thats just twins. not sequential. i can do twins but i am wondering if there is an easy way to reduce lag by spooling up one sooner than the other.

I am just looking for anything that may help. There does not seem to be a lot of information out there on the seqential set-ups, but I'm still surfing for something relative to what you wan to do.

Is it me or does that picture look a lot like a female reproductive system?

Most of the searches I looked into were from the ricer crowd.
RX7 sequential is mentioned often, a Japan only model I think.

It's definitely sound and a good thought for increased boost at lower RPM's over giggle gas. 99% of the RXt and Supra crowd remove the sequential setup due to its incredibly complex setup and lack of upgrade potential. Toyota or Mazda did not have to go to the Einstein level of design but they had the masses in mind not the gearheads. Check this link for a really good layout of the Toyota setup.

Now that right there would do it. Same concept I guess as you had Jim. I would see that the intake opening time on the second turbo may need to slightly lag the exhaust in order for it to spool up properly and it not back feed the intake pressure until it does spool up. The counter-acting forces on both rotors could cause the second turbo to stall.


Now Jim, this wouldn't happen to be a life sized reinactment and you are trying to find ways to have more "power" would it?

How about this as a "valve" - available in 2.5" - 3.5" sizes - Electronic cutout.


It's made to be flanged to the end of a three-screw setup, but I don't see why it wouldn't work mid-pipe? Then you wouldn't have the 90 degree turn like a wastegate would make you live with.
