Auto Std model
100% stock except for K&N panel filter at the time.
111.7kw (I think, the dyno chart is at work).
Performed on rolling Dyno Dynamics.
Jazz: stock, K&N panel filter.
120 Series Prado GXL Petrol: Pacemaker extractors, Dual 2 1/4" exhaust, 70 series MT STZ's, ARB non-winch bullbar, snorkel, Dimpled and slotted rotors.
Opps.. I just realised we need to put in power mods..
At that time of 126Kws, the following powermods were done...
K&N Typhoon CAI
DC Sports Headers
Custom Single Outlet MagnaFlow Race Series Zorst
Apexi VAFCii
Ok guys. As you know I have tried to do cost effective practical mods to improve the day to day drivability of my 05 Manual Euro. I think I have succeed to an extent. Its a lot smoother and more tractable through the gears and generally better behaved than stock. I was aiming for 160kw at the fly which is a modest 20kw up on stock. Not sure what thats at the wheels as it depends on the dyno on the day. I have been aiming for outright max power, but more pull through the range. I did dyno my car to do a baseline at a dyno near my house but it was ballsed up due to them leaving VSA on and me not warming it up. It was 86kw!!! ATW. Lol
Now to the results:
Power Mods:
Car: 2005 Euro 47000km Manual. Ive owned it since its birth. Intake: Comptech Icebox with K&N Filter Header: Topspeed Stainless Steel DC Sports copy. Cat: 300 Ceramic Cat Ecu: Jtune Mild Flash. Vtec at 5000rpm.
Dyno: Ultimate Tunes Philip ACT MAINLINE DYNO. For reference EUR003act got 133kwatw in his modded 03 Euro a month ago at the same dyno. I understand a few euros in the past have gotten around 102kwatw in the past but I cannot confirm this:
Results: Power: 118kw Torque:188Nm
Interpretation:
Fortunately for me we were able to look up Euroact13 dyno chart and set my dyno runs to the same parameters. I had a total of 7 runs. We also overlaid the two dyno runs and the results were very interesting. His dyno sheet is on this forum somewhere and I will look it up. Im sure he wont mind as it makes for an interesting comparison.
But basically my dyno is right in line with what Jtune have on their website. Its a similar power increase over stock and the shape of the graph is near identical to their graph. They claim about a 15kwatw increase with the reflash and I/H. I have I/H/Cat and Im getting about 15kw over stock if you make the assumption a stock euro is 102kw on this dyno.
That gives me approx a 160kw flywheel reading which is EXACTLY what I was after for the money I spent.( approx $2000 for all the power mods in total.)
So mission accomplished I guess.
Euroact13 car has a more power to start then I have a bit more through the midrange then his took off at 6000rpm to 133kw. Mine rises steadly and my Air/Fuel is very stable if you look at the graph. Euroact13 leans of between 6000rpm-7000rpm. This is probably where the extra power is from his RBC intake manifold, high quality toda header and a few minor mods like pulleys which I dont have. My power is pretty linear due to the Jtune flash and vtec 5000rpm engagement. This makes the car nice to drive as I have stated as you get a very progressive power application and a good meaty feel in the midrange and this graph supports this.
So its good for day to day driving as I hoped for. I was hoping for a few more KW but realistically it depends on the dyno and a few variables.
I am considering a few more mods but the bang for buck stuff is starting to dissapear. I do have a hondata heatshield gasket and I can do a throttlebody bypass but we are talking maybe 1-2kw here.
I would consider a RBC manifold but dont want to sacrifice the bottom end. Euroact13 car seems to be good in the low rpm even with the RBC. I might also consider an exhaust at some stage. I think the Topspeed header is letting me down a bit but it's alot better than stock though and the price was right.
Ill wait and see the results of Euroact13 with the new head and other goodies before I decide to quit modding or now. But its looking expensive from now on and lets be realistic, this is not the car for power mods at the end of the day.
For now I have a brilliant commuter car thats got that extra poke when i need it and is brilliant on fuel! Not to bad at all. I reckon the car is sub 7secs 0-100kph now but I cant prove it yet.( not that im aim for drag speed, just using it as an example, used to be about 7.7secs)
Euro engine gurus: How does this chart and A/F look to you and the other stock/modded euros? You reckon the Jtune has done much?
Looking forward to your intelligent and insightful comments as always.
i like your work, ill have my results tomorrow...
