Car goes in to Bruce from tomorrow on. Leaving work early tomorrow to pick up a jerry full of E85. Looking forward to seeing what Bruce can get out of this setup.

If anyone visits Bruce & knows numbers/figures before I get back, please show some respect & do not post it on any forum. Thanks.

Hey fellas,

Just got the car back from Bruce.

Bruce wasnt at all enthusiastic about what had to be done to the car. He was getting to a point of giving up so he said. I must admit, when he did call me I though he torched the car as his manner over the phone was less than impressed.

I have mixed feelings of the results but overall I am happy.

I'll start with the bad points:
-He couldnt fit the thermo fan due to lack of room behind front bumper.
-He had to hack the top of the grille to get access to the heat exchanger.
-He couldnt get much more power out of the BP ultimate fuel.
-The 2.5" exhaust is now far too restrictive for more power.
-The smaller boost pulley has made the boost remain the same as before but this could be due to extra pipework that had to be added.
-I got slightly less power than I had expected. But I think that was due to restrictive exhaust.
-The injectors were at their max with the E85 tune.
-I have reached the maximum I can on an unopened motor.
-Its cost more than I wanted to get it all fitted

The positives:
-I reached my initial goal of getting over 200rwkw
-All the parts fit under the bonnet.
-The cooler core is cool to touch after a hard run
-Heaps easier to peel the tires now
-Heaps more response and torque
-No pinging at any temperature
-The engine feels stronger (could be a placebo effect)
-The water pump sounds silent when operating
-0-100kph times feels quicker
-Did I mention the torque??? Oh yeah, more torque definitely.

Run down of power outputs:
On BP Ultimate I got the best of 180rwkw (safe tune)
Remember a while back, I had the car tuned from Bruce for a dyno day last year and got the car tuned just for that day at a best of 194rwkw but that wasnt a fixed tune to the flash tuner. That was just for the dyno day. I only achieved a 194rwkw output after 2 runs on the dyno on a cold day. All other runs were risky with pinging evident. And that was the main reason why the tune wasnt a permanent one set to the flash tuner.

On a 60/40 blend of BP Ultimate and E85 fuel. I got the best of 205rwkw (safe tune)
One thing I noticed was the tractive effort torque had significantly increased.
Its not a mind blowing increase, but I was told the restriction was the cam and exhaust holding back decent numbers. Bruce had to spend a number of hours trying to extract as much power as possible but found it to be difficult due to the exhaust size and limited ability of the stock cam.

Refer to dyno print outs of before and after. If anyone can convert the tractive effort from the 205rwkw readout to Nm Id appreciate it.

Boost was kept to 9-10psi which was basically where it was prior to the intercooler being fitted. I figured due to the extra pipe work added and the smaller boost pulley being fitted it remained the same.

The pipework fromt he supercharger to the cooler is 2.5" mandrel as that is the opening size outlet that the supercharger has. There is a silicone reducer to connect the pipe with the 3" inlet of the cooler.

The pipework from the cooler to the TB is 3" mandrel.

I think having the 2.5" pipework initially has helped with the extra throttle response. This I found evident. Leaving the premises onto the main road, I found it easy as to light up the rear tires in first 2nd and 3rd gears. The torque is also noticeable.

Ultimately it is doing what its supposed to and that is to keep the intake temps cool as possible in degree any day. The extra power is a bonus. The lack of a thermo fan on the heat exchanger Im not sure how it will effect the water temps. Bruce reckons it shouldnt play too much of a problem when I get moving. Plus he reckons the twin thermos already on the car are already drawing air in while stationary anyway so it still is getting some air flow, just not from its own dedicated thermo. A good city drive will tell the story I guess.

Would I recommend this mod? In short, yes, but only with a 3" exhaust system and a cam to take advantage of the cooler air temps.

I'm in 2 minds as to whether I bother with the exhaust option at least of just enjoy it as is.

shav thats not bad..
i got to say i had to spend and do more than i thought to get the 200rwkw.

but dyno's are a little misleading. i went from my original tune figure of 174 rwkw to 2nd tune of 194rwkw then did mods ,exhaust,more boost and on a dyno day it only pulled 186rwkw..
but after it had the exhaust and extra boost with the 186rwkw it felt like it had more go than it did when it had the 194rwkw..
i then changed the cam and on the 3rd tune it made the 203rwkw but i still need to fit larger injectors....

imo aslong as it puts a smile on your face its money well spent ...

thanks for the reality check Troy. Sometimes i get down on my expectations.

I guess i aimed a little too high

dont worry so did i.
im still extremely happy with my results, at the end of the day our engines are still pretty much stock,
i think the thing you will notice with the w2a set up, is now your power will be consistant,
where in my case as heat rises power drops off..
i still want to intercool mine but dont want to spend the money..

I hear ya there Troy. Im getting right fed up of the cash Im throwing at the car at the moment for little gains. That being said, the car feels stronger almost all the time now, not just first thing in the morning. Thats something that bothered me for months especially when in a traffic light duel...lol

Having the E85 blend too is something Id also consider next time you get your car tuned Troy. Bruce set up a special tune just for that fuel blend on my flash tuner so if Im feeling adventurous, I'll fill up 20L of E85 and the rest BP Ultimate and go for a real squirt. I also have the BP Ultimate tune also. Albeit tuned for safe running, lower power and better economy. Seeing as you have a bigger exhaust than me, I reckon you'll see a 10rwkw increase with a E85 blend tune. You can definitely fell the difference, but it also chews thru the juice a bit quicker.

i love this !!!!

haha thanks for ya comment.

Hows it going guys, been ages since I have updated this thread. Here is some fresh pics I took last night.

Cheers
