Xede Installed Today

[bcl]

XRDreaming,

That's a good result with just a XEDE install and tune.

You've increased max torque by around 25%, and the torque increase is spread across the whole rev range, so the car should feel much stronger.

Was any adjustment made to boost?

I'd recommend to anyone having these before and after dynos done to get 3 printouts:

1. power/torque

2. power/boost

3. power/afr

You'll then have more information to assess the changes.

For example, if you have a car that's running very rich, and maybe a bit down on power compared to standard, you'll probably see major changes to the air/fuel ratio.

If you been told it's just a tune, but you find boost has been increased, then the extra power may be mainly attributable to the extra boost.

Anyway, it looks like a very worthwhile result.

Well done Xrdreaming

Now for injectors and cooling of the air......

Scotty,

Has the current hot Brisbane temperatures affected power output significantly, or have you installed additional cooling?

slow driving under 50kph, bumper to bumper traffic & swelters of days all affect the cars performance. I raced a stocker before Xmas after driving at 40 kph for 5 minutes & we were equal. Drove for 1 minute at 100kph, raced again & I nailed him.

Thanks for the positive feedback guys, the car is booked in for next Monday to have injectors, intercooler spray and transmission oil cooler installed, I will keep you all posted.

Cheers,

Hi xrdreaming.

Mate instead of spending good money on water sprayers why don't you get a PWR intercooler, designed to bolt straight in 10mm thicker and twice the height, 1.5lb restriction instead of 4.5lb, only $895 and you don't have to stop at every tap you drive past. Why have a fire truck when you can have a race car?, especially considering that you are going to have an injector upgrade. Your standard intercooler will become your weak link

Also up in this kW bracket if you want to save your trans (if its auto) fill it with REDLINE, it will still run cooler without a trans cooler than normal ATF will run with a trans cooler. So if you have REDLINE ATF and a trans cooler you are going to run much less heat through the auto. Heat = destruction.

Regardless of which way you go once the bigger injectors are in you can run 10 -12lb of boost, man it feels good, enjoy

just seeing that people talking about waterspray stuff, I didn't expect to find many people talking about waterspray setups on here, being the wrx kid, I've toyed around plenty with watersprays, I've currently found the best value for money is the autospeed intelligent waterspray controller ($107) and then buying a sprayer and secondary pump from the washer bottle.

It is tuned by I/c temp & injector duty, so basically you accelorate and have a friend in the passenger seat set the position for the injector side, then heat the I/c up to a desired temp for the 2nd factor of the sprayer, now when both conditions are met which in reality is the only need for a waterspray (when you get up it while the cooler is hot) the sprayers will spray the core.

I tested this quite extensively against hobbs pressure switch (boost activated) and uni-chip/exede controlled sprayers... and I found if you want to save money and not fill up your waterbottle as much this is the BEST method.

alternatively you can set it to a very low temp and like 10% throttle duty and it'll spray just as much as any of these auto ones...

just my two cents.

p.s. congrats on those figures, I know guys with lil 4 bangers that spend 10's of thousands of $$$ to get the 200kw atw figure

go big sixes!

Cheers,

Matt

OK guys, had the injectors changed yesterday and water spray installed (Only temporary for a week or two while I scrape together the funds for the PWR cooler which I hope to have installed by the end of Jan. Also had a nice big auto trans cooler fitted and will be using redline fluid in the auto.

Result was I now have 238.9kw at the wheels (For those of you who want it, it is 251.0kw at the back wheels in Dyno Dynamics shootout mode 6)

The car is most definatley quicker, starting to feel real quick again however by idle still needs more work as it is a bit rough. We are currently running a modest 10 psi and will increase this when the ic goes in along with better valve springs.

I have only driven a short distance but I think it is now taking the auto a bit longer to change between shifts with a bit of flaring , trust me I will let you know how it progresses.

Cheers,

Dean

Hey Dean, have you had the valbvebody in the auto changed over ?

What other mods do you have?

Is your work being done at Amberley Auto's in Dandenong? I had 233rwkw's without the injectors running just under 8psi of boost. I would have thought that with bigger injectors and 10psi of boost you would have got a little more. With the flaring of the auto, is it at all times or only under hard acceleration? Is it with all shifts or just 2-3 at full throttle?

I will be getting the bigger injectors soon and was looking at the waterspray too. How much is the PWR intercooler installed and what performance increases do you expect?

Thanks Geea.

[geea]

Ok, I have just re-read your first post and seen your mods. I have a 2nd cold air intake and believe that it makes a huge difference. You could try a dyno run with the intake lid off and see if there is a difference. If there is you make want to install one. :o

Hope this helps, Geea.

[xrdreaming]

Yeah I thought I might have got a bit more out of it, but just be warned that the bigger injectors and hard to get right with xede and Amberley needed the car an extra day to get it running well enough for me to pick it up.

I am not doubting their work at all as I am very happy with the way they have gone about things so far and in fact I ordered my PWR intercooler through them today to have fitted next week.

I will keep an eye on the auto as I am not used to driving it with this much power and I notice it between first and second actualy. I will keep you posted.

Cheers,

Dean
