Looking for opinions on bov options for cars in 450-550whp range what are you using?

 

depends on how much boost you are running but I would guess any aftermarket bov would suffice.

 

Tial ?

 

30-35# on E85

 

Ron at RS Motors here in MN has just over 400 on his 9 and he has a completely stock motor, FMIC, turbo and BOV. I personally plan on getting mine into the 380-420 range and will use a 9 turbo and 9 BOV w/E85 and 1000cc injectors. The stock 9 BOV's are made VERY well

 

His crushed IX is leaking. I've suggested the Cobb BPV and Synapse DV. He will need something that's compact and fits it the stock location (VTA is not an option, he is still running MAF).

 

get a aps twin vent bov. problem solved and fits stock location Hey op are you in plano tx??

 

Only two bov's that are worth anything are the stock 9 or tial. Keep in mind one thing though. The stock 9 bov will taper pretty badly and will only hold about 21-28 psi by redline depending on whether or not it has been crushed. The Tial is the only bov that I will run.

Where they stopped making them and used as hard to find. No I'm in IL

 

im telling you get a used one off the forums i know of a 750+whp evo using aps to perfection and im 600whp no issues. you can get them used for like 100-200 range. Wow was not aware they stopped making them lol glad i got mine when i did over a year ago. Pick one up and you will be good to go for over 40psi if you so desired.

 

Tin foil hat?

 

500+hp here and my Synapse is holding perfectly...I'm running the new DV.
Previously I had on a dejon tools modded stock DV, and just switching bov's (nothing else changed) I held +2psi from peak all the way to the tail.

 

synapse dv or aps twin vent if you can find one

 

tial 50mm for me
