non sequential conversion...
 
hi, does anyone have a non sequential conversion here? also how does the boost come on and does anyone have a non sequential conversion with a straight pipe? is there any turbo lag? how much boost do you guys get with your setup?

thanks for the info

Yeah I'm running my turbos non-sequential with a DP, MP, and CB. The boost will come on slower, no more nailing the throttle at 3000rpm at seeing full boost. There is more turbo lag, especially below 4000rpm. By 4000 i can usually get to at least 10-12psi, but it depends what gear your in. Since the boost builds slower, you dont see much boost at low rpm partly because your rpms climb much faster than your boost does. If you're in fifth gear you can get 10 psi at 3000 becouse your rpms dont climb as fast in fifth, but you still have to wait for it. I'm running about 12.5 psi.

I have one question regarding the non-sequential setup that I think might be helpful for others. I've noticed that with a highflow cat on my car(sequential) my boost would rise much faster at lower rpms when compared to the mp I have now. Knowing that in parallel the stock turbos have noticeably more lag at lower rpms, why does everyone recommend the mp over a highflow cat? From my personal experience I think that adding a little backpressure to the exhaust when running the stock turbos in parallel might be a good idea. It might lower the max hp a bit, but it should have noticeable benefits for every day driveability. Anyone ever try installing the two with parallel twins? Were there any benefits/disadvantages between the two??
