Champion mate! thanks so much!! I've already done the upgrade on my blower with vortech and the upgraded bearings etc.. so looking at the next step ;) already got the 9psi pulley from stillen originally as well. I'll order the other 2 and go from there.

Only other thing! With that combo is there a new belt I will need we can buy off the shelf?

No new belt required. The 3.47" pulley takes up the slack from going to the smaller 3.00" supercharger pulley.

wicked mate thanks! will order :D

Hey guys, can't find any good ecutek tuners in my area so having to stick with UpRev, will I need the UpRev GT MAf's?? - UpRev MAF GT

Have Seb remote tune it.

Yes. Look to sebs at SpecialtyZ. His remote tune will be better than any uprev dyno tune there.

To Poster,
If you do decide uprev, make the trip to GA and go to Jon at Z1.

I'm in Australia ;)

Build is still ongoing had issues with this level 2 limp mode crap, looking down to the flywheel, it was a prototype for a company here, they are sorting it out but this is taking a long time all up :O just wanna drive the thing!

I'm trying to do as much research as possible before I get to this installation, so I can avoid any potential errors, etc. I seem to be having difficulty linking videos on this forum, but I found one on YouTube that has me scratching my head. The title is, "Supercharged 370z e85 Ecutek Air to Air FMIC dyno run 460whp."

It seems like this guy has done everything right...A2A, CJM with return rails, tune by Seb, in ADDITION to e85. Why is he only making 460hp? What could he have done differently to bring it over 500 -- even to 550?

I don't plan on pushing the kit to obscene numbers, but I'm hoping to learn something here so I can at least avoid problems, and optimize my installation.

Thanks!

If you look in his video description he states that he is still running stock boost levels (stock impeller/pulleys).

I thought I was under the impression that 8-9psi would produce 500+, at the very least 480-ish? Maybe I misunderstood...

post link?

Ambient temperature, pressure, and type of dyno will have a pretty big effect on the numbers.

There's too many factors honestly. The dyno calibration/altitude/weather play big roles. He also doesn't state what % ethanol this run is at as well. Conservative tune?

Okay so let's take a look at this.
He has:
[x] CJM return rail system
[x] Tune by Seb
[x] E85
[x] A2A kit

He is still missing, as others have already said:
[ ] Triple pulley swap for faster spins on the blower head unit
[ ] Super Vortech Upgrade from 928 motorsports for both bearings and impeller
[ ] Exhaust system upgrades? Any headers? 3'' Downpipes?
[ ] Flex Plate Upgrade?

These things would help increase the power as well to the wheels :D

the description says he was tuned at 'The Boost Creep' which is in Longmont, CO at an elevation of 5000'. Solved.

Ouch.

I have the Si supercharger (not the Sci), a2a, 9lb pulley, cjm s1.se, tuned by Seb on flex fuel. My car made 541 @10psi on e85.

dayum!

also. @Redondo:
Do you also have 1050x++ injectors?
And what is the difference between SC and SCi head units if I can ask? :o

Yep, 1050x injectors. The Sci has a lower cfm rating. The new kit that Topgunz will be selling comes with the Si supercharger. When I bought mine from Stillen I paid a little extra for the Si unit.

Darn, if I knew that I would have done the same as you and pay a bit more for the Si unit :(

Seeing as I purchased the A2A kit which works with the SCi trim I have, I'm pretty stuck with the SCi trim so I will most likely send it to 928 sometime next year or toward the end of this year, to get the super vortech upgrade.

Live and learn :D

625 - 650 whp should be plenty enough before I crave more power after that anyway xD

The super vortech mod is a better set up than the Si trim, you can push the sc further with that upgrade.

You guys are so smart! :tiphat: I'm so glad I found this board!

P.S. Glad I'm at sea level!

Well yeah but that would mean if the super vortech upgrade was applied to both the Si and SCi trim, the Si would still win out no?

I believe the Si trim is basically an impeller upgrade to the Sci (I could be wrong) and you would obviously be changing that out with the super vortech upgrade.

Does it also include the ceramic bearings upgrade as well or just impeller if true at all?

No, it definitely doesn't include the ceramic bearings.

Oh, haha ok thank you for the information!

When I change out my supercharger pulley to either the 2.85 or 3.00", I'm going to keep the stock bearings, we'll see how long they last. :rofl2:

You already have 9psi pulley on serp side and a 3.47 pulley yeah?
If so, all you need is the 3 inch one since the 2.85 will overspin it xD

I replaced the stock 8psi pulley with the 9psi on the serpentine side. I haven't replaced any others.

Technically just the 9psi pulley alone slightly overspins the head unit unless you upgrade bearings.

Gotcha. Didn't know that.
Ugh. Gotta wait til next year before I upgrade that :D

MAF Issue
 

Would you guys mind sending me some of your data snippets that you send off to be used for tuning? I have an anomaly where one MAF (bank 1) is reading almost a volt lower than the other at times and I wanted to see if anyone else's car was doing the same. Thanks!

I'm at turtle64b@aol.com

EDIT: To follow up on this, it seems that there is not equal flow through the intake Y-pipe.

Swapping MAFs gave the same anomaly on bank 1, swapping the connection moved the anomaly to bank 2, and swapping the MAF while still connected to the same harness also moved the anomaly to the other bank. This means that at idle and light-medium acceleration, air flow through the two branches of intake Y, in my case, are significantly different. Since the Y pipe meets again in the manifold and the air mixes, the bank associated with the MAF that has the anomaly is getting much more air than sensed by its associated MAF and the other bank is getting less. This would explain my lean condition as well as the sometimes very rich condition that happens at idle.

Is anyone else experiencing this? If you look at your datalogs, it looks like one MAF reading out much lower than the other one. This can be dangerous for the engine as one bank will run rich and the other bank will run lean, potentially dangerously.

Have you replaced the Stillen extension cables with the later version? The original cables are a known problem.

Yessir!

Quoting turtle's message so it doesn't get forgotten, but is anybody using the innovate ECB gauge complete kit? ECB-1 (BOOST) Ethanol Content & Air/Fuel Ratio Gauge It comes with gauge (fuel temp, boost, ethanol content, O2). Complete kit also comes with MAP sensor and ethanol sensor. Is this everything I need or do I assume I still need a Zeitronix ECA2 Ethanol analyzer?--and anything else I'm forgetting in regards to gauges and flex fuel needs (aside from actual fuel system). Any reviews or suggestions for my gauges?

I'm running the complete kit. I believe the only extra pieces I needed were the fittings for the flex fuel sensor.

I appreciate you! My post can fade in to the dark. I got a full speed density tune from Seb last night, flashed it this afternoon, and it's a night and day difference! Talking to him, some cars get equal flow and some don't. For those that don't have equal flow, some can be tuned for, and some can't haha. I plan to work with him on full SD unless I figure out some way to equalize flow. Thank you guys!

^^^ He'll for sure straiten things out he's a very good tuner
