GUEST BLOG - Pinderwagen - Track Spec Golf with a Difference

We are please to welcome Nigel as our Guest Blogger.

His Golf is one with a serious difference, and laps the Nurburg Ring in under 8 minutes.

For those of you who have been to the Nurburg Ring, you will have probably seen him there, he is certainly known to a good number of people...

He puts together in some amazing detail every blog he does. Well worth a read

READ the Pinderwagen blog




What is the Pinderwagen ?

After a smash at the Nurburg Ring, Nigel has spent the last 10 years continually modifying the Golf from a pretty standard MK2 with a 2.0 16V engine from the MK3 Golf GTi, adding Megasquirt and GSXR 750 Throttle bodies and then the Turbo back in 2014.



We’ll let you know every time a new update comes along...

Hi All,

New Blog post added. Very interesting, all about Roll Centre correction, for all those of you whop are interested in professional set up on your car.
Nigel talks about how he has looked in detail on his Golf.

What is Roll Centre ?

The Roll Centre of a vehicle has a large impact on handling but it`s something not many people fully understand.

A “roll center” (RC) is a theoretical point around which the chassis rolls when cornering and is determined by the design of the suspension. - That`s all well and good but it obviously goes out of the window as soon as the car is actually moving on circuit ! For the purposes of this post the calculations and reasoning are valid.

I know there are chassis engineers who will point out I don`t mention the Centre Of Mass, you are correct, I don`t ! lol Whilst that is obviously highly relevant, this post is only about the effect of balljoint extenders on the Roll Centre.

NEW UPDATE :)

Engine strip, inspect and rebuild

My Golf had zero engine issues on the last outing at DN in May. The wastegate broke as I`ve explained elsewhere but that was all.

Upon returning to the UK I fixed the wastegate and at the same time checked the condition of the piston crowns using a boroscope Matt bought me for my birthday. All 4 had no damage whatsoever, I was just checking to make see how good the camera was not because I thought anything was wrong.

I was at CoventryMotofest the other weekend, unloaded the car and left it idling for 10 minutes or so as usual. Went out for the `parade / sighting` laps with Cat in the passenger seat.

First lap was really steady, following the car ahead and just seeing where the road went.

After around 20 seconds into the 2nd lap I said to Cat "It`s really strange driving without a helmet at low speed, I`m hearing noises I never usually hear. I never knew the engine sounded this tappety, it`s surprising how much the helmet muffles that"

10 seconds after that it made ever more tappety noises and just stopped

I had taken no tools with me at all so was unable to perform any diagnosis over the weekend but I said to several people it sounded like a valve/top end issue.

I have a cheap USB boroscope that connects to the camera and that clearly showed some marking to the piston crown.

He's been out again, at Cadwell this time :)

Read the full artile on our blog PINDERWAGEN - Cadwell Park 4th July 2017





He had a little bit of an off !

The pedal was higher than usual and I had to adjust my foot to press it. Once I had lifted my foot enough I pressed the pedal but it didn`t move. I had to press REALLY hard to get it to move but that locked up the wheels. The pedal then felt the same as usual and I was able to cadence brake whilst going towards the grass. I applied left hand lock and by coming on and off the brakes I was able to turn the car on the grass and rejoin at the top of the mountain.

Videos on the article too ! :)

He's been at it again ! This time back to the Nurburg Ring, to Ringmeisters Prime.

Ringmeisters Prime. What`s all that about then ?

I've done quite a few Destination Nurburgrin events over the last several years and I`ve always found them pretty quiet with as much free lapping as I ever wanted. After a stoppage you may get a bit of a rush from a lot of drivers to get back on track but otherwise you cproperan drive straight out of the carpark and onto the circuit without ever having to queue.

Darren has still had a lot of requests for even quieter days from many drivers so he thought he would put on a day with significantly reduced cars allowed on the event. This did mean the price had to increase to cover the circuit rental and whilst it was a fair bit more than a standard DN Event, it was still cheaper than the Grand Tourismo event a few weeks earlier and that had another 20 cars booked on.





How is this for a Tyre issue !!

As soon as the front passenger wheel was removed, the problem was pretty damn obvious I`ve heard of tyres blistering but I`ve never seen anything like this before. I reckon I need to get a T shirt made with the phrase "I`ve never seen that before". It would sum up the weird issues I seem to get on these events.

The blister was like a soft balloon and everyone who saw it couldn`t resist poking it and telling me they hadn`t seen a tyre do that before. I have spoken to Toyo and am going to be sending it back for them to inspect and hopefully shed some light on why it failed because right now I have no idea..

Next edition ! :)

Nigel adds an Engine Breather and Catch tank set up to the Pinderwagen - Read the full Blog

When converting the standard 2.0 16V engine to run a Turbo they often `breathe` quite a bit of oil from the rocker cover. There is no OEM rocker cover breather and this can often cause issues.

A friend had already fitted this mod on his, but fortunately, he was able to get the same modification to a Rocker cover done for me. He knows someone who was able to do the Aluminium welding and machining. First off, mill off the stock ridges
