The only research on octane boosters that i have seen shows that they do stuff all. If you really want to change the octane rating of pump fuel you will have to add 10% or more of something like toluene or ethanol.

Hmmm... it looks like you missed these articles then:

20% Toluene +2.5RON

500ml Nulon Octane booster (60l tank) +2.8RON

Octane booster in action

Quote: "Both the Nulon Pro Strength and the NF Racing Formula rated the best octane boosters in our test... ...Still, both proved extremely effective at increasing octane, even outranking Toluene, which needs much higher levels of concentration."

Why bother running around trying to source and use large amounts of toluene when you can buy a bottle of superior Nulon octane booster anywhere for $25?

The guys doing these tests know WTF they are talking about... more than can be said for some on these forums! :down:

All respect SK but don't the Japanese factory ECU's in the RBs have fuel maps for the 100RON fuel used over there?

In an "untuned" RB (factory ECU) I thought that running a decent octane booster with 98RON local fuel would have benefits

i.e. running the octane that the ECU is mapped for... even more so to avoid detonation with increased boost levels + hot weather?

Clearly it's a different story if your aftermarket or factory ECU is remapped for 98RON

I was about to go out and buy some but not so sure now icon2.gif

lol you do realise he said that on 21 Jan 2005, 07:18 AM ? :down:

Yes you're right. I did my research years ago and all the products produced only a fraction of a RON number so I have never bothered. I don't remember seeing Nulon mentioned at the time.

Well I do neither. I am using a petrol from Gull called Force 10 and it is a 98 petrol with 10% ethanol added. It enables me to run more advance and more boost. I have always used it on my car so I cant provide before and after figures. If I were in Aus I would use E85. There is a comprehensive thread on that in the Skyline section by Guilt Toy.

I guess if you lived in an area where you could get only low octane petrol Nulon would be a solution.

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
