b6t at 16 psi!

[mikemounlio]

So got my rocketchip back today. The car holds boost great and pulls very hard. Will need a better clutch tho. 2nd gear it started to slip i let out after 3rd had nothing. Clutch is cooled off and fine now but it cant take that very much more.

The b6t festiva must be crazy at 16psi. Slipping clutch and with the capris weight it was fun.

Found an oil leak i have to fix before i really get to enjoy the capri tho.

The best 160$ mod i think i have ever done to a car.

What boost level did it used to run?

Stock gauge (no clue if it's even close to the right number) showed it to hold firm at around 7psi.

At the boost controllers lowest setting it held firm at a stock gauge level of 12ish psi. But an old oil return line broke. I'll have it fixed and new oil tomorrow night and will check the damage.

The oil drain from the turbo tends to get rock hard and brittle with age. Be careful with what you replace that hose with. I used a pre formed heater hose that I cut to fit. I found it by rooting through the coolant hoses at pep boys. I was skeptical about using heater hose for oil, but it held up for 2 years before I found a good factory replacement. I think I wrote down the part number for that hose somewhere, I'll look for it.
If the hose is kinked at all it will back up and you'll burn oil.

Isn't it more common to use metal braided/mesh hose for that?

I HATE braided hose. It is hard to work with (pokes your fingers all the time) will rub through just about anything it does get up against, and if that happens to be a wiring loom, is also conductive and can short out wiring. Also, if you run it too close to exhaust you aren't much better off than just running a bare hose next to exhaust...the steel will pick up the heat and put it right into the hose anyway. I now use two-braid hydraulic hose for just about everything. It's 10x tougher, easier to work with, has a nice rubberized outer jacket, is about 1/3 the price of "AN hose" or stainless braided hose or whatnot. Also, if you make a tight bend with braided hose it will kink/collapse. Hydraulic hose holds its shape a lot better because you're getting 5 layers of material.

Most factory turbo drainlines are hardlines though. They have flex-sections like exhaust piping. I don't like those for the conductivity reason. They inevitably (on most cars) run near the starter. If you don't unhook your battery before you work on stuff it's easy to short out a starter terminal and burn a hole in that line, lol.

Haha, ok. i only helped once with a turbo build and thats what we used. Car didn't last long after that and i have seen a few other people use it. I think people only dont use hydraulic hose because it costs more right? Thats why we went with the metal stuff-it was cheaper.

I think I will use heater hose and buy enough for 2. Keep the spare in the trunk. It looks like the line just split from age and such

Heater hose will sweat oil. I know because I temporarily used it on a hydraulic return. Hot oil might make it worse.

Use some genuine Hydraulic return hose that's rated 150psi and barbs/clamps, or go fancy with copper tubing and compression fittings, it'll double as a oil cooler. Do a wrap or 2 like master cylinder lines for stress.

Double hose clamps on barbs, never look back.

Silicon heater hoses do, i dont believe the other type of rubber does but i cant confirm that. Fuel line could work too if you wanna do it cheap. Not that 4ft of hydraulic hose really costs that much...

Not at all. Hydraulic hose is a couple dollars a foot online. Approximately the same as buying heater hose at the parts store. It's probably more walk-in price by the foot at local stores, but if I'm doing something like that I usually have time to order online. And when you're talking about a 12-18 inch long oil drain that's not a lot of money. That stainless braided stuff is 3x the price per foot. Probably not as bad now that there are likely plenty of chinese alternatives on ebay...but it sure used to be very expensive.

Yeah, heater hose for oil lines is not a good idea.

I'm still curious about what the rocketchip does. Does it work worth aftermarket turbos. Is the tune different, or just for higher boost numbers.
