Upgraded my Intercooler lines

Update from the future:

I already have a killer chiller installed and my H/E bypassed. I was still finding my coolant temps to be warm and not cold after cruising on a hot day. My current setup is IC > TANK > PUMP > KC > IC.

I figured the non-insulated hard lines in the system must be hurting my temps. I searched for hose and came across this:

3/4 Purosil 80 series heater hose. It is insulated and good for -65 to 350*F. I bought a 16' roll. The seller accepted my $20 offer.

Here are some pics of the hose installed. Almost matches my pulleys.

I routed the lines out away from the engine. There are two 1" holes underneath the airbox which are right above the IC pump. I was able to fit this hose through those holes. The edges of the holes were very dull so i'm not worried about it cutting the hose.

Now my system is as much 3/4" as possible. some of the stock hard lines neck down to almost 1/2"!

I'm yet to test the difference. If it still needs more i can now easily further insulate with pipe wrap if needed.

6/24/15 Quick update: I don't have any measured exact temperatures but the upgrade made a big difference. As stated, before the temps after a 30 minute drive were cool to warm. Now with the new lines the coolant is cold to ice cold in the tank. This is a big change using the finger measuring tool.

Your routing looks optimal, those holes that the hose is running through will cut through the hose over time. It may take some time but vibrations from the car running will eventually cause it to wear through. The holes/hose need to be coated with something to prevent this. There are a variety of options that i will leave to your imagination.

A step further would be to insulate the lines with pipe insulation available at stores like home depot and insulate the tank.

Good Work :beer:

I'll keep an eye on the hoses in those spots. I don't drive it much. If I start to notice wear I'll try wrapping the hose in something. I'm thinking some kapton tape.

smart! i have thought about eliminating those hard lines. They do neck down really small and get really hot. I might do something similar someday. I have all my lines insulated in rubberized pipe insulation.

Any comparison of the IC fluid temps or IAT2 temps before and after the hose swap?

This piece improves the size of the inlet/outlet to the blower intercooler.

The biggest improvement will be relocating the IC resivor out the hot engine bay and to larger size

Don't know how I missed this original thread. Good idea as mentioned above the restriction is now at the IC manifold and can be corrected with Cobra Engineering's bits. Are the hoses you installed sweating?

Not sure actually. I didn't put many miles on the car since this mod before I put it away for the winter. I'll keep an eye on it when it comes out in a few months.

I've seen the cobra engineering kit. Kind of expensive for not knowing how much it helps. Is the inlet the restriction or the core itself?

 

[SVTDice]

The restriction is in both, Take a look at what the Lightening guys did. However the Cobra Engineering kit looks like it WILL help with that restriction. Removing any restriction in any way shape or form will have cooling benefits.

Any links to the Lightening work? I'm never in their forum.

I'll post a link below. Ontop of that, Alot of the guys are also upgrading all of there hoses to allow more flow as well.

Weird how with the promise shown in posts 109 & 128 the thread drops off in 2011. Guess I'll contact the vendor directly. Thanks!

Any updates OP on your IC temps after removing hard lines?

Car has been in storage all winter. Right now the fuel system and blower are off the car for upgrades. It will be a month or so before I have it back on the road.

Hey Moose, did you ever get iat2 temps and see what you’re running?
