This motor belongs to a friend of mine who used to work almost exclusively on Indy Cars. The basic motor was built by Infinity for the Indy Racing Series, these throttle bodies which are what I sought to highlight with this crappy cell phone video shot in poor lighting, they are very unique outside of some Formula One/F1 engines. The throttle bodies are fascinating, they are a double lobe design similar to a Roots type supercharger but, with precision machined venturi's which open from the precise center of the intake ports and offer literally ZERO restriction to intake airflow when wide open. There are no butterfly valves at all...awesome but way too expensive to build for production engines. This motor and as many as 5 more are for sale, $30k USD WITH these TB's and other motors are $20k-$25k USD without the custom ITB's. I can provide direct contact information for serious buyers.
