984 is around 300rwkw

044 is around 400rwkw

040 would be close to 984 in output, so it could be droping at 260rwkw if thats a low reading dyno.

best bet is to use a standard pump or the 040 to feed a surge tank and use either single external 044, or twin external 984's.

have you had a pressure and flow guage on it to confirm the flow is dropping at max power?, you could have a restrictive ot blocked filter etc...

The 040 flows 220-240L per hour which should support somewhere in the vacinity of 400-500hp.

I'm getting 450hp on one that is 3 years old at the moment. Are you sure it's the pump that has failed? I have seen regulators fail in the same way....rare....but can happen.

well i put a 280l/h sard intank pump in today and run 302rwkw before it ran out of fuel also. that works out at about 550 flywheel horsepower, which is about right. 260 rwkw works out at about 470fwhp which is also about right for the 040. so i guess i have learn't alot about fuel pump limits during this build. what pumps are other people running?

    • Has equal chance of cleaning an AFM and f**king an AFM. I think you can work out what happened. When the Hitachi ECU sees the AFM die and goes into the associated limp mode, then it will start and run just fine, because it ignores the AFM and just runs on idle maps that will do what it needs to get it going. But there is no proper load signal, so that's about all it can do. My suggestion? If you don't want to go full aftermaket ECU, then get some R35 GTR AFM cards and some housings to put them in, in the stock location, and Nistune the ECU. Better to do a good upgrade than just replace shitty 40 year old tech with the same 40 year old tech.
    • So my car was recently having trouble starting on initial crank, I would need to feather the gas for it to start up but besides that it would start and run fine. So I clicked the idle air control valve (with throttle body cleaner) and cleaned the MAF sensors (with MAF cleaner). The start up issue was fixed and now the car turns over without the assist of the throttle, but the car is in limp mode and wont rev past 2.5k RPM. From what I understand the IACV would not put the car in limp mode, so I am to believe it is the MAF sensors, but it was running fine before and now I cant get it out of limp mode. I cleaned the MAF made sure the o rings were seated properly. Made sure the cables were plugged in properly, the cables also both read the same voltage. Does anybody know why this is or what could be causing this or how to get it out of limp mode?
    • Ooo I might actually come and bring the kids, however will leave the shit box home and take the daily
    • Thanks. Yeah I realised that there's no way I'd be able to cover the holes with the filler, it would just fall through. Thanks again @GTSBoy!
    • That was the reason I asked. If you were going to be fully bodge spec, then that type of filler is the extreme bodge way to fill a large gap. But seeing as you're going to use glass sheet, I would only use that fibre reinforced filler if there are places that need a "bit more" after you've finished laying in the sheet. Which, ideally, you wouldn't. You might use a blob of it underneath the sheet, if you need to provide some support from under to keep the level of your sheet repair up as high as it needs to be, to minimise the amount of filler you need on top. Even though you're going bodge spec here, using glass instead of metal, the same rules apply wrt not having half inch deep filler on the top of the repair. Thick filler always ends up shitting the bed earlier than thin filler.
