WIBIMMERS

Thanks guys, she's work in progress.

Aloha,

Am glad you guys taking on this topic and no, am not trolling, just glad to even if in a comical way manage to stir the pot.

running dbilas 44mm itb's and the plate that mate it to the head. it has been shown that 40mm is more than enough for 885 heads. 

Here's the short of it, using pvc because ...

- ease of manual-ability

- 40mm inner dia (optimal for 885 heads)

- it withstands n/a temps just fine

- you can't blow it apart with n/a psi.

- super light

- creases are minimal and super easy to fill in.

you guys should get transarent pvc pipes and plexy glass, make a box, experiment more I say.

see with your eyes what the gazillion of unanswered equations your brains can't visualize.

a aint a sin for sponge bob's sake !

1st) setup previously posted here, i concur, crap and thanks for constructive criticism.

2nd)  1/2/3 + 4/5/6, 13 inch runners, sounded nice, ran well.

3rd) 1/3/5 + 2/4/6 (video) resonance at 10 seconds, cutting off at 4200 rpms, on better ms2 itb, tune now.

Hey, been around e30's for a while and glad ran into you guys.

Aloha,

Frank
