I took a 3/8" socket entension and hit it with a hammer. I indented mine a little less than 1/4".

With all that money spent, just go grab a TiAL or Forge or something.

Just remove the BPV and block it off for tuning until you can buy another one.

I personally don't like Perrin Products, but you seem to have all of their stuff already so why not. I think the APS or the Forge would be a better choice.

Default On pump...

I want to say you might see low 80% duty cycles on your 740cc injectors with that setup on the street. Meth will just drop that...or if you add more boost make it break even.

Race gas will change the situation with more boost but I don't think you will max the injectors.

740's can support some fairly serious power.

Sounds like a great setup.

I run an APS BOV on my 20G setup and it seems to hold just fine. If I were you I would get something you can adjust without a hammer.

I do love adjustability.

you may need a boost control solenoid for that much psi. the GM or Grainger will be suitable.

I know this isn't a classified forum but i am located in storrs, ct only 25 minutes from XX and am returning my car to stock this afternoon and will have a turbosmart dual port bov for sale. I bought it at XX in April so it has only been used for approx: 4k miles. Its in excellent shape and have everything it came with whether you want to run 100% atmospheric, 50/50, or completely recirculating. New plus tax your looking at $290 and i would sell mine for much less and would meet up before you go for the tune if you would want to. pm if you are interested. good luck with the tune either way thats an awesome list of mods you have.

here's a thought...ask your tuner what he recommends.

- He will tell you if you need a BOV...which you don't...I ran 28psi on a 30R with the stocker.
- He will tell you if your 740's will be enough...which they will be
- He will tell you if you need another boost controller or boost solenoid....which you won't, the Protuner software will tune the boost just fine.
