What is the 04 HP rated at by Infiniti?

 

Wow I would love to see what an 05 would do on the same dyno. I bet it would be really close to those numbers. It really does seem like the 04 engines were underrated. I wonder how different an automatic would be though?

 

Your sig says 04 6MT, but the dyno chart says 05 G35; so please fill us in on the details.

 

Keep in mind this a Dynopack dyno where the dyno connects directly to the hubs (ie remove the drive wheels) and that they are correcting the power to flywheel numbers and not wheel numbers. All dynos read differently. I would bet you $20 that if this same car was dynoed on a Dynojet, it would put down about 230-235whp which would be considered normal.

There aren't freak VQs out there. They all run and dyno within a few % of each other. This isn't the 60s anymore, the tolerances are too close to have big swings in power between like engines.

 

I typically agree with this as well. All the motors are extremely close from the factory. The discrepencies seen between one stock g35 to another are because of factors like temperature, dyno equipment including the fan, humidity, etc.

I have seen a stock G35 6MT (2004) put out 245 WHP but again it could've been a lucky day.

 

He already admitted this was BS in another thread...

I think he just decided to give up defending his statement. I don't see why one shouldn't believe him. Like DaveB said, on a dynapak those numbers aren't really special.

 

On the folder wich the file was saved it says 05 g35. On the top is my name and 04 sedan.

 

There were about 3 05s 6mts. The best they did was about 270. At the same time there was 1 04 6mt coupe that did 245.

BTW Im talking all stock cars.

 

As mentioned, dyno's differ from one to another. Some read high... some read low. They are useful from a comparitive standpoint.

If there really were freak VQs out there, I would want to see some 13.8/103 passes on the quarter in stock form...

 

Wait till december

 

These are direct flywheel numbers ... not at "at the wheel" numbers. So basically 260hp/260ft just like published by infiniti. The drop down doesn't occur until you measure at the wheels, which are the dyno results we're all used to seeing

 

TBone24 I think you're confused. The only way to get TRUE engine/flywheel HP is to strap the engine ITSELF to an engine dyno. This is not something anyone ever really does because it requires removing the engine from the car.

Typical Dynos we see are wheel dyno tests. This means you strap your car down on a big roller/drum and it measure the horsepower to the ground.

The dynapak in question here is different in that you take the drive wheels/tires off and connect the dyno equipment right to the brakes/hub. This means you're cutting out the rotational weight of the wheels and tires (anywhere from 40-60 pounds per wheel/tire). This means the power is registered higher. However, it is still far from flywheel horsepower as you have transmission, driveshaft, differential, etc. loss involved.

 

....and to go along with what Brian said, for what ever reason, Church's decided to correct the power to flywheel hp/tq. I guess I don't understand why they did that. Maybe Dynapaks state "flywheel", but they really mean "at the hub".

I'm by no means an expert when it comes to dynos, but I do know that Dynapaks are brake-style dynos (ie they can adjust load) and that they generally read about 15whp higher than a Dynojet. When it comes to Church's dyno, their numbers are always significantly higher than almost any other company's dyno. That's really not a bad thing because all you should be concerned about is the gains and losses you're mods are making. I could care less if Joe Blow got 270whp on the Dynapak with his stock 04 G and I got 220whp on the Dynojet because I know that a dyno is tuning tool, not a device that generates numbers I can jerk off to.

I should go on to add that the 1/4 mile ET/MPHs coming from the cars dynoed at Church's show absolutely no indication of being quicker or faster than any other G35s with the same mods that have dynoed 20-30whp less on the Dynojet.
