Did he take the intercooler out of the manifold? If that is in there it will plug it up and make more backpressure/boost.

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! :driving:
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.

Hey mate, good to see a fellow Aussie doing it!

were you already custom tuned before installing the A2A? if so that's a pretty damn good increase to be honest.

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

Si adds about 2-3psi, in theory should be extra 40-60whp. That's not contemplating the e85 don't know what that would add by itself.

Well since we now have a reasonable idea of 10 psi + A2A kit nets about 320rwkw, and there is a guy on the original 6 psi kit with e85 making a hair past 300rwkw... I'm going to stab for fun and say 12 psi + e85 + A2A + good tune will hit ~360rwkw (~480rwhp).

In a couple of weeks, I'll have my own results of 10 psi + A2A as well. :tup:

Do you think I will be able to hit 360 rwkw with the AAM TT Kit on 10psi? No e85

It won't get you 50whp. It flows 1150cfm vs 1050 so around 10% more. It will be closer to 2 psi which will be around 30-35whp.

Stillenz84 made 556whp with the above.
Frandy made 540whp with stillen fuel components, pump gas plus meth.
Sudip made 515whp. I just posted his dyno a few pages back. It's not hard to get past 500.
