Turbo manifold design

Off topic but have you played with any kind of traction control?

I have been using Race Logic Traction Control since 2005.

I developed 13B specific cut patterns for RL and I sell the maps to people who buy systems off them for use on rotaries I have tested it at length and my system/programming is proven many rotary users and literally covered hundreds of thousadns of killometers ulike other BIG NAME ECU suppliers mine actually works and will not fuck your engine in true F1 style fuel cut (only way to do TC properly@!) some other makers have such issues with TC on rotaries that they fuck around with other inferior methods like electronic throttles LOL or spark cutting etc etc.

RICESP would be totally useless without TC

If you look on my web site I have one video where I do some testing at my local air port on about 18psi boost and there are patches of wet tarmac, you can hear the TC operating in 1st and 2nd gear. I have other video's where I am driving some cunts FD that I fitted my TC too and you can hear it working around the track in the slow 2nd gear corners, it sounds just like an F1 car *old F1 car lol*.

When I first started using RL TC I did about 30,000km testing on the first unit, I pulled down the engien to check eveything and the wear was nothing more than a car running without it fitted............. Its the best thing ever for a 2WD high powered car.

^ unbeaten to this day for a true genuine road FD on twin turbo's on hard compound road tires, I set a lap record with full fuel tank too lol ........ lots of people have tried to beat it with soft compound tires and gutted FD's non have ever got close. And I was not even trying too hard, not too bad for a "hack driver" imagine if I was racing for plastic trophys every weekend LOL.

Don't know yet. For one, I'm not sure what all the options are haha, and I haven't talked to Tom (the guy that's going to build it) about all that yet either, I just asked him if he'd build it for me. He has hand-built whole exhaust systems before and they're gorgeous. So I think he'll do just fine haha. And luckily he's local, so I'll just drive my car over there when I get back and start pulling out the turbo and manifold so he can get to work.

Anyway, I'd like to use a size similar to the pic I posted on the previous page, something large enough that I don't have to worry about it being restrictive. I'm not sure what sizes are offered in 321 though.

I know this is more than what you asked, I'm just excited about it haha.

Flow and angles n shit makes less difference when you are running higher and higher pressure ratio's, which lets face it you have to on any rotary due to its small capacity be it 2,3 or 4 rotors compared to what you have to work with in any decent reciprocating engine.

Same for pipe work sizes etc. IMHO I use the stock std 2.75" pipes in my rig and I say again make so much power that the car is almost un enjoyable as you just cant rev it out in 3rd gear or what ever cause you are just doing over 100mph in less than 2 seconds. < This fact is hard to convey to people who have not had a really fast car yet. Its so easy to get almost 600bhp out of a 13B its not funny and when you are there and you have it in a car of 2800lb or so then all this talk of intercoolers and manifolds and turbos A/R's etc will all seem academic to you............ you will know it when it happens

What ever all of you decide you WILL need water injection to make it durable *long term* like I have proven with RICESP, without it you can measure the life in minutes LOL

One thing I need to mention is that at this time I'm not interested in using race gas, so I won't be pushing any more than 20-25psi.

It's funny you mention all that, because I'm not so much looking for high HP, my main goal here is the quickest response I can get. What I'd love is to have the response of the stock twins but in a single turbo setup. I know that's pretty impossible, but if I can get at least somewhat close I'll be happy. If I get high HP out of it, that's cool. Honestly though, the altitude where I live robs us by 27% on a boosted car (I don't know how much on an NA but I can't even imagine), so the higher HP the better, but it's not my main concern. When I go back home to closer to sea level I can really tell how much my car is actually putting out. It's quite a difference, and it's WAY fun haha. Really though, I'm not sure if any of my setups have put out what they were supposed to, and I'm not sure if it's because of the altitude or what.

I am already using the FJO water injection kit. It's injected about half way between the IC and the intake elbow, JUST past the BOV. I'd heard of people (well, mainly you haha) injecting at the turbo, but I was wondering how much, if any, got stuck in the IC and never made it to the engine. I also figured since mine is injected anyway and not just sprayed, I wouldn't need the turbo to atomize it so I could put it pretty much wherever, but I still wanted to put it just past the IC instead of in the elbow. I'm not using it for more HP though, I'm only using it for protection of the engine. I'm using windshield wiper fluid...it's already mixed the same every time, so I don't have to worry about mixing up ratios (which I probably would lol). I was using just distilled water at first but it got cold enough pre-winter that it froze and burst my pressure sensor, so I moved to wiper fluid.
