So I was thinking to myself whats the difference between say an air regulator and a manual boost controller...then I got to thinking hmmmm maybe this will work. I installed it today and i just wanna get some opinions on it before I go and do something crazy, like oh I don't know...blow the engine...

The air flow is going from the turbo vac nipple to the wastegate actuator, should it be going in that direction or the opposite...WG actuator to Turbo nipple???



Feedback welcome - Positive as well as Negative. Thanks all.

You've effectively made a vent-type manual boost controller similar to an HKS unit. They work pretty well you just have zero control over rate of attack et cetera.

i would think that the incrementing needed to be precise with boost control on these cars might not be all that easy with that. If its on a fairly stock car, you want to see 10 psi max and that is like rated for 16 times that amount. You would likely run in to problems dialing it in but it may work

maybe i don't know what i'm talking about

Guys I can honestly say damn... this thing works very very well. Just took a few test runs and there is minor lag (steday 5lbs) until about 5K then it goes full on to 8lbs(where I currently have it set). It feels like there may be a bit of a boost leak due to me using the crappy stock pipes but other than that it's good. I just have to dial in exactly where the secondary boost push is. Doesnt feel as though im running Full Non-Seq... There is a dial on the gauge that has groves cut into the inwards parts to measure the lbs you want. Though the gauge is set to like an obnoxious amount of lbs, its pretty simple to dial in to keeping it below 10psi for testing purposes. *Skadoosh*

Just a thought but the attack/response time may be due to the length of the actual hoses connecting the unit... Hmmmm..I'll keep you posted. Thanx everyone!

By the way, whats a stock skittle running anyway? HP to 1/4 time?

Looks nice, but I don't see the point of having a gauge that you cannot see while driving. Since you can't boost the car with the hood open (without a dyno), it seems to be a waste of a a gauge. Perhaps a gauge with a maximum pressure resettable needle would be a better choice.

Its a Manual Boost Controller...

Reading is FUNDAMENTAL

i think the gauge just happens to come with the device. Without it its just another valve type controller i would think. The Gauge is pointless unless its used to SET the valve to the desired PSI without it actually being operated

Dream Theater

Yeah the gauge is just there for if you were running it on say a steady flow air compressor to see what the steady current psi was... I could probably remove the gauge but then i'd have to plug it and that's just pointless.

I think this setup could have problems in the wrong circumstances.

The regulator allows air to flow from input to output until the input passes the set pressure, right? So the wastegate could receive less pressure in an overboost situation. In addition, the open flow at low boost means that the wastegate should start opening earlier than it would with a ball & spring MBC, hurting spool.

Maybe I'm confused about the installation.

Dream Theater

Installation is the same as any MBC... from turbo to WG... the dial just allows you to open the loop and close the loop at your discretion. Allowing more air or less air to flow. Basically acting as a pill.
