jeff: lets see some pics of the car with the intercooler and stuff... love the HRE's

Did your installer reprogram/tune the uni-chip for 93@9psi via unichip/APS software and a laptop while on the Dynopac or did you use a pre set MAP for 93 from APS untuned?

Tuning is one thing...but I just want to see one...just ONE dynojet dynochart. I am not trying to be critical, becuase everyone know I think the APS kit is a wonderful product.

Rotating a known mass (Dynojet Drum), will typically yield more consistent and predicable results...especially for comparison purposes between different cars and dynos. Not perfect...but closer.

Plus, since we have a whole slew of dynojet charts on this website, I'd just like to see a comparison of an APS kit on a DynoJet.

 

Phunk I'm not a huge wrap for Dynapack dynos though they do have 2 distinct advantages over normal load base dynos,

1) No tire noise and this is very useful when tuning/mapping engines as you can hear the engine clearly without tire noise

2) NO tyre slip when you're dyno tuning monster twin turbo engines or big grunter V8 / V10 engines.

On the dyno jet (and I don't mean any disrespect to you) I reckon Dyno jet dynos are very limited as you can't map engines on an inertia dyno with any degree accuracy as it's impossible to hold engine load..............period.

By all means take this to a seperate thread if you wish to discuss in more detail.

Thanks

If you're suggesting that a dyno jet is more accurate or a more repeatable measuring device than say a Dyno Dynamics, or dynapack, DTS dyno, or mustang dyno then I must say I disagree with your comments.

Accurate dyno figures rely more on the operator these days than the dyno brand itself.

Just another point to consider when measuring power on chassis dynos, it's equally important to have a set of controlled wheels and tyres where as the weight, rolling diameter of the tire is constant, and the tire pressures are set to a predetermined pressure, otherwise the power figures will vary all over the place.

That said if you utilise one dyno with and one set of controlled wheel/tire combination and in the identical environmental conditions now you have a level playing field and meaningful data.

I'm not wanting to start a dyno debate about which brand dyno is better than the other, rather help you guys understand that there are many factors that influence power figures and repeatability..............I've learnt this over a 30 year period of owing and operating chassis dynos.

Thanks

Well, you started the debate...so let the friendly debate continue!

Operator influence is MUCH more pronounced with the dynopack or any eddie current dyno.

On a dynojet, you are rotating a known mass...which doesn change...and nobody can change it. The only "correction factors" that can be manipulated are the atmospheric variables such as air temp, baro, etc. There is no "calibration" per se, with a dynojet.

Of course wheel size, weight, air pressure, and other varaibles will influence the numbers. As a I mentioned, it just allows for a closer comparison...but no dyno is 100% repeatable for the above mentioned reasons.

My main argument is that we cannot compare dynojet to dynopack numbers. And since more people on this board, and in this country, are using dynojet, I hope to someday see a dynojet dyno of the APS kit.

 

Ok my point is that the dyno jet is worthless from a tuning viewpoint (can't hold engine load) though no doubt the dyno jet is a good measuring tool and should be very repeatable.

There is also no calibration on a dyno dynamics load based dyno as the acceleration rate (ramp rate and inertia values are fixed) so that the dyno opertor can't fudge these values which ultimately impact on power readings.

To suggest that a dyno jet is more accurate or more repeatable than a Dyno dynamics dyno is clearly wrong imho as the important values are locked to a known set of parameters.

Bottom line I don't have any problem with dyno jet power figures though our dealers are into REAL tuning/mapping therefore don't utilise dyno jet dynos.

Hope to see some dyno jet power figures soon.

Thanks

Peter

 

2nd the question.. also was the install straight forward... seems like it was done with the engine in the car.. wondering if the mechanic faced any particular tough items to get done.. enjoy the power

 

Just communicated with one of our dealers in the US who has a Dyna pack dyno and at around 7 PSI boost pressure the APS TT system is producing around 405 to 410 WHP.


Notice Jeff got about 412HP (assume wheel as the torque graph states flywheel) at 9PSI wonder what the differences are in tune?

Cheers


Paul

 

Hey how about a vid of you running against a n/a Z? ;-)

 

Dear Masters
I try to Install the Boost Controler and Boost Gauge on my APS kit
any one can give me a where i can connect all the hoses
1> HKS EVC EZ II
2> Apexi EL Boost Gauge

 

I'll work on getting some pictures of the intercooler with the nose on. It's been raining for the past two days, but tomorrow should only be overcast.

I'll see what I can do about getting a Dynojet run posted. I do know a place that has one, but the my Z is about to take a long winter nap. I'm really wishing for some nice warm weather at this point. It's had to enjoy my new found power when my tires are like hard plastic instead of rubber.

Jeff

 

I can Imagine with the roads getting colder, it's hard keep the traction in dry weather... And I wanted more HP than you... I'm sure I would be happy with the numbers you have put down.

PS Did APS supply a 93 Map, or did XXtuning tune it for you on the dyno?

 

Okay, I want to correct a something I said earlier. I talked to the installer today and found that the dyno graphs I posted are with no tuning. They are straight out of the box numbers. I'm dropping the car off next weekend to have brakes and hopefully the APS exhaust (if we can get it out of cutoms, something to do with the paperwork) and some other stuff done and then the car will winter in XXTuning's new showroom. Hopefully I can get a Dynojet session in before I drop it off.

Now for more pics

FMIC with nose on for those that asked.

Air Guide not part of the kit

To answer some more questions, there were no particular problems with the installation, although XXTuning will probably pull the engine for future installs. The two toughest parts of the installation were tightening one of the nuts attaching the driver side turbine to the exhaust manifold (rear, next to the engine) and installing the fuel pump. since my car has a relatively low VIN (6421), it is noted in the installation instructions that the fuel pump supplied with the kit is a bit longer than stock.

The total time spent on the installation was in the neighborhood of 40 hours, which included installing a DefiLink Controller, some sensors, and a DefiLink Display, as well as welding in a bung on one of the cats for a wideband A/F sensor.

I hope this answers most of the questions I didn't get to earlier, and I will try to get some time scheduled on a dynojet to give everyone a basis for comparison.

 

Nice... Those are some very impressive numbers/ w/o tunning on the base map! I'm looking fwd to those dynojet number as well... I love the cooling plate that's a nice professional touch...

 

Hey Jeff congrats on the APS TT system install and I hope you get some good driving in real soon.

Sounds like you're really happy with the install work done by the guys at XX tuning and be sure to give us all a full report when the the APS TD exhaust is installed and the engine full tuned...............I reckon you'll easily go 450 WHP on good 93 octane fuel.

Thanks

Peter

 

From what I have read on this site I would not recommend this level of power on stock internals...


Paul

 

So true!

Awesome pics, looks like a great, clean install. Look forward to some dynojet numbers like everyone else is saying as well, and hopefully some vids of her in action before the first snowfall.

 

Thanks folks. I've scheduled a session on a Dynojet for Thursday late afternoon. I'll post the results Thursday evening or Friday.

Hey Peter, I'm definitely pleased with the install that XXTuning performed. They are a top notch shop. I'll report on the APS TD and Full Tune when they are accomplished, but the weather here in New England is getting a little cold. It's tough to really get a good impression when the ambient temp is in the low 30's F. I hope my cold tires will hook up with the rollers on the dynojet!!

This weekend my car will be going back to XXTuning for brakes, and some other work. I'll see if I can't get some video, but no promises there.

Jeff

That is very cool of you to go out of the way to post up dynojet numbers… I’m sure all the FI guys in this Forum appreciate it…
