Sorry I forgot to mention I used super high temp industrial epoxy glue to fill the crevasis inside the elbow, as willwren mentioned they are quite rough inside because of the joins wich _need_ to be filled/sanded/diegrinded ect. I mentioned the sanding part I guess, just not filling the gaps inside wich are... well decently large. That glue once it sets is ROCK HARD and very sandable. Glue sticks to plastics very, very well. I considerd some type of automotive filler but a scared of it breaking inside and chunks going into the motor, atleast we have a MAF screen on these cars for large particles.
I also have to agree the accordian tube will hurt performance potential of the FWI a bit. atleast its only 6" or so, I wonder if the factory used accordian style because it would cool the air just a teeny bit before entering the TB. With 6" it should not have hurt flow THAT bad, cuz its next to the MAF screen wich smooth it out a bit anyway.
My next thing on my list is to find a non accordian tube around that length. I am sure the speed shop my friend works at should have something in 3" pipe around that size, perhaps I could even find a honda rice pipe to join the nice smooth inside cavalier pipe. Who knows. Then to re-make one of these again I could forgo the hours of smoothing out the inside of the plumbing elbow. and only have one join then instead of two which also would help smooth flow. Who knows I just have way to much time on my hands. I go for walks at the wreckers for exercise sometimes hah. Just to poke around see whats there.
Yea sorry that is ABS too btw its black not PVC thats the white stuff. I just renovated my basement and have PVC stuck on the brain.
Maybe someone knows of a part number they could throw around of pre-made shorty rice pipe like a foot n a half long or so. Maybe for an integra or something. I really cant recall perfectly, but dont the honda motors intake from the rear and the exhaust is in the front so they always have longer intake tubes? Thats why the cavalier intake tube I pirated is so long anyway, its gotta get from the back to the front.
