Could you use something like a synchronic BOV? I'm not too familiar with SC bypass valves as I am a turbo guy myself.

That's why i got the forged bypass valve. It comes with 3 springs and 2 washers to help change spring tension. I put the hardest spring in there with both washers and still the same thing.

I'm not to familiar with turbo bypass valves. I saw on youtube what they do, Danny is going to a shop and we will see if they have anything. But again I'm not going to do too much (spend more money) because sam is working on it.

Can you adjust hard/soft setting on that bpv?

You cant adjust the spring much, maybe in truning the bypas valve cover one turn for softer. but the spacers are in there to make it harder.

I was reading a Supercharged Ford Mustang Forum and they were having the same fluttering bypass problem. The solution was a larger bypass valve, one that can move more air or adding two bypass valves.

Sam did mention doing 2 bypass valves, but I havent had time to do that so. Did they add 2 bypass valves connected together or two in series (one closer to the supercharger and one further down)? I'll give this a try if its together since I now have 2 bypass valves.

I mentioned the HKS valve earlier. I understand probably not wanting to spend more but if you go to a pull type don't go and get some immitation.

Here's how it works. The SSQV is a pull type with 2 valves, one for response and one for high pressure relief.

Under boost (the purple area), the boost is always pushing on the back of the valve keeping it closed. It's impossible to leak since the valve is on the discharge side, not against the charge pipe.

Under light vaccuum/low boost operation the small valve in the ceter will actuate giving you a senstive small type valve.

Under high vaccuum/boost the largerand smaller valve will open together.

If I remeber these are rated around 500HP applications for one. They make different fittings for sound and recirculation. On the older post I also linked Turbosmart who makes lots of adapters. The push type you got work good too if you can size and spring it right, so not trying to knock your choice at all. I just found the HKS was always the least hassle on my turbo cars. Hope that helps if you decide to go that way. Good luck. Bad *** set up :tup:

cool. Yeah I'm not spending more. I just had a little free time as Sam is hard at work for Sema. I'm going to sit back and wait for him to come up with a solution now, which is hopefully in a week or two. I'm going to get a few more runs and send to sam and then dyno in a bout a week.

Took her out tonight... and all I can say is Holy COW. Its nuts how much this car does now. I did a couple of pulls and didnt realize i was already hitting 100 on the on ramp. I braked her down but its amazing how quick this will get there. Got a couple of video efuskay will post up later.

nice!

I can vouch for that. I'm working on pulling the vids off the Flip cam. Looks like it's slow going right now, but I'll get it done, and I'll post them up soon... :)

P.S. I tried to hold the camera as steady as I could, but all that torque made it quite challenging.

Ok here are a few vids... cops were everywhere... lol

Nice man. Keep the videos coming!
I'm sorry if I missed this but have you dyno'ed the car yet?

Not yet. I'm getting it broke in a few weeks before doing that. Maybe next week I'll have a dyno. I'm doing pulls and checking hoses and for leaks.
