Most power made from standard turbo??

[s8n]

Hmm, i find this hard to believe. Standard 360cc injectors wont flow much more than 320HP. If you are pulling over 400, you'd need new injectors and a new fuel line plus a AFR I'd say... I don't see how you can be running rich !!! If anything your mega lean..

This is some S3 you have..

I cannot even see how your managing that power! Maybe 408 Greek Ponies = 300 Aussie Ponies [img]images/graemlins/roflmao.gif[/img]

S8n, mate you could perhaps be a bit more friendly to a new poster!

Anyway, there is a guy with a TT here in the UK running REVO and NOS - his figures are 360 bhp - and his mods and times are:

Revo 265 remap
brembo brakes
fmic
milltek exhaust & cats
nos kit(360bhp)
0-60 5.14
0-100 12.20
1-4 mile [email]13.58@103.67mph[/email]

The times are from Santa Pod and alledgedly his car was running 330 bhp when times rec

hhe.. I just like claims to be backed... Soz aro

360hp is a bit different to 408 & 580NM! [img]images/graemlins/smile.gif[/img]

Im sure the revo guy has modded fuel system...

360 is believable I think, because the injectors/fuel system in the S3 might take that!

Anyway, would love to see graphs!!

So here is my time as recorded for a greek car magazine last Tuesday :
With nitrus 0 - 100kmh in 5.0 seconds
1/4 mile 12.6 secs
Without nitrus : 0 - 100 kmh better 5.4 and 5.9 secs. Average arround 5.7
1/4 mile 13.67 secs
I believe that i 'll have the dyno graps this evening.

Thats impressive

Please for me, and the rest of the forum explain how you acheieve 230kw from the stock turbo and fuel setup?

Thats alot of power!!

According to some figures ive punched into some calculators, 300.5kw = 404hp. based on 1420kg, 3124lbs and that power, your ET would be around 117mph with a 11.5sec qtr mile..

Hmm no offense but doesnt add up!!

Anyway, would love some more info on your mods!!

400hp from our engine on stock turbo is crazy with gas

[aroS3]

First,
As you know it's a little bit difficult for a car to drive without a driver... he.. he..
Anyway, in my occassion there were 2 big guys in the car, me and the guy from the magazine plus the metric equipment a laptop e.t.c, the Nitrus...some ice....plus that i have the electric roof that weights 70 more kilos (1490), you want more ?
Now do your calculations again and see if your numbers still don't fetch with my 12 secs.
My mechanic is also my cousin. His previus S3 reached 325 hp with stock turbo and head mods.
As for my mods i dont have anything else to say. There are all in the list above.
Regards

[s8n]

Perhaps you can ask your cousin what boost pressure he is running and how you are able to acheieve such high power without NOS?

You are the only S3 225hp engine i know to break 300ish horsepower with the standard Turbo.

Hell if I knew how to acheieve 300hp out of my car without the gas and standard turbo, I'd be doing it!!

[Ryan_s3]

Are you running on race gas(petrol)?I can't see how 360cc injectors can handle 300bhp let alone 300+bhp.I strongly suspect the s3 injectors are 430+cc.I had a set of 430cc's max out at just over 300bhp,monitered by motec.regards Ryan

[R88PER]

George - welcome to the forum. [img]images/graemlins/thumbs.gif[/img]

Those figures are really good. I think the reason people are a bit cautious, or cant comprehend how you have gained such good results from the mods you have done, is that there are a couple of guys frequenting the forums who have done similar mods to yours, who have only gained around 300-320bhp max without changing the turbo. Although I dont think any of them have changed the cams or done any headwork. But youve shown youre worth and printed up the plots which prove it so that'll do me.
I would be interested if you could elaborate on some of your mods though. Are you running a larger intercooler or are you on the standard ones etc.

Some pics would be good also. [img]images/graemlins/wink.gif[/img]

[s8n]

Ryan, they are 360cc injectors. Not 430.

I've done some research on the stock turbo, and found some compressor maps. Our k04 on the S3 Engine has a effecienty (works best) at 1.1 bar with around 138,000rpm compressor shaft speeds. It is 0.75 efficent @ 1.4bar/1.5bar but beyond this you reach spindle speeds of over 170,000rpm (very bad for turbo). At 1.4bar, the PR is about 2.5 (air exiting the compressor housing is 2.5x the pressure as entered)

Here is the Compressor map



Thought this might be some good info! Apparently, the turbo is good for around 240flywheel horsepower at safe levels..

[aroS3]

The BAM injectors are 386 as mentioned as well from a friend in the topic before. Mine showed 390 in a recently volumetric test..
Thanks for the KO4 maps.
Regards, George

....Ryan, they are 360cc injectors. Not 430.


s....

[Ryan_s3]

Well it seems according to the pages listed above that europe got the 386cc injectors while the u.s/rest of world got the 360cc injectors(like in the us tt).Also confirmed by our greek friend.regards Ryan

[Ryan_s3]

Just had a chat with my tuner about the s3 and there becoming revo dealers,so i might see what they can achieve with this first.Injectors-v.small as i suspected and will need replacing to 440 if going to 300+ bhp.These may have to be controlled by a standalone but he's not totally sure.
The compressor map shows theoretical safe power output of 230bhp although revo claim a max of 280bhp.The k04 turbo isn't the strongest unit and he recommends a ihi unit with a decent cast manifold for 330-370hp.He reckons 260-280bhp if your lucky with the revo,although this is a max figure due to the stock manifold which is a restriction.The clutches can be a bit marginal in terms of what they can take, even with a chip upgrade. It seems the options for
this car are either a Helix clutch, or a hybrid using a VR6 pressure plate.Anyone had problems with their clutch after a chip upgrade?upgrades?The engine is strong with mahle pistons and can run 1.35bar no problem.
more updates soon,regards Ryan

[bjacks]

My clutch started slipping on my S3 after about 10k miles after the Revo treatment. The car had done mid 30's miles.
I've heard of some people replacing every 20k miles. Uprated like MTM items are stronger and last longer.

If you want help with the IHI turbo, then call Jabbasport as they do that conversion with the sort of outputs you're talking about.

Cheers
