Location for nitrous

he said he kept turning it up and had it at 19 psi for 6 months before pistons 5 and 6 melted

I ran 28psi and 180 shot on stock Nissan cast aluminum pistons. The car dyno'd almost 700horsepower. Everyone said the limit of stock Nissan pistons was 500ish hp. Well I proved them wrong right up to the point where it melted a piston. Saying that a car held 19psi for 6 months before it blew up is a moot point. It still blew up, and not ever NA car with a turbo on it will hold that kind of boost for that long.

there is no reason you shouldnt pull timing out you are right which i plan on doing, i have only have done 2 pulls with stock timing and what not no more because i dont want to re open my already built motor.

In post 22, you say that you are running stock timing. Now you say there is no reason you shouldn't pull timing and that you are going to because you dont want to re-open your already built motor. So you know that spraying a car without pulling timing is asking for holed pistons but yet you do it anyway. Thats being stupid.

the stock motor EVERYTHING, will hold a 50 or 75 shot all day long with about 2 degrees of timing taken out i just decided to have some fun and push the limits because i am not afraid of what may happen, but because i know my car, motor, and spray.

Everything huh? Want to see a blown apart intake and a melted number 3 piston from a 2006 Chevy Cobalt with under 10,000 miles on it. It came out of a car that was spraying a 50 shot wet kit.

there is absolutly no reason what so ever why i cant spray a 150 or more through a single fogger, v8's do it all day long (which our motor isnt far off with turbo and a v8 like stroke) as well as some 4/6 cylinder, just because you wont do it doesnt mean other people wont if they havent already.

Yes there are reasons why you shouldn't spray a 150 shot through a single fogger nozzle. Carb'd V8's use spray bars/plates between the carb/intake which are capable of flowing significantly more nitrous/fuel then foggers are. And the fuel injected V8's that spray that much are usually using more then 1 nozzle (look at kits for F-bodys/Corvettes). A V8 with 8 fogger nozzles at 150hp each would be flowing 1200hp out of a single stage?!!! Where do you get the idea that we have V8 like stroke? A 283 Chevy small block has a 3.00" stroke and a 2006 LS7 has a 4.00" stroke....So what exactly is a V8 like stroke and how does it have any effect on nitrous what-so-ever? BTW a 7m-GTE has 3.58" stroke (and for arguments sake a Nissan VG30ET (like my 300ZX has) has a 3.27" stroke).

btw the none super charger cobra's wont hold a 200shot of spray nor will a stock ls2/lt1, believe me i have more than plenty of friends with those cars that blew their motors because they got bold a sprayed above a 100/150 shot.

And I can show you a 1999 Cobra running a big shot that still runs just fine, right along with LS1/LS2 that shoot just as much. I've seen 89 Ford Probes take a 250 shot and run great, and cobalts take a 50 shot and vent their crankcases. A number cannot be put on what any one particular engine family will hold. BTW here's a video of a 8.5/1 compression 2 bolt main truck engine (that came with an amazing 189 whp) with Edelbrock aluminum heads, 1.6 rollers, a nitrous cam and a direct port kit making 472whp on stock internals, and after that pass we open a nitrous bottle up straight over the carb for 521whp. Thats a 332whp increase on factory cast pistons and she still ran great afterwards.

I am running my fogger nozzle in as close to the TB as possible. This allows the mixture to go directly into the engine and avoids the gasoline "puddling" problems associated with the fogger being further away.

ZFAST300Z, look man im not going to argue with you ok, ive done it and would do it again.
be affraid of nitrous or dont be but dont try and teach me about something i know about and have done and done it with success, nitrous doesnt blow a motor, idiots with nitrous do or a improper set up does. . . dont jump down my throat because i dared to do something.

btw, i know a lt1, ls1, ls2 and some 96-99 cobras can hold big shot (200+) but for only so long(maybe 3-4 passes depending on the life of the motor), its not recomended to run above a 150shot.

thank you

p.s.
yes a stock supra turbo motor with everything stock in good condition will hold a 50/75 shot no problem what so ever.

I had a freshly built stock 7mgt, with 16psi, take a 200hp shot reliably. However, I had to cut a piece of the cam sensor ear off so that I could turn timing back far enough for the engine to take it without spark knocking. But man, that was a ride!!!

 

[Alpinesupra]

well if anyone has any helpful pictures, i am trying to swap from a push button to a wot switch but i cant seem to figure out where to mount the switch with our linkage set up.

You can tie into the TPS signal as well. That would probably be the easiest way if you want a WOT switch. Otherwise, I would just run a push button.

 

[Bigdough666]

A friend of mine ran a 250 shot on his Trans Am DAILY for YEARS, went through about a bottle a week, never had any problems aside from traction.

Its all about how you set it up. Do it safely, use a WOT switch, window switch, fuel pressure relay, etc, etc, and you have nothing to worry about as long as your engine is healthy.

the tps sensor kit costs about 200 bucks which i do not have right now, i have the push button now, but can not find a good way to mount it with the braket the its on so im gonna have to fashion up a new bracket. . .

ok this thread is a lil old but ill ask my questions here before i created another similar one. I think we all agree that a 7mge can take a 50shot - 75 shot on a stock motor. What about the stock fuel system? Is the injectors and fuel pump from the factory flow able to supply enough fuel for the juice without going lean. I'm installing a dry kit in about a week when ever it comes which uses the fuel pressure regulator to increase the flow when juicing. Lastly anybody in the NYC, NJ area that wouldnt mind looking over the kit to make sure everything is set up? I wont mind the drive.

goodness, how much timing were you pulling?
