Yeah, but probably not enough air to make much of a difference.

-Sorry for the bump, but i was wondering if there was any updates to anyone who has tried this? Is it still working, etc! I'm running a turbo xs dual stage boost controller, currently at 13lbs in 5th gear. I want to run 16lbs of boost.
-Reading thru this thread, it seems like an economical way of getting rid of fuel cut, but I'm still a little skeptic as i dont want to hurt or break anything.

-Joe

These work from what I've read from others. It should be fine as long as you don't up the boost too much.

-Well all i'm looking for is 2-3 more pounds of boost. As i've heard the td04 is efficient up to 16lbs.
-It would be nice to see a DIY write-up on this but i'll go back thru and read it again to make sure i get things right.

-So here's my setup. I went to Harbor Freight and picked up these items:
-1 #68198 1/4 x1/4 male-male coupler
-1 #68220 air inline regulator
-2 #68209 air brush adapter
-From auto zone I picked up:
-1 #47311 3/16" vacuum restrictor
-1 #47149 vacuum check valve (not used yet)

-My current setup:


-Parts:


-After assembly:


-The final product:




-I'm going to test this right now and let you guys know how it went. Let me know if I did something wrong and or what needs to be changed!

-Joe

-So far so good, no fuel cut. But the real test for me is 5th gear on the freeway. AFR's still look good on the wideband, high 11's and low 12's.
-I'm going to be moving to San Bernardino CA. tomorrow so I'll post here what happens, if anything, once I get there.

where'd you use the check valve?

I didn't use it. I got it just in case I needed it.
Joe

so do u need an mbc to run this are do u not need one and also what is a good mbc that you can get with out ordering online like a napa are auto perfermace store

i don't think napa or an auto parts store would stock a MBC. there's a couple DIY threads on here about how to make one out of parts from home depot. Search home made manual boost controller or DIY manual boost controller.

To up your boost past the stock boost lvl you will need a MBC, but you will only need the FCD if you are going past 13PSI i think

Yeah, stock is at 13psi

I thought stock was something like 8.7 PSI...

stock boost is at 8.7, but fuel cut is at 13psi

Caveman, you should paint the yellow caps the same red you painted your other accents. I think it will look real nice!

I just might have to do that!

ive been using the 2way check valve and boosting 15lbs with no problems yet!

Could one not use a check valve (to allow vacuume to get to the FCD) in parallel with a MBC backed down so the FCD sees 10 PSI but you are boosting 15 PSI? The check valve would block the boost.

I'm sure you could do something, but tuning and configuring them would be kind of difficult I think.

Yeah but do you have any mods or did you just crank the boost up? Becareful not to blow your engine up. I'll be the first for ectra parts

Dumb question but how do u know if ur car is hitting fuel cut

Trust me you will know. It's like hitting the rev limiter with a little more whiplash effect lol

Joe

Ok so not like bucking or anything like that

Yeah, it's like all the power is taken away. It's pretty noticable.

hmm ever since I turned up the boosr to 11psi my turbo is takinf for ever to get power
