    I know it may seem like it after rereading what I wrote I wasn't saying that one is more superior to the other. Just clarifying a few things

    It's obsoleted? Has someone released a superior direct injection fuelling solution for the N54? It seems you're implying PI has... any advantage at all over DI, at equivalent flow levels..

    Someone sounds a little upset that the benefits of their Shotgun are now Shotgone. Can't say that we blame them, it is unfortunate to put much effort into development into something only to find out it is obsoleted before even shipping them. The idea was clever and the innovation was there, but just a little too late. For those who still believe in it, pick one up, my bet is that you'll still be converting to PI within a year. Rob

    Flinchy replied to a thread Ethanol vs methanol in N54
    E85 has 69% the energy density of gas per volume Methanol (100%) has 48% http://en.wikipedia.org/wiki/Energy_density http://www.ibchem.com/IB/ibfiles/energy/ene_doc/specificheatcaps.pdf meth has a slightly higher specific heat capacity, which might be one reason? methanol is cheaper than ethanol i can't particularly find anything else for methanol having any advantage over ethanol. Though with more being injected per horsepower, AND having a higher specific heat capacity, it would provide superior cooling no?

    so no need for anything more fancy than boost level x = pump2 on? that's pretty cool. Completely seamless correct? DME just sees the fuel and dials itself up/down accordingly i take it?

    Also to answer some of the questions, we tried a bunch of different activation methods while testing, we did have controllers made, but it is voltage PWM regulation box with a knob on it, clockwise more PWM or more fuel, counter clockwise less PWM or less fuel. But once we got everything really dialed in, we started letting the DME control the second pump as well completely, we have a hobbs switch that can come basically wherever you want, we have it set at 15 psi, so 15 psi the second pump comes on, and the DME now has control of both pumps.

    Flinchy replied to a thread Anyone fit VTT inlets RHD? in N54
    where'd you find out the TFT inlets don't fit? I heard they were installed without modification by a guy in perth? and the VTT ones are supposed to go to the stock pipe locations, so fit up to a stock box style intake? could be wrong, but that's half the point i thought.

    Ok,. lets hear it. I am ALLLL ears, go find all the threads where we are talking about Vendor X, then find the ones he cannot stop talking about us, I will wait. Also lets talk finished products lets just make a quick list. Us: N54 Stage 1, N54 stage 2, N54 Stage 2+, N55 Stage 1, N55 Stage 2 DBB, N55 JB, S63TU Stage 1, N63 Stage 1, Shotgun HPFP upgrades, Silicone intake tubes, shall I keep going, cause we have more? Vendor X, actual finished released products, 15T hybrid turbos in FIVE YEARS. The end. You are 100% correct, the LULZ never end!

    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.

    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.
