Re: mbc no good for low psi?
i got an 11.somthin psi spring too, might just throw that in there, what will 11psi on a ford 60/63 on a Ls motor do?

Re: mbc no good for low psi?
Why not shim the 6 pound wastegate spring to what ever you need and not even use the MBC?

Re: mbc no good for low psi?
i made a post about that actually, i was thinking about that but its gona be a bitch taking it apart and shimming it until its right, probly just gona run 11psi :1

Re: mbc no good for low psi?
Run the 11psi spring and it will end up being about 9.67psi anyway due to IC pressure loss DEPENDING on your vaccum source (manifold = higher, turbo = lower).

note: i use an internal wastegate set at 6psi Easiest thing to do... |
Re: mbc no good for low psi?
One question... If you were to use an electronic boost controller would that help reduce spool time by keeping the wg closed until the last possible second?
Ok I looked into it and the answer is yes.. But does anyone here know if its really that big of a difference? It doesnt sound like a big deal unless I'm competing in drag events trying to shed one tenth of a second... |

Re: mbc no good for low psi?
i had a cheap egay mbc that did the same thing. couldn't go any lower than 11psi. ended up just not using it for the time being because even cutting the spring didn't change anything. maybe i didn't cut enough off.

If I'm not mistaken, that's how external gates work already, but I think I'm wrong...I forget. Internal bleed and fluctuate and suck. JP |
