Re:sequential turbo
the thing to remember with butterfly valves is that exhaust is hot, so they will expand, and exhaust is dirty, so they might get locked open or shut.
I'm officially putting this idea on hold for the time being. I lack the fabrication skills and money to git r done, I'm just going to focus on getting my LS/VTEC single turbo done right now. |

Re:sequential turbo
you shouldn't be jumping to conclusions, I'm going to try this later, once I have more experience with turbo and everything, I'm still crazy.

Check into the reed valves that two stroke motocross bikes use.
Might be adaptable in some way. Edit: May be rob some of the parts off some one's RX7 system that they took off.

if you seriousely dont believe that you cant connect a turbo to a downpipe than you should not even be giving advice on turbo chargomg what so ever. obviousely you dont have a clue what your talking about and have very little experience with turbo set ups and engines in general for that matter. anyone with a basic understanding of how a turbo set up works would knw 100% that it can be done with very little effort. anybody with that same basic knowledge and the ability to weld would be able to attach a turbo to a downpipe in under an hour. if you already know you dont know what your talking about then dont advice. also i wouldnt recomend that you do any work to any cars you arnt prepared to scrap because not only do you not have a clue but the fact that you think you know enough to start giving advice to people on forums is evidence that everything you think you know about engines and turbocharging could not be farther from reality. |

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.
chances are you dont even own a yamaha banshee lmao. Because if you did you would probably know that they are not all 350cc. Learn how to use google and you wont have to throw your turbo setups in the trash anymore. How much have you really soent on your setup? You have been caught talkin out your ass 3 times already in the ten minutes ive been reading so im willing to bet you soent more than 350 just paying a mechanic to bolt the turbo on for you. |

Looks like this Krystian only signed up to roast this guy. lmfao.
Anyways, I do have something to contribute here. I've been doing it safe with my turbo setup on my saab, but now it's time to make some HP. At first my plan was to just get two small turbos and run one per cylinder pair (1/4 and 2/3 in the B235's case). It'd be cheaper than a bigger twinscroll garrett and just fun to do. But.... what if I put a valve after one turbo's exhaust to disable it and link the two manifolds together at first to spool one turbo quickly and then separate them again in the upper range. aka parallel sequential just like the Supra/RX7/Subaru boxer twin except id keep the turbos on their own cylinder pairs. I drew it out in the attached image. As for controlling the valves... -bypass would be normally open -high end turbo shut off would be normally closed -check valve on pressure side of high end turbo takes care of it self. -Once the low end turbo reaches 75% of its max boost, the shut off valve would open. This creates a blending region. -close the bypass shortly there after. Thoughts? Is it worth it to keep the turbos separate? I could just throw all the cylinders together, have two turbo mounts and have a shut off after one turbo. |
