I'm looking to do the same except adding E85 + Si trim upgrade on the charger

Yes I was previously on a "safe" and conservative Uprev tune with the stock Stillen setup.

I was unaware Aussie dynos read low. Sounds like you are all getting mustang dyno numbers. With that, would a mustang dyno show another 15% drop there?

Easiest way to figure out the recalc is to take your stock car that we know is 332bhp. What does a fully stock vq37vhr make there?

Here are all my Dyno results from stock to A to A, using same shop, tuner and dyno and all done in the warmer months here on 98RON fuel.

On this dyno my stock Z was making 316WHP, so based on a 15% drive train loss (MT), this would be 363BHP, not 332BHP, (Nissan 370Z stock), and our Zed's are quoted by Nissan as the same BHP here as in the US at 332BHP.
Mine now makes/measures 449WHP, a 133WHP gain, using this calculator:

Horsepower to Kilowatt (hp to kW) and kW to hp (Kilowatts to Metric Horse powers) Online Conversion Calculator - Converter / Chart / Table

Does this mean I'm therefore making less than 450WHP in reality?

I'm curious about this too. If the Dyno readings were similar is the US to AUS, shouldn't I be closer to 500WHP with my A to A setup? If not what is holding me back from being closer to 500WHP as I thought my setup now is very similar to some of the US ones that are making around 500WHP? Mine showing about 450WHP on a "Dynapack" dyno.

A member on Zclub.com.au told me that in Australia our Motor Ocatane (MO) rating is much lower than the MO in the states, ontop of that our weather and other factors is why the Aussies cannot reach the same numbers as the guys in the states.

Well if you are running our equivalent of 87 octane then lower numbers will definitely ocurre.

Just ask the tuners how much timing is in it. I was at 25* on E. Which would be like 10 or lower on Crap gas which would leave a TON of power on the table.

MoulaZ · 02-12-2017, 12:42 PM

Definitely not an octane issue. We use the RON metric, where our 98 is equivalent to the 93 in the AKI metric used in the US. 2 seconds googling that gives you the information.

On the subject of timing though. When mine did make that initial 265rwkw (355rwhp), tuner said he had a very hard time going past 13* before it would start pinging horribly, I attribute it to being a very hot day (something like 37c/98f at the back of the shop), and the W2A being badly heatsoaked at the end of some 20+ dyno runs and the tuner refusing to listen to me to let it cool down. Very interesting you were at 25* with E85... how much are you on 93?

My w2a set up didn't drop below 40 degrees c here in uk no matter how cold it was

Now with a2a my Temps are sat at around 7 degrees c above abient it's amazing
I can get out after a hard drive and stick my hand on the charge pipe and manifold and they are cold
It is like 3 degrees here at the moment but still super impressed

I finally got mine tuned. I will add the Dyno sheet and video of a pull.

Its a 2016 370z Nismo with the Stillen SC, Topgunz A2A kit and 9psi Stillen pulley.

Only other mod done was Motordyne test pipes.

Problem I had was I was running out on injector at I think he said 7k rpm.
So will be replacing them real soon.

Nice man. It sounds really good!! Should hit over 475whp easily after the injector upgrade. Next step is get the Si trim and make over 500 if you want.

I was using the injectors that came will the Stillen kit, They are 600cc.
They hit 118 duty cycle at 7k rpm.

Rest of the exhaust is stock?

Ahh ****. Are you on E85?

I just ordered my AAM TT kit with 600cc injectors. Will I also max out injectors if I am aiming at 450whp?

You'll get a little more since you don't have to spend some on the SC. I maxed my 600cc injectors at 538whp and my tuner backed me down to 520whp.
