That's impossible to say without more info.

Which engine and is it stock? What's the condition of said engine?

Well my 61 has been great so far. I have a lifter that makes noise when it's cold. The 80hp is said to be the most reliable version, but they're all pretty stout from what I understand.

Mechanically, the Corvair engine seems to be the last thing in a Corvair to fail. It can outlast the body, suspension, brake system, the differential... even the owner! (It often survives a lot of mishandling and abuse from amateur backyard mechanics and previous owners!) The well-maintained Corvair engine has even won the faith of the aviation crowd... enough to often be fitted to single engine aircraft, when a failure of the engine could be a life or death situation.

It takes a licking and keeps on ticking!

lol my response when someone tells me they aren't reliable is exactly that part about the aircraft community.

Yes but when I'm planning on getting said cat I'm looking at ( the 62 ) I want to know how far I can push the engine physically before it goes ghost

I bought a new 62 Monza coupe 102hp, my girlfriend and I took a trip from Kalamazoo Mi. to Detroit. On the ride home we decided to see how fast we could make it back to Kalamazoo. We came from the Windsor tunnel to Kalamazoo in 2 hours 5 minutes. I was running 90 mph plus most of the way. That's a bit over 150 miles with some of it in downtown Detroit. If you rebuild that engine right you can run highway speed all day long!!! That 62 had a 3:27 diffy & 4 speed. I now run my 64 110 hp 75 & scares the crap out of me :eek: , when your 18 you have no fear. ::-):

What do you mean "push"? Do you mean abuse it? Foot flat to the floor beating the balls off it? Throwing nitrous or something else on it? Please be specific.

Not as weak a link as the 164 inch engines but the stock cast pistons won't hold up under a huge shot of nitrous. After that i'd suspect rod bearings and issues related to elevated cyl. head temps. In that order.

Good troll.

Full throttle beating with nitrous on a 55 year old 80hp flat 6? Should work out well for you.

Seeing as the motors have been made to make 250 hp with the Yenkos I'm guessing a 100 shot would be fine

I'm just curious as to how far after that she goes ghost

With a stock Corvair engine. It won't last long. Even performance built Corvairs have to be purpose built for any kind of endurance racing. If you are not familiar with Corvair engines you should start by educating yourself on what they can and can't do and how to build them by getting some of the books out there such as How to Hotrod Corvair engines and Bob Helt's Complete Corvair.They are a lot more tedious to build than any conventional 4, 6 or 8 cylinder engines and require some specialized machining operations to make them last. Also, plan to put out a lot of money. The engine parts are more expensive than more common engines.

Yenko advertised but never produced 250 horsepower engine which was listed as Stage 5 for public consumption. You also have to remember that those numbers were in GROSS power ratings. Today that engine would be hard pressed to put 140 horses to the wheels. Most 140's will put about 100 to the wheels.
There are very few modified Corvairs that put an honest 200 horses to the wheels and even fewer that are naturally aspirated. Ray Sedman built an EFI/turbo car that put 360+ to the wheels. But that is most likely a $20k build by the time you are all said and done.
