Boost controllers, MSD ignition and boost settings
« on: October 03, 2016, 11:14:11 PM »

Hello, I'm looking at getting my head around which type of boost controller to get for my xr2 B6T, with the VJ 11/14 hybrid...

What type of boost controller do you use, and what type of boost settings do you use on the electronic controller, has anyone tried the RPM boost settings ?

How does a MSD ignition 6 AL rev limiter affect boost rev's ?

Aaand, how does the Rocketchip affect boost, including Rev limits...

You guys are great !  ;)

For a electronic boost controller I would recommend a GFB G-Force II they are made in Australia!
 Not sure how it works/feels with the rev range considering I have a N/A, but its what I' ll be running on my car.

Yes, gotta support local manufacturers these days, although I am always tempted by Japanese made quality...

Like the Greddy Profec Oled electronic booster, aesthetically it looks awesome and can be uupgraded with a racing boost mapper add on for even more precise boosting... like from RPM and by gear shift...

The GFB G-Force II is cool looking, and has similar features to the base Greddy Profec Oled, but requires a vacuum hose from the unit through the firewall, whereas the Greddy has a separate unit in the engine bay with a shorter vacuum hose connection to the turbo. Not sure what difference that makes, but I read somewhere having shorter vacuum hoses can make the readings more accurate.

The Rocketchip doesn't affect boost in any way. All it does is give you correct fueling for higher boost levels so that you don't blow up the motor, and raise the rev limit to 7200 RPM.

I use an old school manual boost controller made from plumbing fittings. I've uploaded a picture of it to the forums here somewhere.

Let us know how you get on with the electronic boost controllers - I've heard many folks have issues with theirs on a Capri/323 with the stock turbo. It seems to spool too fast for it to respond and reliably control boost levels

Necro'd.

Sure seems like any boost controller will cause boost creep. I have a dual stage controller that doesn't agree with my un-ported wastegate. I think even if I were to have the stock exhaust on, that wastegate must be just BARELY adequate for these cars.

The only real solution is to port your wastegate

I went with a 13/16" hardened steel drill bit and finished with an arbor to obtain 0.86" and leave enough overlap to handle the 1.02" flap (which wiggles a bit on the Revit it is mounted to). That works really well with my 2.5" cat back system (which had given me issues even when I had the stock turbo). Now, I'm running a vj11/vj14 hybrid turbo on it and never see boost creep. Pretty much any change to the stock exhaust will cause boost creep if you don't enlarge the waste gate throat.
