S3 vs a45 and more
 

The a45 has the stage 2 pack from rebellion in the uk which consists of a piggyback box and turbo cost is about 2500 quid, there is a guy in Scotland running 475 bhp from just a piggybox

But just watch how much it nails the new S3 and even the latter video the 650bhp takes it's time to real it in

Mad Italians or something that area lol
Take a look at this video on YouTube:

Not sure what you're getting at here.
The S3 was giving away 140bhp so it was always going to get nailed.
As for the Stang, take away the 4wd advantage of the standing start and the A45 gets nailed in a similar fashion to the S3!

It impressed me that for 2500 quid you can have a very fast car. To get the subaru to anywhere near 440 450 it would have cost you 4 times that and in some cases 8 times. I had quotes ranging from 9k to 18k for a new saloon to 450 safely.

Appreciate that its 4wd but i was trying to think of any high bhp cars that arnt other than the GTR. Not that many about, also that and 170 quid a year roadtax 30 to 40mpg if driven normally does make it fun.... Be good to see what weistec drop in the next month or two, i know there testing a new remap and downpipe for the 45 just waiting for the numbers to come out

Now I see what you're getting at :thumb:

Yeah the A45 is such a nice car, had a good look round one at the local dealer whilst in there the other week, if only I had enough ££££

i didnt realise the price of the car had dropped to that level,,,,,, hahahaha

ok so just the upgrade then lol

M3's can be supercharged and depending on which model hit 550+ but costs about 8k, so not realy at the 2.5k being talked about here though lol

is there any proof its running that? aka dyno print out? uk tuning box's seem to only got to about 405-410bhp

650HP Mustang really misses AWD, you can hear it spinning for ages.

My tune only GTR squirms and slides at the rear in 2nd gear in the dry much like the M cars I've driven, but then it puts similar effort to the back wheels. I can't see the disadvantage of a good AWD system, especially if rear biased, varying torque transfer with steering angle, gear or speed, acceleration, braking except it makes the limits higher. A front biased AWD system can be a bit dull though, but sometimes you want the stability.

But the A45 AMG will cost you 16K more than a Subaru out the box.

Therefore, probably Subaru could be tuned to 450 for less than the capital cost of buying the standard AMG?? and the Subaru has a better 4wd system.

The new tuning box on the s3 is giving figure of 0-60 in 3.7 secongs and 100 in about 9.6

Not a fair comparison really

The stage one gives 405 the stage 2 gives 420 upwards. But stage two includes a new turbo. On the bottom of each tuning box are settings. That if you want can be tweaked. One guys running 475 with just that box.

As for the subaru stuff, yes you could but then we are back at the same arguement thats been done before, high mpg high road. Tax, poor residuals and I could also spend 25k on a 5k clio and maybe get near.

Its a nice gain revo are claiming is it out yet

Im still debateing if i need one

So ive now been told why, because i did wonder how revo did this with smaller numbers, i guess official release wont be as good
I quote

This one is pretty easy to be honest.. Basically the main contributing factor of this is weight. The new Golf 7 R weighs in quite a bit less than our lardy A45 (around 100kgs), so they can achieve similar (although not as good) performance figures to ours with less power.
Also, I know the Revo 7 R quite well and these results weren't done with JUST a Stage 1 tune. The car also benefitted from sticky (road legal) track rubber, lightweight TD wheels and the addition of Revo's own performance intake.
The car is now rocking a full Milltek turbo back exhaust and running a Stage 2 beta file at the minute, so expect those times to get slightly better..

Oh and Stage 1 A45's have seen 12.0 and both were run in crap conditions so expect quicker times soon..


So not a normal,stage one, but still bloody nice numbers, i guess weistec once they release there unit will be similar, i expect revos public release will be slightly slower.

Must get wife a golf R

I don't particularly like the looks of the A45 AMG, but can't deny it has good performance. There is a chap who has run a 12.07 1/4m with a Stage 1 so pretty quick but not earth shatteringly so when compared with what the TTRS/RS3's were doing stage 1.

One of the numbers right anyway...

0-60 = 3.77
0-100 = 8.92

http://www.audi-sport.net/vb/new-a3-...3D-8-92-a.html

S3 running tuning box, no other mods, approx 355hp (So the same as a standard A45) I suspect this will run into the high 11's down the 1/4.

Standard numbers for the S3 are...

Standard - 0-60 = 4.25, 0-100 = 10.45
Tuning Box - 0-60 = 3.77, 0-100 = 8.92

http://www.audi-sport.net/vb/new-a3-...4m-thread.html

The A45 AMG should realistically be compared with the RS3 (RS vs AMG) but that's probably another year off yet. The S3 clearly punching above its weight with the numbers above. 0-100 in 8.9 at only 355hp is pretty bloody quick:thumb:

Hybrid turbo and full stage 2 mods.

I always said it was stage 2 which as rebellion quote is a piggyback tuned to cater for the new turbo they give you

The 475 bhp guy live in Scotland if you search a class forum he talks about it

I'm sceptical too as rebellion state the stock shouldn't be taken past 420 without a change

Aren't the stated time for the s3 4.8 officially ?

What will be interesting now AMG have commented on let the competition begin with VAG what each will bring out, but also the tuners

I'd be happy to see who hits 500bhp first without the need for a major rebuild

I think it's possible

Does anybody know if the e888 from vw is forged like amg or just a normal block

Tbh I think 400 is enough. For any man but I would like 500 . I spoke to acid at MSL in Birmingham and he's doing a 500 bhp a45 but him and weistec and just finalising cracking the ecu. Before it's public be interesting to see how much

But my only concern with all this is the Amg engine won't be cheap should it go pop, vags will be cheaper, taking an engine out of warranty of that coat would be foolish wouldn't you think ?

4.8 to 0-100km/h yes (0-62.14mph)

If you have a look at this thread below, 0-100km/h was tested at 4.5 so 0.3secs quicker than Audi are quoting officially (Audi tend to be conservative with their 0-60's)..

http://www.audi-sport.net/vb/new-a3-...4m-thread.html

0-100km/h = 4.5
0-60mph = 4.25

Stage 1 to most means remap only
Stage 2 to most means full bolt ons. (Exhaust/Intercooler/Intake)
Stage 3 would be a hybrid or big turbo or at least with a hybrid being classed as a Stage 2+

I guess its just terminology at the end of day but most people understand stage 2 as full bolt on standard turbo. With a hybrid turbo, I guess 475 will be possible, would think the standard turbo would run out 430 ish though

ah k, when i read it i thought was just a tuning box lol

I wouldn't worry about the AMG engine Ted. Unless the A45's is a duffer it'll be good for plenty more power. Despite the folklore on SN very very few true AMG engines have gone pop even when tuned. You do get something for all that extra money and that is a properly engineered engine, not last century's tech teetering on the brink of failure from the day it leaves the showroom ;)

Thumbs up F1 straight to the point hehe

A few premature simplifications here about comparative outputs and reliability. It is only 2.0 litres. Cylinder pressures, EGT control, knock resistance are all inevitable issues. Many consequences of tuning will not show up for some time. 500 BHP for a few months is much less of a test than 400 BHP for 10 years used hard without a rebuild.

In terms of results from a given tuning level it will (if the issues below are secondary rather than primary limitations) depend on turbo housings and wheel sizes. Other issues are remaining injector/pump flow, and where the bottlenecks are in the intake (including intercooler) and exhaust systems, as well as compression ratio, combustion chamber design, cooling, knock resistance.

Personally I'm expecting 150 BHP/litre to last 10+ years. I'd be lucky for 250 BHP/litre to last 5 the way I drive.

Weistec seem to be attacking the ecu and Downpipe first over a turbo upgrade, not sure why, but they seem to know thre stuff.

Anyone care to elaborate, wont downpipe effect emissions or something else

Downpipe will house the cat, get rid of the restriction and you can run more boost and a little more timing as it will naturally lower the EGT's by clearing that restriction so close to the turbo. This is where your biggest gains are after a remap.

Yes, it will effect emissions but if they adopt a sports cat, 9 times out of 10, it should pass, if a decat, it would fail.

Turbo upgrades come after full stage 2 type mods, makes sense to look at exhaust/intercooler/intake before you touch the turbo.

Ease of fitting, cost, where they feel the bottlenecks are etc. Removal of an OEM catalyst, or change to a free flowing one may leave other cat(s) that easily allow it to pass the sniffer test, but is probably not legal, and will probably get tighter in future years.

You seen the reported "issues" C63's have had on mbclub?
Not necessarily total engine failures I should say.
Just saying......................

Nonetheless, the AMG cars would appear to be pretty sound thankfuly

Leo, have you still got your TTRS and are you still local to Dundee??

(Apologies for off-topic comment..)

We'll I'd worry if I had the 6.2 V8
