Dyno results from Air to Air upgrade!!!

7 posts in this topic

Posted (edited) · Report post

Well finally after months of waiting for and stuffing around with parts from the US and lots of $$$ my shop has finally completed my A to A upgrade!  
Some things to note were that the Stillen fuel pump ran out of pressure when engine was at 5500RPM and was replaced with a 340LPH pump. I've ended up using a 3.00" improved traction SC pulley, stock jack shaft pulley and a 2.80"improved traction serp pulley, giving me 10PSI. I replaced both the SC and serp belts and used the extra idler pulley (with special spacer), that was supplied to me by the most helpful and friendly "TBatt". This is to try and stop any belt slippage on serp side. I am also using the Tial BPV.
The Stillen fuel injectors did not need replacing and I'm using BP "Ultimate" 98 RON fuel which is the best you can get here in Australia. The injectors didn't max out and are fine with my current tune. I'm also Uprev tuned and using the stock MAF's, so no SD tuning on this. The dyno is a "Dynapack chassis dyno which are popular in Japan. They are the "static" ones where your (driven) wheels are removed and connected to a unit that spins a hydraulic pump/motor. The wobbles on the dyno graph's lines are due to the Dynapack's sensor which fluctuates a bit in hotter weather (it's middle of summer here down under) and is therefore not at all to do with fluctuations with the engine, so ignore them. The tune is very stable and smooth and the engine idles perfectly.
Overall I was hoping to get a bit more power than this, but around 450 (safe) WHP and about 352 wheel torque, it's still great and I'm happy. I'm also glad it's all over and I have my car back finally! You can see the before (Standard Stillen setup) and after (TopGunz A to A upgrade) results on the dyno charts.

Did you use any fuel system upgrades, like CJM or Fast-500 in this build?

 

And how is the car going now? I know it hasn't been long, but do you have any initial issues once you left the shop or is it runnign super?

No special fuel systems, just the 340LPH new pump.

Car is running great and no issues so far. I can really notice the extra torque/power compared to the stock Stillen setup. 

I need much more traction now than ever before and have just ordered new Yokohama ADVAN-Neova-AD08's.

I've also ordered new suspension to replace my BC BR coilovers. I'm upgrading to MCA "Red's" Made right here in Oz and top quality stuff!

Sweet good to hear your Z is running well.

I can imagine how the power/TQ would feel.

 

I cannot wait till my AAM TT kit is here and I have had it installed and tuned. But I fear that will yet be months away till complete.

 

Patiently Waiting!! :)

      Hi Tony, just saw your post, although it is over 6 months old now. Did you end up getting your roof sorted? If so whereabouts. I own a Roadster, live in Newcastle and am having an issue with the deck lid hitting the roof 5th bow.Still opens and closes fine for now. It appears to be a very common problem as I have following the ongoing US 370z forum on this matter. There is actually a Nissan service bulletin out for this plus others for roof issues. Rodd

      I removed the stock cooler when I fitted a 34 row fast intentions oil cooler last year. According to fast intentions the stock water cooled oil cooler will hinder the effects of a front mount air cooled oil cooler. There’s a thread explaining why they say it’s best to remove the stock cooler  when fitting a front mount cooler if you feel like googling it.
