Wastegate Max Boost Without CO2?
Wastegate Max Boost Without CO2? I have been under the impression that you can only go slightly more than double the spring PSI on the gate. I was discussing this with a buddy of mine that owns a speed shop and he disagreed. He said that in their old turbo race car, they could build 30+ psi on a 7 psi spring and control the entire range without CO2.
Does this sound correct? It made sense that the more boost you make the harder you are pushing on the back of the wastegate which should keep it closed. I've been thinking about it all night and the only thing that I can come up with is that the boost ref port on the side of the WG has to be being messed with or not used at all.
What do you guys think?

As long as you have both ports hooked up, you can go at least 3x whatever spring you have in there on a decent brand waste gate.
Top port would go to the boost control solenoid, bottom port goes to the charge pipe.
< Done 35psi on 9lb spring on Tial 44mm.

I've seen seen a 4" outlet turbo, with a restrictive 3" exhaust (flowmaster) have 17psi of spring in a 50mm gate and would only make 7.5 psi boost.
Exhaust was replaced with a 3 1/2 " and freer flowing muffler and boost shot straight to 17 psi and spooled twice as fast.
in fact it went from not being able to make enough boost , too having trouble controlling to much boost lol !!
