Im looking to boost prep my 51ida weber (7-10psi max on stock s5 turbo). From what I read I need to do 2 things for sure.

*1. Vent the fuel bowl into the carb hat so it sees the equal pressure. (Line from fuel bowl to carb hat area?)

2. Swap the brass float for a plastic float. Because the brass float will crush above 6psi. The plastic float ot good until 20psi.*

Other things I have read are unclear. Its obvious that i need to seal any and all areas that can leak. But what areas do these include?*

1. What else besides the "hat" needs to be a sealed?

2. Do I have to seal the throttle shaft? If so, how would I go about doing that?

3. Are there any other modifications to the weber that need to be addressed?*

I have everything else ready to go. I just want to be sure I get my weber in order before setting it all up.

If you encase the entire carb in a pressurized box, it can cut down on your tuning issues alot (seals and boost reference to float bowl).

but that is about the extent of my knoledge of blow-through carb stuff.
