hi any pics

 

Here's a picture of my Synapse. I am using a different spring in 'Pull' mode as well as using Port A only. I left Port B venting, but put a little filter on it. So far I don't have any partial throttle issues, no fluttering, no bucking, no nothing. I took my car to a road-course earlier last month and everything was phenomenal.

 

Any updates on your guys' DV's?

I am looking for a DV that has the driveability and noise control of a IX DV, but can hold up to 26psi leak-free.

This seems like a good option, although I see a lot of fluttering problems, has any of this been resolved?

 

interesting - I would think the pull type would be more sensitive since its vaccum related. But, I am no genius!

 

I installed this Dv today. I had this installed it in the pull style first and thought maybe I installed it wrong. The car was running worse then ever! I was having major idle issues when start up and major flutter issues during partial throttle. I installed it push style today. This was the best for my car with both port a and b hooked up. I have no flutter, no stalling issues at stop signs lol.. All i have to say is this thing is *****en. Once installed in push mode My booost jumped to over 30 psi when I was originally set to 26-27 psi. This thing is amazing and I would recommend this dv over any..

 

Where is everyone getting this experimental spring?

 

I just installed the experimental spring and flipped the valve to pull mode. I've got three turns of preload. Heading out to run some errands and will report back.

 

^^^keep us updated! I'm glad I found this thread, I just got my Synapse DV in the mail from No Limit 2 days ago. I will be using the Tial flange. I am swapping this for my Tial Q...driveability was terrible with it.

 

ok, pull mode with three turns of preload on the experimental spring and port A has waaaay less DV flutter at part throttle boost than push mode. Flutter is nearly non-existent. I can still induce some flutter if I try, but what flutter I can induce seems to cause much less bucking.

I'll probably try tweaking the preload a bit today and tomorrow to see if I can make it even better.

 

Got a little more daily driving in at lunch time. I can still get a bit of bucking, but much less than when setup in push mode, and with the current spring preload and using Port A, the buck occurs almost as the gauge crosses from boost to vacuum with steady throttle.

 

Ughhhh...This is what my Forge does ~4 - 6psi going up a hill in 6th gear around 3000 - 3500 rpm. If I downshift to 5th and keep the RPMs above 4500, I don't seem to get the bucking at all.

If I am on flat ground cruising at ~4 - 6psi I don't get the bucking / fluttering.

I wonder if I should install a stiffer spring ????

 

I don't think I can comment. I haven't tried the Synapse factory spring in pull mode yet. All I can say, if it helps, is that the experimental spring is softer than the factory spring.

 

where are you guys getting this experimental spring? I dont think it was answered anywhere

 

I would like to know more about this also...

 

I have the springs. Pm me if you want 1.

They're not very expensive....

I am still trying to find what i believe is the right spring.
