Talked to my mechs about nitrous. - Page 2 - Toyota Yaris Forums

ive been running a nitrous setup in my scion tc which has a plastic with a 50 shot dry set up has the same no return line fuel pressure dont have to worry about it the wet system has to up the fuel pressure to prevent a drop in fuel pressure due to the valve opening up when nitrous is turned on mine runs on a rpm based window switch from msd turns on at 3000 rpm so long you are running full throttle and octane above or at 92 your fine. ive ran dry systems through 4 cars already no problems my scion tc, 2 acura rsx, and scion xb. wet systems are more common to engine backfires due to the fact of fuel being added dry systems are not.

You won't ever hear any OFFICIAL advice since Toyota would never sanction nitrous.

All you ever get are opinions, and you know what they say about opinions...

well imo (not that you are asking for it) i don't really appreciate nitrous. Its like chugging down a steroid drink or something. its better to spend money on other performance mods. Too many kids running around with 2 bottles of NOS on the back of their stock hatchback civic swearing they are god.

It is the cheapest, easiest form of power around. Period. It has its place, but using it correctly and knowing what it is doing to your engine is a whole other matter. For all we know, you could throw 50 shots at a stock 1NZ for years without damaging a thing. Nobody knows, but boy do we have a lot of speculation.

turboecho2005 · 10-20-2008, 01:02 PM

The only time nitrous should be used is when you have a massive turbo to spool up

Nitrous does have its place... Its super cheap for the power you get. But remember it can get expensive if you have to keep refilling the bottle. So sure its cheap the 1st bottle and the 2nd bottle... but what about the 10th bottle? or 20th bottle? at that point you might want to consider some form of forced induction or n/a bolt-ons instead.

My 2 cents.

at3GG · 10-24-2008, 03:22 PM

Let me start by saying I've never owned a F.I car or one with nitrous......

I get annoyed when people call nitrous "cheap" or "sneaky" or call those who use it cheaters. Why exactly is that? Is not a professional tune or upgraded turbos on a stock looking car "cheating"? I don't get it. A turbocharged mustang that makes 400whp is awesome but a mustang that makes it on spray is looked down upon oftentimes. On the same note, using racing octane gas at the track is cheating too. If i am at the track and have the opportunity to drive one of two cars....i'll pick the faster one...whether its on spray, whining or spooling. End speech.

ddongbap · 10-24-2008, 04:08 PM

Nos isn't any worse than a Turbo is. Just don't run ridiculus shots and you'll be fine. Same with a turbo. Don't run an insane boost number, and you'll be fine.

richardholdener · 10-24-2008, 07:35 PM

Before testing on the lkow-buck turbo system began, we ran tests on a 40-hp shot using an NOS kit on our Yaris. We ran through a whole bottle atthis power level and never had any backfires or intake damage due to temperature. I have run nitrous with composite intakes on a wide variety fo different applications (inlcuding the 1.8L Scion Xb) and never had an issue with cracking. We even ran the 40-hp jetting on our modified Yaris (120 wheel hp before the nitrous). The result was (peak numbers of) 162 wheel hp and 155 lbs. ft. of torque on the 1.5L Yaris. This was a wet kit injecting nitrous and fuel between MAF and throttle body. Their cracking intake theory is just that-a theroy-real data always works best.

i ran a 40shot with no issues.. it would take a very large amount of nitrous to crack your intake manifold..
