twin turbo / supercharge

Well, I love my 540 but it needs more power. Anyone have a line on a pre-fabbed TT kit for an e34 540?

I'd really prefer to go TT but supercharging will do if nothing else is out there. I havent found anything yet, anyone with any info would be appreciated.

turbo maybe, twin though is gonna be a lot of calling to companies who might be able to fabricate something for you.

I have yet to hear of an aftermarket twin turbo kit for a BMW. And a twin turbo would nto be easy to fabricate or tune.

But if you can pull it off, ultimate baller status.

education time: (for me not you) What kind of engine does the car that you want to tt have in it?

If you have a v engine then a tt, is feasible and not too difficult to fab. The only problem is that you are looking for bolt on and not fabbed. On a v engine you can have the turbos come clean off the headers and the turbos will be fed by each side of the engine. This way you can run smaller turbos that will spool faster, then from the turbos run it to a fmic on and then onto the engine.

If you have an inline engine then doing a tt is not worth it, I would do a slightly larger single snail. Because it is running off all the cylinders then it should spool within a decent amount of time, especially if running a remotely low amount of boost.

Spool shouldn't be a problem. That can be affected by how much power he wants versus the sizing of the turbo. He has a v8 so I udnerstand how you are saying to put a turbo on each side. But this is just the same as puttign two turbos next to each other on an i6, each having 3 cylinders.

I'm sure space is a big problem for his v8.

The reason you wouldn't do tt on an inline engine is the header. With a v8 there are 2 headers which makes it easier to have tt, on an inlline there is only one header so doing two turbos would be very difficult because you would have to split the header in two sections.


Side note: and Idea I have always had is to have a smaller turbo feeding a larger turbo. In theory I believe that it would make power in lower rev range because of the efficiency of the small turbo and also higher in the rev range because of the bigger turbo. I have no idea how it would be plumbed but if I could figure it out I think it would be badass. Anyway, all that info had absolutely nothing to do with what I think he should do with his car.

I think on v engines it is easier to have a tt setup because then you don't have to plumb the two headers together. Of course that is just my opinion and no opinion is better than any other.

You can easily split up the turbo manifold on a i6 into two and have them feed into two turbos. But that's just ridiciulous.


I just logged back on here because I remembered a "mass produced" twin turbo e34 motor. Alpina made biturbo e34's. Try and google some info on those.

boostinsixtwintturbo is an unknown quantity at this point
one your side note, about one turbo being smaller to give good torque in the lower rpm range and use a bigger turbo for higher horsepower?.... well heres the problem..... its been done, but with both turbines being the same size..why?..... becuase its very very complicated to design a sequential setup in your back yard, you need valves to "hold" compressed air for the first stage turbine so it can build boost, and then you have to figure out how to desing the valve to open at a predetermine boost , to prespool the second turbine, and then they both have to spool together to get maximum effeciency and gain maximum hp. The RX7, and the supra, subaru legacy GT have that setup to reduce lag.
So.... if you were to use a small one and then a big one, it wont work,you would have to design a system to which only the small turbine would build boost for low rpm, and then basically shut it off after a determined boost, becuase if you were to combine both different size turbines, you will have conflicting cfm flows due to different size turbines and compressor wheels. Basically the second turbine will out spin the smaller turbine and push it beyond effeiciency range and now you will creat enormous heat and no power and also risk of blowing the smaller turbine, and making no power.

So back to the topic... The easy route, would be just getting the blower. And youll be happy with the hp gains.

Fuck it. I'm ordering a nitrous kit for the car. =P Good old 150 shot of nos. I dont street race every day of the week, so it'll work just as well. Less wear and tear in the long run.

Hey guys! New to the forum so I don't want to sound smug but if I'm not mistaken, the supera twin turbo's were "sequential" setups! Coming from a VR6 turbo background I've seen lots of these guys (mostly in the rearview) around! Although most supera guys will scrap that setup right away for a single honker due to the fact that if your running enough fuel to keep from detonating under boost you should have more than enough EGT to build boost rather quickly! And if that's not quick enough I would go with a 50 or 75 wet shot to get the egt's up and that will spool it right fast! Thats what I had to do on my last VR buildup, worked like someone lit a rocket under your ass!:
Correct me if I'm mistaken on this!

TT is goingto have faster spool and more overall boost then a single snail on a v configured motor as you can get the same volume of air at lower spool speeds then a single large turbo will.

All depends on the trim and size of your impeller, as well as the type of bearing cartridge. My last foray was a turbonetics ceramic ball bearing variant. You could just touch that impeller with your finger and the sob would spin for 2min cold! It was huge so it did take a while with only 2.8 little liters pushing the EGT's but it moved MASSIVE Amounts of CFM! 5" intake tubes, straight 4 1/2 exhaust. But like you said on a V config it does make a lot of sense to go with the TT setup due to the better flow charactaristics of keeping the individual banks separated on the exhaust side of things! Plus lets not forget that it looks just plain SICK!!
