We got to the Dyno yesterday and our best run was at 349RWHP. I will try and scan in results today and post. I will try and post an MPEG as well. The guys that did the Dyno also did a Stillen unit and that's on the print out as well. If I had a Stillen I'd be pissed.......

The car is INCREDIBLE. Ths sound is AWESOME...... I am extremely pleased with the install and the results in total. When Eric gears up his own shop, I would recommend him to anyone.

I still have a slight squeal at startup but goes away immediatley. I'm going to try and drive the squeal away.

 

Man, this thread is really making me want one of these ATI beauties. Wow!! So far, it seems like everyone who has installed this SC is happy.

Paolo - please keep us posted on your install. I'd be really interested to know what sort of numbers you are getting with your otherwise stock setup.

 

Max, a couple questions.

First, what was your quarter mile e/t bone stock?

I have an auto g35 sedan and know I am some amount slower but I haven't been to the track yet. I want to be able to run a 12.9 with the S/C.

I assume you have been to the track since your sig says best e/t of 12.7, is that with the Procharger?

 

That's great!! I can hardly wait to see it Friday. See ya' then. (now get those headers on there!!)

 

My Z is the 6MT stock prior to procharger. I hope to have it by this weekend. Probably dyno'd next Monday or Tuesday. I'll keep everyone posted.

Question: for those that have their cars back, once the FMU is set, how often do you have to mess with it ?

 

Max: so you're saying its NOT a DynoJet right? Is it a Clayton? You're talking about load bearing.. Claytons are more for tuning and real world applications ,but i think the standard for products is still the DynoJet brand. :P


Do you have a boost gauge installed? some gauges have a 1 psi loss internally.. my autometer guage would always read a little less than normal.


The Stock exhaust is pretty good. your bottle neck would be the headers/cats... imho if you're serious about big HP, with a blower go either 2.75" diameter or 3"



what ECU management does the ATI kit come with?
Technos was supposed to get a customer w/ an ATI Z in later this month to tune... but i havent heard anything... even with a piggy back, the VTC change points,rev limiter and speed limiter would still be stock... if you remove the battery and plug it in and dyno pull. your numbers will always be a little higher, but then it would go back down.. i wonder if anyone else had successful programmed the ECU for positive boost mappings to overcome the MAF.... doo bee doo bee doo...

WRT
"what ECU management does the ATI kit come with?"
Most ATI purchasers could answer this but:

The ATI kit comes with "no- ECU" management.
It comes with an Aeromotive type FMU and Aux inline fuel pump.

So ATI doesn't touch the timing, rev limter etc.

Hence an opportunity for Technosquare and the like..

 

I talked to a dealer of the procharger, and I was wondering, what version are you guys buying??? There is a tuner and high output kit, and the high output kit is supposed to put out more power cause it comes with a high flow fuel pump. The performance difference is supposed to be 40% more power for the tuner kit and 60% for the HO kit.

 

How the fuel consumption changed after installing SC? I have 19.8mpg on a stock car now...

 

My Procharger has shipped

Tracking number says it should be here tomorrow........Thanks Mike and Spencer at Altered Atmosphere........Thanks ATI..........I'm calling Force Fed Performance today to talk about installing.......i heard Max's and it sounds like frickin' jet......can't wait for mine to sound like that too

 

little rod

Note: A larger fuel pump alone does not "create" an extra 20% power. A smaller pulley (ie. 9psi rather than 7psi) with adequaute fuel delivery to maintain optimal A/F ratio over the powerband will and adeuate octane to keep the factory ECU from "de-timing" does.

So if ATI offers a bigger aux pump it is in anticipation of increased fuel demands due to boost levels beyond the 7psi "base" kit.

A good question for ATI and tuners is, how much headroom does the default 7psi with FMU+pump provide? Is it enough for 9, 10, 11.. psi on the VQ setup (assumeing factory ECU settings and injectors.

Personally the default kit's Aeromotive FMU , though simple is kind of "neaderthal" by todays aftermarket FMU/piggyback ECU standards. Big fuel, red box,***** good ,ugg.

I would prefer to see a PC downloadable (two map switching min) piggy-back ECU with inline pump / aux injector control capablites. Timing maps can be controlled from the piggy-back unit.

Then all a factory ECU re-flash is need for (on 6MT) is to :
a) remove the speed and rev limiters
b) disable the "background factory learning algorithm".
c) maybe a doo-dad here and there (like support for a ~160 thermostat and early fan engagment.

For the 5AT guys , ECU changes are more invoved (shift point etc).

 

Call FFP immediately and make an appointment to beat that other guy who ordered one! By then they will have the plugs too and I will be out there next week.

Cheston,

The Dyno is not a Walton I don't think it said Dyno Performance on it. On the software part, not hardware it gives you boost, A/F, rpm readings etc it has a digital LED that gives you RPM's, A/F pretty much everything that is why it is 15k.

As for ECU's let me give you an example of how they would come into play.

Let's say I am on the Dyno at 4th gear and at 5500 rpm's. With this blower I am in excess of 130mph+ so at 5th gear at 6600rpm's I would actually hit the SPEED LIMITER well before I hit the REV limiter. That's how much damn power these SC's make.

So in 3rd gear if the rev limter was 6900 I would be at an estimated 120mph! In essense I could do a 1/4 mile in 3rd gear lol. W/O being able to play with the rev and speed limiters I have too much power now. And that is at 6.2 boost and the Dyno measures the boost to the tenth.

N20 will give me more torque and cool things even further I am glad someone finnaly admitted that the catback and headers help not hurt this application, I was having a hard time explaining why the Dyno ends so abrubtly it's because we are going too fast at that point. If I were on a highway and not a Dyno and I did 150mph I guarantee the psi would keep climbing ! On a dyno that speed is unsafe and if you are bone stock intake and exhaust you are gonna get higher exhuast readings which of course will give you different A/F numbers for the FMU. That is why I say each car will vary. You must be under 800 degrees!

With the numbers I posted earlier from someone on the East Coast with 93 octane and stock exhaust manifold but a different muffler they made 360+RWHP. No Crawford Plenum same Dyno I guess Paul is going to and it was a 6MT too!

Spencer can elaborate on that at any time. We don't have 93 octane here just 91. I can get 100 at the track but I am not convinced it doesn't through the timing out of whack yet.

Anywayz I am meeting Jrit's friend and John350Z in a couple minutes to show them my install.

EJ call me tonight.

Oh plugs, go copper not platinum and NGK they are special order.
FFP will be stocking them though.

Oh yeah again SC squeel.

I heard it will get better after your first oil change to the SC at 500 miles. You should have got 4 bottles of green oil and been told to change it after 500 miles right?

Just remember that w/o a wideband 02 and EGT you are not going to be properly tuned and ATI's numbers for the FMU are not written in stone for modded cars (A5T's especially.)

I believe I am the only Auto with an A5T and 12.9 is not a problem at all I am looking at DEEP 12'S

My stock N/A was 14.0 and 13.9 with tires and after the plenum it was 13.6 the 12.7 is N20 I haven't done any SC runs but it you can do the math it will be better than 12.7 with ET Streets and a shot of N20.

Use an ET Calculator.

 

I would have thought that rpm and speed are directly related and that hp plays no part in that equation. I mean, given "x" rpm and "y" gear ratio, they should produce "z" speed, regardless of how many hp the engine has. Hp of course will increase the rate at which you achieve that speed, but that's all, right?

I am a little woozy right now, so my physics may be incorrect. Please feel free to comment on my possibly incorrect supposition.

 

First off congrats to you guys on you hp gains with the SC. I don't like you guys right now.

This is just the beginning. Wait till the turbochargers come out as well. In another 12 months there are going to be some sick Z's out there (SC'd and Turbocharged).

One request, if at all possible, when you guys get some track numbers, can you please post them in a seprate thread in the Racing section so we don't accidently miss the post in this huge thread?


Also, wait until the temps outside drop and the air entering the engine is a lot denser, the beauty of FI!

And my last comment. You guys have a $30k+ car, expensive wheels, go fast parts, but no DIGITAL CAMERA!!!!!! Come guys, lets see some MPEGS....please!

 

http://www.rpmoutlet.com/ati350z.htm also want to make sure it comes with everything that other vendors are selling for 5k.

 

MaxHax.

You mentioned the that the abrupt drop off was due to either bounging off the speed limiter, it seems. And that if the speed limter were removed (quite possible as shwon already by Technosquare) that it woudl be tought to run full out with N2O etc due to unsafe speeds on the dyno.

Well having the best Peak HP and TQ numbers are good for first impressions , but after that, it seems like what is most important is "relative" gains with each "power mod".

So assumeing that drivetrain power loss is relatively constant , and that lower gears (ie below 1:1 final drive) should yield "more" DT loss....You should be able to re-run the exact same setup but in a l"ower" gear , ie 3rd or 2nd and use that by which to extrapolate you future (higher output) runs. Just add the measure loss delata back to show the equivalent 1:1 output.

So from that time on you can run a lwoer gear and not bouce of the speed limiter. Then all you need is to open up the rev-limter to get the true max delta output.

Hope this makes sense , but it seems like form now on you really do not need to run dydnos in 4th gear and you don't need to run the car on the dyno at un-safe speeds.

------------------------

You are very intelligent. This is of course exactly what we did in 3rd. It was still 6.2 6.3 psi though.

In the end it's just a number right? Like I said the timing is crucial and I am comfortable that in all gears my A/F is perfect not to fat not too lean as this is a *semi* daily driver.

If you search every post I have made here since day one you will find I have always said that people but too much stock in Dyno numbers instead of the tuning aspect of it so I digress.

What it does on the track remains to be seen I have seen RWHP of 325 beat 400 RWHP cars the Dyno is just a tuning machine it doesn't race the car for you, that's my part of the fun and yes it will be in the race section and there is a competition going there so I am not revealing everything other than this (ANTI ZEX PLUG INSERT HERE!) my new addition recieved today!

 

man you mean serious business!

 

I'm just having fun, seriuos is Paulo and his 8.5 compression setup and 15-18 lb pulley! He is at Mikes at Altered Atmosphere bone stock right? I'm awaiting his results to see if boost goes up on a stock car.

I wonder what his will do bone stock and then with all the mods he has planned? Is Mike doing all those mods too Paulo?

That's ZEXY!

8.5 compression and a 15 pound pulley and N20 with stock exhaust!

I would lable that as "seriuos."

 

MaxHax

When you ran the 3rd gear dyno, were you able to hit RPM limiter?

If so, was HP still climbing or had it already gone flat?
