Ok for those that know him, hazkells Supra (7MGTE) went from 148rwkw (95RON) to 182rwkw (98RON), there was a slight boost increase...

this was on the same dyno with the same tuner and both tunes done about the same time of the year

I have changed to 98 ron, Prior to running 98, I sometimes used shell pulp and sometimes the knock would go to 30. Since runnind 98 ron, my knock hasn't gone over 13. I wouldn't say its has anymore power, but with less knock its well worth it. I haven't had it tuned for 98 yet but will do in the near future.

Guys,

Heres my 2 bobs worth.

I have been using BP Ultimate (98 RON) for the last year in my 32 GTR. Before it became available at the pump I was purchasing from Selfs Point in 200 litre drums. Car is tuned at Pro Automotive and I certainly noticed the power increase.

I raced my car at Baskerville couple weeks ago using BP Ultimate purchased out of the bowser from BP Brooker Hwy. The car actually felt down on power to me and felt reluctant to hit the rev limiter.

So I also share a concern on the quality of the current fuel.

Rod.

Well........ As the person selling it, all i have heard are good reviews. Ultimate is 98 at minimum, closer to 99. The stuff has four times the detergents than regular fuel which means it cleans your engine and prevents build up, also anti-corrosion. Just for that i'd put it in my car. I think one of the main causes that produced the knock in my car that lead to the detonation on the way back from Devonport was because of the fresh tank of PULP after running it on 98RON in Melbourne

Still doesn't explain the mixed results everyone has been getting with the 98. I can understand those that haven't had tunes not seeing any difference but for the many that have paid for dyno time and have ultimately taken a step backwards, it doest really say much for that!!!

Like i mentioned before i run the truck (454 big block) on 98 and it does run better (pulls better down low and easier while towing) but i have also used it in a few other vehicle (cars & bikes) and i haven't seen any difference and not going to rush out to tune with it at the moment either!!!

Well at $4-8 dollars a tank I think it is worth the risk. standard ECU's run super rich and safe so you are not going the get a leg-up from slower burning fuel.

The guys runing 3rd aprty ECU's and dedicated tunes are going to see a difference for sure... and it wont always be good.

One problem we have in Tassie is volume, it will sit in the ground and in a tank that has been used for a couple of different fuels in the past. The boat I believe brings all fuels so there can be cross contamination there... add all the little things up and it is not ideal.

We have used elf for the last 3 years... not always for performance gains - but just the fact it is consistent.

I can't get over the people on these forums who spend hundreds of hours and countless dollars on performance mods, then skimp on fuel.

While the power output via a standard ECU may be marginal or even down - I am reasonably comfortable saying that it would not be harming your car.

As for knock - all the Apexi users should know within ten minutes of filling up if the fuel is sus...

Now Rosie - I am to undertand you have lunched another engine? Phew, thats gotta hurt - I hope not.

Just out of interest, the people experiencing losses, do they have piggy-backs or stand alones?

I find with my SAFC II that it goes out of tune after a while anyway due to the stock ecu constantly learning and altering it's settings.

Before I go and get a retune for 98RON I'll be resetting the ecu, using 98RON for at least a few weeks, and then getting the tune redone.

With a stand alone I gather you should be able to dial in some more timing straight off the bat as you are the one inputting the settings into the ecu as apposed to the ecu learning and altering for itself

1. elf LMS (now WRC)

2. Devonport Tyres I think

3. when I last bought $980 for 200

4. The only 102RON fuel I have used... horse power in a drum!

Will be looking at all options for the Valiant, but it will need to be very attractive to change.. one reason to c hange is we will probabley get away with 98 given our stock tune.

But if you want "Numbers McLaren" to dial up the goods, use the good stuff

For everyones benfit as I emailed this to BOV and Kerry.

Sunaco GT plus - 102RON - $740 a drum - Scott Foster.

Awesome stuff and comparable with Elf WRC... Elf won't agree with that statment ofcourse, but its seeing the same numbers on the dyno.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel

      What should I do next to hold the head on

      By MBS206 · Posted

      When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?

      Chris' Toyota Mark ii JZX110

      By Rezz · Posted

      Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.

      If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
