well when i installed my stage 4 parts it was a mess, i had to be done in a weekend and i could only work from 5pm to 12 on sat and sun. needless to say when i was trying to get all the pipe for the the IC to fit it was a painfull prosses and i made a few trips to pepboys to get some of the cheap rubber cupplings with the thought of just getting the better ones once i knew what i was going to need. well i just kept passing over them until yesterday i was working on fixing a boosting issue i was having.

so i was in 3ed at about 3k when i went WOT the car pulls hard then the w/m kicks in and it pulls even harder when POP..... no more boost...




oopps:D:D:D

its funny now, but after i the pop i looked under the hood and the wya that was hooked up the hole was so i couldnt see it... i wasnt happy i was thinking the worst. but now i think its funny, i thought you guys might to.

im not even going to try to take it back, not worth dealing with the people there.

Jonny, that pipe is thicker but it's still going to keep you up at night.

The main reason rubber pipes burst is heat.

They're more pliable when heated, and stretch more...and eventually pop undr pressure. (Nick's comments were right on the money.)

The major reason you use silicone is because it's heat resistant to 300+ degrees and keeps its shape. Find a decent three-ply silicone elbow for $30-40 and you'll never have to worry about it.

Assuming you're using 2.5" piping, and your IC has 2.5 IN/OUT. Just to give you an example of what's out there. 3 or 4 ply silicone couplers. 4 ply being better. Just look at the angles you need and take it from there.

TB-Intake= 2.75-2.5
Intake-IC= 2.5-2.5
IC-Intake= 2.5-2.5
Intake-Turbo= 2.5-2.25? Check your turbo's size (if TD04 I think it's 2.25")

This was just a quick search, look into more and you'll figure it out.

Bottom Coupler attaches to IC : 2.5"-2.5"

Top attaches to TB : 2.5"-2.75"

Is this custom piping? Cause 3" is kinda big from posts I've read. Some people are running big hp with stock intakes and they are way smaller than 3". 2.5" I would think is more appropriate. Do a quick search on intakes there's lots of info on that subject.
