    • 8-seconds on 93 octane - AMS Omega 12 Nissan GT-R running 8.64@160.14 in the 1/4 mile

      Not only is this 8-second performance on 93 octane pump gas it is 8-second performance on a full weight daily driven GT-R. Just absurd when it take all kinds of exotic fuels and supplemental fuel system work to even approach this level on other platforms.


      To be perfectly fair water injection plays a large role here but that does not change the fact this is daily and repeatable performance on the street.


      This GT-R is tuned on the Ecutek RaceROM 7 platform which controls the water injection as well as the upgraded injectors:

      • Improved memory management allows for 16 Custom Maps on all ROMs and future RaceROM updates to have additional features
      • Secondary injector specific lag times for 12 injector setups, smooth transitions on ID2000 secondaries
      • Injector low PW compensation updates for easier understanding. Map tracing added for tuning
      • Boost control updates for integral duty activation to help prevent windup
      • Usability improvements to Clutch Slip Protection
      • Torque Control sub-system to arbitrate requests from TC and CSP with live data for each channel
      • AFR measurement uses internal OEM vales, original RaceROM versions available but depreciated
      • Flex Fuel specific over-boost fuel cut limits
      • Launch Control specific boost targets and torque limits
      • Live Data enhanced with more data and optimised speed (70 Parameters at 20hz)
      • Various map improvements and bug fixes

      Yes, there is more in it on race gas or E85.

        Change the title 93+ methanol this not even close to 93... They have fuel volume, they needed octane. Nice try.

        Congrats, if we put 6-7 figures into a GTR I'm sure we can do the same...

        Yeah methanol is amazing. It raises the octane of pump fuel significantly.

        IMO There are lots of LS-swapped vehicles that go 8's, 9's on methanol injection, using a $300 engine sometimes.

        We live in a day and age where I think its far more impressive to go high mileage, and faster, using the low cost budget solutions. Anyone can throw $$$ at a car and make it 'fast'. Its not even that fast. Isn't the world record for stock bottom end 5L engine from 2004 (cheap engine) around 7 seconds?

        7 figures? you know that goes up to $9,999,999 right? Click here to enlarge

        Who's putting even the lowest 7 figure amount of $1M into a GTR build?

        Things add up very quickly actually, 7 figures is pushing it but it can get there.
        Especially when you have 2-3 spare billet engines (each can cost 50k at least), transmissions, axles, rear ends, etc when you go to race events.

        An apparently acceptable cost for maintenance of 1k rwhp is approx 10k/year

        Axles, bearings, driveshafts, rear ends, trannys, water pumps, dampers, fuel pumps, meth pumps, valve springs, pistons, rings, bearings, oil pumps, etc etc etc etc. Just put 6-8 weeks a year when the car will be down, maybe a winter and summer downtime, or spring and fall, and $10k or so a year in maintenance and parts. That is what it takes to maintain a nice 1000+ setup.

        #include a part time job to pay for maintenance at 1000rwhp;


        The breakpoint for $100/year by comparison seems to fall around 500rwhp, many engines produced 02+ will tolerate 500 to the tires with just oil changes, across many platforms. Especially with race fuels like E85 available now easily. 500 is considered stock engine territory, "low power" or lowest, the lowest any car could possibly be expected to contain at random with any engine. Any less and it doesn't even register on "cars" list anymore. In that imaginary list in the back of ur head 500 is still mostly stock.

        The break in cost for those setups is widely varied. While 1000rwhp is possible using stock LS engines and fragile cast pistons, is it really viable to foster those relationships? Should we be pushing stock engines to 1000rwhp on a dynometer and at race tracks just to see how long they last?

        It was not methanol but water injection. No methanol.

        Really, we here have no idea what it used. It probably used E85 or Aviation fuel because they probably aren't stupid enough to actually put gasoline into their expensive engines. Honestly if I wasn't there and I didn't see it, I can't actually believe what is written here.

        And I am not sure why it even matters, what was the point anyways? LOL even if you did invent an engine that would tolerate 93 and 40psi of boost I would still expect any sane person to use E85 or similar anyways. Why would you give up the benefits of alcohol in the first place? Gasoline is intended for applications where thermal efficiency is important, i.e. saving fuel, generating and conserving heat. Anybody on gas is trying to save a dollar. In racing, the only time you need to do that is when fuel mileage is important, or there is some restriction with fuel usage, maybe it is mass limited or something. In that case you need gasoline, sure.

        Um no and it is 93.

        It has water injection per cylinder using more accurate advanced injection nozzles.

        Water injection is such a remarkable technology, old tech that has been newly optimized and refined

        Facts are correct last I checked... no methanol so you're the one that's wrong.

        It's still there under the time slip picture...

        This GT-R is tuned on the Ecutek RaceROM 7 platform which controls the methanol injection as well as the upgraded injectors:



        • Improved memory management allows for 16 Custom Maps on all ROMs and future RaceROM updates to have additional features
        • Secondary injector specific lag times for 12 injector setups, smooth transitions on ID2000 secondaries
