Lazzaro99 1 Report post Posted May 23, 2018 Simple! to have more power? Share this post Link to post Share on other sites
Rich 953 Report post Posted May 23, 2018 the only reason why. Share this post Link to post Share on other sites
Sausage 114 Report post Posted May 23, 2018 1749vb is a good match with right injectors and FMIC and obviously a map, if you have those and run out of power with it you must be up near 200hp? You need to be on 4 pot flywheel for clutches as well. You can go bigger but will be more laggy. Share this post Link to post Share on other sites
mk2 120 Report post Posted May 23, 2018 you need to do more than just increase air throughput... if you throw more fuel in, with everything else stock to generate lots of black smoke, you'll get a fair bit more power, without even getting your hands dirty Share this post Link to post Share on other sites
Lazzaro99 1 Report post Posted May 23, 2018 For now they are on 150 hp In the map i gave 80% of fuel I would like to give more 20% the injector is stock, the clutch has a few kilometers and for now it's fine But the problem is the pression of turbo that often changes alone from one day to the next... I think it's the fault of geometry What do you mean for FMIC?? @Sausage Your advice is always welcome!! Share this post Link to post Share on other sites
Sausage 114 Report post Posted May 24, 2018 (edited) Post what you have done to the engine and map (or send me the map via pm). FMIC = front mount intercooler Edited May 24, 2018 by Sausage Share this post Link to post Share on other sites
Rich 953 Report post Posted May 24, 2018 the lupo tdi has an fmic as standard. Share this post Link to post Share on other sites
Sausage 114 Report post Posted May 24, 2018 yes but it is hidden behind the bumper and not up to big power. Share this post Link to post Share on other sites
Lazzaro99 1 Report post Posted May 24, 2018 If you see on the front is FMIC of grande punto 1.3 mjet 90cv Share this post Link to post Share on other sites
Sausage 114 Report post Posted May 24, 2018 Nice, how many litres is the IC core? Share this post Link to post Share on other sites
mk2 120 Report post Posted May 24, 2018 ooh, someone's gonna do some calcs... don't forget you can move the pressure sensor, blowoff and dump control to right next to the inlet valves. reduce down swept volumes, speed up flow, increase pressure. Mmmmm. Poweeerrrr..... Share this post Link to post Share on other sites
Lazzaro99 1 Report post Posted May 24, 2018 Explain yourself better, it’s interesting... @mk2 i don’t know how many liters is my IC @Sausage here we see better Share this post Link to post Share on other sites
mk2 120 Report post Posted May 25, 2018 go read some books... way too much to write here! good first book would be this. old, but still fresh. it cuts out a lot of the physics and maths, with just the juicy bits. "david vizard how to build horsepower". it was required reading at my college. Share this post Link to post Share on other sites
Lazzaro99 1 Report post Posted May 25, 2018 where should I put the pressure sensor?? I don’t have the blowoff What do you mean for the control of exhaust?? Share this post Link to post Share on other sites
Sausage 114 Report post Posted May 25, 2018 (edited) Measure the silver core L x W x D and get the volume, ideally you need around 7 litres for 200+hp. Dont put a dump valve on a tdi. Edited May 25, 2018 by Sausage Share this post Link to post Share on other sites
