Holy silicone couplers. Looks better than a bunch of homebrew birdshit fluxcore welds though. Nice

I have a wharehouse of the stuff available... free. Can't beat that with a stick.

So how long have you been running a unthrottled s/c for??

Try using a larger nipple for the bypass signal line, it makes a nice difference..... it closes the bypass faster when stabbing the throttle :)

C) more effcient, less pressure loss
D) less likely to absorb heat from engine


A) Never heard of anyone putting a hole in a intercooler pipe from road debris.

B) My around the radiator setup had only 4 couplers (compressor outlet to pipe, pipe to i/c, i/c to pipe, pipe to t/b.

C) Maybe, but probably not noticeable in the real world

D) Maybe, but probably not noticeable in the real world

A) ive seen people dent piping (greater pressure drop)

B) Right but its easier with less places to weld (like i said its possible but harder and longer) Whats with people not reading posts?

C) Look up WOT old setup (and its for sure, measurable yes)

D) Not according to BEGI/FM (why FM switch to the silicon tubing supposedly)

Someone on CR.net did a great over-the-rad. kit... said it was pretty easy
seems like there is more room for this on the 99+


homebrew birdshit fluxcore welds
these are the best welds...the birdshit washes off, the flux gets burned off, leaving "homebrew welds"...see my bay

I wouldn't stress over the welds. Setup looks good.

Are you running an 8 rib setup? Did you make that tensioner assembly? What about the crank pulley?

Your setup looks nice. I'm aiming for something similar, but with a smaller blower (damn it boy that bitch is big!)

I just ran it for a few weeks. After installing the IC (which is when I went unthrottled) I increased my timing 3 degrees, within hours my clutch started slipping. So I sold all the SC stuff and started to assemble my turbo crap.

Here's the setup Corky built for me. He designed it for use with the hood latch but I use hood pins.

Having had this one for several years, I personally would recommend the approach Corky now uses on his kits. The aluminum tube exiting down from the compressor and then entering the intercooler on the driver's side of the intercooler actually sheds approx 10-12 degrees of temperature from the compressed air before it even reaches the intercooler.

FWIW.

Did you guys check anything with pressure drop?

What about temp gain coming back up the other side?

Entering Air Temps? Leaving compressor temps?

You may find that that intercooler is too wide. Measure the distance between the rad supports and make sure that the intercooler outlets will clear in between.

I chose a narrower intercooler that lines up real well with the width between the turbo and throttle body making it reall easy to fabricate the pipes.

Here'e mine:

yea IC will put the pipes going up where the current readiator supports are. That's not a problem though, as I'll have to make new ones anyway to move the radiator back. I need a good size IC so going smaller isn't gonna happen.
