I will do my best to upload as many pictures as I can. Our aftercooler design comes with a supercharger discharge manifold that bolts on to the supercharger exit path. The exit path then blows straight into our aftercooler. There is one rubber boot that seals these two manifolds and thats how we route the supercharger so there no psi loss.

sounds good... just let us all know when you do post em...

Ok so back to the twincharged thread...
I'm thinkin An M62 SC feeding into this Gintani W2A...
A 2876 turbo helping out going to a FMIC than back into the Gintani...
Oh... and all drivin by Jan's 2.0 =)

How about turbo > FMIC > SC > TMIC > intake... I'd have to look at the MCS to see if it's possible to rute the turbo output around the passenger side to a FMIC and then up to the SC inlet...
Talk about a piping nightmare... not to mention pressure drop...
FWIW, my Dodge CTD 12V is a popular twin-turbo truck (although a mod I never plan to do) so there's a lot out there to look at. They run the two turbos sequentially and then feed the FMIC. The turbos are sized so that one is smaller to spool up faster and pump air into the larger one. With that thought in mind, I wonder how hard it would be to feed the SC into a large turbo and then into a FMIC. The idea is to use the SC for low end power and then ramp into the turbo as the SC is running out of steam...
I predict many burned pistons when sorting this one out...
I still wonder what ever happened to the M62 upgrade idea... I like the simpler is better approach of just make the SC bigger, but it seems as soon as the R56 came out, it was back-burnered indefinitely...

thats was the thought i had first. go form turbo to intercooler to sc to TMIC to manifold. but the piping would be hard work and its still loading the SC up.
this is why i thought of the SC to turbo (with the btpass valve to relive the negative preusre for the turbo) to FMIC to intake manifold.
as said before i have seen this work before. all you would need is an RPM and WOT switch. then as the desired rpm where hit (ie when the turbo was spooling and reducing the preusre in the sc to turbo pipe) then the valve would open and the turbo could take over.
with this idea you only need a FMIC and you are not using the SC to boost any air once the turbo is upto speed.
cheers

only one change, screw the 2876 and stick a GT35r on there!
Gintani, what effects would the open manifold design (ie the SC and turbo running the same presure) have on the SC?? basically you are going to be running the SC at 2xpsi!
thanks

If you ran the supercharger into the turbo, wouldn't the earlier boost from the sc spool the turbo? Then you could just have combined boost until the sc becomes inefficient and the turbo would be strong enough for it to not matter. Is this how it would work with the sc into the turbo? It seems to me that you might have more problems doing turbo to sc since the sc is belt driven...while the turbo can spin freely while pumping the sc boost into it since nothing solid is driving it.

Wow 35r?? There $1,500...
and full boost at 5,800rpm... but with the SC... damn... wouyld that even fit under neath the hood... haha

Is there any way of getting a count of how many members on the forums hav done a twincharge setup??? I know there are at least 6... Some others have done it but i dont know them or have ever talked to them...

now the Majors old car (single 106mm (2000bhp turbo) out the back) is setup just the same. ok he has a 7ltr V8 but then he has a massive turbo!
its just the smae on a smaller engine. you have to match thing to get them to work.
as for remote turbos not working, there is a US Navy fighter that used to run twin remote turbos. worked pretty well for them and it was over 60 years ago!
thanks Chris.

also what are you going to be doing for throttle bodies?? you are going to need two with this setup.

Im speaking from experience here no pun intended. The piping length needed if turbos were rear mounted would alone justify the lag inherent in the design, unless you have enough torque generated from the engine alone to overcome the lag created. My 2 cents

with the exhaust velocity of the TC I think it would prolly work quite well rear mounted. but the issue would be running the charge pipes back up to the front LOL... there's just no room! LOL

i have found that 2.25inch piping can support over 600bhp though! that kinda suppreised me! also makes you think about all those people trying to run massive intake pipes, is it really needed???
as for the exhaust thing, if you stick with the stock manifold, or a shorty style header the will be much less heat lost. also the total volume of the system will be much reduced.
thanks Chris.
