what wastegate are you running for about 14-18psi or 400hp on a gsr?

im trying to figure out if the tial 38mm ok at that boost level with no to very little boost creep. i also understand that the type of turbo manifold will determine how much boost creep you will see. thanks

 

i don't have one but my buddie does and he put down 430whp on 17psi, piston and rod gsr, he had a mini ram and at 11psi on the gate it was creeping to 19psi by 7200 with a single 38, he ended up doing twin 38's to slove it

 

I had a 38mm WG on my Nuekin equal lenth and it creeped like H3LL. (7psi spring creep to 15psi) But then I went to a 44mm and it holds good.

same thing happened to me.... 13lb spring on piston/rod gsr with mini ram... was creeping to almost 20psi with the 38mm.... swapped it out for a 44mm and made 437whp on 20psi.... get the 44mm, and you won't have to second guess

also ran a sc61 on my fully built ls... ramhorn with 38mm and it held fine...

get the 44mm

 

Thanks for the info guys. looks like ill be getting the 44mm wastegate. is there any disadvantage to running a 44mm compared to running a 38mm? would the 44mm WG work on spoolin performance Quick4AC manifold without any modifications to it?

it will work on the sp manifold if its got a 44mm flange on it, or you can have one welded on like i did... there is NO disadvantage in running the 44mm except the price.. lol 44mm is easier to take on and off and flows WAY better... good luck with it
