Hello Corvair Friends!
I hope that this message greets you doing well.  I just wanted to send out one final reminder about our Corvair Track Classic in Hastings, Nebraska this August 28-30.  As many of you know, we will have two days of racing (Road racing, drag/"grudge" racing and Autocross…..see attachment for complete schedule, etc.) plus a BBQ and car show.  The event is open to ALL Corvair drivers (not just racers!) and is a timed competitive event by classes.  
Thank you to those of you who have registered, I appreciate your support!   If you are still "on the fence" about coming, I would be grateful for you consideration.  I am confident everyone is in for a great time with Corvair friends on a World-Class track!  Please don't hesitate to call me with any questions. Thank you and I hope to see you in a few weeks.
Blessings,

     Creativity is great and I encourage it. Just saying, this company has spent decades perfecting the best air cooled automotive cylinder head ever made. Why not use these?

Funny to see these 100+ mm air cooled cylinder heads on this site... Those are single overhead cam pieces and not really the good ones... I'm not going to knock the drawings I've seem... There is a lot of time and creative thinking going on there... I've enjoyed seeing some different ideas in these designs... Yes, there are some draw backs to the old Corvair head design of 1950's but, they're still pretty cool... 

Overhead cam designs for air-cooleds are both complex and get heavy with all the extra parts you need to make it work... The heads become more complex with port and valve angle just to cool them... I've attached a couple pic of what bare DOHC air cooled racing heads looks like... So, I say design away at those Corvair SOHC and the DOHC ideas... I've been on the other side and those push rods looks like fun to me...

Thanks

     Makes sense on one level, but buckets more cash can be saved by simply transplanting a 911 engine. But then, we are getting into Corv8 territory and I personally am more partial to GM products. Some of our member have rear mounted SBCs and I think Mike as a beautiful rear mounted LS.
I think love of the old Vair flat 6 has to be its own reward. Power is limited.

Funny to see these 100+ mm air cooled cylinder heads on this site... Those are single overhead cam pieces and not really the good ones... I'm not going to knock the drawings I've seem... There is a lot of time and creative thinking going on there... I've enjoyed seeing some different ideas in these designs... Yes, there are some draw backs to the old Corvair head design of 1950's but, they're still pretty cool... 

Overhead cam designs for air-cooleds are both complex and get heavy with all the extra parts you need to make it work... The heads become more complex with port and valve angle just to cool them... I've attached a couple pic of what bare DOHC air cooled racing heads looks like... So, I say design away at those Corvair SOHC and the DOHC ideas... I've been on the other side and those push rods looks like fun to me...

     I guess I have been spoiled, both by much more powerful cars, including a Corvair with over 15 PSI boost. <G>
And yeah, the 911 engine, overall, is simply got more engineering in it.

     If you are familiar with the overall costs and R&D of bringing a project like this to fruition John R. is absolutely on point here.

     Subaru John,What do you know about the engine from an SVX?   Just found out a little from on-line sources:  six cylinder called an EG33 with 3.3 litres.  Saw one in a Pick-a-Part recently, wondered about the engine dimensions.  Could the upper intake plenum and throttle body be easily mated to Corvair heads already set up for Webers?   Apologies if this has already been discussed.Scott

     If anyone is serious about a new Corvair head, and can get all the
engineering done, I bet I could get you a real deal on production.
Probably be able to get the first heads to roll out of the foundry on their
way to CNC for under $150,000. And that is CHEAP! USA castings. I really
think all this energy would be better spent modifying existing heads to
make more power.

     Alas, no. Air cooled engines have a significantly larger bore to bore spacing than their water cooled counterparts. As such, the manifold will be too short. Also the EG33 has no carb manifolds available for it. 
Now, if you wanted to use the whole engine....

Subaru John, 

 What do you know about the engine from an SVX? Just found out a little from on-line sources: six cylinder called an EG33 with 3.3 litres. Saw one in a Pick-a-Part recently, wondered about the engine dimensions. Could the upper intake plenum and throttle body be easily mated to Corvair heads already set up for Webers? Apologies if this has already been discussed.

     Ayep. Or using the 'other' air cooled heads. Heck, they're hemis! Just make the right valve gear for pushrods, and away you go! 
 And yes, the development alone would make new heads cost prohibitive. You KNOW the first ones won't be right.

There is a lot of time and creative thinking going on there... I've enjoyed seeing some different ideas in these designs... Yes, there are some draw backs to the old Corvair head design of 1950's but, they're still pretty cool...

     What's so wrong with the Corvair 140 head that a good cylinder head guy can't fix? How about modern valves with smaller dia. stems as a starter then proper valve springs with TI  retainers... You want the heads to flow then think of a proper exhaust this could work wonders... It's funny how no one has said anything about the1950's  intake and exhaust design problems... The Corvair engine was pretty radical for it's time but, that was early to mid 1950's... Sadly we didn't get the factory muscle car engineering of the mid 60's in the Corvair but, we still have a pretty cool piece of early 6 cylinder air-cooled technology...  If you really want the Corvair engine to work more efficiently then think of what modern technologies that can be used... Think of them as advantages not the opposite ,using what is already available can make for greatest most dependable power for the dollar... Sometimes it's the little things that keep being over looked that can be the real performance enhancers... I know that we've all become part of a society of off-the-shelf or it doesn't exist... Unfortunately to make things happen you need to be a little or a lot outside the box when it comes to making things perform more efficiently... Making raw power is easy but, making it last is an art...

     My biggest issue is cooling. Therein lies all the issues. Making big power is pretty straightforward. Keeping it cool, that's an entirely different matter.

What's so wrong with the Corvair 140 head that a good cylinder head guy can't fix? How about modern valves with smaller dia. stems as a starter then proper valve springs with TI retainers...

Sadly we didn't get the factory muscle car engineering of the mid 60's in the Corvair but, we still have a pretty cool piece of early 6 cylinder air-cooled technology... 

If you really want the Corvair engine to work more efficiently then think of what modern technologies that can be used...

     I've seen a lot of chat about using these SPECIAL heads.What I haven't seen 
 are images of them installed in a 'Vair or descriptions of what was needed 
to get the job done.

Funny to see these 100+ mm air cooled cylinder heads on this site... Those 
are single overhead cam pieces and not really the good ones... I'm not 
going to knock the drawings I've seem... There is a lot of time and creative 
thinking going on there... I've enjoyed seeing some different ideas in these 
designs... Yes, there are some draw backs to the old Corvair head design 
of 1950's but, they're still pretty cool... 
Overhead cam designs for air-cooleds are both complex and get heavy with 
all the extra parts you need to make it work... The heads become more 
complex with port and valve angle just to cool them... I've attached a couple pic 
of what bare DOHC air cooled racing heads looks like... So, I say design 
away at those Corvair SOHC and the DOHC ideas... I've been on the other side 
and those push rods looks like fun to me...
Thanks

     Take a good look at the DOHC drawings. They are pent-roof with 4 
valves/cytlinder using replacement parts for a 16-valve Ford Fusion engine.

     Another approach might be to supply power to the ignition through a relay, then the engine compartment kill switch would break the relay trigger to kill the engine. Might not be a bad way to go if you havea lot of extra electrical stuff powered up (safeguard, electric fuel pump, other computers...) that could be fed off of that relay when the engine is running.Kevin

 Subject: [fastvair] Electronic distributor kill switch

  In years past, I installed a small chassis box on the engine "firewall" with a toggle switch to power the ignition and a push button to crank the starter. It worked fine - I would not recommend this on a street car - It would make the car easy to steal! But for the race car, It made it easy to start and run the car - and turn it off - from the engine compartment. Great for troubleshooting -somehow handy for a race car! For a street car and a powered distributor, you could interrupt the power connection to the distributor. On this distributor, that is the red wire connected to the positive (+) pole on the coil. As supplied, I install (crimped and soldered) a ring terminal on the wire end to insure retention. But you could easily replace that with a push-on spade-lug terminal pair. You could even use a type 56 GM terminal and single-cavity connector and make it look almost stock. Just yank it off to un-power the distributor, while leaving the ground and coil control circuit alone. Note that I cannot say for sure that pulling all three connectors at once is what killed that module. At least the guy fessed-up to having done it, and a little while later a failure. - Seth Emerson In a message dated 8/3/2015 8:30:49 P.M. Pacific Daylight Time, fastvair at yahoogroups.com writes:
That prompts a thought - it would be handy to have a kill button or switch in the engine compartment - just because.

For a breaker point system, it could be a button that opens the lead from the coil to the breaker points. For that matter, you could even ground it, for the period of time it takes to kill the motor.

If someone wants to put a kill button on a car with the electronic distributor, what would be an easy/safe/reliable way to do it?
