I have recently changed my remote waste gate, the waste gate was controlled by air injectors. I have switched from a RS200 original waste gate to a Progate 50.

My question is this;

If i do not achieve the same boost as i did before (i dont expect to as the progate is larger) can i increase the spring rating in the waste gate to try and compensate?

I would have liked to have had the air injectors mapped with the new waste gate but it is hard now as the company i used and trusted to map my home built engines several times have shut down.

Also, would there be any adverse affects changing springs i.e would the waste gate try to lift earlier than it may have before as the engine was trying to reach maximum boost?

If there is any mapping experts reading this your thoughts would be appreciated,

Thankyou

 

You could just run an additional bleed before the wastegate to compensate.. what management was it mapped on?

 

Its mapped on P8 with mountune ALS baby board, thats a good idea, i hadn't thought of that. On the Air injectors there is a hole in the end cap turbo side and a hole in the end cap waste gate side. I will open the hole up a bit on the waste gate side and see what happens.

I will also order another spring for the waste gate, i should be able to get it right with the combination of the two.

Thanks for your advice.

 

Don't open up the bleed on the air injectors.. PM.
