^Any price if I send mine in? Hmmmm looks interesting....I am guessing this will improve throttle response?

6hp isnt bad,... my question is, how much better does the throttle responce feel?

Hi,

Yeah it's a 6HP gain, I would imagine the gains would be far more pronounced with an upgraded intake manifold. There's no idle issues because it's a match-ported T-body in other words we did the throttle plate.

Unfortunately we don't need the cores, we have plenty here!

Thanks,

What are the mods of the car on the dyno graph?

To be honest, I dont' remember it was awhile ago. I just had these dyno graphs listed under "throttle body" in my new products folder. The demand isn't there for these throttle bodies, so we're just selling what we have.

Cheers,

Sorry we're not taking cores at this time. We actually have plenty. We did a limited production run of the throttle plate and I don't think we're planning to do anymore unless demand picks up. Please let me know if you're interested in the ones we have.

Thanks!
