380 Dyno Charts

[s_tim_ulate]

As requested: A Sticky for all your 380 dyno charts.

Please post your charts and a short description of your mods, the conditions when you dyno'd, fuel etc.

Don't spam this thread with discussion. If you want to discuss your dyno results please post in this thread

[Knotched]

Mod:
Sports exhaust - 2.5" system from headers with resonator and sports muffler only.

Fuel
98RON

Transmission:
5 speed Tiptronic

[Knotched]

MOD:
Chip Torque Exede Processor
90mm AIr Intake
K&N Filter
Sports exhaust 2.5" with Supacat striaght through muffler and third catalytic converter removed.

Fuel:

98 RON

Transmission:

5 speed Tiptronic







Notes: Intake temp was very high; colder intake should hit 200hp. Hi and LO values mean dual maps - Lo is for lower quality fuel or better fuel economy.

Special Thanks to Chip Torque; first 380 auto to be chipped in Australia.

Unichip Q installed.

Okay, I finally got mine dynoed. While not in the same league as Knotched and Foozrcool, I was pleased to see mine's made the same power as Knotched's first dyno run, despite having different mods.
What I have here is: Berklee straight thru rear muffler, US Galant 90mm intake, K&N filter, removed under-bonnet front rubber strip, removed plastic engine cover, and running 98 octane fuel.
So for people running these simple & affordable mods, this is roughly what you will recieve.



The video has been posted on YouTube also, and shows 139kW and 200+km/h. It is the ONLY video of a 380 having dyno power run.

Needless to say not happy.

This is with 90mm intake
K&N Panel Filter
2.5" exhaust with high flow muffler all stainless steel
Custom Extractors
Unichip Q fitted and (supposedly) tuned.

well tonight went to SKR and stuck my car on the rollers. i wanted a before reading before i start doing the engine mods.


average was 149kw atw. highest was 150.3kw atw. its a good starting point. got an intake restriction at the top end so will be looking at custom maf sensor and throttle body.


engine mods on this run were

2.5" exhaust from headers back into twin 2.5" at rear
galant 90mm intake
secondry intake (50mm)

Dyno was done at the Street Torque (3/10/09 no the date shown). 203fwhp for naturally aspirated V6 factory tune. Mods included exhaust and air-intake...oh and done on the 22's.

OK, finally had my ChipTorque Exede fitted & tuned by Steve Knight yesterday.

Before runs (with Exede fitted but with bypass plug inserted) showed between 160 and 163 kw atw. And very rich AFRs, which we expected.

About 21kw less than my earlier runs back in August 2009. All sorts of possible reasons for this difference, including larger wheels & tyres (245/35 19 v 235/45 18), slightly different weather conditions (but not much), incorrect parameters set by Steve last time (I think this is a strong possibility, note the big difference in SAE J607 correction parameters, from around 2.8 last time to 3.95 this time), and this time I noticed/heard a lot more slip on the rollers.

Steve reckoned that Mitsu motors have good days and bad days, and the day back in August 2009 must have been a good day and yesterday was a bad day!

I reckon the slip was a big factor, when I drove it off the rollers the front wheels were spinning on the concrete floor at 1200 rpm!

The after runs, once Steve had tuned the Exede, showed 168 - 170kw atw. So a reasonable increase in top end power.

I was hoping for an increase in torque in the mid-range, but this didn't happen, instead I got a reasonable increase in the top end, from about 4,000 rpm onwards.

The main change was in the AFRs, now tuned so that it runs between 12.5 and 13.4 instead of the horribly rich 9.6 to 11 that it was running.

I've noticed a significant increase in fuel economy already, from around 11.6 l/100k to around 10l/100k. Early days yet, but it's looking good.

It feels punchier in the mid to upper range, and happier to rev out to the rev limiter.

Other main change Steve made was to advance the timing a bit. The map already in the Exede was apparently tuned for 95RON and had 'only' 1.5 degrees advance, so Steve took it out to 4 degrees advance. I didn't check if he meant 4 degrees advance on the stock 6 degrees retard (ending up with 2 degrees retard), or a true 4 degrees advance. I think it was the latter.

Photos of the installed Exede and the dyno print outs below.

Note the nifty mounting bracket. A DIY job, $6 fencing bracket from Bunnings!



Different angle showing more detail of mounting bracket.



Check out the AFRs. Red line is stock ratios, very rich, blue line is tuned ratios.



Again check out the AFRs. Red line is 'base 380 map' Exede ratios, a bit too lean (over 15 in places), blue line is tuned ratios (same as previous chart).

Thought I'd post this up here too, as it's a 380 engine, so technically a 380 dyno result!


Car: KJ2 AWD
Mods: 6G75 swap, extractors, 200 cpi cat, 2.5" catback, plus straight through muffler
Dyno: SKR Mainline DynoLog Chassis Dyno with all runs in 3rd gear.
Power: 134.4 KW ATW @ 110KPH
Torque: 535.5 NM @ 84KPH



The lower figure was a 'base' tune with only AFR's corrected, before tidying it up & adding some spark.
