bigger injectors?

Like I say.
Compairing against another car isnt reliable.
Even a warm flywheel can cause a diffrence in the power output.
If you have a hot flywheel you lose power.
The weight issue doesnt matter when the cars are idental.
But tyre width, firmness of side wall and pressure has to also be indentical.
The speed in which they accelerate through the run also has to be matched.
The engine temp can also alter power output, so the runs need to be done when the oil temp gauge reads the same temp.

But I am genuinly intrested in what you have done to your engine.
27hp over standard even if these things were not matched is still pretty impressive from the stock ECU and induction.

I dont have enough time to search at the moment, but if you could post the link I would enjoy the read.

I seriously dont understand why i should be the one giving you the links, when you are just too lazy to do a simple search....

Anyway...This is a thread that shows the changes i've done, but it is a bit older and some "extra" mods have been performed since.I am NOT although going to reveal what those are exactly, for my own reasons.

Read away....

Very impressive.
Same sort of mods Ross has done to his Lupo and the same sort of results.
I belive he got 160hp after the remap as you'd predicted.

I take it you have used 252 profile cams?
Do you think these are enough?
I belive the 100hp 1.4 engine uses 248 profile cams, although I do not know what the GTi has as stock as Ive never concidered using a GTi head.

How much ajustment did you find the stock ECU had?
Ive seen print outs of a few remaps, and all still had the dip in the power and touque curves around 2.75-3krpm.
Were your mappers able to remove this?

Just to throw another spanner in

You can get more power out a pair of twin webbers than a turbo, if thier are set up right..

hey tigz remember you said to me about putting mk 4 golf gti tb on my polo, well some random came up to my brother (cuprabaz) when he was off shore and started talking about my polo and the guy said to put these the golf tb's on. cut to the chase, do you no much about doing this??

I dont mate.
I just remember reading about it.
I couldnt tell you if it would fit without any mods.
Its possable it may just bolt on, I couldnt tell you for sure as its not something I ever looked into.
I know after you replace your throttle boddie, you have to get it set by VW.
Even replaceing a cable operated throttle boddie requires this from what Robin was saying.

I have just given mine away as a dude was quoted Â£411 for a replacment Lupo one last week!
Alot of cash for a butterfly eh?

As i've already told you, the dyno i went to is considered REALLY conservative...The car might even be 10% off the real HP downwards.
I am using 256/244 Scricks but the horsepower isn't in the cams.Its in the
Gti head and variable intake.The cams are REALLY extreme for the engine.I was able to determine stock cams are in the 215 range...You get the idea...I would imagine an exhaust tuned that hasn't yet been performed should give me around 10+ at the fly.

As for the dip, it is present in the stock ECU software as well, althought my programmer said it looks very accentuated due to the way the graph is laid out, meaning he had to process it, to make both curves fit the paper.After the latest modes i performed it is now also unoticable on the road as well..

There is really A LOT of hidden power in this engine.....Trust me ...I know....

I know f**k all about any of this... but!

The readings of wheels speed sensors are transfered to the ECU to adjust braking "per wheel", and as a plus using the EDL feature reduce sliping at corners and slipery road surfaces....But then again...you had NO IDEA...

This EDL feature is the f*****g s**t!! My Gti has more grip in the wet then my old 1.4 had in the dry. This is bearing in mind that my old car had Toyo Proxies and my GTi has michelin tyres...

Phill.

I completely agree with you there.
There is a very intrested couple of posts on the subject Here
Ive also found one of your first posts on the subject of cams

Im not even concidering the cams yet, as I would like to get the crank replaced, wheelwheel lightened, induction and exhaust sorted first.
Once mapped (and Ive sold some body parts) Id like to get some cams built.
I think I will stick with the 1400 head, I belive the GTi set up is too complicated to be able to get done cheaply.
And finding someone with the skills to build them wouldn't be easy.

But even with this side of things sorted.
The stock induction is poor.
The heat build up around the TB cant be good.
I cant belive the diffrence in peoples 1/4 mile times at 'pod this year.
Cars I saw do the strip in 16.0 were struggleing to get under 16.5.
We maybe had a rise of 10 degrees c' from the same time last year.

We've seem that dip on both petrol and oil burners.
Id always imagened it was for fuel econimy, but after seeing a couple of remaps at AMD, both cars retained this dip.
I was unsure if it was something they are unable to smooth out.

I'm glad to see you are begining to realize the work i have put into this engine, and the level of knowledge i've gained about it.

I have tried to make this clear from the start............

P.S. I just realized even my name is quoted in the post you linked, without my knowledge...Didn't know i was that famous...

lol this thread will be famous

never doubted you had some knowlage there mate.
I dont claim to be any expert in any of this.
But I have had help from some very clever 'mentors'
The reserch I have done is limited to induction, ignition and just starting on the mapping side of things.
Rolling roads was the first subject I read up on.
Im not even attempting to learn about cams till the engine is running and Im bored of the extra power from the boddies and ECU.
Taking too much on in one go is never wise

Right ladys i went out in AMD's r32 supercharged golf today and that is a serious piece of kit!! Pant messing stuff!!

0-60 in 5.1 (in wet)
330bhp 300lbt

F U C K the turbos i want a supercharger for the polo and AMD say it can be done!!

So lets strap superchargers to the GTi's like a bunch of lesbians strapping dildos to there crutch's!

Im starting my fund tonight!! 10p 20p 10p 5p (long way to go)

Si_GTi · Post by **Si_GTi** » Fri Jul 29, 2005 7:58 pm

Sounds like fun. The supercharger idea too

How much are AMD asking for to do a supercharger on a Polo GTi then?

PhilGTi · Post by **PhilGTi** » Fri Jul 29, 2005 8:19 pm

Id be interested in this little plan!

Probs about 9grand tho

.

Phill.

poussou · Post by **poussou** » Sat Jul 30, 2005 11:35 am

Yes Moyas plz check for prices and if there can be a complete kit too.

There are people with no access to AMD....
