5-0 Ignite

How they compare are covered in the link above 'Tech' on coils'. The R8 coils have an enclosed rubber stem where the spark plug's insulator stem seal on to. In comparison against 35R/RB's etc. the coil slips loosely onto the spark plug. Again, it has been mickey mouse for many who have done the conversion world wide.

We are now offering a limited time free domestic shipping, Australia wide, in conjunction with our recent release of the motorsport harnesses. If you are looking for a strong and decent spark delivery for high boost setup without breaking the bank, this is definitely for you!

The valley cover cannot be used with the conversion kit. Good set of OEM or splitfires are fine if you have a mild build but the limits will be found when you start pushing higher boost/power and realise you have to tighten the plug gap down severely to 0.5mm or 0.4mm in some cases. Big HP lads upgrade to Audi R8/LS/R35 coils for that reason so they don't suffer from combustion efficiency problem or spark blow out running at optimal gap.

If you are running -8AN all the way (~9.5mm inside diameter), with flow of 530 LPH, the approximate pressure drop would be 4.5 psi. This will be reduced if you are running teflon hoses or reduced the total length.

Ahh yes. Anybody building a serious track weapon would upgrade more than just the fuel lines. Majority of the owners have their car street driven and upgrading fuel lines to a bigger one whilst keeping road worthy could be a challenge and expensive. How much boost you run is important on selecting the right fuel pump for your application (making sure it can flow at xx psi) but not to sizing the fuel line. To keep it simple; - From the above, we determined that the maximum flow is 238 LPH with approximately 8.5 psi pressure drop (it can flow more but with significant pressure drop). - 238 litres per hour is 3967cc/min. To have a rough estimate on how much power it can handle on the 6 cylinder application, we apply the rule of thumb just like how we size injectors. 3967/6 = 661cc/min. For typical 6 cyl, 660cc injectors can normally output 660hp at the wheels on 98 RON.

We were in this position when we researched on how much the stock fuel lines can flow. With limited information, we decided to do the testing ourselves and share it with the community. As always, if you spot a mistake, please advise us and we will be happy to amend. Author: 5-0 IGNITE Original article from our website; https://www.50ignite.com/blog/technical-blog/article-2-pressure-is-sky-high/ A POINTLESS EXERCISE #justsenditmate Figure 1 - The boat on the dyno Those who pondered on why we stopped at 603whp/27 psi on the project R33 GTR read on…. It wasn’t by choice, we were limited. When we built this car, we had one vision to go by; STREET DRIVEN. For anyone who desires a go-fast-boosted street car - you will always come across the tough decision of which turbo should you go for and how important the turbo's response is. You are not at the track, you need those down-low torque or at the very least, a strong mid-range for performing street duties and occassional track days. There is no fun in it over-selecting the biggest and (inherently) laggier size turbo you could afford only to be chopped by a Honda until you hit that 6000rpm. We don’t condone street racing but the truth is, any car enthusiast regardless of age or gender will give it a squirt once in a while. We selected a compromise of power and response on the RB26. We love our Garrett, Turbosmart, 6Boost, Tomei and Haltech products. Looking at very few compressor maps on Garrett GTX Gen 1 turbos (this was 2016 mind you) and drawing lines based on flow and pressure ratio to find the right efficiency on ‘What if’ power level, we settled on the GTX35R with 1.06 twin scroll rear housing. This turbo was chosen after much discussion and thought, we concurred that it won’t be too laggy of a turbo setup and should yield about 650hp at the wheels on the small but mighty 2.6L. From there onwards, a forged internals build started and supporting mods were chosen; 6Boost twin scroll manifold, Plazmaman intercooler, Tomei cams, Turbosmart fuel regulator, Turbosmart external gate, Turbosmart BOV, Bosch motorsport injectors, 3 Walbro 460lph fuel pumps (1 lift and 2 feed, in parallel configuration) for E85 and so on and so forth. We had a stop to think, with this much fuel feeding the beast, how much can the stock fuel lines be able to cope? Can it flow enough to match the fuel delivery? The answer to that question at that time was simply #YOLO (we don’t have Instagram by the way) and #justsenditmate. Information on the internet as to “how much does 5/16” (8mm) fuel line can flow at xx pressure” was sketchy at best and inputs from the forums were a pure guess based on “my dad’s friend’s uncle’s setup” etc. Nothing was solid or backed with numbers, so we thought that it would be a good opportunity to see how much indeed stock fuel lines could flow and answer the question for the world. During the last tuning session at WTF Auto, Tristan dialled in 30 psi on the Haltech. The dyno session stopped not long after, as fuel pressure dropped the moment we hit full boost. We re-checked the fuel pressure at the FPR and checked the fuel pressure at the fuel pump outlet. The pressure at the FPR was 55psi base, exactly to how it was set, but the pressure at the pump outlet was 90psi. That is a shocking 35psi pressure drop across the hard lines! The over-pressure relieve valve on the Walbro 450 LPH is set at 120psi from factory, so if we are sitting at 90 psi base pressure on the fuel pump outlet and we add 30psi of boost to the system, quick math shows 90+30=120 psi - all adds up to trip the relieve valve. This is why fuel pressure dropped the moment we hit full boost at 30psi. Figure 2 - Power limit before stock fuel lines can't handle If you have read this article this far, congratulations! Because we are about to bore you even more! To understand what was going on, we needed to do some quick measurements and look at fluid dynamics. It is somewhat valid to some degree to assumed that most Japanese cars that run 5/16” (8mm) outside diameter fuel line (bar the soft lines). Fluid flow and head (pressure) losses can be contributed by major and minor losses in the system; Major loss - Head losses due to friction within the pipe affected by flow velocity, pipe length, pipe diameter, pipe surface roughness and the viscosity of the fluid being transferred. Minor loss – Head losses due to friction and flow disturbances within the system affected by components such as couplers, entry condition, bends, valves, filters, diaphragm etc. To keep things simple, we analysed the major losses in the system only as it will always be the predominant cause of pressure loss. With different fuel system setups differing from car to car and the type and number of fittings used, the minor losses cannot be determined accurately without physical flow testing. Since we are running the 2 feed pumps in parallel, the theoretical flow rate is just compounded. Remember, pressure is a resistance to flow. Figure 3 - Walbro 450 LPH performance chart (Walbro 2018) Analysis of the friction factor for turbulent flow inside a smooth wall pipe using Moody chart; (S. Beck & R. Collins, University of Sheffield 2018) From the two intersecting lines above, we can find that the friction factor is approximately 0.048. Conclusion The theoretical, calculated value for the pressure drop of 31.5 psi strongly correlates to the 35 psi observed on the vehicle. Bear in mind, that only major losses are calculated, safe to say the remaining 3.5 psi drop can be attributed to minor losses in the system. So, how much flow can the stock fuel line take without too much pressure drop? Well, it highly depends on what you define as "too much" pressure drop. We set an expectation that the fuel system should not have more than 8 to 10 psi drop between the fuel pump outlet and the regulator. Working backwards with the equations above in the instance of running the same Walbro 450 LPH, we find that the maximum flow rate shall not exceed 0.000066 m³/s (238LPH). This is equivalent to running a single Walbro 450 LPH pump at 95 psi! Moving forward, the next step is to upgrade the fuel lines to AN -10 size (~12.7mm internal diameter) and increase the boost to 35 psi (however, we expect that the turbo will run out of steam before this). The base fuel pressure will remain at 55 psi with the two existing pumps blazing and the fuel pressure at the regulator, at full boost, should be at 90 psi. At that pressure, the twin Walbro pumps should be able to flow 536 LPH (0.000149 m³/s) with a pressure drop of approximately 1 psi due to major losses. Minor losess within the system should also decrease as all the fittings and liners in the vehicle will be converted to AN -10. References Curtin University. 2015.

Hi, we sure do international shipping. I would like to confirm that you are in Curacao? We have express courier shipping available to Netherlands but it doesn't seem like it is able to deliver to Netherlands Antilles. We have to opt in using Australia post (still express but may takes longer because due to remote location) RB25DET S2 full kit is available, email us with your request and option you choose and we will reply with the shipping rate Thanks

The RB25 NEO kit are under development as we speak . We know the kits we sell will perform but we have to jump few hoops in the design to make the NEO kit look good, price conscious and give options for those who run FFP or stock J-pipe with the 'traction control' throttle body. We will update the status from time to time in our FB page.

5-0 Ignite is proud to offer SAU members and Nissan enthusiast an alternative option for 100% plug and play coil pack upgrade, utilizing Audi R8 coils, that are known to perform without breaking the bank. We aim to solve common problem of spark blow out at high boost levels as often experienced by many owners which often resulted in dyno down time, performance/efficiency sacrifice, running ridiculously small spark gap and associated costs. We were hugely satisfied with the R33 GTR test vehicle running our kit which yielded 603 whp @ 27 psi with off-the-box 0.9mm BKR7E spark plug gap with plenty more to go, more on that here: https://www.50ignite.com/blog/technical-blog/coils-aint-coils/, (we couldn't achieve this on the previous 2 different brand coil setup). All of our products are designed, manufactured and tested here (except for other manufacturer's buy-in product) in Perth, Western Australia. We are slowly expanding our product lines with items that we consider as 'worthy' or supporting upgrades. For now, we have these kits on offer: R32 GTST - RB20DET R32 GTR - RB26DETT R33 GTST - RB25DET S1 R33 GTST - RB25DET S2 R33 GTR - RB26DETT R34 GTT - RB25DET NEO R34 GTR - RB26DETT S13/S14 - SR20DET S15 - SR20DET Check out the full product line on offer here www.50ignite.com at introductory pricing. Additional information and features Our RB to Audi R8 coil conversion harness features; 100% Plug and Play. Remove your old OEM loom from the connectors, plug your new one in. Bypasses the OEM igniter completely (where applicable). Teflon F.E.P wire insulating material capable to withstand higher temperatures than OEM PVC insulation and resistant to most oils and chemicals. 2.0mm2 wire conductor cross section area for the constant power and power ground. 1.5mm2 wire conductor cross section area for signal and signal ground. OEM specification weather proof connectors. P.E.T wire braided sleeve and connector boots. Heat shrink with built in glue for good adhesive strength. Professionally crimped terminals. Separate power ground and signal ground terminals to avoid ground loop. 2-step cross-checking process, bench tested and tagged to ensure a guaranteed start and product traceability. If you have made variations to your setup (i.e. engine conversion etc) please check your ignition loom and cross reference the main connector to our pictures on the website. Should any part of the loom be close to any part of the exhaust, it must be moved or sufficiently protected from thermal damage. We do not incorporate a wire loop in our harnesses for use with an inductive timing light as our experience proves it to be an unreliable source. To set ignition base timing, we recommend the use of coil on plug extension lead (such as DAT-Equipment TE010 or the like) to latch your inductive clamp onto for a much more reliable reading. Our RB20/RB25/RB26 conversion mounting plate features; Direct bolt on with all fasteners provided. Coil packs can be removed individually from the mounting plate when installed. Correct indexing of coil pack placement. Provides lateral support on the upper body of the coil pack (removes dynamic bending stresses on the fragile spark plug in comparison of when no mounting plate is used). Precision cut Aluminium plate. Stainless steel stands. Incorporates loom holder for a clean ‘tucked’ look. The coil packs we feature; 100% genuine Denso Audi R8 ‘smart’ coils.
