On another truck forum a guy said i wouldnt only have lag but hellacious lag with this as a remote mount turbo setup... but i get diffrent opinions from everyone some say use a 1.06 a/r some say use bigger if going with the GT4094 some say use the GT4202r with a 1.0 a/r

I'm trying to make atleast 450 rwhp on a 5.6L titan with stillen longtubes and jim wolf camshafts.. they are 119deg@.050 lift
any idea if i should just go ahead and buy a 1.06 a/r or not? I can deal with a little lag like taking to 3,800 rpms to hit full boost but if it is going to take up to 5,000 rpms to get 5lbs of boost i will swap out the a/r

anyone run a similar setup before? The reason i went with such a large a/r was i was told you definatly don't want to choke off the turbo and put added backpressure plus i fugured i'd need the largest housing after going with a built motor next year and trying to hit 650-700 rwhp..

Your gonna have a lag issue.
Are you on stock manni's? how far back is the turbo?
What's the exhaust route consist of? wastegate?

 

no i have stillen longtubes it has 1 5/8 primaries and 2.25" collectors the pipes immediatly after the longtubes are right now 2.5" for about 4' then it hits 2.25" where the catback starts.. the wastegate i was told to buy was a 60mm tial wastegate with a 6.5lb spring..
piping going to the motor will be 2.5" and will go to a intercooler ( should i get a large intercooler rated for 650-700hp or stay small for 450-550 hp region?)
the piping will most likely be between 8-12' in length i'd imagine..

i have no issues with having to buy another exhaust housing but wanna make sure i get the right one for low lag and use this one till i get the motor built some time next year..

 

i was just thinking of shortening the whole thing by about 6-7 feet and possibly mounting it under the driver seat area under the cab of course,lol and build a cross over pipe from the passenger side manifold and that would cut out quite a bit of tubing, i really want this to work as best as possible, need some help from the pros out there spending soo much on equipment like 8,300 or so i cant afford to pay a shop another 2-3k just to fab up everything..
