I think it was featured in VWMA a while back.
Although it was only a N/A 1915 back then.
Hope he did not go to the dark side(Japan).

Hi Everyone,
The car went on the track for the first time with the turbo on Friday at Oran Park GP circuit. Rudi did 2 sessions, while I was there, around 10
minutes each without any hiccups.
That's a huge achievement because the turbo conversion is extremely complex, Rudi couldn't test the car on the street and race tracks are good for
bringing out weaknesses.
IT'S STILL A VW!
I'll guess the specs from what I've heard and seen. The amount of work that has gone into this engine is amazing. Hopefully Rudi won't mind me
spilling the beans and maybe he'll elaborate further:
- DMS crank somewhere around 72mm stroke.
- 92mm slugs & jugs
- Porsche fan
- Cut down intercooler from a Japanese car
- twin carb-style efi throttle bodies
- A brilliantly adapted cold air box from a modern car
The old 1916 had over 110 RWHP and the new combo doubles that on conservative boost using pump fuel. Now consider that it is engineered to kept cool
in circuit racing conditions and not just for a quick pass down a dragstrip!!!!
Hats off to Rudi and his helpers for their engineering skill and for being more than a bit bonkers! There's probably a smiley face to emphasize that,
but I think smiley faces are stupid  !

.thanks for the kind words guys ,heres a few details to wet your appettites , the engine ran very well on a fat tune 120c oil temps max ,didnt know
how the new set up would disperse the heat as this set up was untried, rx3 oil cooler with fzr elect fan to cool engine oil while not racing worked
great car also runs water cooled garret turbo off 200sx with fzr yamaha radiator and fann trigered through e8 haltech computer cars booked in for a
tune to trimm the bottom off as it is not running hot at all.still plenty of work to do to sort brakes and brake ballance see smoke on 1st post, car
is awsome to drive bringing a smile to the dial as soon as you push the loud pedal delivery is smooth and controled, power slides out of corners ,no
problems at all but no mashing of the pedal the sucker just wants to do donuts. im still trying get the smile of my face, maybe all those hours i put
into this setup was worth it also thanks to john ladimatos, jeff dunn sorry about bulldozing with the new air dam you built,and john molner for
helping us out on the day . drive it right at the right place on the track cheers Rudi

Hi
Good on you Rudi, cant wait to see the faces on the other competitors when they see you have a hair dryer on the bug.
Those camera angles make Oran Park look really different, I didn't recognise it.

Hi Rudi,
Love the HP figure, but the highest points are all under 5500 rpm  I thought you said that you rev the tits off this thing 
Good to see that CT is still supportive of you, even though he may be your competition.
Rudi, you also recently took me for a drive in your convertible, whats the chance of a run in this one. Oops, forgot it's not registered. I would
probably shit myself anyway, I'm not a good passenger.
Keep up the good work and more photos please and one of the engine if you will reveal.
Cheers, Kevin

Very nice! 
What category do you compete in Rudi?
I'm planning to make it to Wakefield in May, will you be running the car there? Would be great to see all you NSW guys on track in the flesh, I've
been seeing all these photos for too many years now.

generally the rules calculate displacement* some constant to account for the forced induction i.e. 2l*1.5=3L

I am fairly certain that the CAMS multiplier is 1.7.
It certainly is that for Group 3 cars (IMP)
Makes it a bit of a hard one because even a 1776 turbo will put you in the 3l and over class.
So Rudi has a 1915 * 1.7 = 3255.5cc
Crazy eh?

e8 haltech took place of the f9 because required ignition and boost control both computers ran same hp when it was natualy aspirated but i had to
graph the dizzy to suit .e8 gives alot more optionsand adjustments on individual cylinders ignition and injection also data logging agreat set up 3.5
hrs to set up from scratch unit can also store several tunes im running 4ls1 coil packs with bosch dual pickup dizzy you can still buy e8s set and
forget

first round of nsw super sprint championship car ran 1m 23s oran park gp lost 2nd gear on first warm up lap ran the whole day in 3rd and fourth a lot
of turbo lag in third gear instead of second car ran well all day oil temps didnt run past 110c even after a double heat, porsche fan conversion is
working better than i expected,more boost wont cause too many heating dramas,the new rear wing and front air dam built by jeff dunn worked well with
excelent hispeed stability after dropping the rear torsion bar height on the day no bulldozing sand traps on the day,brakes still need a bit of
sorting .well its back into the garage to pull the box and strip thanks again to jeff john boris for helping out ceers rudi

Apart from the gearbox woes it sounds like it was a good first race meeting for the new setup.

It was good to watch rudi drove the nuts off the car and with the problem gearbox rudi was still very quick everywhere but lost a lot of speed in the
slow corners. I think rudi has run a 1.20 at Oran Park with his old non turbo motor so a sub 1.20 will be on the cards when it is all sorted. Had a
great day with only one angry shoot fired.:

Well done Rudi ,
i was with the subaru crew next to you, see you at the next meet at Oran park in April... shame about the gearbox with second gear, can't wait to see
the beast with the extra " BOOST".
Loved the car,,,, " FLAT FOUR POWER ".

finally pulled the box out phew what a job a lot more components to remove than a 1916 with webbers . striped the box down , no gear damage, excess
movment at output shaft replaced spacer washer with 15 thou thicker one,fitted genuine sincro ring all nice and snug again ,ceramic coated the turbo
exaust housing found the internal waste gate was bleeding off exaust gases made new adjustable bracket ,retuned car now running 209bhp atw on 14lbs
boost plenty of potential left in the set up yet as engine temps at 110c after 12 consecutive laps mean there is more boost coming.no idling the car
around pits for 10 minutes cooling turbos and engines pull into pits turn it off let the fzr fan and radiator cool the turbo housingasthe engine is
not hot at all, this set up working really well so far.porsche fan is an absolute must have,should have fitted one years ago ,thanks to boris at
vintage for your advice and support .oh well its back to the garage cheers rudi
