Tuned..... 1002hp R34 T88gk 18cm Monster!

[The Dan]

every single engineer knows this.. are u one?? i would say not.. am i?? most definately

Let me see. hmmm oh wait, the next post is a doozy

why not??? a commodore runs plugs in the 15 range... they run fine hahaha

There it is. That's the gap, Every engineer knows this....I'm a better engineer than you

correct...the more power a car generates the more a drivetrain is stressed and the losses i.e. heat is generated.

where was a 500hp drivetrain loss mentioned in anything but your own post?

im not getting all "bent up about it" just can't get my head around 1000cc injectors making 1200hp on Sunoco...thats all. If something clearly doesn't add up to me i ask the question...is that ok?...Just because i didn't line up with the back slappers on the first 3 pages doesn't mean im not impressed...around 800hp is what i estimate the car will roll at Autosalon. Please prove me wrong.

If you kept losing 20% through the drivetrain you would never be able to make power.

Guy A makes 2000hp through his RB25 drivetrain to the wheels. That would mean if there was a 20% loss that his engine is making 2400hp.

Guy B makes 300hp, same drivetrain. He loses 60hp.

Heat does not cause the loss of a further 340hp for Guy A. And by your theory, Guy A would make 2340hp at the wheels until his drivetrain heats up, then it's back down to 2000hp for him.

1000cc injectors should be capable of exactly 1200 engine hp. Considering he would only be making 1100-1150 engine hp...it's high but not impossible.

I wanna know how it can drop off so much torque at the top and keep climbing in power

The torque scale has been zoomed in on a bit which will fudge the relative drop a bit, if the numbers on the Y axis started at 0 then it'd probably look markedly flatter. The Dynapack software focusses the chart on the range of lowest to highest read value for torque and power to allow far closer analysis of the data provided, but invariably makes torque and power curves look more violent than they really are.

1000cc injectors should be capable of exactly 1200 engine hp. Considering he would only be making 1100-1150 engine hp...it's high but not impossible.

It all comes down to the fuel being used, the fuel pressure setting and the air:fuel ratio. It is impossible to make blanket statements like the one above.

Think about it for a minute. What power would those injectors support at 60psi base fuel pressure but running Methanol? How about oxygenated leaded race fuel? PULP?

It might be a good general guide to say that 1000cc injectors could support 1000 engine horsepower at 45psi base pressure and 12.5:1 but to make claims about any particular setup's capabilities without knowing the fuel type used, the pressure, the air:fuel's and the injector size is foolhardy at best.

Here we know that it was running 1000cc injectors, I've had a 'stab' that it's running Sunoco MaxNOS (as it's the new hotness;)) but we don't know the fuel pressure the reg was set to or the AFR's tuned to. Let's say 13:1 and 65-70psi should be enough.

Possible but more likely that the 1002hp is a great indication of flywheel horsepower.

The terminal speed on the timeslip (if this car ever makes a full noise pass down the quarter) and the race weight of the car will give a better, more 'real-world' comparison and idea of the power the thing is making.

***EDIT***

I had to laugh at the genius of an engineer above too!

straight percentage loss again..... if a 2kw heater can heat up my bedroom by 10 degrees in 10 minutes, then in theory an 800rwkw car losing 20% through the drive line would be dumping near enough to 160kw in heat at the point of peak power (you don't lose energy, it must go somewhere, in this case heat and noise). The cabin would be pretty unbearable to be in after a couple of pulls on the dyno don't you think? The gearbox and diff would be glowing....

After an hour the whole workshop would be on fire

@ the Sooky lah lahs !!

Good effort Trent.

Now put the 22 on it, get some more injector, hold the gate shut and let it rip for Salon !

u must be on drugs... never be able to make power?? u will always be able to make power.

Cars run on a loss, but make power.. the only time u wont make power is when ur drivetrain loss is 100%

which will never happen.. unless it breaks..

oh and btw, Dirt nor i said its a Fixed percentage loss...

...

What a facetious argument.

[Swiper the Fox]

This car almost makes more power (30hp less) than John's RH9 GTR built by Croydon racing that runs bigger injectors, the same turbo with a larger rear housing, more boost and a two stage NOS system (fogger and direct port) That won the power championship at Autosalon final battle last year.

Truely an achievement considering the years of development and $$ poured into that car.

Ben...pass the tissues.

yeah, but rh9 stickers add 100hp remember!

srsly tho... great result mate

if i ever need roofing tiles moved FAST i'll know who to call!

[PM-R33]

Wow this thread got extremely heated over the last day! The % loss drivetrain issue over a fixed amount has been debated to death! Keep it on topic, i don't want to see this thread locked

[Guilt-Toy]

is there a course i can take to become a engineer ? I feel like i am missing out

[joeyjoejoejuniorshabadoo]

plenty of courses... just be sure to attend every class and dont miss spark plug heat range 101

[Guilt-Toy]

who is heat range? and what is he doing in my spark plug?

[R31Nismoid]

ah drivetrain losses

[2rismo]

who is heat range? and what is he doing in my spark plug?

Never met him myself but he reports to General Automotive.

[shanef]

i take it its using an 'rb26' base then to use the hks hi deck? them things are rare as hens teeth too

cheers i reckon i will see the 22cm come in sooner or later, but yeah it seems everyone is a critic and quick to judge... kinda kills the fun outta playing with cars... as for the injectors it turns out they were most likely indy blues... but hey i have already been shot for guessing they were blitz 1000cc (also blue in color) .... them the brakes.

Awesome job, not matter what the nay-sayers bring to the forum. Stop reading if it kills the fun out of playing with cars, just go and play with more of them instead...
