I figured out how a reid vavle works today, I was getting confused because the picture in the book I was looking at sucked. It's just a flap. anybody have any real-life pictures of them? I can't figure out how to hinge it, maybe just use thin metal?

 

sounds nifty but with sucha built motor planned why not just run a nice sized t3/t4....originality is cool but think its going limit performance.

 

You mean like reed valves out of a 2 stroke? I have carbon fiber ones in my Banshee.

 

ya, like in a 2 stroke. is your banshee a bike?

hotrex, you just don't want my car to be soo much cooler than yours. this isn't just about originality, it's about the power band.

 

A Yamaha Banshee is a 4-wheeler. 350cc 2stroke twin cylinder. (107mph top speed) Hotrex is right, don't go crazy with dumping lots of money into this thing. I mean I spent under $350 on mine and it was only going on a d-series. You have to be prepared that it might not work and you have to throw it in the trash.

 

I'm already crazy on this thing. I've decided that I'm going to go with the 2 air filter design so that t1 isn't restricting t2 and so I can pull off both my headlights and put air filters in them when I drag race. There are only 3 things I need to figure out before the planning stages are done:
-how to do the bypass into t2
-where I'm going to put it inside the engine bay
-how I'm going to make the anti reversion vavles.

whitey, what is your idea with a custom manifold so that I don't have a turbo attached to a dp of another one? could you put your paint skills into action for me?

 

what im saying is your feeding a 14b then a t3 60/03? your still gonna need a big turbo to push the cfm

 

no, the 14b feeds a t4, I don't know what ar yet, still don't have either of them. what do you mean? the 14b is for fast response, once it hits 6 psi then the t4 takes over and whoops some ***.

 

Are you saying that you want the 14b to not have anymore exhaust? It sounds like to want to have the exhaust flow switch from one to another, not sequentially.

After thinking about this one for a few days, it really isn't that hard, The only things that has me thinking is the amount of CFM you can flow through one wastegate. I think you might need to look at two wastegates to feed the T4. This is where the math comes into play...

 

I'm trying to figure out how I can get some sort of bypass worked out with a big hole to go from teh mani to the t4. It may not be supra sequential, but it's sequential by definition since one turbo follows the next. the t4 is getting exhaust all the time, it's the 14b that gets cut off.
