This was done on 5th gear, with Nismo CAI.

what did you pay?

What size wheels do you have? Also, how many pulls did you do b4 this pull?

Brandon@Forged

What dyno is this on? Looks like a dynojet. West coast Z's usually dyno about 10 rwhp less than east coast Z's (assuming both are on a dynojet).

Are these SAE corrected?

Manual or auto?

It looks like your A/F ratio is a little high from 2,000 to 3,300 RPMs...might want to get Technosquare or Altered Atmosphere to take care of that.

I paid $95 for two runs. Its a 6MT, I have the track model so they are 18" in the back. This was a dynojet and they used STD not SAE. They did mention that the car was running rich towards higher RPM as you can see. I have no idea how that can effect the dyno . I was pretty disappointed to see the numbers, but its one sexy a$$ car.

If your flooding the cylinder with too much gas, you won't make as much power. Clean up that A/F ratio and you may peak out another 5whp or so.

Those numbers do seem kind of low though. SAE correcting them could make them even lower, depending on the correction method used.

how many KM's (or miles) on the car?

in my previous car (honda prelude) i dyno'd when it was still new (ie 5000km's) and the dyno was low. but after i broke the car in sufficiently and opened up the engine (around 15000km), my dyno was up to par with others.

I dont know how I would correct the AIR/FUEL issue, perhaps a mechanic? I also have 28K miles on the car. I might have to clean the filter, i have no idea when it was last cleaned.

That A/F ratio has the flight path of an F-16. Isn't the mod list a bit short for such a dire need for a reflash.

Brandon@Forged

You have a few choices. You can get an ECU reflash or piggyback or even a standalone. I would just get a reflash.

Brandon@Forged

It should be below 14 through the whole powerband. Staying at ~13 would be perfect.

Lorca@Z1

I have noticed that the VQ35DE does not make peak power unless you make at least 4 or 5 runs literally back to back. Its strange, but the power just keeps going up until it finally levels off on the 4th or 5th run. The difference can easily be 15rwhp between the 1st run and the 5th run. Also, this is true no matter how warm the car is before hand. I'll try to post a chart as an example.

You should have tried in 4th gear. I made more in 4th than in 5th gear when I was N/A.

Dude! Don't be sad My base dyno with CAI and Borla Exhaust gave me 227HP and 217 TQ. Then today I dynoed my car with all the mods in my sig and got 243HP. Then tune the S-AFC on the dyno and got another 10HP, so total is 253 WHP. I was kinda dissapointed too. I will make another post with the graphs. It's dyno dynamic dyno and my car has 12k miles on it.

Lorca@Z1

1:1 gear ratio is 5th gear, 4th gear would not be an accurate measurement.

Here is an example of what I was talking about. These runs were made within a 7 minute time span and there was 5 minutes between Run #1 and Run #4, with 4 through 7 being within 2-3 minutes total.



This was on a G35C with a Tilton clutch and flywheel and CAI.

Yes but nearly 11 at redline is stupid rich. Keep it between 12.5-13.0 and your golden.

Those numbers almost looks like it comes from a "mustang" dyno.

The other possibilty is the operator isn't pushing the gas all the way to the floor, but this is pretty remote in happening.

fwiw, my experience at a recent dyno day in L.A. was that cars that were allowed to cool off prior to the pulls made more hp on the dyno than those done with a hot engine.

DomZ

What gear is closest to 1:1 in a 5AT...4th?

And shouldn't those numbers be SAE corrected?
