I don't feel like looking up the gay-*** conversion table, just ******* tell me or I'm going to kick your ***...please.


38kpa is the magic #. I need to order a ***** 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.

 

so should I get an 8psi BOV spring, or something firmer? I'm pretty firm right now.

 

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 **** 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.

 

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.

 

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.

 

ok...then order a softer one, I don't care...go for what we know will work the first time because if I don't make it to Hallett with this car I'm going to cry.


yes, my turbine is too big and compression is too low.

 

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

 

lawlin

 

I didn't know what "lawlin" was so I looked it up.

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.

 

Saved for posterity.

 

Better to go with too little. There's nothing wrong with it leaking at idle, just put a filter on the discharge port. Quiets it down a tad at the same time.

 

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