Reply to "2457 Engine Setup"

The first set up has a blow through carb in the box and the second is fuel injected with a throttle body and plenum sitting on top a tunnel ram base. The biggest issue with both....neither one is intercooled. It depends what the static CR is but without intercooling or some other means of detonation control such as water/methanol injection, I bet neither of those systems can safely run more than 1/2 ATM of boost. It also assumes the turbos are sized to spool within an rpm range reasonable for how the engines are cammed.

Back in the 70s and early 80s, set ups like that showed up now and then because making 450-500hp was a bigger deal but today a 500hp naturally aspirated street engine is common place so why bother with all the additional overhead, complexity, and weight? I have an acquaintance with such a set up and he has a box full of bent rods for his trouble. Today TT V8 street set ups are routinely North of 800HP (some well North) and they are a blast in a straight axle straight line car but using it in a Pantera? Maybe an unlimited open road race car but other than that I'd take a nice running NA engine.
