Supercharged RS4 Vs Stock RS4

[Shadow6ix]

Another voice to vouch for the V8 + Supercharger combo. Exciting to read this thread... Looks like I won't have pine after the Monaro too much when it's gone after all!

Little vid some might appreciate... Maybe: http://www.youtube.com/watch?v=nxW5riSdH1I&hd=1

'Ro's have a great sound. Used to know two owners, MOSE and BO55VXR (Bo55 has a greens supercharger, MOSE Wortec headers and full decatted exhaust) who had their cars regularly featured in VXR magazine. Nearly killed two old biddies in the Lake District a couple of year back started both motors up at he same time! You could hear them coming from 2 miles away!

I know Bo55 from the forums yeah! If I can get half that sound back from an RS4 then I'm going to be a pretty happy chappy.

Always bothered me about the Monaro along with the knowledge that only 3 people in the UK want one, so once you've got one, you're going to find it hard to get rid of...

That car always seemed to me like the triumph of brute force over ignorance. Evo mag thought it was great fun because you could light up the rear wheels by just touching the throttle.

That said there's a Bathurst lurking around here I see every now and again.

The thing with forced induction isn't the headline bhp figures - you need to take a step back and look at the low/mid torque and the area under the curves.

Absolutely...if you want your big power car to be a daily driver or its where you spend most of your time 800Nm of torque between 2-4000rpm is of much greater utility than 550hp at 8000rpm.

For me if you can put a C5 RS6 twin turbo setup in the B7 chassis for £12K + whatever you can sell a second hand B7 V8 for, I'd be keener on that if only because there is infinite tuning potential with this setup...

If it can go in a B5 chassis....

With that set up at least you wouldn't have CB......




































I'll get me coat!

Here is the V8TT in a B5 chassis:

And here is Doug's C5 RS6 manual conversion using a B5 S4 01E gearbox:

Now dump the whole lot in a B7 chassis or just hook it up to the B7 gearbox - superb - and wow....what a package....

Whats the guess the next B9 RS4 will come with a twin turbo setup anyway...

[P_G]

No doubt, a V8TT would be great again but I suspect that will be reserved for the RS6 to put it head to head with the new M5. I reckon TSV6 but it will still have FSI which may be the Achilles heal in some eyes.

V8 4.0 Bi - Turbo

going in the RS 7

[P_G]

Thought the RS7 was getting the last of the bi turbo V10's?

[Doug_S2]

The gap in 4th is around 5 car lengths - but that video the supercharged car only floored it after the NA car started to floor it.

I have seen all the comments about that kit - I know we map these cars better than anyone else has. Just the airflow the charger flows were good and then gains we got from playing with inlet and exhaust cams means this defintiely runs better than the US ones upto now.

At the end of the day I know 90% of healthy standard car does 370-390 on our dyno, cleaned and ported do 410-430ps and this supercharged does 515 consistantly.

I will have a B7 soon and hand th ekeys over to any b7 owner to test the kit.

Doug, just to be clear I'm not doubting what you are saying or have done to the car however as you have read so have many others and it is always harder to overcome negative press than put out genuine positive news.

How much power do you reckon the s/c is losing between parasitic losses and heat soak; 60hp?

[Doug_S2]

It must be around 55-60ps lost - just rough airflow numbers show that 230g/s x 2 is 460g/s total ingested air and the usual (rough) power conversion is divide that by 0.8 - it is usually accurate for cars mapped well.

[P_G]

So the gains you get are better than in the US as the common numbers thrown around are the unit is good for 160hp but half is lost (son only 80hp) and you are getting the power that is seen in supposedly more efficient s/c's in the US.

[Doug_S2]

I think the gains we get are better.

very nice, looks VERY quick.... got to stop looking at it NOW!!!
