Upon request, an excuse to post some pics and specs of my car: a 1303 superbeetle from 12-1974 (model-year '75)

In 2007 with the 2,7ltr (103x80) type 4 engine on a track day:

Beetspeed - June 1st, 2009 at 07:35 PM

Hey Steve, yes that the Nurburgring/Nordschleife.

i dont think iv ever seen a car like your 412s

looks awesome!

Well done to owning two beautiful cars!!!


debiasi4 - June 3rd, 2009 at 08:57 AM

great looking car - would like to see pics of your oil system plumbing and tank setup- also why did you go with a smaller crank with the turbo engine
thanks adam deb


66deluxe - June 3rd, 2009 at 10:46 AM

Wally went with the 66 stroke due to the cylinders he had, they are original oettinger nikasyls which suffered a rod failure in a larger N/A 2.7 he was able to salvage the cylinders buy shortening them hence the use of the 66mm stroke.


Beetspeed - June 3rd, 2009 at 04:18 PM

I couldn't have explained it any better myself Damon ;-)

Also the 2,7 ltr heads (unwelded 914 2.0 units with 46x40 valves) have been refurbished, even though a piston hit it at 6K rpm.
Still, a lot of new parts/methods have been used and so far it works very well.
The 66 stroke stock 1700 crank has no counterweighs and runs cleanly to 7K rpm. Its a VERY strong crank with big main-rod journal overlap also due to the original 55mm rod journals.
We used extremely light JE custom boxed pistons with a VERY high piston pin location and 19mm pin diameter to accomplish this.
Rods are lightenend original type 4 ones with ARP bolts.
Lightweight tool steel type 1 lifters were used that are DLC coated, as well are the piston pins and rocker shafts.

Here's a pic of the DS tank location:

Oil routing is very simple: one oil line (the bottom one has been replaced last year bij a -12 AN braided line) from DS tank to dry-sump oil pump (feed), one line from pump to front mounted oil cooler and back into tank (scavange line), thats it. The inline cut-off has been removed as well as I was afraid I might forget it some day...and drain back is not that much and balances out over a long period of time.

Love your work Beetspeed. Vid of dusting the angry rice burner is priceless.
What cam in your 412 engine. I have a similiar 914 engine efi 4x 40mm TB, 7.5:1 CR and 94 rwhp with std heads and k8 cam.


Beetspeed - June 7th, 2009 at 02:46 AM

Thanks Mat,

The cam in the 412 is the bone stock 914 2.0 cam. It has stock intake runners with a single Ford (escort) TB and Golf G60 injectors. Stock heat exchangers and exhaust.
Max hp was at 5150 rpm. I think leaving the stock head sealing rings out and thus raising CR and induce better squish made the difference.

Oh yeah, the rices had launch control, supercharger AND NOS, (about 400 hp), super soft slicks at 10 psi on the front. It did him no good :lol:

Greets,
Walter
