I often hear the statement that a car is only run on 30% power on average and yet the auto manufactures use a minimum of 1 1/4" hoses for coolant.

I don't understand this reasoning. I used 1 1/4" hoses up to the "T" where the rads are plumbed in parallel, where I step it down to 2 -1"hoses. Even the "T's" were made with minimum restriction in mind. If we have a higher power demand from the engine (which is always used as a reason not to use EWP's), then why restrict it's coolant flow? =20 Todd (what I do can't be called typing) =09 =20 =09 Thanks Todd, I am pretty sure I will follow your example.

Hi Jerry;
    While the basic block is unchanged = from those=20 pictures, I did modify the orientation of the hose nipples and upsized = them for=20 1 1/4" hose when I added the coolant header tank and rerouted the hose = runs for=20 a shorter and cleaner installation. I also moved the turbo coolant to = the=20 coolant header tank and plugged this inlet as I felt the turbulence = caused by a=20 flow return at this point may be somewhat restrictive. Also I believe I = must=20 have had a dyslexic moment when I labelled those pics as it is "RTD", = not=20 "RDT".
    Another point that I'd like to = bring up right=20 now is hose sizes. I often hear the statement that a car is only run on = 30%=20 power on average and yet the auto manufactures use a minimum of 1 1/4" = hoses for=20 coolant. But in our airplanes builders commonly use much smaller hoses = &=20 fittings usually in order to use AN fittings of which I believe AN16 is = the=20 largest (correct me if I'm wrong) and is only 3/4". I don't understand = this=20 reasoning. I used 1 1/4" hoses up to the "T" where the rads are plumbed = in=20 parallel, where I step it down to 2 -1"hoses. Even the "T's" were made = with=20 minimum restriction in mind. If we have a higher power demand from the = engine=20 (which is always used as a reason not to use EWP's), then why restrict = it's=20 coolant flow?

Hi=20 Jerry,
 
Here's a=20 link to the archived message Todd sent when he made the adapter.  = It's=20 got a description, and several = pics.
