Topgunz - air to air upgrade

Optimiser · 02-03-2017, 11:20 PM

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.

Definitely going to be hitting you up shortly when my A2A kit finally gets here.

Was so pissed when mine only ended up making 265rwkw @ 10 PSI & full MAF tuning.

Seb is eTuning mine with SD & MAF, and I'm very interested to see how that's going to differ to you.

Got a graph showing Boost or AFR?

Posted some of mine, and never sat well with me how leaned out my original local Tuner made mine. Take a look at the plug photo, Cylinder 1-5 were exaclty like that. Cylinder 6 was absolutely pitch black. Junked them and bought some HKS MH45L ones.

Yes it will be most interesting to compare your E "Seb" tune.

I only have the graph on the left to show boost and no AFR.

Sorry I don't speak gloabalism. What is this in Freedom? too lazy to convert.

Hah, if you're too lazy to convert then I guess it's always gonna be a mystery for you.

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

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.

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

Wrong thread. This thread is about Guns A2A kit.

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.

Makes sense. I was just using the typical average of 20 per psi
Obviously you have more specific information in this case. Good to know, helps me get an idea of what to expect on mine too

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