Se vede ca le are omul asta... Dar atunci, de ce zic astia la instructiuni numai cum sa-l montezi si nimic de reglaje ??? Astia asa fac reclama la sistemele lor: \"se montaza intr-o ora, fara modificari la motor\". Eu cred ca tu vorbesti de solenoizii care baga benzina sau NOS in foggere, dar nu stiam ca astea se regleaza. Cred ca ce ai zis tu acolo se refera la motoarele cu sisteme directe dar motoare de competitii, nu cele de strada. Peste tot unde am cautat, la cei care vand sisteme NOS nu zice nimic de reglaje. Mai mult, unele zic sa nu schimbi nici pompa de benzina. Altele sunt facute sa legi o mufa, bagi un fogger si gata, ai shot-uri de pana la 200 de cai. Nu stiu ce sa mai cred. Parerea mea e ca la sistemele simple de strada, cele pe care le stie toata lumea, nu trebuie sa faci prea multe reglaje. Stiam ca solenoizii baga benzina constanta, si ca jeturile sunt cele care dau puterea si amestecul. :roll:

Functonare ,Componente, preturi, Plata in rate ! Montare ,Service, daca stiti ungureste www.nitrosystem.hu
PT cine nu stie ,pretul in ungaria este de 800 euro,montarea este simpla ,
cel mai bine se preteaza masinile japoneze,care au piese *biela piston etc(
mai de calitate.nu este nevoie de reglaje , dar este bine de a efectua si
clasicul tuning> admisie, evacuare .Este interzis folosirea nos la turatii sub 2500 si la turatia la care computerul masinii limiteaza motorul, de altfel se poate cumpara o mica electronica de protectie.
Un prieten ce are firma de piese auto aduce la comanda doritorilor chit complett la 1100 euro

nu stiu daca e buna afacerea cu nitro :roll:
prefer sa iau un model cu motorizare de varf decat unul inferior si apoi sa cheltui in nitro care imi poate aduce si surprize. :wink:

poate tot in ungaria reusesti

uite cred ca e situ lu zbuciumus... scrie ca au statie de refueling..
incerc sa trec pe la ei saptamana viitoare , in principiu as avea de unde sa fac rost de un sistem dar ii lipseste un solenoid

p.s. pauladrian... orice modificare adusa motorului ii scade viatza, o instalatie nitro bine reglata este unua dintre cele mai putin nocive modificari daca folosesti butonul cu \"cap\"

practic nitro actioneaza ca o turbina doar ca o ai pe buton si trebuie sa incarci butelia

daca vrei ceva care sa nu iti afecteze viata motorului pune o instalatie de injectie apa/alcool ,probabil o sa castigi doar 5-10 cai dar iti protejeaza motorul si un kit costa undeva sub 200 euro (randamentul maxim il da la motoarele turbo insa)

Il asteptam pe ZETEMTE sa ne spuna cum e sa ai N2O pe masina si cum ia fost reglat si etc.

Am scris ceva in alte topics

Instalatiile de injectie apa/alcool se folosesc la unele motoare turbo cu compresie prea mare, pentru a impiedica aparitia detonatiilor; nu dau ele insele puterea, e un intreg sistem care ajusteaza avansul + injectia de benzina + presiunea turbo + injectia de apa/alcool, uneori si cu un ECU separat de cel al motorului

Cum functiona sistemul apa/alcool la origini:

MW 50 was a 50-50 mixture of methanol and water (thus the name) that was sprayed into the supercharger of German aircraft engines primarily for its anti-detonant effect, allowing the use of increased boost pressures. Secondary effects were cooling of the engine and charge cooling. Higher boost was only effective at altitudes below the full throttle height where the supercharger could provide additional boost pressure, while the smaller secondary effects were useful even above that altitude.

MW 50 is something of a misnomer, as it is actually a mixture of three fluids; 50% methanol acting primarily to achieve optimum anti-detonant effect, secondarily as an anti-freeze, 49.5% water, and 0.5% Schutzöl 39, an anti-corrosion additive. The similar MW 30 increased the water to 69.5 and decreased methanol to 30%. This increased the cooling performance but made it easier to freeze, intended to be used for lower-altitude missions.

The effect of MW 50 injection could be dramatic. Simply turning on the system allowed the engine to pull in more air, boosting performance about 100 hp on the BMW 801. However the MW 50 also allowed the supercharger to be run at much higher boost levels as well, for a combined increase of 500hp. MW 50 was fully effective up to about 6,000 m, above which it added only about 4% extra power.

Aircraft generally carried enough MW 50 for about 10 minutes of use, allowing them to increase their climb rate for interception missions. Fittings for MW 50 first appeared on the BMW 801D in 1942, but it never went into production for this engine because the cylinder heads developed micro-cracks when MW 50 was used. Instead, the DB 605-engined Messerschmitt Bf 109 was fitted with an MW 50 injection system. Later engines designs all included the fittings as well, notably the Junkers Jumo 213, which relied on it in order to reduce non-boosted performance and tune the supercharger for higher altitudes.

MW 50 was not the only charge cooling system to be used by the Germans. Some engines dedicated to high altitude included an intercooler instead, as they would be needing the cooling for longer periods of time. The 801D also included the ability to spray gasoline into the supercharger, in place of the MW 50, and while this was not as effective it did increase boost without the complexity of the additional tanking and plumbing. Additionally many of the late-war engines also included a system for high-altitude boost, GM 1, which was intended to add oxygen instead of improve boost levels.
