I have gobs of hp, but I am limited by my boost controller and my 7.5psi WG spring in my 44mm Tial WG. Is it an easy switch to put in a 10 psi WG spring? Is it cheap to buy one? Where can I get one? I wanna be able to boost 20psi and see what my numbers are. I have such a capable engine and I almost feel like I am cheating it out of it's fun by only boosting 15psi. Thanks.

 

Its very easy to change springs, takes maybe 20min max. Either order one from tial or get a boost controller and don't even worry about the spring.

 

Dezod.com has what you need:

for the .44 Tial WG they offer springs from .3bar to 1.4bar (3.63psi-20.30psi)


And they're only $40

 

From what you're saying a single stage boost controller would be a great idea.


It works like this:


It's basicly a boost controller with 2 settings, off and on. Off, or LOW boost is dependent upon what spring is in the WG. The next, ON, is dependent on what level you set the boost controller at. All wired to a switch with only a 12v power lead and ground. TurboSmart makes on, i believe. I'll see if i can find you one. Easily switch from the stock spring to a HIGH boost setting at ANY time.

 

Here it is:






The Turbosmart Single Stage Boost Control Valve Switch allows you to switch between two boost levels from inside the cabin, using a "Rocket Launcher Switch".

The low boost setting is the "stock" boost level determined by your car's wastegate actuator.

The high boost setting is fully adjustable and uses the same detent system as the Turbosmart "boost tee", which makes adjustment easy and holds your desired adjustment... just set it and let go.

And, it also utilizes the same unique ball and spring design to bring boost on faster. The wastegate will not "see" any boost signal before your dialed-in bost level is achieved. The result is faster spool-up and more horsepower sooner!

I appreciate it, but I already have that. The downside is you can only double the wastegate spring psi. I have mine fully open and I can only get 15psi. If I upgrade to a 10psi WG spring I'll be able to get 20 psi for only 35 bucks.

 

This is a S2000 not a Honda Civic. Buy an electronic boost controller. I suggest any of the GReddy line. A EBC will allow faster spool times of the turbo by keeping the wastegate absolutely completely closed until your set boost is hit, stop boost creep, and keep the boost peaked throughout the RPM range without letting it drop off. Relying on only mechanical means of boost control creates less responsive boosting and risk of boost creep!

They are easy to install, and I swear you will feel a noticeable difference even if you don't run any more boost. Your peak power will be the same, but your power band will have some steeper curves getting there. Let me mention again that it's also safer for your investments under the hood, especially as you get closer to fuel, boost, or power limits of your set-up.

 

Didn't know that, thanx!

 

What if I get an 11.6 psi spring. Will that change anything?
