i brought the NOS gas addtive that is supposed to restore horsepower trying to see if any body has every used it?

 

I haven't used the NOS brand, but I've used other octane boosters and noticed slight improved accelaration after the additive runs through the fuel system, but nothing more than that!

 

i used it, i couldnt tell a differente other than maybe i went a day longer than i normally do on gas

 

Use it with Citgo gas highest octane you can get there. It's amazing! I used the NOS brand octane boost with citgo gas and got about 100 miles on a 1/4 tank (i drive my car hard as i can) and i normally got 77 miles to the 1/4 tank.

 

OK find a SUNOCO in your area... they sell race fule... its 100 octain.... its about 3.99 a gallon..but its worth it... get like 1/2 gallons fill you tank with waht you usualy fill it with .. but leave a room for the 100 octain... you can realy feel the power... i get this about once every other month... to clean everything out....


dont get more then 4 gallons!! my friend got about 8 gallons of it and it ran great but when all the fule ran out and we went back over to 92 octain his car felt like ****... o yea .. he drives a Acura TL we race and he wins but not my much (like almost a car)

 

All of that high octane is BS, it only works for maybe a day, untill your ECU adjusts back to normal Octane which is 93, level, unless you reprogram the ECu to run on 100 octane dont bother waisting extra money. Unless u just wanna have lil fun for a day.

 

What about timming..... if its advaced can use higher octain..well... better... after the day ends just reset your ECU LOL !!!

 

huh

 

My thoughts exactly. Good job.

 

lol really???? wow i think that the first time i made a point YAY!!

unless you just making fun of me becuae im such a dumb-***

 

Relax my friend, you are correct. Usually when fuel level (in the tank) changes, your ECU either resets timing to default or simply monitors how the engine responds. My car runs better with 89-or-higher octane, and not just for a day, for the whole tank.
You're not a dumb***, you just need to use spellcheck.

I have no idea what ur asking about the advance timing. (Example you add on a test pipe, first day or two ull see tremdous results, because the actuall flow is much more advance then the stock. Therefor the car is pulling better, once the ECU adjusts to the test pipe thats when the you loose back pressure and return to normal even slower flow) I have no idea what timing has to do with octane, completly two diff performace mods. Take Nascars their ECU is set to 100 octane, and all pro-stock cars are set to 100 however normal ECU is set to 93 the highest. So once again the only performace ull see is for maybe a day. This has been tested alot of times, if you dont beileve, go read how the ECU works, and how octaine works. Not trying to be mean or anything, just making a point.

 

What the hell are you talking about? How does ignition timing affect exhaust flow? The only things that can affect exhaust flow are CAMSHAFT timing and throttle. Ignition timing has NOTHING to do with exhaust flow. "The actual flow is much more advanced than stock," what do you mean? Advanced is a term that has to do with the timing of either the cams or the ignition in relation to the stock timing.

How exactly does an ECU adjust to a test pipe? If you've taken care of the O2 sensor that may be after the Catalytic converter (depending on your car) the ECU won't even know it's there. Normal what? Flow? Flow and Back-Pressure are two different things, if one increases the other is reduced (Bernoulli's Principle)and losing back-pressure is GOOD for performance. Higher Octane = More Advance, go here to learn about ignition timing and octane:
Advanced timing

If the ECU continually resets timing, then how come all other mods aren't only felt for the first day? If the ECU can compensate for a test pipe and reset the timing so that the engine makes less power, then why doesn't that happen with an intake or a Cat-Back exhaust or a Y-Pipe or a turbo/supercharger? You need to carefully re-read what information you pieced together about ECU's, ignition/cam timing, advancing/retarding timing and how ignition timing and octane affect detonation. Besides, Nascar's use Carburetors, the only things really electronic are the ignition and some of the guages. The ignition has it's own controller anyway. You can change ignition timing too, considering that ALL gas is different, just because it says 100 Octane, doesn't mean it's powerful, that's just the level of detonation resistance, which can still change from gallon to gallon.

 

Ok one more time, then im not replying anymore YOUR ECU IS SET TO RUN 93. I never said about advance timing, its completly two diff things, omg, I cant deal with this when im bored at work. I never said about other mods. Please go see how the computer is set to run on 93. NOT MORE, unless you reprogram the damn thing.

 

Maybe you think you can run real NOS on your stock ECU too? If you say yes I honestly wouldnt be suprised.

 

You got nothin'. 'Sides, as long as the ECU retarded ignition timing as needed and the jetting wasn't so large that the ECU couldn't supply the necessary fuel (you can always upgrade injectors, fuel pump and fuel pressure regulator), you should be able to. If you can prove me wrong, go ahead, I welcome proof.

 

No comment I give up.

Well if you ever run NOS through your stock ECU let me know how that works out.

 

My friend Josh who owns a graphics shop has a riced-out '97 Eclipse GS. He has a Blitz body kit, roof scoop and yellow/green paint. Also has a HUGE (I mean HUMONGOUS), aluminum, double-decker wing (with 6-inch single-plane extensions) and 19 (yes, 19) inch wheels (Konig Tantrums I think). Looks a lot like the Phast and Phurriest Eclipse, but slightly different paint. He put on a Nitrous Works fogger (wet flow) jetted for a 100hp shot. He's run it on the stock ECU and internals 4 times already and hasn't had any trouble so far. We're waiting for him to blow it though; he doesn't do great work, plus a 100hp wet flow shot on stock internals is a grenade. I'll be sure and let you know.

 

Jeez.... not a single one of you guys know enough about what you're talking about to make a complete, coherent point.

Yes, you CAN run NOS on the stock ECU. most people do. if you're running more than a 40 shot, you'll also need a fuel pressure riser, and some way to retard the timing while the nos is spraying.. again, not too difficult. several people (NOS and JWT both make them) have daughter boards that supplement the stock ECU and do everything needed to run on NOS.


As for your argurement about timing, the higher octane you run, the farther you can advance your IGNITION timing. has nothing to do with cam timing. mess with that and you're likely to ruin the engine when the valves whack into the pistons.
The ECU will advance/retard timing as necessary for best performance, within it's parameters. it can only retard is so far before it gives up and goes into "default" settings.

as for running 100 octane in your car, you WILL LOSE POWER unless you have an ECU that's set to run it. I filled up with 100 myself once and did a dyno run on it. 132 fwhp. I changed nothing but the fuel (back to 91 octane as I usually ran in my VG), and I put down 136fwhp. no other timing or engine changes between the runs.

FYI, NASCAR doesn't run an ECU. they run carboureted engines.. with BIG carbs.. no fuel injection/ECU stuff there.

 

Was I actually wrong anywhere? All I really care about is being accurate. I would appreciate the input.

 

Oops.. my bad.. you were the only one back there with any factual input. the rest are full of it.

 

That's what i was saying at leats 1000000 times to him, that was my only point, i never argued about timing.

 

Yes you did you kept on saying your car can run on 100 octane...what have you been smokin today.

 

it CAN run on 100 octane. will it run better than regular pump gas? no- at least not without modifying the ECU. he said that.

 

*BUZZER* wrong answer.....why don't you ask "The Max" about that....80 shot on the stock ECU for 3 years....get you facts straight man!

 

Yes that was exactly my point, he can fill (200)"joke" octane if he wants, but hell see no performance gains. Since the ECU is programed on 93. Thats the only thing I was arguing.

 

That's pretty funny, have you had to replace anything major? I'm assuming you have the common bolt-ons, BPU if you will, also.

 

no not my car(though I wish), but its the "THE Max" from Australia....anyways as I recall he's been running 80 shot for the last 3 years only upgrades were Walbro pump and Level 10 auto trans.....point is the ECU is bone stock, untouched.....when I spoke to NOS tech a few years ago, they said with a 65 shot most you have to retard to is 13-14 deg while on the "juice"!

 

Yeah, standard rule-of-thumb: Retard 2 degrees for every ~50hp. I'm guessing THEMax is using 12-13 degrees on juice. 80hp at the touch of a button, god I can't wait for the day.
