how do i lower the psi on a 14b wastegate to run a lower amount of boost

 

so no 1 know any thing right?

 

the internal wastegate spring needs to be adjusted....or if you want more hp you can bend the actuator...but i suggest doing either of these to take it to a shop that knos how to work with 14b's

 

any 1 else

 

TO run lower boost,

Cut the Actuator, Thread each end and then take a bolt, pipe whatever and tap the inside, put the two pieces to gether and make the rod LONGER to lowr boost.

Longer rod will hold the WG FLapper open a little.

Read the FAQs and llok at the Turbo Projects on the openning page. People have done and posted about it.

What car/engine. I was going to lower mine. First few drives it sucked so I put backl to the stock 8 psi.

 

I used to have a problem with my 14B wastegate where it (since it was rigged to work with HF manifold.. the stock bolt holes do not line up) it would hold the wastegate flapper slightly open which is what you are describing.

It sucked ***. It shot my spool time all to hell and would leak boost.

The only *real* way to lower the boost pressure would be to modify the internal spring. cut a little bit off of it or something so it has less tension.

 

or just run the whole 8Psi. its not that much...

 

look dude, there's no good way to lower the boost of a wastegate can. you can make the rod longer but you're just propping the flapper open and that's just dumb. those wastegate cans suck anyway, just weld the flapper lever shut and use an external wastegate.

 

why dont you just use a carb spring?thats i was going to do.

 

hey i need reverse instructions...i bought my 14b and the guy said he bent the actuator so its at 10psi...i need it back at 8...should i just bend it back or let the guy at the shop do it?
