I had a friend look @ those pics & is a Corvair expert.

He had said :
" The stock Carter YH side draft carb is O.K., but limits boost on a stock Corvair. It has to be a real limiting factor on the larger engine and better turbo. The Q-Jet would be the carb I would run. If he is running the YH, I would suggest the carbs with a body casting number of 17_ _."

He also commented by saying,,, LOL:
"Now I see where the old Corvair turbo stuff is going. :-) "


Just some FYI.

Yes, I can see that you could easily inject too much water & snuff out the spark, methanol injection is the better way to go now a days.

I know all about the early Nova's bad suspension.
My good friends 66 Nova ,built 406 SBC,drum brakes & a street car, racing on the streets & many times @ a race track ,one I would race & compare/race my L6 Camaro to.
He never beat me BTW LOL
Thanks for the info!
