Psh Home made race gas(via your local chemical wholesaler or work hookup) One gallon of Propylene oxide(Oxygenator in the nitromethane kind of way)which EXPENSIVE, one gallon of Tolulene (sherwin williams for $14 bucks, omit if not advancing timing or increasing boost/compression) to ten gallons of premium gas. The propylene oxide may be federally controlled now (F**King anti-terrorist laws) but it's good for about a 6% boost in power, and the tolulene is a knock inhibitor that bumps the octane rating of the fuel to around 110-115 letting you crank the boost. You will go through A LOT of fuel but it's power in a can.

Very few of the octane boosters at the advance auto work the one that worked the best was the NOS octane booster in the box used 2-3 per tank and it would let you run a 100 octane map. The ones that say they will raise your octane 6 points mean .6 octane hence 6 "points." The gallon of tolulene beats all in that department ~7 full numbers for $14 and ~14 for $28. Careful though the PO and Tolulene will take their toll on plastics if you use them continously so i'd save it for track days and flush it out with 93 at the end.

this topic is getting hot~!

Wow! Rep for that knowledge. Very informative :tup:

I'll PM Ryan at Injected Performance (one of the forum's sponsors) and ask him to chime in on this, seeing how he's the one who did the test and made the video. I'll let him know that you're calling him out as a liar and a fraud.

OK, sorry! :)

:tiphat:

I'am afraid you are confused.Race gas and oxgeanated gas are two different things.I stated that a stock 370z will not in any way make 14 hp more with race gas.I said nothing about oxgeanated fuel.Apparently you don't know the difference.I believe the original post was questioning different octane ratings
of race gas.Not oxgeanated fuel.
As for me speaking my mind on this forum I thought that was it is all about on here.Sponsor or administrator it shouldn't make any difference.We are all equals on here as far as our opinions!

Also my friend you used the words "liar and a fraud" not me.So they were your words.Have a nice day!

dun worry it's does surprise ppl girls need a car like this lol

The XXX racing fuel is oxygenated. In fact, it is one of the most oxygenated fuels available on the market. Typical race gas on an otherwise stock car is, like the rest of this thread states over and over again, not going to do much at all. I know I wasn't being called out, but I just wanted to make sure everyone is on the same page :)

Here is the original blog post and video, just for reference: XXX Racing Fuel Gains 14whp on Stock 370Z : Injected Performance Blog

The video basically speaks for itself. Baseline dyno pull, adding five gallons of the XXX gas, then running it again. We don't carry the fuel, we don't sell it, and we have absolutely no bias towards or against them. The company was touring near the area and decided to stop by to advertise their product. Being curious like everyone else would likely be, we took them up on their offer and did a dyno test then and there.

The power gains are almost entirely from the oxygen content rather than the octane level. The XXX fuel used has almost twice the oxygen as other products on the market, like VP's Q16. Was it an interesting experiment? Of course! Is it a fuel that we would recommend for everyday use? Not really. It is being marketed as an alternative to race gas, and I wish them luck in getting the product out there.

hahahah GO RYAN GO!

Thanks for the info, Ryan.

Blown32, don't get your panties in a wad. Listen, I think this is important. A forum member -- a sponsor no less -- has produced a video showing that XXX oxygenated race fuel produces a 14whp gain in a stock Z. Now, if it turns out that the dyno results were somehow falsified, I think that needs to be exposed. Indeed, if it turns out that the claim of a 14whp gain is BS, as you put it, we'll all owe you a debt of gratitude. On the other hand, if it turns out that the results are valid, then it's important to know that too. We're all after the same thing here -- we all want the truth. For the good of the community, we all want to vet out misinformation, do we not? So ease up, this isn't about you, and I wasn't trying to suggest that you shouldn't express opinions if they contradict those of a sponsor. Rather, I emphasize that IP is a sponsor because if a sponsor is putting out misleading or false info, it's all the more important for it to be vetted out.

As for the original post being about octane ratings, that's certainly true. But I am not the one who opened the door on this race fuel tangent. The OP is actually the first person who alluded to race fuel when he posted a link to gas stations that sell race gas in SoCal (post #5), and then Bullitt mentions it in post #22.

Again, I'm just trying to get to the bottom of this for the sake of getting at the truth. I presume that's what you're interested in as well, so we're really on the same side.

No problem and your info is real interesting.Just that some people relate oxygenated fuel as ordinary race fuel and it is in a class all by it self.So was trying to get that message across to some on here that were confusing the two.
Very impressive results and thanks again for sharing the test results.

Back on the topic of octane ratings, have you guys noticed the slight difference between US-spec Zs and Australian-spec? According to Rudi (post #18), "In the manual for the Australian version, it states: Use UNLEADED PREMIUM gasoline with an octane rating of 98 (RON)." That works out to 93.1 AKI octane, according to this: US Octane VS Other countries Octane Ratings

In the US manual, it says to use 91 octane, and even says 96 RON in brackets. It's only a 2 point difference, but I wonder if we should infer anything from it. Like maybe the engine is in fact optimized for 93 octane? *shrug*

Hmm so this XXX fuel thing is interesting. So the basic idea here, if I'm understanding correctly, is that it's a higher octane fuel which also has added oxygen - and this means the extra oxygen in the fuel is effectively leaning out the mix for more power, and the extra octane is preventing the knock that would otherwise occur if you leaned out the mix that much on pump gas?

That's how I'm interpreting it (not that I'm an expert on fuel by any stretch of the imagination lol). I mean, that's why I find this so intriguing. The idea that you can just pour some of this stuff into your tank and get an immediate 14whp gain -- how can that not catch one's attention? And if I'm understanding the video correctly, they poured it into a tank that already had some regular fuel it, so it was like a 50/50 mix. I'd like to see what would happen if you poured this stuff into an empty tank! :excited:
