My draw through turbo

[rubenski]

The one pictures looks verry alike the one i got with my cb gen4 efi package. Same colour and same model.

My ecu will controll boost.

Can anyone please explain something to me. On the 3 way solenoid one connection goes to the wastegate, another will go to the turbo boost pressure side, now the thrid connection has an air filter in it does this vent to atmosphere?
If so does it vent a small bit of boost to atmosphere or does it just connect the wastegate to atmosphere?
Hope that makes sense?

^^ not sure if this helps....it's how the Subaru's are run using a 3 port.

[advinnie]

Yes that helps a lot cheers
Now the big question is do I really need one, is it really worth it?
Any advice by the people who are using one?

I love mine, I can change from 14 to 30psi without getting out of the car. How are you planning to control the valve? Thats whats actually important here? Eboost street or eboost2? Or some other non Turbosmart product?

[advinnie]

This is what im looking at
https://ldperformance.co.uk/product/ele ... ontroller/
I'm planning on putting a switch in so I can have two different boost settings. One set to 8 ish psi for just driving around and the other setting at 14psi for fun times
I'm still reading up on what GAIN and DUTY CYCLE is

I like mine too. I still have to change my settings in Tuner Studio, but it works. Still waiting/hoping for Chip to do an idiots guide to making/programming his switch

Oh dang! I didn't know I was supposed to do that! I have two weeks off work starting this evening. Maybe I'll get some time to break it down a bit. It wasn't too tough!

FYI,

I contacted Mark @ cb to ask if i could something like that, a switch for 2 boost settings.

Its a no go. I have the "single boost" valve and with that i can have boost control trough the wastegate.
What IS possible is that i make 2 separate maps, one for low boost and one for high boost.

Switching between the two would involve hooking up the laptop and going from 1 map to another.

No biggie for me. I think about buying one of those windows based (not android) computers with touchscreen. Not like a laptop, much smaller.

For any of you guys running ms3 you can put in a 12 position switch to do variable boost control on my drag car i have it set to just above wastegate ~16psi on 0 and when its turned upto 11 it goes to 43 psi (used to be 8psi to about 30 with a weaker spring)

the instructions I used are here https://sites.google.com/site/sloppywik ... al-a-boost

Nice resource! I used a 2 pole 4 or 5 position switch for mine. I just had to modify the switch so that it would work with 0-5v.

I just get out and turn the knob. Well....I did....not so much now!

[advinnie]

Right today, now my A/F ratio gauge is back up and running I fitted my 14 psi wastegate spring and found something I've not come across as of yet. What's happening is that in getting a spike to 15psi before it does settle down to the target 14psi but as the rpm's keep climbing the boost pressure is falling slowly down to 12 psi it will not maintain the 14psi boost target. Now when I had the 12 psi wastegate spring in I would get a spike to 13 psi and it would maintain a constant 11.8 psi of boost no matter high much higher the rpm's went. So why am I not able to maintain the 14psi?

[buguy]

Well if all you did was change the spring....that kind of narrows it down. I suppose it could be the wastegate itself, but most likely it's just the spring.

[advinnie]

I've already removed and refitted the spring but it's made no difference, I still jump up to 15 psi before it falls and settles at 14 for a few seconds then slowly they boost falls off as rpm increase I will have another play with it tomorrow.
