How Much Nitrous Can The Stock Pistons Handle?

-
Getting the most power from a particular combination I think takes the most skill and knowledge. Bolting on the bottle makes fast power for sure but it's something that anyone can do. Look at the power those guys get from their pure stock drag racing cars
 
Sneaky Pete for that last 10th when he thinks he has you.

do you have even the slightest idea of the time, money, R&D, money, skill, money and testing and money that people have put into those combinations?

a hundy shot of laughing gas starts to looking mighty tempting when you start thinking about it.
 
Getting power from whatever source takes knowledge and talent. Nevermind the $'s...

NA, N2O, snails, blowers... doesn't matter. To get the best out of any combo takes WORK!

My favorite is the make sure you run the nitrous rich on fuel crowd. That's a great way to destroy an engine, pound the snot out of the ring lands and torch pistons.... but, they saw it somewhere 30 years ago or heard it from someone that smoked an engine back in the day. When we were burning plug straps in the 80's, even the manufacturers said fatten in up. We learned that was the wrong thing to do after some time, testing and $.

No Dan doesn't not know. He talks out his ***.
He has no idea about some subjects he talks about. That plan of attacking more power is.
You get your tune sorted out. Then dial back timing manualy or with a box. And put tha gas to it. getting the best yiu can out of what you have then putting a power adder in place.
(Simply put) Go as far as combo goes then add the gas. Who in their right mind would put it on a poorly tuned engine.......

I know it is, and I realize the money those cars have invested,
 
Most 50 shots are dry shots. That means with no extra fuel. I've never recommended or liked those. IMO, stock factory cast pistons are good to a 150 shot, as long as there is added fuel as well AND it's run "a little" on the fat side. Not 450 pound fat woman fat, but "a little" fat. The excess heat is what makes things get sketchy. Rings can but together, piston tops can get speckled and eventually burned. If there's extra fuel there, you can usually keep bad things from happening. I know some Fox Mustang guys who ran 500 plus pro shot foggers on stone stock 5.0 bottom ends......but those also came with forged pistons from the factory, too. I know one guy still running his original 175K short block and it's been through nitrous and more than a few supercharged top ends and it's still running. He's run a best of "somewhere" in the ten ohs with a 100% stock short block, not including the cam and last I talked to him, the car still runs fine. He's "detuned" it to street car service nowadays. He's always said the #1 biggest mistake is people run them too lean trying to pick up that last little but and he's never cared "about that".
 
I have about the same combo but in a 360; stock crank, rods and pistons; with hastings rings gapped to their 250+ shot spec. As long as you keep detonation away and don't butt ring gaps together I don't see why you couldn't safely run over 100 shot.
The head gaskets are a concern, but as long as you back the timing off enough and progress the nitrous into it slowly, they should live long enough to have some fun and learn a little bit.
Also, I am going to run e85 in mine, just as a little safety net due to the cast pistons. Pump gas on nitrous isn't the best idea for stock engines.
Wow, that's more than I expected. Maybe my next motor will be a cheap stock-ish beater with just rings opened up more, or maybe something something built to handle abuse, it depends on funding and time.

As for my current motor, I've put too much effort into it to blow it up. From the ring size calculations, a 50hp shot should be ok. I assume because while I don't remember the exact ring gap measurements, I do remember that they were at the large end of the spec, like .020" or so. I figured that would be fine for a hotter street engine and even though I was told it should be tighter, but Installed them anyway.

Of course there is the curiosity of how much can the stock junk handle, with proper ring gaps and a proper tune. :p

Well, since they are supposed to be as from the factory there shouldn't be much R&D involved, money, that would be mostly on the machine shop work as the cam, heads, intake and exhaust manifolds have to be stock. You can dial in the carburetor and the distributor. There's no porting allowed or any form of a competition valve job. Pistons can be aftermarket as the compression ratio can be 1.5 points higher than stock, valve train has to be stock. I talked to a guy who said that the cost wasn't much more than a stock rebuild

yeah, sure.

sure dan. i can't decide if you're incredibly naive or just ignorant.

can i interest you in this bridge i have for sale? it's only $22,500 but i'll make you a deal.

They spend money on a few HP gained here and a few there. It ads up. And the last of the HPs really cost.
The FAST Guys have to stay within confines. Please don't confuse confines with confusion.
Just because you are confused

You don't have a clue about some things you talk about. So when you post it becomes evident
 
While my internals are all forged and built for nitrous, I highly recommend the Holley Super Sniper system to manage it.

I have a Dry two stage Nitrous Express kit for up to a 1000 shot.

The Sniper allows you to control everything…timing, fuel, delays, progressive, what rpm and throttle position is required to spray and what rpm to stop.

There are also safety cutoffs for AFR etc

I run 100hp shots in both stages…total 200hp. When I activate both stages it’s a kick in the pants.

All that to say if I was running on a stock engine I’d want the precise controls that the Sniper system provides.
 
I run a 100 shot on my 408. Run 91 pump gas with a stand alone fuel system for the no2. 1 gal. Fuel cell is filled with vp 110. About 450 hp without the nitrous.
 
Great, just great. My my thread asking for knowledge and experience has turned into a "Dan vs. Everyone Else" argument thread. I try to learn from my mistakes, but it seems like nobody else does.

They like to believe that they know everything. I've done lots of research on how they build those pure stock drag racing cars and the engine does cost a little more than a normal rebuild but only because of the extra machine shop work they have done. Remember, the cylinder heads, intake, exhaust manifolds and cam have to be the same year as the make and model and rated horsepower. The only aftermarket parts allowed are the pistons, if you don't believe me look it up as I have several times, I'm not talking about stock eliminator racing either

If people would just not engage him, that would do it. I think he needs another vacation. @toolmanmike ?

yeah. sure. you keep telling yourself that.
 
you don't have the slightest idea. not even a hint, a whisper.

click your heels together and keep saying that danny boy.
How much do you think that it cost to build a engine that's pretty much 100% stock? I'm not trying to argue with you about it. Remember, they have to be as they left the factory except for the pistons. No roller rockers, no headers, no light weight rod's, or crankshaft. Research it out as I have, heck even the carburetor and the ignition has to be factory as does the air cleaner housing. Now you still think that I don't know what I'm talking about? I respect your education and experience and I would appreciate a little support instead of all of the negativity
 
Ignorance is bliss. Unfortunately you sometimes have to sift through the trash.

OP got some answers. It all comes down to how hard do you want to push it. I'd run a 100 shot on a stock engine all day long
