Rotrex powered R32

What an exhaust note, absolutely stunning sound.

Lovely car! Sounds epic

[Captainawesome]

That sounds amazing!!! Off to classified to look for supercharged R32's!

[AGK]

Are you still running the original gear ratios?

[NumberoftheBeast]

Awesome project; some time and dedication (not to mention money) there.

Out of interest, what's that white 911 on your first video? That shifts.

One of those was fitted at the time. So far with all the heavy rain we have had over the last coupe of days, the shield I made seams to have helped.

Couple more videos from Vmax
First run as seen from start line http://www.youtube.com/watch?v=hxD95zCo_Uc

The run where the undertray departed http://www.youtube.com/watch?v=f7DUwVFakro&fea...

It may just be your technique, but there's a little bit of clutch slip every time you get back on the throttle after a gear change. Have you looked into that?

Beautiful car though.

Yep still using the standard gears/gearbox. Rev limiter has been raised to 7200 which helps.

Thanks, not too sure what the 911 was, couldn't catch him.

Thanks, I noticed that as well in the videos. I don't think it is slipping, more likely it's my poor technique
The ECU software does have full throttle gear change(when I remember to use it), it cuts the spark when the clutch is pressed. It can be heard at 1:05 in the exhaust video

Just asked about the 911 as with that kind of power in your car, that Porsche must be running some power too.

I enjoyed looking at your project.

Here is some of the damage caused when the undertray took off, you can see where the fixings have been torn out of the bumper.



Passenger side wheel arch liner


Passenger side engine side cover was pulled down and dragged along the track


Driver side engine cover, you can see where it has been pushed against the pulleys and belts.


The bit of aluminium at the top was fitted the day after Vmax to try and hold it together to protect the belts while I got replacement side covers.



To repair the bumper, I bought a sheet of checker plate aluminium from B&Q. I used checker plate as it was the thickest they had, strips were cut to go round the inside of the bumper on both sides.

The strips were fixed using glue and rivets.


Replacement undertray from a R32oc member.

I cleaned the old paint and rust of the metal bar, treated with rust remedy and repainted shortly afterwards it rained.


Replacement driver side engine cover.

Cut to fit around the SC and bracket, I decided to leave extra plastic to help keep it away from the belts and pulley.


When I replaced the passenger side wheel arch liner I found all this lurking behind the plastic

Didn’t get an after picture as it started raining when I cleaned it out.
The replacement passenger side engine cover was cut to fit around the oil cooler for the SC


I'm looking at getting the bottom engine cover/noise insulation from a TDI Golf to help keep the water away from the air filter and streamline the underside of the car.

There is still a little voice in the back of my head telling me to change the rods and turn the boost up

I'd think that a bigger tray would be an idea - that try looks really quite small and I'd guess the back of it flaps about a fair bit at the speeds you're doing.

[mwstewart]

This is a bit of a Golf issue. I bought my G/F a TDI and the under-tray fixings on that are also below par.

I like what you have done with the aluminium.

[crazy about cars]

Very nice sleeper! Extra points for keeping it looking as standard as possible without succumbing to the stance/dub look.

Having seen both your build threads, most things are going to look below par to you

Yep it's all a bit flimsy, especially as I have had to cut the side covers to fit around everything. It's almost like those parts of the car were never designed to cope with 170mph. An alternative to all the plastic is one of these: http://www.dieselgeek.com/MK4_Jetta_Golf_New_Beetl...
I’m not sure if it would fit mine as the SC might be in the way of some of the fixing points.

Thanks, I almost went with the “crowd” and considered fitting BBS CH’s, but decided I preferred the stock wheels. Cant “stance” it anyway, as it would never get on/off the drive.

[Blue32]

The R reached the 100k mark this week and running well.


Still really happy with it and cant think of anything else id rather change it for as it still brings a smile to my face when I put my foot down

Just about to embark on a new project, the aim is to fit a current VW RNS510 with voice control and bluetooth.

Leads to make it play nice with the stone age MKIV electronics.

Just waiting for the rain to stop and a couple of other bits, then the fun can begin.

I shall look forward to this next instalment. I'll be interested to see what approach you take with the trim; I've seen a couple of approaches so far.

Thanks, I haven't decided about the trim yet, there are two options.
1. Use the Passat sport trim as it's the same brushed aluminium effect.
2. The black plastic trim from a Caddy van.

I made a start on the RNS510 install today, started with connecting everything up to make sure it would work.
And it did, the CAN interface worked straight away, the navigation info came up on the dash display.

The only thing which didn’t work was the radio display as it should show the station at the top of the display.

On the up side the Bluetooth and voice control worked.

I found a spot for the Bluetooth microphone, I always wondered whet the little grill in the interior light was for.


It just so happens it is the correct size for the microphone.


I spent a few hours up in the man cave (aka garden shed) working on the radio cage. Had to cut quite a bit away to make it fit, and have lost the cup holders.

Just need to get some nuts and bolts to fix the RNS to the cage, if all goes well should be fitted by tomorrow afternoon

[Blue32]

The RNS510 install is now complete, I did waste a fair bit of time trying to fix the V71 motor in the climate control at the same time while the dash was in bits. The motor controls the re-circulating flap and has been making a grinding noise for a while.
It took a couple of hours to get the motor out.


Only to find the wiper arms for the position feedback were broken


I managed to find a replacement motor on EBay, so drove around for a week with the dash in bits while I waited for the motor to arrive.

Anyway onto the RNS install, had to cut a lot of the material away from the radio cage to get the RNS to fit. Before Left, after Right



All fitted


And finally back together.

Success I now have a working fully integrated RNS with Bluetooth. It sticks out a bit more than I wanted, it won't sit back any better due to the pipes for the vents and the heater matrix.

The last bit to do was the fascia trim.

I started with a Caddy fascia, as I decided the Passat sport trim would be a pain to work on as I would have to peal the aluminium off before cutting and try and get it back without splitting it


Made a template from card


Stuck the card template to the fascia and cut the excess material away.


After a bit of sanding I got it fitted, looking much better.



In a couple of weeks time the wheels are being refurbished so I decided to replace these

With these

I think they look a bit better then the old plain bolt covers

I have also had the United Motorsports haldex flash added, I think there is only 2 cars in Europe that have it so far. The flash changes the software in the Haldex controller so it engages quicker and send more power to the rear.
I don’t drive the car particularly hard, but I can feel the difference especially in the last week when it was a bit damp, just pulling a way it feels like the rear is pushing the car more. There is a lot less torque steer under hard acceleration and when having some fun on A roads it feels like the rear is pushing the car round the corners instead of the front pulling. So all in all I'm very happy with it .

[missing the VR6]

Amazing car, something like that would be my sort of dream daily driver.

Regarding the RNS510, is it 5 or 7 digit postcode finder? You probably know but if it's 5 you should be able to put the latest 7 digit dvd in and it will update the unit to 7 digit postcode finder.
