You did say it would add torque. Which also means it would add power.

Oh I C. Sorry for the incomplete statement. What I meant to say is "it will increase low-end torque". I actually don't recommend doing so (putting a restrictive exhaust system back) at all for the sole purpose of increasing torque. As I mentioned previously, the increase in EGP and EGT will hinder the performance and cause potential damage to your engine especially for a car running with forced induction. From theory one will loose both "maximum" torque and power. Thanks for pointing it out. :)

It depends on how restrictive it is before any damage would occur. Turbos create a lot of backpressure and guys are running higher boost. Thats the nice thing about a SC over turbo, you dont have to worry about adding backpressure.

Its pretty simple really. The more air you can get in and out of the engine the more power you will make.

:iagree:

"Volumetric Efficiency"

You get me :happydance:

availability
 

Is this still available ? Same price?

Thank you

Yes, they are always available. Still $5650 through April.

Damn Aaron, at that price you can do the fuel system, install and tune for less than 10k.

One of the best things I like about SC is that it is predictable about when the power is available, simply look at your tach. Your tach is like a power meter. The more RPM, the more power. I love doing WOT 3rd gear pulls from about 20mph. It is like riding on a rocket that keeps going faster and faster.:driving:

:iagree::iagree:

And it’s daily driveable for a female spouse.. don’t have to worry about them overboosting and throwing a rod at lugging RPMs, or spinning out if they push down on the gas too hard..

I have an AWD Q60 3.7 w/7AT

I just want to do a basic A2A install, no intention to modify exhaust (if the cats blow I'll address it at that time), just looking for a bit more power.
I did consider just buying the Stillen kit as-is, but like everyone else here, the few issues with the Stillen kit bug me, and I don't want the A2W gear on my car. I like the simplicity of the A2A.

Couple quick questions:
1. Front bumper support, I see most people are using the F.I. support. Does that mean you remove the impact absorbing foam? I have also seen pics of cars with a cut-out OEM bumper support, can the TopGunz IC be cleared with a cut up OEM support? I'd like to keep the impact foam TBH.

2. I have UpRev for my other Nissan and it works well for that vehicle. I spoke with my UpRev guy and he said with an upgraded MAF he can tune the car just fine. Since I am going for a mild SC setup, what do you guys think?

3. For my basic setup, I just need the TG A2A kit and injectors and fuel pump, right?

Thanks guys!

I'm debating on saving for this but idk how what traction problems I'll have with a 4.08 final drive

Lots of other factors come into play.

Tire make/model?
LSD?
Suspension?
Driving experience?
2 Step launch control?
Weather?

I wouldnt let this be a deciding factor on if you are going boosted or not. Its not like you will just sit and spin. Your car will be a completely different animal with an incredible increase in acceleration no matter what components are on it.

Yes you can do things to get off the line faster in a dig but that is also 100% controllable by the driver weather you spin or not. Dumping the clutch and smashing the pedal will spin the tires even on a naturally aspirated car.

You still selling these?

Where can I purchase this?

PM him or his email: adidis@hotmail.com

I have been running this system for over 2 years on my daily driven Z. Love it ��

Hello guys. I am launching a website soon. Ill post the link when its ready. Stay tuned.

Good luck man!

What about Facebook, Instagram? That's where the copy-cat/overpriced companies get the uninformed to fork over $$$ for their stuff. :/

I know right!!

My problem is I don't do a very good job of marketing there. Who wants to help?

I can make it worth your while. :tiphat:

Here is the link to the site. Its will progressively get better but its a good start.

https://www.topgunspeedworks.com/

Glad to see you built the site to expedite the process! Your conversion kit is a must for those who have already owned the Stillen SC kit but end up wanting more power along with improved stability. :D

Nice website!

Glad to see you have made a success of this!

So now everytime we see someone on Facebook asking a $$$$ shop about “their” A2A kit, we just DM them this link. Https://topgunspeedworks.com/ ! Got it!

I have shared the link on FB to the AZVQ group.

Thanks guys. That was one of the reasons for needing to make it more accessible to others. These Knock off shops have the time and resources to pump it around social media where I was relying only on the forum.

Its sad that guys are having to pay hundreds of dollars more to get into a kit.

Please pass the website along as much as you can.

Aaron, the power and boost numbers of my dyno logs on your home page aren't correct. The red line is with the Turbo Guard screen and it made the 657 at 16.4 psi. The blue line is the NGR screen and it made 625 on 15.25 psi. Just an FYI.

Did you ever dyno on 93 with the turbo guard screen?

I'm in California, we of course don't have 93. But, I did dyno with the turbo guard installed on 91 but due to knock I had to limit my boost to 13 psi. I could have hit 13 psi with the stock filter on though so the turbo guard screen didn't make any difference on 91. On e85 I couldn't have gotten to 16.4 psi without the turbo guard screen. I run a wastegate so when I'm on 91 or want to run lower boost on e85 I turn the boost controller down or off and run on spring pressure.

TopgunZ, I saw your new website, it shows the FMIC and says "aftermarket tow bars easily fit" Is it possible to carve out the OEM bumper bar to clear the FMIC?

A friend of mine used spacers to maintain the clearance, which seems to be the cheapest way to solve it.

Better using more free flowing aftermarket exhaust. At least removing the stock cat.

Does anyone have a dyno comparing a stock or lightly modified car to one with this A2A kit?

What do you mean for "lightly modified car"?
Stock = no mods?

I imagine he might be thinking intake and exhaust.

My 2012 Sport 7AT with Typhoon intakes (bought the car with them), Z1 ported upper and lower intake, Z1 test pipes, and Borla catback made 316/268, dyno tuned on Uprev at/by Z1. I don't have my post-SC install numbers since I was T-boned before I could get on the dyno with a solid tune.

Yeah intake/exhaust and maybe a tune. I want to see how the power/tq curve compares across the rev range to get a sense of how my car would feel with this kit. For example, would the power in a lightly modified car like mine at 6k rpm feel like the A2A supercharged car at 3 or 4k rpm and so on?

The only way to get a "feel" of how the car would drive would be to drive one with the supercharger on it, built to the exact configuration that you plan to build yours to. Looking at a dyno printout and trying to imagine how it feels would be an exercise in futility. Not to mention, the way one car's dyno reads will, in most cases, be different to the next depending on: supporting mods, tuner, location/elevation/temperature, year of car, miles on engine, and almost any other variable you could think of. As they say: "No two cars are the same."

But, to get a sense of the power/torque curve, it's similar to stock in that it's linear except the #s are higher.

Here's a dyno sheet of my a2a upgrade if it helps you out. As North Style stated, it builds power linear but I can tell you it pulls like a freight train and feels nothing like a lightly modified car.
