Question! Lets say you have a 57 Oval with the Okrasa kit, and you want to add gauges, shocks, and other speed goodies, what was on the market at that time? Were the 356 wheels the ones to run at that time?

I don't think the 356 wheels, by themselves, would be considered an old speed goodie, but, if you had the 356 Porsche aluminum brakes to go along with those wheels, then they would.

Vintage Speed to me is finding a 1964 Ghia Coupe in a barn with 22k original miles and wanting to maintain the original spirit of the car while being able to keep up with modern day cars. It is the fun of (ok frustration at some points) finding the old go fast parts and building it up. I did a full exterior restoration (interior is factory fresh) and added vintage/old school parts to fulfill my dream of driving a fairly fast, really cool, somewhat economical car that gets comments everywhere I go. My wife checks every note that gets left under the wiper. The wheels (the 356b brakes are behind them) are 70ish along with the EMPI steering wheel and Hurst shifter, but I think the spirit is there. I drive it everyday the weather permits with no regard to the miles I am racking up on what could have easily been put in a museum somewhere. While I can not explain it, it is therapy for preparing me for the long work day and relaxes me on the way home. Yes, I still have all the original factory parts down to the original tires in proper storage.

Nice Ghia I would like to add pieces that would have been available in 56-58? I am not talking so much about the Okrasa, or Judson applications, but other parts like gauges, shocks, wheels etc!

I think modern cars don't give the driving experience as the older (70's and older) do. New cars are so far removed from the road with anti lock, anti slip, stability control, adaptive power steering, power assisted brakes, climate control need I go on? I have a Passat and I can throw is around the road and it will do its best to keep things settled: it's a comfortable easy drive, but it lacks that smell, sound and skill required to drive the Beetle (at I'll bet at a slower speed), with some spirit, but only occasionly at weekends when it can be enjoyed for what it is. This is my opinion as I enjoy the driving experience and I love the Beetle; simple German engineering that works.

I've only seen these more as curiosities than a true performance item, until I understood how they work. I've never used one, I have no first-hand experience. (looked at one at a swap meet once) But I understand the theory.

The idea is to add an air 'bypass' if you will, around the carburetor throttle blade, such that more air is available to the engine. The kit includes a secondary valve that is connected to the stock carb's throttle linkage, so that as the carb throttle is opened, the supplied secondary valve, part of the kit, opens as well, allowing air to flow through the rubber hoses, and into the intake tract. That extra air is being introduced vis the sandwich plates, also part of the kit, that are mounted between the stock intake manifold and the head. Pretty cleaver idea, no machine work required, you retqin the stock carb (although you would need to re-jet it to compensate for the additional air). The key is to adjust it so that the secondary valve is completely closed at idle, as to not ruin idle circuit metering and mixture, and to open at some point during throttle opening, and stay open (like a valve on a woodwind musical instrument).

Assume for a moment that the 28mm choke of the carburetor is a restriction to the intake tract at higher rpm (which BTW, I think is a pretty safe bet). You can't afford an Okrasa dual port kit back in the day, or even know where to get one, and don't want to take your new engine apart anyhow. No one makes a complete dual carb kit for your stock 36hp, which is what you might need (if you could get a decent dual carb throttle linkage, which were mostly crap back then) But you know if you could just get a little more air into the intake tract, you could increase the size of the main jet to compensate, and would make a little more power from the stock 36er. They likely sold for less than $60 back then.

If you have ever read anything about NASCAR crew chiefs cheating with restrictor plate engines, you have read about (illegal) hollowed out carb mounting studs, passages milled/drilled under the manifold vented to atmosphere, all sorts of ways to get just a little more air past the choke point of the carb and restrictor plate.

I think it would be fun to mess around with one, but I wouldn't expect much return on investment.

i put an nos one on my 55 deluxe bus. all i can say it did something . how much i don't know? not much but i could feel a little more mid and top but not much. it's hard to tell with a heavy bus? should of kept it in the box for a conversation piece. going w/w okrasa stroker! and going to put it back in the box. maybe i will do a dyno run with it on and with it off and see if it really does anything?
