wondering if my 89 h.o will handle nitro and whats a good kit that is cheap and will basicly give me more bang for my buck?
are you talking about nitromethane? no it wont handle nitromethane. that is what nitro refers to. your probly asking about nitrous. yes that motor will handle nitrous. i have seen people safely use 150hp shot systems on that motor. look at the nos powershot system or the snyper system. those both are inexpensive and can go upto a 125hp shot. if you have biger and beter plans in the future then look at the nos cheater system it starts with a 150 hp shot and goes up to a 275hp shot. in addition to the nos system you will want to get a high volume fuel pump of some sort. a timing retard device of some type, and a nitrous filter. also check around your area to see how much it will cost to fill a 10lb bottle.
just look on E-bay they have them for 300 bucks (now all you have to do is go hunting and shoot 300 bucks) ha ha ha ha there is a tech page on how to do this
Installing nitrous, anything more than 74 hp, will likely cause damage to the stock engine over time. An engine built for nitrous should have forged pistons, good rods, rings and bearings. There is very little difference in the loads placed on the engine between nitrous in large quantities and having a blower delivering air to it. (when the nitrous is in use)
an 89 ho has forged pistons. ive personaly have ran 150 hp on my 87 short block. it had 200k miles on it when i sold it. it didnt burn a drop of oil. nitrous can be very safe if you build a safe system. you need to ensure that you have enough fuel supply, strong igniton, colder sparkplugs, right octane of fule and proper timeing. i honestly feel that a system that is rated at 150 hp will cost your at least a grand if you add all the accessorys to make it safe and easy to use.
Well that explains it. I had a 75 hp shot on mine before it cracked the block. Actually mine was a 125 shot in a 347 '89 block. The thin 5.0 block didn't like nitrous and stroker combined. The forged pistons that came stock in HO motors don't really compare to good aftermarket pistons but they're better than hypers. Many hypers don't like the sudden cylinder pressure spike from nitrous. I ran a 125-150 shot for a lot of years on a cast piston 302. Used a good nitrous controller to babysit the engine, good fuel supply and a very safe tune. Th part I didn't like about nitrous was having to pull the bottle to get it refilled at $40 a pop. Used to get about 7 or 8 good runs from a bottle.
a turbo or supercharger is usually cheaper in the long run sence you dont have to keep filling bottles. in shoping around this week for refill costs ive found the cheapes at 3.50 a lb all the way up to 6.00 a lb. that can add up really fast at 10 lbs a fill. all three systems need the same support systems like fuel and spark. doing lots of research will help you make the decision as to what will work best for you.
thats a kit gets you most of the parts. im sure that its not a direct bolt on kit. its more of a universal kit that they post adds for it towards specific cars that they feel it can be made to fit. i dont know about the quality of the parts used and would be leary of it. do lots of research on the brands used.
Please save some money for a performance transmission to go along with your increased torque and HP. The turbo is easiest on the transmission but still requires work and parts to live happily with a turbo. A blower (positive displacement) requires a bit more of a build on the transmission and the nitrous system requires the most radical build to withstand the pounding torque that the engine produces. If you make a support that will hold 10 pounds just fine (compare this to a C4 made to take 400 ft. lbs. of torque with all natural aspiration) and then drop the 10 pound weight on it from four feet above the support (compare this to a 300 ft lb N/A engine with a 100 hp shot of nitrous). The support that hold the weight just fine will break when you drop the weight so it is applied in an impact fashion. Nitrous is a lot like a sledge hammer impacting the transmission (and engine too) with a certain amount of added torque all at once. BANG goes your transmission. All the parts of the drive train must work together to get the acceleration to the ground. If there is a weak link nitrous will happily point it out to you.
