  1. Hallo, ich bin der Designer dieser Auspuffanlagen. Die verfügbaren Versionen sind: Rmp Rpm+ RpmX Torque Torque+ TorqueX und sind für diese Motoren verfügbar: Px 125-150 Px 200 Cosa 125-150 Cosa 200 Für insgesamt 24 Varianten, für die Vespa T5 ist die Px125-150-Version mit Adapter in Ordnung. Die Torque-Version hat einen 5 cm längeren Krümmer als die RPM-Version Die Standardversion verfügt über ein 16-mm-Terminal, die + -Version über ein 19-mm-Terminal und die X-Version über ein 22-mm-Terminal. Auf diese Weise ist es möglich, sie sowohl an Motoren mit Membranventil und großen Vergasern als auch an Drehschiebermotoren mit kleinen Vergasern anzupassen. Derzeit gibt es nicht alle Versionen auf 10pollici.com, da sie ein Problem mit der Website hatten. Ich freue mich auf die Bewertung von freakmoped. Alle Fotos finden Sie unter diesem Link: https://www.facebook.com/pg/WhiteOneRacing/photos/?tab=album&album_id=2614314705335937 Wir arbeiten auch an einigen Lambretta-Schalldämpfern für CasaPerformance Ich hoffe ich habe verständlich geschrieben, ich habe Google Übersetzer verwendet. guten Abend
  2. Tests are continuing: After yesterday dyno, we decided to do some modification to shorty prototype, modify the calibration of the bench and also try a new type muffler the Proma (with increased manifold) and MDM Easy (very appreciated on stroke 43mm engigne). In the graphs, you can appreciate the power difference, being equal all parameters among the tested exhaust, I remember being: - The Sito Shaft; - The Polini "Banana"; - The Proma with increased manifold; - The MDM Shorty; - The MDM Easy. The engine was not changed. The results I differ from those posted yesterday because today we managed to find a better setting of the parameters of the bench, however, remember that the data obtained are only for comparative purposes since the dealer calibration is not final. The comparison highlighted the excellent performance of the last born is compared to aftermarket mufflers from more than decent performance to both the MDM muffler best-selling ever. with the Sito the engine had 11,58hp to 6256gir./min .; with the Polini the engine had 9,96hp to 7938gir./min .; with the Proma the engine had to 13,10hp 7502gir./min .; with the MDM Shorty the engine had 14,57hp to 6499gir./min .; with the MDM Easy the engine had to 15,22hp 7099gir./min .. https://www.facebook.com/gianluca.marri/videos/10206722013069281/
  3. The engine in question was made on the basis of crankcase PK first series (2 holes), mounts a 102cc Polini cylinder with the exhaust slightly less than 180 °, reed valve Polini manifold with carburetor SHBC 19mm, standard crankshaft adapted to reed valve, 26/69 primary and standard gearbox.
  4. Hi Guys, I wanted to let you know about a product that I executed the design. It is a muffler for small-frame which also mounts in the Vespa HP without removing the battery or the spare wheel. I could test it on the dyno with excellent results, also making comparisons with Exhaust Polini Banana and Shaft site. Sito Shaft 10,41cv a 8475gir./min.;Polini Banana 9,47cv a 9303gir./min.;MDM Shorty 13,79cv a 8975gir./min.. hope you like it https://www.facebook.com/gianluca.marri/videos/10206708168283170/
  5. This is my Piaggipolinossi: Piaggio cylinder, Malossi piston, Polini head, stroke 59mm
  6. are just prototypes, mufflers final will be more beautiful
  7. https://www.facebook.com/media/set/?set=a.663652760402151.1073741919.151893714911394&type=3 the crankshaft
  8. cylinder 185/128, head 11,5:1 squish 1,2mm the operator of dynojet told me yamaha 500 mk1 t-max has 28-29hp on his dyno and if on my Vespa I decreasing the main jet, could come to 27-28hp.
  9. into the boostport? ??? please using simple terms that I can translate easily the engine: https://www.facebook.com/media/set/?set=a.663427803757980.1073741918.151893714911394&type=3
  10. Finally I did the test at dynojet. The engine: Malossi MHR 221 Polini Head V-force4 Rd350 valve phbe36 megadella XL crackshaft by WhiteoneRacing primary 25/62 DRT Gearbox standard px200 26,53Hp - 2,68Kgm - 160km/h
  11. Tomorrow I will the test to the dynojet. meanwhile we have developed another megadella for engine with max displacement 210cc:
  12. On forum responsible for sales it is Koyote 78. About the development of the muffler I can say: To understand if an exhaust is better than another do not need the test bench, the test bench is necessary to understand how is better. The muffler megadellaXL is the best megadella for big cubic capacity engines, how much better we'll know next week (I hope).
  13. the XXL it's for mastrocamillo, he tested it on his Quattrini252.
  14. in a few days I modify the lth-box, replacing the o-ring manifold with a traditional and the discharge tube of 18mm. This muffler proved to be too closed for motors with more than 215cc, a lot of torque but low power.
  15. after megadella XL comes XXL as far as I'm waiting for the test bench, let me know when I can go to test vespa. Unfortunately my vehicle is too short and must build me a adapter to make sure that the wheel touches the roller; There will be wait next week.
  16. the sound: https://www.youtube.com/watch?v=Y0pmPOifrLU
  17. Maybe you did not read too well because in your eyes the coppainfaccia of 26 May . But I wrote that soon execute a launch at the counter to measure the actual power to the wheel. I'm not a chatterer, you will in a few days the graph.
  18. Yesterday I tried the muffler, what about ... a real bomb ... the result was that the muffler is perfect for this engine wheel hard to 9000rpm with a high torque. I will talk about the test bench knowing what values we are talking about but I think it is my goal to get to 30hp is reached. the sound is higher than normal but is not annoying and in any case is less than the noise produced by the reed valve intake. I will soon be posting a video.
  19. The collector of the form similar to that proposed by LTH is only suitable for mufflers designed to take advantage of the torque at low engine speeds
  20. Next week I will go to the test bench and if possible I will make the comparisons with other exhausts. I am sure that my MHR221 with RD350 valve and 36mm carburetor will exceed 30 hp with this muffler
  21. 1-1,5mm stretch of the ducts opposite to the discharge, does increase the torque. In my case, having increased the exhaust phase, to correct excessive differential intervened on stations with a final timing of 180/115 and 125 central
