Very close to finishing my set up, wondering if it's worth it to cheap out and get a mbc or save up and wait for a ebc?

questions:

-Are mbc's annoying/hard to adjust?

-do they hold high boost (17-18psi) well? anyone running high boost have a mbc?

-Which brands mbc's are good? turbo xs/turbosmart/ect..

 

What kind of setup do you have? I used to run a greddy profec and had problems with it so I switched to a Joe-P manual boost controller.

 

I have a Turbonetics MBC, it is easy to adjust and so far it holds boost pretty well..

1st and 2nd gear reads steady 10PSI..3rd gear reads 9.5PSI and 4th gear 9 PSI so overall so far it just looses 1 PSI at higher gears.. Thats when we tested it..

I now have it set at 9PSI

Yeah, thats what i was afraid of. but 1psi isnt that bad. Anyone have a mbc running high boost? im wondering if the drop off with high boost is the same or worse than low boost?

fjt, where did you get yours from and how much did you pay?

 

I have mine set on 10 psi and it holds it steady throughout all gears. You can get them from boostcontroller.com... I like it better than the profec because it doesn't give me any problems... As for setting it goes, its not that hard... Just gradually work your way up on the boost controller until you reach what you want and you're done.

 

with some of the electronic ones you can set different psi for different gears to gain better traction. as well as having a low boost and high boost setting which is nice. but the Manuals work just fine. im using a turboxs and it works great. i also have a hallman manual for sale if your interested. and no they are not anoying or hard to adjust.

 

anybody runnign the turboXS dual stage? if so how is it?

thanks guys

How do you know it's the BC? I have seen plenty of setups that have fluctuating boost with nothing more than a wastgate to control boost.

They should really call boost contollers, wastegate controllers.

 

The only thing i didn't like about my MBC (ebay ball/spring type) was that boost would increase a bit as the weather got cooler, thus needing minor tweaking w/ temp changes. It cost me an easy win one time because i kept hitting my boostcut

 

this is fafsa at john's.

how much boost were you running?


someone answer my question about how boost holds with mbc's at high boost

 

its really a tradeoff, one way or another, the mbc has the cheap price, the electronic one has the high price, but you get consistent results, i would rather spend the money on the electronic one, rather than having the manual spike and destroy your motor

It seems to be the exact opposite in practice. MBC tend to be very reliable and consistant vs. EBCs that tend to reset, not hold boost, not hold it consistantly etc.. look at J Davis' Profec thread https://honda-tech.com/zerothread?id=1058473

I have the turbo xs manual and have been running 18lbs for a year with no problem.
When is does get cooler out though, it tends to up the boost by a pound or so, which is easily corrected with a half or full twist. *shrug*

i forgot to say that evo 8 guys on evolutionm.net run MBC's anywhere from 19psi to 20+. Infact, i think about 50%-60% of them run Hallman's.....check out some threads and read members sigs (most of them will have Hallman EBC on there LOL)

which does everyone recomend hallman or turbo xs?

 

I have a Hallman Evo Rx in my RX-7. It's a great MBC. I've run as high as 14 psi with it and it's always been super conisistent and reliable. It was a little pricey since it comes with 2 springs and really light ceramic ball. It's a very nice looking piece though!



Sonny

 

thanks, sonny. im trying to also narrow the choices down, so far its either hallman or turbo xs

also want to know what everyone thinks about the 2

hallman vs turboxs

 

I personally wasn't happy with my greddy profec B, I'm happy that I didn't have to pay the high retail price on it.

 

the turboxs is 10-20 more than the hallman, is it worth it?
