I think you may need to go external, although you can still mount the larger (2000hp) external pumps intank apparently.

With the G forces you are heading towards, you should be more worried about fuel surge... ;)

Lol. I want to do somthing along this line. But its way easier to just run a surge tank and as I plan to run 3 external pumps. 044's. Im planning on having the stock pump fill the surge tank and have it overflow back to the stock tank. Im hoping this will be good for about 600hp to the wheels.

Would think 2 would be plenty. I have one 044 in my car and its way too noisy - I'd hate to have 3 of them - there are better (and cheaper) options these days - but I believe yours is a track only car (or drags).

Having a PWM controlled pump is critical in a road car, so as not to overheat the fuel. Plus, not many of the larger pumps like running 100% duty for long.

Using multiple pumps without some method of making sure they are working properly is a good way to lunch an engine. I run twin Walbros, one feeds each V6 rail, so if one fails, the engine just runs on 3 cylinders.

Totally agree, and they are only rated for 70 hours life span on e85 apparently.

That's what I bought, Fuelab seem to be one of the only brands to have the speed controller built in, and I am pretty sure they can be mounted intank with an appropriate filter. No idea why you would want to though, at that sort of power you need the surge tank anyway.

I to am now looking at a Fuelab Prodigy pump, just a matter of which one is going to match my Weldon 2025-A closest, probably the 42401

Will mean I can run my PWM signal straight to it is simplify my wiring

Has anyone had one of these for any lenght of time ?

How quiet are they ?

      How do you go about diagnosing ecu's that don't have data logging, is it more experience at that point and just trying out things that you think will fix the issue?

      Stock O2 are basically useless beyond anything at stoich. Any misfire will also be seen as lean. The stock O2 also read a collective exhaust gas volume, not each cylinder. Sputtering and missing means not each cycle is firing, and some are. Which means even if rich, as shit, on cylinders as they miss, they'll read lean, but the cylinders that did fire will read rich, and combined, well, they can read anything from rich to lean.   Start with the basics before even going looking at sensor values.   Edit: I say the above, and that's coming from the guy with a few thousand dollars worth of scan tools sitting right beside me right now that I use frequently for my job.

      I just finished up a manual swap and I have a 1999 S2 AWD automatic in my garage, depending on where you are located. I'm in the the midwest of the US.

      I’ve heard it can be done, you need to redrill the holes where they bolt to the chassis and apart from that they are the same. I’ve never done it or know anyone personally that has, it’s just something I’ve heard

      If it's reading full rich prior to a misfire that gives one directional hint, if it's already reading lean, etc. If it's reading pretty cleanly stoichiometric then suddenly drops out from a misfire that suggests it's not air mass estimation that's the problem. Could be ignition, could be something more subtle. Could be the CAS has decided to start dropping out at random or the drive pin is worn leading to excessive lash and trigger errors. LTFT can tell you the same but it's slower to react and if this is a recent issue it might not have stabilized. STFT stuck in one direction vs fluctuating back and forth can be used instead but I like to read O2 voltages anyways and interpret directly. If the O2 voltages make no sense in general or are super slow to react it could also be a failing O2 sensor. There's no real error correction for failing O2 sensors in these cars.
