nos and hyper eutectic pistons??
 

as i read, i see that many manufactures have been putting hyper eutectic pistions in their engines to prolong life. i understand that they are somewhat brittle. i have a 93 5.0 with headers msd ignition bigger injectors and flowmaster exaust with a cai and plug wirs (8mm taylors). the internals of the engine are stock, ie no cam, forged pistions etc. my question.... with 50-100 hp boost of nos, (i was thinking the zex "smart" kit) will the added strain on the engine damage the hyper eutectic pistons or any other engine part, if the engine has no detination?

RE: nos and hyper eutectic pistons??
 

the 5.0 have forged internals right? and for sure its gonna do some damage but i wouldnt shoot a 100 shot on a stock engine very often, its gonna take a hell of a beating.. change your cams,rockers, heads bore your cylnders, you know basic stuff so that you put less wear and tare on your vehicle for the future...

RE: nos and hyper eutectic pistons??
 

it'll be fine. i know guys running 150 plus shots on completly stock engines and it doesnt do anything. you just gotta know what you're doing with it.

RE: nos and hyper eutectic pistons??
 

^^yep if its tuned right u will be fine

RE: nos and hyper eutectic pistons??
 

you all are fast at replies. thanks but still getting mixed signals about nos. as anyone with a half of a brain stem knows, there is going to be more wear and tear on an engine that has nos. so im aware of some of the risks, just did not know with the stock 50 engine.

what kind of a car was your friend running 150 hp stock engine?

im not looking to "track it" all day long, or even run it hard much. i do have plans of getting a gt-40 crate motor some time in the future so im not REALLY concerned with prolonged relaiability... but im not in a hurry to drop a new engine in either.

talk to rsw007 about nitrous on a stock motor.

RE: nos and hyper eutectic pistons??
 

he runs 11's on a stock 5.0 motor with 150 shot and gears

hes automatic too

i doubt hes even spent over a grand on his car and he makes some LOW passes at the track

RE: nos and hyper eutectic pistons??
 

im pretty sure its a 110 shot.

RE: nos and hyper eutectic pistons??
 

he was runnin a 92 GT with the 150 shot.

if you're just gonna use it every once in a while you'll be more than fine. if anything, the nos will seal your piston rings better and restore your compression.

RE: nos and hyper eutectic pistons??
 

how do you figure it will restore compression and make the piston rings seal better?

RE: nos and hyper eutectic pistons??
 

Why the **** do you come on here and ask questions about something you don't know about, then when people give you answers you start doubting them... If the car is tuned for nitrous it won't hurt it... Try a google, E-mail a nitrous company, but dont come on here calling it nos, NOS is a company, you want a Zex kit, it's called Nitrous.... Anyway, Retard the timing 2 degrees for every 25hp, add some fuel pressure, and enjoy your new found power...

Guys,

The 92 that running the 110 or 150 or what ever it is , has stock FORGED internals. In 1993 Ford began using HyperUcraptic pistons so the original poster and myself have Hypereutetic pistions. I would run no more that a 75 shot on the stock 93 and above lower end. This is probably a little conservative, but no one wants to send a rod through the block. If you do add the 75 shot make sure you have the fuel system to support it ie. fuel pump, adjustable regulator etc. That will really help keep you from going lean.

On another note:

THANK YOU!!!

That stupid "fast and the Furious" movie got all these guys calling it "NOS"pronounced NAUSS. That is a brand, Nitrous Oxide Systems owned by Holly. The ZeX kits, Nitrous Express kits and the NOS kits pronounced N- O- S.

RE: nos and hyper eutectic pistons??
 

just to clarify for everyone saying "Forged Internals" Ford uses cast crank and rod, the only difference was a forged piston or the hyper. They used a hyper piston as you can run a much tighter piston to bore clearance and get alot more life out of the shortblock. You can spray 100-125 on ANY production 302 ford has made in the last 2 decades easily

RE: nos and hyper eutectic pistons??
 

sorry about the term gentle men (nos as opposed to zex), didnt mean to make people mad. the reason why im on here is becasue i dont know much about the cars or products and was trying to do a bit of research on different things... and i was not doubting his knowledge about weather or not the pistion rings will seal and compression will be boosted, i was simply questioning him so that maybe he would explain it. thats why im here... to learn. not everyone starts off knowing everything.

RE: nos and hyper eutectic pistons??
 

i do appreciate the help fellas, thanks for the replies.

I bought a 1987 5.0 LX Coupe used in 1989 with 40,000 miles. With a couple of bolt-ons, 3.27 gears (up from 2.73's), Flowmasters, and 150hp shot of NOS (the NOS brand kit with a secondary in line fuel pump) I ran consistent 12.40's @ 112mph at the track, and raced every weekend at the "street races" near the Philly airport and stadium areas. I did this for 4 years until I traded the car in with 75,000 miles on a new 1993 SVT Cobra. The only damage I ever did to the car was I blew out 3rd gear and Reverse, during a race. I think it happened because I was so far out in front of the other car in 3rd, I lifted my foot off the throttle, and I guess too much torque rebounded off of the gear. It was fixed under warranty - I took the bottle out of the trunk, swapped my cheaters off of the back and put on the regular tires, and the tranny shop manager left the car up on the lift for the inspector, and they never noticed a thing.

I put a 9lb Powerdyne blower on the Cobra, along with an entire exhaust sytem and booster fuel pump, and that ran consistent 12.20's on the same cheaters, 12.7 on the Gatorbacks, both trap speeds in the 113-114mph range. No problems with this car until I sold it in 1999 when my wife got pregnant.........

Anyway, my point is that as far as I'm concerned, those 5.0 engines are pretty much bullet proof up to about 500hp or so. If you treat them right, they will treat you right. By treating them right, I'm suggesting you keep the fluids fresh, and think about using synthetic fluids anywhere you can (I used Mobil 1 back then), and make sure you pump up the fuel pressure, retard the timing, and use colder plugs with power adders. If you hear ANY detonation (aka knocking & pinging), you need to change somehting. If you follow those simple rules, you should very few problems.
