coupler vs. v-band

[boostedinthe843]

My buddy is making some ic pipes for my car and i was wondering should i go with regular couplers or the v-band style, or does it even matter?

I'd go with the v-band style clamps.

 

[mitsu-luver]

if you got the dough defiantly go with the v bands! they seal better and you dont have to worry about a hose popping off

I don't know if I would go with v-band clamps for an intercooler setup. I don't believe v-bands allow much flex. If you want clamps, look at AdelWiggins clamps. There is another brand, but the name isn't coming to me right now. Maybe if my brother sees this thread, he'll post it up.

I would go with V-band clamps,so your couplers don't pop out at high boost

Accufab is the other brand. From what I've read online, people seem to like Accufab more than Adel Wiggins. Hella expensive and hella cool.
Throttle Bodies

I've also seen these, which say they're specifically for intercooler piping. Only available in 3" though.

If you are able to, V-clamp it.

v-clamp

Vband is a needless expense for a car with less than 30psi. Tbolt clamps and a bead/ridge on the piping is all that's neccesary for a solid consistant seal that will flex when needed.

How big is the current IC? Get a big side exit one. There will be much less pressure drop, and work well.

12x29x3,

im tryin for a short route style also

Clamps and rolled lips on the pipes work fine. Just make sure you use t-bolt clamps. The worm ones won't hold (been there done that as a quick fix <- didn't stay fixed). I couldn't justify the cost for v-bands without running boost so high as to pop a coupler every week.

He speaks the truth! Completely unnecessary on a "low" boost car, save the vbands for the guys with the 3" turbo outlets. Unless you're rich of course, then go for it BUT like dsm-onster said, you'll have to include a flex point. I've done 23psi on tbolts and silicone and have never had a hose blow off. Haven't gotten around to beading my pipes yet either.

Do you use hairspray to make the couplers stick?

 

[boostedinthe843]

yeah well since its gonna be a custom job done by my friend i dont really have a budget on it.and i have a friend who has blown a coupler off on a few occasions dont know how tight he had his though so.

I agree. I have seen this type of connection withstand 50 psi. Unless you have all solid motor mounts I would allow for a fair amount of flex between the engine and the intercooler.

you could be crafty and use a link bar to limit the flex of the coupler. I used a v-band at the TB and then Hump hose at the Gm-MAS. I did it for easy removal.

As mentioned...V-band is an expense that can be spent better until you get into the 30+PSI range. T-bolts and beaded pipe will handle into 30PSI (and really even higher).

But I wouldn't worry about a v-band setup until I was in the mid 30PSI range either.

 

[1992awdlaser]

I will be going with all v-bands after I build my engine. BUT, I will be using a water to air intercooler so I don't have to worry about needing any flex. With a fmic I would highly recommend at least one regular coupler for both the lower and upper intercooler pipes. If you use all v-bands, chances are you will crack the intercooler.

No. I did spit on them tho!

A spring loaded t-bolt may work better.
Heavy Duty Spring-Loaded T-Bolt Clamps - PartsSystems

They also have constant torque

Or, bicycles.

boostedinthe843, as for the IC type, don't try to ask two different questions in one thread. But start here:
