Noz Posted May 21, 2019 Share Posted May 21, 2019 Would there be a benefit to have a separate tank running e85 on a 7th injector into the intake. To trade fuel for e85 during lower end pulls. A little bit like nitrous. But nitrous below 3k isn't safe. So a more aggressive response lower down. Only a random idea. Quote Link to comment Share on other sites More sharing options...
Style Posted May 21, 2019 Share Posted May 21, 2019 Like a water/meth kit kind of thing? Not sure how you'd be able to go about it as the ECU would need to know the ethanol content so it can adjust the map. If the ethanol's coming off an independent system, it might be difficult to accurately measure the dosage you're adding. The fuel's need to be mixed prior to injection so a flex fuel sensor can pick that up. Might be easier to just integrate ethanol compatible components into the primary system. Interesting idea though, I bet someone somewhere has it working! Quote Link to comment Share on other sites More sharing options...
Noz Posted May 21, 2019 Author Share Posted May 21, 2019 More like a pre spool kick. Like a nos shot for spool. But lower rpm. I'm not totally sure it has the right mechanism in the ignition system to be used in such a way. I may be totally mis understanding it's capabilities. But only an idea! Was thinking of the lowest usage but adding value to a system. Quote Link to comment Share on other sites More sharing options...
Style Posted May 21, 2019 Share Posted May 21, 2019 I think NOS and Ethanol serve different purposes so I'm not sure how they'd compare. My understanding is that NOS is basically power in a bottle whereas ethanol allows the ECU to push the boat out a little further with timing. So it's finding a way for the ECU to keep an eye on this that might be difficult to sort out. It would be bad news if the injector got stuck shut and the ECU doesn't know about it. If you could sort that aspect out then maybe a constant volume entering the system inside an RPM window could be quantified and adjusted to suit!

Noz Posted May 21, 2019 Author Share Posted May 21, 2019 Yeah I was thinking would e85 ever be used for lower down grunt. Not for all out power as such. But lower end torque before spool takes over. Much like the process of nitrous for spool. Quote Link to comment Share on other sites More sharing options...
Noz Posted May 21, 2019 Author Share Posted May 21, 2019 Interesting here it seems only beneficial at high rpm. Really I hoped for a lower rpm response. Quote Link to comment Share on other sites More sharing options...
