d.p.n.s Posted October 16, 2010 Share Posted October 16, 2010 what are your guys views on this? i am going to be twin charging my ca18det for my van im not to worried about the room as i will make it fit/work. but what im after is views on the best way to make it work i have seen setups ranging from supercharger feeding big turbo to using the supercharger as the inlet manifold and having a throttle body on it with the turbo blowing threw it. i was thinking more on having the sc feed the turbo and have some sort of valve to shut it off . dan Quote Link to comment Share on other sites More sharing options...
jakesae101 Posted October 16, 2010 Share Posted October 16, 2010 theres quite a bit of variation on setups id try to go with something similar to the hks twincharger kit for the 4agze as they seem quite an effective setup Quote Link to comment Share on other sites More sharing options...

Mike-e Posted October 16, 2010 Share Posted October 16, 2010 its a neat idea for smiles per mile but it dims in comparison dollar wise and reliablility wise to a well sorted single turbo setup these days Quote Link to comment Share on other sites More sharing options...
Simon Posted October 16, 2010 Share Posted October 16, 2010 its a neat idea for smiles per mile but it dims in comparison dollar wise and reliablility wise to a well sorted single turbo setup these days I aslo see it as a novelty rather than something you would do for relyable gains.

UTERUS Posted October 16, 2010 Share Posted October 16, 2010 ^this, i thought about twin charging, then decided a variable geometry turbo would be simpler. Quote Link to comment Share on other sites More sharing options...
karmagedon Posted October 16, 2010 Share Posted October 16, 2010 a setup that I though about was turbo-SC-plenum. But infront of the SC having a wastegate to divert gas past SC once turbo spools too much Quote Link to comment Share on other sites More sharing options...
Mike-e Posted October 16, 2010 Share Posted October 16, 2010 best way ive seen it done is having a simple flap valve with a pressure switch. you roll outlet of turbo and outlet of super charger into a Y shaped valve. low revs supercharger pushes the valve to one side while turbo spools, at whatever boost you require to have your turbo spooled sufficently the pressure switch tells ecu/relay/whatever to cut the power to the super charger clutch, air pressure from turbo clonks the valve flap over the supercharger outlet pipe. hey presto Quote Link to comment Share on other sites More sharing options...
karmagedon Posted October 16, 2010 Share Posted October 16, 2010 That is a pretty sweet way of doing stuff. Sounds like it will work well Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted October 17, 2010 Share Posted October 17, 2010 Did I draw you a picture that day you came over Dave? I'm gagging to build such a set up myself. I scored an RB30 and a 25DE head for just that purpose. (Because everyone knows I need more projects. ) Quote Link to comment Share on other sites More sharing options...
d.p.n.s Posted October 17, 2010 Author Share Posted October 17, 2010 yeah what we talked about bart made a lot of sence to me. now i know some people dont see the point in this but everyone is differant and this is something i have wanted to try for a long time so im going to do it and it is going to happen so i just need input from those that can help. cheers now after reading alot about differant setups i am wanting to go with 1 of these 2 ideas. sorry about the shit house drawings lol cheers dan Quote Link to comment Share on other sites More sharing options...
BobbyBreeze Posted October 17, 2010 Share Posted October 17, 2010 Just have the turbo boosting through the SC. Easiest and most effective way - you dont have to disengage or bypass the SC after the Turbo comes on boost as this would negate most of the positive effects of having a twin-charged system.

Mike-e Posted October 17, 2010 Share Posted October 17, 2010 you start getting astronomical intake temps compressing shit twice, which is why shit doesn't usually roll that shit Quote Link to comment Share on other sites More sharing options...
phr34kr Posted October 17, 2010 Share Posted October 17, 2010 How about running 2 intercoolers im sure planes used to run this set up but with 2 SC instead of the turbo. Turbo----> intercooler---->SC---->intercooler---->TB Quote Link to comment Share on other sites More sharing options...
BobbyBreeze Posted October 17, 2010 Share Posted October 17, 2010 AFAIK that is how all of the proper setups were done - i.e. aircraft, Lancia Delta S4 etc. You just run an IC between SC+Turbo, and one between SC+engine. Quote Link to comment Share on other sites More sharing options...
