Fatz Gtr Reliability Testing

[niZmO_Man]

Just go back to 98 Or swap cars before burning it to the ground.

PWM controlled, so depends on how it's getting driven, on track its flat out

Rail returned to surge or main tank?

[fatz]

I can't see why the surge tank would be a problem. You may not be happy with Brad but that doesn't make his aluminium corrode. Plus I've been running one of his tanks about 12mths longer than you without any issues, there are plenty of them out there.

I think you need to look somewhere else. Feel free to point and laugh if I'm wrong

everything has been replaced

and now i can trace the source of the shit due to the multiple reusable filters

and there is definitely gritty alloy like stuff coming out of the surge tank

either way i will pull it apart and find out if its the problem

and put a fuel cooler on it now

Brad had a bad habit of not cleaning out his well-crafted parts properly and maybe that could be your problem big fella. I would stick with the fuel you are using,,,it has to come good sooner than later.

I have a purpose built fuel cooler off an X5 3.0l Diesel that you can use tiger. I currently run one on my car and it works a treat. Here's some pics for your love.

Here is it fitted to my car

Nice and new straight out of the box,,,waiting for some R33 GTR sex.

Plumb this bitch straight into your return line and cool that fuel baby.

Cheers

Neil.

Hi Neil that fuel cooler looks to be exactly what we all need to keep fuel temps under control.

Time for a group buy.......

Surge tank, it has to because the main pump out flows the Walbro E85 lift pump even after it has been slowed down

[XKLABA]

The Mitsubishi Magna of some year has a oil cooler that look exactly like that just a bit bigger and threaded inlet/outlet for those of us that are running AN fittings and PTFE braided hose, will look for pic

There are some fuel cooler pics on this page -

Not sure if its helpful or not.

Thanks for that mate, I looked before but gave up cause to many pages lol

So that is just a regular 23 row oil cooler with a custom air duct/protector ?

Looks very nice and neat

Yep, it will need some relocation or modification if i ever get around to doing underbody aero stuff... Its not really copping any air due to the diff being in its face but the fuel pumps have been nice and quiet since its been fitted so its certainly doing something, since the issue has been sorted we have not bothered logging fuel temps etc...

Neils compact design is probably a lot more practical and obviously more cost effective

[fatz]

yea baby ill give ya a bell longing after a few cans

[fatz]

so last track day i noticed that after a few laps she started to get lean
and after about 6 hards laps would develop a missfire

so naturally i though my fuel was clogging my injectors again
checked them at the track and seemed fine
had them flowed and they were fine
anyway the internets told me when e85 gets real hot it leans out
and i decided that my surge tank was running dry ( its only about 1 litre and a average design)
the insides of the cheap alloy had ben oxidising and running thought the fuel lines as well
old setup

ill stick it on my r31 i think as it loves fuel surge

so fuel setup number three was drempt up

biggest walbro you can buy for the intank

alloy 2.5 litre tanks( anodized so it does not corrode)
trusty twin o44's


booked in for the skynats at winton with two drivers and this thing drinks fuel so will go the flex setup so i dont have to buy 18 jerry cans

[SimonR32]

Have you tested the fuel pressure? 044s have been known to shag out with E85

[fatz]

have fuel pressure protection and fuel temp now as well

[fatz]

when i say going lean

first lap 12.7

thrid lap 13.2

5th lap 14

back to pits and let her cool down and she is back to normal

its not a sudden massive lean out

[Piggaz]

Good old warm E85.

Boooo!!!!

[niZmO_Man]

Like warm beer...

[fatz]

place ya bets for the 98 tune

[fatz]

15psi= 280rwkw

19psi= 319rwkw

shows ya the love that e85 gives

e85

17psi=340rwkw

flex tune tomorrow then pack her up for winton

have not been to a new track for quite some time

should be fun

[Piggaz]

Winton is sick! Bit tricky around the "boobs" up the back. The "flip flop" then belt up the hill is mad too... Just don't look at the concrete wall on the left hand side. Haha!!!
