ATI blow off valve
ATI blow off valve Guys I'm running a 408ci..... F1R@ 15#... using the stock blow off valve that came with the P1SC. Under deceleration I'm blowing my plunbing off my TB. Is the Stock P1SC blow off to small? What are you guys running, what do you reccomend? Any help appreciated.
yea its most likely very small...when you decellerate with teh throttle shut..the blower is still moving a ton of air.
go with a vortech mondo or a ati race.
I bought a brand new mondo on ebay for about 120 bucks.

You have been helped
Get either the Vortech MONDO bypass -OR- An ATI Race Ready Bypass.
A quick internet search of either term will net you a place to buy one.
You will have to change your flange to mount one of these two.

This is the one I am running. And yes it sounds like a big *** portable air compressor leaking lots of air. If you click on the link in my sig you can see a small pic of the bpv.

Considering I've seen a hot street camaro with a big block, f3r, and a 4 port fuel system running an ATI-race blowoff valve, I think our friend running an F1R should be fine.

all of that air has to go somewhere...thats why you cant run a standard BOV on a centrifugal car...you really need to run a ATI or vortech type bypass valve.
the bypass valve is also open at idle...which will allow a smooth idle instead of some surging that can occur.
