bar boost and its maximum.

 

Guys, your exhaust pipe also has this color? 🙃

 

Agree..there’s no getting there on CIS. Probably with a custom fuel head, much bigger fuel lines, a bar above 1, , a one off warm up regulator, 7th injector for the extra fuel on the higher rpm’s and a few other tricks that might get you closer to 425-450hp.

 

Guys, it doesn't matter what kind of horses they are, what matters is the acceleration times. It would be nice to see the acceleration times of your 964 Turbo.

 

Those are great acceleration times but your original statement was based on 500hp+ on CIS. Keep in mind many of us have dealt with CIS systems on our cars for many years, so when a claim for high hp is made there are many doubts because of the limitations the system has.

 

Engine has 409 HP and 301kW and never mentioned 500HP.
I heard there is company in the U.S able to modify K-Jet to deliver fuel for more than 500 HP.
