Dyno! Invidia Gemini, ERZ hfc & Injen CAI
 

Guys. I just dynoed my car and I was wondering if these numbers are far good or bad. Air/fuel ratio safe or what? Any opinions?

Here's the graph

Here's the video

I think it's low. I would expected around 300-310 on a dynojet just based on other I/HFC/E combos seen on the forum. But I'm no expert.

Looks like you are locked in right around 13:1 AFR -- that should be perfectly safe and actually about optimal for best torque.

Was your car tuned, or is this untuned, just bolt on's?

Another man from the town:tup:. My car is untuned buddy.

I think so too.. Its hard to see but your A/F looks fine

I just had all these three installed 2 weeks and got like 100 miles on them. Maybe it is too early to have a dyno? Or I should have waited a little bit for the ecu to come up with my mods. I dunno sorry for being noob.

Hard to really say but 100 miles and after the pulls should be enuf.. You never know maybe his dyno just reads low. You'd have to have someone else dyno their car there also.

yea that is odd.. i pulled 9 more on a mustang dyno and im still on the stock tune. Maybe it does read low, but that would seem out of the ordinary for a dynojet.

How many miles total do you have on your car? Your question about the ECU and milage seems valid.

Numbers will always vary -- only way to know for sure what you gained is to compare to a baseline for your car on the same dyno, ideally under the same or similar conditions.

That said, my guess is that the gains, untuned, are about right.

And guys, this is FLORIDA in the SUMMER. That means high heat and high humidity. Both mean less air mass and less power. SAE corrections only do so much to compensate for that...

Next step is to see about getting a tune, which should definitely net you more power :tup:

But you have different parts on your car.. Not all products produce the same power..

zing!

What's important when you dyno is the different numbers you get from OEM to whatever mods you have installed. Every dyno... every car... will be different, and you cannot say "A Z should get these numbers on X brand dyno". It just doesn't work that way. Far too many variables.

It's all about the difference of hp/tq from OEM to aftermarket.

Thanks! I only have 5600+ miles for one year. I barely drive this car. I only drive her around town and to work.

:iagree: I only spend $1600 bux for this 3 combo. I couldn't be happier :)

Yup, as of now; from their list (proven power) I am still the highest hp 370z dynoed from them. Some got like 270a to 280 horses but I don't know what their mods are. I might get a tune soon. Thanks

I dynoed 286 on their dyno with ERZ HFC's

Not to be a buzzkill but it looks like the real hp number is probably 284-285 like the two other pulls without that little false blip at the end.

I understand that, however the word is that the Injen intakes, and ERZ HFC's produce very similar results. Maybe the Invidia Gemini is a bit more restrictive?

Wow, yours was impressive. So mine 290whp then is low for the three combos if you got 286whp for just ERZ HFC.

Well, I think their dyno might be a tad low plus like someone else said...it is rediculously hot and humid here in FL so we both might have put up slightly better numbers in less humidity.

Looks like you have a nice setup...I'd like check your car out sometime

That seems low. I think you should of done a Baseline Dyno. Always do that people.

My baseline was around 290 on a DynoJet stock!

I guess so too men. Yah, they had a 2nd meet last time at Tampa Int'l Mall but I didn't have a chance to go there because I am scheduled to work.


Imma gonna' try it again on winter for better temperature and humidity just like where you live lol.

I did a same day baseline on this dyno. Mine was 275hp which shows how the location and dyno calibration have alot to do with the numbers. The gains are what is important though. In my case, I gained about 12hp and tq across the powerband with the HFC's and they brought my AF to where it should be, so I was happy

Does the VDC should be turned off before the dyno?

That's also uncorrected, which tends to read higher...

What were the ambient temps/humidity that day?

But yeah, before anyone makes any modifcations, you really need to get a baseline and then make sure to go back to the same dyno for subsequent runs.

That shouldn't matter, but it's easily tested. I'll have to keep that in mind whenever I get around to dynoing.

I've seen gains of over 10% dynoing when it's 45*F instead of 95*F. On a 275+ whp car that's nearly 30 whp.

Summertime blues :icon17:

oh well, my bad I didn't have a baseline dyno to compare with. :shakes head:

Eh, no biggie. Use this as the baseline for subsequent mods such as tuning :tup:
