how much vacuum does my car pull at idle in psi?
I don't feel like looking up the gay-ass conversion table, just fucking tell me or I'm going to kick your ass...please.
38kpa is the magic #. I need to order a penis pump...I mean blow off valve. |
Here you go douche, 38 kpa 5.511434044 psi, However, 100kpa is atmo. So technically you are in negative psi.... My head hurts.

Are you going with a Tial I assume? From what I've read you should go with the stiffest spring with it.
I personally have a Greddy Type R, so my shit is adjustable. |
I want it in inHg. My autometer gauge says my miata, idling is around 21.
|
Aren't you running a MAP-based ECU, Hustler? Hell, my BOV is open at idle.
|
Tim, I'm still emailing you. I don't want compressor surge of course. My gauge reads 222 or so at idle, 28inhg on decel. What do you recommend?
Yes, tial Q. |
You need the Pink spring. -12psi.

Trust me, you will not surge. If I lift when in boost, my logs show 8KPa which is the lowest the MAP sensor reads. That thing WILL open.

I'd recommend whatever TiAL recommends cause I have zero experience with their stuff. |
K, You've been emailed Tim. I'll go with pink.

FWIW, I had to modify/machine my old-style FM BOV to open sooner/have less spring pressure with the current twins. It's open at idle. Otherwise it'd compressor surge just going from 10inHG vac to 15inHg vac cruising.
But your .86 is going to be so laggy it won't matter. :p |

Get both springs??? They only cost like $15.

I got 2 full weekends to build yours stuffes. Plus an extra day off work due to Labor day. If he doesn't make it it won't be because of me. |

mine won't be....hopefully. However, I don't know if its better to go with too much or too little spring. I guess I'd rather it suck in dust rather than compressor surge.

Tial Q has discharge ports all around cause that's sooo cool right. But I agree nevertheless.

I'm thrilled to get this kit made in general, not so worried about the time...but man I'd love to drive at the 2-day event I already paid for last year, which I paid for and missed because my car wasn't done. lol Oh and seriously, you'll be in my intoxicated thoughts and Satanic prayers over my 4-day, Labor Day weekend on the party barge at Lake Travis. |
matt's rules for blow off valves:
1. get the one that flows the most. 2. use BOTH ports (so vac holds it closed at idle). 3. run it as loose as possible such that it doesn't quite leak. I've got my greddy type R installed just like this and it opens any time there's a positive pressure differential across it. it can even whistle a tune if I want. |
