Hi All,

Been looking about on the net, and notice that the 105 PD can be tuned to around 130-135bhp.

Has anyone had this done? If so, what are the noticable differences? Is there more torque? What was fuel consumption like and did anything go wrong long term?

Thanks

Craig

I got my done in December...

Once the engine gets warm the acceleration is noticably improved...MPG no adverse impact at all,getting couple more per gallon..So got a peppier car but now want more as one can have never enough of torque...

Buy a faster car?

Not trying to be unhelpful, but if you want something quicker then why start with a 105? You could spend a bunch of money on mods, none of which will help re-sale (in fact it may count against you) and pay more for your insurance as its now "modified" etc. In the long run isn't it just easier to trade for a quicker car?

There are lots of reasons to tune a PD105 rather than trade in for a faster car:

• Better economy and reliability than a PD or CR 140/170
  
• Not taking the risk of buying another car with an unknown history
  
• Cost (cost to change versus remap cost)
  
• Power delivery of the 1.9 engine (some people love it!)
  

In fact all of the above are why I've signed up for the Shark performance remap + STS group buy!

I have come to the same conclusion....

My appetite for quick acceleration has gone up...after stage 1

To get say upto 200 HP or possibly more some one suggested this on TDI forum...Can not even get it for 2000 quid and the hit on insurance will be ?????? so will probably go in for 2.0 CR VRS when the wallet permits...

Well for a start I've just bought the car and was mulling over some 'mods' to it like cruise control and spottted on Shark Peformance as remap to 135bhp and started looking into it.

Also I love the car I have, I like the power delivery and the economy and its in excellent condition. Also sod the resale value, I intend to keep this car as long as possible too.

Finally, you could say that about anything really, why get coil overs on a vRS? Why remap one? Its easier said than done to get a 'better' car.

Also thanks guys for those that have responded with good advice.

Hi,

I know my replay is late but maybe some people would be interested how much power they can get out of their PD105 engines. Here is a RR printout which has been done after GT1749vc hybrid turbo has been installed and remap. No other modes affecting power. Not so bad I would say

 

 

175bhp/400Nm

Shark did mine.  Basic stage 1. 

At normal pootling speeds, it feels much the same.  If anything the economy has improved.  Once past 1500 rpm it takes off, so acceleration is hugely better.  Only problem is now 90+ comes up very rapidly.  But that only improves overtaking, Officer - less exposure on wrong side of the road.

They also blanked off the EGR.

Shark quoted 150bhp with a remap to me.

 

Also seen this figure around the internet too. 135bhp sounds like a fairly onservative map but still about the same as a standard PD130.

I didn't ask about any numbers, as it was the on road performance I was interested in, and as it happens. entirely satisfied with.

As a previous poster mentioned, if you want performance, swop for a vRS.

Agreed. Fine if you just want to get out what the engine is capable of but don't expect it to be a fast car.

 

Still tempted by a Shark STS. The car performs ok as it is and definitely helped by the DSG but just now and then feels like it needs a little more oomph (car full up 20-25% inclines the other week springs to mind).

Who are you guys insuring your mapped 105 Pds with? I want mine done but all the quotes are in the £350-450 bracket. I'm paying £200 at the moment.

I could insure an M3 for £450 and my 232bhp Z4 is £340.

hmm I'm with Adrian Flux it cost me like £550 for fully comp with EU breakdown cover and 4 years no claim discount but I've got uprated brakes as well, turbo, uprated suspension etc.

Mine was remapped to 147 bhp (Measured on a rolling road). Because it was a custom map, the guy doing the tuning was able to take the edge off the massive surge the unmapped engine gives at 2000ish rpm and get it to pull well all the way to the red line. The remapped engine pulls harder at all revs, but delivers it much more smoothly.

Before the remap it was pretty much impossible to keep the engine under 40 mpg on normal roads no matter how hard I drove once the engine was at temperature (I wouldn't recommend giving it full throttle before the oil is at temperature remapped or not). Now it's possible to get it under 40 driving hard, but when I drive for economy I get a few mpg extra over the unmapped engine too thanks to being able to hold 5th gear for longer, down to 25 mph if you let it coast along on very very light throttle. A 6 speed gearbox would make it better again though as it has more than enough power to pull a 6th gear now.

Incidentally the guy who did my remap was driving a PD105 VW Caddy DSG, completely stock engine but mapped to 170 bhp, but wouldn't recommend the higher torque he was getting (I've got about 320 Nm with the remap I have, he had more) for the 5 speed gearbox or for any engine that can't be plugged into diagnostics as soon as any warning pops up. I've had over 3 years and something in the region of 40 - 45,000 miles of trouble free driving on the remap so far.

After explaining what I had done to the car to my insurer I got it insured as a PD130 engine (One guy at an insurance company I phoned told me a remap didn't qualify as a modification as nothing had been physically altered, but this is very unlikely to be the company's actual opinion on it). I don't think the insurers should have any cause for concern unless the power of the car is way outside the range the chassis is designed for, but being honest with them is the best way to avoid them weaseling out of covering you if anything does happen. It cost the same to insure as the unmapped car.

The before and after torque graphs almost mirror each other .

However,the power graph for the remapped  scale keeps on rising to around 4000rpm.

Is the power figure a bit optimistic?

not sure what exactly do you mean by that? the before graph is on some generic map I've paid £60 for as I couldn't stand the stock power... and what you see is the difference between stock turbo and generic map and hybrid turbo and custom map...

What does this tuning modification do to the top speed of a vehicle with this engine, out of interest?

 

I've got the aforementioned TDI 105 in my Fabia, so the stock performance will be much the same.

 

But is the top speed at stock due to hitting the rev limiter in 5th gear, or because wind resistance overcomes engine power?

 

Bearing in mind that as far as I'm aware, this engine is almost invariably married up to a 5-speed, not a 6-speed manual gearbox.

 

I've never driven anything like as fast as that, and nor do I expect that I ever will, so I can see no other way of finding out!

The top speed is governed by air resistance etc overcoming the engine power.

 

Top speed could theoretically be increased with a remap if the car has more power so would be able to push through the air at a higher speed.

 

The only two transmissions available with this engine are the 5-spd manual or the 6-spd DSG. Gearing in top gear isn't too different I don't think (2100rpm at 70mph?).

 

The only place I have ever reached top speed in any car is on the Autobahn. Holding the throttle to the floor it stayed in 5th for ages and then finally changed to 6th at about 115mph.

My Octavia 4x4 came with stock 6 speed gearbox but it was a little bit to short for me especially that I was initially aiming for 250bhp which due to some complications will have to wait until next year..., so I've installed JLY transmission from Audi A3 Quattro which is a fair bit longer. Anyway - 6th gear at 3000rmps I have nearly 100mph on the clock (149km/h according to my satnav) I could easily go up to 4000 rpms the power would still be sufficient but since in the UK it's a bit risky (ban, jail, fines etc..) and when driving through Germany I had my wife sittting beside me (I won't be quoting here opinion about me driving over 90mph...) I haven't had a chance to really get too the top speed ;/

Forgot the 4x4 1.9 came with a manual 6spd. What was the gearing like? Was it actually quite similar to the 5spd but just more ratios crammed in to help with the 4x4 aspect?

 

Sounds similar gearing to my old Cordoba PD130. 70mph was 1700rpm.

 

Allowed me to get it up to a top-speed (gps) of 138mph on the Autobahn which I didn't think was too shabby.

very short 1st gear then the rest I would say a little bit shorter than in my Octavia mk1 5speed with EGR gearbox and the 6th gear a little bit longer than the 5th but just a little but for 105bhp it was ok I guess especially with the weight of 1618kg it was a donkey...

Agree totally. 1st gear fustratingly short in normal driving, execellent for crawling or towing though. 2-5 all shorter than the 5 speed with 6th a bit taller than 5th on the 5 speed. I find 6th pretty flat. I expect the 4x4 ratios are pretty similar to the DSG 6 speeder maybe?

Sounds like it.

 

It changes out of 1st gear almost instantly when setting off steadily.

 

It then only really uses 1st to crawl in traffic on tickover. If you use any throttle while creeping it goes straight second.

 

Not sure about 6th gear though. What RPM does 70mph give on the 5 speed box?

extra insurance is hardly a deal breaker, my insurance went up £18 when i fitted a dtuk box to my car.

You are lucky. If mine went up only £18 for a tuning box/map then I would have mapped it the day I bought it

 

Phil, I think it turn nearer 2400 at a true 70 in 6th (About 74 on the speedo) so a fair bit shorter than the DSG. I find 5th perfect for towing on the open road being about in the middle of 4th and 5th on my MK1 110 tdi. 6th for towing is ok downhill! lol
