Thread: New setup and build....Updated 5/25/12...723whp!!!!!!

2.5" turbo inlet will be fine, change the outlet to 3"...as far as the vbands, put then on the turbo outlet and the throttle body

You should just buy my shell

I dont want to have V-bands all around as with engine movement even the slightest v-bands have the tendancy to pry apart causing boost leaks under acceleration. Gotta have couplers somewhere to allow give. Easiest place is the throttle body and turbo and keep the intercooler connections v-band. I already have the 3" piping so again both intercooler connections will be opened up and have the v-band flanges welded on in place of those long 2.5" connections. 2.5 to 3" coupler from the turbo and then a 3.5" to 3" 45 deg coupler from the throttle body to the piping.

Pretty simple, cost effective and should look sick as hell.

if they are shitty vbands

i trust a vband over a coupler any day especially with high boost

He means use couplers on the intercooler sides and vband on the turbo and throttle body.

Again this info was gathered from some of the high hp outlaw honda builds. Several have reported that during acceleration with v-bands all around that they experienced huge boost leaks from top quality v-bands and had to go back to using couplers either at the engine connections or intercooler connections to allow for some flex.

As for coupler, a good reinforced 4 ply coupler and good t-bolts is very unlikely to fail. You look at what boost numbers some turbo diesels run and are using couplers and t-bolts. lol. The most boost I plan to push eventually from the 6766 is probably right at 40psi. If all goes well im hoping to eclipse the 800whp mark by 35psi.

Again im not just making this stuff up. And those guys are using completely solid metal mounts all around and im still using urethane mounts. So im sure my engine moves considerably more than theirs do. However id rather have that cusion on the case and gears to help than not have any engine movement at all. Plus its still minimal movement. Not enough to cause issues

Again id rather keep it simple. Again its not like nice matching black couplers w/tbolts are hideous to look at. haha. Worm drive clamps...Now those are hideous. haha

hey do what you want i will just stand back and watch from here. gl

Morgan, again your input is appreciated and after seeing a couple builds reporting issues with having v-bands all around id rather take the safe tried and true way.

Again thanks for the input and suggestions.

i know i saw your responses on honda tech and people were saying the tbolts also fail cant hurt to try tbolts so go for it
