Gtr Fuel Requirements

[JET26R]

Hi all,

Just gathering a whole heap of info for my build and was wandering what fuel system setup (in detail) i will need..

pumps? how many,? what type

surge tank?

reg?

injector capacity?

rail?

lines?

anyhthing at all ive missed out on

absoluetly everything i will need to be able to run anywhere up to 550kw at 4 wheels?

Please only experienced answers from people who have the know how

Thanks heaps.

Chris

for 500kw at the wheels......

usually thats 2 Bosch parrallel fuel pumps.

Swirl tank

SX adjustable Fuel regulator

Apexi Power FC

1000CC injectors

Fuel system should use braided hoses

HKS fuel rails can handle this type of demand easily

heres a typical set up.... but this is just the fuel system, you need an efficient turbo, intercooler... adjustments to the air flow systems.

Decent drivetrain... usually 500kw gives you about 9 - 10 sec on the quater mile

thanks eeiko321 your a champ dude, you have the answer for every question ive asked. on the above photo can you label what all the lines are for me? and if there inlet or outlet etc. and where they go etc.

sorry to be such a pain but learning so much from you.

thanks again mate

By the way, where abouts in sydney are you located?

Also keep in mind that a setup like the one pictured has more money in fittings and braided hose too, something that people don't realise until their jaws drop when at the checkout counter!

And don't forget with that much power you'll be shearing 3rd gear like no tomorrow if driven hard!!

Here's another one FYI;

(R32 GTR)

-044 intank (lift pump)

-Twin 044's mounted on surge tank (undercar)

-Twin entry fuel rail

-1000cc's

-Adj FPR

-Earls fittings, lines etc

-Original supply line can be used as return to surge tank

As mentioned above, fittings will be a suprise.

The surge tank also is foam filled and has internal baffles. Basically fuel in that car isnt an issue.

he could be rich for all you know dude..

so this may just be a cheap excercise to him... who knows... not many people on here jump straight to 500KW at the wheels...

Im located in Sunny Auburn... where all the Broz and da Habibz live and the Couzzz as well...... lol

The swirl tank is also called a Surge tank.

here is an interesting article on a DIY surge tank

http://www.ratdat.com/?p=168

as per your request... Fuel system works with the surge tank with pump... here is a Schematic diagram on the run down and which way things flow.

http://www.sdsefi.com/fuelsys.gif

in my picture.. the fuel pumps you see...

The bottom side, where you see a Big Nut shaped bit is the INLET... and the one with the electrical terminals is the OUTLET.

as N1, mentioned...there are heaps of ways in doing things.. but this particular vehicle set up ive displayed was actually on an R34 GT-R done by a very reputable tuner in sydney

Croydon Racing Developments...

it was running Over 500KW at all 4 wheels, HKS 25/40 turbochargers with internal wastegates at 2.0Bar boost. with a 4-plate OS-Giken Clutch & Hollinger gearbox...

it has acheived 9seconds on the quater mile.

be wary at 500kw..... the stock engine internals will fry..... the GTR R32 gearbox is said to cope up to, 500kw...

hope this helps

cheers

Yeah agreed, although having a lot of money doesnt make parts cheap, just means less to that person.

Also, the more wealthy people i know are "tighter" than the average income people i know (to generalize)

Anyway, thats not the point, all the info in this thread is enough to build a capable fuel system, but i agree not many people go straight to that sort of power, hopefully this thread wasnt starte by someone on school holidays

well yeah...

the cars fuel system ive pictured was an R34 GTR... it had a Nismo Z-tune bonnet from japan which costed 10,000 AUD$

so whoever owns this car has money... or he could be just living like a SCUM or living with his parents and blowing every penny on the car.

i would personally never buy a bonnet that price...... but to some people ...the likes of DEMIR.. 10,000$ could be 1 cent in comparison to him....

yeah well he still hasnt told us why he is researching on this...

thanks eeiko321. youve answered all my questions, very helpful. look forward to hearing from you on my next question hahaha.

[DeCaY]

how much power is the stock R34 GTR box capable of handling?

[eeiko321]

how much power is the stock R34 GTR box capable of handling?

well not alot has been said about the 6-speed getrag on the BNR34

but generally "700Hp" ..approx 500 - 550kw is about the safe limit, anything over that..there is just no telling
