just wondering?

 

Instead of relying on manifold pressure to close the gate, you use the co2

 

i saw on some cars the co2 tank hasd an air regulator. what psi are they feeding the solenoids?

 

yes also most use NLR to control it with co2

 

We regulate ours at 60psi

 

an NLR is NOT required to run co2!

We run our Ek with just a solenoid and CO2!

 

werd

 

what are the benefits of using it ? just more reliable ?

 

more control. and it lets you run a soft wg spring and still make 40+ psi

 

you can do the same by running one solenoid on the bottom of the gate and one to the top. Then you dont have to fill that thing up

 

I agree, thats why I said most...

 

 

what do you use to control 2 solenoids

 

A good ECU.

Run one standard and run the other off a seperate table. When you need more boost pressure the second one comes into play.

 

can this ^ be done with aem?

 

can some one please put a layout with the co2 bottle to the waste gate using
one solenoid,thanks

 

I think it can be done with V1 and V2. Not 100% positive though

 

yes, as long as you have 2 available pulse width outputs.

or you can just use c02 if u dont have avail pwm's

 

I use the controller Fueltech

FuelTech's BoostController is a multi-stage equipment which precisely manages up to 6 stages of boost and an extra launch stage, allowing the eficient and precise traction control for cars and motorbikes. It works controlling the top end wastegate pressure an it's possible to determine a dual ramp turbo pressure growth to set a smoothly turbo load at shifting, turning the engine's power generation ideal for the traction levels.
To work with high boost levels in racing applications, the BoostController is able to work together with a CO2 reservoir, keeping the appropriate pressure and traction controls.

Functions:
- Wastegate's Top End Boost Controller
- 6 Stages of Boost and 1 Launch Stage
- Sequential and Circuit Modes
- Boost+ and Boost- keys to instantly boost increase or decrease
- Dual Ramp Boost Growth Control per Stage
- Dual Pressure Control Solenoids Switch
- Wastegate Boost Control by pressurization or by CO2 reservoir for quick and precise response
- 87psi Integrated Pressure Sensor with 0,145psi resolution
- No computer required for operation

 

^^ That is just like using an NLR AMS-1000

here you go, another thread on this co2 stuff. read the whole thread cause the drawing i did has the ports marked incorrectly.
