awsome stuff, yes a qaurter time would be cool to compare to jc's too


come on you know you wanna

Nice graph Matt!

I am taking the graph as showing power, torque, bost pressure and ? Or is it two runs at different boost pressures?

Anyway, power curve looks fantatstic - nice and linear delivery right from 3500rpm and that boost pressure is rock solid on 16psi - that Profec must be doing the job well!

Josh, did you go to 440cc Injectors?

Cheers,
Tricky

I went to 560cc's (they were a straight swap from an EVO that had upgraded)

Guys trust me the one thing I always wanted to try with this was the 1/4 mile, I am taking a week or two off in September so maybe we can organise something as it would be good to have company.

As for the graphs, it is a bit confusing but the red lines show the original setup the day it arrived and the blue is obviously the results of the tune so as you can see a huge improvement. Sorry Josh no AFR but Phil indicated a rock solid 14.3 off boost and 12.2 on...Tricky one sheet shows the boost and power (as you say rock solid on 16psi). The other is power and torque. N equals tractive effort which is not the same as Nm otherwise I could tow barges (3500 Nm anyone), my calculations show a figure of about 210Nm, alot of variables so it can be a bit tricky (geddit).

As for injectors, that is the one big unknown, the halfcut came with fuel and speed cut defenders wired into the loom so I have a feeling that maybe there were a few other trick features on it, especially as it was running 10:1 even back when I got 136Kw at 16psi, so I have no idea. But I ain't gonna touch them in case I jinx myself. As for the barrel yeah I think you should, that looked too small given the snail you are running...Just my 2c. Also Josh what's the deal with the injectors they seem huge, what other aparatus are you running in tandem I assume some large EFI pump, are you also running a RRFPR as mine has run rich as buggery for eternity, hence the reason I went the Adaptronic as nothing else seem to raise the AFR rather than in your case seeking to richen it up?

As for boost given the graph maybe I was deluding myself as that is pretty much what it was doing previously, whistling by 3K and all hell breaks loose by 4. So difference really, still hard to tell driving back as I had to be a good boy.

Yeah it sucked I missed the dyno day not because of this outcome but simply because I missed the previous one I went to because the car wasn't ready (JAFO) and this time because it wasn't ready. I'm cursed...Still bring on the drags.

Cheers

Matt

Yea when i bought the barrel it was (and still is) rated to 270HP so i thought i should be plenty - It'll cool up to about 14psi but i guess as i'm running a smaller turbo it's making a lot more heat on the higher boost. Your turbo is a fair bit bigger than mine.

Dean was running single 880cc injectors on his and was able to tune it down to 202HP ATW. I had 315cc in mine and they weren't enough so i would suspect you have something bigger as well knowing all the other stuff that came with it

There hasn't been any change in the drivability of the car down low with these injectors and the computer is having no trouble controlling them. I'm running at around 11:1 at the moment on full boost just to keep the inlet temps cooler, so once i change the cooler and get it tuned i should see some gains.

Your car was just running rich due to the factory computer which dumps fuel on higher boost levels, maybe it was coupled with bigger injectors and was just putting a lot more fuel in than it should/would have. Just putting the adaptronic on would have fixed this. I've always had a standalone and it was good up until i tried to get more power out of it and then it was leaning out on max injector duty. I'm using a Bosch 910 Fuel pump which flows 130L per hour and is rated at 380HP - it is coupled to a SARD RRFPR however it's not necessarily needed with the aftermarket computer.

Im sure we can manage to get a good turnout when you come up

Guys,

Just dissecting all this information........

I think the 560cc injectors are a bit big for our aplications, but this is just my opinion. Josh, I went for RC440cc injectors, as the computations said that these were optimum at 80% duty with a fair margin in reserve. Matt, I would suggest that no way are you running the standard 195cc units!

Josh, you are running a TD04L right. Much bigger, by about 25-30% in terms of compressor area than what Matt is running, a KKR280. I would suggest this is the 'secret' to Matt's fast and early spool times. (I love a power band that stretches for nearly 4000rpm. How flexible is that!)

Matt - love the torque curve, nice and flat and stable. Also, now that its up and running with nice AFR's throughout the rev range - DONT TOUCH A THING!!

Josh I am confused I thought you were running a TD04? The KKR 280 is a reasonably small turbo (GT25) size perhaps...?

As for the fuelling yeah Toyota's are notorious for running rich if you fiddle with them, I more meant that irrespective of what the standard ECU asks if the injectors are maxed out I wouldn't achieve 10:1 which reinforces as you say the installation of the Adaptronic. Yeah Josh getting it closer to 12:1 should give you gains for sure and a cooler charge from the large barrel will also help. Also I did a recalc on my Nm as I used the wrong figure off the dyno sheet, I believe it is around 260Nm which is a bit more like it...

Also when are the drags (I assume at WSID) run, Wednesday night??

UPDATE: Tricky you got in before me! Yeah I would have thought 560s to be a bit big, that is what I was getting at, there maybe something other issue with fuelling as 440s should do the job I would have thought, and yeah I am defying physics if they are 195s. And yes having had both along side physically the KKR is about 60% of the TDO4 I had.


Cheers

Matt

Yes 560cc's are quite big, but they haven't hurt the drivability of the car at all. From my calc's they are good for 448HP at the motor. So 360odd HP at the wheels.

Also looking at the horsepower listing on Austarlet there are quite a few guys running the same injectors as me:
http://www.austarletclub.com/forums/index.php?showtopic=7325

I have the motor i took out here ready for a rebuild with forged internals and bigger turbo but that is a while off yet. I went with these injectors because they will work fine and provide room for as much growth in engine development as i could want and also they were already there in the workshop and were a straight fit, so they fitted the bill nicely as well.

I think you'll find the KKR280 a bit bigger than my turbo, it really is quite small. When i picked up the TD04 it was just that a TDO4 and i had no idea what i was looking at, but after driving it and researching it further there are LOTS of different variants.

Just some that i have found here:
TDO4-9B-6CM2 265 CFM
TDO4-13G-5CM2 360 CFM
TDO4L-13G-6CM2 360 CFM
TDO4L-15C-8.5CM2 390 CFM

Lag is almost non-existent in my car, ask Dan when he drove it - it's boosting at seriously low rpm (under 3k) which leads me to believe i have one of the small variants than what might typically be found in some of the other TD04 setups. I have boosted it up to 23psi plenty of times now - if it was as big as it is meant to be then it would have made lots more power and probably blown the stock internals.

You guys got in while i was typing that, but here is a pic - both "TDO4's" Look at the size difference:

Oh and found these specs:

TD04-09B @ 15psi = 172Hp

TD04-18T @ 15psi = 305Hp

Sorry to take over your thread matt

Drags are every Wednesday as long as the weather is good.

Ahh no worries, yeah I just went by what the "typical" TD04 on a WRX is like, the one I had was huge...The forgie engine will be a banger...That is as far as I will be taking the development of the engine. Now onto suspension and handling. Josh do you have a dyno sheet of your last run as it would be good to compare curves, given as you say the KKR is by the looks of it a bigger turbo...

Josh has a little one

No good being big if you don't last long

Seriously, I drove Josh's car and there is no lag at all, the boost just seems to be there and the power delivery on the road is linear whereas my turbo does not kick in until 3000-3200rpm and when it does you know about it.

Matt, have a look at your injectors and see what colour they are, if they are grey they are standard injectors if they are red they are the 4agze injectors which are rated at around 380cc.
