DDP Leak Solution Ideas (PICS)

[grimreaper]

Never had one on the supra but my truck sounded like shit with anything exccept fully closed or fully open... I wouldnt buy into the partial open crap. Think what an exhaust leak sounds like... my .02

Good ideas!

Your best bet is to make a flap that contacts the housing in a manner that it can deflect with expansion from heat. like this:

If you give the sides a bend they will flex but still make firm contact with the housing and the expansion should be minimal enough that they will keep there shape and maintain contact.

The innermost edge that seals against the back wall will have the strength of the flange bolted to the housing to keep that in check.

If there are any leaks, they should get crudded up with carbon and seal up for the most part after a little while.

That would be my plan if i had one and had this issue.

i read this 5 times. and i still dont understand.

the easyiest way to stop cheep is this

go get ring crush gasket cut it bend it to the shape of the tug( may have to flatten the side some) add on some silcone ot keep it on there

then simplly bolt it on. Thats how I did mine when i made my ddp ( witch I toosed cause i did not like creep so i made a mega mouth with divder and i had the best of both dp's

low end and top end with no creep

i like this simple idea.
what's a tug? and whats a ring crush gasket look like?


Would recirculating the ddp fix the boost creep problem? I plan to bore out the WG too.
