wasnt one for waste gate??

[Xellex]

how old is your son Wally? Is he into beetles as well, or just enjoying a good father/son say?

Great pics Wally! That´s only good that your car is so reliable,nothing boring about it! seeing the performance your motor is pumping out with that sort of reliability is a benchmark for those of us who are still building their motor.Of course each motor is different and finding the right tune,but still it proves that the type 4 engine components are extremely strong.

Great pix. Sounds like it was a great day at the track.

Yes, it still runs very well, but I really need to put some more effort into the suspension now (and maybe my driving too) as my corner speed is just too low wrt the 'competition' ;-)

My son is 14 years old now but already as tall as his mother and getting close to me already. Its amazing how fast the kids grow in this age.
He is very much into cars and almost knows more about certain marques then I do! He loves muscle cars (I'am sure you like that Mark, lol) but can very much appreciate the bug too and loves to come with me. We saw a Koenigsegg, an original GT40 and other exotic cars, which he really enjoyed and took pics from. He got a ride (I asked nicely) at the event in a '69 Camaro on a small drift course and couldn't stop smiling the rest of the day.
Kids, you can only teach them so much I guess... LOL!

He also held his camera on video mode at the roof of the pit building, but quality is...hmmm not the best. I'll try uploading the best one tonite.

Some of the other cars in my group (division Starter) on the track:

Wally the car sounds great. I am watching a couple of your youtube videos.

Cheers mate!

Hi Wally

So how did you find the LSD?

[Wally]

Found it still lying on the workbench...
Nah, haven't been able to find the time to put it in and frankly, I am still a little (lot) worried about changing diffs for the first time.
There is a last round of TimeAttack on the 25th september, but a dyno day on the 10th of september, so I need to try squeeze it in between 10 and 25 sept...
I did encounter some inside wheel spin at one point, but this large turbo spins a bit later, so I have less one-sided wheel spins out of the corner then before.
I don't drag race anymore before the diff is in OTOH as my slicks are getting worn on one wheel only, noticeably!

This is a vid from another participant on board during qualifying. Its from the warm-up lap onwards and he runs up to me after one lap while we were all still warming up our engines and tires and eventually passes me (he ran much faster lap times anyways). Very cool to see your own car from another view point.

What can I say? You´ve got a cool kid! Sounds like you two had a great day together and that´s priceless.He will soon learn the advantages of power to weight ratio It must have been very cool seeing all those exotics and also being able to flog the car on track.Go home and have a steak and a beer and call it a perfect day! Very cool and thanks for sharing!

Wally has made an appearance on the Speedhunters website!!!

Well done!

Comments can be added at the bottom so Wally, you can post some specs for the uneducated (bhp? )

[Wally]

Cool find Bruce! Thanks!
I think we better let them guess at the rest ;-)

High boost holds now (1,6 bar).
Dyno makes spool 500+ rpm later, but turbo is still too large anyways.
Still climbing too, but my nerves were only as good as 6800 rpm today at this boost :lol:

396 rear wheel Hp 8)
When calculated to CHP, that would be appr. 460 hp. It was relatively hot today though (about 28 Celcius, 80-85F).



Lower graph curves were for my reference to my 'normal' dyno I use (Superflow dyno, more high tech with controlled load) which was at wastegate boost (1.0 bar). Showed very high correlation to my normal dyno, which read 310 RWHP (this dynojet read 300 RWHP, but as said, it was a hot and humid day), so they were very close!
