Just curiious, another thing i pondered with my new build up was when do you upgrade wategates, and why would you upgrade? i never really saw a good explanation as to why and when to start thinking of going bigger, i just have a stadard 35mm Tial right now, but going for big hp.
also how do you knwo what springs top out at what psi with the boost controller
sorry if this sounds newbish , but i never really saw a post on this before.

 

I'm currently running the tial 35mmhp wastegate. Seems to work ok so far. Just need to work some bugs out of the boost controller.

 

isnt the HP a higbrid, like 35mm bottom and 38mm top?

 

I read in one post one reason to go larger is when running low street boost levels on a high hp potential engine/turbo setup. Meaning that a 500hp @24psi setup will have to evacuate/bypass a LOT more exhaust pressure when only running 12psi on the street.

 

Bump. . . also would a 1bar spring fit the standard 35mm tials?

 

DSM guys have been running two bar on the 35mm tial's for a while.. Your current setup should be fine.

 

cool , thnaks for the info

 

The 35mmhp is the hybrid one where it uses the 35mm base and 40mm top. ALso, i don't think the 1 bar spring will fit hte standard 35mm wastegate. If you really want, there's a tial 35mmhp in the clasified for like 210 i think. NOt too bad for the price and i have a 1.1 bar spring here i'll sell ya. Paul

 

so the highest you can go on the 35mm is the .8 bar?
im not lokoing to upgrade yet?

 

Yes, the highest is the .8bar.

 

so once thats on the boost controller how high of boost can you get with that low of a spring?

 

I'm somewhat in the same boat. Although I'm not looking for quite as much power, my goal is 400whp. What wastegate and spring do you recommend to use in conjunction with my Greddy Profec B boost controller? Thanks.
