you can vent a bypass valve to atmosphere and a get that whooshing sound. its a bypass valve because in vacuum its open allowing air from the spinning supercharger to escape. it closes when you give enough throttle and load to reach 0 vacuum so then you build boost.

blowoff valves are always closed until theres a pressure difference when you shift and then it opens to release the air before its forced backwards towards the turbo or supercharger

the bypass valve on this kit is not recirculated, it is vented to atmosphere with just a small K&N filter on it to catch debris because it remains open while idling/ in vacuum

Great explanation!!

Thanks, didn't know it worked like this.


So, the difference between a bypass valve and a BOV is that the BPV is always open until 0 vacuum is achieved and then it closes. In contrast, a BOV is always closed until throttle lift when air pressure will open it?


I had thought the difference between a BPV and a BOV was that the BPV could never vent to atmosphere, just recirculate but BOV's could either full dump to atmosphere or do 50/50 or similar.

I dont believe @F1point4 is running a BOV, maybe he could chime in on this.

I can also confirm the woosh is indeed there with the vortech kit, installed my kit earlier this week and it's definitely noticeable, it's not as pronounced as a bov but you can hear it. I'm running the new blower with the 9psi pulley included in the kit with perrins tune.

Maybe I just haven't heard mine when I was on the old blower. still haven't drove my car after reinstalling the new upgrade blower and more boost.

I am using a blowoff valve. It does come with the kit. With the upgraded blower it sounds like the Blowoff valve is working more than before.

So its not a Bosch BPV valve, its something different?

#$%^&*)(!@

dear god, thank you

I steer with the throttle 100%

I came home feeling like $6M dollar man, superman and my last name may as well be Schumacher

the car is mutha farking awesome, I cant provide you amore honest review
I am not lying, this rocks @Sivtec rode with me today, seeking comments

P&L makes it go faster,if you track your car, want that extra power, hands down, winner
sold

its faster, than before, period, on the track, drove really good and am happy with my self, my car, and my tests

Perrin sent me a new tune file that did wonders with the header, he tunes very safe, my god does that work great on the track,

Was able to reproduce fuel issues on left hand turns over and over anytime I was a 3/4 tank, NO ISSUES when FULL, data log captured it and will be studied

Vortech performed FLAWLESSly in the heat, drove it at 10/10 today. no issues.

did I mention its now officially farking fast?

a second person who was just in another Turbo car commented on my power delivery and they seemed to like mine alot too, but I rather them express their review in their own words

Temps were hot, but within their operating range oil, sc, water. OE fuel, oe rad, the money saved is buying more tires, gonna need more
curious if higher fuel pressure mitigates what I am feeling on hard left drifts on full throttle..does aftermarket pump solve this?

fastness = tires
great day at Firebird. no pics, spaced on video, sorry
having too much fun..

I apologize for my ignorance. Rechecking the manual it is a bypass valve. According to those here, that is different from a Blow-off valve.

I'm not sure where it originates. I do know the Vortech Part number is

8D001-004

Googling says it can handle 0-10 psi. It does vent into atmosphere.

Gem,

Although that was hard to read, I'm glad you are enjoying it. Chris mentioned getting a new tune soon from Perrin, I'm looking forward to it now

Any updates on how you were able to check SC fluid temps? Thanks

well the manual states its a bpv but the actual part included says bov, I guess it could be a bit confusing. Mine came with a turbosmart.

This is the part that it came with.

Gem,
Also curious to see how much power you're gonna put down with the header. Definitely gaining interest on the P&L header now myself.

[PhastekSport]

Glad to hear your feedback Gem. I've been to that track before.

Anyways I think we're getting sent the new tune early this week.

This is interesting. The picture below shows what we got down here in Houston. Looks different than what was linked. Very interesting...

I appreciate your concerns, and feel I have worried you over nothing. What I observed last weekend at the track, needs to be written of as a user overfill error.

yep, I have a temp gauge on my sc, so you wont need one @Sivtec played passenger/pilot and checked almost every lap, thanks

you have nothing to worry about, I never reached the temps that would be cause for alarm, close but not quite, I assure you, had a BLAST and everything was awesome.

SC Temps stayed below the prescribed limit during my runs, phx heat was 93-95 today, ambient a few degrees hotter at the track. I drove it trying to break it

I drove it almost ruthlessly, pushing it

Its hot where I live but nothing to be worried about, you dont need to buy a gauge, no need for it what so ever. promise. It is fine, in speaking with Vortechs R&D, its temps are exactly what they expected it to be in my climate, and so 'normal'

when correct volume of fluid is used, they have engineered a solution thats FINE at the track in the heat. Period. tested, check boxed, done. nothing to learn here, but I DID ensure I was not over filled, and checked my level 10 times till I was sure the top most thatch showed no oil , but all other thatches show oil, so I ran it 1mm low from full, PERFECT. I'm waiting to cool it off to drain and 'see', and expect it to look like it was when I filled it yesterday.
