trying to find out what size wastegate I should use?

lq4 stock bottom
317 cnc's
triple 12 cam
60# inj.

plain on 10 to 12# of boost what size should i run? 35mm 40mm 50mm or?

i can get a killer deal on a tial 35mm but dont know if its to small?

 

what size of turbo?

 

Whos kit?

Off hand I would say 50mm. Better to have too much gate than too little.

 

anything larger than a 62mm i would say at least a 45mm. im doing a tial 45 on mysetup with a s472

 

I'm new to this so i'm not sure I got the lingo down so bear with me

its a 73mm turbo the hot side has .96 a/r on it, I'm sure its a off brand turbo there is no name or model stamped into it I dont know any thing more about it

its a home grown kit that came with my truck when i bought it, its a rear mount setup (yeah I know) i want to get it installed and see what it does i'm really just hoping to make 500 to 600rwhp

 

Get a 50mm gate. The turbo smart pro gate 50 is nice.

 

whatever you do dont do a 35mm, its more likely to have boost creep at lower boost levels,

 

can you explain that?

 

larger turbos will i guess you say over power the wastegate, as in the wastegate cant let enough out to keep the turbo on a steady low boost level.

if you planned on doing boost that was higher and closer to the peak of efficiency range then id say a smaller gate would be ok

 

thanks for explaining that I follow what your saying
