18% for 6mt and 20% for 5AT

 

I've got a 2003 "G" 6MT Coupe.

Mods:
TechnoSquare Crawford Reflash ECU
JWT PopCharger with "Z" Tube
Crawford V4 Plenum
Crawford HiFlow Cats
Crawford Headers
Invidia G200 Dual Exhaust with "H" Pipe
Ground Wires

My 3 pulls all gave about the same results (I'm the blue line)
The other "G" is a 2005 coupe, with a Motordyne 3/8" spacer, "Z" Tube, and a K&N Filter, otherwise totally stock. He's the red line.

whoa buddy, you are way off.......and show me where a EVO dyno's 241awhp. I would think they would put around 210 or so since awd cars have more DT loss.

The only car I can think of with about 5% DT loss is the Mustang Cobra 03 and 04 and the chevy Cobalt SS. When in reality they have more DT loss than that its just that chevy and ford underrated those engines.

 

I still don't get why you guys think this is a race car! What happen to luxury sport coupe? Can’t anyone just cruise this sexy thing without worrying how fast it is? ... or if the civic sh!tbox next to you is on the juice? WHY WHY WHY!!!

 

you think wrong, cause they do dyno around 240 @ the wheels

 

Further proof that the 05 280hp sedans don't make much, if anymore power than their 03/04 260hp counterparts. I don't know if Tony's 05 is a sedan or not, but either way it shows that he is making 226whp with the Crawford plenum which is what the 03/04s typically saw (222-226whp).

 

When I cruise, more people look. When I race, I lose. So I choose cruise over the lose blues.

 

The question is does the '05 280 hp 5AT is the same engine as the '04 6MT or is it an '05 6MT engine detuned to 280 hp? The '05 6MT engine has different intake runners, variable timing on both intake and exhaust along with different ECU. The 298 hp for the G35 and the 300 hp engine for the 350Z don't make much power with the crawford due to the different intake runners.

 

Great stuff. Very informative. Thanks.

I've always felt that my 300-horsepower car doesn't feel as fast as that magic number makes me think it should. (Yeah, I know I'm adding two horsepower. Sue me.) The '05 6MTs are champs at spec racing, but at the strip I think they're no different than the underrated '03 and '04 6MTs.

Nevertheless, it still feels pretty good to answer, "300" when the cut-to-the-chase question is posed to me. (So sue me again.)

 

As an FYI to complete the equation, it is a coupe.

 

Watch it guys, looks like I can take you in the highly competitive 55-60mph range.

 

Ive never seen a EVO dyno stock, but I was always under the impression that AWD cars put less power to the ground. Anyways that other guy was wrong about our cars losing too much power, that is about right.

 

How is the 04 HP curve better? Given that the redline on each is 400 RPM apart, and if we assume the cutoffs were at redline, then the 05's power curve starts to become higher than the 04's at about 5800-6000 RPM by my visual estimate. When examining power, the biggest differences will be seen in the range of RPM's you are in the most. When racing, you are typically shifting at or near redline so your lowest RPM will be where the biggest spacing between gears is. In most cars this is the 2nd gear shift. Since the 05 has a higher redline, this point will be higher in the 05 than in the 04. If you were to measure the area under the curve in each of the power bands, the 05 will probably net a higher number. This would equate to a generally faster car. The difference in HP at the mid and low-end is not really enough to make a huge difference in speed. Considering the 05 is better able to use a gearing advantage by staying in 1st gear longer(lower gears have higher torque multiplication), it would be putting more torque toe the ground overall. Assuming the same gearing in both motors, this would be true of each gear. The difference in power is not dramatic, but from a racing perspective, the 05 motor's curve appears to be more desirable.

 

That could be arranged between the same 2 drivers that dynoed above. Ryan, I believe is the 'better driver' (darn lucky young punk) so maybe Chaz would let him drive.
