Which is the best MANUAL (non-electronic) boost controller, assuming stock 951 with aftermarket chips?

Which MBC is the best bargain?

 

Good reviews on the Accuboost MBC, comes with spike protection and acts as a boost enhancer as well: http://www.boostsciences.com/accuboost.html

 

So if you have stock (single port) wastegate, you would require a check-valve style manual controller. (Bleed valve is the other style, ala the manual controller sold by lindsey)
Of this type I have used the Lindsey Boost Enhancer and Reliaboost - reliaboost has a small bleed hole which is preferred as it reduces boost spiking. It blends into the engine bay a little better also, bit more stealthy / less bling bling than the LBE. Also can be adjusted without disconnecting the signal hose, unlike the LBE.
I was expecting the dual port wastegate / manual controller would hold boost to redline, but unfortunately not the case, still get a drop off from 15-12 with my k26-8.
Are people holding boost with a manual controller for other turbos such as T04Es?

 

I had a manual bc with k26/8 held boost to red line same with to4e.

 

I have an accuboost, they offer a ceramic upgrade for it as well.

I love the Evolution RX cockpit adjustable check valve type controller, has a ceramic ball. I just so happed to have mine for sale.....any takers?

 

Can you post a link to the Evolution web site ? How much do you want for it ?

 

Sorry guys, it sold already.

 

Hally, is your Tial 38mm WG shimmed or new?
I got LR wastegate and MBC - holds to redline.

 

I have the LR MBC and stock wastegate... works fine for me :P

 

Reliaboost with the spike hole and shimmed wastegate work great for me.

 

bought it new, .8 bar spring from memory.

 

Not to sound insulting, but if you're running a dual port WG setup, for best results, remove your CV and reliaboost setup and use the MBC (or regulator) to control both sides of the WG. One hose comes off the banjo bolt and tees off to the input port of the MBC and top port of WG. Side port of WG connects to outlet port of the MBC.

 

hah, nothing that exotic about my setup. I'm running a tial in dual port mode with black **** MBC and i still get boost rolloff. Others such as Jake951 have posted the same issue.
