Yes I know. I realize that, but what I meant is that I think Sleek Silverado is running a stock converter like me and I was curious as to if it had something to do with the stock converter.

I am aware that it doesn't make any sense though.

 

Wouldn't having less Vacuum cause a harder pedal due to lack of vacuum assist?

 

I do have a stock verter.

 

No vacuum or almost none causes a hard brake pedal. For ideal braking you want at least 19in of vacuum. With larger cams vacuum tends to fall. Most streetable cams, depending on how large they are, will drop your vacuum to anywhere in between 11-17in of vacuum. That's where you feel that brake fade.

 

I don't see a stock converter causing brake fade. The one advantage to having a higher stall converter is that it doesn't transfer as much power to the wheels in the lower RPM's(when you're slowing down/coming to a stop) as a tighter/stock converter would. This is only due to the higher stall TQ converters being "loose" up to their rated RPM range. Getting a higher stall by no means would be a cure, you're brakes are still weak from lack of vacuum. Vacuum canisters may help though I really doubt it. All they do is give you "reserve" vacuum, but it will still be the same low vacuum. An in-line vacuum pump to your booster will definitely help as you can adjust vacuum from 19-27in depending on the pump. Again, hydra-boost systems are also a great solution, since you will no longer depend on vacuum, rather hydraulic pressure.

 

5 in. Hg at idle. Definately the cam. Anyone have a spare hydra boost?

Is it hydra or hydro?
