Its only Optimax mate.

So considering what you can buy Martini or Sunoco for (much better fuels) i wouldn't waste my money.

I would run with 95RON and some Martini OB (will bump it upto 98.3RON)

and its a lot cheaper doing it that was as well :)

I guess you must be aware its difficult for you to post without it seeming that you are just pushing your vested interest...

Wouldn't waste your money..... I would wager that given optimax is less than 25% of the price then Martini or Sunoco would need to be 4 times as good to make it worthwhile, or hey lets pretend you use optimax and a very expensive octane booster, then I'd like to see verifiable results that you get twice as much "performance" from the Martini stuff.

I bet theres no real way to back even the second statement - the pissweak 98 vs M110 comparo test on the website was done with a completely different tune...... Pricing is conspicuously absent from your postings and from the comparos too.

Its one thing to say x product has awesome performance, but surely most people would weigh it against it being 4 times as expensive!

All I'm saying folks is that there are lots of race fuels around, don't just buy one because its new or lots of people are suddenly praising it.....

How is OPTIMAX 25% less than any of the other race fuels???

Last time i checked there was about 30cents difference in it :D

I have run and used Sunoco for many years and always would over OPTIMAX as its a better fuel, have a better combustion rate and is more efficient for the high boost application that i was running.

OPTIMAX just didn't cut it, never has and never will for me!!!

As for the results on Martini OB then if you had a look the info on the first page and on there site you would see the test they did was with the SAME car/fuel but all they did was add the Martini OB, wound some iginition into the mix until they reached the knock level that they already had from the first run.

In the mean time picking up a couple of extra kw's in the process but without actually adding boost to the application.

Skyline_R32_test.pdf

Lets see you do that with other OB's like *&^%$ or *%$$@ or even $%$@(%$@

What i wrote was based on my own personal experince's from tuning my car and the rebroad minded persons that we found/got.

Funny thing is that 2 out of 3 other people with very similar set up to mine had the same results as well.

Dr Drift has done dyno research with many different forms of OB and came to similar conclusions as well and he use's and recommends the same.

SEE A BIT OF A PATTERN HERE???

Now you can believe what you will but i haven't once plugged or try to push anything on SAU (save it for my own site and when i travel) nor do i push with any other of our sponsors.

What i do do is give my opinion (as thats all it is) and try and help out my friends and people i know if i can in anyway, be it good prices on parts, free labour or advertising.

Truth is from 270 views and 24 replies yours is the only negative one (not sure why) and the only one that expresses a different side of the argument.

Have you used any of the above mentioned fuels or OB's personally???

Can you buy it in at wholesale cost and then offer it others without making money on the product???

Have you done any R&D of your own with your car and a comparison test with over 4 different fuels and 7 different OB's???

My point being that i have and the results spoke for themselves really.

Talk to anyone that has used a certain product and they will give you there opinion, speak to the person next to them that has used the same product and chances are you will get a different opinion.

What i wrote about the Martini OB was based on my opnion as it was for the Sunoco/Martini fuel VS OPTIMAX.

If you want to have ago at someone ele's post stating you would like to see the proof, then turn around with a side of your argument without any proof, then save if for BC.com or ricers R us ;)

It was suggested that the martini fuel was in the region of $147.00/20lt or ~$7.35/litre , whereas optimax was $1.70/litre? More than 30 cents there surely.

lots of stuff about OBs chopped for space

I see a pattern; I didn't mention OB except as an additive to the cheaper fuel. I did get my wires crossed there!

I was comparing the cost/benefit ratio of spending 1.70/l + some octane booster, to spending $7.35/litre, for the average person who lets face it might need more than 95 ron but probably doesn't need full on race fuel.

I also see Martini's website publishing extremely positive testing results from their own testing, reported by a magazine they advertise in! Excuse me for being a sceptic....

The test I referred to was 98 vs M110, not the OB test, and FWIW I think the article makes it fairly clear if you read between the lines that there wasn't a magic 50rwkw in the fuel, more in a decent tune anyway....

As for 95+OB, likely to only see results around the same quality as straight 98 - and I'd have thought a decent OB would cost somewhat more than 30c/litre? I can see its simpler than buying drums though

Out of 270 views and 24 replies it seems your the only person who has used the fuel

Have you used any of the above mentioned fuels or OB's personally???

No, afraid I haven't, really only ever stuck to BP100, Elf, methanol on occasion and when available have run Powermist T112/T10/Dynol 832/TO137 (powermist fuel is a bit exotic though)...

Can you buy it in at wholesale cost and then offer it others without making money on the product???

Have you done any R&D of your own with your car and a comparison test with over 4 different fuels and 7 different OB's???

My point being that i have and the results spoke for themselves really.

No to most of the above I'm afraid. Well, haven't with the car anyway, certainly tried running a fair few different fuels in our racebikes over the years. I'll admit I'm new to what fuels work best in a turbo application, and thusfar I'd just stick to what has been shown to work.

As for OBs I'd always tune for the fuel, not for an additive- too risky IMO - anyway, I was only playing devil's advocate mentioning their use

Absolutely true, no argument here.

I'm sorry if it seemed unduly antagonistic, that wasn't really the idea. Just wanted to spark some debate/verification instead of every 2nd post being "buy martini its great I can get it"; if you follow my drift (so to speak).

I hear what your saying chief and im not having ago at you at all, as thats your opinion.

Like i said at the end of the day its just people's opinions.

Ive never once said buy Martini i can get it, i just recommended it as i have found it to be the best OB on the market at the moment that i have used :)

As for tuning for fuel and not OB i couldn't agree more, but when you factor in the crappy 95RON Premo :P that we are so lucky to have here in Tassie then most people looking for big numbers would normally use an OB to bump it up to see what they can get.

Having said that for the sake of 10rkw's+ it works out to be a pretty expensive excerise when you have to put OB in with every tank.

I personally wouldn't do it on a daily but have done so with my track car and the boat.

As for race bikes, im not 100% sure if your talking about road/dirt but from all the bikes i have ever owned/raced/riden or worked on i have found that using OB or even Premo in some (most only run standard ULP as u would be aware) it not only fowled the plugs and made the bike run worst, i got less k's to a tank.

Id like to know more about your finding's with bikes, especially if it was road bike :)

And im always one for a good argument myself, jsut remember though that it is the net and what someone writes isn't always the way it sounded in there head, nor can you hear the sacarism in there voice :(

Id like to know more about your finding's with bikes, especially if it was road bike :teehee:

Road, dirt, street, race,two stroke, four stroke, singles, fours...Mucked about at some point everything from 1970's 2 stroke vintage MX bikes to GSXR1000 production superbikes; my dad used to own a large Kawasaki/Suzuki dealership and service/tuning centre in Victoria. We (mostly Dad!) raced/prepped bikes for thumpernats, state MX, state roadrace, national roadrace.

My experience is that...

Most roadies do seem to go fine on ULP or PULP, but for race applications and when you're running higher than stock compression sometimes we'd just go straight for the race fuels. Some of the ram air equipped roadies (ZX9R's especially) used to seem to need a dash of isopropyl alcohol to stop carbies icing up, all but fixed with the majority on injection now. And I think now most circuit racing requires non leaded pump fuels anyway doesn't it?

Not to mention that since most bikes are jetted/run plugs suited to ULP/PULP, it takes tuning and mucking around with maps, jet kits, doing plug chops etc etc to get any small benefit on the road out of other fuel; not really worth it generally.

BP100 is more than adequate for most race bikes, two strokes seem to run fine on ULP or sometimes PULP, however on older air cooled race bikes (especially two strokes) we found the race fuels were useful in reducing combustion temps hence temperature related seizing/pinging.

We ran Powermist race fuels because we were able to backdoor it from Team Kawasaki Australia (who were running it in their 750cc superbikes and as I recall were backdooring theirs from Muzzy's in the USA, haha), and the bike it was being used in primarily tended to run quite hot ('97 KLX650R grasstrack MX bike with serious engine mods, i.e. 13.5:1 comp, carillo rod, wiseco forged piston, white bros custom cams, modded head and 65hp at the tyre, did over 200kmh at Finke, radared at 153kmh at Geelong thumpernats - in 4th!) the cooler burning fuel helped somewhat.

Oh, and everything seems to hang together longer running motul oils; can't recall ever having a blowup on motul 2 stroke, and seemed to get better service life out of most 4 strokes with motul oils.

Our 1981 2x4 Hilux shop hack with a tired 18R seemed to go noticeably better on BP100, in fact even when it had 2 stroke oil mixed in it, and on occasion seemed to like the Powermist Dynol832 - you find these things out when you run low on fuel and have a few drums of race fuel in the back, haha.

    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
