[s-cars] Urs MRC stg 2...What wg spring?

[Dave Tremblay]

Bob,

 

i tried today the oem wastegate spring and max psi in 3,4,5 gear was a rock steady 20psi at 6 turns on the wastegate! 12.4 afr wot on the wideband. Pulls nice.

 

The reason i cranked to 6 was that i didnt get at all above 20 with 3-4 turns. Looks like the n75 does the job, but still 2-3 psi off. Nothing restrics flow on the exhaust side, system as no cats on it.

 

Dave
