How bad is it to boost without BOV ?
Hi everybody,
I built a really cheap turbo setup on my miata because I got the car for really cheap and just wanned to have a little bit more fun with it.
It,s no my first turbo setup but my first without BOV, I was wondering how bad it was on the turbo?
I took a turbo from a saab 9-5 and running about 8psi. I know surging is not good but I,ve seen turbo setup without BOV before so is there anyone that already tried it?
Thanks!

Yeah I am real helpful. Nice negative props. None of which came from me.
If you want serious answers ask serious questions.
Run no bov on turbo? I'd say it's fine as long as you don't run more than 3 psi.

This is the kind of info that interests me. Thanks for that. My thread was not about if it is good or not to run without blow off valve. As I explained, i am temporarly running without one and was just asking how bad that could be.
I dont know why people like to bash so much, If you dont want to answer, just dont, you dont HAVE to.
Thanks for understanding

but no, your car won't burn up in vodka fire if you run without one. But there's no reason you can't just do it all right the first time.

I will try to find a used wideband in the classified. I retarded my ignition timing to 4 deg instead of 10deg. Is there anything else suggested for timing? From what I understand the ignition box are useful only for the earlier generations of miata, am I right? (Because the 90-93 has the cam angle sensor)
Thanks
Thanks

By retarding your ignition to 4 degrees, you are preventing knock at peak power, but you sacrifice power everywhere else. Get a standalone, control your timing, stop being a noob, and stop posting.

Can we get pics of your setup? Interested to see what a turbo setup on stock ECU with no timing control at all and no BOV looks like.
