 nitrous
A thing you must take in to account when building a nitrous engine is that, the parts (block, crank, rods, pistons, even heads) have to be such that they can withstand the same amount of power in a naturally aspirated engine than they will with the nitrous applied. There are some other requirements for heavily nitroused engines too that differ from a naturally aspirated engine, but that's an other thing. Although it sounds easy and relatively inexpensive to spray an engine 500 hp by just adding a big fogger system, the other engineparts that can take that amount are not. |

To Jyrki: (abt nitrous engines) Well , ofcource , definetely. What I was refering to is that you can add 100 hp nitrous kit to a stock vette motor without any mods . And it will do .

Yes, if it's in good condition it will propably live for ever. I have never used nitrous so far, so the only way I know about it is through what I have seen. I can say that 250 hp is too much for a stock engine A friend of mine had a 360 in his duster, a stock hp version with a cast crank and pistons that run 14's naturally aspirated. He bought a NOS cheater kit and it really helped the car run until he figured that "if 150 hp helps this much, what will the 250 hp do?" Well, he found out. I think the stock fuwl pump may have been on its limit and therefore the pistons burned through. However, also the connecting rods were twisted etc. etc. etc. |

I like that !
If you get more air you gotta have more fuel
That's why certain black camaros use 9 mm fuel hoses ...

Yes meant just that, 14's in the 1/4 mile. If I remeber correctly it run 14.2's at best. The first time out with nitrous it run 12.8 with the same street tires etc. |

Well, he found out. I think the stock fuwl pump may have been on its limit and therefore the pistons burned through. However, also the connecting rods were twisted etc. etc. etc.
Some stupid questions:
1. What is "360" and how much is stock hp for that?
2. What is the most nitrous, you know any stock motor has survived and what are the most common failure points with too much nitrous besides the burnt pistons.
3. Have you seen engines ruined by too much nitrous, which have twisted rods and healthy pistons?

360 is a mopar small block, the hp version was rated at 245 hp. With headers that one propably made a little more than that. The trap speeds were 160 without nitrous and 186 with nitrous.
I know one guy who used up to 400 hp fogger shot in his basically stock 440 short block; it had TRW forged replacement pistons though. The engine was in a 1350 kg Challenger and it broke a lot of parts, cracked heads etc. He run it a lot though and got about two hundred passes before the final explotion. A connecting rod broke at 350 meters and the car run 9.23/227 km/t on that run! |

nitrous
Peamine mootorite killer on ebapiisav kütusesüsteem - segu läheb lahjaks ja valmis.
Nitroga on soovitav, et mitte öelda kohustuslik, eraldi kütusesüteem mootorile ja nitrole. See hoiab nitrovärgi sõltumatuna mootori enda kütusesüsteemi anomaaliatest. Korralikud pumbad, voolikud, regulaatorid jne. enesestmõistetavad.
Teine asi on juppide vastupidavus. Kõige kriitilisemad on kolvid, siis kepsud. Väljalase peab olema piisavalt vaba vooluga. Nukk - tehakse nitro jaoks sobivaid.
Mõistagi tuleb arvestada ka jõuülekannet, rehve ja vedrustust. Nitrost pole kasu kui kummid põlevad all või jõuülekanne puruks.
Korralikuma laksu jaoks on vaja väga korralikku süüdet, soovitav mitmeastmelise retardiga ja window'ga.
Komplekt tuleb suht rikaste düüsikombinatsioonidega, süüdet algul 4 kraadi hilisemaks iga 100 hj kohta ja küünlad üks aste külmemad iga 100 hj kohta.
Alustada ettevaatlikult, proovida nitroga ja ilma ning võrrelda tulemusi - kas klapivad?
Muuseas, on olemas nitrosüsteemide tuunijad - saadad nitrokomplekti, kütusepumbad, solenoidid, sisselaskekollektori ja kõikvõimalikud mootori/auto andmed neile, ning nad panevad asja paika. Paljud 6,7,8 jne sek autode omanikud arvavad, et see $600 säästis neile kümneid tuhandeid taalasid, mis oleks läinud õhkulastud mootorite remondiks. |

Yes, it was a Duster.
I saw picture of the engine after the run; there was not much left out of it. Intake manifold and rocker arms were about the only bigger parts that survived. |

Doesn't that apply that nitrous also generally cools those parts concerned.
Maybe parts (block, heads, crank,rods,pistons) can be chosen to withstand 100hp less on nitrous motor than on naturally aspirated . What could be a proportion ?
I know that the more "heppaid " the more £££
and with each 100 hp higher the ammount of £££ rises too ...

Veel, et on oluline teada, mis mootoris toimub:
Kütuserõhu, nitrorõhu, EGT, A/F on kohustuslikud.
Tõsisematel juhtudel ja täpsema häälestuse soovi korral on vajalik data recorder - küünlad, silmad/kõrvad ja time-slipid ei ole piisavad. |

Alustamiseks sobivad combod näiteks siin:
http://www.nosnitrous.com/HiOctn/TechServ/TechInfo/NOSTech4.html
Window - süütesüsteemi osa või eraldi kontroller, mille abil nitrot saab aktiveerida ainult teatud pööretevahemikus ("aknas" ). Asi selles, et madalatel pööretel ei tohi nitrot kasutada ning piirajasse lastes võib karpasse tagasi lüüa - pealtvaatajatele tore tulevärk, aga sõitjale auk rahakotis.
Näiteks kui piiraja on 7000 peal, siis nitro võiks panna 3000-6800 pöörde vahemikku. |

Aga mis ikka võiks juhtuda karpasse tagasi löömise "feierferki" puhul : kas kogu auto kustutamine
või karpa , kapoti vigastused ?
