Got my car tuned at CRD results inside!!

[kabab]

The car has made 316awkw on 20-22psi (eBoost was fluctuating at anything over 20psi) on CRD dyno with the same setup plus cams.

Should be good for about 330awkw at 24-25psi with the 260/260 cams and proper boost control...

Don't forget the NOS !!!!

Don't forget the NOS !!!!

Oh yes... And a little extra "kick" in case anyone with a couple of GT-RS's tries to pick a fight

[Marko R1]

what boost is it running now out of interest?

23psi?

[Marko R1]

hehe...maybe i shall run 25psi myself just to lift the bar a little higher 380awkw+

i can then look at NOS to add icing

Marko,

I can't remember what the compressor flow map for the GT-RS looked like, but I'd be surprised if you couldn't run upto 1.8 bar (26 psi) on those babies

[Marko R1]

ive been advised the gtrs's will run up to 30psi :crazy:

but i love my gearbox & bottom end too much (engine that is) :looney:

[Merli]

30psi!!! DOOO EEEET!!!! :uh-huh:

It's all about how you look at things For example:

If you blow your gearbox, it's a good excuse to whack an OS Giken or a Pfitzner gearset in there

If you blow your engine, it's a good excuse to put in that stroker kit

See? That should be more than enough incentive to wind it up and see what she'll do :uh-huh:

I plotted Marko's torque curve against mine just for interest sake...

Marko's might be alittle off but thats as close as i could match em...

The GT-RS's are making 1000nm torque more then the GT-SS as they are both dropping off which should give considerably more top end!!

noice. one thing though. those graphs show N (measuring 'tractive effort') not Nm (newton metres). one of my pet annoyances...!

Whats the conversion from N to Nm ??

[Mik]

Whats the conversion from N to Nm ??

It's not that simple, one (tractive effort (N)) is a linear force, and the other (Torque (Nm)) is rotational.

Also, torque is affected by gear ratios.

Theorectically, if you multiply the tractive effort by the radius of the tyre, you will get the torque in Nm at the wheel, but this will be different to that at the engine.

Dynolog dynos somehow read torque at the engine, and they manage to do it quite accurately. There is one on the South Coast that read 390nm for a stock standard GT3 and just over 500nm for Gallardo.

yep, there is no simple way to convert N to Nm. it really pisses me off. would love to know how much torque my car makes.

Put in on a dynolog dyno

Put it on an engine dyno whilst you have the engine dropped to install sump baffles/extension

Hey guys,

Do you think my GT-RS on my sr20 will pull close to these figures hehe.

Its get tuned at CRD late next week...

I know that GT-SS don't make over 230rwkw on sr20's.

On the other hand I have seen a dynograph of 280+rwkw with a GT-RS on an sr20.

Its great to see some comparisons.

[Marko R1]

hi supergimp (dan),

this is because the gt-rs has a rating of 400ps whereas the gt-ss has a rating of 280ps...

you must respect the gt-rs...they rock as you would know mate!

I have posted up my similar experiance.
