<VV> Cams for Turbos Re: more on camshaft

[FrankCB at aol.com]

Mark,
    "able to race kids from light to light" means you  want minimal turbo 
lag, fast response from idle and boost at relatively low  revs.  Turbos generally 
need cams that have little overlap between the  intake and exhaust valves 
opening.  This generally indicated a stock  OEM-type cam like the one that came 
from the factory with the stock 180  engine.  OT-20 sounds like it has more 
overlap than the OT-10 which may  itself have more overlap than the stock 180 
cam.  Large lift with turbo  cams is good, but large overlap is not.
    Read the chapter on Turbocharging in the Corvair  Basics Manual to see 
what else you can do to get the kind of performance you  want and "beat those 
kids".<GGGG>
    Let us know what you learn and what you decide to  do.
    Regards,

I found  out from the supplier of the camshaft  that I had bought it is a 
OT-20. I  have no idea what that means. I also got the part number c8802. They 
said the  cam will work in my 1966 turbo motor OK, however it would not be their 
first  choice. 
Has anyone used this camshaft in a turbo motor  before? What the opinion of 
how it would perform? Or else, what should I get  instead?. 
The engine is not modified except that it is bored .20  over. I'm looking for 
something that will do good with high rpm and still  build good boost. Or, am 
I better off with low rpm and higher boost.
Just want to be able to race kids from light to light here in  town...

Thanks Mark

1966 Corsa......may run again someday
