fuel delivery in cc

[Patrolman]

Hi

newbie here.

just curious to know the fuel delivery in cc that the high powered cars here delivers, thinking of devonmickyboy, devonutopia`s cars, shadowmakers van etc....

I have a Nissan 2.8TD 4x4 myself, but it is great to read about your modified seat/VW cars.
my enginemods are, GT2871R turbo, 3" dump/exhaust, custom plenum chamber, custom injectors, more boost, FMIC, KN filter with ram pod, custom pump with 12mm plunger, Powershot LPG-kit, Snow Performance water/meth-kit, have not dynoed it, but the fuel delivery is set to 100cc per 1000 shots, std. delivery is just 45cc!!!

Cheers from Norway

Can't help you with the cc values, but just wanted to welcome you to the forum nonetheless.

What kind of power are you hoping for? Surely got to get it on the dyno as soon as possible!

Does vag com measure fuel injection in one of the measuring blocks? I could try and get a log if so.

I do know that my standard injectors are pretty much maxxed out which is why I have the lpg as well to give a little more fuel (and not sure whether my cam is squeezing more out the injectors too?)

yes devon it does, injection quantity.

group 15 or 16 in block 01 engine IIRC - maybe 20 ?

DAt is for petrol motors not diesels.

oooh no its not , u can measure fuel quantity on the dervs , well PDs anyhows

My van did originally about 45-50cc (got 186hp with 1,8bar), with R520 it did about 70cc (did 230hp with 1,3bar) and now it makes an even 100cc. These are measured in pump bench.

If you have a TD, not a TDI, these numbers don't count. It's something like 100cc on TDI = 150-200cc on TD.

I'm wondering about your turbo. That's nice piece for making top power, but how is your low end?

And please send us a dyno plot as it sounds really interesting. Nice setup.

Thanks for your answer shadowmaker.

My truck is a TD.

The turbo starts to boost at around 1600rpm, 0.5bar at 2000rpm and peaks at 2800-3000rpm (1.3bar). I wanted the powerband higher up, that is the reason for choosing the GT2871R, with .86ar.

The whole set-up is really good for top end power as you are saying also, spins 35" tires on moisted tarmac in 1st, 2nd and 3rd gear easily. Have no muffler, so quite loud, and exhaust exits ahead of the rear wheel, got better low down torque with the shorter exhaust and by removing the muffler(straight through type)

You should try a VNT sometime.

With that current unit, I'll think 1,8-2,0bar would be just fine.

I'm using GT3076R on my Volvo S60 2.5T AWD Automatic -04. Hopefully I'll get the engine running within this month. My goal is to get 500hp out of it...

What would the powerband be like with an ideally suited VNT turbo compared to the one I have today and how do you install a VNT in order to make it work properly, also what model should I have? some questions but it gave me something to think about

 

[shadowmaker]

With gt2359v (MB320cdi) or gt2559v (BMW330d/530d -04 older???) you should have something like 0,5bar @ 1300-1500rpm region and about 1,5bar from 1800rpm ->

These are capable for 1,75bar and 1,5bar respectively and both will be good for at least 250hp.

To make it work you just change vacuum bell to pressure bell (about 1,1-1,3bar) and make sure that with no pressure the operating rod rests against stop screw. Then apply a hose from compressor pressure side to the bell and bleed it (=the bigger hole you make on it, the bigger boost you are going to have). Don't exceed maximum pressures (1,75 and 1,5bar), as EMPs will go skyhigh!
