Another VW gasser

<< < (2/3) > >>

Dolmetsch:

I put the crank bearing and pistons in the experimental today. Looks like it will work well.
After .008" was cleaned from the deck actual Accidental deck height is -.050"
Stock slant six is -.140" (when I say - I mean down the hole at TDC)under NHRA stock specs minimum. Production is always more. Occasionally much more. with the piston .090" higher in the bore even with the mild dish in the piston, coupled with the .100" over bore , compression ratio is smartly improved , cubes is now 237 cubic inches instead of 225. Compression is still in a range that can use good Hi test fuel. (We have 94 available here in places) Since the slant six cannot not stand too the moon RPM with its 4.12" stroke cam duration which is what determines RPM of peak power is not that high. Since duration has a large effect on Compression ratio needed (Nothing happens till the intake valve closes at the beginning of the compression stroke) The need for extreme compression in this engine is more imaginary then necessary and a build like this has good potential to be a great performer.

Dolmetsch:
Back at the Green VW.
Over the last month he took the 383 stroker short block out and did a 355 for it. At my coaching he removed a lot of the shiny stuff and made a good solid serious bracket short block. Over the weekend he took the car to the Ottawa track and came home with second place money. got treed on his last run of the day or he would have had a first. He called to tell me.  Said he is still pinching himself. Said the car was very popular at the track. We have heard from some who were there on our Ontario Rodders board. The fellow said the crowd loved the little bug gasser and he said it was just flying. He also said he had taken some phone video but didn't know how to download it to a computer. Hopefully that will happen but whatever the case Bill is about as excited as I have ever seen him.

If you can post the video if he gets it downloaded. Tell him to joint this board.

Dolmetsch:
He is not having much luck with transferring the video. He said he will find someone who can do it for him so we will just have to be patient I guess.

My friends Bill and Rita Vilneff took their VW Chev V8 powered gasser to the Ottawa ONDR race. Bill came home with a second. He had just put together a more traditional 355 short block rather then his usual 383 stroker and was trying it out. Word is it is a go.  Hardest part of running this car is putting his race face on. Says it is difficult when you are grinning from ear to ear. Crowd ie spectators love the car. So does Bill. Says it is the most fun car to run he ever had.
They gave me this photo from the Otttawa race to use. More coming. To the left you see the Hilborn injected BB Chev rail of my nemesis Pat Doornbos and you can just see the blower of Mo's Poncho rail behind the VW. I run with these guys at the great Picton Airfield races. Next one Sept 20BTW
