And I'm still wondering if they're just trying to throw around tech terms, but is there such thing as danger to the intake manifold when using too much nitrous? I don't see how this is possible, but then again, I've never used nitrous.

It would seem to me that all the pressure would be on the cylinders and pistons, and the intake would be a distant concern. Please enlighten me on this if anybody knows better. Thanks!

sure it could happen, fire with the intake valve open would light the intake, it happens with pro mods, t/s car, and nitro cars that's why lot of them have burst plates. never saw the movie so i don't know the contex it was said or meant.

"surprised you didn't blow the welds off the intake"

you referring to that statement? First of all, there is no welding on the intake and second......you wouldn't blow the manifold anywhere. Usually the nitrous backfire happens in the intake manifold and it "burps" it way back up through the carb or intake tubing

Believe it or not, the Eclipse in the movie DID have a welded intake! It was NOT a turbocharged engine, but did have a sheetmetal intake. The engine is the non-turbo version 2.0L Chrysler 420A, like the ones used in Dodge Neons...:lala:

There was a pic I saw a while back, either on this board, or the Theoretical Racing board, of a ZR1 plenum that was blown apart. I'm pretty sure it was from a wet flow n2o system.

ATOMonkey

Too much N20 loads up the manifold and because the cylinders don't evac completely hot gas can flow back into the manifold and light the nitrous and fuel. This also happens real bad when people use nitrous on manuals and lift during shifting w/o a good management system. When they lift the juice is still on and when they mash it again more juice flows in.

That eclipse was just an over zealous Neon.

Tell that to this Pro Mod racer

It was, I also read what the owner said about when it blew up. it sounded to me like a self inflicted wound to me.

one thing that can get you a wonderfull Nitrous backfire is trying to hit it when the R's are down & the load is up (like on launch). its all about momentum, you want it IN the holes not in the plenum.

I dunno about the intake manifold blowing up, but what about the exhaust manifolds??? from what the movie looked like, something blew out from under the car??? i have no idea just throwing out an idea.

Also, it seems like the eclipse in the movie WAS turbocharged. In the beginning, when he is racing it in the parking lot, there is definitely a wastegate sound when he is shifting, they also mention a "T4 Turbo" when "jesse" is looking under the hood right before the first race with dominic. Sorry, but I've seen the movie a bunch of times. The ACTUAL car may not have been turbocharged, but in the movie, it was portrayed to be.

I think that we have to differntiate here between real life (the ZR1 & the Pro Mod motor) & fantasy (The Farce & Furry-ous).

My question was always "what made that floor plate break loose?" forget blowing the intake and any of that, but what about nitrous could break that? Especially since that part of the car isn't a bolt on as I recall. There was a good article in car craft a few months back about the top 10 stupidest lines from that movie, was quite amusing, the guys at the shop and I laughed for hours.

Yes it was a ZR1, the wet system backfired, and ripped the top of the plenum open. this was a solid cast piece torn open like can of soup.

Y body bill

Absolutly nothing!
It was all there to create some sort of action/tension.
It was used to shoot sparks everywhere, basically eye candy. I am suprised most ricers dont have removeable floor boards yet... well maybe they do, I stay away from that croud.

Then I think that piece of floorboard flying away was suppose to give some indication to the person watching, that these cars were (suppose to be) going reall really fast. Just some guys who make movies, sitting around, thinking dumb stuff up to put into a movie to make it look cool to those less educated about car stuff..

Without flying floorboards, blowing bolts, laptop controlled NOS systems, turbo boost buttons (just like video games), blurry vision, fire breathing exhuast pipes, and 'motec systems exshaust', it would look like the 15 second cars they were? LOL!

83TransAm

Hey!!!! I don't have a TURBO boost button, but I do have Nitrous boost button!!!

(Noticed how I call it nitrous, and not NOS. It doesn't matter what's ON the bottle, it's what's IN the bottle that counts).

Lol, just thought I'd share that.

Yes a nitrous backfire can blow an intake apart. Ive have seen it first hand in a buddies mustang. He hit a nos wet system under 3000rpm and blew a cast aluminum trickflow intake in to 4 large pieces. It was nuts ive never seen or heard anything like it. The funny thing about it is that he is the only 5.0 guy around that didnt have to pay a penny for the four inch cowl in his hood

lankchevy_350

but u gotta love the eclipes or supra or whatever(i didnt pay to much attention to the ricers, i was to busy laughing) that beats the blown, tire wrinkling, slick wearin, 440? powered, charger! at that point my friends though i was going into some weird form of shock cause i was laughing so hard! in real life that little orange pos wouldnt have lasted 3 seconds with that charger even off the line, i guess the producer of the slow and the curious had no idea whatever what torque is. i dont care how many bottles of nitrous u put into that little thing it would still be no comp whatever in any type of race. hmm i also wonder if they realize that it doesnt matter how many bottles of naawwwsss u have. all that has to do with is how long u can push the button. they acted like if u had two bottles of naawws then it gave u twice as much power as one did. dominc did have one trick naawws setup tho. could u accualy buy stuff to put it in the seat? hmm o well. my rice friends get mad when i call it slow and the curious so i do all the time. they worship that movie. i think one of them goes home and watches it all the time

What's wrong with laptop controlled NOS? I'm have it, and hope to be installed soon.

83TransAm

Yes you can actually buy those bottles for under the seat. My girlfriends brother has 3 of them and he got the outsides chromed. They look sweet. BTW he has probably the sweetest Grand Prix GTX you have ever seen!!! I'll get some pictures from him. Run's 13.6 with two subs in the back. Not bad!

my favorite part is when dominic says "you're lucky that hundred shot of naws didn't blow the welds on your intake manifold." HUNDRED SHOT?!?!?!?! on a friggin "race car" a 100 shot will fu(k it up? my quad has a hundred shot! but his eclipse can't handle it? our cars can handle 150 stock! ricers are such junk...

Y body bill

Actually nothing, asuming you dont have to make some adjustments in the middle of your 10 second pass as it gives you intake warning messages. LOL...

Did you see the movie?

So know I am wondering what exactly you are going to use the lap to do do for you? Just activate the N2O? Staged setup?

Y body bill

I think it is clear that they needed to fire the guy responsable for the technical smack talk in that movie.

i didn't know the eclipse had a sheetmetal intake smartass

Ok I see this type of thread open up all the time on a lot of the forums I visit.

The main point you all have to realize is that the movie was not made for everybody to nitpick and see what was faster or slower...

The Movie was made for pure entertainment, The technical aspect of it is pretty bad, comments like MoTeC exhaust sytems, or Sneeky pete systems in seats, or Camshafts in RX-7's (this is one a lot of folks don't see) but overall it was made for entertainment. You don't see us all tearing apart a X-wing fighter, or that a light saber can melt through a 4 foot thick steel wall. These are movies folks, and yes they have some falicies, but if you look at the overall premise of the movie, its the only thing the domestic guys have to laugh about as far as a "***** movie"

As far as a 100 shot on a 4cyl, in N/A form, yeah no big deal, but in a turbocharged application you have to realize the combustion pressures and what an added 100 shot will do in it. Some of the information in the movie is a little far fetched, but some of it is based on acctual systems, just glamorized by the movie.

If you were to ever look into some of the high dollar stand alone engine managaement systems such as Electromotive or MoTeC you wll get the 3D grafic the same as shown in the movie

But lets look at the money the movie made for perfromance shops and Nitrous Oxide Systems. Honda kits went to immediate back order for 6 months after the initial release of the movie. Cars depicted in the Movie skyrocketed in price, and the beast was awaken. Now I am not saying that every Civic with a Type R sticker on it is gonna run 9's, but there is a lot of technology that a lot of the "Domestic" guys just don't understand. All you have to do is look at the amount of forum topics in this forum alone. There are a multitude of other forums devoted to other brands of cars. The Imports may not be the fasteset thing in NHRA or IHRA, but they are starting to show what can be done, and the kids are acctually learning the power curve a little faster than most of us. The Technology is there, its all in how you use it my friends.

The Fat and the furiest has about as much to do with real world cars as any of the Star Wars movies has to do with our current space program (NASA). :lala: :lala: :lala: :lala: :lala: :lala: :lala:

That being said, there is no way that just flowing large (even ridiculaous) volumes of nitrous through an intake will overpressurize it or harm it in any way, but a nitrous backfire is another story.
enough nitrous to tear the car in two?, yea right, and A rear wheel drive car that can do a wheel stand and be smoking the back tires to h3ll at the same time?, sure, why not?!
They had no intention of making an accurate documentory, just an action flic that sold lots of tickets.

Yea I will just be using it to have the stages setup to come on instead of buying a NOS mastermind or jacobs box.

Alright you want to talk about the dumb & the wingbearers go to their board.
lol

Im closing this.
