There's gonna be a new option before long... based on the Hennessey dual intake design... coming soon...more air and 1 per turbo drawing air from outside the engine compartment. I just need to find a weekend to leave the car at Black Market Racing..... 4DR's idea, and one I like. We hope to use the dyno there to show what difference it makes and have a jig made so it can be mass fabricated.. It won't be anywhere close to the $2300 Hennessey wants for theirs.
Give us 4-6 weeks to have the prototype and the stock vs. this prototype dynos (same day, same machine, same weather, same dyne, same car)
