true, I'm not in australia. what up there? your gas is sh*t ?

Our dyno's are realistic.

[Hadouken]

Your dreaming if you think you got 380rwkw from gtss on 18psi. Not even on e85

What 1/4 mile did you run? Trap speed?

Best hp per $

Move to the us lol

[tommis85]

Came across a fella on another forum today who reckoned he was making 300kw/400hp on 16 pounds with these Gave me the lol's

[Hadouken]

On a more realistic note, here is mine with cam gears

Cam Gears in and dialled up

Blue line before, Green line after

dont laugh, my mate is making 286kw @ 14.5psi with gt-ss

why only 14.5psi?

Hmmm interesting. But then and again I was making about 350hp with the ceramics at about 1 bar. I guess that with awesome turbos and an equally awesome tuner these crazy figures are possible.

Also, according to that chart flowing around the twin -9's are rated at about 560ps...but I'm pretty sure that's taken at the engine??? So if you were to account for drive train loses....you'd be getting back down to somewhere around the 480-500 mark. (don't know the conversion factor for ps to hp of the top of my head either....but i think they're fairly closer, a lot closer than hp to kw)

[tommis85]

why only 14.5psi?

Very true that one!

Anyone know what the -9 / GTSS sweet spot is....ie, their zone of peak efficiency? I'm guessing it would lie somewhere around the 18 mark as mine go beserk there....

[SiR_RB]

Why not?

He did make 320kw at 17ish psi but fuel pump was running out of flow and leaned out uptop, has alot left in it

[Hadouken]

Sorry if im being sceptical but, I will only believe it once ive seen the dyno plot of said friend.

Bit hard to believe when majority dont get that close.

[tommis85]

Well I'm working with a conservative 19-20psi to make 380-400hp ..... anything better will be a bonus on my unopened 17-year-old RB26

[SiR_RB]

Jez can confirm of said freakish results

[Hadouken]

Did he tune it?

what gear is your new dyno run done in? I assume all tuneres use same gear, as max kw at 170kph dosent sound to practical, I pretty much wanna know power in 2nd or 3rd gear at 6k rpm....if thoes sort of graphs are even avalibe? I haven't looked to much into the dyno grqph side of things yet

You cant be serious

Different cars use a different gear on the dyno for a 1:1 drivetrain ratio

Dafaq?

6k rpm at wot and max boost will see the same power no matter what gear it's in

[sydking]

Like i said, I assume, as im not sure, you did not answer my question, let's just say anything over 110 is useless, your dyno shows about 150 kw at 110....like I said not surw how these things work/read
