hey mate im going to be running aorund the same setup as you . except -5 turbos . what specs are you running on your head . and the walbro is it the only intank pump you have thats it ?

are you running different fuel rail and pressure reg ?

i dont know whether the -5 with upgraded actuators will see that kinda power on that setup anyone ????

Mine is a standard fuel rail with a Nismo regulator. Also running standard actuators on my -5s and its happy :)

really so just one inline walbro 450 intank how much boost are u running

and what power does yours put down at treads

im trying to get a build combination together that is tested and proven something that will deff work atover 400kw without any issues

I'm running the stock intank pump with external 044 and surge tank but I can't go higher than e60 as my fuel flow is just about maxxed out (I need to add a second 044), however, SIR_RB as above is running the walbro independent. I'm thinking of running my walbro as well on its own as it's now tried and proven for 450kw!

I'm making 430kw @ 25psi.

Standard fuel lines (only got e85 safe fuel hose to replace the factory stuff)

Standard fuel rail and fuel reg

Walbro 460lph pump running direct 14v with relay

No signs of it running out at my power level, running e72 (caltex eflex) has enough flow for 450kw at 25psi depending on AFR's, mines tuned at 11.8:1

My head has been decked, metal gasket with arp studs, greddy 264 cams and cam gears and brian Crower single valve springs, simple stuff realy

when u say direct running voltage with relay . are you using the standard wiring with ecu triggering the relay and just adding another heavy power feed from battery to 30 on relay and 4mm twin from 87 to pump

or are you running separate relay and triggering relay straight off igntion to have pump running all the time when ignition is on

cheers

no surge tank needed then ?? everything standard fuel lines etc except fuel reg upgraded and 1 in tank walbro 450 l p/h rewired correctly to supply 13.5 v at a constant without voltage drop when car is running .

Excellent. I was wondering how much my 400l/ph Walbro E85 pump could support power wise. I run mine ECU triggered through a relay and it runs at 14v. Running it as a single intake pump just like the factory setup it seems that it should easily support my 350kw aim on E85.

What size intercooler are most of you guys running for over 400rwkw?

We're currently trying to get more power out of my car but it's stuck at 360rwkw. It's a built 26 with all supporting mods, running -5's and e85. Something is restricting it and everything's been checked and it's all good which leaves us with the intercooler. Currently it's a trust 70mm tube and fin. I'd love 400rwkw or close to it if that's realistic.

Iv looked into plazmaman 76mm and apparently it's good for 800hp with new technology cores they use but not much info on them. Or am I better off with a Jap 100mm intercooler?? Perhaps even cams if that's what may be holding it back? What experiences do you guys have.

Any help is greatly appreciated.

    • Hello, sorry for being late to join the discussion, but my clock just died on me.   Ive tried to look at Michaels digital clock repair.docx and it doesnt work maybe the file has expired.   Please let me know if you can re upload it or take some youtube videos to show us how to get the clock installed? thanks
    • I thought that might be the case, thats what I'll start saving for. Thanks for the info 
    • Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated. Rb25det s1 walbro255 fuel pump nismo fpr holset hx35 turbo fmic 3" exhaust freddy intake manifold q45tb q45 maf   Re: s1 RB25det flooding at start up Fri Apr 12, 2013 5:07 am No, I didn't. I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.
    • Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
    • My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
