600+ Rear Wheel SOHO A2A 370Z On Pump!
 

Supercharger setups have come a long way for this platform over the years and we wanted to share this specific vehicles performance with you guys.

Anthony purchased our complete A2A supercharger system and performed the install at his house. Once completed he contacted us to have the vehicle tuned via Uprev.

The complete air to air kit that we offer comes with the following:
- Vortech Si Supercharger
- Stillen Intake Manifold
- SOHO A2A Intercooler & Piping
- Injector Dynamics 1050cc Injectors
- Aeromotive 340 lph fuel pump
- Turbogaurd or K&N Filter

With the install complete it was time to hit the dyno:

Additional Modifications Included:
- Custom Y Pipe and midpipe
- AAM shortails
- Test Pipes
- 9 psi pulley

On 13 psi and on pump 93 octane we achieved the following numbers:

Awsome
Dose this have a frs ?

SuperCharger setups have came a long way from the basic Stillen kit.

You brought the engine up to 7900?

Never seen a silver 9psi pulley before.

We did and I fat fingererd the pulley size, it is an 8 psi pulley, good catch :)

It does not have a frs

Huh. Interesting. Honest mistake I'm sure.

That's interesting
Everyone here in uk states you must have it

But my tunner told me the boost I was running the frs was just not needed
He is a very well respected tunner as well

Thanks for reply

Very nice and congratulations on the results. Is this also the map he will be driving on the streets - or was this more a dyno run to show what the system is capable of?

lol I copied it from facebook so in theory it was fatfingered once ;)

I wonder what it would look like if you put a filter on it. Some people like Dyno numbers, others prefer safety.

Yeah. They don’t publish or test that case. I already asked awhile back.

My custom designed intake with filter outflows a turbo guard. I’m hitting about 15 psi at only 6600 RPM.

Can you post up your dyno logs with the turbo guard and your custom intake. I'd like to check out the comparisons.

Ya what he said.

There’s already a thread dedicated to intake options. Check it out.

Here is an auto that has a filter on pump gas using the same setup, with two different maps. One for daily and the longevity of the stock automatic transmission and one for a more aggressive map.

Still the same fuel, just timing was removed :tiphat:

Please see above

LOL, come on. You expect us to believe that with nothing to back it up.

Hence my post asking to see his dyno logs. :tup:

Check the air to air intake options thread guys. Good lord. I’m not gonna post everything in three different threads. Eugene is the tuner, he’s seen my logs too. The boost logs are posted. We haven’t even begun to tune wot yet and there may or may not ever be a dyno. We’re doing remote tuning obviously, and that usually doesn’t include any dyno runs. But yeah, check the thread. Last time I’ll mention it. :)

I know. Unbelievable right? I’m very happy with it so far, but I still have more design and work to do.

To be fair it may be reading a bit more boost just like mine is. My omni 4 bar map sensor logs didn't quite match up with the dyno's boost reference. Dyno showed peak boost at 10.5-11psi yet map sensor swears it's closer to 13psi.

Yea agreed. Similar thing happened to mine. MAP reading was 14ish but gauge shows only 13ish. :driving:

I have 2 MAP sensors, and they both read the same thing.

For the rest of you, not you DrBacon:

Lets take a look at what Topgunz, Aaron himself, said about a design that was smaller in area than my design, and had a smaller air filter. The same design some of you on here not believing me actually liked! :) Turtle64b's design.

Turtleb64's quote: "Topz says that I should be getting 15-16 psi with my setup (he's seen more results from his kit than I have, so I trust him on this)."

Did you read that?

So I create an even larger opening, use ALL of that area, slap on a huge air filter and 6" velocity stack, and report 14.1-14.6 initially, look at and post the logs of 14.9, and everyone just shakes their head in disbelief. :ugh2:

So who is it really that you don't believe guys? Aaron? who looked at pictures of a more restrictive design and said thats good for 15-16 psi?

Or me? who opened up things even further, put a HUGE air filter on the end, and then posted the ECUTEK logs? Eugene also said I'm flowing so much, that my fuel setup with 485 pump, S1.SE FRS, and 1050x injectors is at 80% duty cycle with no room for E85. So even if my 2 MAP sensors are reading incorrect, my injectors are maxed trying to keep the A:F ratio on target. I'm *NOT* running rich at 80% duty.

:yum:

Sorry Nik, I've tried hard to get folks on the correct thread.

We all know the struggle to squeeze boost out of these setups if you want a properly filtered setup. Yet we all see 10 to 11 psi on ours with the K&N filter with a pulley that pulls 2psi more than this car above with just an 8psi pulley but it is hitting 11.6psi. So if you put the 9psi pulley on you should see 13.6 psi with the K&N!

Anyone have an idea how this phenomenon is occurring here only?

So my original setup with filter made 12.76 psi with one map sensor and .86 bar on my 2nd map sensor. Essentially the same. I had mentioned this to you in another thread and asked about your thoughts on it. Eugene said it might be the cam timing. But in working with the filter later, I realized the small K&N has a larger flange opening than the SC and so comes with a silicone piece to fill the gap. At the time I thought maybe the installer did that, so I left it off and put the small filter on again. For maybe other reasons, like the filter had become a bit crushed, I was making now only 10 psi. Is it possible that gap piece wasn’t completely closed at the end and let more air in than normal? And if so, is it possible others are doing similar, and not getting a really tight seal at the filter? Just my thoughts. This may be complete non-sense as I had a coolant leak and so had to remove all the piping and put it back. I had some slight boost leaks after all that which may have contributed to the only 10 psi after.

You right brah. When my car was finally running correctly for the first time thanks to Adel, he was able to pull ~13.3 psi on the vehicle. And that's with 91 octane, brand new coned K&N air filter, 9 psi pulley, 3.0" SC direct pulley and 3.2" jackshaft SC pulley.

I don't inow where everybody is coming up with these boost numbers. When my car had the stock K&N filter and the 9 lb pulley, it made a little less than 11 psi.

When I went to the 2.85 sc pulley with the K&N filter it made 12.88.

When I went with the 3.47 jackshaft and 3.00 sc pulley and turbo guard screen it made 16.4.

All confirmed on the dyno.

Making a little less than 11 is the norm with the 9 lb pulley and this kit on over a hundred kits. How 11.6 on the 8lb is happening is a mystery.

I would suspect it is because of where and how it is being measured.

What I mean by this is it depends where the map sensor or boost sensor is located. I read somewhere that the best place to pull boost pressure from is before the throttle bodies on the intake side. It is a more stable reading. If you pull it from the intake itself, it is not very stable. So, You guys are pulling the readings from two different places. That is why they are different.

Nobody is pulling it from pre throttle body. All of these are measured at the manifold. Including the one in question.

Maybe so, All I see is some folks in this thread making a bit of a mess.

Could it be from their set up having a bigger Y-Pipe and FMIC as opposed to your kit Topz? I don't know for sure, but was told that they run a bigger FMIC and that their Y-pipe is a full 3"

LOL, you’re including your self especially, right? With statements like

“So, You guys are pulling the readings from two different places. That is why they are different.” When literally no one is doing that.

I believe the maf pipes on both topgunz's and soho's are 2.75 inches.

Is this enough for you? I was just trying to be helpful that some folks may have taking the measurements from different places. But you however, it seams has a bone to pick.

Nah man, I’m cool! But if you’re gonna laugh and make incorrect statements about people here and incorrect statements of your own, and then of all things, accuse everyone else of “making a mess” expect to get called on it.

no offense to anyone but you guys should move this to another thread maybe?
