This would pertain to SD800 engines primarily. Ive read on different threads on different boards some talk about the Boost Bottle. Ive read to leave it, Ive read remove it, and Ive read its fine but to big or to much volume. Im wondering if anyone has messed with the size of the BB? I have access to materials to make my own BB and could easily control the volume. Any idea's on how much less volume should it be?

Thanks

I don't know about the 800's, but the one on my 700 is 220cc, the software tells me it should be 300cc ?

I kinda thought pulling the bottle on the flatslides with unhooded nj's might help pull more fuel from the added reversion. But then someone posted that they found it went lean in the middle? which blows me theory away. Was their gain just from pulling the bottle or from the change in mixure? in which case a jet change could've done the same thing. Don't know, just thinking out loud. Usually when something is "tuned" to help one part of the rpm it takes from another, it's always a compromise.

i call it a bog bottle . in a drag race the bottle looses
