How to bypass the BBC to get more boost



bypassing the bbv will only cause you to enter boost sooner and when you don't need to be in boost. also you will lower your gas mileage and raise the chance of having part throttle kr that can damage the engine. like said leave it alone.

Maybe you should read up just a little bit and the mysteries of the world, including what the S/C 3800 can do for you! It's all here, you just got to put a little effort into it (search).

Don't say that FFDP, then he'll be posting up wanting to know what a Miss is and why parts of his plugs are missing! Lmao
If you haven't read about Modding these engines just keep your hood closed until you catch up on more reading.
Search, search, and more search. Thats the best advice I am giving.

I ain't Retarted I have built a lot of engines and I know I can't just slap on a smaller pulley BC u need to put new valve springs rockers etc

There is no more boost. The boost controller bypass's the boost during casual driving, when you put your foot down the valve closes and gives you everything the supercharger has.

your way off base, you need headers, and a i/c or e85 to run that small a pulley. or boom. you dont "need" valve springs or rockers.
 
That's probably a waste. Your paying for convenience of having stuff put in one spot for you. Go make your own intake and buy a set of headers and a scan gauge then start from there
 


It comes with brand new valve train internals and shift kit different gear for tyranny and stronger 4th

$2500 no intercooler and press on pulley.

I rather have 1.9 rockers and a intercooler than new valve train.
 
Then what should I do for the head if I'm wanting to put the m90 supercharger smaller pull like a low three

Start hear. If you look at the first 3 or 4 threads in the general tech section they talk about headers, rockers exhaust etc...


If you want to go turbo or stick with the M90 supercharger. Turbo faster but all the money up front.
