Re: 69 Camaro front valance and spoiler on a 67 c10?
Exactly... carbureted turbo setups don't work well.... not nearly as well as efi. A blow through carbureted turbo (where the turbo is before the carb) are really hard to get right. You need a high cfm carb, the jetting needs to be perfect, and you need high fuel pressure and float bowl air pressure.
A suck through (where the carb is before the turbo) is much easier to manage. Because the air is being pulled through the carb by demand rather than being forced into it. When the throttle body closes the pull stops. This is why superchargers are so effective, and usually have the carb(s) on top.
both have disadvantages. Push through are really hard to get right and maintain tune, while the pull through turbos run the risk of ignition in the turbo.
superchargers dont run the risk of ignition because they dont use hot exhaust to spin the turbo, they are belt driven....but they rob initial hp.
like my performance/dyno teacher used to say "theres no free lunch"
