Test pipes and invidia Gemini

Yeah, less restriction, lower psi, more power

What are you guys gapping the NGK GTR Plugs to. Or are you just running them as pre-gapped?

That's Very strange as to why I'm seing 10/11 psi then topz as we discussed on email I'm baffled by that one

Dyno results from Air to Air upgrade!!!
 

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.

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.

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 :)

Sorry I don't speak gloabalism. What is this in Freedom? too lazy to convert.:icon18:

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

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. :driving:

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 :icon17:

That's got a few other bits aswell
Rods pistons etc
Saw it on facebook the other day
