- In this video I install the Blow Off Valve on the supercharged 1968cc motor. I show how the vacuum line fitting had to be adjusted, and start the motor. It idles smoothly!
G'day,
You have arrived at the exciting stage, the test drive.
Don't forget the camera.
✌️ Peace from Melbourne Australia.
Thanks - yeah getting close. But the AF ratio drops down to 9 now when I rev. So I think I may need to swap in the smaller 1.45 main jets or smaller. I think maybe the turbo emulsion tubes plus the 1.55 main just (or 1.5 - I forget which ones I left in there) riches it up too much under boost when revving….
Nice one, can’t wait to see the test run video.👍
Yeah, so last run the AF ratio was going down to 9 when revving - with a little black smoke. I think I’ll swap back in the 1.45 main jets and re-measure….
Man that engine is starting to look like a beast!! So how many HP. You think you added to your beetle by now? Nicely done!👌😎👍 looking forward to see the test drive!
I am so close. I have been risk averse to driving it, because I have less visibility on what is going on. In my garage with all the gauges I can control everything if something seems off....
If you go with original oil filler setup,it might have more room for the blow off valve.
My cousin informed me I can remove the blow off valve cap and rotate it 90 degrees and then the barb wouldn’t interfere with the oil filler. Why didn’t I realize that myself!!!
Are you going to upgrade the ignition system?
No plans to do that yet - do you think that is absolutely necessary for supercharging, or can I just retard it by 4-5 degrees and leave electronic ignition in place?
@@LarsonSplitBus- What do the guys on samba recommend?
Clever, I'm always looking for a different way that may upset the purists.
There is nothing pure about this 1961 VW Beetle. It has a 1968cc supercharged motor, and it is on a 1965 chassis - since that is the chassis I could get with a title. However, it is a fabulous car!
@LarsonSplitBus- Yeah, I dig it. I built that same engine for my 64 baja. It's a blast in the mountains.
