Why did u upgrade your pump? Making more power or for safety factor?

i wonder how your numbers would compare to a larger capacity v8 (i.e. 6.2ltr, ls3) which makes the same peak power...would be interesting to see if your 2.8ltr makes more power & torque @ 4krpm

wow! looks like a gain of 50kw @ 4krpm! must be happy & must be hanging to drive it so with the gtrs's u were making 200kw @ 4krpm & now you are making ~340kw with -5s & latest setup what is the difference in the run with the blue line v's the brown line (in the 1st graph) or is it just 2 runs where you were trying to diagnose the miss?

That's pretty impressive Dean. Are u running a relay on the factory wiring? Have u tested the pump to see how much more it has got and what it could potentially support in terms of kw?

thanks for sharing - now makes more sense as to how my oem pump supported 365awkw..."Nissan R33 Skyline GT-R stock. This factory Nismo fuel pump was tested to flow 252 lph at 43 psi and 13.5 volts."

update. i spoke to efi performance today & was advised that all i need to do is run a '-10 push lock hose' between the pump inlet and the filter & job is done i asked about retaining my intank pump & running the pierburg inline without surge tank (under the car)...not a good idea as the pierburg will run my intank dry hence best that i remove the intank pump & run the new pump intank with the removal of my surge tank/044 setup. they ran a car tuned on e85 making 500whp & didnt hit the limit of the pump (e85 needs approx 30% more flow). they also ran this pump on multiple cars making over 500kw atw with 98 & have never hit the limit of this pump

thanks I've emailed EFI and I'll call them tomorrow. If I have no luck, I'll be in touch

i bought it from efi performance. i just noticed that the supplied fuel sock doesn't work, the mating diameter is about 5mm too large - where can i source a fuel sock, any ideas?

And now I understand why you don't have surge issues Dean...I took the entire fuel pump holding bracket & harness out (which sits in a track at the bottom of the tank) & now I am much more comfortable about running just an intank fuel pump. The OEM system has a surge tank which by my calculations holds just under 1 litre of fuel & this is constantly replenished by the return line which is the black fuel line in the pic with a zip tie on it. The return line runs directly back into the base of the surge tank & obviously if the tank has more than say 10% fuel, the height of the fuel line will also overflow into the surge tank from over the top which is the opening where the fuel pump sits in its cradle. Verdict? Under car surge tank is coming out & my 'Bugatti Veyron' pump will replace the OEM fuel pump...not much modding required to make this work.

I have now confirmed it is an r32gtr pump but can't find the flow rate on this unit...I'm still baffled /surprised that it supported 365awkw http://www.nengun.com/nissan/skyline-fuel-pump-bnr32-genuine-217055

hi guys, curiosity got the better of me so i decided to pull my intank pump out...how did this pump support 365awkw when i had the car tuned back in 2004 (2.6ltr bottom end with sard 700cc & hks gtrs turbos)? how is this possible as it looks like the oem pump to me - can someone pls confirm if this in fact the factory pump for an r32 gtr? i did have the relay added to the fuel pump harness wiring to increase the voltage but that was it - hmmm

Hehe last few posts are funny U gotta drive and enjoy these cars, although, I unfortunately hardly drive my car...due to a somewhat 3 yr old, 10 mth old and another on the way YIKES

luv the carpet in the garage reminds me of my garage and actually comes in handy when under the car

I'd like to see what gtx's @ 5k make on a similar setup

Funnily enough Roy, I just had a chat with Sean about his perspective on the GTX's vs 2530's vs -5's...I'll let Sean explain it

when are we all going to get together for an ADM cruise? i know that logistically it wont work for some people BUT this would be a once in a lifetime opportunity to round up as many ADM's possible which still exist is this a feasible idea?

Nice 'Datsun' Harry Very neat

is anybody familiar with this ADM? it was by fluke that i came across this example on google images

Here it is from my workshop manual its got its own little pump & interestingly enough, the core is an Earls item (well, it is an ADM GTR so what would u expect as these were fitted locally before sold)

4 yr thread bump haha...this is why I like sau, if u dig deep, in most cases u will find your answer

Thanks for the info Nick I actually need to see what my intank pump is, fitted back in early 2000s but it did support 366awkw back in 2004

couldnt agree with you any more anthony - im getn my drink right now

Knighty84, very tough and clean. Reminds me of my previous red gtr...the n1 lights and lower lip set it off! How much power is it running?

I'd rather not, it has oem mounting brackets and fittings

I might then try relocate the surge tank so that I can get my oil cooler back in for the driveline
