I agree with Wally on that one.1000km of racing is like 10,000+km of daily driving.The wear on the bearings,rings,etc. at high rpm and high loads for long periods of time has an effect on every engine,no matter if it´s water cooled or not.Another thing to consider is modern engines are primarily made to keep emissions,fuel economy and production costs at a minimum.In the 70´s german manufacturers used casting and forging processes that are unaffordable by todays standards,that´s one reason why the type 4 case and bottom end is so strong.As long as the temps stay "in the green",there´s no reason why Wally´s type 4 shouldn´t go the same distance as a Subaru with the same horsepower.The materials are not as different as you think,actually most modern engines use inferior metals and/or metalurgical processes to keep production costs down.

I love it!!! Well let me tell you, after all the good things that have come out of your engine storys, you are making a very good sale, so maybe you should sell something. I wouldn't have thought about doing an aircooled again until you've shared your experiences with us. Even spending more on some more sturdy parts would still net a lot of power for the money. If I ever got another car I didn't want to cut up I would seriously consider copying your setup.

Thanks again.

Very nice. What a place to take a spirited drive.

It is a beautiful track,but those looks can easily kill.It´s quite a challenge to drive at high speed and is very tricky,bumpy and slippery in places.But it is also the ultimate thrill imho,21km of pure adrenalin :D

I totally agree Mark. Did you ever drive there?
You should really ride shot-gun with me there sometime this year if/when we go again ;-)

Awesome the way that car sits.. those tires and rims look beautiful too!
Great pics too!

Wheeeeee!!!

very nice as always wally ;)
but I see you weren't running your "NEW" splitter?? on the ring...
BTW it's Sounds Soo MEAN in boost :D

Chris

Hey Chris,
The splitter is just a (very) recent development and the Ring pics were from april 16th. The 1/8 mile drag on the Assen track were from last monday ('bank holiday' over here) ;)
I _think_ it does really help. Car feels indeed more 'planted' at high speeds. The Kamai is better held in place (rock solid) by the splitter as well. Since the Kamai was probably not designed for speeds over 130 mph, if for nothing else, just the rock solid mounting of the underside of the Kamai, was worth the fitment of the splitter imo.

Last vid (promise :lmao:) from the 1/8 mile at Assen:

Yes,I´ve been on the Ring twice riding shotgun in a 911SC and drove once with a suped up Golf 1 GTI.Nothing in comparison to your ride though.So,if time permits I would be more than happy to take a ride with you on the ring!! Thanks for the offer!!:D

Well, I take it rather easy on the Ring, but driving there in a bug is much more fun :)

Yesterday I drove 325 km (200 miles) to Bitburg, ran 8 low 12-second runs and drove the 200 miles back home.
Best pass was a 12.04 at 114.8 mph, but it turned out that my clutch was slipping everytime boost came in hard...so no 11's still :(
I was very amazed the clutch holded it as long as it did, but obviously the dynorun in one single gear is a lot different then running slicks and letting the torque loose. My 60 ft times were therfore rather poor (1.9-2.0). First tun was a 1.77 but that was at a lower boost.

One of the runs (more on my y-tube account):

On the way home on an unlimited part of the german Autobahn I let the car run, trying out if the front splitter helped at all. Last high speed run was a little scary, but this time it still felt rather stable. Unfortunately a bend in the road (which was taken well over 200 km/h) and traffic made me not prolong the run. Boost was about 17 psi. Towards 5800 rpm in 5th gear the digital speedo read a max of 220 km/h (137 mph):

awesome wally - shame you didnt make the 11s though! i bet the guy in the merc was a bit suprised to see a bug fly past at nearly 140 mph :D
