Hi, I have just seen a mk3 gti 16v that has been chiped to 178bhp.
I was wandering does anybody know if this is possible to do and how much it would cost to do, and a location?
Any negatives to having it done? :shocked:
Thanks
Chris

Forget 28hp from a chip on a NA car, it's not possible and if it is it'd only be on cars with race engines.
A few of us here run GTI's with chips from pepeoi, a seller off ebay. Mine was dynoed with and without a chip and there was a 9hp difference.

My 16v made 9bhp and that was a custom mapped chip........... :smiley:
-
And how much did you pay? I only paid £30.
-
£200 :grin:
But I did get a before and after dyno
-
Decent for custom map, but ouch!

I'm one of those people. :smiley:
-
Would you say the extra 9bhp is worth it??
-
Yes. It's not just 9hp, but more torque, more linear power and also better mpg when driving sensibly.

As Khare mentioned I had a good increase in torque all across the rev range, I can't remember how much without digging the graphs out though.
It made it drive nicer too so yes, I would say its worth it.
-
Cool, where would you recomend getting this chip from?
-
I've just sent you a PM fella.

Before and after

Red line is before, yellow line is after.

i've got one of these chips in the post..
-
What else have you done to your car?
I have done modified air box with K&N filter, Magnex exhaust and ported throttle body and along with a new chip most I have ever got is 155bhp
So dont expect 9bhp out the box with nothing else done.
I does make the car more driveable though.

Len - is yours a 16v or an 8v? Aren't 16vs 150hp stock anyway?
-
Yep, 16v.

Many of them horses have escaped over the years :whistle:
-
Yes 16v.
Yes some horses may well of escaped over the years.
Bought the car in Feb 2003 with 98000 miles on it.
Approx a 18 months later it went on its first RR with just a K&N filter fitted and gave 152bhp
Now with mods as stated above and 148000 miles its around 155bhp.
Just dont expect miracles!
-
All I'm saying is JKM's dyno is known as the heartbreaker, and it certainly lives up to it's expectations whenever I've attended a rolling road day there. There's always a handful that get far less than they expected.
I lost 3hp on my last one, but I know where they've gone, so for the next one (in feb, check events section if you're interested) I know where to improve in.
-
Yes but again Andres your power improvements are not just the chip!
And that is what the OP was asking about.
Agree about JKM but remember when you go there its usually cold and its darn near to sea level.
Go to another RR at say 300 feet altitude (av. for England) on a warm day and figures will be lower.
-
hmm so the first few mods on my BEAST will be bringing it back up to stock hp before i go over the epic 115hp mark!?
-
Edit. Just reread post and I'm talking crap.

This thread is about the 16v NOT 8v.

This is mine with approx 114k miles only mods enclosed airfilter with cold air feed, sports cat with cat back stainless system full service at time and apparently with a chip on but this isn't proven but going by everyone else's figures i think it might have :smiley: I think i'm going to try a custom remap in the spring running 99 ron and see what it achieves :smiley:

Doesn't seem to rev much or hold the power at the top, and curves seem a bit sharp. You can clearly see where it comes "on cam" though at about 3600rpm. I'd say it's not chipped.
Here's mine when it's healthy.

does seem a bit strange the 16v revs dying so early. least a few hundred more there!
-
Mine is limited at 7200 revs but the power drops off at approx 6600

I didn't realise it was running bad :sad: i don't really understand graphs if i'm honest what do think could be wrong ? I have noticed lately it has flat spots so was going to see if a remap can sort all this out ? considering a balanced flywheel aswell maybe that would help out also?
-

It does rev upto 7200 rpm not sure why it only went upto about 6500 tbh perhaps they didn't push it as much as they should i had just drove 2 hrs to get it done at carbon in manchester :grin:
-
Reason they only pushed it to 6500 is because it started to loose power after that, so it's pointless pushing it further.
What you want from a graph is the curves to be as smooth as possible, and for them to be on the increase for as long as possible, and on the decrease for a little as possible. Look at mine. 6500 to 7100 it's flat on the HP curve, no drop off at all which is great.
Now look at yours. 6000 it peaks and then gradually drops off until 6500, at which point the dyno operator stopped the run.
Now look at the flatter torque curve. On mine it's pretty flat all the way, yours has a spike at 3600. Mine steadily drops off from 6500 to 7100, where as yours will fall quickly from about 6000-6500, in conjunction with the HP curve.
The aim is to extend the power for as long as possible, and hold it for as long as possible, without letting it drop off.
You can smooth it out with regular services and maintenance. I change my oil and filter every 6 months/5000 miles, plugs every 8 months or so and distributor cap and rotor every year. As well as cleaning out air filter every so often along with throttle body.

Cheers mate thanks for explaining a graph :grin: I shall take a look and see if i can improve it in the spring many more things to be done to her still :smiley:
