 Coolant hose sizing, 914s are air-cooled? But SHO-914s are H2O! |

I'm gathering data for my 914-SHO conversion about getting the coolant from the front to the mid-engine position. The fitting sizes on the engine appear to 1-1/4" for inlet and 1-1/2" for outlet.
I don't have the fitting sizes on the radiator - you think they'd match, but that's not a given. Still doing more research there. I'd like to get the supply hose down to 1" and the return to 1-1/4" to make routing along the body easier. Any thoughts, experiences from the V8/V6 folks? TIA, |

On my V8 I used Drake 1" hose. Temps always around 165. On my rotary I switched to 1-1/8" hose because the engine runs hotter by design. Temps constant 180.
Either way will work for you. The Renegade Hybrid adapters are very restrictive they go from 1.5" to 7/8", but they seem to work fine. I eliminated all adapters for my rotary. I built just one 1-3/4" to 1-1/8" for the lower rad outlet. |

QUOTE(kg6dxn @ Oct 30 2011, 11:18 PM)  On my V8 I used Drake 1" hose. Temps always around 165. On my rotary I switched to 1-1/8" hose because the engine runs hotter by design. Temps constant 180. I was curious whether 1" hose will work for a V8 setup. I believe I've got 1 1/4", maybe 1.5" now, I'll have to measure. Do you think a 1" hardline will fit down the longs? I'm planning on giving this a try early next year, as I'm largely funny about soft hoses being run straight down the middle of the pans. (IMG:style_emoticons/default/blink.gif) The only thing I really want to avoid are 90* bends. I've got a dedenbear electric water pump and I'd hate to bog it down with restrictive flow... |
