can't kill turkey and i'm stalling w/ dual bpv/bov

[Autox MSP]

I haven't seen any problems with the hi boost kit. I know 2 users in my area with that kit, other then blowing the pipes off occasionally they didn't have any problems witht he bpv.

 

[Mark94]

okay, then the ES piping is the calprit for their piss poor engineering. But for the rest of us, its not warrented.

Honestly, I'm not sure where his flaw is. I bought an injen intake to test also because I thought it was the ES intake as a whole that was the problem but it still stalled with the Injen in and the HKS recirced to the injen.

All I know is that the dual valves solved ALL my problems.

also would it be possible to buy a diff maf like a blow by that might not be affected by air passing it ?

If you could find one that has the same output as our stock one, it would work.

I don't really trust using our MAF as a blow-through, even though there is one guy here that hasn't had any problems with doing that yet.

The original prototype injen made had the same problem. It was on Spicy's car.

what about all those guys running the stock box? and ghetto rigging this set up ?

I don't *think* that there is anyone running the BOV/BPV setup with the stock airbox. Could be wrong about that though.

ok so im coming to the conclusion that it would be better to have a custom intake made for our cars the pic i posted above you can see how far my return hose goes , mine dumps litterly 2 inches befor the coupling at the turbo

on a 240sx, you can bolt on a MAF from a Mustang Cobra. Jwolf programs the ecu to read it.

Wonder if something similer can be done with the msp?

That's Custom MSP, he is the nice guy who volunteered to stop by my house to try to figure out what was wrong with my car.

I didn't trust that method either but his car ran like a champ though.

Ok, I don't think we can blame stalling on the Injen intake.

I too had stalling issues with the HKS bpv valve that came with my HiBoost FMIC. My stalling was completely fixed with a single Turbo XS H25 bpv and the stock vacuum tap from the wastegate tee. No fuss, no dual valves, no re-running vac lines, ZERO compressor surge. Doesn't make the "look at me" noise - all you hear is the turbo spooling and a subtle release of air when the bpv opens under heavy throttle.

I wish there was something like that. It may have saved me a lot of money trying to troubleshoot my problems but the MSP just seems so tempermental in terms of what it likes and dislikes.

Unfortunately, it doesn't seem to like much.

I can't see the pic because the link doesn't work for me, but yes, closer to the turbo is better.

Here is the thread that shows how I did the dual BPV, forgot to post it earlier when you asked about it:

What's up Glow. I think that is the valve that ES is now recommending and they said it does not stall with. Maybe the HKS is the culprit.

I didn't want to invest any more money by welding a new flange on and the cost of a new BOV so I tried the free alternative and it worked.

It could. MPI offers a 80mm maf and the MPI tuner can use it... it's not blow through, but just saying that something similar is already being done.

the valve hes talking about is about 160$$ you can get a adapter for hks flange im sure

I dunno what the major breakdown here is. The dual valve problem solves the surging on car. I worked a little bit with Mark94 on his HKS and nothing we tried got rid of the surge/stall. The dual valve worked out for him. Also with my Greddy type-s no matter what you do it will surge. Even on the loosest setting with the smaller spring removed and recirculated. The dual valved forge whatever it is, solves the stalling problem but won't remove the surge. If you truly want form over function then the bpv/bov is a good start. It doesn't look the cleanest (no offense 505zoom) but it is functional and it works which is what truly counts in the end.

actually jim wolf is in el cajon, outside of san diego. Im thinking of taking the ecu to him and see if he could do something.

None taken, I don't really care too much if something is unsightly, as long as it functions properly.

heres a thread with pics of my set up single bpv works fine
with return hose aprox 2 inches from turbo coupler

notorious the break down is that maf cars should not be vented , there is cheap alternatives . and any way you cut it a car will run richer if you vent it (maf cars) especially the richest car on earth the MSP

 

[Notorious]

Yes any car that uses a closed system maf will run richer vented I agree. But if you run 2 valves back into the intake to relieve surge you won't have to deal with that. If you can successfully run one open vent and one rerouted without a performance decrease, all the more power to you.

That intake looks good. How is the fanwash though?

You know what is wierd though? And I didn't notice this untill I got the WBo2, but the car runs insanely lean when you let off the gas... even with the BOV/BPV setup. Discreet said he noticed this as well.

The msp doesn't run rich ALL the time... only in open loop.
