Most power made from standard turbo??

[duncanhancox]

i forgot to say that for practical purposes, the top end hp figure is really irrelevant.
the better the torque, the lower it comes in, and the longer it is maintained, the better the engine is to use on the road. the big turbo conversions trade off a few hundred revs at the bottom end for a considerable increase in top end torque maintained far higher up the revs range. This means that as you stay in gear, the engine pulls stronger and stronger, but you may find an increase in lag (possibly not with roller bearing turbos) and the car will need between 200 and 500 revs more to produce the same bottom end torque as the k04

Ryan, if you win the lottery you could always go for this conversion:

SPORTEC double Injection-System 460 bhp, 520 NM Conversion for 1.8T consists of: high performance intercooler with piping, high performance radiator, oil cooler with hoses with lines and bracket, power steering radiator, Sportec high flow Turbocharger, Turbo intake with hoses, stainless-steel handcrafted exhaust manifold, engine mount bracket with silentbloc, airflow optimized intake manifold for double injectors, fuel rail for 8 injectors and regulated fuel pressure, big throttle body, crankshaft for 2 litre engine conversion, conrod bearings, 4 reinforced connecting rods, 4 pistons for 2 litre conversion, 2 sports camshafts, 1 modifies cylinder head with ported inlets, modified flywheel, sports clutch, 4 injectors, gasket kit, double injector controller, modified engine loom, air flow meter, exhaust downpipe, ECU remapping and dynotests.

Thanks for the info.After heavily tuning my previous car i was just trying to get some basic info about the stock s3 engine.Obviously the injectors are just good enough for 300hp(maybe) then the stock block/internals good for 350ish bhp.I wouldn't say that fuel pressure changes due to increase boost ,i would say that injector duty cycle increases as boost is increased .I would imagine that the s3 has a standard fpr which increases to fuel pressure to a certain set level.eg 3 bar.A adjustable fuel pressure regulator could be used to increase the amount of fuel flown but by a max of 5%.Dunk,i think you mean area under the torque curve.Although this is a factor you don't really want your turbo to run out of steam at 5k(if running out of range)k04 at 1.5bar for example although i understand what you mean.
I'm probably thinking of fitting a motec or omex stand alone first and really see what the standard turbo and injectors can do then fit a gt series garrat turbo probably a gt 25 or gt28 to around 350hp.
Anyone heard any reports about the omex? They used to well known for applications on na cars but i'm not too such these days,regards Ryan

Found out that all s3's run 386cc injectors at 3 bar.Theoretically giving a max bhp of 250ish??!!!Seems odd,i'm going to have a chat with a tuner friend of mine to see how they squeeze the extra ponies out?regards Ryan

[DuncS3]

I thought the S3 had 4 bar for the injectors?

Could be wrong, although I am sure the Golf 1.8T (150 bhp engine) people fit the 4 bar regulator to chipped cars.

that tells you all injector sizes and fuel pressures for vag 1.8t's including u.s.

hope that helps,regards Ryan

Good link Ryan, cheers - My S3 has the BAM engine code, and I can see it lists a 3 bar FPR.

Keep us informed of your progress, as this techinical side of things (different ECU etc) is interesting.

Cheers

Ryan,

Actually I am not sure that information is correct, I have read elsewhere that the TT (so S3 too) has a 4 bar FPR.

I will email one of the tuners and ask them this week

Hi Dunc,
My tuner ,dino from "owen developments" says that they will be getting the revo in soon and it is apparently v.good(well as much as a piggyback can be).I ran a unichip(piggyback) on my previous car for many years and was v.impressed with it,although they seem to be less popular nowadays(maybe revo is better?)I will probably go full standalone which means motec etc.Although alot of the benefits is created by the tuner himself rather than the equipment.G-force and owen developments are top tuners so i'll probably go to one of those although john noble is meant to be good to.I'll keep you informed and might create a faq for newbies like myself to help things along,regards Ryan

[Ryan_s3]

Have heard from 2 sources that it is a 3 bar fpr although it doesn't really make alot of difference to the overall amount of fuel delivered 5% maybe.regards Ryan

[DuncS3]

I've dropped a email to Revo, find out what they think.

Cheers

For more information on engine codes have a look here:
(Remember to look at the European 1.8T codes though.)

REVO have told me that the S3 has a 4 bar FPR

Which I believe to be correct.

I know that REVO have a 3 bar (standard) program for the Golf 1.8t (150 and 180 bhp engines), but they also have a 4 bar FPR for these engines if you upgrade the FPR.

Cheers

interesting dunc,did they confirm they they where 386cc injectors?Ryan

[DuncS3]

I am being told they are 360cc...
