Terry speaketh the truth

I look at it in this sense: if someone claims they make "XXX" HP on a dyno, then they run a time of "XX.XX" at "XXX.XX" mph which doesn't jive with their "XXX" HP, then they "should" know that the dyno number is untrue. After factoring in certain conditions, of course

 

I dyno'd 278 whp with stillen exhaust, hfc, gen 2 intakes... 17" tires. I'm now running with 19" tires and minus the intakes. I also use 93 octane. What do you use?

265 is a good number though, probably on par with what i've been seeing locally.

some say they are dynoing 300+ with Technosquare on pump gas but I highly doubt that

 

Good to see someone with a X get a tune.. Good numbers. I have R2C intakes( Going in tomorrow) and Berks HFC I hope a see a little higher of a number when I get mine tuned..
HFC's> cat back

 

Still don't understand how HR Z's are getting well above 300whp with simple bolt ons yet we're stuck with 280-290whp max.

 

drivetrain loss?

 

How much of a difference is that? It's a pretty big difference in whp. around 30whp at least.
Anyhow, I know the Z comes with a carbon fiber drive shaft, other than that, everything is the same in terms of drivetrain.

 

From what I've been told with auto trans we're losing 10-15% HP from engine to rear wheels... and AWD is worse!
and i'm still trying to debate over r2c versus injen cai --- ahhhhhh

 

I understand the drivetrain loss on auto and manual, which BTW is actually around 20% for auto and 15% for manual. what I meant was how much of a difference in percentage between an auto HR Z vs. an auto HR sedan? (or manual vs manual for that matter)...

What I'm wanting to know is how there is such a big difference between the HR Z and HR sedan in terms of power output when there is no difference in the engine and the only drivetrain difference is the carbon fiber driveshaft vs. the metal one in ours.
But even then, does loosing drivetrain weight add hp or simply increase response? I mean surely changing to a lightweight flywheel wouldn't actually increase max whp would it? If that's the case, then even the light weight drive shaft in the Z wouldn't make a difference in power. Is it the ECU then?

 

The light weight flywheel actually helps b/c the force it takes to spin the flywheel is much less which in turn "robs" less hp to the wheels. I have noticed even with my hardly modified 06 g coupe 6MT that my clutch feels like it slips a little under very heavy acceleration, (easiest to feel it if going up a steep hill at 15mph and stomp it) so I do believe if anyone with the 6MT would just order and install a better clutch that you would see much better numbers on a dyno. But this is my opinion. Anyone agree?

 

Are those nickel chrome, black chrome, or just polished R2Cs?
