ok .. so i have all the parts to do this basically.. and it's an idea i've been thinking about for a while..

i have an ss/tc stock turbo setup.. and the procharger setup.. as those who have read my build thread when i went below a 2.95 pulley i had some issues with my tensioner and getting things to work..

what i was thinking .. throw the stock ss/tc turbo on the car.. run it like 7 or so psi (off the wastegate) and have the turbo outlet go from the turbo to the procharger inlet..


that is the inlet currently

the idea about this.. basically it would have the ridiculous low end torque of the ss/tc turbo.. and the top end of the blower.. (hows that for something that sounds backwards lol) keep in mind the C1 blower is used on v6's as well as 4 cyls and usually has much better success on bigger motors (not that i didn't like it at all)

i would be running the blower on a 2.95 pulley which would push about 9 lbs of boost.. ( i could get a 3.2" pulley which is 7 psi if need be)

to do this would i need a second BOV bettwen the turbo and procharger?

i know this is a crazy ass idea.. however i figure i have all the parts .. maybe look into what to do until i could sell something

also.. how bad would it to be to run the ss/tc setup without coolant? (so it would just be oil cooled?)

also i know this will probably be killing the motor.. or getting very close to it..however i also have a head that needs to be ported with some valve springs.. so that'll help that a bit with temps and cyl pressure

i know i know.. going straight turbo is better.. this idea is only thought of cuz i have the parts to do it .. my plan was to run straight ss/tc turbo at 14 psi or so .. and eventually swap to the BNR 2871 upgrade

i also know the ss/tc turbo is small for the 2.4 and will boost almost instantly but that'll be alf the fun

 

guinie pig time! lol. seriosly tho, i say do it just to see how it works. nobodys tried that.

 

lol i'm always the Guinea pig lol.. no 2.4 has done a procharger cept me that i'm aware..no one has done the ss/tc setup on a 2.4 .. lol it could be very interesting.. it could make it so i could hit alot of whp and wtrq lol thats for sure i mean even if i push 250 wtrq on 7 psi from the turbo.. then like figure it would be like 220 whp .. plus the blower.. would put it at like 300 300 lol maybe more with 9 psi from that .. these are all ricer figures though.. but still

 

You wouldn't need a second bov cause there's no throttle plate in between the turbo and blower your existing one would be fine but I guess it wouldn't hurt

 

my concern is because the 2 turbines might not be in sync or something cuz one is belt driven and one is exhaust driven idk how that would jive.. i dont THINK i'd need it .. it's just curious lol

 

Ya I mean the boost will still flow through no problem and the more I think about it I would run one just to make sure it doesn't surge or just use the factory bpv on The k04

 

i have a blockoff plate for the K04 but yea

 

Ya either or would work I would think

 

wouldn't that over spin the procharger?

 

Sub'd

 

No.the prochargee is belt driven so it's spinning with the motor.Adding boost before the procharger will not make it spin any fAster.Even if he put a pulley small enough to overspin it,the procharger is still more efficient than a m62.

 

precisely.. I might give it a shot.. just cuz.. lol .. have to talk to the guy helping me with the turbo **** see if he wants to give it a quick shot lol see what happens

 

sub'd for this badass idea

 

sub'd

 

Research into compound turbo setups, might help a bit. Other then that, have fun tuning hahaha

 

i would cool the turbo just my 2 cents.


man that air into the procharger and than into your motor is going to be CRAZY hot

 

idk.. the procharger runs VERY cool normally .. however it might depending on the turbo.. but the turbo would only be running around 7 psi..

as far as tuning.. i done think it would be very bad.. as it wouldnt be like a normal twincharge.. it would be more like a compound charge b ut 1 sc and 1 turbo lol

 

i dono man !!! lol just do it

 

X2

 

wait a minute... this sounds exactly like the idea I had months ago. I wanted more power out of my TD05H setup, and thought of compounding a centri blower in with a small turbo to help the low end.

I think it would work, and I am still considering it. Im now just waiting on my car to get here from the states to get it started.

Some ideas though, I think you should run the centri blower into the inlet of the small turbo, instead of the small turbo into the SC. Even though on the low end the SC isn't spinning very fast, it should still aid in that small turbo spinning, just a little bit. Then the small turbo can compound the airflow from the SC and you wouldn't need to make ANY changes to your current charge piping. You also shouldn't need a second BOV or bypass valve. It should work with your current one. Please correct me if im wrong though, because I am actually very interested in this idea and have been for about 6 months now.

EDIT: Wait a minute, you would be doing the opposite of me though.. You would need to change your hot side piping slightly, but I would just run the SC's outlet into my turbo inlet.

EDIT 2: From what it looks like, you need to be able to flow A LOT of air through the centri blower at a low pressure ratio, because that small turbo is going to compound the boost. So you will need a much bigger blower then what you have to make a significant amount of power to warrant having a "twin charged" setup. I was looking at the Rotrex C30-94(flows 640cfm) or the C38-61/81. I believe the C38 blowers would be best because you can run a large pulley and still flow a lot of air, in turn keeping your manifold pressure at a lower level. You don't want to be running 25+psi on these stock sleeves.

 

Doooo eeeeet

 

'id be going from turbo outlet to SC inlet so i would be doing it the same you were looking at..

so i'd be going the same method you were the c-1 blower supposedly can push 1000 cfm at 24 psi i want to keep psi below 20 somewhere in the 15-19 range lol. this would have me running the 10 psi pulley i have frmo the blower (2.95 instead of the stock 3.2 i had)

 

Ya, but 24psi on what size motor. I guarantee its not a 2.4L. It just doesn't make sense to me to run the smaller/faster responding FI Unit(the turbo) through the larger, slower responding unit(the SC) when its not another turbo. At least with a larger turbo in there the smaller one will spool the larger one, but in this case, you can't spin it any earlier. Since the blower is the unit used for the high end(power comes on later/higher in rpm range) it should flow into the smaller unit(turbo) so the smaller unit has no obstacles or restrictions. The air should get to the motor as quickly as possible to make that low end power you want then once you move higher in the rpm range, the blower starts to shine.

 

hmm good point.. i'm going down to PA to do some work on the car after the new year.. we'll see what happens .. lol the problem is the largest pulley i have is the 2.95 .. i based it around the turbo to SC cuz that was the easiest mode of setting it up and the turbo doesn't need to spool up any quicker lol it'll spool by like 1800 rpms with no help

 

expect to see some pretty amazing huge boost numbers in the manifold... 03 cobra guys were doing this with the hellion hell raiser kit... stock blower pulley waslike 9lbs and they had the turbos set for 8lbs... intake manifold showed like 21... one guy pullied down and forgot he had the boost on the turbos at like 12lbs and it made something like 56lbs of intake pressure lol
