Yeah, allthough visually it doesn't really looks to be any smaller...:

Didn't take more than a hour to exchange them :)
New feed pump (Carter 100gallon/h) also installed.
Attending a dyno day on the 12th march, so fingers crossed it now all works..

Man....we have to wait almost 2 weeks? That sucks :D LOL! If the trend keeps going as it has in the past,this change should also bring up another 50HP at the same boost level? Im sure you will pass the 450HP line...

Ultra cool.

Wally March 2nd 2011 15:04

Just went for some better fuel just across the border today and had the opportunity to tune the maps again and check out the new feed pump, higher fuel pressure setting and the other turbine housing.
All worked VERY well :D
Boost threshold for my own 1 bar boost reference went down 300rpm to about 4030 rpm :)
Boost and fuel was also very stable so tuning was much more easy.
All set for dyno day :cool:

Wally, a quick question: Are you using the stock beetle voltage regulator or the riechert (porsche) one? I'm trying to build a 1.7 type4 for this season, and I was wondering if I could just use the stock regulator, in it's original position, and wire the porsche alternator just like the orig. vw one was.

Wally March 6th 2011 06:25

What regulator is a topic on its own. Get the right one, type4's also work, but not always as good as could be. I use an electronic one.

Anyways,
Got my pics from Julian today Yeah!:

yeah, you're right.. I was just feeling a bit lazy, and wanted to leave all the wiring alone. But I'll use the regulator that came with the riechert kit.
Oh, and great pics!!!

Type 4 2056cc 44x38, Web86, Remmele exhaust, DTA E48.
Stock gearbox, which then of course broke on the line at Santa Pod on the 2nd run after some expert advice on how to launch from 'some' DKR member :lmao:
Car is very, very nicely done, much nicer then mine and is very light and very good roadholding (I drove it last year).\

BTW, I have bought a piece of (cage) pipe to re-stiffen the right-hand side gearbox fork after I needed to remove one leg of the Cup-strebe because of the turbo's 4" air intake piping..

amazing!!!!!!!!


what are the dimensions of the wheels?

Wally March 7th 2011 11:38

On my car, on drag race set-up as seen above (black wheels), the fronts rims are 3,5x17 size and rears are 7,5x15 iirc.

ferfre007 March 7th 2011 12:18

I understand, these wheels are safe with the car super lightweight

excuse my English, just use the translator hehe!

No, not safe for normal use on the road, ONLY for dragracing!!
The gold centered wheels are for the road and circuit (18")

The car is super heavy by the way, not lightweight at all ;)

Wally March 9th 2011 17:30

Got bored today and downloaded the log from the 1,8 bar (1,8-1,9 ~26.5-28 psi actually) boost 'mishap':
Apperently the alu cylinders can survive this boost! Who would have thought that?

70Turbobug March 10th 2011 06:52

Cool! Am I reading this correctly? 4703rpm and the throttleposition is WOT / 100%? The other 2 graphs are going downwards after that except the throttle-it remained opened? Sorry...Im still learning how to read these things.Or ist that just what the peak was?
