Build Thread:
Current Mods: Removed restriction in ram air to allow better cool inlet air flow.

Sealed ram air to air box with A/C window seal

K&N air filter for reduced air filter restriction

Replaced air lid, duct, and MAF to increase airflow in intake system.

Replaced Y pipe for high flow exhaust to reduce exhaust restriction.

Replaced flywheel with lightened (13lb) flywheel to reduce spin-up load

Planned Mods: electric forced air to intake? Needs at least 1000cfm at WOT.

More reduction of air flow restriction at engine. larger throttle body? ported heads? No cam change wanted.

Looking for options for electric assist hybrid w/o engine/transmission mods. Possibly electric at driveshaft (drive in neutral, engine off) or (???) electric to front wheels.
