Zex 75 shot. Video install to come.

Also my car made less HP with intakes on vs stock intakes with drop in K&Ns. Felt in the seat and seen on the dyno.

 

looks right on the spot. have fun!

 

So is that tuned for 11 afr?

 

Nice results, cant go wrong with the N2O... I am curious to know what intake you were using prior to the K&N drop in's that made you lose power.

 

Very nice. Are you running colder plugs / timing pulled?

 

1 step colder densos, no timing.

11.3:1 AFR is strictly from the fuel jetting on the nitrous, I love how flat AFRs stock 350z ecus have

lost power from the fujitas vs stock intakes with k and N drop ins

 

Yeah your air/ fuel looks prefect. Nice.

 

Congrats and no surprise there

 

Your nitrous AFR is dead on.

BTW, so you got 1 step colder plugs? What kind (copper, iridium, etc) and what model?

I'm a bit confused to see almost a 75 whp gain from a ZEX kit, though. I've always heard that ZEX (and Dynotune) rated their shots at crank, but yours is almost a 75 whp gain on a DJ. Perhaps, for the HR kit, their method of jet size calculation changed. What jet sizes are you running on each side of the plenum?

Also, try to give us a printout without any sort of smoothing factor on it next time, so we can see what it's actually doing on the dyno.

 

Nice numbers and looks like its running nicely.

 

the VQ37 Denso iridiums that I sourced the PN for a long time ago.

Zex did test this on an 07, hence the proper jet sizing and the custom machined fuel line adaptor that keeps you from cutting things in your fuel line. It picked up about 65 HP on avg, which is about 75 at the crank.

Smoothing just makes the graph easier to read, generally the variance isn't that much.

AFRs were a pretty flat 11.3:1, nice and safe.

I love having a 424x Dynojet right behind my office

 

what are your jet sizes?

 

Nice dyno! Get a tune and your intakes won't lose power but gain.

 

Looks good, expected more tq though...

 

more than 100 lb/ft on a 75 shot??

The intakes aren't going to make more power on a tune. The stock intake design is straight through, and the K&Ns made for a better filter.

30 on nitrous and 17 on fuel

 

waiting for VDO

 

How is the WOT switch that with the kit? Driving does it spray in first or can you set it to start spray in certain gears? Are you using a bottle warmer? I am looking at getting the kit so I'm just trying to find out everything about it.

 

All Zex NMU kits have the built in TPS calibration switch. It does not have a skip shift option, though their window switch does.

I have their cigarette lighter bottle warmer.

 

Oh by all means did not mean to down play your numbers, they're amazing actually. I looked at peak more so than gain.. That's my fault..
