Topgunz - air to air upgrade

mikey1600 · 02-10-2017, 10:09 PM

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

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.

How much extra power would the Si trim upgrade net you?

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.

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.

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

nic370 · 02-04-2017, 12:37 AM

Mine has made 500 crank
It's been pulled back down to 475 as I was getting a bit of knock at the top
This is on the 7lb stillen pully
A2a 1000cc Injectors aeromotive 340 and cjm fuel return

If I can figure this knock it should fly over 500 but 420whp I'd plenty for now on UK roads trust me

Glad it's on the road again Optimizer. I bet it drives better with responsiveness also.

Yes and thanks TopZ.
I'm still getting used to it again, especially after it being off the the road for a few months. Yes it's very smooth and responsive and I think I can live with the Tial BPV noise. It's loud but not an "acute" type of noise. I'm getting new tires shortly which is really necessary with this power and a 4.08 diff. I'm going for Yokohama Advan AD08R's. The stock Potenza's aren't sticky enough.

TopgunZ · 02-04-2017, 07:35 PM

Glad to hear it. If you want to quiet down the Tial put a 1.5" hose on it and run it back into the engine bay. Adding a filter the end of that will quiet it down even further.

Here's what 18psi on air-to-air looks like at sea level

Saw that, I thought it was a different one that had a built engine not this one. A TT or something like that...

Yeah I talk with Phil quite often who built the car. I will be around the same psi with my build but will be on E. if I don't make 700 minimum I'll be upset. Lol

Daaam where is that car located? First time I've seen that thing...Those are very impressive numbers...I wonder how the piping is on that set up.
