no downpipe
 

We just boosted my freinds civic and we have not put a dp on it yet. It will not spool the turbo until about 5k rpm.
Would running no dp cause this?

Re:no downpipe
 

prob.ly not.

but with all those hot exhaust gas, somethins going to melt in the engine bay for sure :-X

Re:no downpipe
 

what size turbo ??????

Re:no downpipe
 

14b but I think it still should spool before 5k rpm and will only get up to 5 psi on the factory wastegate which should be 8

Re:no downpipe
 

pwned by leakage???

Re:no downpipe
 

check your vacumm lines... open dp would spool faster!! so something is deff wrong with your vacumm lines probly.. check them and come back

Re:no downpipe
 

It is not an open downpipe. There is not one at all so I guess you could call it open 02 housing? :-X

Re:no downpipe
 

wait does it have the o2 housing? or nothing at all? anyway id still check vacumm lines.. charge pipes... and get atleast a dp to get the gasses under the car or something..

Re:no downpipe
 

you prolly either have a boost leak or a fuxored wastegate

Re:no downpipe
 

I have no downpipe, nothing melted in the engine bay, and im fully boosted by about 4500 rpms.

everything is dirty as ----, but it still spools fine.
