My APR Supercharger has arrived!

[mutantfatcat]

James called me to let me know everthing has arrived and is now in stock, so I took a trip down to JBS yesterday to take some pics.



Supercharger in shipping crate.

















Full kit including Milltek decat downpipes.





Sachs clutch kit.

Go on hit me, what was the tax on that?

I think he'll have the price up on his website later today. Don't forget, clutch, downpipes and exhaust aren't included.

APR is nice, we do a stronger clutch kit over that item but still using Sachs

Looks v.nice mate, i saw the pics on JBS FB page, cant wait to see this in real life and here the sound it make we need another logging session so we can see it.....

Yes you do and a good clutch it is too!

Haha Dan, yes, we'll get another logging session in soon bud!

Will you be using the APR map or will JBS be doing a custom tune?

I may well start with the APR map but will keep you posted.

[LOBA Si]

any idea when the project will be completed ? really looking forward to results on this, bet not as much as you!

good work sir on going for this kit

Thanks Si, the car hopefully should be ready this weekend. Not sure when I can get some dyno plots done as I'm quite busy with work at the moment. May have to take a day off! I'll get some pics up of the kit fitted though.

i thought JBS had inhouse dynos ?

I think he's getting a new dyno fitted.......won't be ready for a few weeks though.

[mutantfatcat]

Finally fitted!

Some more pics

The radiator can also be ordered in black (not as efficient as silver).

Dyno plot




The dyno operator noted that the plot seems to have shifted to the left slightly (red line 8000rpm), despite the fact that the tacho pick up lead had recently been replaced.

Figures were measured at the wheels. I for one don't buy into this 'guesstimated' crank/clutch horsepower nonsense that helps manufacturers/tuners post 'big' numbers for marketing reasons. If you're into crank figures do your research, but it seems to me that % loss for quattro systems are often quoted as being 23-25%. Either way, I couldn't care less....until there is a proven, accurate cost effective way of measuring crank hp. Besides, the best comparable data is generally US based, all quoted as wheel horse power.

I wanted to measure for worse case scenario and not cold runs (well as far as I can go with 3 dyno runs). Luckily, the weather was warm, with the in dash temp display showing 27.5 to 29 degrees C. I ran the car hard for about an hour. It was then parked in the sun for about 15 minutes before being dynoed. Ambient temperature at the dyno was 30.91 degrees C. Three runs were conducted and all were similar.............and there you have it, 453.8bhp with 409.19ft-lb at the wheels.

Very nice!! How is t now then compared to before?

Well what can I say.....
Don't take my word for it.....pm Sandip, he'll tell you...

[solaris]

Wow that looks fantastic, I love the APR kit for completeness and good quality craftsmanship. I can't wait to see/hear your car as i'm too contemplating charging an RS4 in the near future.
Great torque curve by the way, this is going to be a monster when the ambient temp get low in the winter

[mutantfatcat]

Thanks Solaris, if you're going to ADI, come say hello mate!

[N8]

Been hearing alot about this car!!! Good work fella

Haha, thanks N8!

[mutantfatcat]

The above numbers were 2 up with full tank of fuel with 1 foot roll out NOT activated.

[N8]

OMG, I need to see this car man, sure we'll catch up @ a meet sometime.

We will indeed N8

[mutantfatcat]

Driver only, full tank of fuel.

[S3 Rav]

Very impressive that!!

[Matt_S]

This makes me go green with envy... The RS4 isn't enough for some people lol.

Luckily BHP figures are long gone, it's all about top MPG :P

Looks awesome though! Bet it's amazing to drive now!

[mutantfatcat]

Ok, sorry for the lack of updates, been absolutely hammered at work!

I've been running the latest ecu software written especially by James at JBS / Custom Code for the last week and a half.
It's quite an improvement over the original APR software with a very noticeable increase in torque especially in the mid range.
Deceleration while staying in gear after hard acceleration has greatly improved too and is alot less violent than before.
There is now a more distinct difference in throttle response/aggression in 'S' mode too.

I got a couple of friends (who had driven the car previously) to drive the car without telling them it had new software installed.
The 1st one 'gave it some beans' immediately and noted straight away how much harder it pulled through the gears.
The 2nd one took me for a long drive around some fast twisty A/B roads and finally onto some motorway. He commented on how more responsive
it felt and how much harder it pulled, then summed it up with "f**king awesome!"
The first question they asked was "has the boost been turned up at all?" (they're both turbo drivers). Nope, boost still remains at
between 6 to 7psi on the standard pulley.

The following PerformanceBox times were achieved using this software on JBS's heavier avant.




All in all a great all round improvement to performance and driveability........I'm even happier than before!

I'm hoping to get some in gear acceleration times done when I get some free time.

As far as I know this software will be available to all APR dealers via APR's servers somepoint soon.
