Is N2O considered Foced Induction?

Hey guys,

I know this is a stupid question. But I got this kid that works with who just annoys the shit out of everyone with his POS Mitsubishi Turbo eclipse. I don't know what year it is but it's the older body style.. wanna say "rs"? Not sure. Anyway.. swear this kid thinks his car is as fast as a Lamborghini... he was telling me that he smoked a Ram Air Trans AM from a roll the other day????? By the way, the kids car is BONE stock. He's telling me that his car can handle like 18psi? Is that true... or another bullshit story. He also tells me he won't race me because I have NOS, so I told him that's like telling you to take your turbo off! He tells me that N2O is not considered Forced Induction??? If N2o compresses the air doesn't that "Force" more air into the intake??? He's also making comments like " oh it's still just a Honda!" wait a sec........Mitsubishi!?!? Where do they rank as far as reliable cars?? Any of you guys have any sites with specs like a cosumer report or something? I just want to print some shit and duck tape to his freakin windshield! Not to mention my interior was worth more then he paid for that whole car! Help me out.....

Yes, N20 is considered forced induction...

An RS wouldn't be a turbo. But if it is turbo then it has 195 HP, which isn't slow. They are not reliable whatsoever, they are pieces of crap.

N20 does not ''compress'' air. All N20 is is a higher concentration of oxygen than the normal atmosphere so if you add more gas it gives you more power.

Ok.. got it! and like I said didn't know if it was "rs" or not but it's the one you just said with the 195hp. Yeah, it's pretty quick.. but he's telling me he can boost up to like 18psi?? Is that true... and most of all.... is NOS considered FI just like a turbo?

Yes N2O is forced induction......i would not say however that those car's are pos'es unless treated like crap....if you take care of them and mod them you can get some insane power out of those 4G63 engines

Yes, N2o is FI. n2o is compressed gas. Therefore already compressed. It is 33% oxygen when released it causes an endothermic (cooling effect) reaction, and cools the intake charge while it feeds the engine with compressed oxygen.

PS: DSM's are very reliable, yes they can hold 18psi on race test fuel. The bottom ends from 1g dsm's can hold ~450whp. They are beast.
He's a moron for saying n2o is not FI.
Ive repeatedly watched DSM's reliably walk into 13.7's with 500 bucks in mods.

18 PSI is probably doable with a bigger intercooler. I don't know if the stock turbo can put out that much either. 16 PSI no problem. I think they boost 12 PSI stock, so 18 probably isn't out of reach.

Hmmmmmm....

Interesting! I didn't believe him when he told me that if he put intake and exhaust on his car he would smoke me even with the NOS? But maybe he's right! I really don't hate the car.. I hate the fact that this kid thinks his car is the best thing since sliced bread and whipped butter. But stock is stock... he aint' got shit on me.... cause mine's so peeeeerrrrrrrrrttttyyyyyyyyyyyy!!!!! :finger: Thanks guys! good shit though!

How much power do you think you are putting to the ground? OR at the crank? His car weighs a lot more.

Intake an exhaust do shit for a DSM.

Tell his stupid ass to get a boost controller, and larger injectors, run open down pipe and get a real boost guage.

Explain to him 18psi, 550cc injectors, and an SAFC will get him speed.

Next step from there would be a sidemount MK4 Supra IC and a larger turbo.
He'll be well into 12 sec ET's, btw if he's AWD, stock he may beat you. Depends on your motor and setup.

I'd be one of those ignorant idiots if I made up some number because I never got my car dyno'd so I really can't tell you. The car pulls ALOT more then it did when it was stock naturally and with the 65shot of N2o it makes people turn their heads with the "what the hell" look. But I mean it's no monster by any means! I'm gonna do the H22 swap next March and work that with cams, port and polish and the mods I have done to it now. Like to get in the 250-260 range before the NOS... but that's then....

and ya.. he'll beat me stock because he does have AWD and the fucker power brakes his car to get the turbo spooling.. in his..........AUTOMATIC!!!!!! (I) <-----------pussy!

So it's a GSX if it's AWD. Auto? What a POS. Cheater. What was your car stock, like 125?

Yeah.. mine was ony 145 stock (ex vtec)... and my question to him was.. what is your engine stock with no turbo?? maybe 110-120??? Just really bugs me.. the fact that he thinks Mitsubishi's are better cars then Hondas! Can't wait to get that H22 and put some internals in... he always talking shit but couldn't even afford to put one of the chrome exhaust tips on that you buy at discount auto....and when I asked him to take it to the track on friday.. OF COURSE!! he said no.... said racing me would be a waste of his gas!........idiot!

Actually the N/A Eclipses are 135 HP. Yeah thats sad, does this kid even have a job? If so what does he do with the money? He must blow it on the crack he's smokin if he thinks he can beat you - HAHA - LOL:D

The 4g63(turbo DSM) motors are different from the N/A motors. They have super low compression and are beefy inside. They can handle alot of abuse. They were made for boost and lots of it. Great motors if you ask me.

Mr Anderson: The SOHC VTEC motors only make 125-127 to the flywheel, which comes out to about 108 to the wheels. The eclipses make around 160-170. Even tho they're heavier, the power to weight ratio is supierior.

Whats super low to you? Isn't it 8.5:1? I know the engine can handle the boost but I'm wondering if the stock turbo can put it out. That stock turbo is awfully small, the stock one in my Daytona is bigger I'm pretty sure. I don't know, how does a Garret T3 measure up compared to the Mitsu T25?

Cronic... I always thought that the VTEC came with 145hp? to the wheels? Not really sure...... but on the lx without the vtec came with 130hp according to Honda specs. Didn't take time to research much.. but did find this link (http://www.automotivesite.com/1996_Honda_Accord_LX.html) ! Scroll down to where it says "RIDE AND DRIVE". And don't get me wrong.. I know that car can handle ALOT more boost then a F22 or even a H22... but my point of topic was, he won't race me because he says NOS is not a form of FI and it would be a waste of his gas! So I wanted to hear what you guys considered N20 to be??? Would you agree with everyone else by saying it is!?!?!?!?

ah yes the ever great mitsu motors. the dsm's have stong motors. it is know as the buletproof motor to most import nuts. They are capable of substantial horsepower gains with minimal mods. but that was already stated. and yes with little to know mods you can boost 18 psi stock. my friend has had 3 eclipses and 1 talon. on all 4 of them he had boost controllers be in manual ones or not, but they all boosted anywhere from 18-22 psi when he turned it up. Makes you wonder why didn't honda ever build motors like this huh? Well all in all the turbo mitsu motors are bulletproof and can handle lots of power and are far better then honda motors, now if only they kept running like honda motors right boys!!!!!!!!!!!!

Woops. My fault. I was speaking of Civic Ex VTEC motors. I didn't know you had an accord. You are right sir. 145bhp (crank). With n2o you should be able to give him a good run.

The kid can boost the stock 4g63 with the t-25 to 18psi, if he wants to roast his turbo. The t-toosmall is only effcient to 16psi, after that, your just killing it. The 4g63 is beefy enough from the factory. as if it is properly tuned, the bottom end can handle over 400whp. So go school this kid with your newfound knowledge, i know i would. Also, the compression on the first gens (90-94) is 8:5:1, on the second gens(95-99) it is 9:5:1, which is why many 1gens run 2nd pistons. Also, a garrett t3 would whip the t-"too-smalls" ass anyday. You aren't supposed to boost the t-25 past 16psi, unless you are rich and have money for replacement turbos ever 10k miles.

I forgot to add something, the 1st gens had a 14b turbo, which was larger and good enough for 250whp. That is why you see many 2nd gens with the 14b turbo. Many believe that Mitsu made the turbo swap under the guise of lower production costs, while the "offical" mitsy reason was "not as much turbo lag", well id much rather have a little bit more turbo lag, and more power, than instant reponse and less power. Anyone agree?

CR on a 94 dsm is 7.8:1, your right about 95+'s using the 1g pistons.
CR on a 95+ is 8.5:1.

Alot of guys who want good midrange, and explosive top end power go with the larger t3/t4 or 20g turbo's and 9 or 10:1 compression.
With this high of compression however, boost is limited to tuning and race gas above 11-12psi.

yeah with your 65 shot you should give him a run for his money. his car is heavier than yours and you guys will have about the same power. but i would assume you have the advantage cuz you have a 5 speed am i correct? and he would have a 4 speed auto so it would have long gearing.

Everything I have been reading tells me that 1st gen is 8:5:1, and 2nd gen is 9:5:1. maybe i have been reading the wrong shit, but that just sounds too damn low to me

I don't believe any factory Eclipse turbo was more than 8.5:1. The non-turbo is 9.5 I believe, maybe thats what you've been seeing.

Huge difference! A T25 spools up very quickly but runs out of boost just as fast. The T03 takes a bit longer to spool but is capable of much higher boost levels an will have good top end.

Does anyone know the max boost you could get on average from a T03? Or how about the new GT03?

liquid8 is right. I was getting the engines confused.

I know the T25 you can only get 16 without frying the turbo. I think you can get about 20-24PSI from a T3, somewhere around there.

My t3 pushes ~17 before it just shits on itself. Ive seen it goto 20 on spikes before. 40 trim. There are several t3's our there. Fortunatly It's not so much the PSI that gives hp, it's the CFM | lbs./min.

Bigger is always better ladies and gents. To a point. ;)

If you have a 5sp in the accord I think you will take him b/c of him having an auto tranny. However he will have a good launch compared to you even though you have a manual tranny, but race him from a rolling start and whip him good b/c it being an auto and having awd is going to eat up alot of his power. IMO AWD is only good for racing on twisty roads or tracks and dead stop drag racing.
