    3000gt MR started a thread Ethanol vs methanol in N54
    Well this weeks N54 trend and word of the day is "band-aid". I dont have much time today but i'm sure this thread will be a mess when i get back to reading it. This is a debate between a properly built meth injection system vs a PI e85 injection system First off when searching methanol vs ethanol you will come across 2 things that are mentioned in just about every comparison. 1. Meth is more poisonous 2. Meth has 67% the energy of 100% gas where as ethanol is 83%. BTW. Both are alcohol based and both are poisonous in high concentrates. Methanol is used in racing, theres even a class for it. Yes the engines are build and tuned different to handle the cooler burn and the added fuel but to everyone's surprise a 100% ethanol engine would be built the same. So is there a distinguishable trait that makes 1 fuel less better than another besides needing more meth than eth? They're anti Knock properties are about the same with the octane being close to equal (R+M)/2 112-115 (although true alcohol readings are not obtainable) So now let put fuel to the side and look at systems. 99.5% of meth injection systems are put together cheap with poor design. On the contrary probably 99.9% of failures is due to poor system design. If your just looking for a minor performance enhancer than sticking 2 smaller nozzles in the charge pipe is fine. When you start getting greedy and keep upsizing nozzles and cranking up the boost is when you run into issues. When you start using it to increase your fuel capacity the charge pipe just became the worst place to inject. Would anyone run their ethanol through their charge pipe to make up for fueling? I know Fuel-it is working on a TB injection system which perfectly fine because they are not advertising 1000HP through it. They have done a great job making it pretty conservative. So lets face it, the only practical place to inject any type of secondary fuel whether its ethanol or methanol would be in the intake runner for each cylinder. As most of you know (based off the amount of txt, PM's, phone calls, tagged posts i get) I run meth, I'm starting to think my nickname should be methhead. I love power, i'm no different than the next person. I have access to 1 gas station that carries E85 and now that my GF doesn't live 20 min from it, its now a 40 min drive. I'm stuck with pump 93 and methanol if i want to make any type of power with a ST. So i went out and designed a bullet proof system that has worked great. I did not invent something new here. I just implemented it on a platform that relies heavily on methanol. For some reason when you start talking meth one of the first things people say is "what if a nozzle gets clogged?" I have no idea where this even came about. Was the first methanol injection systems mixed with sand and unfiltered? Meth out of a VP barrel is already extremely pure, 10 times more pure than anything you get out of a pump at a gas station. If you dont run a filter in any type of fueling system than you deserve to have problems. I run 3 which is 66% overkill. Not once have i even came close to this clogged nozzle BS. A proper meth system has boost kill fail safes which i think most all do now. Todays controllers have a range so if there is leaks or a kinked line it kills boost. Basically if the flow isn't within the user specified range. A proper system needs to utilize the following IPW controller with solenoid function of given fail safes individual cyl nozzles quality lines and hardware remote tank Built like you would build a factory fuel system. Dont be stupid Just about all problems are contributed to these. Some methanol donts: Progressive controllers single point injection CP location for added fuel. window fluid tank dyes no filters Most tuners dont mess with tuning meth injected cars for a bunch of good reasons. You dont know the condition its in, how well its working, blah blah blah. So for a tuner to take the responsibility in tuning something with that big of an unknown is dumb. If something shall happen the first person to always get blamed is the tuner.

    I thought i read somewhere it just had to be turned on at a certain RPM or something rather than let run permanently.

    I thought the 2nd HPFP only comes on after the 1st was maxed out?

    Just got done watching the qualifying.... i'm happy to see someone challenging the mercs, should be a great race! I do wonder if the rain had something to do with it though, but it could easily rain during the race as well..

    you're missing that with 2 HPFP's, unless you're managing to max them both out which, well, props to whoever is doing that!... they'll both be running LESS hard than a single HPFP at any given power level. injectors fair point, except the latest injectors are quite a lot more reliable than they've ever been.

    wait what, that changed? I thought you had to have something extra (like a JB4) to control the activation of the second HPFP? ED: and the single stock HPFP can flow what, 450whp on straight E85? 400? two (not counting injector limits) then could be able to 400-900 then right? and overdriven... well it seems like the fuel pump shouldn't be the limiting factor any more, and if it is well that's completely ok too haha

    Ferrari has shown great improvement on power. They now (in Malaysia) have slightly more top speed and torque than the Mercedes engine. This is going to be a very interresting season. Rosberg tried to block Hamilton or the last timed lap, but it backfired for him. Resulting in a 3rd place for him on the starting grid. Max Vertappen, 17 year old rooky, is the first teenager in 54 years of F1 to start a F1 race from 6th place.

    I have had them fitted on a RHD 1M, no issues at all. I've gained almost 100whp with and additional 3 psi of boost.

    from what i have read dynomation-5 and engine analyzer pro seem to be the most useful, however there isn't a lot of talk on forums on the topic. i've read what i could and in summary the latter appears to be more flexible with more user defined inputs, and b.c of this also needs more detailed information about the engine as less assumptions are made. the big question is do we know enough about the n54 to model it accurately. if we do then i imagine there would be a lot of value in moving the platform forward on the hardware alteration side of it, since the community is relatively small, trial and error will be a long slow process. i wrote performance trends an email asking how i would model vanos, i can see that would be a major PITA having to splice say 10+ simulated runs together to get a representative torque curve. there is a free trial period on it that might be worth playing with.

    Well said Justin. We will soon know exactly how much power two HPFP's can support. There is a good chance we may end up having to either run Steve's TBI set up or a PI set up on top of the DB to get the power were looking for. We should have some results soon!
