i have an idea i've been toying with for a three stage boost controller. I wanna run one setting at the wastegate pressure(8psi), one at 10 psi and the third at 15 psi. I'm cheap, poor, and love to do things my own way, so instead of buying an expensive dual or quadstage MBC, or a EBC, i decided to build my own MBCs. the concept is simple, but i'm not 100% sure if it'll work. here's a diagram. do you think it'll work?



also, what modifications need to be made to make this work? what am i missing?

 

is this for a honda? what ems?

 

yeah this is for a honda..sorry for the lack of info..it was nearly 3am when i made this post...it's gonna be a b16a2 boosted with a garrett t3/t4 60 trim .63 ar...head is gonna have supertech valvetrain and gsr cams skunk2 cam gears..block is stock sleeved at stock bore..eagle rods, cp pistons, acl bearing set, and arp hardware holding it together...3 inch downpipe..with a thermal 3 inch exhaust...tunned on neptune rtp...all going in my DA...

I say try it out. I was planning to try something like this for a 2 stage set up. I didn't think of the purge control sol though. I was planning to use a fuel tank switch from a '93 F150 to change the vac routing to with / without MBC.

 

i wanna see if this will work before i put it on..this is my first tubo build that i complete 100%..i started one some time back..but decided boosting wasn't right for me then..so in all reality..this is my first turbo build ..everything is gonna be done by me, except the tunning...i just want someone more experienced in boosting to let me know if this set up works..i would hate to mess anything up...and yes..i searched...

Do yourself a huge favor and cut all that craziness out and just put a simple boost solenoid on there and control it through hondata.

EDIT: The solenoid is like $40 (I think that's what I paid for it at the dealership). So unless you can get the 3 mbc's, the 3 purge solenoids, and all the wiring for $40, then this is cheaper too for you.

 

Dunc is right Hondata, Neptune, and eCtune all provide EBC functionality that you should make use of.

EDIT: Also to answer your original quesiton, I have seen the purge solenoid used successfully in this fashion before.

making this will cost ledd than $40..and i'm not using hondata..i'm tunning on neptune..my bad...

Ok, it's your call but the one EBC solenoid is going to be much better of a setup in terms of controlibility.

awsome..that's almost exactly like mine..except mine doesn't have diodes...so this should work then,right?

 

bump

 

I too say go with a ebc solenoid, since when was $40 expensive? $40 or new engine due to boost spike?
