Title: Std 200bhp GTi figures
Post by: scooba on July 07, 2012, 11:05:50 am
Hi , Firstly I hope this is in the right section please move if I have posted it in the wrong one

I was in the hair dressers this morning and listening to a lad go on about his 266 bhp map he had put on his 55 plate GTi , He claims the car is std stock car and has gained nearly 70 bhp  , is this likely or the guy who sold him the map being a little bit bold with his figures, I realise 266bhp is easy enough but just by a map ? and nothing else  this must be near the top from a stock . Any advice guys

266bhp with just a map on a 55 plate GTI is possible if you go on a very very generous dyno. Reasonably I'd think 245-255bhp. :smiley:

Have a look at the JKM website. They have the results of various cars at various specs and you can see how much bhp they produce.

Superchips reckon I will get 260bhp from my car at stage 2
And that's with a full exhaust and induction kit.

I have heard there dyno is very optimistic and will be getting mine on the rollers at Wallace performance soon as there rollers are quite accurate

motech reckoned id get 255bhp  :signLOL: ended up being 214bhp  :sad1:

Until r-tech nick came and saved the day.

So my mate is only kidding him self then .TBH I thought it was vey optimistic. I realise it is possible but  just a map and I don't even remember the name of the guy who did  it

as said above dynos are lottery and not comparable. Generally speaking JKM dyno which is widely recognized to be more realistic then optimistic claim aroun 230ish with a map

A stage 1 TFSi map will be roughly about 240bhp with no other mods.

....I don't agree. I think you need at least a high-flow TBE to make ~240 bhp on Stage 1 on a K03 2.0T FSI.

Even on JKM's dyno 235-240 is possible  :happy2:

Mine has R-Tech Stg1 map with K&N panel & pre-cat removed and I got 241.3 IIRC at the last day. . .

My Shark stage 1 made 236bhp on Rtechs rollers with a small boost leak (hence why it was on there to find it) so 240bhp is possible with standard hardware and just a map.

It seems I may be wrong about some performance hardware needing to be added for any significant Stage 1 gains.  :ashamed:

I wouldnt worry about it. I get told Im always wrong by the missis. I plead ignorance and carry on :rolleye:

56octyvrs,what was the outcome of your boost leak,reason i am asking is that i have recently had a k04 conversion done and my tuner cant find my boost leak,stating that my car is venting boost pressure into the crank vent,this is after checking and replacing all the usual suspects,boost switch,dv,all replaced new,and has done pressure test all hoses checked its starting to do my head in lol

Hi Dougie,

You have possibly read this already but it's worth me bringing it to your attention just in case something in my thread helps you:

I may be wrong but one thing to always remember rolling road figures are only to give a therabouts figure. They all make a prediction on what they think the engine is making once they have calculated power loss through the transmission etc. I personally only take whp figures unless the engine has been on a dyno but that's not really cost effective! average dyno figures vary but 230 ish area is the norm and I would say realistic from a stage 1 gti.

Dougie, did your car have a boost leak before the conversion? Who has remapped the car as the fault code might be from the map itself.

i made 239.8 bhp when i had my shark map and the car was totally standard.   :P

I think this has already been said but, stating Stage 1 bhp numbers from various rolling-roads on various days with many various operators, simply isn't reliable. Unfortunately it's a well-known fact that rolling-road results are a lottery and there can be huge discrepancies. Tuner's bhp claims are also unreliable.

I agree with said statement... this was on some of the most accurate rollers.

hi redrobin thank you for your reply,yes i have read your topic on boost leak but just wonderd if anyone new the cause of mine,as i am hoping it is not my k04,as to was the boost leak there before the conversion i dont think so car pulled very well,i have a custom evolution map on my car with various other mods itg cai,vwr tbe,new s3 dv,why would it be venting boost pressure through the crank vent down to the sump?the search goes on :surprised: thanks guys for your info

Fuel plays a big part,  a good stage 1 remap with v-power will make around 238-244bhp. The restriction for going over 250bhp on stage 1 is the cats imo.

the only way he would have made those figures is with a mk6 gti  :innocent:

Post by: R-tech-Nick on July 11, 2012, 05:04:38 pm

After looking at 100s of mk5 K03 logs and playing today I have found the limiting factor for stage1 power is pre turbine exhaust manifold back pressure and flow via cats.  At stage 1 the n75 duty can be 100% from 4000-7000rpm and still make 238-243bhp maxed out about the same power window of using 87-90%  duty cycle.   Which is telling me the waste gate flap is being pushed open from the manifold back pressure.

 Now remove pre cat and add around 6-7mm pre load to the actuator and run 80-89% duty at the top end and we have 255-260bhp.. :happy2:  Only issue is that on the intial spool up the boost gose way out of MAP sensor range,  so some work needed doing on the n75 maps to stop the spike.   

I still got lots of testing and logging to do when I get back from Holiday, but I think there is a lot more power to come from the k03 at stage and still be safe.

Great info here Nick! It's good to see somebody trying to open closed door as it's the way to go progress wise!

Removing the pre-cat is a fantastic "cheap as chips" mod  :pomppomp:

Looking forward to your your new mapping ideas Nick, I'll be coming to see you later this year for a linear throttle map and your more than welcome to have a play with my map  :grin:

This is the most we ever see on K03 without precat removal on 95ron fuel:

 


And with 98ron fuel:



With precat removal and the boost spike that Nick mentioned resolved we can see 255-263hp on occasion.
