i need experianced homemade MBC opinions...
i have searched and couldnt find what i am looking for. i want to know what people who have used a homemade mbc think of it. i am considering making one, but would like to know what i am getting into.
if have not used one dont post please. i am sure this this has been beaten to death, and im just a sucky searcher.
thanks.

i got one home dept style. cost a total of $12 and its easy and fun! depending of the spring rate of the spring it will have different characteristics. the harder it is, the more boost risies per each turn. mine is real senstitive, i can go raise the boost more than 8 lbs in one turn of the ****.
anyways i really like it. before i would get 12 psi at 6k, now i get 12 psi at 4k!

how did you make it? the geosites link for the mbc isnt working for me, if that is the one you used.

I made mine from a local hardware store. It's alright i guess for $4, but i'm going to buy a real one soon. It fluctuates way too much. Mines alittle different from the link above. It uses a brass T with two nipple ends and a bolt to adjust the spring pressure. Maybe i just need to try another spring. Mine will go up like 3-4 psi every 1/4 turn.

Re: i need experianced homemade MBC opinions... (xenocron)
I did the mod in the link I posted above...I think it cost me like $10 in parts from McMaster and I had a machine shop drill the small hole for $10...so basically $20 and I have a trick little MBC...
I upped boost to 8 psi (on my gauge) from 3 and there is no spiking issues really. I do notice from my datalogs that boost does creep from 8 down to maybe 7...but the spool seems a touch quicker.
I have an extra if anyone wants to buy it off me...
