alright, twin turbo man will help kyle become sequential turbo boy. We will fight crime.

I found a map sensor on the shelf in my automotive class, and since I don't fully understand a reid or rotary valve I think I'll use the map sensor idea. It was kind of like a trap door. I've got to go, I'll be back in 15 and in 30 I'll have my plan drawn up in paint.

Honda16hb

that's the basic plan. I didn't draw the bypass for from the mani to the big turbo, but you can pretend it's there.

Don't connect the downpipe to the downpipe of another. A custom manifold is necessary. You need 2 actuators, one in the manifold and one after the one turbo in the charge pipe.

I understand the charge pipe one, that's where I was going to put that maf trap door one, I don't know what you're saying with the other one. which turbo will the manifold one block? my plan is to use the ac bracket holes on the block to make a bracket to support the second turbo, and have a one way valve in the exhaust before the second turbo and after the first, in the dp of the first so to say.

for future reference we'll call the smaller first turbo t1 and the bigger second turbo t2.

Answer these questions:

1. Are you connecting t2 to the downpipe of t1?

2. How are you going to regulate the exhaust flow from one turbo to the other?

3. Do you think a MAF trap door will stop 4 to 8psi? Remember if boost is pushing past the seal and spinning the turbo thats not in use, it will be spinning the wrong way and when it is finally in use the change in direction will kill the bearings.

4. What size turbos are you going to use?

5. What motor is this going on?

Kyle, I'm about six months ahead of you. I'll post pics and a write up when I'm done.

Reddy

Just post pics of how you did your manifold and what actuators your using. Unless your cheating and just bought an RX-7 setup

he's either joking or holding out on his hmt brothers, I think it's the first one

1. Are you connecting t2 to the downpipe of t1?
yes, with a bracket to support t2 so nothing breaks off

2. How are you going to regulate the exhaust flow from one turbo to the other?
some sort of bypass valve before t1 to go into t2, still need to figure out how, and a wg in front of t2

3. Do you think a MAF trap door will stop 4 to 8psi? Remember if boost is pushing past the seal and spinning the turbo thats not in use, it will be spinning the wrong way and when it is finally in use the change in direction will kill the bearings.
I hope it will stop alot of psi, do you have any better suggestions? I could make a nice seat for the door and a high temp rubber seal

4. What size turbos are you going to use?
t1=either 14b or t25 t2=t4

5. What motor is this going on?
LS/VTEC forged rods and pistons pinned sleeves (not yet built, waiting on block and lots of money; the block is coming from bambooseven and the money is coming from magic)

Im being a bitch, I'll show you all when its done.

since that's going to be never just show me your progress so far. there is a quote function, I just neglected to use it due to the complexity of my reply.
