10:0 C/R in the U.S? That means it wont be 345HP like the Camaro's/ and TransAM's. They say on the Monaro website that the car will have 225KW. That means its only 301HP which makes me believe that this car have a 10:0 C/R against the 10:2 C/R for the LS1 here in the U.S. How else can they lower the power that the LS1 engine produces? What do u think guys?

 

By giving you a crap exhaust, A/F ratio & timing.
All fixed with $$$.

 

How about the C/R? Do they put another type of pistons? Thicker Gasket? How did they lower it?

 

Holden currently fully import the engine/transmission straight from USA in FBody spec. They don't pull the motor apart (except for warranty <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> ) all they do is have different exhaust manifolds, intake pipe & computer changes (more conservitive).

U have an LS1 engine right? Is it Auto or M6?

 

Over here or Dynos read in RWKW(rear wheel kilowatts), Mine prior to tuning made 160 RWKW.
Last time I gotit tuned it made 205 RWKW,
That doesn't mean much cause your Horse power is rated different to ours as well so best comparo is 1/4 times/speeds.
Our Holdens weigh approx 3,900lb's with a driver.
Stock they cover the quater in 14 - 14.5 sec range with trap speeds of 97mph - 101mph in std street trim.
Last time out I went 13.5 @ 105mph 2.2sec 60'
Only changes were shift kit auto, exhaust, CAI, and reprogrammed computer.
Next time out will be with 3200 Vig and U/D pulley.
After that I will have my TR 230/224 cam and further tuning.

That is really a shitty PCM. After tunning only 205RWKW=274RWHP without any parts?? What did u dyno after the exhaust,CAI, tunning?

13.5 at 105 with a 2.2 60ft is great. For sure after the TC ur going to shave another .3-.5 from ur time. And the cam will put u in the 12's.

 

I have a stock HSV GTO and after some tuning wasnt hard to get it to 304rwhp.

Also have to remember that we use different dyno setups as well pretty much all eddy current style.

I'll see if I can find out a conversion rate for this.

 

Normally you can add 15% to our dyno figures will the same as the USA guy's dyno figures.
