Gamer Posted December 26, 2006 Share Posted December 26, 2006 IIRC Envy do some race fuels and also run some in their Supra. Might want to give Gaz a shout and see what he says if no one else chimes in. Quote Link to comment Share on other sites More sharing options...
Jake Posted December 26, 2006 Share Posted December 26, 2006 I can't see why you would run a road car on race fuel, unless you had it mapped at two levels and could easily switch between the two maps. Who wants to sit in traffic wasting £3 a ltr race fuel while ticking over? Who would buy a road car that needed remapping before it could run on pump fuel? If you're only going to be running 1.0 bar then you'll only see performance gains by running a bit more more timing advance - and the gains won't be all that much. It's never worth it.

Jurgen-Jm-Imports Posted December 27, 2006 Author Share Posted December 27, 2006 jake its my weekend car i will only use race fuel to get more performance out of it, and keep spare race fuel in my unit.. this is what am intending to do send race fuel to wgt and get it mapped there and fill it up there to brim withg race fuel and when am at home and fancy a blast pour some race fuel in and enjoy.. and always use race fuel:) Quote Link to comment Share on other sites More sharing options...
Jake Posted December 27, 2006 Share Posted December 27, 2006 But only run it at 1.0 bar? (It's not really clear if that's what you intend to keep to or whether you're just claiming 500bhp at 1.0bar) Quote Link to comment Share on other sites More sharing options...
Jurgen-Jm-Imports Posted December 27, 2006 Author Share Posted December 27, 2006 sorry mate i will use around 1.5 bar on race fuel and maybe have around 600-680 .. but it will only be used with race fuel the 500bhp at 1 bar is genuine proved figure on optimax Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 27, 2006 Share Posted December 27, 2006 Ask Anders at that company, but I would go for Sunoco Supreme, and have the extra margin of 114 octane, leaded. What ecu is on it? You might get through a couple of widebands if you do a lot of miles, and the ecu HAS to run closed loop, but compared to fuel costs it's neither here nor there. There may be legality implications with race fuel in road cars with emissions and tax. Quote Link to comment Share on other sites More sharing options...
Wez Posted December 27, 2006 Share Posted December 27, 2006 Wouldnt the 260GT unleaded stuff be ok as this would save widebands. Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted December 27, 2006 Share Posted December 27, 2006 chris its running apexi power fc, i was hoping there was some sort of street legal race fuel:) I would ask someone more into turbo wankels than I am, maybe do a search on someone called Matt "The Hitman" who specializes in mapping rotaries in Oz, mainly on Haltec ecu's. I know N/A rotary race engines don't need much octane at all, but you need to see what an expert thinks a turbo rotary is best on. My only doubt is tip seals and lead or no lead. You need to ask Anders about the tax situation with his imported fuel, does it have road car duty paid on it, and are there any other gotchs, if this bothers you. Pip Gardener at WGT is a good friend, if you get stuck I'll ask him what he uses, I know he's also an agent for Anders fuel. Quote Link to comment Share on other sites More sharing options...

Thorin Posted December 27, 2006 Share Posted December 27, 2006 The "Cool Blue" 104 race fuel from 76 racing was street legal, I notice now that it's discontinued and they say call for alternatives though. Quote Link to comment Share on other sites More sharing options...
Gaz Walker Posted December 27, 2006 Share Posted December 27, 2006 Hi Jurgen, Ask Pip what he recommends. Our next race fuel order will be in Feb so can get almost anything ordered in before the season starts, just let me know Gaz. Quote Link to comment Share on other sites More sharing options...
