Hi everyone, I have been thinking about if this would work ok on my car as something different.
Basically this idea comes from those tractor pulling engines where they put the outlet of the first turbo onto the inlet of the next one and they are stacked up like that.
So say the first turbo turns 0psi to 10psi, then the 2nd turbo pushes the 10psi up to 20psi and so on.
I know this works with larger turbos on the tractor pulling engines, I was just thinking if it would be worth trying to stack 2 stock turbos on my FC, as my turbo has been recently rebuilt :)
This is what it looks like:

wow..... that looks mint!! compressing compressed air..... I like it, but not sure how the old rotary would fair?? I supose you could use 2 smaller turbos to get the same as a large turbo, but then it would probably be big money??

Well im sure I can aquire a stock turbo, I still have mine attached to the car hehe, It will just mean that I can get the same boost as I would with a larger single, its just an idea as I havn\'t seen it done before on a rotary :) Althought I know you can get a twin turbo Rmagic FC kit with 2 smaller turbos.
I have found out that this is called \'compounding\' turbos :)
Here is a video of some, seems that they are on diesels mainly

They are explaining that the smaller turbo spools quicker meaning that the 2nd turbo spooler quicker due to the extra boost :)
I guess thinking about it, the issue might be the heat generated from the first turbo being fed into the 2nd turbo, compressing the air makes it hot to start off with, so...hmmm still thinking about this lol sounds like a good idea.
I could just bolt a GT4088 onto the car like my plan currently is lol :)
This is like the idea of compound steam engines - the exhaust gas drives one turbo, and the exhausted gas from that drives the next one. That turbo will have less energy, but it get first crack at compressing the air, then the first turbo on the exhaust side get\'s the weakly compressed air to really work it over. I can see it would work, but I can\'t help thinking that you\'d need to pay some attention to the size of the exhaust and compressor housings - the turbo\'s would be quite odd matches to make this work.
For instance the 2nd turbo on the exhaust side won\'t have much energy - so would need a turbine sized to make the most of the now slower moving air - it would need a fairly efficient compressor.
i thought u wanted to keep single hence u got fc?!
hows about a super turbo?
supercharger for low revs then a big tub for the latter?
else get something like T04Z size with a small exhaust housing?
what exactly are u aiming for? drag car or track? either way the suspension would be different for different applications so u cant go too extreme on either sides. (something to think about?)
ooo, just a though, how about running a Vortex supercharger off the pullys, feeding in to your single tubby?? you would have the same affect as above, but you would only be relying on the exhaust to spin up 1 charger & it is still getting air forced in to it ;)

Freaky, I was pondering this on my drive up to boro last weekend after Jono mentioned his little project including a small turbo. Sounds like a nice idea but if your going to that extreme why not just a single per rotor. :D Then again I imagine you can have a lagless setup with that.
guy in that video says turban instead of turbine lol
The issue that you have with that setup is that the first turbo\'s spool is affected by the fact that it has to force the second one to spin in a similar way to the non-sequential twin setup on the FD3. It would be very tricky to setup and get working correctly.
A lot of big, torquey, low revving diesel engines also dont have an intercooler - you would need to plumb one in to cope with cooling the charge from both turbos.
I think when you get down to it it\'s going to be difficult, as is the case with anything not tried before - are you ready to be fraustrated and cry when it wont do what you want it to do - or be a sensible wimp and go for something tried and tested?:yes
