Suprab1 Posted January 28, 2010 Share Posted January 28, 2010 guys on the site say hub hp is the same as fly. however there has to be some transmission loss how much not sure. tween 400/450.e85 is 90 cent a liter compared to 130 unleaded cent in dublin so id say thats quite a difference.72 euro for a fill up uk spec tank with e85.104 euro for unleaded. Yeah thats a nice bit alright. I can't get E85 here but think what Marty said makes me just want to stick with E5. If you get mapped on E85 then in the winter when its only E70 that can't be great for the car. Quote Link to comment Share on other sites More sharing options...
bondango Posted January 28, 2010 Share Posted January 28, 2010 Hi Marty I'm playing with the single idea. I know its expensive but i would do it in stage's. are the single supras that you know running safe on E5? thats my biggest fear going single and not able to get good enough petrol for it. Yeah, E5 is a bit of a savior for most in the South. It is a Genuine 99 RON fuel, but you can run a single on poxy unleaded 95 RON- that's were your mapper earns his money so to speak, it would be a very safe and power conservative map. But, with most ECU's now days, you have dual maps (solaris EMS for example), so one map for when you cant get E5 (safe map), and then your E5 map (high boost performance map) Quote Link to comment Share on other sites More sharing options...

Nigel, there is no actual money saving really. You use around 1/3 more fuel when running E85. As said E85 isn't a replacement higher Octane unleaded fuel, its an ethanol mix Quote Link to comment Share on other sites More sharing options...

So what you just press a button when you fill up with 95 and it goes into safe mode is that how it works? Quote Link to comment Share on other sites More sharing options...
bondango Posted January 28, 2010 Share Posted January 28, 2010 Ah right cool.

nigelboyne Posted January 28, 2010 Author Share Posted January 28, 2010 all i am interested in is getting the best fuel as not to blow the engine highest octane. will keep adding 10 liters of e85 to a full tank.i add smaller quanties eveyday to my accord. if nothing else it keeps temps down and emmisions very low. does trigger engine management light if you add to much which can be bad for vavles and pistons Quote Link to comment Share on other sites More sharing options...

If you're adding enough E85 to make the engine management light come on you could be doing damage to more than just your valves and pistons.

JamieP Posted February 1, 2010 Share Posted February 1, 2010 How about running a few litres of Xylene in every tank? its 117 octane and basically what octane boosters are made up off. Google it and read up for yourself before you use it, dont come moaning to me when your engine has blown up:D Quote Link to comment Share on other sites More sharing options...
Thorin Posted February 2, 2010 Share Posted February 2, 2010 I know people have used Xylene too, similar to Toluene, but while neither are particularly nice, I think Xylene is particularly nasty stuff and much harder to get hold of? Quote Link to comment Share on other sites More sharing options...
JamieP Posted February 2, 2010 Share Posted February 2, 2010 Xylene is easy to get, i bought 100 litres from ebay last night. Quote Link to comment Share on other sites More sharing options...

Jellybean Posted April 9, 2010 Share Posted April 9, 2010 (edited) I ran E5 for a while , reset the ECU , ran Texaco Techron , reset ECU and found the Texaco Techron to give the best performance. I did not see any positive difference in the E5, found it a little sluggish compared to Texaco This is all on 0.9/1 Bar Will try it again at BPU, 1.2 bar ECU SARD Analyse http://www.mkivsupra.net/vbb/showthread.php?t=192708&highlight=sard+analyse Edited April 9, 2010 by Jellybean (see edit history) Quote Link to comment Share on other sites More sharing options...
CanisLupus Posted June 6, 2010 Share Posted June 6, 2010 Just wanted to dig this up cause it crossed my mind today as i was at the gas station ^^ The 98Octane was 1,409 Euros and the E85 0,959Euros. Now to come to the point: Lots of my Friends at a Volvo Forum drive their T5s mixing unleaded with E85. Percentage differs but all were on Stock ECUs,Stock Fuel lines and so on. So no E85 Tuning for more Power just for reducing the cost My question now is what percentage of E85 can a Supra TT Jspec take? Any considerations about the fuel lines, boost level or smth else? What would i need to change to drive with let's say 20-30% of E85 per full tank? It's not for the Power gain, it's just so much cheaper Quote Link to comment Share on other sites More sharing options...
