R33 GTS 511rwhp-Stock injectors DYNO

[R32-GTS]

But its done it on about 5 different cars now so maybe its not luck ?

Maybe u just need to come over and see it for yourself.

[R31Nismoid]

im coming over.

23rd Nov.

im going to start a thread about it later in the week.

[R32-GTS]

Nice , just hope your not as arrogant as some of these other fellas.

[BU5TER]

arrogant?? where??? is it because we drive our own cars over here

[R32-GTS]

haha brad. whats that . you want me to drive your car for you ?

[BU5TER]

hahaha Simon nah they breed them big over here and we like to drive our own street cars thanks anyway for the offer

R31Nismoid aren't you friends of sst steve's family hahaha

[R31Nismoid]

nah man im staying with Steve/Bayley actually

[R32-GTS]

Yes, you definetely are big.

[RB20LagWagon]

Hmm see i would have thought arrogant would have been the best way to describe sst-steve

[pnblight]

Oh my god i feel ashamed to be west aussie, How can please some people lay in bed straight at night.

I hope the rest of ozz doesn't judge us all in the west the same as few intent on making a joke of us.

Is that because you guys don't use Jim Berry clutches or because we drive our own cars at the drags :spcow:

Which 5 cars is that? Doesent the laws of physics/maths apply in WA??

then why does everyone suggest not running above 90% duty cycle?

If the injector is running at 90% then there is insufficient capacity left for acceleration enrichment. When you push the thrott le down the ECU adds more fuel for a short period of time to help the engine accelerate. If you dont add any fuel the engine will hesitate and only slowly accelerate.

If the injector is running at 90% then there is insufficient capacity left for engine temperature enrichment. One of the ways to cool down an engine is to add a bit more more fuel. That is not possible if the injector is already running flat out. One of the things we do with the V8SuperCars (that why they trail flame out the exhaust on overun. We add extra fuel to cool down the cylinder heads, you can see the difference on the data logger.

If the injector is running at 90% then there is insufficient capacity left for engine protection. If you program in some protect strategy for overboost, excessive air flow, high water temp etc there is no extra fuel available to save your engine.

In an extreme case there may not eve nbe enough fuel for cold run enrichment. Without extra fuel until the engine warms up it will run like a dog, stall, may not start and generally be real pain in the ass when it's cold.

because thats what smokes the coils in injectors... an injector running over 90% d/c will get too hot and eventually fuse its coil..

Actually the fuel flowing through an injector is what cools it down. So it could be argued that more fuel through the injector = cooler running.

that is a load of crap. A injector holding wide open is not gonna overheat and burn out haha.

That's not quite right either, a solenoid is an electromagnetic device. Holding it open continuously does not allow any magnetioc field recovery time and it eventually won't close against the boost pressure. There is a big difference between 99% and 100% in that regard.

Hope that helps:cheers:

yes the laws do i ply but i think dynos anit dynos over here and i'm fast becoming a believer that the 1/4 is the only true lard stick as dyno figure seem to matter very little anymore with so much variation.

has magic1 gone down the 1/4 yet since it recorded the (true or false) figure of 511rwhp. I believe it went a mid to low 12 @ 120mph with 400rwhp (unsure of whose dyno) ???

265 rwkw (355 rwhp) = 11.9 at 119.8 mph in an R34 GTT

So 511 rwhp should = high 10 at ~130 mph

Ive read in numerous places that an injector over 90% will suffer the following

1. Coil overheats, the size of the windings in an injector coil are very small they were never meant to be on 100% of the time. Fuel flow cools an injector but being held at 100% the heat from the coils will far outweigh the cooling capacity of the fuel in the localised area of the coils. Leave them at 100% for too long and they will smoke.

2. At over 90% on almost all pintle injectors the injector will inevitably hit a static point were the injector hangs at half open half closed, which will actually have a hell of a lot less flow than an injector at say 75%. You do the maths high duty cycle then BANG into static half open position will cost you a motor.

Both are documented if ya wanna go hit google.

Peace

what kinda nut runs his engine at full throttle during warmup?

Magic1,

I think what you said along these lines might have needed some qualification to stop squabbles, you put some mega buck ecu's in the same basket when you say;

"....because the Wolf computer has far superior fuel management than any other compter full stop. "

Instead I'd suggest that the Wolf ecu 'may' have some advantages in fuel control over similar priced ecu's. When it comes to the Motec's and others it isn't in the same league but, at the price no one expects it to be.

FFS... All it does is to batch fire the injectors as it doesn't have sequential drivers for 6 injectors.

If that is an advantage, a lot of ecus in the market are a damn good thing.

Now, if Wolf is such a good piece of gear, why aren't we being educated on them here...? Why aren't we hearing the good points of the Wolf against the other ecus, similarly priced or not...?

I thought being the main Oz dealer, that's the best thing anyone could do...?

im coming over.

23rd Nov.

im going to start a thread about it later in the week.  

What do you expect to see when you are there Ash...?

Here is a premonition :

You are going to see a Gts-t pushing out ~430rwhp. Whopse farken doo... Is it a good effort ? YES. Is it unique ? NO !

Now, the BIG talking point here is that, it's done on stock injectors. Another whopse farken doo... What is the infatuation with farken stock injectors...?

Batch fire is an early form of injection where all the injectors fire simultaneously for each crankshaft revolution, so you have two squirts from an injector before the intake valve opens.

Now. there are arguments on the advantages/disadvantages of batch fire vs sequentilal fire injection. Sequential fire is adopted by all major manufacturers today, because of its positive effects on emissions and fuel consumption. Maybe, this should be more of the talking point, rather than "look... xxx rwhp with stock injectors."

I would love to see a Wolf dealer come out and correct the ramblings above, or even add to it.

Magic1,

Can you confirm your 120mph pass on the 1/4...?
