eBoost2 on Twin Turbo's

Has anyone or does anyone know how to hookup the eBoost2 boost controller on a twin turbo Camaro with external waste gates using the 2-port method?

I have the 1-port method working but every time I try the 2-port the car over boosts.

Thanks in advance!

What wastegates are you using? We have done this set-up with the new Tial MVR's so if that is what you are using I am sure we can help you out. I know we had to plug the extra port on the top but if you want more specifics just shoot me an email at: sales@ipsmotorsports.net

Hi Jeff, I really appreciate the help. My system uses Turbosmart Ultra-Gate 38mm waste gates. The instructions for the 2-port method I tried are shown on page 7 of this document (http://www.turbosmartonline.com/inde...ownload&id=361), but it did not work for me; it kept over boosting.

Here are diagrams of the two methods, I've been trying the second:

I'm thinking about trying method 1, but I'm not sure my system meets the "high back pressure" criteria.

Method 1 works best. All of the LSx twins we have done, we have not had the need for method 2 yet.

I set all of my TT LSX cars to this, initially.


SP1-0, GP-6 SN 20
SP2-10 GP-7 SN 20
SP3-20 GP-8 SN 20
SP4-30 GP-9 SN 20
SP5-38 GP-10 SN 20
SP6-48 GP-12 SN 20

This should be-
SP1 6-7
SP2 8-9
SP3 9-10
SP4 10-12
SP5 12-14
SP6 14-16

Overboost is 18 psi, which will flash at you, and then revert back to lowest boost setting. It basically dumps the solenoid for engine protection. You need to set your overboost to what ever your max boost is before it breaks parts, or run out of fuel, etc.

Thanks Louis, I'll try that one.

Bobby is right, method one is ideal and how we normally have them setup in our TT kits.

Do you still get the benefit of improved turbo response (i.e., gate valve float prevention) using method 1?

Method 2 always seems to over boost in our trials. M 1 will still help response. The eboost can be set to start cycling the solenoid at different boost pressures. Until it hits that psi setting,it will keep the solenoid from bleeding boost to the WG. Profec B's and other systems have a setting like this. We find that method two really works well on small displacement high boost applications, while the recycle effect helps stabilize the WG at high pressure and it seems at lower pressures higher cubic inch engines to hang the gate open longer.
