50 hp dry shot

[justhavnfun]

oh also, installing the nos kit on its own wont yield best results.

Think about it, you are adding more oxygen and fuel....that means a larger combustion and more exhaust gas. They don't call it chemical supercharging for nothing.

My point is, it will potentially increase engine heat, and will increase the need for an upgraded exhaust system. Not sure how far the stock system will flow to, but i doubt its going to flow fantastically with boost AND nos. I'd still be looking at a full turbo back exhaust system before going down this route.

when mazda ever gets around to making the exhaust available without a doubt i will be upgrading. i think the exhaust and cai is overated though. i was reading a article (can't remember which publication) but they tested a
ms3 with mazda's exhaust upgrade and their cai and a stock ms3. they did say there was a noticable differance but they didn't think it produced the hp mazda claimed it produced.

Ok lets say you can somehow get mazda to pay for the engine explosion - wouldn't it still put you out? having the car in the shop for weeks while they investigate the cause, replace the motor etc?

I still reckon wet or direct injection is BY FAR the best way to go. Beauty of it is you pay once...then when you rebuild the motor down the track to be stronger, you can wind up the NOS shot... dry systems, i think about 75 shot is as far as you can go safely before you start running into all sorts of s***.

Wet system isn't going to matter to the ecu.... it may detect slight knock and back the timing out a bit (which is what you want it to do anyway), but standard ecu sees the air at hte MAF, applies the fuel it thinks you need, and the wet system supplies the blended N2O + fuel at the required blend. Hell if AFRs are an issue, jet the fogger such that it doesn't quite add enough fuel, this will lean out the entire range but still be safe.

Seriously, for the cash saved, its not worth the heartache.... do a wet system or don't do it at all....

but whatever you chose, should make for an awesome ride

ok, thanks for the info, as far as the car being down. not a problem. this is the grocery getter. i have other vehicles. honestly i bought this car for my wife to run arrands. i didn't think it would be this fun to drive. i have a vette, 2000 ram air trans am and a 91 ferrari testarossa. (which is lucky to the road maybe four times a year) the only reason i stated dry shot was it would be easier to remove but most likely i will be putting the wet. thanks for the input!

Well from what I have seen so far a 50 shot would just about be perfect with how rich the MS3 runs. But the direct injection would really play hell with the EGT's. I would suggest clipping the exhaust wheel on the turbo if you are going to do this just so you can keep the EGT's in check. Other then that I will be running N2O as well with racing meth to keep the knock at bay. Our cars do have a knock sensor so if anything did start to go terribly wrong the ECU should pull timing due to the knock sensor readings and adjust for the N2O. I have also heard of a MS6 running a 150 shot on his car (other forum) an on the dyno they made over 440 WHP with it. There were other mods as well but that is a hell of a gain with just a shot, turbo back exhaust, TMIC, and intake. I also believe it had some sort of fuel managment as well but not 100% sure. Big easy power can be added to our cars and if used and installed correct it will make the car last just as long as if you were running without it.

clipping? i'm guessing that allows exhaust gas by the turbine lowering the egt? is there any piks available of a exhaust turbine clipped?
i plan on monitoring the egt's with a remote sensor. what is a safe egt range? and thanks for the advice by the way.

why wait for mazda?

i may be drawing a long bow but given the cars you listed that you own, and the fact that you are even CONSIDERING NOS (which will turn a car on stock internals into a grenade), i figure you're not short of a bit of green.

SO

Find an exhaust shop - if you have expensive taste, burns stainless, otherwise any exhaust shop - and get them to fabricate a turbo back system... nice big long dump pipe and a 3in behind that...

Then you can feed the motor as much air as you could possibly like and it wont hate you for it

keep us updated of your progress....would love to see a speed 3 on gas

hm...im just gonna lay back, sit down tight, get myself some popcorn and light one out.

make sure to make a video when you do this, i REALLY want to see it.

 

[justa4banger]

the 50 for my car was just fine as a dry shot. no ill effects. (had WBo2 in car)
Given the serious richness of the car from the factory i bet a 50 shot would net 75 hp at the wheels. I say try it and listen for problems. get a good shop to tune it on the dyno and have fun. I wouldn't go higher than a 50 shot since you have no control over timing (unless you have a piggyback)

I don't car what ANYONE says on the websters internet dictionary. Any given NOS kit will work fine if proper planning and proper tuning are done correctly. all the horror story you hear about are when some punk ass kid gets a new NOS kit and forgets to install the pills. "It was a dry shot and it blew my s*** up" they fail to mention they were a dumbass in the beginnning and desrve the trashed motor.

IMO NOS although COOL, is not for me. i got really tired of having to pay for the junk. i like my SVO more, just turn the boost up and hang on. the MS3 is a *quick* grocery getter, thats all

The dealer will still be able to detect NOS in your car even after you pull it all off. In addition you just posted on a public forum how you plan to do this. Not very smart. The bolt ons are the best way to go. CAI - Cat back and an upgraded IC ($550) will pretty much net the same results.

They will only investigate further if the motor comes back with a burnt valve or piston (2 known signs of Extreme LEAN condition) . Now if either of those 2 things happen then you deserve to pay for your motor as you were dumb and didn't have the motor tuned correctly.

I love all the negative feedback about Nitrous. All these horror stories, all this conspiracy theory crap. I had the bottle on my VW. 2 of the mechs i took my car to, knew it. VW still replaced it, and i had been bragging about the nitrous for almost 2 years on the net before she blew, so the fact some one MAY read this thread and try to void a warranty is garbage. On a side note bring the car in STOCK , not one mod on it to give them a clue. Hell i still had the hole in the intake tube for the nitrous nozzle and they just filled it will silicone.

get the car on a dyno, GET A WBo2 meter, try a 35 shot and run it, then a 50. Sart small and go slow, If you see problems with A/F ratio or HEAR pinging, then back the **** off. re tune and try again. ANY Motor wil take alot of abuse for a split second, its the dumbasses that STAY in it, when they don;t know what to listen for, or are tuned incorrectly.

.....Hell i still had the hole in the intake tube for the nitrous nozzle and they just filled it will silicone. .......

That mechanic should win the Darwin award.

 

[tru-boost]

FROM EXPERIENCE.....
nitrous on a turbo car will increase spool up and max boost.
in the case of the MS3 i am willing to bet that this would cause you to hit fuel cut from overboosting. and do you know what happens to an engine that is sprayin nitrous and the fuel gets cut ?? BOOOOMMM !
dont do it. you have a turbo, add bolt ons and wait for thr cobb tuner !!

you really think that a exhaust upgrade and a cai will net the same results of a 50 shot nos?! you've got to be kidding! and just how will a dealer know that i ran nos? they may suspect i had altered something but proof is needed to deny a warranty claim. as far as posting on a public forum. who am i? do you know? no. my name and who i am is no where on this site. hey maybe the dealership will get a warrant and seize my computer. then CSI crime labs can access my hard drive and read my posts on mazda forums. then they'd have proof that my ms3 was tampered with. lighten up man!

 

[justhavnfun]

ok look, lets just settle something now. i don't care about warranty. if i blow the damn thing up and mazda proves i had nos and denys the warranty. so be it. i'll rebuild the bottom end (and top) depending on how much damage i do and learn from my mistakes. i have never just slapped something on my cars willy nilly without doing my homework. nos is doable if done responsibly. it does have a bad reputation as one writer stated from kids buying the kits and overjuicing engines. it is addicting.one writter posted to start small and ramp up to 50 hp. excellent advice and i would be foolish not to. 35 nozzle, 50 nozzle, and if everythings running smooth have some fun. so please, anyone posting how its a bad idea because i might blow my engine and mazda may not replace it. i got it. i'm more interested in any info that would be helpful to making this work.a buddy of mine who runs extreme tunes on his ford turbo truck said that he read nos actually cools egt's on diesels.anyone know anything about this and why i've been told on here that the nos might raise my egt's to dangerous levels? just curious. i still plan on monitoring egt's remotely. thanks

thanks for the reply, actually from what i've been reading on the ms3's bottom end. it seems to be built to to take quite abit of punishment. steel crank, forged rods, and i'm assuming forged pistons but i haven't confirmed that yet. i would be suprised if they weren't. if what i've been reading from mazda is correct, this bottom end could easily take 350-400 rwhp. thats not my estimate but of 3 tuner publications. mazda is running this engine very conservative. obviously for reliablility. 50 hp nos really isn't very much juice. 35 and the 50 are entry level kits for usually stock cars. i know when i fabricated a b&m supercharger for a pontiac 455 engine. i had to overdrive the blower beyond the recomments levels. i called b&m and spoke to their engineering dept and they told me the blower's recommended rpm was really only at 60% of the rotors capacity. i could still overdrive it another 20% safely without rotor distortion and destroying my whole top end. i was able to push 10 lbs of boost out of that little 174 cc blower on a 455 cid. so i guess my point is that mazda isn't going to build a 265 hp turbo short block at 90-100% capacity. it wouldn't be reliable. i would guess it's running at
60%. which means this engine has alot of potential if harnessed properly. and i think i'll wait on the exhaust from mazda. trust me, there's no substitute for a gig-mandrel bent exhaust.

 

[LordWorm]

dude mazda are not the only ppl who will mandrel bend you an exhaust system... and i'd take a burns stainless exhaust over a mazdaspeed exhaust any day of the week.

i've been building cars for 22 yrs i think thats obvious. i know the speed shop down the street will bend me up a stainless exhaust for three times what a gig-mandrel bent exhaust would cost. there is a difference. why do you think companys like borla, magnaflow,and flowmaster are so successful? these companies flowbench and computer design their exhaust systems to out perform the stock exhaust. then their preset gig-mandrel bend these systems at a mass rate reducing cost. i'll stick to the mazda upgrade because it won't void my warranty. look, exhaust and cai only go but soo far. i intend to gut the cat anyways and tig it back without any signs of tampering. i've done it to all my vehicles except one and have never had a problem. actually gutting isn't the proper description. i tig a straight pipe and wrap the gutted cat around the pipe. its more flowing than a hollow cat.

The best

the number 1

the absolute KING of exhaust systems
is burns stainless. If you've been building cars for 22 years i'd hope you know who they are.

They eat magnaflow exhausts for breakfast.


brand name exhaust systems that are mass produced cannot compete with custom stuff built by the best in the business..

if you are worried about warrenty , why on earth run NOS? NOS is more likely to void your warrenty than a custom exhaust system.

Yes. Exhaust. CAI and an upgraded IC will net those results. Read. Search, look at Dyno's.

 

[tsunami]

i say run the nos... its quick easy and comes at the push of a button... and if done correctly (and in moderation) you shouldn't have problems with that small of a shot...

 

[clos561]

run a 150 shot...post vids too

 

[shane02pro5]

You must have never owned a Mazda to be saying something like that.

thats a hard case to prove, believe me.
